The strains of cholera bacteria prevalent in China
In China's database of epidemic status, a painting depicted with the three epidemic waves documented in figures the status of cholera epidemic in the past 40 years throughout the country. Each time of fluctuations in the epidemic graph was related to the changes of cholera bacterial typing. The latest data of monitoring showed that the dominating bacterial type of cholera epidemics had another change emerging with a unique epidemic bacterial type. Specialists of the Chinese Center for Disease Control (CDC) warned that the possible aftermath of epidemic situation resulted from the changes of bacterial type of cholera must be dealt with intensive precaution.
Academician Gao Shouyi of Chinese CDC pointed out that the Inaba 1d strain emerged predominantly since last year, had the character of wide distribution of the same strain, and its 16S ribosomal gene probe hybridization belonged to the same strain seen in the majority of the provinces. In a certain location of the Southern provinces, the eltor strain, in addition to the occurrence of Inaba 1d strain, also partially emerged with the 1c, 1b, 1f strains; however, its ribosomal typing was identical with the predominant epidemic Inaba 1d strain, all came from the same clone line. In certain places of the southern west area the Ogawa type that mutated into Inaba type emerged; and the Inaba strain occurred in 2001 was not the continuation of the Inaba strain of 2000; additionally in another location of the south western area an Ogawa 6b unique epidemic strain occurred.
From 18-19 April, a working conference of national prevention and treatment of gastrointestinal infectious diseases was held in Beijing jointly sponsored by the Chinese CDC and the consultative committee of diarrhea specialists of Ministry of Health. The related specialists and the leading members of the CDC were organized to carry out an outspread discussion upon the subject of prevention and treatment of infectious diseases of the gastrointestinal tract, headed by cholera. In 17th April, the CDC issued notification to the CDC system throughout the country to carry out the weekly report of cholera epidemics and the acts of reports of the scattered cases; measures for augmentation of monitoring and retrieve of epidemic sources were also arranged., 百拇医药
