prevalence of anti-toxoplasma gondii and anti-neospora caninum antibodies in goats slaughtered in the public slaughterhouse of patos city, paraíba state, northeast region of brazil.	the prevalence of anti-toxoplasma gondii and anti-neospora caninum antibodies was investigated in goats slaughtered in the public slaughterhouse of patos, state of paraíba, northeast region of brazil, and possible associations between sex of the animals and antibody prevalence were verified. three-hundred six blood samples from goats collected before slaughter by jugular venopuncture were used. for the serologic diagnosis of t. gondii and n. caninum, the indirect fluorescent-antibody test (ifat) ...	2007	17706359
seroprevalence of caprine arthritis-encephalitis virus in goats in the cariri region, paraiba state, brazil.	the seroprevalence of caprine arthritis-encephalitis virus (caev) in the cariri region of paraíba state, brazil, was determined in 60 goat herds using the agar gel immunodiffusion test. the overall seroprevalence was 8.2%, with seropositivity in 21/60 (35%) herds and 13/15 (86.6%) municipalities. bucks had a significantly higher frequency of infection (28.3%) than does (5.9%), and bucks that originated in other states had a significantly higher frequency of infection (76.5%) than those from para ...	2009	18675568
infection by trypanosoma vivax in goats and sheep in the brazilian semiarid region: from acute disease outbreak to chronic cryptic infection.	a study was undertaken to investigate the role of trypanosoma vivax in sheep and goat mortality and abortions in the brazilian semiarid region, where outbreaks had been previously reported in bovines. for this purpose, 177 goats and 248 sheep (20% of herds) were randomly sampled on four farms in the state of paraiba in may and october 2008. the animals were screened for trypanosomes by the buffy coat technique (bct) and pcr. infected animals, approximately 25% in both surveys, manifested apathy, ...	2009	19665308
