(not P. mirabilis), Plesiomonas shigelloides,Pasturella multocida, Pasturella pneumotropica, Streptococcus faecalis, andVibrio sp. sp.,
yes an organism can be MR & VP positive both. for example staphylococcus. __________________________________________________________________ M-R (Methly Red) is a test used primarily to identify gram-negative rods. M-R is a pH indicator that changes when the pH is below 4.5. The indicator will turn red below 4.5 and yellow, in a pH above that point. V-P (Voges-Proskauer) is a specific test for metabolic intermediates when sugars ferment to produce butylene glycol. This does occur is some gram negative rods. A positive V-P test is almost never observed with a positive M-R test. The M-R test is based on the production of sufficient acid to lower the pH to below 4.5. If some of the sugar being fermented is being used to make butylene glycol, then it cannot be used to also produce acids.
