Plasmid Curing Activity of Five Plant Extracts on Multiple Resistant Plasmid Bearing Klebsiella Pnumoniae Strains

ABSTRACT The curing of five medicinal plant extracts (Satureia hortensis, Glycyrrhiza glabra, Teucrium Pollium, Myrtus Communis, Eukalypetus globolus) on plasmid bearing strains of klebsilla pnenmoniae resistance to multiple antibiotics were investigated. Alcoholic and maceration extraction were carried out from leaves, fruits or roots of the above plants. Mimimum inhibitory concentrations (MI...

Plasmid carriage can limit bacteria–phage coevolution

Coevolution with bacteriophages is a major selective force shaping bacterial populations and communities. A variety of both environmental and genetic factors has been shown to influence the mode and tempo of bacteria-phage coevolution. Here, we test the effects that carriage of a large conjugative plasmid, pQBR103, had on antagonistic coevolution between the bacterium Pseudomonas fluorescens an...

Plasmid-to-plasmid recombination in Haemophilus influenzae.

No recombination between plasmids was observed after conjugal transfer of a plasmid into a cell carrying another plasmid. Two types of such recombination took place after transformation, one type being Rec+ dependent and suggesting a preferred site of recombination. The other much rarer type was at least partially Rec+ independent.
