Epidemiology of Cryptosporidium sp. infection among free-range and intensive farm birds in Akure South LGA, Ondo State, Nigeria

Abstract

Abstract Background Cryptosporidium spp. is an intracellular zoonotic protozoan parasite that causes cryptosporidiosis, a diarrhoeal disease of humans and domestic animals. Transmission of Cryptosporidiosis to humans and other animals is by ingestion of oocysts of the parasite and as low as ten oocysts can cause clinical infections in otherwise healthy persons. The aim of this study is to investigate the prevalence of Cryptosporidiosis and compare the rate of infection between free range bird and poultry bird reared in Akure South LGA, Ondo State, Nigeria. Result The overall prevalence of Cryptosporidium reported in this study was 11.9%. Free-range birds show a higher prevalence rate 13.2% of Cryptosporidium oocysts than 10.9% in poultry birds. Aule recorded the highest prevalence of Cryptosporidium oocysts infection (16.1%) followed by Ipinsa (12.2%), Onigari (10%), and FUTA (8.1%). The highest prevalence 15.9% was recorded in broilers, while turkey showed no infection (0%) by Cryptosporidium. Semi-intensive system of farming was showed to be more susceptible to Cryptosporidium oocysts infection at 13.3% followed by the 12.6%, 10.3% in deep litter and battery cage. The female birds recorded higher Cryptosporidium oocysts infection (12.2%) than the male (11.6%). Conclusion The study established the presence of Cryptosporidium oocysts infection among studied birds in Akure South LG of Ondo State, Nigeria.
