A fluoroquinolone induces a novel mitogen-encoding bacteriophage in Streptococcus canis.
This study investigated whether the recently recognized emergence of canine streptococcal toxic shock syndrome (STSS) and necrotizing fasciitis (NF) might be partly attributed to the use of fluoroquinolones to treat Streptococcus canis infections in dogs. Both mitomycin and the fluoroquinolone enrofloxacin caused bacteriophage-induced lysis of S. canis strain 34, an isolate from a case of canin...
متن کاملbacteriophage as a novel antibacterial agent in industry and medicine
bacteriophage is a kind of virus that infect bacteria, and is distinct from the animal and plant viruses that could have either lytic or lysogenic cycle. lytic phages known as candidates for phage therapy, since they rapidly replicate into their host and lyse them. theoretically, phages have more than a few benefits over routine antibiotics. they are extremely specific and for their targeted ho...
متن کاملFluoroquinolone-resistant Streptococcus pneumoniae
To the Editor: In pneumococci, resistance to fluoroquinolones is associated with chromosomal mutations in the quinolone-resistance–determining regions (QRDR) of type II topoiso-merase enzymes, predominantly gyrA and parC. Several mutations have been described in these enzymes, but only a few have been shown by in vitro studies to confer resistance: S81F or Y, C, or I and E85K in gyrA; E474K in ...
متن کاملFluoroquinolone resistance in Streptococcus pyogenes.
Streptococcus pyogenes isolated from blood and urine samples obtained from a 78-year-old woman was tested for susceptibility, and fluoroquinolone resistance (minimum inhibitory concentration of levofloxacin, 16 microg/mL) was found. DNA amplification and sequencing revealed a serine81-->tyrosine substitution in gyrA and 2 substitutions in parC: serine79-->phenylalanine and alanine121-->valine. ...
متن کاملStudies on Streptococcus Bacteriophage
A series of experiments was carried out on various strains of streptococci in order to ascertain the changes which bacteriophage produces in the phenomena of agglutination of these organisms. The results can be placed in the following categories. 1. Loss of specific agglutinability was observed with partial and with what appeared as complete loss of specific agglutinin absorption and agglutinog...
