Methyl Red-Voges-Proskauer test(MR-VP)/ Acetoin Production Assay

Methyl Red-Voges-Proskauer test(MR-VP)/ Acetoin Production Assay Basic principle: Methyl red test The methyl-red test is used to detect the organism’s ability to produce sufficient acid from glucose fermentation and maintenance of the acidic environment (pH < 4.5) as shown by a colour change of the methyl-red indicator that is added at end of incubation of …

Levels of Disease Occurance: Epidemiology

Endemic: Usual frequency or constant presence of disease. Epidemic: More than usual frequency of occurance. Pandemic: Epidemic+ Widespread Sporadic: Occurs infrequently,haphazardly,irregularly or occasionally from time to time in a few isolated places withoud any pattern.
