Abstract
Aim:
This cross-sectional survey was conducted to detect
anti- N. caninum antibodies in bovine dams' sera
samples in nine States of the Sudan.
Materials
and Methods: Two hundred and seventy six bovine
dams' sera samples collected from nine States in the
Sudan were screened for anti-Neospora caninum
antibodies using a commercial competitive ELISA (cELISA)
kits.
Results: The results showed an overall
prevalence rate of 15.9% (range 6.7% - 70%) of
Neospora caninum antibodies. The prevalence rates
were high in White Nile (70%) and North Kordofan
(30%), moderate in the Northern (15.6%), Red Sea
(13.3%) States and was low in the South Kordofan
(9.4%) and River Nile (6.7%). States with high
values of percentage inhibition (PI) detected in
White Nile State compared to other States. No
antibodies were detected in El Gadarif, Kassala and
South Darfur States. The prevalence was observed to
be high in crossbred dams (70%) with statistically
significant difference (P<0.05) compared to local
ecotype (9.3%). However, no correlation was observed
between infection rates in two age groups.
Conclusion: Neosporosis is prevalent in cattle
in most States of Sudan. Absence of evidence of
infection in three of the States investigated may
reflect the small number of herds and sera tested.
