The PB2 protein of influenza A viruses has been shown as host range determinant. In this study PB2gene of five H9N2 isolates from Tehran province during the period of 1998-2001 were partially amplifiedand sequenced to do phylogenetic study. Iranian isolates could be classified in Eurasian lineage according totheir PB2 gene sequences. The PB2 genes of these isolates are different from those of M...
carnation etched ring virus (cerv) is a member of the caulimovirus genus of the caulimoviridae. the virus is the second most important virus of carnation around the world and the only dna virus among infecting viruses of carnation. the virus infected plants were collected from greenhouse in chenaran and two fragments of ~1500 bp and ~1000 bp respectively for coat protein and movement protein we...
The genus Ceratrimeria Bӧrner, 1906 (Collembola: Neanuridae, Pseudachorutinae) in the fauna of Japan
Two Japanese species, Ceratrimeria takaoensis (Kinoshita, 1916) and C. yasumatsui (Uchida, 1940), were redescribed based on fresh material, including that from the type localities using modern morphological criteria. The main diagnostic characters of genus are also discussed. In addition, nucleotide sequences mitochondrial cytochrome c oxidase subunit 1 16S ribosomal RNA genes specimens obtaine...
30 milled rice samples were collected from retailers in four states of Malaysia. These samples were evaluated for Eurotium spp. contaminations by direct plating on malt extract salt agar (MESA). All Eurotium were isolated and identified based on morphology and nucleotide sequences of internal transcribed spacer 1 (ITS1) and ITS2 of the rDNA. Four Eurotium species (E. rubrum, E. amstelodami, E....
Chicken anemia virus was detected by PCR in tissue samples collected from poultry flocks in Gujarat,India. The VP1, VP2 and VP3 gene sequences of CAV from Anand, Gujarat were obtained after cloning thePCR products in pDrive cloning vector. Nucleotide sequence alignment with other CAV sequencesdemonstrated overall identity of 95-98.8%, 98.8-99.8% and 98.8-100% for VP1, VP2 and VP3 regions,respec...
