Moraxella catarrhalis is a Gram-negative, aerobic, rod-shaped bacterium. It is a member of the family Moraxellaceae and is typically found in the normal human flora of the upper respiratory tract. It is also a common cause of otitis media, sinusitis, bronchitis, and other respiratory infections, as well as ocular infections.
Typical or Atypical?
Moraxella catarrhalis is typically considered a “typical” bacterium, meaning that it is typically found in the normal human flora of the upper respiratory tract and does not require special conditions to grow or thrive. It is also a common cause of otitis media, sinusitis, bronchitis, and other respiratory infections, as well as ocular infections.
Pathogenicity of Moraxella Catarrhalis
Moraxella catarrhalis is considered a “typical” bacterium, meaning that it is typically found in the normal human flora of the upper respiratory tract and does not require special conditions to grow or thrive. However, it is capable of causing opportunistic infections, especially in individuals with compromised immune systems or other underlying medical conditions. The most common infections caused by M. catarrhalis are otitis media, sinusitis, bronchitis, and other respiratory infections, as well as ocular infections.
Treatment of Moraxella Catarrhalis Infections
Moraxella catarrhalis infections can be treated with antibiotics, such as amoxicillin-clavulanate, cefixime, and ceftriaxone. In cases of severe or recurrent infections, treatment may also include the use of macrolides or quinolones. It is important to note that M. catarrhalis is becoming increasingly resistant to many antibiotics, so in cases of severe or recurrent infections, it is important to consult a physician for the most effective treatment.
