Abstract
OBJECTIVE: To investigate the distribution of pathogens of children with community acquired pneumonia (CAP) from the Chongqing area. METHODS: Nasopharyngeal specimens and blood specimens of 1 613 children with CAP were collected between January 2014 and December 2014 for bacterial culture and detection of 7 respiratory viruses and antibodies against Mycoplasma pneumoniae (MP). RESULTS: The overall positive rate of bacteria was 50.22% (810 cases). Hemophilus parainfluenzae (40.8%), Streptococcus pneumonia (29.7%) and Moraxelle catarrhalis (7.3%) were the predominant ones. Among the viruses, the top detected virus was respiratory syncytial virus (RSV, 58.3%), followed by parainfluenza virus type3 (17.4%) and adenovirus (14.3%). A total of 481 cases (29.82%) were MP-positive. The co-infection rate was 32.18% (519 cases), and the mixed infections of bacteria and viruses were common (47.4%). CONCLUSIONS: RSV and Hemophilus parainfluenzae are the major pathogens of CAP in children from the Chongqing area. MP is also an important pathogen. The co-infection of bacteria and viruses is prevalent.
