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...

26 Background: Shigellae have become increasingly resistant to the extended-spectrum 27

Results of tests made in 1964 confirm the previous findings that live oral vaccine, prepared from streptomycin-dependent strains of shigellae, confers a strong, type-specific protection against acute bacillary dysentery. This vaccine did not reduce the carrier rate of shigellae. Observations on soldiers treated with a vaccine of Shigella flexneri serotypes 2a and 3 combined revealed no antagoni...

The methanolic extract of leaves of Mesua ferrea Linn. were tested for its antibacterial potentiality against 103 various strains of bacteria including Staphylococcus aureus, Bacillus spps. Klebsiella spps., Streptococus pneumoniae, Sarcina lutea, Lactobacilus arabinosus, Escherichia coli, shigellae, salmonellae, Proteus spps., Pseudomonas spps. and the vibrios. Significant antibacterial effect...

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 ...
