Molecular characterisation of Shiga toxin-producing Escherichia coli O157:H7 isolates from cattle in eastern Turkey
pulsed-field gel electrophoresis virulence genes bovine rectal swabs E. coli strains
2016/12/8
Shiga toxin-producing Escherichia coli (STEC) O157:H7 is an important foodborne pathogen worldwide. In Turkey, little is known about the molecular characteristics of STEC O157:H7 isolates. The aim of ...
Effects of a species-specific probiotic formulation on multiresistant Escherichia coli isolates from the gut of veal calves
lactic acid bacteria antibiotic resistance prevalence gastrointestinal functionality veal calves
2015/6/24
In this study, 254 Escherichia coli isolates from faecal samples of veal calves were evaluated for antimicrobial susceptibility using the disk diffusion method. During the experimental period, six mas...
The survival of Escherichia coli upon exposure to irradiation with non-coherent polychromatic polarized light
bacteria growth light plate count
2015/4/15
The purpose of this work was to examine the influence of non-coherent polarized light upon the growth of Escherichia coli. Experiments were designed to test the main hypothesis that this kind of polyc...
Susceptibility of Escherichia coli, Salmonella sp. and Clostridium perfringensto organic acids and monolaurin
fatty acids monolaurin enteropathogenic bacteria inhibition
2015/3/5
The antimicrobial activity of fatty acids, monolaurin, citric, succinic, fumaric, malic and lactic acid was determined in cultures of two strains of Escherichia coli, three strains of Salmonella sp. a...
Survival of Escherichia coli O157:H7, Listeria monocytogenes 4b and Yersinia enterocolitica O3 in ayran and modified kefir as pre- and postfermentation contaminant
ayran modified kefir E. coli O157
2015/1/28
The survival of Escherichia coli O157:H7, Listeria monocytogenes 4b and Yersinia enterocolitica O3 in traditional yogurt and kefir during fermentation, in ayran (a dairy beverage in Turkey), pasteuris...
CD45RA and CD45RC isoforms expression in weaned pigs vaccinated with non-enterotoxigenic F4ac+ Escherichia coli strain against colibacillosis
weaned pigs vaccination colibacillosis CD45 isoforms CD25 flow cytom
2015/1/26
Since no effective vaccine is available for its immunoprophylaxis, porcine post-weaning diarrhoea (PWD) induced by enterotoxigenic Escherichia coli (ETEC) strains remains an important cause of morbidi...
Gene typing of the colonisation factors F18 of Escherichia coli isolated from piglets suffering from post-weaning oedema disease
oedema disease pig colonisation factors Stx2e toxin PCR
2015/1/26
Production of verotoxin Stx2e and expression of F18 and K88 colonisation factors were investigated in 222 strains of Escherichia coli isolated from weaned piglets. Sixty-two, 30, and 11 of the 129 ver...
Molecular analysis of Escherichia coli O157 strains isolated from cattle and pigs by the use of PCR and pulsed-field gel electrophoresis methods
E. coli O157 cattle pigs virulence marker genes RFLP genetic relatedness
2015/1/26
Fourteen Escherichia coli O157 strains isolated from cattle and pigs in Poland and in Germany were investigated, using PCR, for the genetic markers associated with Shiga toxin-producing E. coli (STEC)...
The use of artificial intelligence (artificial neural networks) to classify the biochemical reactions of Escherichia coli isolates from broilers
Escherichia coli biochemical reactions artificial neural network
2010/9/21
The Escherichia coli is often found in the poultry industry and, many times, its presence in the organism of the animals and/or contaminating the litter of poultry houses don’t cause surprise. On the ...
Profiles of Virulence-associated Genes of Avian Pathogenic Escherichia coli Isolates from Chickens with Colibacillosis
APEC broilers molecular detection virulence genes
2009/7/29
The colibacillosis caused by avian pathogenic E.coli (APEC) is responsible for a significant loss of productivity and mortality in the poultry industry. The pathogenicity of these bacteria is based on...
不同猪种肠毒素大肠杆菌（ETEC）F4受体微卫星标记遗传差异性研究The Genetic Variation of Two Microsatellite Markers of Escherichia coli F4(K88) Receptor in Different Swine Breeds
ETEC 微卫星 基因杂合度 Shannon信息指数 遗传标记
2008/1/10
摘要采用13号染色体上与K88ab和K88ac受体基因连锁的2对引物（S0223和S0068），研究沙子岭猪和大约克猪的遗传差异性。结果表明，2个猪种在2个基因座均存在多态性，其基因杂合度和Shannon信息指数存在很大差异，而中外猪种的K88ab和K88ac受体基因也存在遗传差异，这2对引物可望作为K88ab和K88ac受体基因的遗传标记。Abstract: The genetic variat...
