during the summer of 2004, a survey was conducted to determine the incidence and distribution of beet necrotic yellow vein virus (bnyvv) and its vector (polymyxa betae keskin) in marvdasht, fars province of iran.  a total of 353 root samples were collected randomly as well as 124 samples from plants showing rhizomania- associated symptoms.  the presence of bnyvv in the samples were tested by tr...

OBJECTIVES To assess the diagnostic performance of 11 commercial PR3- and MPO-ANCA ELISA systems (direct, capture and high sensitive [hs] ELISA). METHODS Sera from 90 patients with AAV (GPA, MPA and CSS) and 20 disease controls (SLE; RA) and healthy individuals were tested for the presence of ANCA by IFT and by different ELISAs for the presence of PR3-and MPO-ANCA, respectively. Furthermore, ...

background: the current study was conducted to compare elisa with thin layer chromatography (tlc) methods for diagnosis of morphine in the urine. methods: positive urine samples for morphine confirmed by immunochromatographic strips were collected from the imam reza toxicology laboratory, mashhad university of medical sciences, mashhad, iran in 2012 for the current study. then, the collated uri...

Cloned cDNA copies of the genomic RNA of melon necrotic spot virus (MNSV) have been sequenced and the sizes and locations of predicted viral proteins have been deduced. The genome consists of at least 4262 nucleotides and the positive strand contains three to five open reading frames (ORFs) which may be expressed. The 5' proximal ORF encodes a 29K protein (p29) and terminates with an amber codo...

Carnation (Dianthus caryophylinus) is one of the most popular ornamental flowers worldwide. etched ring virus (CERV), belonging to Caulimovirus genus, second significant on carnation crops around world. CERV particles are isometric, with a diameter 47 nm, which contains double-stranded, circular DNA at length about 7932 kbp as genome. causes necrotic flecks, rings and line patterns leaves. Infe...

Screening of blood and blood products for human immunodeficiency virus (HIV) is routinely performed using the enzyme-linked immunosorbent assay (ELISA), and the results confirmed by western blot (WB). In an effort to identify alternative techniques, two locally prepared test kits were evaluated to determine the performance in comparison to commercial kits. These diagnostic kits were indirect im...
