Salmonella paratyphi osteomyelitis and psoas abscess

Area of Science:

• Infectious Diseases
• Orthopedics
• Microbiology

Background:

• Bone and joint infections from Salmonella species are rare, representing less than 1% of all Salmonella infections.
• Salmonella typhi is the most common Salmonella serotype implicated in these infections.
• Joint infections caused by Salmonella paratyphi are infrequently reported in medical literature.

Observation:

• A rare case of osteomyelitis caused by Salmonella paratyphi A was identified.
• The patient also presented with a psoas abscess, a complication not previously documented in association with S. paratyphi A.

Findings:

• This report details a unique case of Salmonella paratyphi A osteomyelitis.
• The co-occurrence of a psoas abscess with S. paratyphi A osteomyelitis is described for the first time.

Implications:

• This case expands the known clinical spectrum of Salmonella paratyphi A infections.
• Highlights the importance of considering Salmonella paratyphi A in the differential diagnosis of bone and joint infections, particularly with unusual presentations like psoas abscess.
• Contributes to the limited literature on S. paratyphi joint infections, emphasizing the need for further research.
