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.

“…Several authors have used serological tests to demonstrate an increased risk of abortion amongst Neospora caninum positive cows. They observed that seropositive cows are more likely to abort than seronegative ones (Dubey et al 2007;García-Vázquez et al 2005;González-Warleta et al 2008;López-Gatius et al 2004).…”

Epidemiology and Control of Neosporosis andNeospora caninum

SUMMARY Neospora caninum is a protozoan parasite of animals. Until 1988, it was misidentified as Toxoplasma gondii. Since its first recognition in dogs in 1984 and the description of the new genus and species Neospora caninum in 1988, neosporosis has emerged as a serious disease of cattle and dogs worldwide. Abortions and neonatal mortality are a major problem in livestock operations, and neosporosis is a major cause of abortion in cattle. Although antibodies to N. caninum have been reported, the parasite has not been detected in human tissues. Thus, the zoonotic potential is uncertain. This review is focused mainly on the epidemiology and control of neosporosis in cattle, but worldwide seroprevalences of N. caninum in animals and humans are tabulated. The role of wildlife in the life cycle of N. caninum and strategies for the control of neosporosis in cattle are discussed.

RESUMENEl objetivo del estudio fue determinar la seroprevalencia de neosporosis en ganado bovino llevado a una feria ganadera en la Región de La Araucanía, Chile. Se muestrearon 437 vacas y vaquillas procedentes de predios ganaderos de comunas cercanas. Las muestras de suero fueron analizadas mediante la técnica ELISA indirecta para detectar anticuerpos contra Neospora caninum. El 21.1% (92/437) de las muestras resultaron positivas a N. caninum, mientras que 13.9% (61/437) resultó sospechoso y 65.0% (284/437) resultó negativo Los resultados obtenidos indican que la infección se encuentra diseminada en los predios y comunas de la región.Palabras clave: Neospora caninum; bovino; aborto; seroprevalencia ABSTRACTThe aim of the study was to determine the seroprevalence of neosporosis in cattle in a livestock fair in the Region of La Araucanía, Chile. Blood samples were collected in 437 cows and heifers belonging to nearby farms. Serum samples were analyzed by the indirect ELISA technique to detect antibodies against Neospora caninum. The results showed that 21.1% of the animals were positive to neosporosis, while 13.9% (61/437) was uncertain and 65.0% (284/437) was negative. The results indicate that the infection is spread in the farms of the region.
