Vibrio Phage Reference Laboratory, National Institute of Cholera & Enteric Diseases, Calcutta.

Data accumulated over the past 20 yr (1969-88) on the phage typing of V. cholerae 01 biotype ElT or strains received at the Vibrio Phage Reference Laboratory, were retrospectively analysed to ascertain the frequency of occurrence of the different phage types of Basu and Mukerjee typing scheme. The analysis revealed that phage types 2 and 4 were the most common types not only at the time when the Basu and Mukerjee typing scheme (of 1968) was introduced but also at present. The existing phage typing scheme needs to be improved with the addition of more new phages to obtain more type distinction and better discrimination within biotype ElT or strains for epidemiological studies.

UI	MeSH Term	Description	Entries
D001434	Bacteriophage Typing	A technique of bacterial typing which differentiates between bacteria or strains of bacteria by their susceptibility to one or more bacteriophages.	Phage Typing,Typing, Bacteriophage,Typing, Phage
D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
