| host responses to infection with yersinia enterocolitica. | the mechanism of protective systemic immunity to y. enterocolitica infection in mice was studied. it was determined that active immunization of mice with heat-killed yersiniae would induce a protective immune response against an intravenous challenge. this protective response was proven to be humoral in nature when it was demonstrated that passively transferred serum, but not cells, protected normal recipients against a lethal challenge. it was also shown that the immune serum caused opsonizatio ... | 1979 | 535391 |

| isolates of yersinia enterocolitica from clinical cases in northern israel. | bacteriologic data and some clinical and epidemiologic aspects concerning 53 clinical cases associated with yersinia enterocolitica are described. this is the first published report of human cases of y. enterocolitica infection in israel. seventy-eight isolates of y. enterocolitica were obtained from stool cultures of these cases, with 94% on ss agar plates. the isolation of the organism, including its differentiation from related bacteria, is discussed. in 88% of 50 cases, the organisms were of ... | 1978 | 738869 |
| [survival of yersinia enterocolitica in the environment (author's transl)]. | laboratory experiments have proved that at ambiant temperature in shade y. enterocolitica can survive in surface water as well as in a dried state. survival time is variable: (1) in sea water, some strains disappeared in a few days while other strains survived several weeks (2) in spring water, with little organic matter, the number of living organisms diminished rapidly and none could be cultivated after one and a half months, (3) in dry chemically pure sand, the number of living organisms bega ... | 1978 | 749056 |
| pathogenicity of various yersinia enterocolitica serotypes towards mice of swiss and balb/c strains. | series of experiments aimed at determining ld50 of various y. enterocolitica serotypes toward mice of swiss and balb/c strains infected by different route have been made. it appeared impossible to establish the ld50 in mice of swiss strains after a single and repeated intravenous infection. attention has been paid to a clear relationship between the mortality of balb/c mice and culture conditions of y. enterocolitica strains used for infection. in regard to particular serotypes lc50 could be det ... | 1978 | 749814 |
| humoral and cellular immune reaction in balb/c mice infected with yersinia enterocolitica. | experiments were carried out on balb/c mice infected with y. enterocolitica serotypes ia, ib, ii, iii, iv, v and vi (according to knopp and thal) to check humoral and cellular immune response both primary and secondary. it was shown that the occurrence of anti-oh agglutinins and their dynamics depends on the serological type of y. enterocolitica used for infection, and that it is related to the primary and secondary challenge. the presence of anti-oh agglutinins and hemagglutinins was observed o ... | 1978 | 749815 |
| the usefulness of various yersinia enterocolitica antigens for passive hemagglutination test. | using various antigen preparations of seven yersinia enterocolitica serotypes (according to knapp and thal) and homologous rabbit immune sera the author succeeded in standardization of passive hemagglutination test. the usefulness of preparations termed "supernatant" derived from heated cells at 100 degrees c and lyophilized "crude" preparations of all serotypes were assessed using blood donors' sera and sera of subjects suspected of infection with y. enterocolitica. it has been shown that thoug ... | 1978 | 749816 |
| standardization of the agglutination test in the diagnosis of yersinia enterocolitica infection. | for preparation of antigens standard strains of yersinia enterocolitica representing serological groups i to vi (according to knapp and thal) were used. the following antigens preparations were used: antigens autoclaved at 121 degrees c, antigens treated with formaline and living cells. the antigens were titrated against homologous immune sera, and their optical density was estimated spectrophotometrically. in the rabbit immune sera, and additionally, in the sera of blood donors and subjects sus ... | 1978 | 749817 |
| yersinia enterocolitica as a cause of infantile diarrhoea in rio de janeiro, brazil. | yersinia enterocolitica is reported as the causative agent of infantile diarrhoea in rio de janeiro. four strains were isolated from 70 children with diarrhoea. apparently, this is the first report of y. enterocolitica-associated diarrhoea in latin-america. | 1978 | 751117 |
