Mycoplasma

  1. 1. “Mycoplasma” Seminar presented by Ashish Diwakar M.Sc.Microbiology II Semester School of Studies in Microbiology Vagdevi Bhavan, Vikram University,Ujjain (M.P.)
  2. 2. Synopsis • Introduction of Mycoplasma • History of Mycoplasma • Morphology of Mycoplasma • Chemical composition of mycoplasma • Classification of Mycoplasma • Reproduction of Mcoplasma • Structure of Mycoplasma • Pathogenecity of mycoplasma • Treatment • Conclusion • References
  3. 3. Introduction • Unicellular Prokaryote • Gram-Positive Bacteria • Lack cell wall- Pleomorphic • Osmotic Shock / Detergent-Sensitive • Antibiotics-Tetracyclin / Chloremphenicol-Sensitive • They are the smallest bacteria capable of autonomous growth • Facultative anaerobes / obligate anaerobes • Low G+C%, 23-41% • Mostly require sterol for their growth • (but some genera do not require sterol – such as Acholeplasma, Asteroleplasma, Mesoplasma)
  4. 4. History • Discovered by Pasture in 1843. • Isolated from pleural fluid of cattle. • It was called as Mycoplasma mycoides. • Nocard & Roux first cultured Mycoplasma in1898. • In 1929, Nowak called them PPLO.
  5. 5. Morphology Size :- 300nm to 0.2nm Shape :- Coccoidal,Diploform,Filamentus,Spiral shape &Teardrop shape.
  6. 6. Colonical appearance & Colony Cheracterstics:- • Colony developed on the solied Medium. • Show nippled or fried egg colony.
  7. 7. Chemical Composition • Protein - 40-60% • Carbohydrate - 0.1% • DNA Content - 3-7% • Lipid - 8-20%
  8. 8. CLASSIFICATION Kingdom : Bacteria Division : Firmicutes Class : Mollicutes Order : Mycoplasmatales Family : Mycoplasmataceae Genus : Mycoplasma
  9. 9. Reproduction of Mycoplasma Binary fission Budding or Round body formation Filamentous formation
  10. 10. BINARY FISSION
  11. 11. STRUCTURE OF MYCOPLASMA
  12. 12. Pathogenesity • Extra cellular parasite • It Causes infection in Respiratory tract & Urinogenital tract • In Respiratory tract Cause Pneumonia • In Urinogenital tract Cause Male sterility Diseases Causeing Mechenism of Mycoplasma Attachment :- Host cell - Have - Glycoprotein
  13. 13. Penetration:- • Mucosa membrane penetrate • Attach on epithelial cells • Growth on epithelial cells • And destroy epithelial cells • Cause Pneumonia Treatment:- • Tetracyclin / Chloramphenicol / Erythromycin
  14. 14. Conclusion • Mycoplasma are peculier type of bacteria • as they requiring sterol for growth • They are cell wall less • some are pathogenic (humen diseses) • some are cattle/plants/insects parasite also
