Nitrogen Metabolism of Certain Coliform Bacteria

The Relationship of Shigella Dispar to Certain Coliform Bacteria.

This report deals with serological and biochemical relationships between members of the genus Escherichia and Escherichia-like paracolon bacteria and the microorganisms that are usually classified as Shigella di8par. These studies are part of an investigation on the interrelationships within the family Enterobacteriaceae that was started in 1942 and which is still in progress. Shigella ceylonen...

Slime-producing Coliform and Coliform-like Bacteria.

The nitrogen metabolism of certain strains of Mycobacterium tuberculosis.

There have been numerous studies on the nitrogen metabolism of mycobacteria growing in various culture media, but no work has been reported on the nitrogen assimilation in suspensions of nongrowing cells. For this purpose a number of BCG strains of Mycobacterium tuberculosis were studied for their ability to take up nitrogen in the form of the ammonium ion when shaken aerobically in buffer to w...

Coliform Bacteria in the Intestine of Mice

Mice of the NCS and NCS-D colonies, bred at the Rockefeller University, harbored in their intestine an endemic strain of slow lactose-fermenting Escherichia coli 081+/-: :H21 serotype. In addition, NCS mice have recently acquired E. coli 0109+/-:K48:H14. Both strains persisted during the period of observation, whereas they were not encountered in the feces of mice from two other colonies. Other...
