Long, thin, slowly growing, oxidase-positive, catalase-positive gram-negative rods that do not grow on MacConkey agar should suggest DF-2. Although testing of antimicrobial susceptibility is problematic, DF-2 has been found to be resistant to aminoglycosides. The drug of choice is penicillin....

Penicillin-Susceptible, Oxidase-Negative, Nonhemolytic, Nonmotile Bacillus megaterium in Disguise of Bacillus anthracis * For large Gram-positive rods (Lactobacillus morphotypes), the scoring was reversed with their absence scored as 4, fewer than 1 per OIF scored 3; a count of 1-5 per OIF scor...
The Enterobacteriaceae are Gram-negative rod-shaped bacteria, which are typically motile by virtue of peritrichous flagella and are non-sporing, facultative anaerobes, which will grow in the presence of bile salts. They are oxidase negative, catalase positive, reduce nitrate, and, almost all, ...
So what were the properties of this cell's wall? Was it Gram-positive or Gram-negative? And was it a coccus or a rod? 展开 关键词: Were Gram-positive rods the first bacteria?, Artículo DOI: 10.1016/S0966-842X(03)00063-5 被引量: 99 年份: 2003 ...
Gram-negative cocci appear pink after a Gram stain procedure because the purple primary dye, crystal violet, is washed out, allowing the red/pink counterstain, safranin, to be visible. Are cocci Gram-negative or Gram-positive? Cocci are round shaped bacteria. They can be Gram-positive or Gram...
All these organisms are aerobic, oxidase-positive, motile, gram-negative bacilli that can be isolated in the laboratory on blood or chocolate agar; most but not all strains also grow on MacConkey agar. Some isolates produce a yellow or tan-brown pigment. Comamonadaceae. Current ...
His sputum sample yielded a weakly oxidase-positive, gram-negative rod, that was gentamicin and colistin resistant and was reported as Pseudomonas spp. He was given anti-pseudomonas antibiotics but recovered slowly. Since then he had several exarcerbations with gram-negative rods that were reported...
This test is used to identify microorganisms containing the enzyme cytochrome oxidase (important in the electron transport chain). It is commonly used to distinguish between oxidase negative Enterobacteriaceae and oxidase positive Pseudomadaceae.
