White spot syndrome virus (WSSV), the etiological agent of white disease (WSD), is a significant pathogen affecting shrimp farming industry worldwide. generalist mainly infecting decapod crustaceans. The aims this review were to: (1) Re-evaluate and update status reported WSSV host vector species based on methods used when detecting replication transmission to 2) make critical evaluation existi...

introduction: to compare the effects of 0.05% sodium fluoride (naf) mouthrinse, gc tooth mousse and gc mi paste plus on white spot formation inhibition. materials and methods: thirty pairs of extracted human premolars were cut in half mesio-distally with a disc. the teeth were coated with nail varnish, except a part of the buccal and/or lingual enamel, which was used as the test area, and then ...

Objective: One complication of fixed orthodontic treatment in patients with poor oral hygiene is development of demineralized enamel lesions compromising esthetics. This study aimed to review preventive measures and treatment of white spot lesions (WSLs) in patients with fixed orthodontic appliances. Review of Literature: In this review study, PubMed and Google Scholar databases were searched ...

White spot syndrome virus, type species of the genus Whispovirus in the family Nimaviridae, is a large, double-stranded DNA (dsDNA) virus that infects crustaceans. The genome of the completely sequenced isolate WSSV-TH encodes 184 putative open reading frames (ORFs), the functions of which are largely unknown. To study the transcription of these ORFs, a DNA microarray was constructed, containin...

abstract iris yellow spot virus (iysv) is one of the important pathogens of onion in reported countries. host range of this virus is very wide and transmitted by onion thrips (thrips tabaci). in survey that was conducted in summer 2006 in onion fields of mashhad, samples with viral symptoms and high population of thrips have been collected. since the symptoms were similar to iysv, special antis...

White spot syndrome virus (WSSV) is at present a major scourge to worldwide shrimp cultivation. We have determined the entire sequence of the double-stranded, circular DNA genome of WSSV, which contains 292,967 nucleotides encompassing 184 major open reading frames (ORFs). Only 6% of the WSSV ORFs have putative homologues in databases, mainly representing genes encoding enzymes for nucleotide m...

White spot syndrome virus (WSSV), the sole member of the virus family Nimaviridae, is a large double-stranded DNA virus that infects shrimp and other crustaceans. By alignment of three completely sequenced isolates originating from Taiwan (WSSV-TW), China (WSSV-CN) and Thailand (WSSV-TH), the variable loci in the genome were mapped. The variation suggests the spread of WSSV from a common ancest...
