Rat bite fever: a misnomer?

Area of Science:

• Infectious Diseases
• Microbiology
• Public Health

Background:

• Rat bite fever is a zoonotic disease transmitted from rodents to humans.
• Streptobacillus moniliformis is the causative agent, often difficult to culture.
• Human-rodent contact is frequent, suggesting underdiagnosis of this infection.

Purpose of the Study:

• To report a case of rat bite fever in a young man.
• To highlight diagnostic challenges and advancements.
• To emphasize the importance of timely treatment.

Main Methods:

• Clinical case presentation of a young man with symptoms including fever, vomiting, joint pain, and abnormal liver function.
• Review of patient's history for potential exposure to rodents.
• Treatment with broad-spectrum antibiotics.
• Mention of polymerase chain reaction (PCR) as a reliable diagnostic tool.

Main Results:

• The patient recovered completely after antibiotic treatment.
• The infection was linked to handling a dead rat, without a direct bite.
• PCR testing facilitates reliable identification of Streptobacillus moniliformis.

Conclusions:

• Rat bite fever is an underdiagnosed zoonotic infection.
• Early diagnosis and appropriate antibiotic therapy are crucial for patient recovery.
• Advancements in molecular diagnostics like PCR improve detection rates.
