| isolation of yersinia enterocolitica and yersinia pseudotuberculosis from human specimens and their drug-resistance in the niigata district of japan. | a total number of 60 yersina strains (yersinia enterocolitica 58; yersinia pseudotuberculosis 2) were isolated from 58 patients who were more or less doubtful to yersinia infection in the niigata district. an etiologic significance with respect to serogroup and biovar was investigated from the following viewpoints, (1) serum agglutinin titer; (2) positive recovery in the follow-up; (3) relation of positive specimen to the inflammatory lesion, (4) comparison with the isolates from a healthy group ... | 1979 | 535368 |
| 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 ... | 1979 | 535369 |
| 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 ... | 1979 | 535370 |

| canadian experience with yersinia enterocolitica (1966--1977). | data pertaining to 1,219 cultures of yersinia enterocolitica isolated in canada are summarized. of the 977 cultures isolated from humans, y. enterocolitica serotype 0:3, biotype 4, phage type ixb was the most predominant type in ontario, quebec and the four eastern provinces. in the western provinces the predominant strains were indol-positive, serotypes 0:8; 5,27 and 4,32. most of the 242 cultures of nonhuman origin, except those isolated from swine and a few isolated from wild animals, were in ... | 1979 | 535372 |
| epidemiological and clinical aspects of human yersinia enterocolitica infections in belgium. | in the period from 1963 to 1975 data were collected on 1,781 isolates of y. enterocolitica from human infections in belgium. there was an uneven spread of the cases over the country, but this could simply reflect the distribution and activity of medical laboratories. serotype 3 dominated (89.2%) followed by serotype 9 (8.6%). less than 1% of all isolates were from nonenteral sources. gastroenteritis was the diagnosis in 86.8% of patients, while 10.6% were suffering from an appendicitis-like synd ... | 1979 | 535373 |
| yersiniosis in california. | thirty-three strains of yersinia enterocolitica representing 11 different serotypes were identified from human isolates in california between 1968 and mid-1977. the most frequently encountered serotype, 0:5,27, was identified in 8 cases. twenty-one strains, representing five serotypes, were esculin- and salicin-negative, and were considered to be the primary cause of disease in the majority of these cases. the remaining strains, representing six serotypes, were esculin- and salicin-positive, and ... | 1979 | 535374 |
| the first isolation of human yersinia enterocolitica in brazil: case report. | the isolation of yersinia enterocolitica from humans in brazil has never been described before. the present report describes the isolation of an y. enterocolitica isolate from a patient with clinical symptoms resembling appendicitis. the isolate showed typical sensitivity to the drugs and biochemical tests, with the exception of the motility at 22 degrees c, that was negative. the strain agglutinated with antisera 03 and the patient's serum showed an antibody titer of 1:80 against y. enterocolit ... | 1979 | 535375 |

| waterborne yersinia enterocolitica in the midwest united states. | one hundred forty strains of waterborne y. enterocolitica were isolated from wisconsin and colorado rivers, lakes and wells between october 1974 and march 1976- direct-plating of unconcentrated water specimens on deoxycholate-citrate-mannitol (y-m) agar resulted in 89 isolates. prolonged incubation of specimens in cooked meat broth produced 51 additional strains. most organisms were indole-positive, niléln biotype 1 with 24% belonging to the rhamnophilum subgroup. twenty-three serotypes were rep ... | 1979 | 535377 |
| the first successful isolation and identification of yersinia enterocolitica in iran. | since 1967, more than 2,000 specimens have been examined for the possible existence of yersinia enterocolitica in iran. most of the specimens were stool and appendices. for primary isolation ss and emb media were used and the cultures were incubated at 37 degrees c. in 1976 we isolated the first strain of y. enterocolitica from the stool of a 10-month-old girl. she was suffering from chronic diarrhea. this strain was the first strain of y. enterocolitica to be successfully isolated in iran. it b ... | 1979 | 535378 |
| isolation of yersinia enterocolitica from swine at an abattoir in sweden. | yersinia enterocolitica is presented from a taxonomic point of view. a review about the increased frequencies of isolations of y. enterocolitica from domestic and wild animals in europe is given. recent studies from different countries strongly suggest swine as a source of y. enterocolitica infection to humans. the frequencies of isolation of the o-group i (serotype 3) of this bacteria from swine at a swedish abattoir is presented. the occurrence of positive cases in lots of swine sent to slaugh ... | 1979 | 535379 |
| 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 ... | 1979 | 535380 |
| 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. | 1979 | 535381 |
