​Infectious Diseases and Microbiology - Acute Diarrheal Disease ( Vibrio parahaemolyticus)
Vibrio parahaemolyticus-Induced Acute Diarrheal Disease

Para hemolyticus bacterium 
 Militaristic, halophilic, rod-shaped gram-negative bacteria.
Additionally, V parahaemolyticus is found in all coastal waters. 

Aetiology and Health Promotion 
Food poisoning from eating raw or undercooked seafood. Necessary infectious dosage is high. We did not find any carrier states or secondary transmissions.


Display of Clinical Signs 
 Constant, sudden, and intense cramping in the stomach region, accompanied by explosive, watery diarrhea. Symptoms often appear within a day after eating the tainted fish. Headache, chills, and low-grade fever are possible symptoms. Every illness eventually goes away on its own.
The development of illness The enterotoxin produced by V parahaemolyticus rarely leads to significant fluid loss in the intestines.
Compared to shigellosis, the damage that this vibrio causes to tissues is usually not as severe.


The consistency of diarrheal fluid is usually watery and occasionally mucoid. The diagnostic utility of a microscopic examination is low. While some individuals may have an abnormally high number of leukocytes and erythrocytes, the vast majority of the time these cell types are not noticeable. A conclusive diagnosis can be reached through biochemical testing and stool culture on TCBS agar.

Most patients do not need treatment. Both the clinical prevention course and the length of pathogen excretion are unaffected by antimicrobial therapy. As a precaution, make sure to cook fish properly and keep it refrigerated.
