Special Issue Information

Dear Colleagues,

One of the main areas that public health has focused on is food safety. Public health deals with hazards in the food supply chain since millions of people fall ill after consuming contaminated food. Cases of foodborne illnesses are continuously reported around the world. Foodborne diseases are caused by pathogens such as bacteria, fungi, parasites, and viruses, and are categorized either into infection or intoxication illnesses. Escherichia coli, Listeria monocytogenes, species of Salmonella or Shigella, Adenovirus, and Cryptosporidium are well-known pathogens that primarily use food products as vehicles of transmission. Therefore, the public health sector needs support regarding foodborne pathogen outbreaks. As foodborne incidents remain a problem for public health, a particular emphasis is placed by scientists on innovative techniques that can be applied in the food industry. Recent developments in “Foodomics” approaches could challenge the existing limitations in the detection of foodborne pathogens.

This Special Issue intends to expand our knowledge on the detection of foodborne pathogens by omics methods, from farm to fork. We specifically welcome studies with novel and alternative omics technologies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pathogens is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This study aimed to detect the virulent Salmonella serovars (including ESBLs producing) isolated from broiler chickens and humans. Three hundred broilers and sixty human fecal samples were bacteriologically examined. Thirty (10%) and fourteen (23.4%) Salmonella isolates were recovered from broiler and human samples, respectively. The most predominant serovar was S. enteritidis and S. typhimurium. All Salmonella isolates were confirmed by conventional PCR-based invA and ompA genes. Multidrug resistant (MDR) isolates were screened for the detection of adrA and csgD biofilm-associated genes, which were found in all isolated serovars except one S. typhimurium and 2 S. infantis of chicken isolates that were devoid of the adrA gene. Moreover, MDR isolates were screened for detection of seven resistance genes including ESBLs and other classes of resistance genes. Chicken isolates harbored blaTEM, int1, blaCTX and qnrS genes as 100, 27.8, 11.1 and 11.1%, respectively, while all human isolates harbored blaTEM, int1 and int3 genes. The genetic correlations between virulent Salmonella serovars (including antimicrobial resistance) avian and human origins were compared. In conclusion, the high prevalence of virulent ESBL producing Salmonella serovars in broilers and humans with genetic correlations between them might be zoonotic and public health hazards.
