Abstract
Bovine nodular thelitis is a granulomatous dermatitis associated with infection with acid-fast bacteria. To identify the mycobacterium responsible for this infection, we conducted phylogenetic investigations based on partial sequencing of 6 genes. These bacteria were identified as an undescribed Mycobacterium species that was phylogenetically related to M. leprae and M. lepromatosis.
Highlights
Bovine nodular thelitis is a granulomatous dermatitis associated with infection with acid-fast bacteria
This granulomatous dermatitis is associated with acid-fast bacilli and believed to have a mycobacterial origin of infection [2,4]
The same well-sustained relationship with M. leprae and separation from M. haemophilum was inferred from sodA, tuf, and tmRNA gene phylogenies, but the lack of corresponding sequences for M. lepromatosis impaired this analysis
Summary
Bovine nodular thelitis is a granulomatous dermatitis associated with infection with acid-fast bacteria. Bovine nodular thelitis is a chronic and enzootic cutaneous disease that was first described in France in 1963 and in Japan and Switzerland [2,3,4]. We used a multigene sequencing phylogenetic approach described previously [5] to identify the mycobacterium responsible for bovine nodular thelitis.
