Rhodococcus hoagii: Difference between revisions

Revision as of 15:14, 18 August 2020

Background

Microbiology

Facultative intracellular, non-spore-forming, Gram-positive, weakly acid-fast coccobacillus
Found in dry and dusty soil
Makes red pigment, hence the name
Member of the actinomycetes group

Epidemiology

Infects domesticated animals
- Horses, and in foals it causes pneumonia
- Goats
- Pigs
- Sheep
- Cattle
Can infect immunocompromised people (HIV, etc)

Clinical Manifestations

Necrotizing pneumonia is usual presentation, as well as nodules, cavitation, pleural effusion, and lung abscess
Specifically in immunocompromised patients, it can cause a cavitary lung disease and is on the differential with mycobacteria and nocardiosis

Management

Treatment usually 6 months or longer
