, inactivation by drying, ultrasound, or irradiation was reported to affect the immunomodulatory properties of different bacteria. For example, IL-8 secretion of HT-29 cells was upregulated by ultrasound inactivation of E. coli Nissle 1917 [ 24 ]. In contrast

The microcalorimetric method has been used to study the effects of cefpiramide and ceftizoxime sodium on the E. coli growth. The results revealed that these two cephalosporins may alter the metabolic way of the E. coli. Moreover, the lethal doses of cefpiramide and ceftizoxime sodium are 2.000 and 0.2000 μg mL−1, respectively. Combining with the relationships between growth rate constant (k), the maximum power output (Pm), the time corresponding to the maximum power output (tm) and cephalosporins concentration (C), one can draw the conclusion that the ceftizoxime sodium has a stronger inhibition effects on the growth of E. coli than that of cefpiramide and they both have the possibility to induce the drug fever.

1 Introduction Escherichia coli as a pathogen in humans and animals is still of significant importance, since E. coli transmission through consumption of raw milk, raw milk dairy products, and minced meat has been repeatedly documented ( EU
To investigate the association of pathogenic Escherichia coli fimbrial adhesins with the development of diarrhoea in piglets of different age groups and to test their relative competitiveness, piglets were orally inoculated with a mixture of E. coli strains harbouring F4, F5, F6, F18 and F41 fimbrial genes. A total of 537 E. coli strains with haemolytic activity were isolated from 36 diarrhoeic piglets. The F4 fimbrial gene was observed in 98.5%, 97.6% and 80.6% strains carrying fimbrial genes isolated from diarrhoeic piglets that were infected at 1, 3 and 5 weeks of age, respectively. These data demonstrate that F4 fimbriae are highly associated with diarrhoea in piglets of all age groups. Interestingly, the F18 fimbrial gene was observed in 2.4% and 25.4% strains carrying fimbrial genes isolated from the 3- and 5-week-old groups, respectively, which confirms that F18 fimbriae are associated with diarrhoea in piglets from late stages of suckling to post-weaning, and are more related to diarrhoea in weaned than in unweaned piglets.
