A modified nested polymerase chain reaction (PCR) method for detection of Plasmodium falciparum, P. vivax and P. malariae was combined with a simple blood collection and deoxyribonucleic acid (DNA) extraction method and evaluated in Malaysia. Finger-prick blood samples from 46 hospital patients and 120 individuals living in malaria endemic areas were spotted on filter papers and dried. The simp...

the nested PCr has been used to evaluate the usefulness and efficiency of different Bacillus anthracis spore isolation methods in contaminated soil samples. The best results were obtained using two methods described by Beyer et al. [1] and Cheun et al. [9]. outer and inner pairs of primers were designed from the protective antigen gene of plasmid pXo1 as well as from genes B and C of the capsul...

Respiratory tract infections can be caused by a heterogeneous group of viruses and bacteria that produce similar clinical presentations. Specific diagnosis therefore relies on laboratory investigation. This study developed and evaluated five groups of multiplex nested PCR assays that could simultaneously detect 21 different respiratory pathogens: influenza A virus (H1N1, H3N2, and H5N1); influe...

Background: This study aimed to design and analyze the applicability of an oligonucleotide probe in radioisotope 32P-based dot blot hybridization for detection of hepatitis C virus. Methods: Forty-six of plasma samples were used. The plasma was extracted to obtain viral RNA genome as template for RT-PCR and the amplicon was used for nested PCR. Twenty-four HCV genomes were retrieved from GeneBa...

objective: gbv-c is a virus transmissible via blood transfusion and sexual routes. because of the shared transmission routes in gbv-c and hepatitis b virus (hbv) we have attempted to detect gbv-c in hbsag-positive patients using the more sensitive semi-nested pcr. we used restriction fragment length polymorphism (rflp) to determine genotype. methods: a total of 100 serum samples were collected...

babesiosis is an important tickborne disease in the sheep of iran. objectives: a molecular study was carried out in north khorasan province, iran in 2010-2011, designed to identify babesia spp. infection of both sheep and ticks. methods: ninety sheep from different flocks were clinically examined and blood samples were collected with ixodid  ticks . the collected ticks were separated into 82 ti...

background: chlamydia trachomatis (c. trachomatis) and mycoplasma genitalium (m. genitalium) are considered factors in cervical and ovarian cancer and are associated with flaky cell carcinoma of the cervix. the role of steady infection, leading to chronic inflammation, in the of ovarian cancer has received very little consideration, although a background of pelvic inflammatory disease (pid) is ...

a molecular survey was performed for identification theileria spp in sheep and ticks during from 2010-2011 in fasa and kazeroun areas, fars province, iran. a total of 100 sheep from different flocks were clinically examined and blood samples with ixodid ticks collected. the prepared blood smears from capillary vein of ear were stained with giemsa methods and examined by using light microscope. ...
