AI Article Synopsis
- Bovine tuberculosis, caused by Mycobacterium bovis, primarily affects cattle but can also infect other mammals, including pigs.
- In a study analyzing 250 M. bovis isolates from pigs in Argentina, over half were categorized into two main spoligotypes, with SB0140 being the most common.
- The research identified shared genotypes between pigs and cattle, indicating pigs could be a source of M. bovis infection for cattle, although some unique patterns were found only in pigs.
Article Abstract
Bovine tuberculosis is caused by Mycobacterium bovis and affects primarily cattle, among many other mammal species. In this study, 250 isolates of M. bovis collected from pigs slaughtered in Argentina were typed by spoligotyping. Over half of the isolates (66%) grouped into two spoligotypes. Moreover, SB0140 was the most frequent spoligotype detected in the three performed samplings. In addition, 195 isolates were typed through variable number of tandem repeats (VNTR) by selecting 7 loci (MIRU 16–26– 31 and ETR A–B–C–D). The relationship among the patterns was performed using a goeBURST algorithm and the main clonal complexes grouped 110 isolates (56%). Although pigs shared genotypes with cattle (n = 21), some patterns were detected only in pigs (n=14). These findings suggest the pig as a source ofM. bovis infection to cattle.
