Reservoirs of Brucella infection in nature

摘要: Brucellosis is a zoonosis caused by bacteria of the genus Brucella, which includes nine species: B. melitensis (goats and sheep as main reservoir hosts), abortus (cattle), suis (pigs), neotomae (desert woodrats), ovis (sheep), canis (dogs), ceti (whales), pinnipedialis (pinnipeds), microti (Microtus voles). The epidemic epizootic situation with brucellosis accounted for farm animals, are carriers three pathogens (B. melitensis, abortus, suis). Their ubiquitous distribution factor determining global prevalence above Brucella species on all continents in overwhelming majority countries. Consistent expansion pathogen ecological range 1990s findings new marine mammals (whales pinnipeds) some rodents. These proved to be also pathogenic terrestrial humans. All Brucella-infected animals considered paper tentatively divided into two groups. first most wild domestic animal species, birds, ticks that acquire infection hosts Brucella. second group (wild reindeer, hares, bison, probably saiga antelopes, dogs, mammals) may carry regardless hosts.
