Arcobacter cryaerophilus gv. occultus strain LMG 29976

Arcobacter cryaerophilus gv. occultus strain LMG 29976 is a microaerophilic, Gram-negative bacterium characterized by its curved rod shape and motility, attributed to the presence of flagella. This strain has a single replicon and is known to infect a variety of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and several other species such as pigs, dogs, and various birds. The strain is associated with several health effects in both humans and animals, leading to conditions such as bacteremia, sepsis, diarrhea, gastroenteritis, and reproductive issues like abortion and mastitis. Notably, it is considered enteropathogenic, indicating its role in gastrointestinal infections. The presence of Arcobacter cryaerophilus in diverse hosts highlights its ecological adaptability and potential zoonotic implications. Its ability to thrive under microaerophilic conditions suggests that it may occupy specific niches within the gastrointestinal tracts of its hosts, where oxygen levels are lower than atmospheric levels. This adaptability may facilitate its transmission among animals and to humans, raising concerns for public health in relation to food safety and zoonotic disease transmission. Further understanding of this strain's ecology and pathogenic mechanisms could inform strategies for managing infections it causes.
