Moraxella catarrhalis
What is Moraxella Catarrhalis?
Moraxella catarrhalis is a Gram-negative bacteria that is most commonly found in the upper respiratory tract of humans.
Moraxella catarrhalis is a normal inhabitant of the nose and throat, and is present in about 10 to 20 percent of healthy adults. It has been estimated that at least two out of five people carry it in their airways. However, for adults the bacteria may play a role in lower respiratory diseases.
What Are the Possible Symptoms of a Moraxella Catarrhalis Infection?
Symptoms of a Moraxella catarrhalis infection can vary depending on the affected area, but may include:
- Cough
- Shortness of breath
- Treble breathing
- Fever
- Flu-like symptoms
- Chest pain
How Is Moraxella Catarrhalis Diagnosed?
Moraxella catarrhalis can be identified by a laboratory culture of sputum, throat swab, or blood sample. It is usually only identified in cases where there is a significant infection, and other diagnostic tests may be used to properly diagnose the illness.
A sputum or throat swab sample can be cultured to determine the presence of the bacteria. The presence of antibodies in the blood can also be tested to confirm any suspicion of a Moraxella catarrhalis infection.
How Is Moraxella Catarrhalis Treated?
Treatment of a Moraxella catarrhalis infection typically involves antibiotics, such as amoxicillin, cefuroxime, ceftazidime, and macrolides. In some cases, antibiotics may be given intravenously. If antibiotics do not adequately treat the infection, then surgery may be needed to remove infected parts of the lungs.
It is important to complete all of the prescribed antibiotics, even if the symptoms improve before the course is finished. This will help to ensure that the infection is completely cleared from the body.
