Colonization of mycoplasma in the upper respiratory tract of AIDS patients with pulmonary symptoms in Chennai, India
2005
Methods: A total of 130 sputum samples (100 from AIDS patients and 30 from non-HIV) were cultured on standard pleuropneumonia-like organisms (PPLO) glucose agar up to 3 wk. The plates were examined for the presence of fried-egg colonies characteristic of Mycoplasma. Subsequently the plates were stained using Diene’s stain. Sputum specimens from the AIDS patients were also screened for other bacterial pathogens. Results: Mycoplasmas were detected from 36 (36%) of the AIDS patients and only 5 (16.6%) of the non HIV control individuals with underlying pulmonary symptoms. Data on the detection rates of other microorganisms from the AIDS cases were also analysed. Interpretation & conclusion: This preliminary study provided supportive evidence that mycoplasma colonized in upper respiratory tract of individuals with AIDS to a larger extent than that of the non HIV subjects with pulmonary symptoms. Further studies need to be done to characterize mycoplasma isolates to species level.
