General description

Nitrocefin is a chromogenic cephalosporin, it has a characteristic beta-lactam ring which on oxidation by beta-lactamase, renders nitrocefin from yellow to red in color. It is light-sensitive in nature and is quite expensive. It is used for the rapid detection of beta-lactamase enzymes in isolated colonies of Neisseria gonorrhoeae, Moraxella catarrhalis, Staphylococcus spp., Haemophilus influenzae and anaerobic bacteria.

Application

For the rapid detection of beta-lactamase enzymes in isolated colonies of Neisseria gonorrhoeae, Moraxella catarrhalis, Staphylococcus spp., Haemophilus influenzae and anaerobic bacteria.

All Neisseria gonorrhoeae strains contain multiple copies of integrated filamentous phage genomes with undefined structures. In this study, we sought to characterize the capsid proteins of filamentous N. gonorrhoeae bacteriophage NgoΦ6 and phagemids propagated in different bacteria. The data demonstrate

Microbes frequently rely on metabolites excreted by other bacterial species, but little is known about how this cross-feeding influences the effect of antibiotics. We hypothesized that when species rely on each other for essential metabolites, the minimum inhibitory concentration (MIC)
