Causes of bacterial dysentery

Bacillary dysentery is caused by Shigella spp. and spread via the fecal-oral route. Decreased immunity, poor hygiene and eating habits, and environmental factors can also increase the risk of infection. Bacillary dysentery is an intestinal infection caused by Shigella spp., which is mainly transmitted via the fecal-oral route. The following is a detailed analysis of the causes of bacillary dysentery: 1. Pathogenic bacteria infected with bacillary dysentery are mainly Shigella, including Shigella, Bacillus flexneri, Bacillus boisei and Bacillus sonnei. These pathogenic bacteria are transmitted through contaminated food, water or daily life contact, and enter the human body through hand-mouth route. After ingestion of food or water containing pathogens, pathogens multiply in the intestine and release toxins, resulting in intestinal inflammation and pathology.2. Human immunity The human immune system plays an important role in resisting pathogenic infections. Under normal circumstances, the immune system can recognize and eliminate pathogens to prevent infection. However, in some cases, the body's immunity may be reduced, making it easier for pathogens to infect and reproduce. For example, people with an inadequate immune system, long-term use of immunosuppressants, and other diseases are more susceptible to bacterial dysentery. 3. Sanitary conditions and eating habits Good hygiene habits and dietary hygiene are important measures to prevent bacterial dysentery. Unclean food and water intake is one of the main causes of infection. In addition, poor personal hygiene practices, such as frequent hand washing, can also contribute to the spread of pathogens. Dietary habits can also affect the risk of infection, such as eating raw meat, undercooked food, or drinking unsterilized water. 4. Environmental factors Certain environmental conditions can also facilitate the spread and survival of pathogens. For example, the incidence of bacillary dysentery may be higher in areas with poor sanitation and polluted water sources. Climate change and seasonal factors may also affect the transmission of pathogens. In summary, the main causes of bacillary dysentery include pathogen infection, decreased immunity, poor sanitation and dietary habits, and environmental factors. The key to preventing bacillary dysentery is to maintain good personal hygiene, pay attention to food hygiene, strengthen environmental hygiene and personal protection. If symptoms are suspected, seek medical attention promptly and follow the doctor's treatment advice.

For high-risk groups, such as children, the elderly and immunocompromised persons, special attention should be paid to prevention and protection.
