mitomycin c stimulates production of a toxin in shigella species that causes morphological changes in chinese hamster ovary cells.	shigella dysenteriae produced a toxin that caused morphological changes in chinese hamster ovary cells which was different from the neurotoxin (y. takeda, k. okamoto, and t. miwatani, infect. immun. 18:546--548, 1977). it was found that the toxin was produced not only by s. dysenteriae but also by s. flexneri, s. boydii, and s. sonnei. the production of the toxin was stimulated by the addition of 1 microgram of mitomycin c per ml to the culture in the early logarithmic growth phase.	1979	370009

phagocyte functions in familial mediterranean fever.	monocytes derived from peripheral blood of patients with familial mediterranean fever (f.m.f.) demonstrated lower phagocytic capacity for shigella flexneri and depressed bactericidal activity against s. albus when compared to monocytes from healthy individuals. treatment of patients with colchicine did not alter these functions. on the other hand, chemokinesis of pmn of f.m.f. patients was enhanced especially during attacks. colchicine treatment decreased significantly the pmn chemotactic migrat ...	1979	397753
comparison of some shigella flexneri (escherichia coli) hybrids in cross agglutination and agglutinin absorption tests.	antigenic structure of lac+ hybrids selected from escherichia coli x shigella flexneri crosses was compared in the cross agglutination and absorption tests. identity of the hybrids from the recipients of serotype 2a and variant y was proved, as well as from serotypes 1b and 4b. the latter hybrids were coupled with shigella flexneri strains 3a, 3b and 3c. the hybrids appeared almost identical with serotype 3c.	1979	398206
histoautoradiographic investigation of the invasive dissemination of ehrlich ascites tumor cells through the organs of the mouse.	in this paper the attempt has been pursued to quantify by a well planned experimental technique the ability of the neoplastic cells to spread around in vivo through various organs of laboratory animals. by making use of the histoautoradiographic techniques the incorporation of 3h thymidine either by the normal and by the neoplastic cells has been investigated at many different anatomical sites in ehrlich ascites tumor-bearing mice. the method has been shown to be well suited also for the quantit ...	1979	398216
the intestinal flora and infant botulism.	the intestinal flora of experimental animals interferes with infection by species of salmonella and shigella. protection against infection with these organisms appears to be related to high concentrations of volatile acids, low ph, and low oxidation-reduction potential of the intestinal contents of animals with an intact flora. there are no data to show that the flora influences colonization of the intestine with clostridial species, but indirect evidence suggests that the intestinal flora may b ...	1979	399374
colonization by salmonella typhimurium and shigella flexneri iii of the gastrointestinal tract of mice treated with beta-2-thienylalanine and streptomycin.	mice fed beta-2-thienylalanine (beta-2-t) by oesophageal tube were no more susceptible to gastrointestinal tract colonization by salmonella typhimurium or shigella flexneri iii than control mice fed water. in both beta-2-t-fed and water-fed groups, the increasing dosage of s. typhimurium, in logarithmic increments to groups of mice, resulted in increasing numbers of these bacteria detectable on dilution plates from organ homogenates. colonization by s. flexneri iii only occurred at a dosage of 1 ...	1979	399720
