The California Leafy Greens Marketing Agreement (LGMA) was adopted in an effort to minimize the risk of contamination of leafy greens with enteric pathogens from a variety of sources, including ground and surface irrigation waters. The LGMA contains standards similar to those established for recreational waters, based on Escherichia coli concentrations. However, no correlation between E. coli a...

Endotoxin lipopolysaccharide (LPS) is the most powerful and effective immunostimulant key virulence factor produced by Escherichia coli (E. coli) accountable for many of inflammatory changes observed during bovine mastitis. In this study, whole-transcriptomic gene in peripheral blood mononuclear cells (PBMCs) stimulated with LPS were compared to control group analyzed RNA sequencing. A total 35...

Keberadaan bakteri escherchia coli menandakan air tersebut sudah tercemar mikroba. Hasil survei pendahuluan yang dilakukan terhadap 2 sampel sumur gali, ditemukan bahwa hasil uji pertama > 2400 per 100 ml dan kedua 210 ml. Ini menunjukkan gali mengandung melebihi nilai ambang batas sesuai dengan Permenkes RI No 32 Tahun 2017. Penelitian ini bertujuan untuk menganalisa kandungan ada di desa B...

background:  one of the most common infections in human is urinary tract infection  (uti)  and  uropathogenic   escherichia  coli   is  one  of  its  major causative agents . uti is extremely common among young women. children under age 5 are also highly at risk. considering the prevalence of this disease, it is necessary  to design  an appropriate  diagnostic  method  for its effective diagnos...

Avian colibacillosis is a costly disease for the poultry industry. The mechanisms of virulence employed by the etiologic agent of this disease remain ill defined. However, accumulated evidence suggests that complement resistance and the presence of the increased serum survival gene (iss) in an avian Escherichia coli isolate may be indicative of its ability to cause disease. This association of ...

INTRODUCTION Vaginitis is one of the most common reasons women visit a gynecologist. Escherichia coli has been isolated from women with vaginitis, but its role as a vaginal infection aetiological agent is controversial. This study aimed to detect virulence genes and determine the antimicrobial susceptibility of E. coli strains isolated from monomicrobial and polymicrobial cultures collected fro...

We investigated the genetic relationships of 54 Escherichia coli O103 strains from humans, animals, and meat by molecular typing of housekeeping and virulence genes and by pulsed-field gel electrophoresis (PFGE). Multilocus sequence typing (MLST) of seven housekeeping genes revealed seven profiles, I through VII. MLST profiles I plus III cover 45 Shiga toxin-producing E. coli (STEC) O103:H2 str...

Avian pathogenic E. coli (APEC) cause disease primarly in poultry; however, the link between APEC and infections in humans is questionable. In this current study, a total of 100 APEC strains isolated from chickens in Delmarva were evaluated for the presence of virulence genes to investigate their zoonotic potential in humans. A total of 28 isolates possessed one Enterohaemorrhagic E. coli (EHEC...

The aim of this study was to perform a current molecular characterization of bovine pathogenic Escherichia coli strains isolated from random samplings in Argentinean dairy farms. Rectal swabs were obtained from 395 (63.7%) healthy and 225 (36.3%) diarrheic calves, belonging to 45 dairy farms in Cordoba Province, Argentina. E. coli isolates were examined for virulence genes (f5, f41, f17, sta, s...
