Background: Analysis of biomolecules is required in many biomedical research areas. A spectrofluorimetric method is proposed for determination of calf thymus DNA (ctDNA) based on the fluorescence enhancement of terbium-danofloxacin (TbDano) in the presence of ctDNA. Methods: A probe with maximum excitation and emission wavelengths of 347 nm and 545 nm, respectively, was developed. The enhanced ...

The article presents the results of validation screening method for determination quinolone antibiotics residues (enrofloxacin, ciprofloxacin, marbofloxacin, danofloxacin) in tissue samples, egg powder, milk and blood plasma using RIDASCREEN®Chinolone/Quinolones test kits from R-Biopharm (Germany). According to information provided by manufacturer kit, quantitative quinolones content can be car...

Mycoplasma (M.) bovis is frequently implicated in respiratory diseases of young cattle worldwide. Today, to combat M. bovis in Europe, only antimicrobial therapy is available, but often fails, leading to important economical losses. The antimicrobial susceptibility of M. bovis is not covered by antimicrobial resistance surveillance networks. The objectives of this study were to identify resista...

The aim of this study was to characterize 49 Salmonella Enteritidis (SE) isolates from different sources (poultry, human, cow, poultry house environment) in Iran with respect to drug resistance, plasmid profile, and random amplified polymorphic DNA (RAPD) analysis. Antimicrobial susceptibility test to 29 agents found 33 resistance patterns among the isolates. No resistance was observed to danof...

A total of 349 Salmonella enterica subspecies enterica serovar Choleraesuis (S. Choleraesuis) strains, which were isolated between 2008 and 2012 from 349 pigs at two slaughterhouses in Okinawa Prefecture, Japan, were investigated for antimicrobial susceptibility and the presence of antimicrobial resistance genes. All isolates were resistant to at least four antimicrobial agents. The antimicrobi...
