lytic replication of coliphage lambda in salmonella typhosa hybrids.hybrids between escherichia coli k-12 and salmonella typhosa which conserved a continuous k-12 chromosomal diploid segment extending from pro through ara to the stra locus were sensitive to plaque formation by wild-type lambda. these partially diploid s. typhosa hybrids could be lysogenized with lambda and subsequently induced to produce infectious phage particles. when the k-12 genes were segregated from a lysogenic s. typhosa hybrid, phage-productive ability was no longer detectable due to los ...19724555401
water-borne typhoid fever caused by an unusual vi-phage type in edinburgh.investigation of a small series of cases of typhoid fever infected in a river between 1963 and 1970 revealed that all were caused by a single source, a carrier of a rare phage type of salmonella typhi. the contamination of the river resulted from an incorrect sewage connexion with a surface water drain outfall into the river.19724555889

chloramphenicol resistance in the typhoid bacillus.chloramphenicol resistance has been reported in individual strains of salmonella typhi since 1950, but there had been no accounts of epidemics caused by resistant strains of the organism until 1972, when one occurred in mexico. two british patients have been infected in that country, and the organism isolated from them corresponds in all respects with the description of the mexican epidemic strain of s. typhi: it is a degraded vi strain resistant to chloramphenicol, streptomycin, sulphonamides, ...19724558307

molecular studies of r factor compatibility groups.molecular studies of r factors of six groups, f(ii), i(1), i(2), n, b, and h, defined on the basis of compatibility, support the conclusions drawn from genetic studies. in general, r factors of a given compatibility group are similar in size. deoxyribonucleic acid (dna) reassociation occurs freely between members of the same group but is minimal between heterologous groups. an exception to this was found in group h, of which one factor showed minimal homology with the remaining plasmids of the g ...19734577745

mutants of group d1 salmonella carrying the somatic antigen of group a organisms: isolation and serological characterization.o antigen mutants were obtained from salmonella durban, a group d(1) organism, by treatment with n-methyl-n'-nitro-n-nitrosoguanidine. serological studies demonstrated that the mutants lost the o-9 antigen factor of the parent organism but acquired the o-2 factor specific to group a salmonella. lipopolysaccharides of the mutant strains contained paratose which determines the specificity of o-2 factor. tyvelose, present in the wild-type lipopolysaccharide, was not found in the mutants. h antigens ...19744587616

maturation of the humoral immune response in mice.in spite of the prenatal appearance of immunoglobulin-bearing lymphocytes and theta-positive lymphocytes in the spleens of swiss-l mice, these mice are not able to produce detectable levels of humoral antibodies in response to antigen until after 1 wk of age. adult levels of response are not achieved until 4-8 wk of age. in the presence of bacterial lipopolysaccharides, which can substitute for or enhance t-cell function, the b cells from young swiss-l mice were found to be indistinguishable in ...19744589987
functional characteristics of peyer's patch lymphoid cells. ii. lipopolysaccharide is thymus dependent.this study shows that lps is not mitogenic in cultures containing b cells, or b cells and accessory adherent cells or me, unless t cells are present. this observation rules out models of induction of antibody synthesis in which it is assumed that the delivery of a mitogenic signal by the interaction of lps with the membrane of the b cell is in itself sufficient for b-cell induction (19). further, it makes unlikely the proposed extrapolation of such a model to other so-called thymus-independent a ...19744589992

drug resistance of coliform bacteria in hospital and city sewage.the number and properties of drug-resistant coliform bacteria in hospital and city sewage were compared. there was little difference in the counts of organisms with nontransferable resistance to one or more of 13 commonly used drugs. an average of 26% of coliforms in hospital waste water had transferable resistance to at least one of the drugs ampicillin, chloramphenicol, streptomycin, sulfonamide, or tetracycline as compared to an average of 4% in city sewage. r(+) bacteria in the hospital disc ...19734597713

comparative survival of indicator bacteria and enteric pathogens in well water.the comparative survival of various fecal indicator bacteria and enteric pathogens was studied in a stable well water supply by using membrane chambers. there was more variation in the 29 coliform cultures and they died more rapidly, as a group, than the 20 enterococcus cultures that were examined. the comparative survival of the organisms tested follows: aeromonas sp. > the shigellae (shigella flexneri, s. sonnei, and s. dysenteriae) > fecal streptococci > coliforms = some salmonellae (salmonel ...19744598219
role of typhoid antigens in protection and pathogenicity for mice.swiss white mice immunized with acetone-killed vaccines prepared from strains of salmonella typhosa, s. typhimurium, and mouse-virulent s. typhimurium hybrids which had acquired, by conjugal genetic transfer, the s. typhosa antigens 9, vi, and d were challenged with the s. typhimurium hybrids and with the s. typhimurium parent strain. the results of these experiments suggested that the salmonella somatic antigens were important in conferring protection against death in this system. the s. typhos ...19744598256

r factors in strains of salmonella typhi and shigella dysenteriae 1 isolated during epidemics in mexico: classification by compatibility.all 17 salmonella typhi strains tested from the epidemic in mexico carried r factors of compatibility group h, conferring resistance to chloramphenicol, streptomycin, tetracycline, and sulfonamides. some s. typhi strains carried, in addition, non-conjugative, ampicillin resistance plasmids and r factors of the i or a-c complex. all 20 shigella dysenteriae 1 strains tested of epidemic origin carried o-group r factors. ampicillin resistance in s. dysenteriae 1 was not proved to be plasmid borne. r ...19744599123

salmonella typhi resistant to chloramphenicol, ampicillin, and other antimicrobial agents: strains isolated during an extensive typhoid fever epidemic in mexico.during 1972 a large epidemic, in excess of 10,000 cases, of typhoid fever occurred in mexico city, pachuca, and other communities of mexico. the main characteristic of the epidemic, in addition to the large number of persons affected, was the prevalence of a strain of salmonella typhi which was highly resistant to chloramphenicol both in vivo and in vitro, and which belonged to a single phage type, vi degraded approaching type a. of 493 strains of s. typhi studied during the outbreak, 452 (91.7% ...19734602828

a one-day selective migration procedure for detecting salmonellae in faeces.a one-day procedure for detecting salmonellae was developed and evaluated with clinical faecal specimens. the procedure was based on the selective retardation of enterobacteria in their migration through a semi-solid enrichment medium. it was shown that a pure or almost pure growth of salmonella could often be obtained within 16 to 24 hours by this method. the culture thus obtained could then be used directly for serological confirmation. the method was rapid, economical, and efficient. clinical ...19744604024
