The colonies were confirmed using Gram staining and biochemical tests for catalase, oxidase, DNAse, and butyrate esterase production (Remel™ catarrhalis test disc). This tributyrin spot test helped in differentiating M. catarrhalis from other nonpathogenic Neisseria species that are generally found in the respiratory tract.

Vaneechoutte andco-workers (11) recently reported a rapid tributyrin hydrolysis test that used 4 SUMMARY Moraxella catarrhalis (formerly known as Branhamella catarrhalis) has emerged as a significant bacterial pathogen of humans over the past two decades. 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. Over the same period, studies Thetestis rapid,simple,andeasytoperform.Thebutyrate esterase spot test was useful for direct identification of M. catarrhalis from primary cultures. However, false-positive reactions mayoccurwith mixedcultures.

The combination of Gram stain, oxidase, and catalase tests to tributyrin hydrolysis provides a means of positive same day identification of B catarrhalis. In tests of 728 cultures, including 460 N. gonorrhoeae, 4 Neisseria lactamica, 257 Neisseria meningitidis, and 7 Branhamella catarrhalis, both Superoxol (30% H2O2; J. T. Baker Chemical Co., Phillipsburg, N.J.) and amylase inhibition tests were 100% sensitive (positive) for 20-h cultures of N. gonorrhoeae. Moraxella (Branhamella) catarrhalis. Moraxella catarrhalis (MC) is the third ranking commensal inhabitant of the upper respiratory tract (Chung et al., 1994) capable of inducing otitis media, sinusitis, conjunctivitis, and bronchitis in pediatric populations (Bakaletz et al., 1995; Luke et al., 2007). m.catarrhalis identification, tests for the identification of Moraxella catarrhalis Elle doit être mise en évidence par rapprochement des disques ou par la réalisation du test de synergie sur gélose MH +250µg.mL-1 de cloxacilline qui inhibe la céphalosporinase.

catarrhalis strains within 30 minafter inoculation. A total of 74 clinical isolates of Branhamella catarrhalis were characterized with respect to their ampicillin, amoxicillin-clavulanate, cephalothin, cefaclor, erythromycin, tetracycline, chloramphenicol, and trimethoprim-sulfamethoxazole MICs and zones of inhibition. Disk diffusion tests were perfo … Se hela listan på catalog.hardydiagnostics.com tion tests. M. catarrhalis was the commonest isolate and was considered to be a significant pathogen. However, a study on gram-negative cocci in the common cold and influenza by Gordon in 1921 [7] described M. catarrhalis as a saprophyte of negligible virulence found in the throat of healthy adults.

Branhamella catarrhalis has long been One hundred and fifty three strains were tested by Gram stain, catalase, oxidase, Branhamella catarrhalis: an organism gaining respect as a pathogen. used for the presumptive identification of Moraxella (Branhamella) catarrhalis. Catalase test: The catalase test is used to differentiate some bacterial species The combination of Gram stain, oxidase, and catalase tests to tributyrin hydrolysis provides a means of positive same day identification of B catarrhalis. La identificación de B. catarrhalis está basada lis de las otras especies de Branhamella (B.

Catalase Test (Reaction with 3% hydrogen peroxide) When performed on a clear base medium without hemoglobin, the catalase reaction of M. catarrhalis may occur vigorously, but very rapidly and then become “negative;” persistent bubbles may not be observed. Thus, the reaction should be watched to observe a positive catalase reaction. Catalase

It should be noted that strains of N. ovis have occasionally been isolated from humans. 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. MORAXELLA (SUBGENUS - BRANHAMELLA) 27 plus species including: SPECIES Moraxella atlantae Moraxella bovis Moraxella ( Branhamella ) catarrhalis Typically positive results with Moraxella catarrhalis: The oxidase test; The catalase test; Tributyrin hydrolysis; Typically negative results with Moraxella catarrhalis: Acid from glucose; Acid from maltose; Acid from fructose; Acid from sucrose; γ (gamma)-glutamylaminopeptidase; Polysaccharide synthesis A total of 176 strains identified as Branhamella catarrhalis were isolated from various clinical specimens, mainly sputum (71), pharynx (49), eye (24), nose (11), ear (6) and tracheal aspirate (7).
