Introduction

Hazem Ramadan is currently an Associate Professor of Zoonoses, Hygiene and Zoonoses Department, Faculty of Veterinary Medicine, Mansoura University, Egypt. Dr. Ramadan obtained his bachelor in Veterinary Sciences from Faculty of Veterinary Medicine at Mansoura University, Mansoura, Egypt and appointed as Demonstrator of Zoonoses (November 2005). He obtained his Master degree (2009) and PhD (2013) in Zoonotic and Infectious Diseases from Mansoura University. Dr. Ramadan’s research interest is concerned with One Health and the genetic diversity of antimicrobial resistant bacteria among humans and animals, and how these resistance determinants disseminated from animals to humans. He contributed and authored more than 14 international publications in relevance to his research area of interest.

Aeromonas hydrophila from marketed mullet (Mugil cephalus) in Egypt: PCR characterization of β-lactam resistance and virulence genes.

J Appl Microbiol 2018 Jun 7;124(6):1629-1637. Epub 2018 Mar 7.

Food Hygiene and Control Department, Faculty of Veterinary Medicine, Mansoura University, Mansoura, 35516, Egypt.

Aims: Aeromonas hydrophila has been isolated from various fish species in Egypt and is known to carry virulence and antimicrobial resistance genes, which pose a risk for public health. The aim of the present study is to report, for the first time, the infection of mullet (Mugil cephalus) with A. hydrophila and to clarify the potential association between antimicrobial resistance and virulence traits encoded in A. hydrophila.

Methods And Results: In this study, the occurrence of A. hydrophila in marketed mullet and the antimicrobial resistance phenotypes of these isolates were determined. Aeromonas hydrophila isolates were screened for the presence of virulence and ?-lactam resistance genes; the correlation between both gene groups was also investigated. The infection rate of examined mullet with A. hydrophila was 37% (50/135). The highest antimicrobial resistance was detected to cefoxitin (100%), followed by ampicillin (84%), ceftazidime (56%) and cefotaxime (40%). Only 4% of the isolates were resistant to erythromycin; 6% were resistant to both gentamicin and kanamycin with no resistance to ciprofloxacin. Variable frequencies of virulence and ?-lactam resistance genes were evident from PCR, where aerA and bla predominated. The study also indicated a general weak positive correlation (R = 0·3) between both virulence and ?-lactam resistance genes. Some of the studied virulence genes (e.g. aerA:hlyA and hlyA:ast) were found to correlate positively.

Conclusions: The presence of virulence and resistance genes in A. hydrophila from food sources poses a serious threat to public health. To our knowledge, this is the first report describing the occurrence of A. hydrophila in mullet and highlighting the coexistence of virulence and ?-lactam resistance genes encoded by these bacteria.

Significance And Impact Of The Study: These data provide insights into the potential association of antimicrobial resistance and virulence genes in A. hydrophila from marketed mullet in Egypt, which could pose threats to humans even if a weak positive correlation exists between both genes.
