Enterotoxigenic Escherichia coli (ETEC) causes substantial diarrheal morbidity and mortality in young children in countries with limited resources. We determined the phenotypic profiles of 915 ETEC diarrheal isolates derived from Egyptian children under 3 years of age who participated in a 3-year population-based study. For each strain, we ascertained enterotoxin and colonization factor (CF) ex...
Monoclonal antibodies (MAbs) against five putative colonization factors (PCFs), i.e., colonization factor antigen (CFA)/III, coli surface antigen (CS)7 and CS17, PCFO159, and PCFO166 of enterotoxigenic Escherichia coli (ETEC), were produced. Hybridomas (one each) producing specific antibodies against the respective PCFs were selected. All the MAbs reacted with the corresponding fimbriae but not...
Aim This study describes the prevalence of Escherichia coli in frozen chicken meat intended for human consumption with emphasis on their virulence determinants through detection of the virulence genes and recognition of the extended-spectrum β-lactamase (ESBL) encoding genes (blaOXA and blaTEM genes). Materials and Methods A total of 120 frozen chicken meat samples were investigated for isola...
Escherichia coli sfa+ strains isolated from poultry were serotyped and characterized by polymerase chain reaction (PCR) and amplified fragment length polymorphism (AFLP). Isolates collected from 12 Brazilian poultry farms mostly belonged to serogroup O6, followed by serogroups O2, O8, O21, O46, O78, O88, O106, O111, and O143. Virulence genes associated were: iuc 90%, fim 86% neuS 60%, hly 34%, ...
background recently, assessment of the atrial motion and deformation indices obtained via doppler myocardial imaging (dmi) has been proposed as a new method of exploring the atrial function. objective our aim was to assess the right atrial (ra) regional function using myocardial velocities, strain, and strain rate imaging (sri) and compare it with the function of the inter-atrial septum (ias) a...
Abstract Introduction Sarcopenia in cancer may confer negative outcomes, but its prevalence and impact the modern multimodal management of locally advanced breast have not been systematically studied. Method Patients undergoing neoadjuvant therapy surgery for between 2010 2015 were Skeletal muscle index (SMI) lean body mass (LBM) determined. was defined by computed tomography (CT) at L3 as SMI&...
Avian pathogenic Escherichia coli (APEC) cause severe respiratory and systemic disease in poultry yet the nature and consequences of host immune responses to infection are poorly understood. Here, we describe a turkey sub-acute respiratory challenge model and cytokine, cell-mediated and humoral responses associated with protection against homologous re-challenge. Intra-airsac inoculation of tur...
