Plesiomonas bacteria are known to be gram negative and are rod shaped. Plesiomonas bacterium strains are water borne and are usually found in water bodies such as rivers, ponds and lakes. Bacterial strains can be acquired from coming in contact with raw shellfish. These bacterial strains have a tropical as well as sub tropical origin. The bacterial microorganisms are also found in contaminated water supplies. Infection occurs by ingestion or consumption of bacteria. On entering the host body, sometimes reaction does not occur immediately. The ingested Plesiomonas bacteria sometimes tend to reside as a temporal non infectious member in the body. Association with diarrhea and other virulent factors cannot be ruled out.
Symptoms and transmission
Plesiomonas bacteria are much associated with Gastroenteritis. Humans tend to acquire the bacteria and get infected through stool of patients suffering with diarrhea. Symptoms of an infection would range from fever, abdominal pain, nausea, chilly sensation, vomiting and diarrhea. These symptoms usually surface within twenty fours of bacteria ingestion. Ingestion of bacteria occurs either by the consumption of contaminated food, drinking or using contaminated water supplies or by coming in contact with the stool of an infected person. Diarrhea is characterized being watery, non bloody and non mucous in case of minor infections. But in case of a severe infection, diarrhea tends to be foamy, greenish yellow and may contain blood traces. The illness may continue for a week. A severe infection of Plesiomonas bacteria needs immediate medical attention and care.
The pathogenesis of the Plesiomonas bacteria is yet to be known. It is observed to be toxic as well as invasive. It is characterized as an intestinal pathogen because primarily it enters the human body on coming in contact with the stool of an infected person having diarrhea. Identification of the bacterial infection can be done by ordinary bacteriological analysis, sensitivity testing of antibiotics and serotyping. Infections from bacterial strains of the Plesiomonas bacteria occur in the summer months from contaminated water supplies and water bodies such rivers, ponds, sewage system etc. Transmission can be sporadic as well as epidemic. Epidemic infection occurs when ingestion of the bacteria occurs by consuming contaminated food or drinking contaminated water.
Absolute prevention of the disease is not possible; but you can prevent a possible infection by avoiding raw shellfish and consumption of contaminated food and water. Both children and adults are susceptible to contract or acquire an infection. The infected can be cured by prompt medical attention and by administering relevant antibiotics.
