Abstract:
OBJECTIVETo reveal the enterovirus infection within children suffering hand-foot-mouth disease (HFMD) in the Capital Institute of Pediatrics from Aprial to August, 2009, for the sake of clinical diagnosis and treatment.
METHODSBoth throat swab and vesicle fluid were taken respectively from 159 children with HFMD. And RNA were extracted from each sample followed with real-time fluorescence quantitative RT-PCR kits with three reagents: universal enterovirus primer, Coxsackievirus A16 (CA16) primer and enterovirus 71 (EV71) primer. Parts of postivive samples were sequenced and analyzed.
RESULTS(1) EV genes were detected from 152 cases, of which, 102 cases were positive for CA16 and 43 were positive for EV71. (2) CV16:EV71 was 2.37:1. The positive rates of throat swabs and vesicle fluid samples were not statistically significant. (3) The PCR results were same with that of sequence analysis.
CONCLUSIONThe hand-foot-mouth disease recently appeared in our hospital was mainly related to the EV71 or CA16 infection. And the percentage of EV71 infections obviously increased compared to that of 2007.
