yersinia pseudotuberculosis septicemia. | yersinia pseudotuberculosis septicemia and postdiarrheal hemolytic-uremia syndrome (hus) developed in a 15-month-old boy after he ingested unpasteurized goat's milk. the epidemiology of this organism and the disease states caused by it are discussed with the suggestion that an association between it and some cases of the hus might be found if sought. | 1979 | 571675 |
endemic human plague in new mexico: risk factors associated with infection. | a retrospective case-control study was conducted to identify risk factors, other than contact with infected animal tissues, for infection caused by yersinia pestis in non-indian residents of areas with endemic sylvatic plague in new mexico. the study group consisted of 16 persons who had bacteriologically confirmed cases of plague in the period 1975-1976 and 45 controls who were matched by age, sex, and location of residence. participants were questioned about outdoor activities, environmental c ... | 1979 | 574152 |
yersinia enterocolitica in oneida county, new york. | in a 7-month study during and after an outbreak of yersiniosis in oneida, n.y., a total of 963 specimens were examined for yersinia enterocolitica. of the 103 y. enterocolitica isolates recovered, 91 were from oneida county. sixty-two (60.2%) were from humans including 52 from oneida county. the isolates from the outbreak were mainly serotype 0:8, which on biotypnig proved to be niléhn type 2, wauters type 1, knapp and thal type 2. the rest of the isolates were distributed among various biotypes ... | 1979 | 575321 |
isolation and characteristics of yersinia enterocolitica-like bacteria from meats. | seventeen yersinia enterocolitica-like isolates from vacuum-packaged beef and lamb are described. a majority of the isolates were motile at 25 degrees c but not at 36 degrees c, utilized citrate at 25 degrees c (delayed or negative at 36 degrees c) and produced acid from rhamnose, raffinose and melibiose. increases in count of y. enterocolitica occurred on raw beef stored at 0--1 degrees c over a 10-day period. no viable y. enterocolitica were detected in beef roasts which were inoculated with a ... | 1979 | 575322 |
role of the fly in the transport of yersinia enterocolitica. | yersinia enterocolitica were isolated from flies collected from a piggery and a kitchen of farm and from ham hung in a piggery. the cultures were identified as y. enterocolitica biovar 4 and serovar 3 by biochemical and serological characteristics. from these results it is suggested that flies may play an important role in food contamination by y. enterocolitica. in this study, the probable donors of y. enterocolitica to the flies were swine. | 1979 | 575609 |

epidemic yersinia enterocolitica infection due to contaminated chocolate milk. | in september and october, 1976, an outbreak of illness due to chocolate milk contaminated with yersinia enterocolitica resulted in hospitalization of 36 children, 16 of whom had appendectomies. infection with y. enterocolitica serotype 0:8 was demonstrated in 38 ill persons. sixty-one per cent of the persons who were infected had a titer greater than 1:160 oh agglutinins to serotype 8 yersinia, whereas 48 per cent of the hospitalized children had a fourfold change in agglutinin titer. an epidemi ... | 1978 | 579433 |
isolation of yersinia enterocolitica from raw milk. | four enrichment procedures were used for examining 131 raw milk samples for the presence of yersinia enterocolitica. forty-two isolations were obtained from 19 pooled- (31.1 percent positive) and 10 individual-producer samples (14.3 percent positive). enrichment by butterfields phosphate buffer incubated at 4 degrees c for 14 days and then inoculation of modified rappaport broth incubated at 23 degrees c for 5 days produced the greatest number of isolations. the majority of isolates were biotype ... | 1978 | 579721 |
enterobacteria of emerging pathogenic significance from clinical cases in man and animals and detection of toads and wall lizards as their reservoirs. | a total of 416 samples comprising faecal samples from diarrhoeic cases of man, calves, sheep and goats, and urine samples from patients with urinary tract infections, were examined for the presence of enterobacteria of emerging pathogenic significance. citrobacter freundii from 20, c. intermedius biotype-a from four, serratia marcescens (serotype 05:h13, bactericin type 16) from one and erwinia herbicola from two human stool samples were isolated. only two urine samples yielded c. freundii. citr ... | 1978 | 582096 |

studies on the pathogenicity of yersinia enterocolitica. iii. comparative studies between y. enterocolitica and y. pseudotuberculosis. | comparative studies on pathogenicity between yersinia enterocolitica and yersinia pseudotuberculosis were performed using experimental infection systems in vivo and in vitro. all of thestra ins of both species successfully produced experimental enterocolitis in rabbits although the severity varied with the strains challenged. the changes were characterized by granulomatous lesions with necrobiotic centers in reticuloendothelial tissues of the intestine, mesenteric lymph nodes, liver and spleen. ... | 1977 | 593171 |
[effect of the digestive process on the survival of the plague agent in xenopsylla gerbilli minax fleas]. | hystological investigations of experimentally infected x. gerbilli minax have shown that at the early stages of the digestion, while in the intestine compact clots of non-digested blood, are preserved, proceeds the reproduction of the plague agent. with the decay of the alimentary clot it changes into the dying off of the microbe population and after the ceasing of digestion the accumulation of bacteria renews again. simultaneously with the changes in the number of microbes their morphology vari ... | 1977 | 593719 |
