Species[1]

Brochothrix is genus of Gram-positive, nonmotile, catalase-positive, facultatively anaerobic bacteria that are nonmotile and form regular rod-shaped cells. The name Brochothrix is derived from the Greek noun brochos meaning loop and the Greek noun thrix meaning thread, from exponential-phase cultures which often show rods occurring in long, kinked, filamentous-like chains which bend and loop to give characteristic knotted masses.[2] The genus is mostly associated with spoilage of high value food, such as meat and fish, caused by off-odor development. The type species is B. thermosphacta and the only other species in the genus is B. campestris . There is no evidence that any Brochothrix strain is pathogenic to humans or animals.[3]

History

[edit | edit source]

The first Brochothrix species, Brochothrix thermosphacta, was isolated from pork sausage in 1953. However, the genus was not recognized as distinct until 1976.[4][2]
