ABSTRACT

Background: Streptococcus pneumoniae and Haemophilus influenzae colonize the mucosal membrane of the nasopharynx and throat of healthy children, and constitute the main pathogen bacteria responsible of morbidity and mortality due to acute respiratory infections in the world. Objective: To assess the influence of the sample site on the isolation of Streptococcus pneumoniae and Haemophilus influenzae from the upper respiratory tract in healthy children. Material and methods: We studied 358 healthy children from three day care centers in Marianao, City of Habana. Nasal and throat swabs were taken from each of them. Percentages of isolation of both germs by the two sampling technique were compared. Results: In 13.1% of children both microorganisms were isolated. By nasal swab S. pneumoniae was isolated in 15.1% of children, unlike throat swab, which reported S. pneumoniae isolation in 4.5%. In 64.2% of children H. influenzae was isolated by throat swab, while by nasal swab this agent was isolated in 37.7%. It was found a poor coincidence between both sites of sample for H. influenzae isolation and there was no coincidence for S. pneumoniae isolation, nor for the presence of both germs in a same child. Conclusions: The importance of the sample site in the isolation of Streptococcus pneumoniae and Haemophilus influenzae from the upper respiratory tract is demonstrated, as well as the influence of the nasal and throat swab on the detection of carrier status of both germs.
