Which organism is differentiated from Micrococcus spp. using furazolidone susceptibility testing?

The differentiation of Staphylococcus spp. from Micrococcus spp. using furazolidone susceptibility testing is based on their distinct susceptibility patterns. Micrococcus spp. are typically susceptible to furazolidone, while Staphylococcus spp. are generally resistant. This characteristic allows for the differentiation between these two groups of bacteria in a laboratory setting.

In practice, the susceptibility of Micrococcus spp. to furazolidone suggests enzymatic activity that Staphylococcus spp. lack. Since this test is specifically looking at resistance or susceptibility to furazolidone, it serves as a key discriminative factor in identifying the two genera within clinical specimens.

Other options do not represent the same relationship when subjected to furazolidone testing. For instance, Streptococcus spp. do not share a similar susceptibility profile with Micrococcus spp. as they are typically classified differently and require other testing methods for identification. Pseudomonas spp. also differ significantly in their resistance mechanisms and testing criteria, and Bacillus spp. are generally not recognized within the same context as requiring differentiation from Micrococcus based on this specific susceptibility test. Therefore, Staphylococcus is correctly noted as the organism differentiated from Micrococcus spp. using furazolidone
