[mutants of the plaque microbe defective in the dark repair system].	the mutants of plague bacteria deficient in dark repair are described. they are sensitive to uv, mitomycin c, polymixin. mutants have lost the ability to host cell reactivation in phage t7. the data obtained have shown that the addition of caffeine to the plating medium used to assay post-irradiation viability of uv-sensitive mutants did not influence the survival. data are also given concerning virulence determinants, biochemical and other properties. the mutants formed p- colonies on hemine me ...	1977	892436
[classification of acute bacterial enteropathies].	the first part considers pathogenic microorganisms (vibrio cholerae and parahaemolytic vibrio, clostridium welchii, enteropathogenic e. coli, shigella, salmonella, other enterobacteria and pseudomonas. yersinia, simply enterotoxic staphylococcus and that producing acute enteritis) and the process of infection (formation of a surface link without endocellular penetration with elaboration of hexotoxins, formation of a surface link with subsequent intracellular penetration, submucosa penetration). ...	1977	896078
[flea ceratophyllus fasciatus as the vector of the altai-mountain strain of plague microbe].	the work was conducted with a typical strain of the plague agent, which is virulent to white mice and little virulent to guinea pigs (subcutaneous infection), and with c. fasciatus. the fleas of this species can be infected, form the block of proventriculus within 4 to 35 days, transmit the agent during bloodsucking to healthy animals and cause the death both white mice and guinea pigs.	1977	896271

nodular pulmonary infiltrates and septic arthritis associated with yersinia enterocolitica bacteremia.	a 58-year-old black man presented with left wrist pain, septicemia, and a chest roentgenographic pattern compatible with septic embolization. yersinia enterocolitica was grown from joint fluid, blood, and sputum. this unusual constellation of clinical manifestations due to an organism rarely reported as the cause of human disease warrants reporting the case.	1977	900637
yersinia-related arthritis in the pacific northwest.	serologic evidence of yersinia enterocolitica infection was sought by agglutination testing in serum samples from several populations, including haida indians, red cross blood donors, and caucasian patients with rheumatoid arthritis, ankylosing spondylitis, and reiter's syndrome. no evidence was found to indicate that yersinial infection was etiologically related to haida spondylitis or reiter's syndrome. four of 28 patients with acute arthritis were diagnosed from serologic evidence as having y ...	1977	901597
fulminant septicemia caused by yersinia enterocolitica.	a lethal case of septicemia caused by yershia enterocolitica serotype 3 is described. a 59-year-old male, previously healthy, presented with 6 weeks of fever, abdominal pains and gradual prostration ending in overhelming septicemia and death before a conclusive diagnosis was established. necropsy showed cirrhosis, haemochromatosis and numerous abscesses in the liver.	1977	905787
evaluation of live attenuated plague vaccines in praomys (mastomys) natalensis.	a live attenuated yersinia pestis vaccine designated ev76-51f, which had previously been shown to be pathogenic in vervet monkeys but not in guinea pigs, was tested in the multimammate mouse praomys (mastomys) natalensis. doses of 10(6) viable organisms inoculated subcutaneously as either a lyophilized suspension or an agar-grown culture resulted in vaccination fatalities in praomys but not in white mice. hemagglutinating antibodies to the fraction 1 antigen were not stimulated by doses lower th ...	1977	908624
epidemiologic and clinical features of an outbreak of bubonic plague in new mexico.	an outbreak of seven cases of bubonic plague in new mexico was investigated. clinical features were studied and correlated with field studies in an attmept to determine the source of infection in patients with indefinite histories of exposure. most patients presented with fever, malaise, and an acute painful lymphadenitis (bubo). one death occurred in a patient with bubonic-septicemic plague complicated by meningitis due to yersinia pestis. all patients lived in rural or semirural areas, and mos ...	1977	908848
studies on the pathogenicity of yersinia enterocolitica. i. experimental infection in rabbits.	analysis of the pathogenicity of yersinia enterocolitica was performed with an experimental model successfully produced in rabbits by intraduodenal inoculation with strains isolated from various sources. pathogenic strains easily penetrated the epithelial linings of the intestinal mucous membrane into the target reticuloendothelial tissues of the intestine, such as the lamina propria and lymph follicles, where they multiplied within mononuclear cells and produced granuloma. granuloma, in severe ...	1977	909458

antibodies to yersinia enterocolitica in thyroid disease.	the prevalence of elevated antibody titers against yersinia enterocolitica was studied in normal subjects, patients with a variety of nonthyroidal illnesses, and patients with thyroid disease. in contrast to the low prevalence of antibodies in controls (less than 8%), 48 of 67 patients (75%) with a variety of thyroid disorders had titers greater than 1:8. antibodies were found in 24 of 36 patients with graves' disease, five of six with autonomous adenoma, seven of seven with hashimoto's thyroidi ...	1976	1036668
distribution of beta-lactamases a and b in some groups of yersinia enterocolitica and their role in resistance.	yersinia enterocolitica w222 (serological group 3) synthesized two different intracellular beta-lactamases, called a and b. enzyme b was more sensitive than a to inhibition by cloxacillin. the minimum inhibitory concentrations of various beta-lactam antibiotics for strains of y. enterocolitica of groups 3 and 9 and the effect of cloxacillin on these concentrations suggested differential roles for beta-lactamases of types a and b in penicillin and cephalosporin resistance. type b enzymes protecte ...	1975	1043914

[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

[bacteriocinogeny in yersinia enterocolitica].	bacteriocinogeny was found in 19.8 per cent of y. enterocolitica strains tested. it was designated by the authors as enterocoliticacinogeny and the substance produced by the pathogen was named enterocoliticacine. bacteriocinogeny was found among the collection strains isolated in the south primorye and not among the strains isolated abroad. some cultures of y. enterocolitica isolated abroad and in the south primorye were used as indicator strains for revealing enterocoliticacinogeny. enterocolit ...	1975	1091204

[a comparative immunochemical study of the subtypes of serologic type i of the agent of pseudotuberculosis].	it was shown that y. pseudotuberculosis strains causing the far-eastern scarlatina-like fever in the primorsk region belonged to subtype ib-ipopolysaccharides of the standard strain of subtype ib and of the local strain were closely affiliated by the analytic data and monosaccharide composition, but differed from the lipopolysaccharide of strains belonging to subtype ia. living vaccines should be used to obtain the sera against the subtypes ia and ib of the causative agent.	1975	1092107
