“…AMPs presented beneficial results in the control of microbial infections and in food supplementation. However, peptides have different functions in the food industry (Bemena et al, 2014 ; Rai et al, 2016 ), and artificial breeding in livestock (Schulze et al, 2014 , 2020 ; Speck et al, 2014 ; Shaoyong et al, 2019 ).…”

“…These peptides were tested for boar semen preservation, indicating that cyclic hexapeptides can be promising candidates, due to proteolytic stability, capacity to control bacterial proliferation, and synergistic interaction with conventional antibiotics. The peptide ε-PL also showed effective results at a low concentration (0.16 g. L −1 ), suggesting that it could be a possible substitute for gentamicin to enhance sperm quality parameters, sperm capacitation, and in vitro fertilization by reducing bacterial concentrations (Shaoyong et al, 2019 ).…”

Antimicrobial Peptides Controlling Resistant Bacteria in Animal Production

In the last few decades, antimicrobial resistance (AMR) has been a worldwide concern. The excessive use of antibiotics affects animal and human health. In the last few years, livestock production has used antibiotics as food supplementation. This massive use can be considered a principal factor in the accelerated development of genetic modifications in bacteria. These modifications are responsible for AMR and can be widespread to pathogenic and commensal bacteria. In addition, these antibiotic residues can be dispersed by water and sewer water systems, the contamination of soil and, water and plants, in addition, can be stocked in tissues such as muscle, milk, eggs, fat, and others. These residues can be spread to humans by the consumption of water or contaminated food. In addition, studies have demonstrated that antimicrobial resistance may be developed by vertical and horizontal gene transfer, producing a risk to public health. Hence, the World Health Organization in 2000 forbid the use of antibiotics for feed supplementation in livestock. In this context, to obtain safe food production, one of the potential substitutes for traditional antibiotics is the use of antimicrobial peptides (AMPs). In general, AMPs present anti-infective activity, and in some cases immune response. A limited number of AMP-based drugs are now available for use in animals and humans. This use is still not widespread due to a few problems like in-vivo effectiveness, stability, and high cost of production. This review will elucidate the different AMPs applications in animal diets, in an effort to generate safe food and control AMR.

“…Puig-Timonet et al (2018) found that both peptides 3 mM concentration did not impair the viability and motility of the spermatozoa and were able to control microbial growth to some extent. Similarly, ε-Polylysine (40 to 128 mg/mL) was shown for effectively inhibiting bacterial growth, improving sperm quality and in vitro fertilization, being able to replace 50% of the gentamicin used in the extender (Shaoyong et al, 2019a).…”

How to cite: Santos CS, Silva AR. Current and alternative trends in antibacterial agents used in mammalian semen technology. AbstractThe use of antibacterial substances as additives in extenders for ensuring the sanitary quality of the semen employed in reproductive biotechniques and preserving it from bacterial deterioration has been reported since the mid-twentieth century. However, the deleterious effects of these drugs on the sperm quality as well as their effectiveness in controlling bacterial growth in the preserved semen have been questioned. The aim of this review was to report the antimicrobials primarily used in the extenders added to the semen of mammals, and to present alternatives to their use. Among the various mammalian species, there is a large variation regarding the antimicrobial types added to semen extenders as cephalosporins (ceftiofur, cefdinir, eg) and quinolones (ofloxacin, ciprofloxacin), alone or in combination with large action spectra substances as penicillin-streptomycin and gentamicin-tylosin-lincomycin-spectinomycin. To combat problems related to bacterial resistance to these drugs, the emergence of alternatives is increasingly evident. Among these alternatives, use of physical methods as centrifugation and filtration, as well as the use of antimicrobial peptides and other substances from different origins have been highlighted for presenting antimicrobial potential.

Fruit decay and deterioration in overall quality are the main problems of preserving peaches after they are harvested. In this article, the outcomes of 1‐MCP combined with polylysine atomization on Xinjiang flat peaches were evaluated. Distilled water atomization treatment, 1,000 mg/L polylysine atomization treatment for 10 min and 1,000 mg/L polylysine atomization treatment for 20 min were employed. Results showed that the combined treatment using 1‐MCP and polylysine helped to delay the fruit decay rate, respiration, ethylene production, respiration intensity, organic acids, soluble solids, hardness, and microorganisms. Furthermore, reactive oxygen metabolism of O2− and OH− was inhibited. A combined treatment can effectively improve the antioxidant capacity during almond storage, and thus improve shelf life. Therefore, 1‐MCP combined with polylysine atomization treatment is necessary to control fruit rotting and to extent the storage life.
