evidence for the retention of kinetoplast dna in an acriflavine-induced dyskinetoplastic strain of trypanosoma brucei which replicates the altered central element of the kinetoplast.a pleomorphic dyskinetoplastic strain of trypanosoma brucei was produced by repeated acriflavine treatment. no kinetoplastic cells reappeared after 2 yr of maintenance in the absence of acriflavine. these dyskinetoplastic cells retained and therefore replicated the central element of the kinetoplast. this element was present in the "condensed" state typical of acriflavine-treated cells rather than the normal fibrillar state. whole-cell dna extracted from both normal and dyskinetoplastic strains ...19714102002

septic gonococcal dermatitis.the overall incidence in gonorrhoea of septic gonococcal dermatitis was found to be 1.9% (3% for the females and 0.7% for the males). in 23 patients the common presenting symptoms were arthritis or arthralgia and bouts of fever, but the characteristic skin lesions served as an early clue to the diagnosis, and neisseria gonorrhoeae was isolated from the genitourinary tract or from the blood. with the use of immunofluorescent techniques gonococci were also found in smears prepared from the skin le ...19715101355

mechanisms and genetics of resistance to sodium lauryl sulfate in strains of shigella and escherichia coli.the sensitivity to sodium lauryl sulfate (sls) of shigella flexneri and escherichia coli is determined by at least three genes. one site is located near the lactose operon, and two loci are cotransducible with the arabinose operon. calcium ions protect against sls lysis. one gene is concerned with the relative ability of the bacterium to retain calcium against such chelating agents as ethylenediaminetetraacetic acid or phosphate buffer. this was first observed in a mutation from virulence to avi ...19715005297

failure of rivalry at low contrast: evidence of a suprathreshold binocular summation process.presentation of different images to the two eyes normally results in a time-varying alternation between the two images (binocular rivalry). however, we find that when orthogonal gratings are viewed dichoptically at low contrast, a stable summation between the two images is perceived in the form of a dichoptic plaid. the range of perception of the dichoptic plaid depends on spatial frequency, contrast and luminance of the gratings. this phenomenon differs from the "false fusion", a fleeting summa ...19711455720
a chromosomal locus which controls the ability of shigella flexneri to evoke keratoconjunctivitis.the primary step in the pathogenesis of bacillary dysentery is the penetration of intestinal epithelial cells by shigellae. lacking this capacity, shigella flexneri becomes avirulent. by means of intergeneric conjugation between various escherichia coli k-12 hfr strains and s. flexneri 2a virulent recipients and by reciprocal transduction analysis with phage p1 vir, we established a locus on the genome of s. flexneri 2a which is necessary for the ability of this strain to penetrate epithelial ce ...197116557949
identification of two widely separated loci conferring nicotinic acid dependence on wild-type shigella flexneri 2a.two widely separated loci causing the nicotinic acid dependence of wild-type shigella flexneri 2a were identified by intergeneric mating procedures and found to be closely linked to the gal and fuc chromosomal determinants.197116558004
antibody response to bacterial antigens: characteristics of antibody response to somatic antigens of salmonella typhimurium.the character of the antibody response in the rabbit to salmonella typhimurium somatic (o) antigen was similar to the response to each of several serotypes of shigella flexneri o antigens, namely a predominance of production of immunoglobulin m (igm) antibody. lipopolysaccharide protein (lpsp) and lipopolysaccharide (lps) fractions of salmonella o antigen differed significantly in both quantitative and qualitative aspects of their immunogenicity. lpsp elicited high levels of agglutinins and also ...197016557720
genetic transfer of shigella flexneri antigens to escherichia coli k-12.the genes controlling synthesis of shigella flexneri group- and type-specific antigens were transferred to escherichia coli k-12 recipients by conjugation with an s. flexneri hfr. after mating e. coli with an hfr strain of s. flexneri 2a and selecting for his(+) recombinants, a high proportion of the e. coli hybrids agglutinated in s. flexneri grouping serum. none of these hybrids expressed s. flexneri type-specific antigen ii. when an e. coli his(+) hybrid possessing the s. flexneri group antig ...197016557729
infection of cultured mouse macrophages with shigella flexneri.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 killed. the attenuated hybrid strain is intermediate in its lethality. comparable results were obtained by using virulent and avirulent s. flexneri 1b, 3, and 5. destruction of macrophages occurs shortly after infection, suggesting virulent strains ...197016557758
inhibition of shigella flexneri by the normal intestinal flora iii. interactions with bacteroides fragilis strains in vitro.five strains of bacteroides fragilis isolated from human feces were assayed for their inhibitory activities against shigella flexneri in vitro. inhibition was not detected when shigella and the bacteroides strains were simultaneously inoculated into a defined liquid medium containing glucose. inhibition was apparent only when shigella was inoculated into established bacteroides cultures. in exponential-phase cultures, the shigella growth rate was diminished and logarithmic growth was prematurely ...197016557847
carrier discretionary practices and physician payment under medicare part b: a preliminary report.although medicare is a national program, administration of part b payments to physicians is in the hands of insurance organizations in ten medicare regions. the carriers follow varying practices in using actual charges within localities as the basis for determining reasonable charges for physicians' services. while some of these practices have already been shown to influence fee levels, reasonable charge determination involves many more whose influence has not been systematically studied. this p ...1970376967

persistence of an escherichia coli-shigella flexneri hybrid in the intestinal tract of macaca mulatta.a live oral vaccine prepared from an escherichia coli-shigella flexneri 4b hybrid was administered by gavage to macaca mulatta. in the three main studies involving 160 monkeys, three doses were used, generally consisting of 5 x 10(9) to 60 x 10(9) cells per dose, with an interval between doses of 6, 7, or 14 days. rectal swab cultures at the time of the last vaccine dose, and 14 to 58 days later, revealed that the hybrid persisted in the intestinal tract for at least 7 days in 16%, and for at le ...19704987199

studies on vaccination against bacillary dysentery. 5. studies in erythrocebus patas.in earlier studies in man it has been demonstrated that streptomycin-dependent shigellae, if given orally in 5 sufficiently large doses, confer a very high type-specific protection against bacillary dysentery.in the present study, 2 groups of erythrocebus patas monkeys were immunized with live streptomycin-dependent shigella flexneri 2a, and a third group was not vaccinated. one of the vaccinated groups was given streptomycin with each dose of the live vaccine. the animals that received streptom ...19704993182

chemotherapy of mice experimentally infected with shigella flexneri.a chronic infection with shigella flexneri 2a has been established in mice for the evaluation of compounds for therapeutic potential. evidence of infection is indicated by prolonged symptomless excretion in the feces and by positive isolation of organisms from different segments of the intestinal tract and from mesenteric lymph nodes. serum antibody titer reaches a maximum after 9 days of infection and remains at a low level until 32 days postinfection. in this model, five drugs used in human sh ...19705422307
