The conjugative streptococcal transposon Tn916 was found to transfer naturally between a variety of gram-positive and gram-negative eubacteria. Enterococcus faecalis hosting the transposon could serve as a donor for Alcaligenes eutrophus, Citrobacter freundii, and Escherichia coli at frequencies of 10(-6) to 10(-8). No transfer was observed with several phototrophic species. Mating of an E. col...

Blood agar medium was the most suitable medium for isolation of bacteria from household species. On the other hand, several types of media such as blood agar, Littman oxgall agar, brain heart infusion in addition to nutrient agar were good media for isolation ...
