Summary
Rhodococcus equi, a bacterium causing foal pneumonia, is an emerging zoonotic pathogen. It can infect immunocompromised and immunocompetent humans, with animals and their environment posing a potential source.
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Microbiology
Background:
- Rhodococcus equi is a gram-positive coccobacillus known for causing foal pneumonia and enteritis.
- Human infections with R. equi, first described in 1968, primarily affect immunocompromised individuals.
- Increasing reports indicate infections in immunocompetent hosts, highlighting a broader clinical spectrum.
Conclusions:
- Rhodococcus equi represents an emerging zoonotic threat with a broader host range than previously recognized.
- Virulence plasmids play a key role in the pathogenicity of R. equi across different hosts.
- A One Health approach considering animal and environmental sources is crucial for managing R. equi zoonoses.
