paratyphoid fever/carbohydrate

In a stock culture of the hog-cholera bacillus, which was passed through a series of rabbits 14 years ago, an organism was found that differs from the original culture in that it fails to form gas from the carbohydrates that are usually attacked by this organism, while acid formation persists. This

The 24 most frequently isolated paratyphoids from poultry, along with Salmonella gallinarum and Salmonella pullorum, plus strains of Arizona, Citrobacter, Edwardsiella, Escherichia, Klebsiella, Prteus, Pseudomonas, Serratia and Shigella were inoculated into triple sugar iron (TSI) and lysine iron

Salmonella enterica serovar Choleraesuis strain C500 is a live, attenuated vaccine that has been used in China for over 40 years to prevent piglet paratyphoid. The objective of this study was to evaluate the potential of attenuated Salmonella enterica serovar Choleraesuis C500 strain with a delta

The inhibition produced by the lytic agent on the growth of Bacillus coli is greatly influenced by the reaction of the medium; it is faint in a slightly acid (pH 6.8) or neutral (pH 7) or even slightly alkaline broth (pH 7.4), but is much stronger in a more alkaline medium (pH 8 or 8.5). We have

Specific precipitable substances rich in carbohydrates, containing very little protein and small amounts of a material apparently of fatty nature, have been prepared from the main serological types of the typhoid-paratyphoid groups. The preparations in their present state of purity do not exhibit
