Mycobacterium microti is a member of the Mycobacterium tuberculosis complex that seldom causes disease in livestock and humans. This study evaluated the effects on immunodiagnosis and the pathological findings in goats after experimental exposure by different routes and doses to M. microti.

Article Synopsis
  • * Researchers in France from 2000 to 2010 used genetic typing methods to study the diversity of this pathogen in humans, cattle, and wildlife, revealing varied genetic patterns.
  • * Findings indicate that most human infections likely originated abroad or were reactivations rather than local strains, yet some genetic similarities between human and cattle isolates were identified, highlighting the need for global control efforts.

The single and comparative intradermal tuberculin tests (SITT and CITT) are official in vivo tests for bovine tuberculosis (TB) diagnosis using bovine and avian purified protein derivatives (PPD-B and PPD-A). Infection with bacteria other than Mycobacterium tuberculosis complex (MTC) can result in nonspecific reactions to these tests. We evaluated the performance of the skin test with PPDs and new defined antigens in the guinea pig model.

Mammalian tuberculosis (TB) is a zoonotic disease mainly due to (). A current challenge for its eradication is understanding its transmission within multi-host systems. Improvements in long-read sequencing technologies have made it possible to obtain complete bacterial genomes that provide a comprehensive view of species-specific genomic features.
