Acinetobacter lwoffii, also known as Mima polymorpha or Acinetobacter calcoaceticus var. lwoffii, is a Gram-negative bacillus bacterium from the genus Acinetobacter.

Acinetobacter is a bacteria that is resistant to a wide range of antibiotics.

Natural Environment for Acinetobacter Iwoffii

It is commonly found in wet environments such as:

  1. Soil and mud
  2. Ponds
  3. Wetlands
  4. Wastewater
  5. Fish farms
  6. Seawater

Acinetobacter bacteria can be carried on the skin of healthy people, especially if they work in a healthcare setting. It can survive on dry surfaces for long periods of time, making it difficult to eradicate.

Acinetobacter bacteria of all types can cause infections in humans. Learn more about Acinetobacter infections, including symptoms, risk factors, and more, in this article.

Infection and Symptoms

Acinetobacter strains can cause a variety of infections in humans, including;

  1. Blood infections
  2. Urinary tract infections
  3. Pneumonia, an infection of the lungs
  4. Infections in wounds

Symptoms will vary depending on the type of infection caused by the bacteria. For each type of infection, people may experience the following symptoms.

  • Blood infection:

  1. Chills
  2.  Vomiting
  3. Confusion
  4. Fever

    ° Urinary tract infection:

  1.  Frequent need to urinate
  2.  Pain or burning sensation when                 urinating.
  3. Blood in the urine
  4. Cloudy urine
  5. Foul smelling urine

    ° Pneumonia:

  1. Fever
  2. Chills
  3. Coughing
  • Wound infection:

  1. Redness and pus in or around the wound
  2. Fever
  3. Pain around the wound

Acinetobacter infection symptoms can appear anywhere between 4 and 40 days after a person comes into contact with the bacteria, but they usually appear within 12 days.

Acinetobacter infection does not always result in symptoms. A person can also carry bacteria in and on their body without getting sick.

Types of Acinetobacter Bacteria

Types of Acinetobacter spp. include;

1. Acinetobacter baumannii:

Acinetobacter baumannii is the species responsible for roughly 80% of Acinetobacter infections in humans.

Other bacteria that commonly cause infections include;

2. Acinetobacter calcoaceticus 

3.  Acinetobacter lwoffii.

Researchers discovered the aforementioned Acinetobacter species, as well as a few others, on vegetables, dairy products, meat, livestock, and human skin. This finding suggests that humans can come into contact with Acinetobacter bacteria in a variety of ways.

These Acinetobacter strains are all resistant to antibiotics.

Treatment for Infections caused by Acinetobacter Iwoffii 

Because Acinetobacter strains are frequently resistant to many commonly prescribed antibiotics, a doctor will determine which treatment is best in each case.

In a laboratory, a doctor will test the Acinetobacter bacteria that is causing the infection. This will allow him to determine which antibiotics may be effective in combating it.

He will select an antibiotic that is effective against the bacteria while also considering any potential side effects. He will also consider whether antibiotics will interfere with any other medications a person is currently taking.

The majority of Acinetobacter bacteria are resistant to almost all antibiotics, including a powerful class of antibiotics known as carbapenems.

If you have this type of Acinetobacter infection, your doctor may refer to you as having carbapenem-resistant Acinetobacter (CRAB).

To treat the infection, he may prescribe other antibiotics, such as beta-lactam antibiotics or antimicrobial drugs. Researchers are also looking into new antibiotics that could be used as a treatment option in the future.

Prevention

Proper hygiene and thorough cleaning of medical equipment and healthcare environments can aid in the prevention of Acinetobacter infections.

Healthcare workers and patients should take the following precautions:

  1. Taking antibiotics only when necessary and exactly as prescribed by a doctor.
  2. Daily cleaning of hospital rooms and facilities.
  3. Thoroughly clean medical equipment and surfaces.
  4. When treating someone with an Acinetobacter infection, use gowns and gloves.
  5. Hand washing is also very important in helping to prevent Acinetobacter infections.

People should remember to wash their hands:

  1. Prior to preparing or eating food
  2. Following the use of the restroom.
  3. Before you touch your mouth, nose, or eyes.
  4. Before and after using any medical equipment, particularly enteral tubes and catheters.
  5. Before and after wound dressing or bandaging.
  6. Following a cough, sneeze, or nose blow.
  7. Following contact with surfaces in healthcare facilities such as doorknobs and bedside tables
  8. After interacting with phones or remote controls.
  9. People can use soap and warm water to wash their hands, or they can use an alcohol-based hand sanitizer.

Acinetobacter Iwoffii Infection Transmission

The use of medical equipment such as ventilators and catheters, as well as antibiotic treatments, has increased the number and severity of Acinetobacter infections.

Acinetobacter infections are most common in intensive care units.

Acinetobacter infections are most common in people who work or receive treatment in healthcare settings such as hospitals.

Acinetobacter bacteria can survive on surfaces and equipment in healthcare settings for long periods of time. People can spread bacteria to others by using dirty hands, surfaces, or medical equipment.

Factors Increasing the risk of Acinetobacter infections

  1. Immune system deficiency (weakness of the immune system)
  2. Chronic lung diseases
  3. Diabetes
  4. Using a Ventilator
  5. Using Catheters 
  6. Surgical wounds that are still open
  7. Being under intensive care
  8. Long-term hospitalization

Acinetobacter infections are extremely unlikely in healthy people. Acinetobacter infections, on the other hand, can be fatal in critically ill people.

Summary 

Acinetobacter is a type of bacteria found in the environment that can live on human skin. Infections can occur if bacteria enter the body.

Some Acinetobacter strains cause blood, lung, and urinary tract infections.

Acinetobacter infections are uncommon in most healthy people. However, the use of catheters and ventilators can raise the risk. People in intensive care or with chronic health conditions are also more vulnerable.

Because many types of Acinetobacter are resistant to some antibiotics, the type of treatment will vary depending on the individual case.
