Genetic diversity among Escherichia coli isolates carrying f18 genes from pigs with porcine postweaning diarrhea and edema disease.

Numai utilizatorii înregistrați pot traduce articole

Multilocus enzyme electrophoresis was applied to detect allelic variation and multilocus genotypes (electrophoretic types [ETs]) among 43 Escherichia coli isolates from weaned pigs suffering from edema disease or from diarrhea. ETs were analyzed in relation to O serogroups and virulence genes (sta,

Diarrhea and gallbladder hydrops in an immunocompetent child with Cryptosporidium infection.

Numai utilizatorii înregistrați pot traduce articole

We report a case of an immunocompetent child who developed gallbladder hydrops during a concurrent diarrheal illness caused by Cryptosporidium parvum. Hepatobiliary disease and chronic cryptosporidial diarrhea is an accepted association in adults with HIV infection but has only once previously been

PCR detection of virulence factor genes in Escherichia coli isolates from weaned piglets with edema disease and/or diarrhea in China.

Numai utilizatorii înregistrați pot traduce articole

Fimbriae, toxins and pathogenicity islands (PAIs) are main virulence factors of the pathogenic Escherichia coli strains. To investigate into their prevalence in clinical E. coli isolates associated with porcine postweaning diarrhea (PWD) and/or pig edema disease (ED), 240 isolates were obtained from

Fimbrial colonisation factors F18ab and F18ac of Escherichia coli isolated from pigs with postweaning diarrhea and edema disease.

Numai utilizatorii înregistrați pot traduce articole

During the last 5 years at least four new types of colonisation factors have been described in association with porcine postweaning diarrhea and edema disease strains of E. coli. Recently, evidence was presented that these fimbrial factors are closely related to each other, and therefore the common

Prevalence of the enteroaggregative Escherichia coli heat-stable enterotoxin 1 (EAST1) gene in isolates in weaned pigs with diarrhea and/or edema disease.

Numai utilizatorii înregistrați pot traduce articole

A total of 476 Escherichia coli isolated from weaned pigs with diarrhea and/or edema disease were screened for the presence of the enteroaggregative E. coli heat-stable enterotoxin 1 (EAST1) gene by polymerase chain reaction (PCR). E. coli strains that carried EAST1 genes were also tested by PCR for

DNA microarray-based identification of serogroups and virulence gene patterns of Escherichia coli isolates associated with porcine postweaning diarrhea and edema disease.

Numai utilizatorii înregistrați pot traduce articole

Escherichia coli strains causing postweaning diarrhea (PWD) and edema disease (ED) in pigs are limited to a number of serogroups, with O8, O45, O138, O139, O141, O147, O149, and O157 being the most commonly reported worldwide. In this study, a DNA microarray based on the O-antigen-specific genes of

Prevalence of a gene encoding adhesin involved in diffuse adherence among Escherichia coli isolates in pigs with postweaning diarrhea or edema disease.

Numai utilizatorii înregistrați pot traduce articole

A total of 604 Escherichia coli strains isolated from weaned pigs with diarrhea or edema disease on 653 swine farms were screened for the presence of the adhesin involved in diffuse adherence (AIDA) gene by polymerase chain reaction (PCR). Escherichia coli isolates that carried AIDA genes were also

The AIDA autotransporter system is associated with F18 and stx2e in Escherichia coli isolates from pigs diagnosed with edema disease and postweaning diarrhea.

Numai utilizatorii înregistrați pot traduce articole

Pathogenic Escherichia coli strains are known to cause edema disease (ED) and postweaning diarrhea (PWD) in piglets. Although the exact mechanisms of pathogenicity that lead to ED-PWD remain to be elucidated, E. coli-borne Shiga-like toxin and adhesion-mediating virulence factors such as F18 adhesin

Inhibitory activities of colicins against Escherichia coli strains responsible for postweaning diarrhea and edema disease in swine.

Numai utilizatorii înregistrați pot traduce articole

The efficacies of colicins E1 and N against Escherichia coli strains responsible for postweaning diarrhea and edema disease, two of the most prevalent disease problems for pigs in the United States, were determined in vitro. These proteins may provide an environmentally sound means for the

Prevalence of fimbial colonization factors F18ab and F18ac in Escherichia coli isolates from weaned piglets with edema and/or diarrhea in China.

Numai utilizatorii înregistrați pot traduce articole

F18ab and F18ac are important fimbrial colonization factors of verotoxigenic Escherichia coli (VTEC) and/or enterotoxigenic E. coli (ETEC) in weaned piglets with edema disease and/or diarrhea. To further investigate their prevalence and correlation to pathogenic E. coli, a duplex PCR, using three

[Genotypic characterization of toxigenic Escherichia coli isolated from pigs with postweaning diarrhea (PWD) and edema disease (ED)].

Numai utilizatorii înregistrați pot traduce articole

The purpose of this work was to characterize 47 Escherichia coli strains isolated from 32 pigs diagnosed with postweaning diarrhea and three pigs with edema disease by PCR. Forty two (95.5 %) of the strains isolated from diarrheic pigs were characterized as enterotoxigenic E. coli (ETEC) and 2 (4.5

Binding of E. coli isolates from pigs with postweaning diarrhea or edema disease to crude intestinal mucin of a weaned pig.

Numai utilizatorii înregistrați pot traduce articole

The presence of the fedA (gene coding F18 fimbriae) and genes coding STa and LTI enterotoxins and verotoxin Stx2v was determined in 30 E. coli strains isolated from weaned pigs with postweaning diarrhea (PWD) and edema disease (ED). The fedA gene was detected in 22 strains (73.3%). It was mostly

Design and evaluation of a multiplex polymerase chain reaction assay for the simultaneous identification of genes for nine different virulence factors associated with Escherichia coli that cause diarrhea and edema disease in swine.

Numai utilizatorii înregistrați pot traduce articole

A multiplex polymerase chain reaction (mPCR) assay was developed for detection and characterization of pathogenic Escherichia coli that cause diarrhea and edema disease in swine. The mPCR assay was designed as a single reaction for detecting 5 different adhesins (K88, K99, 987P, F41, and F18), 3

Virulence and fitness gene patterns of Shiga toxin-encoding Escherichia coli isolated from pigs with edema disease or diarrhea in Germany.

Numai utilizatorii înregistrați pot traduce articole

Fecal Escherichia coli isolates (n = 3,218) from piglets with edema disease or diarrhea were screened for the genes of Stx2 and Stx2 variants. A total of 283 E. coli isolates (8.8%) proved exclusively positive for Stx2e and most of these (85.1%) harbored genes for F18 fimbria. No recognized adhesins

Radiology case of the month. Nausea, vomiting, and diarrhea in a patient with hepatitis C and acquired immunodeficiency syndrome (AIDS). Diffuse, severe gastric-wall thickening, consistent with edema.

The patient is a 42-year-old male with a past medical history of HIV/AIDS (his most recent CD4 count, four months before admission, was 19) and hepatitis C who presented to the Emergency Department complaining of one week of persistent nausea, vomiting, and diarrhea. His admit labs were as follows:
