Article Synopsis
- MAH (Mycobacterium avium subsp. hominissuis) is a common mycobacterium causing infections in humans and animals, particularly linked to outbreaks in pigs.
- The study analyzed 50 MAH isolates from pigs in Japan, revealing a genetic connection between these isolates and those found in humans from North America, Europe, and Russia, but not in East Asia.
- Researchers identified a new lineage of MAH (SC5) and emphasized that pig farms are influenced by environmental strains and human infections, highlighting two main transmission routes: environmental exposure and pig movement.

Article Synopsis
- MAH is a significant cause of non-tuberculosis mycobacterial infections in both humans and pigs, with limited research on pig isolates despite their potential role in human infections.
- The study sequenced 30 draft genomes of MAH from pigs in Japan, revealing genome lengths ranging from 4.8 to 5.6 million base pairs, with thousands of coding genes and several predicted virulence factors.
- Findings from this research will aid in understanding MAH's ecology and support future genome-based epidemiological studies.

This study evaluated the occurrence of granulomatous lymphadenitis and its association with Actinobacillus spp. in 151 653 slaughtered pigs. Markedly enlarged pulmonary hilar, mediastinal, mandibular or hepatic lymph nodes were detected in 6 castrated males.

- A 6-month-old pig exhibited signs of lethargy, reduced appetite, and difficulty walking before euthanasia.
- At necropsy, severe hemorrhagic lesions were found in the spleen, with gram-positive bacteria identified from multiple organs.
- Genetic analysis confirmed these bacteria as a new Arcanobacterium species causing significant organ damage and acute splenic inflammation in the pig.
