Food poisoning symptoms?

summary

Food poisoning refers to the acute toxic disease caused by the contamination of food by bacteria or bacterial toxins, or the presence of toxins in food. According to the etiology, there are different clinical manifestations. The patient's food is contaminated by bacteria or bacterial toxins, or the food contains toxins causing the disease. Food poisoning symptoms? Let's talk about it

Food poisoning symptoms?

1. Gastrointestinal food poisoning: gastrointestinal food poisoning is more common in summer and autumn when the temperature is higher and bacteria are easy to grow and reproduce in food. It is mainly characterized by nausea, vomiting, abdominal pain, diarrhea and other symptoms of acute gastroenteritis.

2. Vibrio parahaemolyticus food poisoning: acute and subacute diseases caused by eating food contaminated by Vibrio parahaemolyticus or food containing Vibrio parahaemolyticus. Vibrio parahaemolyticus is a common pathogen of food poisoning, which accounts for a large proportion of bacterial food poisoning. The main clinical symptoms are gastrointestinal symptoms, such as nausea, vomiting, abdominal pain, diarrhea and watery stool. The food poisoning caused by this bacterium has the common characteristics of outbreak onset (the same time, the same area, the same or similar symptoms, the same contaminated food), short incubation period (several hours to several days), and certain seasonality (summer and Autumn).

3. Proteus food poisoning: it is caused by ingesting a large amount of food contaminated by Proteus, which is a kind of food poisoning caused by conditional pathogenic bacteria. Proteus is a gram-negative bacterium, which can be divided into Proteus vulgaris and Proteus mirabilis according to different biochemical reactions. There are more than 100 serotypes. A large number of Proteus grow and propagate in human body, and produce enterotoxin, causing food poisoning. The incidence rate is high in summer and autumn, and the clinical manifestations are gastrointestinal and allergic.

matters needing attention

Blood culture of severe patients, take early and two weeks after the disease of double serum and culture the suspicious bacteria for serum agglutination test, double serum agglutination titer increase has diagnostic value. When suspected, especially those suspected of bacterial toxin poisoning, animal test can be done to detect the presence of bacterial toxin.
