  1. Docic M, Bilkei G. Differences in antibiotic resistance in Escherichia coli, isolated from East-European swine herds with or without prophylactic use of antibiotics. J Vet Med B Infect Dis Vet Public Health. 2003;50:27-30 pubmed
    ..coli and other intestinal bacteria. Thus, imposing greater restrictions on antibiotic use in animal agriculture is likely to reduce but not eliminate the occurrence of resistant isolates. ..
  2. Zimmermann S, Wittenwiler M, Hollender J, Krauss M, Ort C, Siegrist H, et al. Kinetic assessment and modeling of an ozonation step for full-scale municipal wastewater treatment: micropollutant oxidation, by-product formation and disinfection. Water Res. 2011;45:605-17 pubmed publisher
    ..5 log units during sand filtration was observed for TCC while no regrowth occurred for E. coli. E. coli inactivation could not be accurately predicted by the model approach, most likely due to shielding of E. coli by flocs. ..
  3. Helbling D, Ackermann M, Fenner K, Kohler H, Johnson D. The activity level of a microbial community function can be predicted from its metatranscriptome. ISME J. 2012;6:902-4 pubmed publisher
    ..We observed a linear and proportional relationship between the activity level of the transformation reaction and the abundance of its associated encoding transcript down to an E. coli cell density of 0.05% of the population. ..
  4. Richter M, Focks A, Siegfried B, Rentsch D, Krauss M, Schwarzenbach R, et al. Identification and dynamic modeling of biomarkers for bacterial uptake and effect of sulfonamide antimicrobials. Environ Pollut. 2013;172:208-15 pubmed publisher
    ..The EC value for the inhibition of pABA increase was 6.9 ± 0.7 ?mol L(-1) STA, which is similar to that calculated from optical density dynamics indicating that pABA is a direct biomarker for the SA effect. ..
  5. Heitzer A, Mason C, Hamer G. Heat shock gene expression in continuous cultures of Escherichia coli. J Biotechnol. 1992;22:153-69 pubmed
    ..The relative magnitude of the response was found to be both temperature and exposure time dependent, but growth rate independent. Changing medium composition resulted in both different steady and transient state expression levels. ..
  6. Heitzer A, Mason C, Snozzi M, Hamer G. Some effects of growth conditions on steady state and heat shock induced htpG gene expression in continuous cultures of Escherichia coli. Arch Microbiol. 1990;155:7-12 pubmed
    ..From these results a clearly temperature regulated htpG expression during both, steady and transient state growth in continuous culture is evident, which is further significantly affected by the growth condition used. ..
  7. Landini P, Busby S. Expression of the Escherichia coli ada regulon in stationary phase: evidence for rpoS-dependent negative regulation of alkA transcription. J Bacteriol. 1999;181:6836-9 pubmed
    ..Thus, at the alkA promoter, the Ada protein can act as both a positive and negative modulator of the adaptive response to alkylation damage, depending on the cell's physiological state. ..
  8. Müller T, Byrde S, Werlen C, van der Meer J, Kohler H. Genetic analysis of phenoxyalkanoic acid degradation in Sphingomonas herbicidovorans MH. Appl Environ Microbiol. 2004;70:6066-75 pubmed
    ..This suggests a different reservoir and reduced transfer for the genes of the modified ortho-cleavage pathway in Alphaproteobacteria compared with the ones in Beta- and Gammaproteobacteria. ..

    ..Thus, our findings support the idea that environmental heterogeneity may promote maintenance of genetic variation in immune defense, but also suggest that different immune traits might not respond similarly to environmental variation. ..

    ..Our results indicate that CsgD can modulate cellulose biosynthesis through activation of the yoaD gene. In addition, the positive effect of CsgD on biofilm formation might be enhanced by repression of the fecR gene. ..
