Human diseases associated with mycoplasms. With an appendix on simple culture techniques

Area of Science:

• Microbiology
• Pathogen Discovery
• Veterinary Medicine

Background:

• Mycoplasmas, formerly pleuropneumonia-like organisms (PPLO), are wall-less microorganisms.
• Over 40 veterinary species are known pathogens, causing pneumonia, arthritis, and arteritis in lower mammals.
• Mycoplasma pneumoniae is the primary human pathogen, causing atypical pneumonia and associated complications.

Purpose of the Study:

• To review the role of mycoplasmas as pathogens in veterinary and human medicine.
• To discuss the clinical manifestations and associated diseases caused by various mycoplasma species.
• To highlight the need for further research into less understood associations, such as with neoplastic disease and rheumatoid arthritis.

Main Methods:

• Literature review of mycoplasma research.
• Analysis of documented cases and etiological associations.
• Synthesis of information on mycoplasma characteristics and pathogenicity.

Main Results:

• Mycoplasmas are significant veterinary pathogens, causing widespread disease in mammals.
• Mycoplasma pneumoniae is a well-established cause of human respiratory illness, with noted hematologic, neurologic, and dermatologic complications.
• Mycoplasma hominis is linked to febrile pregnancy complications, while T-strain mycoplasmas remain unassociated with disease despite ubiquity.

Conclusions:

• Mycoplasmas represent a diverse group of pathogens with significant impact on animal and human health.
• Mycoplasma pneumoniae is a critical focus for respiratory disease research and management.
• Further investigation is required to clarify the role of mycoplasmas in neoplastic diseases and rheumatoid arthritis.
