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

Parvimonas micra promotes carcinogenesis of colorectal cancer through phenyllactic acid‐induced DNA damage

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.
Multiomics analysis of the faecal samples from CRC patients found that upregulation of P. micra and PLA was associated with the CRC development. PLA from P. micra via pdhD genes could induce DNA damage via AHR signalling pathway to mediate carcinogenesis.

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-

When protein losing enteropathy persists: A case series of viral and lymphatic‐associated etiologies

JPGN Reports, Volume 7, Issue 2, Page 227-230, May 2026.
Abstract Protein‐losing enteropathy (PLE) is a rare condition that is characterized by loss of plasma protein in the intestines leading to hypoproteinemia with subsequent peripheral edema and possibly anasarca. The pathophysiology of PLE varies depending on the etiology and involves either intestinal mucosal injury or lymphatic system alterations ...

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

Effect of probiotic inocula on the population density of lactic acid bacteria and enteric pathogens in the intestine of weaning piglets [PDF]

, 2007
Because antibiotic resistance occurs in bacteria at an alarming rate, significant research has been focused on finding alternative treatments which do not involve the use of antibiotics.

Evaluation of the immunomodulatory activities of the probiotic strain lactobacillus fermentum UCO-979C [PDF]

, 2019
Lactobacillus fermentum UCO-979C, a strain isolated from a human stomach, was previously characterized by its potential probiotic properties. The UCO-979C strain displayed the ability to beneficially regulate the innate immune response triggered by ...

Intratumoral Microorganisms in Tumors: Current Understanding and Emerging Therapeutic Strategies

MedComm, Volume 7, Issue 5, May 2026.
Tumors are no longer viewed as sterile but dynamic ecosystems harboring low‐biomass intratumoral microbiota. These microbes, derived from gut, oral cavity, or circulation, shape tumorigenesis and therapy response via core mechanisms: immunomodulation (regulating T cells, macrophages), metabolic reprogramming (SCFAs, indoles, bile acids), chronic ...
