Whole shaken cultures of 20 random, unidentified actinomycetes were extracted with n-butanol at pH 4.5, 7.0, and 8.5, respectively. Residues of butanol-extractable materials (BXM) were reconstituted (100×) in buffers and freeze-dried. BXM were surpr

Summary A series of thiosemicarbazones were studied for antivaccinial activity in chick embryos and in mice. Of those studied, benzaldehyde, 3-thiosemicarbazone, its p-acetamido, p-amino, p-methoxy, p-propoxy and p-ethylsulfonyl analogs were the most

SummaryStreptomycin B, an antibiotic closely related to streptomycin, and seprated from the latter by chromatography, has been studied in vitro against 8 strains or species of bacteria and in each case shown to be less active, on a weight basis, than

SummaryStreptomycin was bactericidal for both multiplying and non—multiplying cultures of K. pneumoniae, but not for washed spores of Bacillus sp. No. 290. Organisms surviving the bactericidal effect of 0.25 unit of streptomycin per ml after 6 hour
