What is the cause of bacillary dysentery?

Bacillary dysentery is an intestinal infectious disease caused by dysentery bacilli, mainly transmitted through the digestive tract, summer and autumn, children and young adults, patients and carriers are the main source of infection. Bacillary dysentery is an intestinal infectious disease caused by dysentery bacilli, mainly transmitted through the digestive tract. The following is a detailed analysis of the causes of bacillary dysentery: 1. Pathogens: Shigella spp., a member of the Enterobacteriaceae family, has four serogroups (A, B, C, D) and more than 40 serotypes. Source of infection: patients and carriers are the main sources of infection, mild patients discharge less bacteria, easy to be ignored. 2. Transmission route: digestive tract transmission: Dysentery bacilli are excreted with the feces of patients or carriers, transmitted indirectly through contaminated hands, food, water or life contact, or flies, cockroaches, etc., and enter the digestive tract through the mouth. Susceptibility: The population is generally susceptible, and certain immunity can be obtained after infection, but there is no cross immunity between different types of Dysentery bacilli. 3. Epidemic characteristics: summer and autumn: High temperature and humidity are conducive to the reproduction and transmission of dysentery bacilli. Children and young adults are more frequent: living habits, sanitary conditions and other factors. Dispersion is dominant: outbreaks caused by contaminated food and water are more common. In short, bacillary dysentery is a preventable and treatable disease, pay attention to food hygiene, develop good hygiene habits, strengthen water management and harmless treatment of feces and other measures, can effectively prevent and control the occurrence and epidemic of this disease.
