▼ The relevance of the use of molecular tools in the
global epidemiology of Mycobacterium tuberculosis complex (MTBC)
cannot be undermined. Molecular epidemiological studies of the MTBC
in Nigeria are not extensive, and to date, there has only been one
detailed report. More strains are therefore needed to be genotyped
in order to give a clear indication of disease transmission chains
and to highlight routes of infection particularly with respect to
zoonotic tuberculosis. This study therefore focuses on the
identification and genotyping of MTBC isolates in south western
Nigeria, with emphasis on interactions occurring at the
human/livestock
interface. The molecular epidemiology of M. bovis
strains in Hluhluwe-iMfolozi Park in South Africa was also
undertaken. Prior to this study, a pilot study was initially done
to establish techniques, using samples from Belgium. Mycobacterium
bovis strains were first identified in Belgium using the Multiple
locus [variable number of tandem repeats] (MLVA) technique and
analysis was done using capillary electrophoresis. In this study,
the Belgium isolates were repeated using MLVA and analysis by
agaorse gel electrophoresis and the two analysis techniques
compared. Human isolates (136) and livestock isolates from cattle
(50), pigs (12) and goats (5) isolated in Nigeria were also used
and species identification of the members of the MTBC were done
using the deletion analysis PCR technique amplifying RD1mic,
RD2seal, RD4 andRD9 regions as well as spoligotyping. Seventy four
positive MTBC strains (humans and livestock) were genotyped using
16 VNTR loci. The discriminatory ability of the 16 loci MLVA was
compared with spoligotype data on 33 MTBC strains. Mycobacterium
bovis isolates from buffalo in HluhluweiMfolozi Park (HiP) South
Africa, were also genotyped using the 16 loci MLVA and
spoligotyping. Results indicated that agarose based MLVA is as
discriminatory as the capillary based MLVA. Furthermore, the
relevance of molecular techniques in the rapid identification and
genotyping of members of the MTBC, especially in a tuberculosis
endemic setting like Nigeria, is also highlighted. This was clearly
seen in the identification of undescribed spoligopatterns of the
LAM 10-CAM M. tuberculosis strains in humans as well as the
identification of undescribed M. bovis spoligopatterns in livestock
isolates. The prevalent M. bovis strain (SB0944) in Nigeria was
also identified in a human isolate. Also, two classical M. bovis
strains were identified in two human isolates obtained from cattle
traders, thus suggesting the influence of close interaction between
infected animals and man as a means of zoonotic tuberculosis
transmission. Mycobacterium tuberculosis was also identified in
three isolates, from cattle, pig and goat; with the goat isolate
having a spoligopattern (EAI5) typical of strains indigenous to
East Africa and India. This study demonstrated the prevalent
strains of M. bovis and M. tuberculosis circulating in Nigeria with
SB0944 the predominant M. bovis spoligotype and LAM10-CAM the…

▼ In this thesis, I investigated the relationship
between host and pathogen in multi-host and multi-pathogen systems
at the
interface between
wildlife and domestic species. The term
“epidemiological interaction” was central to my thesis, and was
defined as “any ecological interaction between two host populations
resulting in the transmission of one or more pathogen”.
Epidemiological interactions are related to the processes of
transmission between hosts and I investigated how these
epidemiological interactions between different host populations
could be investigated in a given ecosystem. I developed two
research frameworks to estimate these epidemiological interactions:
1) an a priori approach based on the host data and assuming that
the mobility of hosts and the resulting contacts between host
populations would be crucial factors influencing the
epidemiological interactions; 2) an a posteriori approach based on
the pathogen data, assuming that epidemiological pathways
previously used by some pathogen species can be used in the future
by other pathogens. The animalpathogen model used to test the first
approach was the bird-avian influenza viruses’ model. Longitudinal
counting and sampling protocols of domestic and wild birds over two
years were used to analyse community composition and abundance of
hosts to compare with the prevalence of avian influenza viruses. I
could, for the first time, show a persistence of low pathogenic
avian influenza strains in an African ecosystem, and investigate
the relationships with both the potential maintenance hosts
(Afro-tropical ducks and resident species) and hosts that
introduced the virus into the system from Europe or Asia (paleartic
migrants). With the estimation of epidemiological interaction using
host community data, I estimated the contact rate between wild and
domestic avian compartments (intensive poultry, backyard and farmed
ostrich compartments) and assigned a risk to this interaction based
on dynamic and non dynamic factors for each bird species. This
approach highlights the species or seasons at risk for the domestic
compartments (or for the wild bird compartments depending on the
perspective) in order to orientate surveillance or control options.
This type of data and framework can also be used in mechanistic
modelling to predict the spread of a pathogen after its
introduction in one compartment. I tested the host approach in a
broader dataset at the Southern African region level with similar
counting and sampling database in multiple study sites, showing
that the variability of host communities across the region could
explain the variability of pathogen detection (however, finding a
causal relationship was impossible). Finally, I theoretically
developed the pathogen approach by combining tools used in parasite
community ecology, molecular epidemiology and social network
analysis and gave a theoretical example using a rodent and human
macro and microparasite dataset. This thesis has explored the field
of transmission ecology and offered ways to quantify the processes…

▼ Rabies is a zoonotic, rapidly progressive, fatal virus which targets the central nervous system and is mainly transmitted by bites and scratches from domestic dogs (Canis lupus familiaris) acting as the main reservoir of disease. Not only dogs and humans play a role in the dynamics of rabies, it is also known as a disease that is of conservation interest. Wild carnivore populations have been affected by rabies virus over the past 20 years. The design and success of long-term rabies control programs aimed at domestic dogs in developing countries may be affected by many factors such as high density populations and high turnover rates.
The objective of this study was to collect data through a household-level census in three rural communities in the sub-district of Bushbuckridge, Mpumalanga Province of South Africa, bordering a large privately-owned conservation area. With this data we aim to assess rabies-vaccination coverage and other factors that might influence the success of the on-going vaccination campaign in the study areas. A descriptive analysis of household characteristics, dog demographics, and contraception demand was performed.
A total of 1086 households were interviewed representing a total of 5115 persons and 413 dogs. Dog densities were found to be 169 dogs/km2, 128 dogs/km2, and 133 dogs/km2. We found that the dog:human ratio is 1:11 and 1:15 in the three studied communities. Of all the households included in this study 227 (21%) were DOHH and 863 (79%) of them NOHH.
More than 60% of the dogs were found to be free roaming in all three communities. The dog populations were comprised principally of adults (>1 year of age) which made up 52 - 69% of the dog populations in the three communities. The sex ratio of the dog population in all three communities is skewed towards males. The average number of litters in the past twelve months ranged from 1,0-1,3 litter(s), the mean size of the litter was 5,0-5,2 pups and the mortality in the first week after birth 0-45,9%. Neutered dogs (<12%) are not a common finding in any of the three communities. Owners were willing to pay an average of $8 for the 2-year contraception injection.
The vaccination coverage range in each of the three communities was 48.6%-57.3%, 68.7%-77.4% and 53.3%-77.8%. We did not detect any significance between confinement characteristics and the vaccination status of dogs in the three communities. Our results show that over 85% of dogs in all three communities were vaccinated during a vaccination campaign where house-to-house visits were carried out.
Veterinarians, medical practitioners, and health authorities have the responsibility to apply intersectoral collaboration under the motto of ‘One Health’. We need to strive for a high level of risk perception among dog owners and an increased belief in the benefits of vaccination through public education activities. Proactive and sustainable vaccination programs in the Western World have proven their efficacy in the eradication of domestic dog rabies; this should provide a motivation and a…

▼ Land use is a major driver of human disease risk. However, few studies have examined this driver in livestock, which are often integral components of human lives and livelihoods. We examined exposure risk of cattle in northern Kenya for
three high-impact pathogens: Brucella spp. Bovine viral diarrhea virus (BVDV), and Leptospira spp.; across two land use types: private ranches (low intensity cattle ranching, high wildlife densities) and communal ranches (high intensity cattle ranching,
low wildlife densities). Cattle on communal ranches had higher exposure risk for Brucella, while cattle on private ranches had higher Leptospira exposure risk. We suggest that variation in contact patterns between cattle and wildlife may be driving the
the pathogen specific effects of land use on exposure observed. Ultimately, understanding relationships between land use and disease could help to target specific pathogens, host populations, and sites for disease management and control
efforts.

▼ The primary purpose of this thesis was to investigate the prevalence and distribution of potential pathogens circulating in wild turkeys (Meleagris gallopavo) in Ontario. Many potential disease-causing agents, amplified by anthropogenic actions, pose a threat to the health of
wildlife. Since their reintroduction in 1984, wild turkeys have increased in number and geographic range. Furthermore, these populations geographically overlap with domestic turkey farms (
wildlife-livestock
interface), and possible pathogen transmission between wild and domestic turkeys is a concern, as they are susceptible to infection with many of the same pathogens. Despite this, information on the health and the occurrence of pathogens that may cause disease in wild turkeys in Ontario is lacking. To address these knowledge gaps, I conducted a retrospective analysis of post-mortem findings and diagnoses for 56 wild turkeys submitted, over a 20-year period, to the Canadian
Wildlife Health Cooperative for diagnostic evaluation. Non-infectious diagnoses were more common than infectious, with emaciation identified most frequently. Next, a prospective study was conducted to investigate pathogens previously associated with disease outbreaks or decreased fitness of wild and domestic turkeys. Hunter-harvested and other opportunistically collected wild turkeys (n=215) from across southern Ontario were tested for Mycoplasma spp., Salmonella spp., Escherichia coli, Ornithobacterium rhinotracheale, Erysipelothrix rhusiopathiae, Pasteurella multocida, Campylobacter spp., Eimeria spp., avian pox virus, avian influenza viruses, and lymphoproliferative disease virus. Positive E. coli isolates were further tested for antimicrobial resistance (AMR). Laboratory methods included culture, fecal floatation, histopathology, and PCR. Most wild turkeys tested positive for Mycoplasma and Eimeria spp., and over half were positive for E. coli and lymphoproliferative disease virus. There were rare isolations of avian poxvirus and Campylobacter jejuni, and no detection of avian influenza viruses, Salmonella, O. rhinotracheale, E. rhusiopathiae, and P. multocida. Finally, AMR testing performed on Escherichia coli isolates documented limited resistance to antimicrobials. The baseline data provided by this research provides insight into the health of hunter-harvested wild turkeys in Ontario and will aid in future monitoring of disease emergence. In addition, it will contribute to conservation and management strategies that help to ensure sustainable populations of wild turkeys in Ontario.

▼ Freshwater mussels are considered to be the most
imperiled group of animals in North America, yet the environmental
factors that influence mussel assemblage structure are not fully
resolved. The life cycle of mussels suggests that dispersal of
mussels is linked to fish movement whereas growth and reproduction
might be expected to be controlled by broad-scale environmental
processes. A more thorough understanding of the responses of linked
lotic mussel-fish assemblages to scale-dependent environmental
characteristics is expected to improve both current ecological
understanding as well as inform conservation and management. My
research investigated the relationships between (1) stream
hydrogeomorphology and mussel and darter assemblages and (2) the
relative influences of local- and catchment (i.e., landscape)
-scale environmental factors on mussel assemblages in Big Darby
Creek, OH. In 2011 and 2012, I surveyed mussel and fish assemblages
and conducted geomorphic surveys at twenty study reaches
distributed in Big Darby Creek. I also collected environmental data
at local- (i.e., riparian land cover, stream hydrogeomorphic
characteristics) and catchment- (i.e., drainage area; catchment
land cover; modeled overland flow, sediment, and nutrient dynamics)
scales. For the first objective, principal component analyses and
stepwise multiple linear regressions were used to explore potential
relationships between hydrogeomorphic variables and mussel and fish
descriptors of the following assemblages: fish, darter, mussel, and
mussels known to use darters as hosts. For the second objective, I
used a partial constrained ordination approach to partition
variation in the mussel assemblage dataset among fish, spatial,
environmental, and shared (spatially-structured fish and
environmental) factors. At a coarse geomorphic resolution, density
of the overall fish assemblage as well as the darter component of
the fish assemblage (p = 0.048, p = 0.024; respectively) was
greater at geomorphically adjusting reaches, whereas fish species
richness was 1.2 times greater at equilibrium reaches (p = 0.047).
At a finer geomorphic resolution, eleven models emerged as
significant. Across all models, hydrogeomorphic parameters
explained from 20% (darter assemblage evenness) to 55% (density of
mussels using darters as hosts) of the variation observed in mussel
and fish assemblages. Drainage area was significant in almost every
model. Other important variables included embeddedness, velocity,
shear stress, roughness, channel dimensions, and sediment size.I
found that collectively, environmental, spatial, and fish datasets
explained 99.2% of the variation observed in mussel assemblage
structure. The shared component was the dominant predictor
variable, explaining 40.1% of mussel assemblage variation, whereas
fish density only accounted for 1.5%. The pure environmental
component accounted for 31.5% of the variation, split relatively
equally between local- (26.3%) and catchment- (32.4%) scale
influences. Overall, my results suggest that local-scale…

▼ Finally the loss of income farmers experienced in both
the ZR and the MSA during simultaneous FMD
outbreaks in the year
2012 was quantified, as well as the impact it had on livelihoods in
the ZR. A
commodity‐based trade approach may have reduced the
impact on farmers’ income significantly.
However, we farmers are
unable to comply with the proposed requirements for mitigating risk
and
ensuring food safety and quality in such communal systems in
the absence of interventions to build the
necessary capacity and
awareness. It is recommended that at the wildlife‐livestock
interface such as
those investigated in this study, an integrated
value chain approach to trade could serve as a catalyst
to
incentivise and enable farmer participation in holistic, integrated
rangeland and livestock
management practises that will promote
conservation and rural development.

▼ Surveillance for
wildlife diseases is critical to our
understanding of the emergence, transmission, persistence and
control of infectious diseases at the
interface of humans, domestic
animals, and
wildlife populations. Neospora caninum is a protozoan
parasite capable of infecting a wide range of canid and ungulate
species. The importance of the disease relates to economic losses,
mainly derived from endemic or epidemic abortions in cattle. In the
United States, coyotes and dogs are believed to be the main
definitive hosts and white-tailed deer and cows are the main
intermediate hosts. Our overall aim was to better understand the
wildlife-livestock
interface of N. caninum in natural settings.
First, we estimated the true prevalence of N. caninum in three
ruminant species by using Bayesian inference. We identified and
discussed differences between apparent and true prevalence (TP).
Differences in TP for some species suggest differences in the
epidemiology of N. caninum for these co-located populations.
Second, we evaluated the environmental phase of N. caninum shed in
wild canid scats. Results suggested that the role of this
environmental phase in the transmission to ruminants is likely
minor. Finally, we evaluated the role of host species heterogeneity
in the epidemiology of N. caninum circulating in a community. We
identified differences in the patterns of immunity, age structure,
and maternal and/or fetal antibody duration in three intermediate
(ruminant) host species. Also, we estimated the species-specific
contributions to the persistence of this pathogen in a community.
This research was approached from the One Health perspective and
provided a better understanding of N. caninum dynamics at the
wildlife-livestock
interface in an ecosystem.

▼ This thesis is focuses on Campylobacter carriage in mammalian
wildlife and livestock in southern Ontario. Multi-level logistic regression models were constructed to investigate Campylobacter spp. and antimicrobial resistant Campylobacter spp. carriage in
wildlife and livestock species on 25 farms. Samples were collected from dairy and beef cattle, swine and raccoons as well as a selection of other mammalian
wildlife. Molecular subtyping data, produced by the Campylobacter–specific 40-gene comparative genomic fingerprinting assay (CGF40), were used to compare isolates from
wildlife and livestock. Cluster analysis was conducted to visualize the groupings of
wildlife and livestock C. jejuni isolates found.
Wildlife and livestock carried Campylobacter at significantly different prevalences, had different antibiograms, and rarely shared the same CGF40 subtypes. Dendrogram and correspondence analysis indicated that the subtypes of Campylobacter circulating in livestock and
wildlife populations were distinct. Combined, these results suggest that transmission between mammalian
wildlife, especially raccoons, and livestock is limited.

▼ The work presented here investigates a number of
important components in the
epidemiology of foot-and-mouth disease
(FMD) at the
wildlife-livestock
interface along the
Kruger
National Park (KNP) and its adjoining private and provincial nature
reserves (APNR).
This epidemiological setting is unique and
complex, mainly due to the presence of African
buffaloes (Syncerus
caffer) persistently infected with the Southern African Territories
(SAT)
strains of the FMD virus. Despite a great deal of
experimentation and field research, FMD
transmission from both
persistently- and acutely-infected buffaloes to cattle is still
poorly
understood, although it is accepted that the two species
have to be in close contact for it to
occur. And even then, ‘close
contact’ is ill-defined. Comparisons of three intensive study
sites in the FMD protection zone, comprising both communally-farmed
as well as smallholder
cattle rangelands, were conducted to better
understand this livestock system and determine
livestock
distribution patterns. This vast heterogeneous landscape of the FMD
protection
zone follows a latitudinal gradient of both human
density and rainfall (increasing from north
to south), which is
reflected in similar gradients in cattle densities, the number of
households
owning cattle, consumption patterns as well as herding
practice, whilst inversely associated
with cattle sales and calf
mortality rates. Distribution studies of the cattle in these study
sites
revealed a dry season dependence on water, and contraction
of home ranges around
preferred habitat during the warm wet
season. Herding, or the lack thereof, was evident in daily activity
budgets of these cattle. Interestingly, seasonal differences in
stray buffalo
dispersal patterns were the inverse of their
domestic counterparts, being condensed along
the fence line during
the dry season. Stray buffalo events mainly consisted of single
animals
or very small groups, predominated by adult bulls. Most of
these animals were destroyed
soon after straying from the FMD
infected zone, although some managed to move into areas
with
unvaccinated cattle, especially along major river courses. Swift
removal of stray
buffaloes from livestock areas is paramount,
since recent outbreaks all share the
characteristic of stray
buffaloes being reported roaming the outbreak-area over extended
periods (months) prior to an outbreak. Combining cattle and stray
buffalo habitat suitability
estimates revealed areas likely to
facilitate contact between these species, which was
mostly driven
by cattle dispersal into those condensed areas along the fence and
rivers more
suitable for stray buffaloes during the cool dry
season. This is also the season when acute
infection with FMD is
most likely in buffaloes. Yet, when adjusting cattle habitat
suitability to
incorporate their density, the concentration of
preferred habitat during the warm wet season
forms small pockets
of high cattle density, amplifying contact risk with stray
buffaloes in these
areas. Simulation of stray buffalo…

▼ Wildfires have become an increasingly important issue in central Texas as more people move to the wildland-urban
interface. Although mitigation can reduce the risk of damage from wildfire, not all homeowners choose to mitigate. Using the area surrounding the Balcones Canyonlands Preserve wildlands in Austin, Texas as a case study, this research examined the factors that lead to homeowners’ decisions to or not to mitigate for wildfires. In particular, this study examined the difference between behavioral intention and behavior relating to wildfire mitigation. In addition, this study investigated the spatial aspects of risk perception, behavioral intention, and behavior by testing the effects of proximity to wildlands and to a relatively recent wildfire in the area. Study methods included a mail survey of residents living in subdivisions adjacent to the Balcones Canyonlands Preserve wildlands, statistical analysis, and a GIS analysis of residential location in relation to survey responses. This study adopted a modified version of the Theory of Planned Behavior called the “reasoned action approach” as the conceptual framework to explain homeowners’ behaviors and intentions. Statistical analysis was performed on survey responses relating to the conceptual variables in the reasoned action approach. The Intention model indicated that Attitude was the most important variable (40.6 % of total variance) relating to Intention, followed by Subjective Norm (10.1%), and Behavioral Control (1.3%). Risk Perception and Residency explained an additional 2.2% of the total variance. The Behavior models indicated that only Intention and Subjective Norm were predictors for Mitigation Behavior 1 (keeping gutters and roof free of leaves, needles, and branches), only Intention and Behavioral Control were predictors for Mitigation Behavior 2 (keeping tree limbs pruned at least 10 feet from the roof), and only Intention was a predictor for Mitigation Behavior 3 (keeping dead vegetation cleared within 30 feet of the house). The models explained 52.4% of the variance in performance of Mitigation Behavior 1, 38.9% in Mitigation Behavior 2, and 42.2% in Mitigation Behavior 3. The models were better at predicting respondents who did perform mitigation behaviors compared with those who did not. Distance was added to the models to test proximity effects, but this did not improve the predictive power of the models. Visual and hotspot analysis was performed to examine the relationships between proximity and risk perception, proximity and behavioral intention, and proximity and mitigation behavior. Overall, the visual and hot spot analyses did not detect any strong spatial patterns.

▼ Living in an expanding industrialized society requires the creation and maintenance of functional roadways that meet the needs of a mobile population. Roads are essential for commuters to travel to their desired destinations, yet they may be constructed anywhere and everywhere without sufficient thought about possible consequences to the surrounding environment. As vehicles travel on current roadways, they may be killing surrounding wildlife on a daily basis. This destruction of wildlife, known as road kill, is an increasingly common problem that must be addressed. Urban dwellers need to know that the surrounding animal environment is an important consideration when roads are constructed or improved.
The overall goal of this project was to assist in creating a repository of data related to road kill. Researchers could gather information and formulate findings from the database through web-based data mining tools that are implemented now and in the future for the project. Development planners could then present their findings to minimize the negative impact of urban development upon wildlife and humans.
The implementation goal of this project was to design and develop a functional mobile application that could conduct transect observations using a Global Positioning System. Another aspect of this undertaking was to permit crowd-sourcing road kill information through an i Phone device that utilizes an Application Program Interface for reporting observations to a remote database.
