Does Moraxella catarrhalis need to be treated?

Moraxella catarrhalis is a bacterium that causes infection by sticking to a host cell. It does this using special proteins called adhesins that are on its outer membrane. Doctors usually treat M. catarrhalis infections with antibiotics, but this is becoming increasingly challenging due to antibiotic resistance.

How can you get Moraxella catarrhalis?

Adults with lung conditions, especially cystic fibrosis and chronic obstructive pulmonary disease (COPD), are also more likely to develop an M. catarrhalis infection. This is because chronic lung conditions make it harder for your lungs to clear out bacteria.

How do I get rid of Moraxella catarrhalis?

Amoxicillin-clavulanate, second- and third-generation oral cephalosporins, and trimethoprim-sulfamethoxazole (TMP-SMZ) are the most recommended agents. Alternatively, azithromycin or clarithromycin can be used. More than 90% of M catarrhalis strains have been shown to resist amoxicillin, and these rates vary by region.

Can Moraxella cause meningitis?

Moraxella sp. rarely cause invasive disease and only a handful of case reports exist implicating the organism as a cause of endocarditis, bacteraemia, septic arthritis, endophthalmitis and meningitis [3–8].

What are the symptoms of Moraxella catarrhalis?

catarrhalis otitis media, acute or chronic sinusitis, or pneumonia. In lower respiratory disease, patients have increased cough, purulent sputum production, and increased dyspnea.

How common is Moraxella catarrhalis?

Pathophysiology and Etiology Studies have shown that M catarrhalis colonizes the upper respiratory tract in 28-100% of humans in the first year of life. In adults, the colonization rate is 1-10.4%.

What is the best antibiotic for Moraxella catarrhalis?

Is Moraxella catarrhalis common in young children?

It is prevalent in the respiratory system in many young children, but it only becomes an issue if it causes infections. Although Moraxella catarrhalis is often present in young children, it can also affect adults, particularly those with underlying health conditions or a compromised immune system.

Can M catarrhalis cause pneumonia in children?

Many young children have this bacteria in their noses, and it can sometimes move into the middle ear, causing infection. Pneumonia is an infection in the lungs that’s often caused by bacteria. While M. catarrhalis typically doesn’t cause pneumonia, it can in adults with weakened immune systems or chronic lung diseases.

Is Mycoplasma catarrhalis normal in children?

It used to be considered a normal part of the human respiratory system, but more recent research 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.

Can Mycoplasma catarrhalis cause meningitis?

In very rare cases, M. catarrhalis can cause meningitis, especially in newborns. Meningitis refers to inflammation of the meninges, which are layers of tissue that surround the brain.
