What is Vibrio vulnificus? How scary is Marine Vibrio vulnificus?

Vibrio vulnificus.

I believe that most people should not have heard of it, let alone have an understanding of it, we will carry out a science popularization of it today, which can be interpreted literally as a bacterium in the ocean, known as the "silent killer in the ocean", marine fish, oysters, crabs, shellfish.

And whales. and so on these marine creatures.

It is possible to thin this bacterium, Vibrio vulnificus prefers a warmer environment, the most suitable living conditions are 37, when the temperature exceeds 20, they will multiply in large numbers, therefore, the human body temperature is very conducive to their reproduction. Once the human body is infected with this bacterium, they will multiply, and according to statistics, most cases die from multi-organ failure, with a case fatality rate of up to 75%.

The peak season for Vibrio vulnificus is in summer and autumn each year, when the sea temperature exceeds 20 degrees Celsius.

, Vibrio vulnificus is very active in its reproduction. They can infect humans in two ways, one is when the wound comes into contact with seawater, and there happens to be a large number of Vibrio vulnificus in the ocean, and it is worth noting that it can also cause infection when pricked by seafood carrying Vibrio vulnificus. Another way is to eat seafood that carries Vibrio vulnificus, especially raw food, which may also be targeted by the bacteria.

Although Vibrio vulnificus has the potential to be lethal and disabling, healthy people are not susceptible, and since the infection is usually not a big deal, there is alcoholism.

and chronic diseases, especially liver disease.

then Vibrio vulnificus infection is very dangerous. If you are a susceptible person, then before going to the beach for swimming, be sure to check your body for wounds, pay attention to the use of gloves when handling seafood, and try to use it after cooking it when eating seafood.

What should I do if I am targeted by Vibrio vulnificus? In fact, cases of marine Vibrio vulnificus infection in humans are relatively rare, but they are not uncommon, but the way to prevent them is not difficult. The first is to eat as little raw food as possible, and if you must eat it, try to keep it in the refrigerator for a while.

However, it should be said that marine life can also carry other bacteria or parasites.

So for the sake of health, try to cook it and eat it as much as possible. The second is not to touch seawater when there is a wound on the body. In addition, if you are pricked by seafood or objects that have come into contact with seafood during the process of handling seafood, it is best to rinse it with running water for 10 minutes.

If the wound comes into contact with seawater, or is pricked by seafood, then pay close attention to the changes in the wound in the next few hours, and if you find an abnormality, seek medical attention in time to avoid irreversible consequences as much as possible.

This is a bacterium in the ocean that can infect some animals in the ocean, which is called marine trauma orphanage. This kind of thing is quite scary, contains chemical properties, will produce a lot of toxicity, and will also affect the development of marine ecology.

This is a bacterium that grows in the ocean, and this bacterium can cause very serious harm to other marine life, easily cause various diseases, and easily lead to death.

This bacterium is particularly scary, it is a microbacterium that inhabits the ocean, and infection can cause organ failure very quickly.

There are two routes of infection with Vibrio marines: First, ingestion of foods containing marine Vibrio mushrooms, such as oysters, mussels, shrimp and crabs, and sashimi; The second is direct infection, such as being stabbed by seafood or touching contaminated seawater in the case of wounds on the hands and body, and the marine Vibrio will invade the body.

Many people have been stabbed by shrimp and crab and other seafood products, in fact, most people do not care and there are no accidents, there are two reasons, the first is that the stock of Vibrio vulnificus is relatively small, and most of the seafood usually encountered only carries a small amount of Vibrio vulnificus; The second is that everyone's immunity is different, so the response to pathogenic bacteria is also different. People with poor immunity, after receiving income generation, are of course more likely to be infected, and it is easier for Vibrio vulnificus to take advantage of the situation.

Prevention of Vibrio vulnificus in the ocean

1. Before eating seafood or aquatic products, it should be fully cooked and steamed thoroughly, because high temperature can kill bacteria; If you have diarrhea or vomiting, go to a regular medical institution for medical treatment in time.

2. When going to the beach to play in the water, or when eating raw seafood, you must take protective measures, especially those with poor liver function or body wounds, so as to avoid infection caused by Vibrio vulnificus; Wear gloves when handling seafood to prevent punctures.

3. Pay attention to personal hygiene, wash your hands before meals, ensure adequate sleep, and improve your own immunity.

The above content refers to Encyclopedia - Vibrio vulnificus.

There are two main routes of infection, one is the consumption of raw or uncooked shellfish (especially oysters), which is not harmful because it causes gastroenteritis, but because it causes cellulitis and sepsis, and the mortality rate is as high as more than 50%.

Another route of infection is through contact with seawater from broken limbs or stabbing from seafood**. The bacteria spread very quickly through broken ** and lead to severe myositis and myositis leading to severe gangrene followed by sepsis.

The turquoise sea has always been fascinating, and the sun, beach and waves seem to be one of the rare beauties in the world, and it is for this reason that many friends from the mainland will choose to see the ocean scenery on holidays. However, in recent years, there have been many social news reports of tourists who accidentally fell ill after stepping into the sea, and some even lost their lives after only a few days.

Perhaps this is inextricably linked to the "silent killer of the ocean" - Vibrio vulnificus. This bacterium inhabits the ocean, if the human body is infected, not only the onset is extremely fast, but also has a strong destructive power, and even statistics show that 75% of infected people will die within 48 hours due to organ failure if they are not in time.

Although this germ is so terrifying, many people still lack awareness of it due to its distance from the mainland, and knowing these 3 points may help you prevent it from happening.

1.Route of infection

As the name suggests, Vibrio vulnificus infections are mainly caused by direct contact with the sea, and can be found in offshore waters, bay waters and some seafloor sediments. According to analysis, this germ is more likely to survive in the environment of 37, which means that after entering the human body, it can obtain a more suitable living environment than seawater. If you have a wound on your body, or if you are punctured by a sharp object when you go to sea**, there is a certain probability that you will be infected with germs.

In addition, there is a risk of infection if you eat unpasteurised shellfish (e.g. oysters), so please be careful.

2.Susceptible population

Although Vibrio vulnificus is a big health threat, the healthy immunity of the human body is actually enough to strangle its infection in the cradle. Therefore, it is often the people who have certain problems with their body functions that are killed by germs. People with cirrhosis, long-term chronic diseases, and people with weakened immune systems are more likely to be infected with Vibrio vulnificus.

It is precisely because of this that such people need to pay special attention when they come into contact with the ocean and seafood, and also closely monitor their health after leaving the sea or eating, so as to avoid major accidents as much as possible.

3.Prevention and control methods

Bacterial infections are mostly caused by self-neglect, so increasing awareness of the protection of marine Vibrio vulnificus can reduce the risk of infection. Common methods include checking the wound before going to sea, and if there are unhealed wounds on the body, pay attention to strict waterproofing; Ensure high temperature sterilization when cooking seafood products, and reduce the use of raw and cold eating methods such as sashimi; When playing and fishing in the ocean, pay attention to the protection of feet, hands and other direct contact parts, and it is best to wear shoes and gloves to avoid accidental punctures.

If you are really "unlucky", don't panic too much. After the wound occurs, the wound should be cleaned immediately with alcohol or other medicines that can be disinfected, and the antibiotics should be inoculated in a nearby hospital in time to achieve the effect of antibacterial and sterilization.

In short, although the ocean is beautiful and magnificent, don't relax your control over health and safety, and take protective measures to undoubtedly make a trip to the beach safer and more fulfilling.

In the near future, everyone likes to run to the beach, but if you are injured in an accident, you should pay more attention! If you accidentally get infected with Vibrio marine, it can even be life-threatening. Doctors remind that if the infection is not timely, it is necessary to amputate the limb to prevent the infection from spreading throughout the body.

Hong Bobin, director of the emergency infection department of Taipei Tzu Chi Hospital, said that ** is the largest organ in the human body, which is divided into three parts from superficial to deep: epidermis, dermis, and subcutaneous tissue. It can resist the invasion of germs into the body, and also has the function of regulating body heat and producing vitamin D under sunlight.

If the inflammation invades the dermis and subcutaneous tissue due to bacterial or viral infection, it is the cellulitis that is heard from time to time, Hong Bobin pointed out that severe cellulitis may deteriorate into necrotizing fasciitis in a short period of time.

When bacteria invade the deep fascia and spread rapidly along the gap between the fascia and the subcutaneous tissue, the small blood vessels in it will be blocked by the inflammation of the plug, resulting in tissue ischemia and necrosis, which is necrotizing fasciitis, which can occur in all parts of the body, but the lower limbs are the most common. 」

The incidence of necrotizing fasciitis is between 100,000 people per 100,000 population, and it is more likely to occur in people with diabetes, liver cirrhosis, or people who need to take steroids for a long time. 」

The most common bacteria that cause infection are Vibrio vulnificus (also known as Vibrio vulnificus) in seawater, Aeromonas hydrophilia (Aeromonas hydrophilia) in freshwater, and Streptocous pyogenes (group A streptococcus).

For example, a 58-year-old Mr. Huang with a history of liver cirrhosis recently went to a beach with his family in June and accidentally kicked a sharp stone on the side of the road, causing bruises and broken skin. Mr. Huang was unimpressed at the time, but on his way home in the evening, he suffered severe leg swelling and pain, fever and discomfort, and confusion, and was taken to the hospital. The emergency physician diagnosed Vibrio marine infection, which has invaded to the depths of **, causing necrotizing fasciitis.

The physician examines the pathogen through a medical history, blood tests, and microbial cultures. **, one or more debridement surgeries can be performed by the surgeon to block the inflammatory response by removing the necrotic tissue, and at the same time antibiotics** This explosive infection.

Hung reminded the public that in addition to bathing beaches, eating undercooked seafood and fish in the shell may also be infected if they are stabbed by them. People with the above-mentioned predisposition or chronic diseases should consider their own resistance and avoid exposure to dangerous areas where bacteria can breed.

The course of necrotizing fasciitis changes rapidly, and the tissue can die severely within a few hours, and it is important to seek medical attention as soon as possible if symptoms of suspected infection such as fever, chills, redness, swelling, heat and pain in the affected area appear.

Dead seafood does not have to carry Vibrio vulnificus.

But Vibrio vulnificus is indeed terrifying.

Vibrio vulnificus is a type of bacteria that inhabits the ocean and is known as the silent killer of the ocean, and can be carried by marine organisms such as marine fish, oysters, crabs, shellfish, and whales. March to November is the best season for the growth and reproduction of Vibrio vulnificus. Infection with the bacterium has a rapid onset and rapid progression, with most cases dying from multi-organ failure, with a mortality rate of up to 75%.

People are infected with this bacterium, and the disease progresses rapidly, and the consequences are terrible.
