Calf small intestine receptors for K99 fimbriated enterotoxeginic Escherichia coli

Passive immunity in calf diarrhea: vaccination with K99 antigen of enterotoxigenic Escherichia coli and rotavirus.

Twenty-four pregnant cows were vaccinated intramuscularly with K99 extract from enterotoxigenic Escherichia coli and inactivated rotavirus as follows: six cows were injected with 2 ml of oil-adjuvanted vaccine; six cows were injected with 0.5 ml of oil-adjuvanted vaccine; six cows were injected with 4 ml of aluminum hydroxide-adjuvanted vaccine twice with a four-week interval; and six cows were...

Identification and characterization of mouse small intestine mucosal receptors for Escherichia coli K-12(K88ab).

Adhesion of 3H-labeled Escherichia coli K-12(K88ab) to CD-1 mouse small intestine mucus and brush border preparations, immobilized on polystyrene, was studied. E. coli K12(K88ab) was shown to adhere readily to either crude mucus or brush border preparations, but not to bovine serum albumin. In contrast, the nearly isogenic E. coli K-12 strain, i.e., lacking the K88ab plasmid, did not bind well ...

Confirmed nucleotide sequence of fanF of Escherichia coli K99 fimbriae.

Novel mechanism of P-fimbriated Escherichia coli virulence in pyelonephritis.

U rinary tract infections (UTI) are among the most frequently encountered community-acquired or nosocomial infections. The disease burden of UTI is estimated to be 150 million cases annually worldwide (1). Catheterassociated UTI is the most frequent source of Gram-negative sepsis in hospitalized patients (2). The spectrum of disease in UTI includes cystitis, pyelonephritis, urosepsis, catheter-...

Analysis of a naturally occurring K99+ enterotoxigenic Escherichia coli strain that fails to produce K99.

A spontaneously occurring field isolate of enterotoxigenic Escherichia coli that was genotypically K99+ but phenotypically K99- was analyzed for the reason that it did not express K99. The defect, which was cis active, was located within an area 5' to the first gene required for K99 biogenesis and was the result of the deletion of a single base pair.
