Abstract

Avian pathogenic Escherichia coli (APEC) are responsible for significant economic losses in the poultry industry. In this study, a model for investigating the pathogenesis of APEC infections was established. APEC strain CH2 (O78) was marked with the luciferase operon (luxCDABE) using a Tn7 transposon and tissues of experimentally infected chickens were analysed for a correlation between the bioluminescent signal and the number of bacteria. Transposition of the lux operon into the chromosome of the APEC isolate did not affect sensitivity to lytic bacteriophages and there was no effect on virulence in an intratracheal infection model in 1-day-old chicks, although results with a subcutaneous infection model were inconclusive. A correlation between the number of bacteria and the luminescent signal was found in liquid medium, as well as in homogenised heart, liver, spleen and lung of 4-week-old experimentally infected chickens. This study showed that lux could be used for identification of the infecting strain after experimental infection with APEC in poultry. © 2016 Elsevier Ltd
