Article Abstract:
The SYTOX Green stain is a high-affinity nucleic acid stain developed for use in bacterial viability assessments. It is able to penetrate cells with compromised membranes but is unable to penetrate membranes of live cells. This characteristic makes it a viable dead cell indicator. This stain was then used in the flow cytometric detection of dead Escherichia coli and Salmonella typhimurium within starved populations in order to test its efficacy. Results show that the stain's use is problematic because it underestimated the fraction of dead cells in the population.

Article Abstract:
Monoclonal antibodies (MAbs) are produced that are directed against the major outer membrane protein (MOMP) of Campylobacter jejuni by using recombinant major outer membrane protein (MOMP) as the antigen. The epitope is located in a region that is exposed to the periplasm and MAb5C4 is shown to be a potentially specific and sensitive MAb that is used for the specific detection and identification of Campylobacter jejuni.

Article Abstract:
The use of a solid-phase cytometer was described to detect and enumerate the toxic alga Prymnesium parvum in natural samples, using a specific monoclonal antibody and indirect immunofluorescence. It was observed that solid-phase cytometer could be used to rapidly enumerate natural P. parvum cells and detection of other toxic algae, with an appropriate antibody or DNA probe.
