Rhodococcus hoagii is a well-known zoonotic disease, especially in foals. Its occurrence in humans is uncommon and usually occurs in immunocompromised patients. We present a case of Rhodococcus hoagii infection resulting in necrotizing pneumonia in a patient with advanced retroviral disease who had defaulted treatment. Effective treatment of Rhodococcus hoagii infection requires a combination of antibiotics. We also highlighted the importance of effective communication between clinicians and microbiologists so that prompt treatment can be initiated to improve patient outcomes.

Article Synopsis
- The study focuses on the "plastisphere," which refers to microbial communities that grow on plastic debris, raising environmental concerns due to their negative effects.
- Researchers found that microbial communities on microplastics were significantly different from those in soil and had more plastic-degrading microorganisms, particularly Nocardia and Rhodococcus.
- They confirmed that two specific microorganisms could degrade polyethylene (PE) by growing solely on it, causing significant weight loss and structural changes to the plastic, while also identifying genes involved in this biodegradation process.

Rhodococcus equi pneumonia is an important cause of mortality in foals worldwide. Virulent equine isolates harbour an 80-85kb virulence plasmid encoding six virulence-associated proteins (Vaps). VapA, the main virulence factor of this intracellular pathogen, is known to be a cell surface protein that creates an intracellular niche for R.

Rhodococcus equi is a facultative intracellular gram-positive coccobacillus which is a well-known cause of foal pneumonia and/or enteritis in equine veterinary medicine. More than 300 cases of R. equi infection have been reported since the first description of human disease in 1968.
