Special Issue Information

Dear Colleagues,

Animal health is key to ensuring and enabling global food safety and security and public health.

Understanding the pathogens (bacteria, viruses, and fungi) and studying pathogenicity, the mechanisms of infection, the epidemiology, and the systems-based studies that integrate host/pathogen research are key to the prevention and control of animal diseases. The overall goal of the special Issue is to support research in veterinary microbiology focusing on viral, bacterial, and fungal infections as well as the role of bacteria in food and foodborne diseases. Novel vaccine technology platforms and novel diagnostics for the better and earlier detection of a disease are also other priority research areas. Studies of antimicrobial resistance are also included. All research papers on different areas, e.g., immunology, epidemiology, metagenomics, etc., should be related to microbial disease, food production, and/or foodborne diseases. This Special Issue will focus on novel/new diagnostic tools, the pathogenicity, the mechanisms of infection, the epidemiology, as well as the antimicrobial resistance. The topics of this Special Issue include, but are not limited to:

  1. Presence of ESBL E. coli in ruminants.
  2. Lactococcosis and vibrosis in fish.
  3. Mastitis: the role of St. aureus.
  4. Pestiviruses in ruminants.
  5. Viral diseases in fur animals.
  6. Viral neuroinfections in domestic animals.
  7. SARS-COV-2 in animals and the environment, updated research.
  8. Zoonoses of high importance for public health, e.g., brucellosis: current research in persistence.
  9. Foodborne pathogens and microbiome.
  10. Non-starter lactic acid bacteria in dairy antibiotic resistance, virulence genes, technology, etc.).

The aim of the study was to investigate in vitro the antibacterial activity of 8 commercial drinking water additives against major zoonotic poultry pathogens (Campylobacter spp., Escherichia coli, Salmonella Typhimurium, Staphylococcus aureus and Listeria spp.). We tested two essential oil-based phytogenics (Phyto CSC Liquide B, AEN 350 B Liquid), two acid-based eubiotics (Salgard® liquid, Intesti-Flora), and four blends of essential oils and organic acids (ProPhorceTM SA Exclusive, Herbal acid, Rigosol-N and Eubisan 3000). The antibacterial activity was determined by estimating the minimum inhibitory concentration (MIC) using a microdilution method. The MICs of the products against Campylobacter spp. ranged from 0.071% to 0.568% v/v, in which Herbal acid, a blend rich in lactic and phosphoric acids, also containing thyme and oregano oils, exhibited the highest efficacy (MIC: 0.071% v/v) against all the tested strains. The MICs of the tested products against Escherichia coli ranged between 0.071% and 1.894% v/v. Specifically, the MIC of Rigosol-N, a blend of high concentrations of lactic and acetic acid, was 0.142% v/v for both tested strains, whereas the MICs of Intesti-Flora, a mixture rich in lactic and propionic acid, ranged from 0.284% to 0.568% v/v. The MICs of the products against Salmonella Typhimurium were between 0.095% and 1.894% v/v. Specifically, the MIC of Eubisan 3000, a blend rich in oregano oil, was 0.284% v/v. The MICs against Staphylococcus aureus were between 0.142% and 9.090% v/v. The MICs of Phyto CSC Liquide B, which is rich in trans-cinnamaldehyde, were between 3.030% and 9.090% v/v, showing the highest MIC values of all tested products. Finally, the MIC values of the tested commercial products against Listeria spp. were 0.095% to 3.030% v/v. The MICs of ProPhorceTM SA Exclusive, a highly concentrated blend of formic acid and its salts, were 0.095–0.142% v/v against Listeria spp., while the MICs of AEN 350 B Liquid were between 0.284% and 1.894% exhibiting high Listeria spp. strain variability. In conclusion, all the selected commercial products exhibited more or less antibacterial activity against pathogenic bacteria and, thus, can be promising alternatives to antibiotics for the control of zoonotic poultry pathogens and the restriction of antimicrobial-resistant bacteria.
