Participação do Mycoplasma pneumoniae na etiologia de infecções respiratórias agudas em Ribeirão Preto, São Paulo, Brasil

Abstract

Mycoplasma pneumoniae isolation was attempted in respiratory fluids from 64 patients with respiratory infection Complement fixation test (CF) and counterimmunoelectrophoresis (CIE) were used for Mycoplasma antibody detection using the patient sera. Mycoplasma pneumoniae was not isolated. Serologic diagnosis were positives in 3.1% (2/64) by CF test and 1.6% (1/64) by CIE. Serologic tests done in 200 health controls showed 4% (8/200) positives by CIE and 1% (2/200) by CF. The results showed differences in sensitivity among the serologic tests. CF seems to be more indicated for Mycoplasma infection diagnosis while, CIE could be used for Mycoplasmas serosurveys. The prevalence of Mycoplasma pneumoniae infections was low (3.1%) in the 64 patients during our study period.
