Item A comparative study of three methods for detecting Fasciola infections in Nigerian cattle(VETERINARSKIARHIV, 2008) Adedokun, O. A.; Ayinmode, A. B.; Fagbemi, B. O.Qualitative examination of Fasciola gigantica eggs in faeces and bile were compared with the detection of precipitating antibodies in sera by agar gel precipitation test (AGPT) in 1000 cattle slaughtered at the Bodija municipal abattoir in Ibadan, Nigeria. Faecal and bile examination methods detected (196) 33.5% and (389) 38.9% of the animals as positive for fasciolosis, while (474) 47.4% were positive by AGPT. Both direct bile examination and faecal egg detection methods have high specificity and positive predictive value (100%) when compared with AGPT. However, lower values for sensitivity and negative predictive value were observed for both faecal egg examination (66.5% and 67.9% respectively) and bile examination (81.0% and 78.9% respectively). Fecal and bile examination failed to detect 33.5% and 19.0% of the cases detected by AGPT. The results of this study revealed that the AGPT could become a better test for the herd diagnosis of bovine fasciolosis for veterinarians and other investigators in Nigeria.Item Seasonal prevalence of fasciola gigantica infection among the sexes in Nigerian Cattle(Medwell Journals, 2008) Adedokun, O. A.; Ayinmode, A. B.; Fagbemi, B. O.This study examined the seasonal prevalence of fasciolosis between tire sexes in Nigerian cattle. The possible role and effect of sex on prevalence of the disease is also discussed. One thousand cattle were examined for infection using the fecal and bile examination for Fasciola eggs and Agar gel precipitation test. Total 750 75%), 448 (44.8%) and 450 (45%) positive were detected by each of tire three methods respectively. The first peak of infection was detected in February' and the second from September to October. Prevalence was higher (52.3%) during the rainy seasons. The annual prevalence was higher in females (63.7%) than in males (36.3%). Prevalence was also higher in females from December to September and peaked (8.1%) in February. Peak prevalence for males occurred in September and October (6.6%), overall prevalence was found to be higher in the females and statistically significant during the dry season.
