Gallibacterium

Gallibacterium is a genus of bacteria from the family Enterobacteriaceae, first described in 2006. It is named after the Gallibacterium gallinarum species, which was isolated from the ceca of chickens. Gallibacterium species are Gram-negative, facultatively anaerobic, and rod-shaped bacteria. They are known for their ability to produce hydrogen sulfide, which can be detected using a lead acetate paper test. This genus is of particular interest to researchers due to its potential role in the gut microbiota of chickens and its ability to degrade certain compounds, such as aromatic hydrocarbons. Gallibacterium species have been found to be resistant to several antibiotics, including ampicillin and tetracycline, which is a concern for their potential role in antibiotic resistance. Further research is needed to fully understand the ecological role and clinical significance of Gallibacterium species.
