AB M  catarrhalis  is  a  gram-negative  aerobic  coccus  morphologically  and  biochemically  similar  to  Neisseria.  It  causes  sinusitis,  bronchitis,  and  pneumonia.  Bacteremia  and  meningitis  have  also  been  reported  in  immunocompromised  patients.  The  organism  frequently  colonizes  the  respiratory  tract,  making  differentiation  of  colonization  from  infection  difficult.  If  M  catarrhalis  is  the  predominant  isolate,  therapy  is  directed  against  it.  M  catarrhalis  typically  produces  beta-lactamase  and  therefore  is  usually  resistant  to  ampicillin  and  amoxicillin.  It  is  susceptible  to  amoxicillin-clavulanate,  ampicillin-sulbactam,  trimethoprim-sulfamethoxazole,  ciprofloxacin,  and  second-  and  third-generation  cephalosporins.
