Is aeromonas hydrophila a "cannibal bacteria"?

Aeromonas hydrophila is a gram-negative, rod-shaped heterophile bacterium mainly found in regions with a warm climate. This type of bacteria can have such extremely serious consequences that it is common to call it a "cannibal" bacteria.

1. What is aeromonas hydrophila?

Aeromonas hydrophila (AH) is a gram-negative bacterium, capable of causing serious diseases similar to other gram-negative bacteriums including vapor gangrene, Shigella, Salmonella, Escherichia coli, Pseudomonas aeruginosa … In terms of shape Aeromonas hydrophila bacteria are rod-shaped, about 0.5 – 1 micrometer in width and 1 – 3 micrometers in length.

In terms of habitat, Aeromonas hydrophila resides mainly in warm water and coastal brackish waters in hot and humid areas. They secrete toxins similar to Vibrio cholerae that cause cholera, so when infected, it will have an effect on the gastrointestinal tract and have clinical symptoms of mild cholera.

Aeromonas hydrophila bacteria are commonly present in fresh or dirty brackish water, muddy water or sewers… and causing diseases of shrimp, fish, frogs, frogs, reptiles is mainly; in cases where people are at high risk such as skin cuts, scratches, pimples, sores … if exposed to dirty water, there is a risk of infection.

2. Route of transmission of aeromonas hydrophila bacteria

If you drink dirty water with Aeromonas hydrophila or by their external toxins, after intestinal transit they can cause the risk of sepsis and multi-organ failure, which is often more likely to occur in the group of people who are immuno impaired.

If infected through the skin, Aeromonas hydrophila bacteria enter the wound causing necrotizing inflammation of the skin, muscle scales, muscles; causes sepsis, multi-organ failure with a high risk of death; at the same time can lead to a bile tract infection at risk of sepsis that is more likely to occur if the sufferer has a history of cirrhosis and is immuno impaired.

After penetrating the body through wounds on the skin, Aeromonas hydrophila bacteria enter the bloodstream, to soft tissues or bodies in the body, ingning and causing disease through the endocideal aerolysin. This toxins bind to a number of receptors at the host cell wall causing tissue damage and necrosis.

In order to make a definitive diagnosis caused by Aeromonas hydrophila, it is necessary to perform a disease culture test, isolate the bacteria or identify the bacteria using PCR (polymerase chain reaction).

3. Treatment and prevention of aeromonas hydrophila

3.1. Treatment of aeromonas hydrophila

  • Use of antibiotics: Aeromonas hydrophila bacteria can still be sensitive to common antibiotics such as sulfamides, chloramphenicol, tetracycline, ciprofloxacin …; however, they are still resistant to certain penicillin and cephalosporin antibiotics.
  • Use bactericidal chemicals: Aeromonas hydrophila bacteria are also easily destroyed by common bactericidal chemicals. In fact, although bacteria are sensitive to many antibiotics and easily destroyed with common bactericidal chemicals, due to the rapid development of the disease, sufferer is susceptible to necrotizing inflammation of many organizations and parts of the body so it is easy to lead to sepsis. , septic shock, multi-organ failure and often account for a high mortality rate.

Currently, with the help of modern resuscitation emergency vehicles and techniques with high response efficiency, it is possible to reduce deaths caused by Aeromonas hydrophila bacteria. However, it should be noted that after treatment from the disease, people who have been infected by Aeromonas hydrophila still suffer severe complications as a result of complications of the disease.

3.2. Prevention of diseases caused by aeromonas hydrophila

  • Do not or limit contact with dirty water sources especially when on the skin with wounds, cuts, abrasions, sores, pimples …
  • If the skin is damaged, it is necessary to cleanse the cuts, wounds that tear the skin, pimples and scratches … with soap and clean water; clean the lesion, let it dry, cover the wound with dry, clean bandages until healed
  • Deep or other serious wounds, it is necessary to go to a medical facility to treat the wound in accordance with regulations; in case of fungal infection in the legs must also be taken care of to avoid the risk of multiple infections of Aeromonas hydrophila bacteria.
  • Sanitation of domestic water environment, do not let water become contaminated or poisoned.
  • Perform good food hygiene and safety to prevent Aeromonas hydrophila bacteria from entering through the gastrointestinal tract.
  • Appropriate labor protection equipment should be used to protect workers who are regularly exposed to the water environment.
  • When there are signs of suspicion, it is necessary to go to a medical facility for early detection, blood transplantation is recommended and necessary tests are carried out to identify aeromonas hydrophila bacteria;
  • Make antibiotics for effective antibiotic treatment in the first place before it's too late.
