Bacteriological Studies on Interference Phenomenon with Bacterium Tularence

Bacteriological and Experimental Studies on Gastric Ulcer

It must be assumed that some cause is operative in certain cases preventing the healing of defects in the gastric mucosa and is inoperative in others. Even though anhemolytic streptococci are present in practically all gastric ulcers, we cannot convince ourselves that these organisms have been proven as yet to be the factor which either initiates the ulceration or prevents healing. Nevertheless...

Clinical and bacteriological studies with clindamycin.

Fifty patients have been treated with clindamycin, a chemical analogue of lincomycin. Forty-four responded satisfactorily to treatment. Gastrointestinal side-effects were rare though five patients developed rashes. Most recently isolated staphylococci are clindamycin-sensitive.

Studies on the Shwartzman Phenomenon

Formalin induces a considerable change in meningococcus culture filtrates. This consists of a marked decrease in toxidty as concerns both the Shwartzman phenomenon and the lethal effect, with relative preservation of the antibody-combining capacity and antigenicity. A similar modification occurs spontaneously in meningococcus culture filtrates on standing. Inasmuch as these changes parallel tho...

Bacteriological Studies in Epidemic Dropsy

A bacteriological and serological study of organism B5W (Bacterium antiratum).

Over a period of several years there has been isolated in the laboratories of the Receiving Hospital, Detroit, an unusual gram-negative organism, characterized by mucoid growth and relatively simple biochemical activity, which fits into no known bacteriological classification. A large percentage of these cultures were isolated from urine specimens, although an occasional strain was found in spu...
