ABSTRACT
Ansari-Lari M, Motlaghb SA, Moravvejib M, Bahramib S,
Hosseini A., Seroepidemiological study of Neospora caninum in dairy cattle,
Onl J Vet Res, 15 (2): 155-161, 2011. Prevalence of Neospora caninum
in dairy cattle herds in Shiraz, Iran is reported. Related risk factors for
N. caninum infection and association with abortion
was investigated. Thirty two herds were used and blood was taken from ~10% of
each herd. Sera (169) was tested for N. caninum by
ELISA. History of abortions, dogs or wild carnivores feeding off
aborted offal was recorded. Individual prevalence was 58% and herd 78%. Thirty
percent of herds had had recent abortions and 8.7% recurrent ones. We found no
correlation between N. caninum, abortion or
dogs. We did find that abortion and wild carnivores with access to aborted
offal was a significant factor (P=0.006). Our results suggested that seroprevalence of N. caninum
in these herds was relatively high but is not a significant reproduction
problem in the region. Prospective cohort studies are needed to evaluate the
definite role of N caninum.
