Brucellosis in wildlife.

چکیده

Brucellae infections have been documented world-wide over the years in a great variety of terrestrial wildlife species. Recently, brucellae infections have also been reported in a wide variety of marine mammals. A very important consideration with regard to terrestrial brucellosis in wildlife is to distinguish between a spillover of infection from domestic animals and a sustainable infection in wild species. The probability of brucellosis becoming established and being sustainable in a species depends on a combination of factors including host susceptibility, infectious dose, contact with infected animals, management and environmental factors. In this context, the development of the game farming industry appears to have contributed to the re-emergence of brucellosis. The gold standard in brucellosis diagnosis remains the isolation of brucellae. If brucellosis is suspected in an animal or a wildlife population following positive serological results, attempts to isolate the organism should always be performed. The release of anti-brucellae vaccine strain in wildlife is of concern because this could lead to environmental contamination and infection of other wild species. Therefore, the appropriate dosage of the vaccine in target species as well as the safety of the vaccine in non-target species must be addressed in technical terms in order to assist decision-making regarding the management of wildlife brucellosis.

Brucellosis in terrestrial wildlife.

The epidemiological link between brucellosis in wildlife and brucellosis in livestock and people is widely recognised. When studying brucellosis in wildlife, three questions arise: (i) Is this the result of a spillover from livestock or a sustainable infection in one or more host species of wildlife? (ii) Does wildlife brucellosis represent a reservoir of Brucella strains for livestock? (iii) I...

Brucellosis Transmission between Wildlife and Livestock in the Greater Yellowstone Ecosystem: Inferences from DNA Genotyping.

The wildlife of the Greater Yellowstone Ecosystem carries brucellosis, which was first introduced to the area by cattle in the 19th century. Brucellosis transmission between wildlife and livestock has been difficult to study due to challenges in culturing the causative agent, Brucella abortus . We examined B. abortus transmission between American bison ( Bison bison ), Rocky Mountain elk ( Cerv...

Diagnosis of brucellosis in livestock and wildlife.

AIM To describe and discuss the merits of various direct and indirect methods applied in vitro (mainly on blood or milk) or in vivo (allergic test) for the diagnosis of brucellosis in animals. METHODS The recent literature on brucellosis diagnostic tests was reviewed. These diagnostic tests are applied with different goals, such as national screening, confirmatory diagnosis, certification, an...
