Analysis on Distribution of shigella Dysenteriae Flora and Drug Resistance in 2003 in Partial Regions of Zhejiang Province

Objective This analysis was to help understand the distribution of subtypes of Shigellae and their resistance to drags so as to improve the pertinence of preventive and cure measures and avoid the abuse of antibiotics. Methods 158 strains of Shigellae was identified and grouped in terms of GB16002-1995 and Kirby-Bauer Methods was used to determine their sensitivities to 14 antibiotics. Results In 158 strains of Shigellae，there were 113 strains of Sh. Flexneri(71.52％)，22 strains of Sh.Boydii(13.92％)，14 strains of Sh Soimet(8.86％)and 9 strains of Sh. Dysenteriae(5.70％)； 91 strains of shigellae were resistant to Amphicillin with One highest rate up to 95.60％ and the next was Streptomycin(72.53％)：bacteria were the most sensitive to Ceftazidime with a rate of 95.60％ Conclusion In recent years，there has been a notable change in One distribution of Shigella subtypes and their sensitivities to antibiotics in zhejiang province，and medical departments should strengthen the monitoring on subtypes of Shigellae and their drug resistance.
