GOTERA ZAMBRANO, Jennifer Lucila et al. Serum prevalence of respiratory viruses and atypical bacteria in a population group of Zulia State, Venezuela. Rev. Soc. Ven. Microbiol. [online]. 2012, vol.32, n.2, pp.148-152. ISSN 1315-2556.

In this study we determined the prevalence of respiratory viruses and atypical bacteria in a population group of Zulia State between June 2008 and June 2010. The group included 224 individuals with respiratory infections due to different causes. The serum determination of IgG anti-Mycoplasma pneumoniae, Legionella pneumophila serogroup 1, Costella burnetii, Chlamydophila pneumoniae, adenovirus, influenza A and B, parainfluenza 1, 2, 3, and sincicial respiratory virus (SRV), was done by indirect immunofluorescency. In 100% of the patients analyzed we detected antibodies against the respiratory viruses evaluated (p<0.05), while in 26.3% we demonstrated seropositivity against atypical bacteria. Adenoviruses presented the highest percentage (79.4%), followed by SRV (76.7%), (p<0.001) in relation to parainfluenza 1, 2, 3, and influenza A and B (58.9%). There was greater prevalence (p<0.001) of anti-Chlamydophila pneumonia IgG (27.6%) when comparing it with the rest of the bacteria. Of the population analyzed, 33.9% (76/224) (p<0.001) presented antibodies against the pathogens. This demonstrates the circulation of respiratory viruses and atypical bacteria in the population group evaluated, which is extremely useful for knowing the dynamics and epidemiology of respiratory infections and for setting the bases for implementation of an active surveillance system at Zulia State.
