The objective of the present research was to develop cinnamon oil nanoemulsions using soy protein isolate and lecithin as food grade natural emulsifiers. For this purpose, stable cinnamon oil nanoemulsion (droplet diameter of 141.2 nm) prepared by ultrasonic emulsification. The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of free and nanoemulsified cin...

The ability of antibiotic resistant E. faecalis and E. faecium isolated from food to form biofilm at different temperatures in the absence or presence of 0.75% glucose was evaluated. A synergistic effect on biofilm at 10 °C, 28 °C, 37 °C and 45 °C and glucose was observed for E. faecalis and E. faecium.

A total of 8,072 gram-positive isolates collected from 69 medical centers among all 9 U.S. Census Divisions during the 2015 SENTRY Antimicrobial Surveillance Program were included. Telavancin had minimal inhibitory concentration (MIC)50 and MIC90 values of 0.03/0.06 μg/mL, respectively, against methicillin-susceptible (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA). Similar activi...

Sir, Since the initial reports of vancomycin-resistant enterococci (VRE) in the late 1980s, increasing numbers of such isolates have been identified in centres in both Europe and the U S A . , 2 In 1998, Fujita et al. were the first authors in Japan to describe the isolation of a vancomycin-resistant strain of Enterococcus faecium from a patient with a urinary tract infection. To date, 10 strai...

In this study, thermal processes were developed for cocoa powder against Salmonella and Listeria monocytogenes in a pilot Radiofrequency (RF) unit validated using their respective surrogates Enterococcus faecium NRRL B-2354 innocua. For 1.0 kg samples, RF heating to 90 °C provided 1.74–1.84 log reduction of E. faecium. A 48 min holding post-RF an additional 3.65 2.24 log10 CFU/g insulated non-i...

Background: The resistance of the bacteria and fungi to the innumerous antimicrobial agents is a major challenge in the treatment of the infections demands to the necessity for searching and fi nding new sources of substances with antimicrobial properties. The incorporation of the essential oils (EOs) in chitosan fi lm forming solution may enhance antimicrobial properties. Howe...

The effects of feeding dehydrated Enterococcus faecium on growth performance, immune response, and cecal microflora in broiler chickens challenged with Escherichia coli K88 were investigated. Two hundred eighty-eight 1-d-old birds were randomly assigned to 4 treatments: negative control birds (N-con) fed a basal diet and not challenged with E. coli K88; positive control birds (P-con) fed a basa...

Background: During the last decade, enterococci have become important nosocomial pathogens, representing the second leading cause of urinary tract infections. This increasing prevalence has been paralleled by the occurrence of multi-drug resistant (MDR) and high-level gentamicin resistant (HLGR) strains. Methods: From September 2005 to 2006, a total of 638 enterococcal isolates were collected ...

Considering the emergence of antibiotic resistance, scientists are interested in using new antimicrobial agents in the treatment of infectious diseases including infections of the enteric systems. Lactic acid bacteria have the great potential to produce antimicrobial compounds that inhibit and control pathogenic bacteria. The aim of this study was to determine the anti-bacterial and anti-adhere...
