Habitat of Mycoplasma pneumoniae They are found in the mucosa of upper respiratory tract (UTR) and urogenital tract of humans. Also found in oral cavity. They are also present in sewage, plants, animals, insects, humans and hot springs. They grow slowly than bacteria. They are self-replicating bacteria. They are atypical bacteria. They do not grow in the environment. They depends …
Pathogenesis of Mycoplasma pneumoniae M. pneumoniae is an extracellular pathogen transmitted by respiratory droplets expectorated during coughing which then adheres to the respiratory epithelium by means of a specialized attachment structure that forms at one end of the cell. M. pneumoniae possesses a membrane-associated protein, P1, which functions as a cytoadhesin. The adhesions interact specifically with sialated glycoprotein receptors at …

Laboratory diagnosis of Mycoplasma pneumoniae Specimen Ideal specimens are throat swabs and nasopharyngeal aspirates, lung biopsies, expectorated sputum. Washings are more reliable than sputum specimens because most infected patients have a dry, nonproductive cough and do not produce sputum. Microscopy Test is not useful because organisms do not have a cell wall and do not stain with conventional reagents Culture …
