1、志贺氏菌的抗药性研究,标题,Antimicrobial resistance of Shigella spp.from humans in Shanghai,China,200420112004年2011年在中国上海对志贺氏菌抗药性的研究,Abstract,A retrospective study conducted on patients with diarrhea in Shanghai,China from 20042011,indicated thatof 77,600 samples collected,1,635(2.1%)tested positive for Shigella
2、.Species isolated included S.sonnei(1,066,65.1%),S.exneri(569,34.7%),and S.boydii(3,0.2%).Most of the Shigella isolates were found to be resistant tostreptomycin(98.7%),trimethoprim(98.0%),ampicillin(92.1%),and nalidixic acid(91.7%).Additionally,many isolates were resistant to tetracycline(86.9%),tr
3、imethoprim+sulfamethoxazole(80.1%),sul soxazole(76.8%)and gentamicin(55.5%).Approximately 80%of the isolates were resistant to at least eightantimicrobial agents,14%to at least ten antimicrobials tested and 10 isolates to fourteen antimicrobials,including sulfonamides,uoroquinolones,tetracyclines,am
