[yersinia enterocolitica--a still infrequently isolated pathogen in austria (author's transl)].yersinia enterocolitica--recognized as a distinct taxonomic entity in 1964--belongs to the family of enterobacteriaceae. it has been isolated with increasing frequency from human and animal sources as well as from food and non-chlorinated water. yersinia enterocolitica can produce enteritis in man, accompanied or followed in adults by erythema nodosum, arthralgia and/or acute arthritis. rarely, septicaemia with a high mortality rate has been encountered. a cold-temperature enrichment method was ...1979433284
evaluation of some cold enrichment and isolation media for the recovery of yersinia enterocolitica.an evaluation of several cold enrichment media for yersinia enterocolitica showed that the enrichment quotient achieved after 3 weeks at 4 degrees c was highly dependent on the initial cell concentration and the medium used. the latter should be of high nutritional value, in order to allow sufficient growth of yersinia enterocolitica at a low temperature. enrichment in typtone--soya broth yielded better results than in--frequently used--phosphate buffer, ph 7.6. while comparing isolation media f ...1979400084
yersinia enterocolitica among small wild mammals in france.a survey of yersinia enterocolitica was made in two french areas (indre and alsace) in several components of the terrestrial ecosystem. y. enterocolitica has been isolated from several habitats and from numerous species of small mammals. the trap line method enabled us to estimate the density of the two abundant small mammal species, microtus arvalis and apodemus sylvaticus, and the densities of y. enterocolitica carriers. the frequency of isolation was high when temperatures were low, but did n ...1979400946
differentiation of selected enterobacteriaceae by pyrolysis-gas-liquid chromatography.pyrolysis-gas-liquid chromatography was used to differentiate selected species of enterobacteriaceae. individual cultures of salmonella typhi, hafnia alvei, and proteus vulgaris, and 12 strains of yersinia enterocolitica were grown in nutrient broth. after harvest and lyophilization, the bacterial samples were pyrolyzed at 900 degrees c, and their volatile fractions were separated on a 50-m capillary column coated with carbowax 20m. the resulting pyrolysis elution patterns (pyrograms) of the fou ...1979393169
human gastrointestinal infections by yersinia enterocolitica.in an average-sized peripheral hospital in belgium, y. enterocolitica has been isolated from 1.1% of stool cultures, using an unmodified routine technique. in a group of unselected patients undergoing appendicectomy, 1.3% of patients had a positive culture, either from the mesenteric lymph nodes or the appendix, or from both sources. in the same group of patients, 1.7% of cultures grew a salmonella. in more than half of the patients, the diagnosis of mesenteric adenitis was made during the surgi ...1979394918
the pathogenesis of yersinia enterocolitica gastroenteritis.of nine y. enterocolitica serotypes examined by us, only type 3 was shown to be enteropathogenic. 3 of 16 strains recovered from clinical material, produced a heat-stable toxin similar to that reported in e. coli. a fourth isolate produced histological changes resembling those associated with salmonellae. the mechanism whereby the majority of y. enterocolitica strains produce diarrhoea is uncertain. our isolates may have lost a plasmid essential for enteropathogenicity, or they may resemble the ...1979394919
enrichment methods for recovery of yersinia enterocolitica from foods and raw milk.modified rappaport broth used directly and in a two-step procedure with preliminary cold enrichment was evaluated for recovery of yersinia enterocolitica from laboratory-inoculated samples of ground meat, and naturally-occurring strains from raw milk. the use of modified rappaport broth generally improved recovery from both inoculated meats and raw milk, but results were not consistent between serotypes used for inoculation and between meat samples. the overall isolation rate for naturally-occur ...1979394916
testing for the recovery of yersinia enterocolitica in foods and their ability to invade hela cells.tests have demonstrated that current enrichment methods may fail to detect low levels of some clinical strains of yersinia enterocolitica inoculated into meats and oysters and need improvement. the results of cold enrichment with phosphate and tripolyphosphate buffers were very poor and the sensitive clinical strain failed to grow in wauters' mgcl2 broth. twenty typical clinical strains of y. enterocolitica belonging to nilehn's biotypes 2, 3, and 4 had the ability to invade hela cells tissue cu ...1979394917
[purification and physico-chemical analysis of the fimbrial antigen in two different genera of enterobacteriacea: salmonella enteritidis and yersinia enterocolitica (author's transl)].chemical, physical and immunological properties of the fimbrial antigen of two different genera of enterobacteriaceae, namely salmonella (s. enteritidis) and yersinia (y. enterocolitica) were analysed. only a few strains of these two bacterial genera possess a fimbrial antigen which proved to be identical in all tests. purified fimbriae are unstable in buffer solutions. they tend to form aggregates, patterns of which are between 240000 and 270000. submitted to solubility testing by various metho ...1979377854
measurement of immunoglobulin m (igm), igg, and iga antibodies against yersinia enterocolitica by enzyme-linked immunosorbent assay: persistence of serum antibodies during disease.an enzyme-linked immunosorbent assay for the detection and quantitation of human immunoglobulin m (igm), igg, and iga antibodies against yersinia enterocolitica is described. formalinized or heat-treated bacteria were adsorbed onto specially designed microcuvettes, and antibodies were allowed to attach to the antigen-coated cuvettes. rabbit anti-human mu, anti-human gamma, and anti-human alpha antisera were allowed to react with human antibodies, and these class-specific anti-immunoglobulins wer ...1979379030
yersinia enterocolitica infections in children.y. enterocolitica has been increasingly associated with a wide range of age-related clinical manifestations in children and adults, including febrile gastroenteritis, pseudoappendicitis, arthritis, sepsis, and focal suppurative disease. although definite patterns of incidence, prevalence, transmission, and pathophysiology are emerging, much remains to be explained. the alert clinician who notifies his clinical laboratory colleagues that special isolation techniques are required to recover this o ...1979379783
yersinia enterocolitica enteritis in children.five patients were admitted to children's hospital national medical center with manifestations of yersinia enterocolitica infections. four of five had primarily enteric illness, while the fifth had associated ocular and joint involvements. in three of five cases, the disease was self-limiting. two of the patients (no. 1 and 2) may have had their disease improved by antibiotic therapy. increased alertness to the potential of y enterocolitica to cause a variety of syndromes is necessary to make an ...1979480643
[season-related incidence of yersinia enterocolitica in fecal material of healthy slaughterhouse pigs (author's transl)].in the period july 1976 to june 1977 a total of 1358 fecal specimens and 165 mesenteric lymphnodes of healthy slaughterhouse pigs were examined for yersinia enterocolitica (y.e.). the animals originated from 215 farms in 86 localities of northern bavaria. y.e. was found in fecal specimens of 371 pigs (27.3%). a total of 408 strains was isolated including 35 double and one triple infections. most cultures belonged to serogroups o:6...(186 strains), o:7...(78 strains), and o:5...(71 strains, table ...1979543351

anticomplementary activity in diffuse and nodular goiters.the occurrence of anticomplementary activity and its correlation to serum thyroglobulin was investigated in 71 patients with thyroid diseases and 63 age and sex matched control subjects. the patients which were subgrouped according to thyroid function and characteristics of the goiter, were examined at the time of diagnosis. the anticomplementary activity was measured by a complement consumption (cc) assay. sera from patients with graves' disease and nontoxic diffuse goiter, showed stronger acti ...1979583537
antibiotic-resistance transfer in yersinia enterocolitica.most clinical isolates of yersinia enterocolitica have been reported to be inhibited by a wide variety of antimicrobial agents. this finding indicates that y. enterocolitica infrequently acquires resistance by gene transfer from other bacteria in nature. in the present study the authors examined whether y. enterocolitica has the potential for acquiring antibiotic resistance from another organism in vitro. mixed cultures of multiple-antibiotic-resistant escherichia coli and a sensitive y. enteroc ...1979420178
evaluation of a pectin agar medium for isolation of yersinia enterocolitica within 48 hours.a modified pectin agar medium was evaluated for the rapid isolation and presumptive identification of yersinia enterocolitica. of 118 isolates of enterobacteriaceae tested, only the 13y. enterocolitica and the three klebsiella oxytoca strains produced colonies that depressed and sank into the agar. yersinia enterocolitica was also easily identified in mixed cultures, even from inocula containing three times as many other enterobacteriaceae organisms as y. enterocolitica. the recovery of y. enter ...1979495561

carriage of yersinia enterocolitica serotype 3 by pigs as a source of human infection.bacteriological cultures were made from pigs' tongues bought in several belgian butchers' shops, for 3 years in succession. from 302 samples 168 yersinia enterocolitica strains were isolated, all of serotype 3, except three strains belonging to serotype 9. the isolation rate ranged from 53 to 62.5%, depending on the year. the modified rappaport broth supplemented with carbenicillin proved to be highly superior to the cold enrichment method for recovering the organism from this material. it is as ...1979535380
radiation resistance and injury of yersinia enterocolitica.the d values of yersinia enterocolitica strains ip134, ip107, and wa, irradiated at 25 degrees c in trypticase soy broth, ranged from 9.7 to 11.8 krad. when irradiated in ground beef at 25 and -30 degrees c, the d value of strain ip107 was 19.5 and 38.8 krad, respectively. cells suspended in trypticase soy broth were more sensitive to storage at -20 degrees c than those mixed in ground beef. the percentages of inactivation and of injury (inability to form colonies in the presence of 3.0% nacl) o ...1979570017
occurrence of yersinia enterocolitica in the throat of swine.yersinia enterocolitica serotype 0 3 was isolated from 84 (30%) of 282 throat swab cultures from bacon pigs at slaughter. other serotypes of y.e. were not isolated. all the isolations were made by the cold-enrichment method. the serum agglutinin titres against serotype 0 3 were low in most of the pigs examined. the rate of isolation of the organism increased with rising serum titre. in denmark, y.e. serotype 0 3 would appear to be a common inhabitant of the throat of swine.1979535381
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 ...1979575321
investigations of source and route of yersinia enterocolitica infection.isolation of yersinia enterocolitica was performed on healthy humans, animals and food, and growth of y. enterocolitica on sliced ham at various temperature ranges was also examined. it was noticed that the most prevalent 0 group (03) in human infection was isolated from swine, pork and chopping boards. the storage of food in the refrigerator (5 degrees c) possibly increases the risk of infection since y. enterocolitica is multipliable at low temperatures more readily than many other pathogenic ...1979535369
comments on the ecology and epidemiology of yersinia enterocolitica in czechoslovakia.on the basis of the information disseminated by the reference laboratory in 1968, the microbiological diagnosis of yersinia enterocolitica (ye) was gradually mastered by all czechoslovak microbiological laboratories. the most frequent serotype isolated in man was ye 03. isolation predominated from cases of diarrhoea, less often from appendectomies, and only one case of septicaemia was described. usually only sporadic cases occur and outbreaks are rare. a few strains of ye 05 were found in diarrh ...1979535370
