outbreaks causing mass mortalities have been observed in the golden grey mullet (liza auratus) population in southern coastal area of the caspian sea since 2002. the clinical signs include neurological abnormalities, such as erratic swimming behavior, spiral swimming, belly-up at rest and over inflation of the swim bladder. three hundred and twelve samples of moribund fish with sizes that range...

Nowadays, most nucleic acid detections using fluorescent probes rely on quenching of fluorescence by energy transfer from one fluorophore to another or to a non-fluorescent molecule (quencher). The most widely used quencher in fluorescent probes is 4-((4-(dimethylamino)phenyl)azo)benzoic acid (DABCYL). We targeted a nucleoside-DABCYL analogue which could be incorporated anywhere in an oligonucl...

Duplex PCR was developed to screen Salmonella enterica serovar Typhimurium phage type DT104 and related strains in Thailand because a phage typing laboratory of serovar Typhimurium is not available. Of 46 isolates of serovar Typhimurium and 32 isolates of S. enterica serovar 1,4,[5],12:i:-, 15 (33%) and 30 (94%) were duplex PCR positive, respectively. All isolates were submitted for phage typin...

backgrounds and aims: coxsakievirus b3 (cvb3), one of the six coxsakievirus b serotypes, is a member of the enterovirus genus within the picornaviridae family. cvb3 is an important pathogen of viral myocarditis, which accounts for more than 50% of viral myocarditis cases. the genome of cvb3, like that of other entroviruses, is a single-stranded, sense, polyadenylated rna molecule with 7400 nucl...
