Isolation of Acholeplasmatales from rabbit faeces
Laboratory Animals
|July 1, 1987
Summary
Acholeplasma laidlawii is commonly found in rabbit feces, indicating persistent infections. Two additional acholeplasma strains were identified in specified-pathogen-free rabbits, one possibly a new species.
Area of Science:
- Veterinary Microbiology
- Mycoplasmology
Background:
- Acholeplasma laidlawii is a common mycoplasma-like organism.
- Rabbits are used as animal models in various research settings.
Purpose of the Study:
- To investigate the prevalence of Acholeplasma laidlawii in conventional and specified-pathogen-free (SPF) rabbits.
- To identify and characterize other Acholeplasma species in SPF rabbits.
Main Methods:
- Fecal samples were collected from conventional and SPF rabbits.
- Isolation and identification of Acholeplasma species were performed using standard microbiological techniques.
- Serological tests were used for species identification.
Main Results:
- Acholeplasma laidlawii was isolated from 23.5% of conventional and 24% of SPF rabbits.
- Repeated isolations suggested persistent infections.
- Two additional acholeplasmas were isolated from SPF rabbits; one was related to Acholeplasma modicum, and the other was unidentified.
Conclusions:
- Acholeplasma laidlawii is prevalent in rabbit populations.
- Persistent infections with A. laidlawii are common in rabbits.
- The presence of novel Acholeplasma species in SPF rabbits warrants further investigation.
