Rapid antigen and antibody, serological tests, and RT ‑ PCR-based molecular methods are widely used for the detection of microorganisms worldwide. Objectives: This study aimed by Isothermal nucleic acid amplification techniques to detect the covid-19. Methods: In this study, 200 samples of nasopharynx and oropharynx were collected from Jamaran Heart Hospital in Tehran. Covid -19 was exami...

during 2009-10, real time rt-pcr and conventional rt-pcr techniques used for detecting btvs rna in 310 blood samples. for real time and gel based rt-pcr segment-1 and segment-10 selected as conserve genes to search any btv strains. using these methods, 58 (%18.7) and 14 (%4.5) positive samples were detected among the clinically suspected sheep. sensitivity of both molecular techniques evalua...

Viral myocarditis is a moderate disease, but it sometimes causes progressive cardiac disorder. Many different viruses have been considered as the agent of viral myocarditis, but Coxsackievirus of the B group, in particular of the Coxsackievirus B3 (CVB3), is more than fifty percent of cases of viral myocarditis. CVB3 is a positive single-stranded RNA virus and a member of the genus Enterovirus ...

Tuberculosis genotyping data are frequently used to estimate the proportion of tuberculosis cases in a population that are attributable to recent transmission (RT). Multiple factors influence genotype-based estimates of RTand limit the comparison of estimates over time and across geographic units. Additionally, methods used for these estimates have not been validated against field-based epidemi...
