Although several genes that cause monogenie familial cancer syndromes have been identified, susceptibility to sporadic cancer remains unresolved. Animal experiments have demonstrated multigenic control of tumor suscep tibility. Recently, we described four mouse lung cancer susceptibility (Slue) loci, the main effects of which are masked by their mutual interactions. Because such interactions ca...
A rapid, potentially clinically useful test for detection of enterotoxigenic Escherichia coli is described. Whole bacterial cultures of enterotoxigenic E. coli, when briefly exposed to Y1 adrenal cells in tissue miniculture, effect a rounding response in the tissue culture that can be discerned at 18 to 24 h. The tissue culture technique agreed with the rabbit ileal loop in all 58 enterotoxigen...
The incidence and numbers of enterotoxigenic Clostridium perfringens in the intestinal contents of cattle, swine and broiler chickens were determined and compared with those of total (enterotoxigenic and nonenterotoxigenic) C. perfringens. The method used for the enumeration of enterotoxigenic C. perfringens consisted of a combination of the most probable number (MPN) method and a nested polyme...
objective(s): enterotoxigenic escherichia coli (etec) strains are one of the primary causes of diarrhea in newborn calves and in humans, pigs, and sheep. igy technology has been identified as a promising alternative to generating a mass amount of specific antibody for use in immunotherapy and immunodiagnostics. the purpose of this study was to produce specific antibody by egg yolk antibody (igy...
Non-enterotoxigenic bacteria of the Bacteroides fragilis group and enterotoxigenic B. fragilis were identified from children with and without aqueous acute diarrhea. In this study, 170 stool samples from 96 children with and 74 without diarrhea were analyzed. Enterotoxin production and the toxin gene detection were detected by cytotoxicity assay on HT-29/C1 cells and by PCR, respectively. B. fr...
Escherichia coli is a diverse bacterial species which is widely distributed in the environment but also exists as a commensal and pathogen of different host species. Human intestinal pathogenic E. coli causes over 160 million cases of diarrhea and an estimated 1 million deaths per year. The majority of deaths are attributable to one pathovar of E. coli, namely, enterotoxigenic E. coli. The path...
Putative colonization factor PCFO20 was recently identified in an enterotoxigenic Escherichia coli (ETEC) strain of serogroup O20 isolated from a child with diarrhea in Argentina. The gene encoding the structural subunit of PCFO20 fimbriae, fotA, was cloned from strain ARG-2 in the expression phage vector lambda ZAP Express. One positive clone, pGV29, that carried a 3.3-kb fragment was identifi...
The present authors explored the relationship between asthma control status, as measured by a derived Asthma Control Test (ACT) score, and the utilisation and cost of healthcare in Europe. Data were derived from a European survey of asthma patients. Frequency of healthcare resource use was identified from the dataset and per-patient mean cost of asthma management estimated. Drug costs were not ...
This study was carried out in order to investigate the presences of Bacillus cereus and its enterotoxigenic genes in infant foods in Isfahan, Iran. Overall 200 infant foods with various based were collected and immediately transferred to the laboratory. All samples were culture and the genomic DNA was extracted from colonies with typical characters of Bacillus cereus. The presences of enterotox...
Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in travelers, young children and piglets, but the precise pathogenesis of ETEC induced diarrhea is not fully known. Recent investigations have shown that tight junction (TJ) proteins and aquaporin 3 (AQP 3) are contributing factors in bacterial diarrhea. In this study, using immunoblotting and immunohistochemistry analyses, we found that E...
