Abstract

Incubation of Vibrio cholerae of O-group serotype 1 with chitin particles resulted in adsorption of vibrios onto chitin; chitin-adsorbed V. cholerae survived exposure to acid better than nonadsorbed vibrios. V. cholerae multiplied in dialyzed chitin suspended in 4.2% NaCl, suggesting that adherence to ingested chitin of crustacea might be of epidemiological significance by providing a substrate for vibrio multiplication as well as protection from gastric acid during stomach transit.

摘要

将O群血清型1的霍乱弧菌与几丁质颗粒一起培养,会导致霍乱弧菌吸附到几丁质上;吸附在几丁质上的霍乱弧菌在暴露于酸环境时比未吸附的霍乱弧菌存活得更好。霍乱弧菌在悬浮于4.2%氯化钠中的透析几丁质中繁殖,这表明,附着在摄入的甲壳类几丁质上,可能通过为霍乱弧菌繁殖提供底物以及在胃内转运期间保护其免受胃酸影响而具有流行病学意义。
