The aim of this study was to determine the seroprevalence of Neospora caninum antibodies and its effects on reproductive parameters in cows in intensive dairy herds in Dakar. Randomised blood samples
were taken for serology from 196 cows in four herds with a history of sporadic abortion. All of the sera were assayed for
antibodies against N. caninum, Candida guillermondii, Coxiella burnetii, and Chlamydophila sp. The associations between serostatus and reproductive parameters (abortion, number of inseminations to conception, and
calving to conception interval) were assessed over a period of 5 years (2004–2008). The seroprevalence of N. caninum antibodies in dairy cattle was 17.9%. The local Gobra breed and crossbreeds had higher levels of N. caninum antibodies than exotic breeds (p < 0.05). For the most recent pregnancies, seropositive cows required more inseminations to establish conception than seronegative
cows (p < 0.05). The results indicate that dairy cattle from Dakar are exposed to N. caninum. Neosporosis should, therefore, be systematically considered as a cause when the calving to conception interval is prolonged. 相似文献

A survey of gastrointestinal helminths of the common helmet guinea fowl (Numida meleagris galeata) in Burkina Faso 总被引:1,自引:0,他引:1
Guinea fowls in Burkina Faso (Africa) harbored 13 species of helminth parasites. The two most abundant species were Subulura suctoria and Ascaridia numidae, which comprised 89% of the nematodes. The other nematode species (Gongylonema congolense, Eucoleus annulatus, Synhimantus spiralis, Tetrameres fissispina, and Cyrnea parroti) occurred at low levels. Five species of cestodes and one acanthocephalan were also present. It is likely that guinea fowl act as important reservoir hosts of chicken nematodes. 相似文献
