DETECTION OF HIGH-PATHOGENICITY ISLAND-HARBORING ESCHERICHIA COLI ISOLATED FROM CHILDREN WITH DIARRHEA DISEASE IN CHINA

[Objective] To investigate the etiologicla status of etiologica status of high-pathogenicity island-harboring Escherichia coil(HPIEC) in dianhea disease among children. [Method] Diarrheagenic Esoherichia coli was isolated and identified from the stool specimens of 1032 children with dianhea diseases by culturing, serotyping, Polymerase chain reaction amplification (PCR), the High-pathogenicity island-harboring Esoherichia coli (HPIEC) was identified by PCR and in situ hybridization. [Results] A total of 652 strains of E.coli isolated from 1032 stool specimens and confirmed by serotyping, PCR and colony hybridization out of which 225 were identified as diarrheagenic E.coil,including 20 EPEC,81 ETEC, 47 SLTEC, 74 ESIEC, and 3 EIEC strains. 112(17.2%)irp2 virulent gene positive E.coli (HPIEC) were detected from the 652 strains, out of which 24 were from the 74 ESIEC strains and 17 from the 47 SLTEC strains. The typical clinical symptoms of children with diarrhea disease caused by HPI- harboring E.coli included anorexia(87.5%) ,abdominal pain(58.0%), diarrhea (75.9%,Over six episoders, mostly of mucous stool a day), and fever(50.9%). [Conclusion] High-pathogenicity island-harboring E.coli is one of the important pathogens of diarrhea diseases in children.

天麻共生密环菌生长情况的实验研究

密环菌（Arimillia mellea）属担子菌纲白蘑科密环菌属真菌，寄生于阔叶树的根、茎、叶。密环菌不仅有一定的药用价值，而且是栽培名贵中药天麻的必备共生菌。密环菌以菌索形式侵入天麻为其生长提供营养，其品质优劣及生长情况，对天麻块茎的生长影响很大。为了探讨密环菌本身的生长情况，从2001年11月～2002年11月采用组织培养方法，对拌栽天麻密环菌零代、1代进行了研究。
