Vibrio bacteria research studies

The discovery of S. montevideo in the water supply of a collective settlement in Galilee (Israel) prompted the investigators to examine for enteropathogens all those waters that could be considered suspect either because of their appearance (turbidity, particularly after inundations) or because unexplained enteritis cases occurred amongst the users of a given water. A total of 400 water samples were examined for the number of bacteria (colony count) and for the number of fecal Escherichia coli (complete test) according to standard methods. The samples were also tested for enteropathogens by centrifuging twenty milliliters of water at 2,000 rpm for 15 minutes. The deposit was cultured in a Mueller‐Kauffmann enrichment medium from which BGB plates were inoculated and suspicious colonies were identified by the usual biochemic and serologic methods. The isolated strains were submitted for confirming tests to the Israel Salmonella Center in the Central Laboratories at Jerusalem.
