Prevalence, Intensity and Associated Factors of Cysticercus tenuicollis in Small Ruminants in the Northwest Region of Cameroon.
Background: Cysticercus tenuicollis infection, which can cause production and economic losses in livestock, is neglected in most African countries, including Cameroon.
Objective: To determine the prevalence, intensity and associated factors of C. tenuicollis in small ruminants in the Northwest region, Cameroon.
Materials and methods: A total of 1106 small ruminants (493 sheep; 613 goats) originating from divisions of the study region and destined for slaughter in Bamenda municipality were examined. Following slaughter, intensive meat inspections were performed to detect C. tenuicollis cysts based on standard procedures.
Results: Overall, the prevalence of C. tenuicollis was 34.36% (31.62%-37.21%), and no difference (χ2 = 1.43, p = 0.23) was observed between goats (35.89% [32.19%-39.76%]) and sheep (32.45% [28.47%-36.70%]). C. tenuicollis cyst was prevalent in all divisions in the region and detected during the entire study period. Weight, body condition score, pregnancy and lactating status of females, origin of the animals and season were the major (p < 0.05) factors in goats and only age (p < 0.05) in sheep. C. tenuicollis cysts were predominant in the abdominal cavity (97.90%) (OR = 2477.79; 889.45-6902.46; p < 0.0001, χ2 = 701.19) and mainly attached to the omentum (71.84%) (OR = 20.03; 13.53-29.66; p < 0.0001, χ2 = 269.13) compared to the pelvic cavity and other organs, respectively.
Conclusion: The study showed high prevalence and widespread distribution of C. tenuicollis infection in small ruminants and suggested that cysticercosis in small ruminants and its associated socio-economic implications for livestock production are neglected in Northwest Cameroon. Concerted veterinary-livestock farmer efforts, monitoring of infected small ruminant populations and regular parasite control in dogs in contact with small ruminants and prevention of contamination of pastures with T. hydatigena eggs by barring access of potential definitive hosts are essential for the control of the disease.
期刊介绍：
Veterinary Medicine and Science is the peer-reviewed journal for rapid dissemination of research in all areas of veterinary medicine and science. The journal aims to serve the research community by providing a vehicle for authors wishing to publish interesting and high quality work in both fundamental and clinical veterinary medicine and science.
Veterinary Medicine and Science publishes original research articles, systematic reviews, meta-analyses, and research methods papers, along with invited editorials and commentaries. Original research papers must report well-conducted research with conclusions supported by the data presented in the paper.
We aim to be a truly global forum for high-quality research in veterinary medicine and science, and believe that the best research should be published and made widely accessible as quickly as possible. Veterinary Medicine and Science publishes papers submitted directly to the journal and those referred from a select group of prestigious journals published by Wiley-Blackwell.
Veterinary Medicine and Science is a Wiley Open Access journal, one of a new series of peer-reviewed titles publishing quality research with speed and efficiency. For further information visit the Wiley Open Access website.
