Abstract:

Bovine hypodermosis has been known as a veterinary disease that mainly caused by Hypoderma bovis and Hypoderma lineatum. This study aimed to determine sero-prevalence of cattle grubs in Mosul, Iraq utilizing indirect ELISA as well as effect of some risk factors on prevalence of hypodermosis. A total of two hundred blood specimens were collected from healthy and infested cattle through direct palpation. All samples were collected from cattle at Teaching Veterinary Hospital, Mosul abattoir, Kokjali and Bazwaya region during October 2020 to March 2021. Outcomes of iELISA showed 40.5% as an infestation rate of hypodermosis. Notably, infestation intensity has distributed as light, moderate and sever 11, 18.5 and 70.3% respectively. Interestingly, highest seroprevalence of hypodermosis was recorded in October 67.7%, and the lowest was recorded in February and March 22.2%, 25% respectively. Observations of current study also recorded the infection rate in age was 54.7% in animals less than 3 years old, and the lowest was 16% in animals more than 3 years old. Moreover, breed showed a significant risk factor 53.8% for imported cattle and 14.7% for local breed. Importantly, risk factor concerning area recorded the highest rate in Kokjali 52.2%. In contrast, the lowest rate recorded in Teaching Veterinary Hospital 14.8%. The present study is the first investigation to identify cattle hypodermosis by iELISA in Mosul, Iraq. iELISA has been approved as the best diagnostic tool for early detection of hypodermosis during the migrating phase. Interestingly, age, breed and months of study were significant risk factors.
