Moraxella is a genus of gram-negative bacteria in the family Moraxellaceae. It is named after the Swiss ophthalmologist Victor Morax. The organisms are short rods, coccobacilli, or as in the case of Moraxella catarrhalis, diplococci in morphology, with asaccharolytic, oxidase -positive, and catalase -positive properties. Se hela listan på cdc.gov ous gram-negative diplococci were seen on the gram stain; a sample was considered appropriate only if it consisted of mate­ rial from the infected site [12]. All isolates were cultured on either 5% horse blood agar or chocolate agar.
