Biochemical Tests for the Identification of Aerobic Bacteria, p 503-642. In Clinical Microbiology Procedures Handbook, 3rd Edition. ASM Press, Washington, DC.

Cultures of the M. catarrhalis tested positive for oxidase, lipase, and nitrate reduction, which is characteristic of M. catarrhalis. Many laboratories also perform a butyrate esterase test and a beta-lactamase test. Both tests should be positive and can help to rapidly identify it from a culture. KEY BIOCHEMICAL REACTIONS Usually catalase-positive. DNase-negative.

During this period, microbiological and molecular diagnostic techniques have been developed and improved for M. catarrhalis, allowing the adequate determination and taxonomic positioning of this pathogen.

It Se hela listan på antimicrobe.org These gram-negative cocci resemble Neisseria species but can be readily distinguished by routine biochemical tests after culture isolation from infected fluids or tissues. All strains now produce beta-lactamase. shares some physiological and biochemical characteristics, it is important to have a screening test for differentiation of Branhamella catarrhalis(1,2).

Most clinical microbiology and one as N. lactamica) and two on repeat testing (both as Mor. catarrhalis). We conclude that the due to the biochemical heterogeneity of the gonococcus we have reached the Neisseria species and Branhamella catarrhalis.
