Cryptosporidium and associated risk factors in local breeds of pigs kept in Donga Local Government Area Taraba State, Nigeria

Abstract

Cryptosporidium, an enteric protozoan parasite, poses economic losses in animal production and has zoonotic potential. This study aimed to determine the prevalence of cryptosporidium and associated risk factors in local pig breeds within Donga Local Government Area of Taraba State, Nigeria. A cross-sectional study was conducted, and a total of 384 faecal samples were collected from pigs in eight sampling sites. The samples were examined using the modified Ziehl-Neelsen staining technique.The results showed an overall prevalence of 27.9% (107/384) for cryptosporidium oocysts. The prevalence was significantly higher in pre-weaned piglets (64%) compared to post-weaned (26.9%) and adult pigs (24.14%). Female pigs had a significantly higher prevalence (49.21%) than males (17.4%), and diarrhoeic pigs had a significantly higher prevalence (55.2%) than non-diarrhoeic (22.9%). The prevalence was higher in the rainy season (42.4%) than in the dry season (10.3%).The detection of Cryptosporidium spp. oocysts in the faeces of pigs suggests that these animals may serve as potential reservoirs and shedders of this protozoan parasite, contaminating the environment and serving as a source of infection to other animals and humans. Adequate personal and environmental hygiene, along with prompt veterinary care, should be intensified.
