Multi locus variable-number tandem repeat (MLVA) typing tools improved the surveillance of Salmonella enteritidis Institute of Tropical Medicine KU Leuven
Surveillance of Salmonella enterica subsp. enterica serovar Enteritidis is generally considered to benefit from molecular techniques like multiple-locus variable-number of tandem repeats analysis (MLVA), which allow early detection and confinement of outbreaks. Here, a surveillance study, including phage typing, antimicrobial susceptibility testing and MLVA on 1,535 S. Enteritidis isolates collected between 2007 and 2012, was used to evaluate ...
Identification of lactobacilli isolated from the cloaca and vagina of laying hens and characterization for potential use as probiotics to control Salmonella Enteritidis Research Institute for Agriculture, Fisheries and Food
Aims: To select Lactobacillus strains from laying hens for potential use as probiotic to control Salmonella Enteritidis infection. Methods and Results: One hundred and eighty-six lactobacilli were isolated from the cloaca and vagina of laying hens, and identified at the species level by a polyphasic taxonomic approach. All isolates belonged to the Lactobacillus acidophilus, Lactobacillus reuteri or Lactobacillus salivarius phylogenetic groups, ...
Polyphasic characterization of Salmonella Enteritidis isolates on persistently contaminated layer farms during the implementation of a national control program with obligatory vaccination : a longitudinal study Ghent University Research Institute for Agriculture, Fisheries and Food
Eggshell penetration of hen's eggs by Salmonella enterica serovar Enteritidis upon various storage conditions Research Institute for Agriculture, Fisheries and Food
1. The survival and penetration of Salmonella enterica serovar Enteritidis ( SE) inoculated on the eggshell was examined upon storage for up to 20 d at real-life conditions ( 15 to 25 degrees C and 45 to 75% relative humidity ( RH)). 2. Penetration was assessed by emptying the egg contents and filling the eggs with a selective medium that allowed visualising Salmonella growth on the inside of the shell and membrane complex. 3. The study of ...
Eggshell penetration of various types of hens' eggs by Salmonella enterica serovar Enteritidis Research Institute for Agriculture, Fisheries and Food
Egg weight, shell thickness, number of pores, cuticle deposition, eggshell strength (dynamic stiffness and damping ratio), and the ability of Salmonella enterica serovar Enteritidis (SE) to penetrate the eggshell were determined. Penetration was assessed by filling the eggs with a selective medium that allowed viewing of Salmonella growth on the inside of the shell and membrane complex. After inoculation of each shell with on average 2.71 log ...
