Abstract
Brucellosis is a disease of animals caused by <em>Brucella</em> species and is transmissible to humans. This study was undertaken to determine the sero-prevalence of the disease in livestock including sheep and goats and camels, in different regions of Abu Dhabi emirate and to identify factors associated with the epidemiology of the disease. A serological study using 6126 blood samples from livestock were obtained from 267 farms (Izaba) during the period from January 2009 to December 2010. The Rose Bengal Plate Test and competitive ELISA were used as screening and confirmatory tests, respectively. The overall sero-prevalence of <em>Brucella</em> antibodies was 8.00% and 7.00% detected by the RBPT by c-ELISA respectively. <em>Brucella</em> prevalence was 8.3, 5.9 and 4.7% in Alain, Abu Dhabi and Western region. The prevalence of the disease was higher (8.4%) in sheep and goats than (4.4%) in camels respectively. The result showed that, the prevalence of brucellosis was significantly higher in females than male (p<0.04) Out of the 267 farms sampled in the study, 147 (55.1%) were infected with <em>Brucella</em>. There was strong correlation between herd size and prevalence of the disease, very large herds had significantly higher prevalence when compared with small ones. The study revealed light of a size able prevalence among livestock in Abu Dhabi Emirate and the results reflect the necessity of a control program of the disease is needed to be adopted.
Highlights
Brucellosis is an infectious bacterial disease caused by the genus Brucella and affecting a number of animal species (Hirsh and Zee, 1999)
Up to date, no systemic research on the epidemiology of brucellosis that cover all the regions of Abu Dhabi Emirate was carried out to best of our knowledge, the objective of this study was to investigate the seroprevalence of the disease in large number of different animal species including camel, sheep and goats distributed randomly in Abu Dhabi emirate and to elucidate the role of risk factors in the spread of the disease among livestock
This study was designed to systemically investigate the sero-prevalence and risk factors associated with brucellosis in different livestock species in Abu Dhabi Emirate
Summary
Brucellosis is an infectious bacterial disease caused by the genus Brucella and affecting a number of animal species (Hirsh and Zee, 1999). It is a worldwide zoonotic disease that is recognized as a major cause of heavy economic losses to the livestock industry and poses serious human health hazard (Ocholi et al, 2005). In animals, it is a significant cause of reproductive losses usually caused by B. abortus in cattle, B. melitensis and B. ovis in small ruminants, B. suis in pigs and B. canis in dogs (Khorasgani et al, 2008). The disease is reported in domestic animals and humans in Oman, Qatar, Kuwait and Saudi Arabia which share border with United Arab Emirates (Yasmin and Remya, 2011)
