Summary

Rhodococcus erythropolis rarely causes musculoskeletal infections. This case details a successful treatment of a foot infection caused by this rare bacterium following joint fusion surgery.

Diabetic Foot Ulcer

Diabetic Foot Ulcer

Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Area of Science:

Medical Microbiology
Orthopedic Surgery

Background:

Musculoskeletal infections are uncommon in Rhodococcus species, with limited documented cases.
Rhodococcus erythropolis is an opportunistic pathogen rarely implicated in bone and joint infections.

Observation:

A 53-year-old woman presented with persistent pain, swelling, and nonunion a year after first metatarsophalangeal joint fusion surgery.
Revision arthrodesis was performed, and tissue samples identified Rhodococcus erythropolis as the causative agent.

Findings:

The patient's symptoms resolved following a course of oral antibiotics.
Successful union of the first metatarsophalangeal joint was achieved one year after revision surgery.

Implications:

This case represents the first reported instance of a musculoskeletal infection specifically caused by Rhodococcus erythropolis.
