Proposal for classifying human strain navel and related simian mycoplasmas as Mycoplasma primatum sp. n
Abstract:
Mycoplasmas isolated from simian (Cercopithecus aethiops) tissues were shown to have biological, biochemical, and serological properties and electrophoretic cell protein patterns similar to strain Navel isolated from man 15 years ago. The simian and human Navel strains comprised a single serogroup, distinct from the established Mycoplasma and Acholeplasma species of the class Mollicutes. It is proposed that strains with the properties described be named Mycoplasma primatum.
Insights
New Mycoplasma strains from African green monkey tissues share traits with human strains. These findings suggest a new species, Mycoplasma primatum, distinct from known Mollicutes.
Area of Science:
- Microbiology
- Molecular Biology
- Immunology
Background:
- Mycoplasmas are bacteria lacking cell walls, belonging to the class Mollicutes.
- Previous research has identified various Mycoplasma species in both human and animal hosts.
- Understanding Mycoplasma diversity is crucial for diagnostics and treatment.
Purpose of the Study:
- To characterize Mycoplasmas isolated from simian (Cercopithecus aethiops) tissues.
- To compare these simian isolates with a previously identified human strain (Navel).
- To determine if these isolates represent a new species within the Mollicutes.
Main Methods:
- Isolation and culturing of Mycoplasma from simian tissues.
- Biological, biochemical, and serological characterization of isolates.
- Electrophoretic analysis of cell protein patterns.
- Serological comparison with known Mycoplasma and Acholeplasma species.
Main Results:
- Simian isolates exhibited biological, biochemical, and serological properties similar to human Navel strain.
- Electrophoretic cell protein patterns of simian and human strains were comparable.
- Both simian and human Navel strains formed a distinct serogroup.
- This serogroup was clearly differentiated from established Mycoplasma and Acholeplasma species.
Conclusions:
- The simian and human Navel strains represent a distinct serogroup.
- A new species, Mycoplasma primatum, is proposed for these strains.
- This classification expands the known diversity within the Mollicutes.
