The aim of this study was to determine the occurrence of enterotoxigenic and enteroaggregative Escherichia coli strains and antibiotic resistance of the isolates in raw milk and unpasteurized cheese. Out of 200 samples of raw milk and 50 samples of unpasteurized cheeses, 96 and 24 strains of E. coli were isolated, respectively. Polymerase chain reaction (PCR) was used to detect the genes encodi...

OBJECTIVE To analyze the relationship between traditional Chinese medical syndromes and fungal pneumonia for moderate and advanced lung cancer patients. METHODS We retrospected 115 moderate and advanced lung cancer patients with different syndromes in traditional Chinese medicine (qi deficiency, yin deficiency, blood deficiency, yang deficiency, blood stasis, phlegm dampness, phlegm heat, dam...

Enterotoxigenic Escherichia coli produce various heat-labile and heat-stable enterotoxins. STb is a low molecular weight heat-resistant toxin responsible for diarrhea in farm animals, mainly young pigs. A previous study demonstrated that cells having internalized STb toxin induce epithelial barrier dysfunction through changes in tight junction (TJ) proteins. These modifications contribute proba...

OBJECTIVES To establish the types of E. coli isolates that are found in river water around Nairobi and to assess the potential risk of use of this water to human health. DESIGN Multiple stratified sampling was carried out. Surface sampling was used in the entire study. SETTING The study was carried out on river waters surrounding Nairobi, Kenya. SUBJECTS Forty Escherichia coli strains iso...

Elaboration of different toxins by enterotoxigenic E. coli has been considered as one of the main virulence factors contributing to the manifestation of disease caused by these microorganisms. Various strategies have been employed to raise antibodies against these toxins as a line of defense. In this study, the 3’ terminus of the gene that codes for the binding subunit of the heat-labile entero...

OBJECTIVE The purpose of the study was to assess the effects of Escherichia coli STa (heat stable) toxin on isolated human myometrial response to oxytocin. METHODS One hundred and sixteen muscle strips were obtained from the lower uterine segment of 42 women undergoing cesarean section at term. Amniotic membranes and decidua were excluded. Uterine contractility in response to cumulative doses...
