Dissertação (Mestrado em Ciência Animal) - Universidade Federal de Goiás, Goiânia, 2018.http://repositorio.bc.ufg.br/tede/handle/tede/8279The prevalence of anti-Neospora caninum antibodies in cattle from Kalunga Historical Heritage and Cultural Heritage (SHPKC) herds and associated risk factors were evaluated. A total of 141 SHPCK properties were studied and 4,810 bovine serum samples and 47 Murrah buffalo samples were collected, totaling 4,857 cattle, including animals of different races, different age groups, and male and female. The enzyme-linked immunosorbent assay (ELISA) was used to identify seroreagent animals for antibodies anti-N. caninum. A questionnaire was applied to obtain information on socioeconomic and zootechnical data of the owners and to verify the risk factors associated with the occurrence of neosporosis. The prevalence of anti-N. caninum in animals from the SHPCK region was 8.3%, represented by 405 positive animals and 75.2% at the herd level. The following factors were associated with the occurrence of antibodies anti-N. caninum: annual temperature, maximum temperature on the hottest day of the month, coldest minimum temperature of the month, vaccination against foot-and-mouth disease, vaccination against clostridiosis, contact with wild animals, high precipitation and presence of wetlands.
