Hemophilus aphrophilus osteomyelitis.

Area of Science:

• Microbiology
• Infectious Diseases
• Bacteriology

Background:

• Gram-negative bacilli, including Hemophilus aphrophilus, are increasingly recognized as potential pathogens.
• Hematogenous vertebral osteomyelitis is a serious condition often requiring prolonged treatment.

Observation:

• A case of vertebral osteomyelitis caused by Hemophilus aphrophilus following a lip laceration is presented.
• The patient's infection was successfully treated with parenteral penicillin.

Findings:

• Hemophilus aphrophilus, a slow-growing, aerobic, capnophilic gram-negative bacillus, was identified as the causative agent.
• Antimicrobial susceptibility data for 14 agents against this isolate are provided.

Implications:

• This case highlights the importance of considering unusual bacteria in the etiology of osteomyelitis.
• Understanding the antimicrobial profile of Hemophilus aphrophilus is crucial for effective treatment strategies.
• Parenteral penicillin demonstrated efficacy in treating this specific case of H. aphrophilus vertebral osteomyelitis.
