Rapid detection and differentiation of infectious bronchitis virus (IBV) involved in the disease outbreak is very important for controlling disease and developing new vaccines. In the present study, three regions of the genome of IBV vaccine and field isolates including S1 gene, gene 3 and nucleocapsid (N) gene along with 3' untranslated region (3' UTR) were amplified and subjected to restricti...

  Background and Objective: Helicobacter pylori has several strains with different degrees of virulence. The aim of this study was to detect two major important virulence factors, cagA/vacA genotypes, and to determine correlations among different cagA/vacA genotypes and histological features of chronic gastritis in Iranian patients. Methods: In this cross- sectional study, Gastric bi...

leptospirosis caused by infection with pathogenic leptospires, which is the most prevalent zoonotic disease in the world. the outer membrane proteins (omps) of pathogenic leptospires such as lipl41 play a crucial role in pathogenesis of this disease. therefore a major challenge to develop an effective vaccine against leptospirosis is application of basic research on the omps of leptospires to i...

RNA quality is critically important for many applications. These include Northern hybridization, cDNA library construction, S1 nuclease mapping, and differential gene expression measurements using microarray technology. Agarose gel electrophoresis is sometimes used to monitor the quality of RNA preparations, but many researchers forego RNA characterization because of the lengthy protocols invol...

Spiroplasma virus 4 (SpV4) is an isometric virus with single-stranded, circular DNA infecting the helical mollicute Spiroplasma melliferum, a honeybee pathogen. Previous studies in our laboratory led to the determination of the base sequence of the SpV4 DNA. Nine open reading frames and three promoterlike sequences (P1, P2, and P3) were identified. An inverted repeat leading to the formation of...
