▼ Leptospirosis is a worldwide veterinary and public health concern, and emerging infectious disease of horses. The spirochete can be directly transmitted by contaminated urine, placental fluids, semen, infected tissues, reservoir hosts, or flood waters. Seroprevalence and infecting serovar vary with geography, yet diagnosis using the gold standard microscopic agglutination test (MAT) merely confirms a high exposure rate. Subclinical infection can complicate diagnosis. The aims of this study were to use semi-nested PCR on urine from apparently healthy horses to determine period prevalence of leptospiral shedding and to correlate these findings with MAT results to establish associations with client based survey data regarding horse management and environment. Serum and free-catch urine were collected from 204 healthy horses between May 2016- December 2017. Serum was used to determine GGT, creatinine concentrations, and six serovar MAT (Canicola, Hardjo, Icterhemorrhaegiae, Pomona, Grippotyphosa, Bratislava). Urine samples were submitted for PCR testing of leptospiral 23S rRNA. Client consent and survey data were collected for all subjects. Potential risk factors included drinking water source, exposure to livestock and dogs, geographical location, season, and precipitation. Two horses were positive on urine PCR for leptospirosis (shedding prevalence 1%), yet only one had a high reciprocal MAT titer of ≥800. Both horses were negative on urine PCR one month later without treatment. Approximately 77% of horses (157/204) were seroreactive (MAT reciprocal titer ≥100) for at least one serogroup, and Bratislava was detected more frequently than others (47.5%; (97/204)). Apparently healthy horses infrequently shed Leptospira spp. in urine, yet seroreactivity in clinically normal horses is high (77%), confirming high exposure rates to Leptospira spp. in the Central Midwest. Further studies should target serovar specific PCR tests and incorporate PCR testing in horses clinically affected with leptospirosis. Advisors/Committee Members: Elizabeth Davis.

▼ The studies presented in this thesis investigate key questions about leptospirosis diagnostics in animals and humans in New Zealand (NZ): how do different diagnostic tests perform on various specimens collected at different stages of infection; how well do tests from a commercial and a research laboratory agree; how do serological test results and urine/kidney quantitative real-time PCR (qPCR) results compare; and what is the utility of PCRs on blood from acute human cases? Additional studies investigate occupational risk at the human-animal interface. In trials where the animals were challenged with Leptospira borgpetersenii serovar Hardjobovis (Hardjobovis) and/or Leptospira interrogans serovar Pomona (Pomona), sequential samples were taken from sheep and cattle to evaluate diagnostic tests at various known times post-infection. Although no statistically significant differences were found, results suggested that during the early stage of a Pomona infection in sheep, qPCR on serum had the highest sensitivity for detecting leptospires in blood, followed by blood culture and qPCR on whole blood. In sheep infected under carefully controlled experimental conditions, culture tended to have higher sensitivity for detecting leptospires (either Hardjobovis or Pomona) in urine than qPCR; whereas in cattle with Hardjobovis infection, higher sensitivity was apparent using qPCR. Sensitivity was similar in culture and qPCR for detecting leptospires in kidney from sheep with either Hardjobovis or Pomona infections. There was low sensitivity and specificity of dark field microscopy for both urine and kidney samples, thus questioning the usefulness of this technique in veterinary settings. A cross-sectional study was carried out at a NZ sheep and cattle abattoir to investigate the seroprevalence (by microscopic agglutination test (MAT)), shedding rate (by urine qPCR), and renal colonisation rate (by kidney qPCR) of slaughtered animals. Urine, kidney and blood samples were collected from carcasses of 399 sheep and 146 cattle. The animal-level seroprevalence found in sheep (57%, predominately lambs) and cattle (73%, predominately ≤18 months old) was substantially higher than in previous studies; these and the recorded shedding rate (27%) and renal colonisation rate (27%) raised occupational health concerns that meat workers from this abattoir may be at risk of exposure to leptospires during their daily work routine. iv Samples from this abattoir study were used to investigate the inter-laboratory test agreements between a research (HLRL) and a commercial veterinary diagnostic laboratory (GV), and test agreements (HLRL) between specimens for leptospirosis diagnosis. Urine qPCR results on from the two laboratories had almost perfect agreement (kappa = 0.93). The MAT agreement between these two laboratories was higher for Hardjobovis (kappa = 0.94) than Pomona (kappa = 0.53). This serovar-dependent difference suggested that the different MAT results may be more likely due to the different source of antigen cultures (especially…

Leptospirosis is a spirochetal zoonosis of worldwide distribution. It is caused by the pathogenic members of the genus Leptospira that includes more than 250 different serovars, whose distribution may be restricted geographically. Despite the high antigenicity of surface lipopolysaccharide molecules, they afford little cross-protection against infectivity by other serovars. In addition, an economic and easy-to do specific diagnostic test is necessary for early diagnosis. Thus candidate antigens are to be identified both for diagnosis and vaccine purposes. This can be achieved by a better understanding of host-pathogen interactions. Acquisition of iron is one of the important factors contributing to the successful establishment of the pathogen, as the amount of available iron is limiting in the mammalian host. Though the requirement of iron byLeptospira sp. is known, there are no reports on the mechanism of iron acquisition. Earlier studies in our lab showed for the first time that pathogenic leptospires acquire iron directly via a hemin receptor. Siderophores could not be detected in the spent growth medium. Using a bioinformatics approach, a TonB-dependent outer membrane protein (LB191) was identified in Leptospira interrogans serovar Lai using the Fe3+-enterochelin receptor FepA of Escherichia coli. The protein, referred to as HbpA showed a similar fold as other Fe3+-siderophore receptors upon homology modeling. Wet lab experiments with recombinant HbpA confirmed it to be a hemin receptor. In this study, after several trials with different chelators, we established conditions of iron-deprivation for the growth of Leptospira spp. with EDDA at 200 µM final concentration, with a final incubation at 37ºC for 5½ h. We detected HbpA as an 81 kDa protein in low-iron organisms of L. interrogans serovar Lai that was not expressed in high-iron conditions. Analysis of several leptospiral species showed that HbpA was restricted to serovars belonging to L. interrogans. Immunofluorescence studies using anti-HbpA antibodies..

▼ Leptospirosis, a zoonotic disease, is transferable through wild animals to other animals and humans directly and indirectly through contact with urine on mucous membranes. This disease can pose hazards for humans because of their increased contact with wild animals through increased urbanization and greater wildlife rehabilitation efforts and also through increased contact with domesticated animals. Furthermore, humans also have the potential of contracting this potentially fatal disease through recreational activities in contaminated waters or soils. The disease can present itself mildly, similar to symptoms of the flu, or more severely, leading to end-organ damage of multiple systems. Having been reinstated as a nationally notifiable disease by the Centers for Disease Control and Prevention in January 2013, leptospirosis has been recognized as a re-emerging zoonosis that has global public health implications. Understanding the disease is important in limiting its transmission; thus, this thesis aims to provide a review of the biology and transmission of leptospirosis to animals and humans, providing a basis in understanding the possible ways to limit the transmission and prevent future outbreaks. Furthermore, this thesis describes the manifestations, diagnostic testing, and treatment options for leptospirosis in canines and humans, as the increased prevalence of canines in households may pose a risk to humans in the future in the transmission of leptospirosis. According to current research, leptospires are extremely viable bacteria that can survive for long periods of time in a variety of environments and host species. Researchers have conducted various experiments to evaluate the factors that increase the virulence of leptospires. Experiments include the osmolarity, presence of serum, temperature chances, and the presence of iron. Results demonstrate that virulence increases with increased osmolarity, presence of serum, increased temperature, and the presence of iron. These characteristics of pathogenic leptospires allow them to avoid destruction by the immune system and colonize in the host, specifically in the renal tubules, allowing for excretion into the environment. Limiting the transmission of the disease is very important to prevent future outbreaks for animal species and humans. One method of limiting this transmission includes the use of vaccines. A major issue is the transmission of disease surround renal shedding, or excretion of the bacteria in urine. Canine polyvalent vaccines, containing multiple serovars, have been proven to be effective for a year, providing immunity and decreasing renal shedding of the bacteria. While vaccines for humans have been developed, they are not widely used due to the variation of serovars that are able to infect humans around the world and also the geographic distribution of disease, with prevalence mainly in tropical regions. Since leptospirosis is a disease that is not well-known, but can be found globally, there is necessity for greater emphasis on…

A longitudinal ‘abattoir study’, in which blood from workers (n=592) from sheep (n=4), deer (n=2) and beef (n=2) slaughtering abattoirs was tested by the microscopic agglutination test (MAT), revealed that 10-31%, 17-19% and 5% of workers respectively, had antibodies against Leptospira interrogans sv Pomona (Pomona) and/or L. borgpetersenii sv Hardjobovis (Hardjobovis). While the annual infection risk for meat workers of sheep plants was 11.1%, it was 0% in workers processing deer and 1.2% in those processing beef cattle. Sixty workers had a history of probable leptospirosis while working in abattoirs between 1962 and 2010 and three sheep abattoir workers within the one year study period. In sheep abattoirs, new infection with Hardjobovis or Pomona measured by serology was associated with a two-fold higher risk of ‘flu-like’ illness, and an average of four days absence from work. The average annual risk of experiencing flu-like symptoms due to infection with Leptospira measured by serology was 2.7%. The under-ascertainment of officially notified cases with leptospirosis in the last five years was estimated at between 16 and 56 times. Work position was the strongest risk factor for sero-positivity with Pomona and/or Hardjobovis in sheep and deer abattoir workers. The prevalence and new infection risk was highest in workers at the beginning of the slaughter board and the use of personal protective equipment (PPE) appeared not to reduce the risk of sero-positivity or new infection. The risk factor analysis revealed that the infection risk prevailed in the abattoirs and was not evident for non-work related risk factors, such as hunting, home slaughtering and farming. In a multi-species cross-sectional ‘farm study’ (n=238), 97% of sheep and beef and 76% of deer farms had at least one in 20 animals MAT sero-positive against Hardjobovis and/or Pomona. Overall, 50% of adult sheep, 58% of adult beef and 34% of yearling/adult deer were positive against either serovar. Hardjobovis was more prevalent in all three livestock species than Pomona. The regional prevalence distribution in sheep was different for Hardjobovis and Pomona. Grazing beef with deer reduced the likelihood of positivity against Pomona in beef. Co-grazing with another species did not increase the odds of the within-herd prevalence for deer and sheep of Pomona or Hardjobovis and for beef the within-herd prevalence of Hardjobovis controlling for other farm-level risk factors. The incidence of probable leptospirosis in cattle herds in 2009 was 2.6%, in sheep flocks 0% and in deer herds 1%. Tailing rates of sheep farms were positively correlated with prevalence of Hardjobovis: a 1% increase in prevalence was equivalent to a 0.11 increase in tailing percentages, which is unlikely to be causative since this association lacks biological plausibility. All other reproduction and culling rates of any species were not significantly associated with…
