Hemolytic activity in enterotoxigenic and non-enterotoxigenic strains of Escherichia coli [PDF]

Journal of Clinical Microbiology, 1980
We screened 223 strains of Escherichia coli belonging to serotypes previously associated with the production of enterotoxin for hemolytic activity, using horse erythrocytes in liquid and in agar media. Thirty-eight were hemolytic. They belonged to nine different serotypes; most (65.8%) belonged to one serotype, O6: H-. Additionally, all 38 strains were

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Single Multiplex Polymerase Chain Reaction To Detect Diverse Loci Associated with Diarrheagenic Escherichia coli

Emerging Infectious Diseases, 2003
We developed and tested a single multiplex polymerase chain reaction (PCR) that detects enterotoxigenic, enteropathogenic, enteroinvasive, and Shiga-toxin–producing Escherichia coli. This PCR is specific, sensitive, and rapid in detecting target isolates

Tannins extract from Galla Chinensis can protect mice from infection by Enterotoxigenic Escherichia coli O101

BMC Complementary Medicine and Therapies, 2021
Background Enterotoxigenic Escherichia coli (ETEC) is classically associated with acute secretory diarrhea, which induces 2 million people death in developing countries over a year, predominantly children in the first years of life.

Heat-stable enterotoxins of enterotoxigenic Escherichia coli and their impact on host immunity [PDF]

, 2019
Enterotoxigenic Escherichia coli (ETEC) are an important diarrhea-causing pathogen and are regarded as a global threat for humans and farm animals. ETEC possess several virulence factors to infect its host, including colonization factors and enterotoxins.

Enterotoxigenic Escherichia coli strains belonging to a new serogroup, Escherichia coli O166 [PDF]

Journal of Clinical Microbiology, 1985
Thirty-two strains of Escherichia coli belonging to a new O group, O166, were examined. Twenty-one strains had the flagella antigen H27, five had the H15 antigen, five had the H7 antigen, and one was nonmotile. All the H27 strains and the nonmotile strain produced heat-stable enterotoxin but not heat-labile enterotoxin. All the H7 strains produced heat-

Krisanaklan Reduces Intestinal Anion and Fluid Secretion Through Inhibition of Na+/K+‐ATPase and K+ Channel Activity

Annals of the New York Academy of Sciences, EarlyView.
Krisanaklan reduces CFTR‐dependent intestinal chloride and fluid secretion by inhibiting the Na+,K+‐ATPase and K+ channels in epithelial cells. Consequently, this natural, plant‐derived product may limit secretory diarrhea caused by a diverse array of microbial pathogens. However, by dissipating the transmembrane Na+ gradient, Krisanaklan also inhibits

Prevalence of enterotoxigenic and Shiga toxin-producing Escherichia coli in pigs slaughtered in Mato Grosso, Brazil

Journal of Infection in Developing Countries, 2010
Introduction: This study aimed to estimate the prevalence of enterotoxigenic Escherichia coli (ETEC) and Shiga toxin-producing Escherichia coli (STEC) strains in pigs slaughtered in abattoirs located in the state of Mato Grosso, Brazil.

Treated wastewater used in fresh produce irrigation in Nsukka, Southeast Nigeria is a reservoir of enterotoxigenic and multidrug-resistant Escherichia coli

Heliyon, 2020
Background: Occurrences of pathogens in environmental and irrigation waters, as well as the use of inadequately treated sewage for fresh produce constitute potential public health threats worldwide.

Prevalence of enterotoxigenic Escherichia coli strains harboring the longus pilus gene in Brazil [PDF]

, 2002
The longus type IV pilus gene (IngA) was highly prevalent (32.8%) among Brazilian enterotoxigenic Escherichia coli strains producing both heat-labile and heat-stable enterotoxins and bearing the CFA/I, CS1CS3, or CS6 antigen.
