Japanese Macaques (Macaca fuscata) as Natural Reservoir of Bartonella quintana
Abstract:
Bartonella quintana bacteremia was detected in 6 (13.3%) of 45 wild-caught Japanese macaques (Macaca fuscata). Multilocus sequence typing of the isolates revealed that Japanese macaques were infected with a new and specific B. quintana sequence type. Free-ranging Japanese macaques thus represent another natural reservoir of B. quintana.
Insights
Bartonella quintana bacteria were found in wild Japanese macaques. These macaques carry a unique strain, establishing them as a new natural reservoir for Bartonella quintana infections.
Area of Science:
- Microbiology
- Infectious Diseases
- Veterinary Medicine
Background:
- Bartonella quintana is a bacterium known to cause human diseases like trench fever.
- Reservoirs and transmission routes of Bartonella quintana are not fully understood.
- Studies on zoonotic potential in wildlife are crucial for public health.
Purpose of the Study:
- To investigate the presence of Bartonella quintana in wild Japanese macaques.
- To characterize the genetic diversity of Bartonella quintana isolates from macaques.
- To determine if Japanese macaques represent a natural reservoir for Bartonella quintana.
Main Methods:
- Blood samples were collected from 45 wild-caught Japanese macaques.
- Bartonella quintana bacteremia was detected using molecular methods.
- Multilocus sequence typing (MLST) was performed on positive isolates.
Main Results:
- Bartonella quintana bacteremia was detected in 6 out of 45 macaques (13.3%).
- MLST revealed a novel and distinct Bartonella quintana sequence type in these macaques.
- This indicates a specific adaptation or strain within the macaque population.
Conclusions:
- Wild Japanese macaques harbor Bartonella quintana.
- Japanese macaques represent a newly identified natural reservoir for Bartonella quintana.
- Further research is needed to understand the transmission dynamics and public health implications.
