Isolation and identification of Enterococcus faecium from seafoods: Antimicrobial resistance and production of bacteriocin-like substances

Isolation, Molecular Identification and Antibiotic Resistance of Enterococcus faecalis from Diseased Tilapia

“…Although, the detection of virulence factors may indicate a virulence potential in food isolates, food-borne Enterococcal infection have never been reported (Giraffa, 2002;Foulquie-Moreno et al, 2006;Valenzuela et al, 2010). However, the consumption of food carrying antibioticresistant bacterial populations is considered a possible transfer route (Kruse and Sorum, 1994).…”

Antagonistic Activity, Antimicrobial Susceptibility and Potential Virulence Factors of Enterococcus faecalis

“…Bacteriocin production in isolates from seafood was reported by Valenzuela et al [9] and Pinto et al [24].…”

“…Hemolytic activity and the cylA gene were not observed in a study on E. faecium strains isolated from seafood [9], although Valenzuela et al [5] reported that in 17% of E. faecalis isolates from plants and animals that contained the cylA gene, there was no hemolytic activity.…”

“…Gelatinase is a metalloprotease that hydrolyses gelatin, collagen, hemoglobin and other bioactive peptides. Although this enzyme is related to the induction of inflammatory processes and biofilm production [38][39][40], its proteolytic action is considered advantageous for industry [9].…”

Bacteriocins of Aquatic Microorganisms and Their Potential Applications in the Seafood Industry

“…The identification of harveyicin led to numerous bacteriocin-screening studies in marine bacteria, which focused primarily on biochemical characterization of bacteriocins and bacteriocin-like inhibitory substances (Bagenda et al, 2008;Bhugaloo-Vial et al, 1996;Carraturo et al, 2006;Hosseini et al, 2009;Hoyt & Sizemore, 1982;Longeon et al, 2004;McCall & Sizemore, 1979;Messi et al, 2003;Metivier et al, 1998;Moro et al, 1997;Nilsson et al, 2002;Pinto et al, 2009;Pirzada et al, 2004;Prasad et al, 2005;Rajaram et al, 2010;Selvin et al, 2004;Shehane & Sizemore, 2002;Stoffels et al, 1992;Sugita et al, 1997;Suzuki et al, 2005;Tahiri et al, 2004;Valenzuela et al, 2010;Zai et al, 2009). The majority of these studies focused on the killing breadth of the producing strains due to their potential for use as antimicrobials and probiotics.…”
