1. Barros Lama, Macarena. Epidemiologic evaluation for Toxoplasma gondii, parvovirus, distemper virus and leptospira in domestics pets, American mink (Neovison vison) and Souther river otter (Lontra provocax) in Southern Chile .

Degree: 2017, Universidad Andrés Bello

The increase in human population and domestic pets, such as dogs and cats, and introduction of species, such as American mink are generating important consequences in terms of habitat loss and pathogen pollution of ecosystems with potential to generate negative impacts in biodiversity. For this, it is essential to perform studies that illustrate the sanitary situation of Chilean native species, particularly those with serious conservation problems, like Southern river otter, to be able to understand and predict how infectious agents spread, and whether they represent a risk for the conservation of these wild species. In particular, this investigation seeks to carry out epidemiologic evaluation of four important infectious agents: Toxoplasma gondii is the etiological agent of zoonotic disease toxoplasmosis, and is associated to cat abundance and anthropogenic disturbance. The present study analyzed seroprevalence (modified agglutination test, MAT, cut-off 1:25) and presence of T. gondii DNA in American mink, Southern river otters and domestic cats in Southern Chile. Mean seroprevalence of T. gondii was 64% of 151 total animals sampled: 59% of 73 American mink, 77% of 13 Southern river otters, 68% of 65 domestic cats. Toxoplasma gondii DNA was detected in tissues from one American mink and one Southern river otter. The present study confirms the widespread distribution of T. gondii in Southern Chile, and shows a high exposure of semiaquatic mustelids and domestic cats to the parasite. Cats and anthropogenic disturbance have a role in the maintenance of T. gondii infection in ecosystems of southern Chile. 8 Parvovirus and canine distemper virus are important agents that can infect carnivores, which causes severe disease in Canidae and Mustelidae. Domestic dogs are considered a problem for public health and for conservation of endangered species, because it can transmit infections to wildlife, such as parvovirus and canine distemper virus. This study analyzed, by PCR the presence of Canine Parvovirus (CPV) and Canine Distemper Virus (CDV) in domestic dogs (n=82), American mink (n=48) and native Southern river otter (13) in the Chilean Patagonia. One dog and two minks were found positive to CPV, these samples were confirmed as CPV by sequencing; but which showed 100% identity with CPV, Feline Panleukopenia and mink Enteritis virus. Non CDV was found. Leptospirosis is an important zoonosis with worldwide distribution caused by pathogenic bacteria of the genus Leptospira. The North American mink has an important role in the environmental contamination with Leptospira, as minks live in aquatic environments and are the predators of rodents. Blood and kidney samples were obtained from 57 minks in southern Chile 39ºS to 45ºS. Pathogenic species of Leptospira were detected by PCR on 31/57 minks. To determine the species we sequenced the 16S rRNA gene on nine of the positive samples. We predicted two pathogenic species: L. interrogans (five samples) and L. borgpetersenii (four samples).… Advisors/Committee Members: Medina-Vogel, Gonzalo (advisor).

2. Poo-Muñoz, Daniela Alejandra. Where wilderness and humans meet : assessing interactions between people and wild and domestic carnivores in a fragmented landscape .

Degree: 2015, Universidad Andrés Bello

Urban sprawl and human activities are increasingly occupying and disturbing natural ecosystems, replacing pre-existing natural areas with a hostile matrix composed of human settlements, domestic animals, forest plantations, and agriculture, among others. These changes are fragmenting natural landscapes, with remaining natural areas surrounded by an anthropogenic matrix. This scenario increases interactions between humans, domestic animals, and wildlife , triggering conflicts mediated principally by resource competition . Additionally, domestic animals that accompany humans, such as domestic dogs, can actas an "extension" of human activities inside natural areas, with detrimental effects on wildlife. Domestic animals can also actas a bridge, translocating micro and macroparasites between natural areas and the anthropogenic matrix. This research aimed to determine the effects of an anthropogenic matrix on wild carnivores from a natural reserve, in terms of interactions between humans, domestic animals, wildlife, and their ectoparasites. The study was developed in the interface area between a natural reserve (NR) and the surrounding anthropogenic matrix (MA). To accomplish this aim, we developed three objectives, the first objective (Chapter 1), aimed to determine factors associated with people's recognition and attitudes towards wildlife and native carnivores (chilla fox, culpeo fox, and lesser grison), through interviews with local inhabitants. The second objective (Chapter 11), was to determine the factors influencing dogs' presence inside the NR and the effective protection of a Natural Reserve (NR), in terms of edge effects, and was based on dog's presence and movements. To achieve this goal, we developed a camera- trap survey and domestic dog fine-scale tracking through data loggers. The third objective (Chapter 111) was to characterize ectoparasitic species and Rickettsia spp. from domestic and wild carnivores collected in the NR and surrounding human settlements. We use morphological identification and molecular analysis to achieve this goal. Via interviews, we found that the species lesser grison was poorly recognized by inhabitants, with only 16% of people identifying the species. Additionally, personal attitudes towards wildlife and foxes were positively influenced by: higher education levels, closeness to the NR, and not having experiences with poultry predation/attacks. Nevertheless, for the lesser grison, negative attitudes were also reported. For this species, more negative attitudes were detected among the elderly, people that had encounters with lesser grison , and/or those who had poultry or experienced poultry predation/attacks. Models based on camera trap data detected that variables that best explained the presence of domestic dogs were the distance to houses and cattle presence, the latter a previously undescribed variable, that should be considered for dog management in rural areas. Camera trap data and dog movement confirmed that under a conservative approach,… Advisors/Committee Members: Medina-Vogel, Gonzalo (advisor).
