Isolation of Salmonellae and Shigellae from an artificial mixture of fecal bacteria.
Numerous selective media, available commercially, act by suppressing "normal" bacterial inhabitants of the intestine while permitting the growth of so-called pathogenic representatives of the family Enterobacteriaceae. This investigation attempts to evaluate the action of Salmonella-Shigella (SS) agar, xylose lysine desoxycholate (XLD) agar, and hektoen enteric (HE) agar. Salmonellae and shigel...
متن کاملExamination of Feces from Food Handlers for Salmonellae, Shigellae, Enteropathogenic Escherichia coli, and Clostridium perfringens.
Duplicate fecal specimens from food handlers were collected in Louisiana. One set of specimens was examined immediately for salmonellae and shigellae by the Central Laboratory of the Louisiana State Board of Health in New Orleans; the other set was shipped to the Food Microbiology Unit at the Robert A. Taft Sanitary Engineering Center in Cincinnati, Ohio, where it was examined for enteropathoge...
متن کاملBacteriophage lytic patterns for identification of salmonellae, shigellae, Escherichia coli, Citrobacter freundii, and Enterobacter cloacae.
A series of bacteriophages specific for Escherichia coli (E-1, E-2, E-3, and E-4), Citrobacter freundii (phi I, phi II, and phi III), Enterobacter cloacae (Ent), and Shigella spp. (Sh) have been isolated from hospital sewage. These bacteriophages, in combination with Felix Salmonella phage O-I, were used as a diagnostic phage typing set which included seven phage preparations: O-I, C (phi I and...
متن کاملIsolation of Shigellae
The efficiencies of three enrichment broths and four plating media for isolation of enteric pathogens were compared from 1,117 stool specimens. Direct streaking proved to be inferior to enrichment, detecting only 50% of the salmonellae and 61% of the shigellae. By contrast, Selenite Broth (SF) found 90% of the total salmonellae isolates and 82% of the shigellae isolates. Gram-Negative Broth (GN...
متن کاملPurine requiring strains of Shigellae.
The importance of growth factors in the nutrition of shigellae was recognized by Koser and Saunders (1935) and it was shown that the growth factors present in tissue extract could be replaced by nicotinic acid (Koser et al., 1938). The importance of nicotinic acid and nicotinamide as growth factors in the nutrition of shigellae has been shown by Dorfman et al. (1939). Reports of other vitamins ...
