Rhodococcus equi is a Gram-positive coccoid bacteria. The organism commonly lives in dry and dusty soil and can be important for diseases of domesticated animals (horses and goats). The frequency of infection reaches near 60 percent. R. equi is the most important pathogen of pneumonia of foals. In addition there is a the possibility, that the pathogen can transfer to humans. The most endangered groups are immunsupprimised people and AIDS-patients.

Additional recommended knowledge

In taxonomies, R. equi can have the synonymes Corynebacterium equi, Bacillus hoagii, Corynebacterium purulentus, Mycobacterium equi, Mycobacterium restrictum, Nocardia restricta and Proactinomyces restrictus.
