Prevalence and emerging resistance of Moraxella catarrhalis in lower respiratory tract Neisseria catarrhalis, or Branhamella catarrhalis is a gram-negative, aerobic, Other tests used to identify the organism were oxidase test, cat

Info. Shopping. Tap to unmute. If playback doesn't begin The speed and precision of hydrolysis of tributyrin to butyric acid as a test to detect Branhamella catarrhalis were evaluated. The test proved consistently reliable in the identification of strains and correctly differentiated B catarrhalis from Neisseria sp.

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. This Moraxella (Branhamella) catarrhalis 25238 No color change after inverting tube Limitations of Test 1. It has been reported that some strains of N. gonorrhoeae may produce a false negative result with Gonochek®-II when isolated on certain selective media, such as Improved Thayer-Martin. If the Positive results for alkaline phosphatase, catalase, esterase, lipase, extracellular deoxyribonuclease, oxidase, tributyrin hydrolysis & nitrate reduction. Negative results for acid phosphatase, citrate utilization, gelatin liquefaction, urea hydrolysis, hydrogen sulfide, indole production, phenylalanine deamination, Tween 80 hydrolysis.

An isolate was almost certainly not a gonococcus if it gave a negative superoxol test result, as all but one of 596 available gonococci gave positive test results. Branhamella catarrhalis, previously named Neisseria catarrhalis was known as a saprophytic inhabitant of the human respiratory tract.

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). B. catarrhalis appeared as Gram-negative cocci in white colonies which were oxidase- and catalase-positive and which did not produce acidification of sugars.
