ABSTRACT
Compared to cattle and sheep, the prevalence in goats is lower. Dynamics of antibodies in 13 pregnant goats were followed; titers fluctuated 4–8 fold. The prominent features of neosporosis-associated encephalitis in goats were glial nodules with numerous tissue cysts and the presence of few tachyzoites. The goat that had stillbirth had an indirect fluorescent antibody test titer of 1:100 on the day of mating, a titer of 1:3200 at the time of parturition, and at 3 months after parturition the titer declined to 1:400. Goats were bred and blood samples were obtained on 0, 30, 60, 90, and 120 days after mating, and 1, 2, and 3 months after parturition. Protozoal-associated lesions were found and properly described in brain, lung, kidney, and heart of abortions caused by N. caninum from Spain. Nubian goats developed antibodies from 2 weeks onwards, peaking 1:3200 and 1:6400 at 24 and 35 day post inoculation, respectively.
