A total of 190 Dermacentor reticulatus ticks (80 males, 110 females) collected on the territory of Ostrów Lubelski, Suchawa, Zalutyń and Kazimierz Dolny (Lublin Province, eastern Poland) were examined by reverse transcription PCR and nested PCR methods for the presence of hantavirus RNA. None of the examined Dermacentor reticulatus specimens showed the presence of the hantavirus-specific RNA in...

target modification and reduced drug accumulation are the main resistance mechanisms against fluoroquinolone antibiotics in pseudomonas aeruginosa. we performed a genotypic characterization of three major mex multidrug efflux pumps (mexab-oprm, mexxy-oprm and mexcd-oprj) in ciprofloxacin resistant clinical isolates of p. aeru­ginosa, collected from tehran, iran this was followed by sequencing a...

background and aims: canine distemper (cd) is a deadly infectious disease of canidae family. cd is a multi-systemic viral disease and is specified by wide range of clinical symptoms. the manifestations are not always indicative of cd, therefore a laboratory confirmation is necessary for suspected cases. materials and methods: different clinical specimens of 19 cd suspected unvaccinated dogs wer...

Hop stunt viroid (HSVd), a significant pathogen of some hop cultivars, was detected for the first time in hops Australia. Plants were tested graft-transmissible pathogens prior to their use research trials. Upon observing symptoms indicative potential infection, RNA extracted and amplified using reverse transcription polymerase chain reaction (RT-PCR); HSVd identity confirmed by sequencing.
