Studies on avian pathogenic Escherichia coli in commercial broiler chicken in South East Queensland

Abstract: Avian pathogenic Escherichia coli (APEC) is the causative agent of avian colibacillosis, a localised or systemic infection resulting in clinical diseases such as colisepticemia, chronic respiratory disease and swollen-head syndrome. Globally, avian colibacillosis is the leading cause of morbidity and mortality in poultry, and it has been associated with massive economic losses and welfare problems.This organism is of public health significance as APEC is communicable to humans. The diagnosis of avian colibacil… Show more

“…This sample is of an ST which was reported in a study on FQR E. coli from canine faeces and cases of human ExPEC infection as a dominant lineage between both such sources [ 74 ], and therefore these gyrA / parC mutations are probably clonal. Additionally, analysis of APEC and Avian faecal E. coli (AFEC) in Australia identified strains of ST354 with FQR [ 75 ]. Otherwise, the APEC in our collection did not carry genes conferring resistance to antimicrobials important in the treatment of human disease, including cephalosporins, fluoroquinolones, carbapenems and colistin, an observation in stark contrast to those made on APEC isolated in many other countries.…”

“…Almost all 95 APEC carried the increased serum survival gene iss (91/95, 96 %), ompT (91/95, 96 %) and traT (90/95, 95 %), genes that have been epidemiologically associated with or determined experimentally to confer serum resistance in ExPEC [ 94–97 ]. A recent study on 50 Australian APEC reported identical carriage rates of iss and ompT [ 75 ]. The importance of the iss gene as a marker of APEC is reinforced by its inclusion in a diagnostic pentaplex PCR [ 37 ].…”

“…In addition, [ 75 ] reported that there were fewer changes in microbial populations in the large intestine of animals than those in the small intestine due to their competition with the host for nutrients [ 76 ]. Moreover, E. coli is considered to be a part of the cecal microbiome and may become a pathogenic agent due to stress, poor welfare, host factors, or as a secondary infection [ 77 ]. Furthermore, E. coli may function as a reservoir for T3 by binding it to bacterial thyroid-binding hormone [ 78 ].…”

“…PCR primers targeting virulence genes for APEC characterization were used as per the literature (Johnson et al 2008;Awawdeh 2018) for detection of ve virulence genes (Table 2). The PCR was rst performed separately for each virulence gene as described by Johnson et al (2008) using APEC O2 as a positive control available in the department.…”

“…Previous studies have suggested that virulence factors are responsible for the pathogenicity of APEC (Dou et al 2015). Although there are several virulence factors related to the extraintestinal pathogenicity of APEC, hlyF, ompT, iroN, iss, and iutA carried on colV plasmid are considered as the most signi cantly associated with APEC strains and are widely used for characterization (Johnson et al 2008;Dou et al 2015;Awawdeh, 2018).…”
