M. catarrhalis is a frequent cause of. Otitis media in children. These gram-negative cocci resemble Neisseria species but can be readily distinguished by routine biochemical tests after culture isolation from infected fluids or tissues. 2019-01-29 A total of 756 strains representing 17 Neisseria spp.

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.

Table 1 provides a list of traditional tests used to identify strains of N. gonorrhoeae. Detailed information on biochemical tests is in the menu at left and in Table 1. Table 1. Differential characteristics of human Neisseria spp., M. catarrhalis, and K. denitrificans

It can differentiate Bcatarrhalis from Nperflava, Npharyngis and several other non-pathogenic Neisseria spp (table). In a previous study Young etal'2 foundthat 128of133 isolatesofNmeningitidis were superoxol negative. The superoxol Eikenella corrodens, Kingella spp., and Cardiobacterium hominis, produced unique biochemical reaction patterns on the panel. Modification of interpretative criteria for certain tests, expansion of the data base to includeotherspecies, andsuggestionsfor additional confirmatory tests will increasetheaccuracy andutility of the HNIDpanel.
