The study titled, ‘A Novel Molecular Approach to Study Brucellosis in Cattle, Sheep, Goats and Camels in the Sultanate of Oman’ shows that cattle in the area have been infected by brucellosis. In Jebel Akhdar, 11.4 per cent goats were found infected and in Saham one per cent cattle and one per cent sheep were infected.
Speaking to Muscat Daily, Dr Yasmin el Tahir, assistant professor at the Department of Animal and Veterinary at the College of Agriculture and Marine Sciences in SQU said that brucellosis is a major bacterial zoonosis - a disease that can be transmitted to humans from animals.
The study which started in 2014 will be concluded by April 2018.
In Dhofar, blood samples were randomly collected from 50 farms in Dhofar during March and April 2015.
“In Batinah, the study was carried out to determine the sero-prevalence of brucellosis in livestock including sheep, goats and camels in different areas from March to April 2015. Blood samples of 248 animals (102 goats, 104 sheep and 42 camels) were tested for brucellosis.”
Dr Yasmin said, “The study team comprises members Al Ghalya al Toobi and Anfal al Farsi. We also have professors, doctors and technicians from SQU’s department of Animal Veterinary Sciences. While Al Ghalya worked in Jebel Akhdar, Anfal a masters student studied the Batinah area.”
Elaborating on who can be affected by it, Dr Yasmin said, “Different mammals including man, cattle, sheep, goats, camels, swine, rodents and marine mammals can be carriers. In the host species, the disease primarily affects the reproductive system with concomitant loss in productivity of animals. In human beings, infection is associated with a spectrum of non-pathognomonic symptoms which are often mis-diagnosed resulting in serious and debilitating manifestations,” she added.
In order to control brucellosis, comprehensive surveillance, pre and post-import testing is of paramount importance, Dr Yasmin said. “The overall aim of this study is firstly to determine the seroprevalence [prevalence in blood] of brucellosis in the most common domestic animals in Oman. It seeks to identify the risk factors associated with the disease, determine the prevalence of brucellosis in different regions of the sultanate, and above all shed light on the important reservoirs that serve to transmit brucella. This information will facilitate development of suitable control strategies to reduce the risk of this malady in man and animals,” she added.
A French team comprising, Dr Jay Maryne, Dr Virginie Mick and Corde Yannick from the Brucellosis Reference Laboratory in Paris has also approved the study, said Dr Yasmin.
