Abstract

BACKGROUND Bovine fascioliasis is a parasitic disease that affects cattle. It leads to direct and indirect great economic loss due to animal mortalities, growth retardation and expenditure on anthelmintics, reduction livestock productivity and essentially condemnation of infected liver by inspection service. The study was carried out to determine the seasonal prevalence and estimated financial losses of fascioliasis in cattle in the Western Highlands of Cameroon. METHODOLOGY A total of 2167 cattle were selected. Later, the cattle, have being the carcasses, were dissected, and the livers were dissected and carefully examined for adult liver flukes. Faeces were collected immediately after the cattle were killed and examined using the formol-ether concentration technique. Condemned livers were weighted to estimate the financial losses using the average price of a kilogram of liver. RESULTS A total 428 of cattle were found with infected livers or egg in the faeces giving a total prevalence of 19.75%. Among the infected carcass, 18.64% had both the Fasciola eggs in the faeces and flukes in the liver while 1.10% had only flukes in the liver. Results revealed that prevalence of Fasciola spp. was significantly higher during the rainy season (23.48%) than 16% in the dry season (p = 0.00). A significantly (p = 0.000) higher prevalence was also observed in females (33.9%) than in males (13.1%). Age range showed significant (p = 0.000) influence with the animals of 8-10 years old recorded the highest prevalence of 39.3%. Furthermore, 433.1 kg of liver was condemned giving a direct financial loss of 1221,550 FCFA (2049.64 USD) and an annual financial loss due to liver condemnation estimated to 1814,775 (3045.01 USD). CONCLUSION Findings of this study indicated that bovine fascioliasis is prevalent in cattle in the Western Highlands of Cameroon, and it leads to an important financial loss particularly in the rainy season.

喀麦隆西部高地巴门达和巴富萨姆屠宰场屠宰的牛群中牛法氏囊病的发病率和直接经济损失。

背景牛筋膜炎是一种影响牛群的寄生虫病。由于动物死亡、生长迟缓、抗蠕虫药支出、牲畜生产力下降以及检查部门对受感染肝脏的判定，该病导致了直接和间接的巨大经济损失。本研究旨在确定喀麦隆西部高地牛群中法氏囊病的季节性流行情况和估计的经济损失。随后，对牛的尸体进行解剖，剖开肝脏并仔细检查肝吸虫成虫。在牛被杀死后立即收集粪便，并使用甲醇-乙醚浓缩技术进行检查。结果共发现 428 头牛的肝脏或粪便中含有受感染的虫卵，总感染率为 19.75%。在受感染的胴体中，18.64%的牛粪便中既有法氏囊虫卵，肝脏中也有吸虫，1.10%的牛肝脏中只有吸虫。结果显示，雨季的法氏囊虫感染率（23.48%）明显高于旱季的 16%（p = 0.00）。女性的发病率（33.9%）也明显高于男性（13.1%）（p = 0.000）。年龄范围也有明显影响（p = 0.000），8-10 岁的动物发病率最高，为 39.3%。此外，433.1 千克肝脏被没收，直接经济损失为 1221,550 非洲金融共同体法郎（2049.64 美元），每年因肝脏被没收造成的经济损失估计为 1814,775 非洲金融共同体法郎（3045.01 美元）。

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.
