Plain-English summary
Bovine tuberculosis (BTB) is a serious disease caused by bacteria that can affect both animals and humans, primarily spreading among cattle but also to other mammals. In this study, researchers looked at several animals, including alpacas, cattle, horses, dogs, a sheep, and a cat from the same farm, to see if they had BTB. Most of the animals were put to sleep after tests showed they might be infected, and samples were taken for further analysis. The tests revealed specific genetic patterns in the bacteria from some of the animals, indicating a connection between the infections. The findings highlight the importance of understanding how BTB can spread between different species.
Abstract
is one of the most dangerous pathogens of both animals and humans. Bovine tuberculosis (BTB) is a disease caused by mycobacteria belonging to thecomplex (MTBC), which spreads mainly among domestic cattle but also to mammals other than cattle. The transmission of MTBC between different species requires research and epidemiological investigations to control its spread. When multiple species are a reservoir of infection, it poses a significant public health and veterinary concern. In this study, the diagnosis of alpaca, cattle, horses, dogs, a sheep and a cat from one farm suspected of bovine tuberculosis was performed. The animals (except for one horse, the dogs and the cat) were euthanised after the intradermal tuberculin tests. Mycobacterial isolation from animal tissue samples was performed. The obtainedstrains were genotyped using spoligotyping and mycobacterial interspersed repetitive unit-variable number tandem repeat (MIRU-VNTR) methods. The isolates from a horse, two cows, a sheep and an alpaca were classified as(). The singlespoligotype SB0666 pattern was isolated, and the MIRU-VNTR results presented the same 222632237401435 patterns. The molecular investigation uncovered information on the relationship of.
