Diversity of Streptococcus thermophilus Phages in a Large-Production Cheese Factory in Argentina
(American Dairy Science Association, 2006-12)
Phage infections still represent a serious risk to the dairy industry, in which Streptococcus thermophilus is used in starter cultures for the manufacture of yogurt and cheese. The goal of the present study was to analyze ...
Adsorption of temperate phages of Lactobacillus delbrueckii strains and phage resistance linked to their cell diversity
(Wiley Blackwell Publishing, Inc, 2011-04)
Aims: The aim of this work was to study the adsorption step of two new temperate bacteriophages (Cb1/204 and Cb1/342) of Lactobacillus delbrueckii and to isolate phage-resistant derivatives with interesting technological ...
Streptococcus thermophilus phage monitoring in a cheese factory: Phage characteristics and starter sensitivity
(Elsevier, 2009-08)
Nineteen Streptococcus thermophilus phages isolated from an Argentinean cheese plant were studied regarding their host range, morphology, packaging mechanism and nucleotide sequence of the variable region VR2 (one of the ...
Phage adsorption and lytic propagation in Lactobacillus plantarum: Could host cell starvation affect them?
(BioMed Central, 2015-12)
Background: Bacteriophages constitute a great threat to the activity of lactic acid bacteria used in industrial processes. Several factors can influence the infection cycle of bacteriophages. That is the case of the ...
Virulence of Leuconostoc phages: Influence of stress conditions associated to dairy processes on their host-phage interactions
(Elsevier Science, 2019-05)
In this work, we assessed the impact of technological cell stress conditions, commonly present in industrial dairyprocesses, on the host strain-phage interactions in Leuconostoc. Adsorption and burst size of LDG ...
Characterization of three Lactobacillus delbrueckii subsp. bulgaricus phages and the physicochemical analysis of phage adsorption
(Wiley Blackwell Publishing, Inc, 2004-01)
Aims: Three indigenous Lactobacillus delbrueckii subsp. bulgaricus bacteriophages and their adsorption process were characterized. Methods and Results: Phages belonged to Bradley's group B or the Siphoviridae family ...
Characterization of two virulent phages of Lactobacillus plantarum
(American Society for Microbiology, 2012-12)
We characterized two Lactobacillus plantarum virulent siphophages, ATCC 8014-B1 (B1) and ATCC 8014-B2 (B2), previously isolated from corn silage and anaerobic sewage sludge, respectively. Phage B2 infected two of the eight ...
Use of a regression model to study host-genomic determinants of phage susceptibility in MRSA
(MDPI, 2018-03)
Staphylococcus aureus is a major agent of nosocomial infections. Especially in methicillinresistant strains, conventional treatment options are limited and expensive, which has fueled a growing interest in phage therapy ...
Characterization of a New Virulent Phage (MLC-A) of Lactobacillus paracasei
(American Dairy Science Association, 2006-12)
A new virulent bacteriophage (MLC-A) was recently isolated in Argentina from a probiotic dairy product containing a strain of Lactobacillus paracasei. Observation of the lysate with an electron microscope revealed bacteriophage ...
Effect of high pressure homogenization on lactic acid bacteria phages and probiotic bacteria phages
(Elsevier, 2009-05)
To study the effect of high-pressure homogenization on virus inactivation, phages specific for Lactobacillus delbrueckii, Lactobacillus helveticus, Streptococcus thermophilus, Lactococcus lactis, Lactobacillus paracasei ...
