Mycoplasmas in diseases of humans
Abstract:
The roles of Mycoplasma pneumoniae, M. hominis and Ureaplasma urealyticum in diseases of humans are currently under investigation. M. pneumoniae, which causes primary atypical pneumonia, is a well established pathogen of the respiratory tract. Complications of infection by this organism are also being recognized; they include disorders of the hematopoietic, cardiovascular, central nervous, musculoskeletal, cutaneous and gastrointestinal systems. The roles of the genital mycoplasmas M. hominis and U. urealyticum are controversial but may include infections of the genitourinary tract and in pregnancy as well as diseases of the newborn, such as neonatal pneumonia and meningitis. In this review atypical pneumonia due to M. pneumoniae is described and the role of mycoplasmas in other diseases is discussed.
Insights
Mycoplasma pneumoniae causes atypical pneumonia and other systemic complications. The roles of genital mycoplasmas like M. hominis and Ureaplasma urealyticum in human diseases are under investigation.
Area of Science:
- Microbiology
- Infectious Diseases
- Human Pathogens
Background:
- Mycoplasma pneumoniae is a known cause of primary atypical pneumonia.
- The broader roles of M. pneumoniae and genital mycoplasmas (M. hominis, Ureaplasma urealyticum) in human health are under investigation.
- Potential complications of M. pneumoniae extend to multiple organ systems.
Purpose of the Study:
- To review the established role of Mycoplasma pneumoniae in atypical pneumonia.
- To discuss the potential involvement of M. pneumoniae and genital mycoplasmas in a wider range of human diseases.
- To explore the controversial roles of M. hominis and U. urealyticum.
Main Methods:
- Literature review of Mycoplasma infections in humans.
- Synthesis of current research on M. pneumoniae pathogenesis.
- Analysis of evidence linking genital mycoplasmas to genitourinary, pregnancy, and neonatal conditions.
Main Results:
- M. pneumoniae is confirmed as a respiratory pathogen causing atypical pneumonia.
- Documented complications of M. pneumoniae include hematopoietic, cardiovascular, nervous, musculoskeletal, cutaneous, and gastrointestinal disorders.
- The roles of M. hominis and U. urealyticum remain controversial, with suspected links to genitourinary infections, pregnancy complications, and neonatal diseases like pneumonia and meningitis.
Conclusions:
- M. pneumoniae is a significant pathogen with diverse extrapulmonary manifestations.
- Further research is needed to clarify the clinical significance of M. hominis and U. urealyticum in human disease.
- Mycoplasmas represent an important area of study in infectious disease etiology.
