Genome degradation in Brucella ovis corresponds with narrowing of its host range and tissue tropism. [PDF]

PLoS ONE, 2009
Brucella ovis is a veterinary pathogen associated with epididymitis in sheep. Despite its genetic similarity to the zoonotic pathogens B. abortus, B. melitensis and B. suis, B. ovis does not cause zoonotic disease.

Molecular characterization of Brucella ovis in Argentina [PDF]

Veterinary Microbiology, 2020
Brucellosis in rams is caused by Brucella ovis or Brucella melitensis and it is considered one of the most important infectious diseases of males in sheep-raising countries. Molecular characterization of Brucella spp. achieved by multi-locus variable number of tandem repeats analysis (MLVA) is a powerful tool to genotype Brucella spp.

Risk Factors for the Spread of Brucellosis in Sheep and Goats in the Campania Region in the Years 2015–2020

Microorganisms, 2023
Brucella is a Gram-negative facultative intracellular pathogen that causes infection in sheep and goats (B. melitensis.); B. melitensis can also infect other animals.

An HWE-Family Histidine Kinase Modulates Brucella Cell Envelope Properties and Host Innate Immune Response. [PDF]

Mol Microbiol
The HWE‐family histidine kinase PhyK regulates the cell envelope structure of the intracellular pathogen Brucella ovis and affects how the host immune system responds to this bacterium. Deletion of phyK alters bacterial survival in the face of detergent stress and reduces immune activation in infected macrophages.

<i>Brucella</i> Infections in Camels and Abattoir Workers in the United Arab Emirates: One Health-Based Seroepidemiological and Molecular Insights. [PDF]

Transbound Emerg Dis
Brucellosis remains a critical zoonotic disease affecting livestock productivity and human health, especially in regions where intensive livestock husbandry is practiced. In the United Arab Emirates (UAE), camels contribute economically and culturally through meat, milk, and racing, yet data on brucellosis in camels and its zoonotic risk remain limited.

Epidemiology of <i>Brucella</i> Infection in Small Ruminants in the United Arab Emirates. [PDF]

Transbound Emerg Dis
Small ruminants are important livestock species, which function as a major source of protein, in the United Arab Emirates (UAE), although infections such as Brucella infection can hamper their productivity. However, there is currently a paucity of epidemiological data on Brucella infections in small ruminants in the UAE.

Investigating selective media for optimal isolation of Brucella spp. in South Africa

Onderstepoort Journal of Veterinary Research, 2020
Bovine brucellosis in South Africa is caused mainly by Brucella abortus biovar (bv.) 1 and less frequently by B. abortus bv. 2. Bacterial isolation is regarded as the gold standard for diagnosis of Brucella species; however, it is not very sensitive. The
