It can be criticized at any age. In recent years, the disease occurring in the tropics has been classified as "infectious malabsorption", and the disease is divided into parasitic (ie, giardiasis) and non-parasitic (tropical inflammatory diarrhea). Kind. basic knowledge Sickness ratio: 0.05%-0.07% Susceptible people: good for tropical residents Mode of infection: non-infectious Complications: anemia

Causes of tropical inflammatory diarrhea

It is believed that chronic intestinal infections, which may be caused by one or more pathogenic microorganisms or parasites, are not clearly related to the diet of the wheat gelatin. The disease is epidemic, seasonal, and broad-spectrum antibiotics are effective, but feces, intestinal contents and No pathogenic bacteria were found in the intestinal mucosa, and nutrient deficiencies such as protein, vitamin B, and folic acid may be related to the onset of the disease, but it is not an important cause.

Intestinal mucosa villi deformed irregularly, coarse or flattened; tongue-shaped, ridged or flat, curly, jejunal mucosa biopsy has a long glandular fossa, nuclei cell nuclear hypertrophy, argyrophilia, epithelial cells are square or Flat shape, goblet cells decreased, epithelial cell enzyme activity decreased, electron microscopic examination showed irregular microvilli, agglomeration of the group, microsomes and mitochondria increased, some of them also had superficial or atrophic gastritis.

Tropical mouth inflammatory diarrhea prevention
