Contact-haemolysin production by entero-invasive Escherichia coli and shigellae.
Entero-invasive Escherichia coli (EIEC) and shigellae were tested for contact-haemolysin (CH) with red blood cells (RBCs) of guinea-pig, rabbit, rat, mouse, monkey, man, sheep and chicken; all bacteria showed the best lysis with guinea-pig RBCs. The best culture medium for CH activity of shigellae was tryptic soy broth, and for EIEC it was casamino acid-yeast extract broth with 1 mM CaCl2. CH p...
متن کاملEndoscopic Fistulotomy Heals a Y-Shaped Entero-Entero-Cutaneous Fistula
Patients may develop fistulas due to Crohn's disease or as a postoperative complication after restorative proctocolectomy with ileal pouch anal anastomosis. Unfortunately, the treatment of fistulas can be challenging. The current standard of care may include medical therapy and/or surgical intervention. However, endoscopic treatment for postoperative pouch complications has emerged as a valid a...
متن کاملGlycomacropeptide Reduces Intestinal Epithelial Cell Barrier Dysfunction and Adhesion of Entero-Hemorrhagic and Entero-Pathogenic Escherichia coli in Vitro
In recent years, the potential of glycosylated food components to positively influence health has received considerable attention. Milk is a rich source of biologically active glycoconjugates which are associated with antimicrobial, immunomodulatory, anti-adhesion, anti-inflammatory and prebiotic properties. Glycomacropeptide (GMP) is the C-terminal portion of kappa-casein that is released from...
متن کاملEscherichia coli Y family DNA polymerases.
DNA damage is ubiquitous, arising from both environmental and endogenous sources. All organisms have evolved multiple pathways to respond to DNA damage and maintain genomic integrity. Escherichia coli possesses two DNA polymerases, pol IV and pol V, that are members of the Y family. These polymerases are characterized by their specialized ability to copy damaged DNA as well as their relatively ...
متن کاملY-family DNA polymerases in Escherichia coli.
The observation that mutations in the Escherichia coli genes umuC+ and umuD+ abolish mutagenesis induced by UV light strongly supported the counterintuitive notion that such mutagenesis is an active rather than passive process. Genetic and biochemical studies have revealed that umuC+ and its homolog dinB+ encode novel DNA polymerases with the ability to catalyze synthesis past DNA lesions that ...
