Moraxella catarrhalis ( M. Catarrhalis) is a type of bacteria that’s also known as Neisseria catarrhalis and Branhamella catarrhalis.It used to be considered a normal part of the human respiratory system, but more shows that can it sometimes causes infections.Many young children have M. Catarrhalis in their respiratory tract in the first few years of life, but it doesn’t always cause infections. When it does, it often results in a simple ear. In children with weakened immune systems, it can cause more serious infections, such as or bronchitis.Adults, on the other hand, usually don’t have M. Catarrhalis in their respiratory tract. When they do, they typically have a weakened immune system due to an underlying condition, such as an, or from treatment such as.Adults with lung conditions, especially and, are also more likely to develop an M.
Moraxella catarrhalis is a type of bacteria that can cause infections in children as well as adults who have weakened immune systems.
Catarrhalis infection. This is because chronic lung conditions make it harder for your lungs to clear out bacteria. Middle ear infectionM.

People with a lung disease who spend a lot of time in hospitals have the highest risk of developing pneumonia due to M. BronchitisBronchitis is an inflammation of the lungs that’s usually caused by a virus, not bacteria. However, in adults with weakened immune systems or chronic lung conditions, M. Catarrhalis can cause bronchitis. Like pneumonia, due to M.
Catarrhalis is most common in adults with lung conditions in hospitals.Both pneumonia and bronchitis produce similar symptoms, the main one being a cough that produces mucus and often lasts for weeks. However, the symptoms of pneumonia are usually more severe.
Sinus infectionM. Catarrhalis can also cause sinus infections in children as well as adults with weakened immune systems. Symptoms of a sinus infection are similar to, but tend to get worse over the course of a week rather than better.

Catarrhalis can cause pink eye in both children and newborns. MeningitisIn very rare cases, M. Catarrhalis can cause, especially in newborns. Meningitis refers to inflammation of the meninges, which are layers of tissue that surround the brain.
While most cases of meningitis are preventable with a vaccine, there’s no vaccine for M. Catarrhalis yet.
Infections caused by M. Catarrhalis usually respond well to antibiotics. However, almost all strains of M. Catarrhalis produce an enzyme called beta-lactamase, which makes them resistant to some common antibiotics, such as penicillin and ampicillin.Common antibiotics used to treat M.
Catarrhalis infections include:. amoxicillin-clavulanate.
trimethoprim-sulfamethoxazole (Bactrim). extended-spectrum cephalosporins, such as cefixime (Suprax). macrolides, such as (Zithromax)Adults can also take tetracycline and fluoroquinolone antibiotics.Regardless of which antibiotic you use, it’s very important to take them exactly as prescribed. Even if your symptoms start to improve and you don’t feel sick, make sure you complete the full course of antibiotics. Otherwise, your infection may return and be resistant to the original antibiotic used. Scientists are currently working to that protects against M. Catarrhalis infections.
This would be a major breakthrough in helping to prevent ear infections and pink eye in children. It will also be valuable for adults with COPD who are vulnerable to M. Catarrhalis infections.Until then, the best way to avoid M. Catarrhalis infections is to keep your immune system healthy through following a balanced diet and getting regular exercise.
