    Article Title: Is Galleria mellonella model a good alternative to study virulence in Staphylococcus aureus from bovine mastitis?
    Article Snippet: Staphylococcus aureus is one of the agents of bovine mastitis of hardest control due to a complex pathogenesis comprising a variety of virulence factors, which ensures its persistence in the mammary gland, causing significant health and economic losses.. Therefore, understanding the pathogenesis of this agent is imperative.. Galleria mellonella has stood out as an invertebrate animal model for the study of infectious diseases that affect several hosts.

    Article Snippet: The gel was run in 0.5× TBE buffer at 5 V/cm with a linear pulse increase from 1 s to 6 s at 14°C for 14 h with a Bio-Rad Chef DR II pulsed-field electrophoresis system. .. Lambda PFGE marker (New England Biolabs, Inc.) was used for size determination. .. After electrophoresis, the resolved gel was stained with ethidium bromide (EtBr), soaked in 0.25 M HCl and 0.4 M NaOH for 15 min each, blotted onto a Hybond N + membrane (Amersham, Inc.), and hybridized with a 32 P-labeled TR probe (to detect the linear KSHV genome).

    Article Title: Subtyping Brazilian Yersinia pestis strains by pulsed-field gel electrophoresis
    Article Snippet: .. Digested fragments were separated using CHEF-DR III, Bio-Rad system (Countour-Clamped Homogeneous Electric Fields/Bio-Rad) on 1% Seakem Gold agarose (Lonza, Rockland, ME, USA) gels and running buffer of 0.5% TBE at 14°C with a ramping time of 4.5 V/cm for 22 h. Lambda PFGE marker (New England BioLabs, Country RD Ipswich, MA, USA) was the molecular weight standard. .. Ethidium bromide (1 μg/mL)-stained bands were visualized under UV and the images captured by the 1-D Image Analysis Software, version 3.5 (Kodak Digital Science, New Haven, CT, USA).

    Article Snippet: The purpose of this study was to report intraand inter-species spread of carbapenemase genes between gram negative rods isolated from a non-hospitalized patient with bacteremia.. The approach included chart review, antibiotic susceptibility testing and phenotypic screening for metalloβ-lactamase (MBL) detection, PCR and sequencing of bla, aac(6’)-Ib and qnr genes, and plasmid analysis by PCRbased replicon typing.. The clonal relationships between the isolates were analysed by comparing PFGE profiles.

Following proteinase K treatment, plugs were extensively washed in TE2 buffer (10 mM Tris, 2 mM EDTA [pH 8.0]) and incubated overnight at ambient temperature in 1× SureCut buffer supplemented with 15 U of SmaI (New England BioLabs). .. The next day, plugs were loaded into wells of a 1% SeaKem gold agarose gel along with a lambda low-range PFGE marker (New England BioLabs) and run in 0.5× TBE buffer (Tris-borate-EDTA [pH 8.0]) in a CHEF-DR-II apparatus (Bio-Rad Laboratories). .. The migration conditions were 15 h at 14°C and 6 V/cm with a pulse ramp of 5 to 13 s. Following migration, the gel was stained with ethidium bromide, visualized under UV light, and photographed using an ImageQuant 300 gel documentation system (GE Healthcare).
