(Cosenza and Podgwaite 1966) Giammanco et al. Four independent isolates each of P. mirabilis, P. vulgaris, and Positive results for phenylalanine deaminase, urease, nitrates reduction, catalase, is biochemically similar to strains commonly identified as, , but esculin and salicin negative (only 2 strains of, Legend:  + positive 90-100%, - negative 90-100%, [+] positive 75-89%, [-] negative 75-89%, d positive 25-74% of strains, AMDG: Alpha-Methyl-D-Glucoside. Journal of Bacteriology, 1919, 4, 429-503. The bacteria that are able to completely lyse RBC will show visible clearing of the agar and is positive for beta hemolysis. Proteus mirabilis on Mac-Conkey Agar. Examine all inoculated plates at 48 and 72 h for amount of growth, colony size, pigmentation and hemolytic reactions. Oct 22, 2014 - This Pin was discovered by Aaron McLaughlin. Fig. All Rights Reserved. No filterable alpha haemolysin could be detected in P. mirabilis uropathogens provided from patients with urinary tract infections. https://catalog.hardydiagnostics.com/cp_prod/Content/hugo/Morganella.htm reactions. It is widely distributed in soil and water. Bile Esculin Agar. MacConkey Agar - Negative Lactose. They look like halos outlining the cells Species 4: Proteus mirabilis • Proteus mirabilis is a facultative anaerobic, highly motile, straight, Gram-negative rod. Large Gram Negative Rods. Pale white colonies as swarming growth with successive waves to form a thin sheer layer of concentric circles; swarming can be controlled by adding 0.1% boric acid. a) Salmonella enterica b) Escherichia coli c) Klebsiella pneumonia d) Proteus mirabilis. (2001) found that (85.14%) of Proteus isolates produce β-hemolysis, while other isolates produce α –hemolysis on blood agar plate [12][13][14]. Together with the results presented in the … Bile Esculin Agar Positive .
