Brucellosis is an emerging zoonosis and an economically important infectious disease of livestock with worldwide distribution [14]. The disease is manifested by abortion and infertility and caused by Brucella spp. which are Gramnegative, facultative intracellular bacteria. Six species in the genus of Brucella are currently recognized on the basis of the phenotypic characteristics, antigenic pro...

To determine the role of different Brucella (B.) spp. in Bangladesh, 62 animal samples and 500 human sera were tested. Animal samples from cattle, goats and sheep (including milk, bull semen, vaginal swabs and placentas) were cultured for Brucella spp. Three test-positive human sera and all animal samples were screened by Brucella genus-specific real-time PCR (RT-PCR), and positive samples were...

Brucellosis is a reemerging worldwide zoonotic disease and the occurrence of the disease in humans is largely dependent on the animal reservoir [1]. In human it is mainly caused by Brucella melitensis. The highest rate of human infection is mainly in those areas where rates of brucellosis in sheep and goats are high [2,3] as sheep and goats are main reservoir of B. melitensis [4]. The preventio...

Brucellosis is one of the important zoonotic diseases among livestock. This study was carried out to estimate the prevalence of brucellosis and isolate Brucella spp. in sheep in Kassala State in the east of Sudan. Two thousand and five serum samples were randomly collected from nine different localities. All serum samples were examined by the Rose Bengal plate test (RBPT) and the modified RBPT ...

Brucella is one of the major zoonotic pathogens worldwide, and it is responsible for enormous economic losses as well as considerable human morbidity in endemic areas. The organism infects animals such as swine, cattle, goat, sheep, and dogs. Humans can become infected indirectly through contact with infected animals or by animal products consumption. Brucellosis occurs worldwide, but it is wel...

Brucellosis in domestic animals is a chronic disease that is characterized mainly by reproductive signs in cattle, buffaloes, pigs, sheep, goats and dogs. In females the disease is characterized by abortion, placenta retention, vaginal secretions, low fertility rate and also embryonic and neonatal death. In males, regular findings include epididymitis, orchitis, unior bilateral testicular atrop...

Brucellosis is a contagious disease caused by bacteria of genus Brucella. In livestock, it is mainly a reproductive disease of the sexually mature animals with predilection site of placenta, fetal fluids and testes of male animals Wadood 2009. It has been recognized as a global problem of wild and domestic animals, especially cattle, sheep and goats Rijpens [1]. The disease is primarily an occu...

Brucellosis is a global zoonotic disease, endemic in North African countries and around the Mediterranean.A prospective study of Brucella seroprevalence was conducted in north-western Libya (western mountains region). Blood samples collected over 13 months in the period December 2006 to January 2008 from 561 animals (goats, sheep, cattle and camels) and 546 human volunteers were tested for Bruc...

Brucellosis is a zoonotic disease that causes animal and human diseases. Vaccination is a major measure for prevention of brucellosis, but it is currently not possible to distinguish vaccinated animals from those that have been naturally infected. Therefore, in this study, we constructed the Brucella (B.) abortus 2380 wbkA mutant (2308ΔwbkA) and evaluated its virulence. The survival of 2308Δwbk...
