yersinia pestis: correlation of ultrastructures and immunological status.	ultrastructural identification and localization of the fraction 1 "envelope" antigen in the plague bacillus yersinia pestis were the primary objectives of this brief study. the antigenicity of extra-cellular material between the bacilli in undisturbed cultured colonies and that of the pathogen per se were measured and correlated by means of the semi quantitative complement fixation method after incubation for 72 h at 37 c. when the amount of extracellular substance in wild-type t1 (virulent) bac ...	1975	1095487
restriction of dna in yersinia enterocolitica detected by recipient ability for a derepressed r factor from escherichia coli.	a derepressed r factor, ry2drd2, was transferred at a frequency of 5x10minus 3 between two strains of yersinia enterocolitica mated on a membrane. under the same conditions transfer of this r factor from escherichia coli to y. enterocolitica was observed at a frequency of only 7-7x10minus 6. this frequency was greatly increased when the recipient strain was heat-treated before mating. heat exposure for optimum fertility was 50 to 52 degrees c for a period of 2 to 3 min. mutants of y. enterocolit ...	1975	1095683

methionine transport in yersinia pestis.	yersinia pestis tjw, an avirulent wild-type strain, requires phenylalanine and methionine for growth. it was of interest to examine and define the methionine transport system because of this requirement. the methionine system showed saturation kinetics with a km for transport of approximately 9 times 10(-7) m. after 8 s of methionine transport, essentially all of the methionine label appeared in s-adenosyl-l-methionine (sam) as detected in ethanol extracts. small amounts of free methionine was d ...	1975	1176434

[drug sensitivity of yersinia enterocolitica and yersinia pseudotuberculosis].	drug-sensitivity of 70 strains of y. enterocolitica and 24 of y. pseudotuberculosis including reference strains and isolates from men or animals were determined by the agar plate-dilution method. all the strains of y. enterocolitica were relatively resistant to penicillins and cephalosporins, while all of y. pseudotuberculosis were sensitive to both of the agents. most of the strains of both species excluding 13 resistant ones were sensitive to streptomycin. the resistant strains, however, were ...	1976	1047115
yersinia enterocolitica : a review of its role in food hygiene.	since yersinia enterocolitica, now classified as a member of the enterobacteriaceae, was recognized as a distinct species in 1964 it has been isolated with increasing frequency from man and animals (including dogs and pigs) and from some human foods. y. enterocolitica infections are now seen as a cause for some concern in both human and veterinary medicine. the organism is commonly found in specimens from swine slaughterhouses and has been isolated from samples of market meat, vacuum-packed beef ...	1976	1087589

a comparison of serological tests for detecting antibody to plague.	a study was undertaken of the relationship between the passive haemagglutination and haemagglutination inhibition tests used in serum surveys for specific plague antibodies. both techniques gave similar titres for sera of albino rattus norvegicus convalescent from plague infection. they appear to be equally suitable for plague surveillance and control programmes.	1976	1088106
indirect immunofluorescence staining of human thyroid by antibodies occurring in yersinia enterocolitica infections.	in the diagnostic routine for tissue antibodies, using indirect immunofluorescence on cryostat sections of human thyrotoxic thyroid, rat stomach and kidney, ninety-six out of 48,388 sera showed a marginal staining of the membrane region of thyroid epithelial cells but no other reaction. twenty-six of these sera were from patients with acute yersinia enterocolitica serotype 3 infection but without signs of thyroid disease. fifty of sixty-three sera with agglutinins against y. enterocolitica serot ...	1976	780011

[arthropodan vectors of human parasites: their pathology and defence reactions (author's transl)].	many infectious diseases of man are transmitted by arthropods. it is not known whether the carriers were primarily susceptible or insusceptible as the cycle first came into existence. similarly so little is understood, why some arthropods are suitable vectors and other close relatives are not suitable. only the hypothesis that the agents are original parasites and not at all commensals or symbionts can reasonably explain the evolution of the cycles. it is shown by means of numerous examples how ...	1976	769379
