Zoonotic Potential of Brucella microti

Area of Science:

• Zoonotic diseases
• Microbiology
• Mammalogy

Background:

• Brucella microti is a known pathogen of rodents and wild mammals.
• Emerging infectious diseases transmitted from animals to humans are a growing public health concern.
• Rodent-borne pathogens represent a significant, yet often under-monitored, reservoir for zoonotic diseases.

Purpose of the Study:

• To report the first probable case of Brucella microti infection in a human.
• To provide a comprehensive clinical and laboratory description of this probable human zoonotic infection.
• To emphasize the potential of Brucella microti as an emerging zoonotic pathogen.

Main Methods:

• Clinical case description and detailed laboratory analysis of a mammalogist with suspected Brucella infection.
• Epidemiological investigation, including a history of a rodent bite.
• Isolation and identification of the pathogen from an infected vole.
• Serological testing (slow agglutination test) of the human patient.

Main Results:

• A mammalogist presented with symptoms consistent with a zoonotic infection.
• A probable epidemiological link was established through a bite from an infected rodent.
• Brucella microti was isolated from a sick vole, confirming its presence in the local wildlife.
• The patient exhibited a specific serological response indicative of Brucella microti infection.

Conclusions:

• The described human illness was likely caused by Brucella microti, an emerging zoonotic pathogen transmitted by rodents.
• This case underscores the importance of recognizing Brucella microti as a potential human pathogen.
• Continuous monitoring of rodents and wildlife for Brucella microti and other atypical brucellae is crucial for public health surveillance.
