Seasonal biorhythms with the intermittent periods of activity and rest in the manifestation of the enteropathogenic properties of cholera and NAG vibrios have been revealed. In the climatic conditions of the Rostov region the period of maximum activity in respect of this characteristic is shown to fall on spring and summer, while the period to rest is shown to fall on autumn and winter. In highly toxigenic cultures the phase of rest has been found to be considerably shorter than in cultures with low toxigenicity. The cyclic changes in the toxin-producing function of vibrios are suggested to be the main reason of the seasonal character of infections caused by cholera and NAG vibrios.
已发现霍乱弧菌和非典型致泻弧菌致病特性表现中的季节性生物节律，其具有活动和休息的间歇性周期。在罗斯托夫地区的气候条件下，就这一特性而言，最大活动期出现在春季和夏季，而休息期则出现在秋季和冬季。已发现高产毒培养物中的休息期比低产毒培养物中的休息期短得多。弧菌产毒功能的周期性变化被认为是霍乱弧菌和非典型致泻弧菌引起感染具有季节性特征的主要原因。
