The specificity of bacteriophages for bacterial cells makes it useful for the typing of bacterial strains and the detection of pathogenic bacteria. Phage typing is also known as the use of sensitivity patterns to specific phages to accurately identify microbial strains. The sensitivity of the detection will be increased,if the specific antibody detects the phage that binds to the bacteria. For the detection of unknown bacterial species, different phages are set on the lawn. If plaques (transparent areas) appear, it means that the phages have grown and lysed the bacteria, making it easy to identify specific bacterial species. There are certainly other methods that can be used to detect pathogens, such as the use of bacteriophages, which can specifically deliver reporter genes or use the green fluorescent protein that is expressed after bacterial infection. Similarly, a phage with a fluorescent dye covalently attached to its coating can be used to detect specific adsorption. It is also possible to detect some released components, such as adenylate kinase after specific lysis of bacteria, and antibodies and peptides displayed by phage, which will specifically bind toxins and bacterial pathogens.

(Kirchhelle C, 2020)Creative Biolabs provides some of the most comprehensive services in the world to detect the presence of bacteriophages and prophages in various bacterial hosts. As a phage professional laboratory and world expert, with access to a complete phage array, Creative Biolabs is particularly suitable for performing phage typing which is used phage to identify bacterial strains and track the source of bacterial infection or pollution outbreaks. Our services are listed as following, but are not limited to:
We use dual phage technology to detect the binding of antibodies to specific antigens. Phage amplification test can also be used to detect pathogens. This technology is most widely used to detect Mycobacterium tuberculosis, E.coli, Pseudomonas, Salmonella, Listeria and Campylobacter.
