J Clin Microbiol 1990; 28:2674. M. catarrhalis is an exclusively human pathogen, which emphasizes the importance of using human samples to elucidate the immune response to the bacterium. Several surface antigens of M. catarrhalis have been identified as targets of the human immune response, including UspA1, UspA2, CopB, TbpB (OMP B1), LbpB, OMP E, and lipooligosaccharide ( 2 - 5 , 7 , 8 , 16 , 34 , 42 ). An exacerbation caused by M. catarrhalis was defined by the onset of clinical symptoms simultaneous with the acquisition of a new strain [6, 14]. Bacterial Strains.

It can be cultured on blood and chocolate agar plates after an aerobic incubation at 37 °C for 24 hours. Cultures revealed gray-white hemispheric colonies about 1 mm in diameter. These colonies were fragile and easy to crumble, and appeared to have a waxy surface.

Moraxella catarrhalis outer membrane vesicles carry beta-lactamase and promote catarrhalis when first isolated in the early 1900s due to its morphology and certain On chocolate agar it forms small, opaque white colonies of 1-3mm in

Moraxella spp. are Gram-negative diplococci that morphologically and phenotypically resemble Neisseria spp.

Colonies of M. catarrhalis may have a rough surface and be friable in consistency, pinkish-brown in color, and opaque. Whereas Neisseria spp. have an optimal growth temperature of 35C-37C, M. catarrhalis strains tolerate lower temperatures and grow well at 28C.
