Infant and weanling mice infected experimentally with non-neuroadapted Western equine encephalitis virus exhibited a differing spectrum of target-organ pathology as well as a different clinical response. The infant mice sickened and died within 48 hr

This report deals with the incorporation of cystine into macromolecules by yeast cells of Histoplasma capsulatum . The results show that at saturating concentrations of cystine in a rich medium, total uptake of the cystine occurs in 10 hr, whereas th

We compared the polynucleotide sequence relationships of three strains of Chlamydia trachomatis of human origin (MRC-1/G, TW-3, and Lgv), one of murine origin (MoPn), and the MN strain of C. psittaci. The four strains of C. trachomatis have the same

Susceptibility to enteric infection with Salmonella was studied in mice housed at different temperatures. The oral doses of S. typhimurium SR-11 and RIA, which caused 50% mortality in animals at 10 C, were about 1/30 and 1/100 of the respective value

Five mutagens were used to induce mutants of Candida albicans. Ultraviolet light, N -nitroso- N ′-methyl- N -nitrosoguanidine, and N -nitroso- N -methylurethane were effective mutagens which induced stable auxotrophs. N -nitroso- N -methylurethane

Hot phenol-water extraction of smooth Brucella abortus and B. melitensis cells yielded a toxic fraction which was recovered from the phenol phase (fraction 5). Chemically, fractions 5 from both Brucella species were lipid-carbohydrate-protein-2 keto-

After prolonged treatment with methicillin and penicillin, L-forms were prepared from 12 of 22 strains of Staphylococcus aureus . These L-forms were obtained from five of nine strains which produced enterotoxin A, from three of six strains that produ

The effect of several steroid hormones on the susceptibility of mice to infection with MM virus was studied. Estrone, cortisone, and hydrocortisone increased mortality, whereas progesterone, prednisolone, and testosterone had no effect. The viral inf

A spontaneously occurring stable deuterium-tolerant mutant was selected from highly virulent Pasteurella tularensis strain SCHU S4; the frequency of mutants in the cell populations was between 10 −3 and 10 −4 . Upon cultivation of parent strain S

Virulent, avirulent, and attenuated hybrid strains of Shigella flexneri 2a are equally susceptible to phagocytosis by cultured mouse peritoneal macrophages. The virulent strain is highly lethal for the macrophages, whereas the avirulent is not and is
