OCCURRENCE AND RISK FACTORS ASSOCIATED WITH FAECAL SHEDDING OF CRYPTOSPORIDIUM OOCYSTSIN AVIAN SPECIES IN KANO METROPOLIS, NIGERIA
Abstract:
Cryptosporidium is a coccidian parasite found infecting a wide range of mammals including man, birds and lower vertebrates. The aim of this study was to determine the occurrence and risk factors associated with faecal shedding of Cryptosporidium oocysts in avian species in Kano Metropolis, Nigeria. Faecal samples from three hundred and thirty avian species were examined for Cryptosporidium oocysts using Modified Ziehl Neelsen staining technique. The overall prevalence was 6.4%. Live bird markets had the highest prevalence rate of 10%, slaughter slabs and commercial farms had 4.55% and 4.55% respectively. The difference in the prevalence rates between sampling points was not significant (P>0.05). Based on species, turkeys had the highest prevalence rate of 18.75%, followed by ducks (9.09%), chickens (6.61%), guinea fowls(0%) and pigeons(0.0%).The prevalence of Cryptosporidiumamong the different avian species was not significant (P>0.05). The occurrence of Cryptosporidium oocysts in avian species based on Local Government Areas (LGAs) were also studied. Flocks in Dala LGA recorded the highest prevalence rate of 12.12%, while those in Kumbotso had the lowest prevalence of 1.52%. The association between Cryptosporidium oocysts and LGAs was not significant (P>0.05). Risk factors for the spread of Cryptosporidium oocysts by avian species were also studied and analyzed; source of birds (interstate OR=1.314; p=0.735), frequency of cleaning (not daily OR=1.859; p=6.756), source of feeds (not commercial OR= 2.604; p=0.126), source of water (well water OR=1.770; p=0.521) and types of cage (wooden cage OR=1.186, p=0.533) were found to have a high risk estimate for the spread of the Cryptosporidium, though not significant (p>0.05). This study has shown the presence of Cryptosporidium oocysts in poultry sampled in Kano Metropolis, Nigeria, which is of veterinary and public health significance. It is therefore imperative that public awareness should be embarked upon vii on the importance of biosecurity, so that the veterinary and public health significance of the disease can be prevented.
