Aminopeptidase activities of Propionibacterium freudenreichii dairy isolates
This study was undertaken to achieve more information on the aminopeptidase activities expressed in Propionibacterium freudenreichii strains naturally occurring in milk and dairy products. Fifty four strains belonging to both subspecies freudenreichii and shermanii were analyzed for activity towards different amino acyl β-naphthylamide (βNA) derivatives. The ability to efficiently hydrolyze ami...
متن کاملCharacterization of a Multidrug-Resistant Salmonella enterica Serovar Heidelberg Outbreak Strain in Commercial Turkeys: Colonization, Transmission, and Host Transcriptional Response
In recent years, multidrug-resistant (MDR) Salmonella enterica serovar Heidelberg (S. Heidelberg) has been associated with numerous human foodborne illness outbreaks due to consumption of poultry. For example, in 2011, an MDR S. Heidelberg outbreak associated with ground turkey sickened 136 individuals and resulted in 1 death. In response to this outbreak, 36 million pounds of ground turkey wer...
متن کاملLipase and Esterase Activities of Propionibacterium freudenreichii subsp. freudenreichii.
The lipase and esterase activities of eight strains of dairy Propionibacterium freudenreichii subsp. freudenreichii were studied. A lipase activity was detected on whole cells and in the culture supernatant. The highest activity was expressed at 45 degrees C and pH 6.8. An esterase activity was also detected in the culture medium. The electrophoresis of the intracellular fractions of the cells ...
متن کاملOccurrence of multidrug-resistant Salmonella enterica serovar Enteritidis isolates from poultry in Iran
Salmonella enterica is recognized as one of the major food-borne pathogens with more than 2,500 serotypesworldwide. The present study addresses antimicrobial resistance of Salmonella enterica serovar Enteritidisisolates in Iran. A collection of 151 Salmonella spp. isolates collected from poultry were serotyped toidentify Salmonella Enteritidis. Sixty-one Salmonella Enteritidis were subsequently...
متن کاملFilamentous phage active on the gram-positive bacterium Propionibacterium freudenreichii.
We present the first description of a single-stranded DNA filamentous phage able to replicate in a gram-positive bacterium. Phage B5 infects Propionibacterium freudenreichii and has a genome consisting of 5,806 bases coding for 10 putative open reading frames. The organization of the genome is very similar to the organization of the genomes of filamentous phages active on gram-negative bacteria...
