From a public health and risk assessment standpoint, microbial pathogen assays based on infectious units are the most relevant and interpretable ones
e.g., enterohemorrhagic strains of Escherichia coli (O157:H7): culturing from water a challenge; many other, non-pathogenic strains of E. coli.
Right: positive (color change)
Efforts to improve culture and reduce or eliminate non-target bacteria:
Inability of typical culture methods now in use to detect or distinguish:
(there is disagreement on this point)
Virus plaques in a cell layer overlaid with agar medium and stained with a vital dye
Infected Cell Culture with CPE
Uninfected Cell Culture
Estimating Viral Dose:Relationship of Infectivity to Virus Particle Count
Environmental forms of some protozoan parasites, such as spores and oocysts, are culturable in susceptible host cells
C. parvum Oocysts
Immunofocus of Living Stages: in MDCK Cells with C3C3-FITC Antibody
Examples of Stand-off/DTW Systems:
