Why are Svalbard Arctic foxes Brucella spp. seronegative?

چکیده
Arctic foxes (Vulpes lagopus) are susceptible to smooth Brucella (s-Brucella) infection and may be exposed such bacteria through the consumption of infected marine mammals, as implied by finding s-Brucella antibodies in polar bears (Ursus maritimus). Svalbard have not previously been investigated for s-Brucella antibodies, but antibodies detected Iceland, Alaska (USA) Russia. We blood from using an indirect enzyme-linked immunosorbent assay (iELISA). The animals (0–13 years old) were either caught fur trappers (1995–2003, n = 403) or found dead (1995 2003, n = 3). No seropositive detected. Morbidity mortality due cannot ruled out. However, no known, large disease outbreaks unknown aetiology reported. Furthermore, it is unlikely that fox resistant other populations susceptible, there circumpolar connectivity between populations. discrepancy findings Iceland surprising both on islands with known local sources exposure s-Brucella other than mammals. our negative suggest mammals a major source this species. Comparative investigations needed order draw conclusions regarding epizootiology s-Brucella in Iceland.

Brucellosis is endemic in Bangladesh both in humans and in animals. A number of reasons complicate the diagnosis, as bovine brucellosis can be diagnosed by various serological tests. But the tests have a limitation; when the organism remains intracellular, the disease goes into chronic stage and the antibody titres may decline. The present study was conducted for isolation and detection of Bruc...
