abstract = {Difloxacin (DIF) belongs to the class of fluoroquinolone
antibiotics that have been intensively used for the
treatment of bacterial infections in veterinary and human
medicine. The aim of this field study was to compare the
effect of manure from DIF-treated pigs and untreated pigs on
the bacterial community structure and resistance gene
abundance in bulk soil and rhizosphere of maize. A
significant effect of DIF manure on the bacterial community
composition in bulk soil was revealed by denaturing gradient
gel electrophoresis (DGGE) of bacterial 16S rRNA gene
fragments amplified from total community DNA. In few
samples, quinolone resistance genes qnrB and qnrS1/qnrS2
were detected by PCR and subsequent hybridization, while
qnrA was not detected. Quantitative PCR revealed an
increased abundance of the integrase gene intI1 of class I
integrons and sulfonamide resistance genes sul1 and sul2 in
DIF manure-treated bulk soil and rhizosphere, relative to
16S rRNA genes, while traN genes specific for LowGC-type
plasmids were increased only in bulk soil. Principal
component analysis of DGGE profiles suggested a manure
effect in soil until day 28, but samples of days 71 and 140
were found close to untreated soil, indicating resilience of
soil community compositions from disturbances by
manure.Keywords},
