近年来,国外分子生物学研究证实福氏志贺氏菌大毒性质粒编码的侵袭相关基因的表达受温度控制。当日平均气温持续在20℃或日最高气温持续在30℃以上时,菌痢等肠道传染病就会急剧上升〔1～3〕。本文旨在全市范围内进一步研究和证实菌痢发病与气温的关系,以便更有效地应用这一理论
In recent years, foreign molecular biology studies have confirmed that the expression of the invasion-related genes encoded by the Shigella flexnei plasmid is temperature-controlled. On the day when the average temperature continues at 20 ℃ or the maximum daily temperature above 30 ℃, intestinal diarrhea and other intestinal infectious diseases will rise sharply 〔1 ~ 3〕. This article aims to further study and confirm the relationship between the incidence of dysentery and temperature in the city in order to more effectively apply this theory
