Characterization of 43 strains of Rhizobium leguminosarum biovars viciae, trifolii, and phaseoli was performed by two methodologies based on PCR amplification, i.e., PCR DNA fingerprinting of interrepeat sequences and restriction fragment length polymorphism (RFLP) analysis of PCR -amplified chromosomal and symbiotic gene regions. Groupings generated by PCR DNA fingerprinting with either extrag...

BACKGROUND It is clinically important to detect and type human papillomavirus (HPV) in a sensitive and specific manner. OBJECTIVES Development of a nested-polymerase chain reaction-restriction fragment length polymorphism (nested-PCR-RFLP) assay to detect and type HPV based on the analysis of L1 gene. METHODS Analysis of published DNA sequence of mucosal HPV types to select sequences of new...

Ghost crabs (genus Ocypode spp.) found on sandy beaches are susceptible with the loss of an ecotone, making them useful as indicators anthropogenic alteration, such seawall construction. On Sendai Bay Pacific coast Tohoku region northern Japan, three species have been sympatrically observed in recent years: O. stimpsoni, ceratophthalmus, and sinensis. However, these only occur from late summer ...

To detect and identify adenovirus (Ad), we used a combination of PCR and restriction fragment length polymorphism (RFLP) analysis. Nested PCR with two primer sets that hybridize to the conserved region for hexon proteins of 14 prototypes of Ad, Ad serotype 1 (Ad1) to Ad8, -11, -14, -19, -37, -40, and -41, amplified a 956-bp DNA fragment. The amplified fragments from the 14 prototypes were compl...

BACKGROUND & OBJECTIVE Mycobacterium avium has emerged as a major opportunistic pathogen, infecting nearly 50 per cent of HIV/AIDS patients in the western world. There is no report from India regarding the typing profile of M. avium, a potential pathogen, the present study was undertaken to assess the genotypic diversity of Indian M. avium isolates of human origin. METHODS A total of 65 bioch...

BACKGROUND/AIM To develop a novel polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) protocol using a new genomic marker sequence and a novel set of restriction enzymes in order to detect and discriminate 2 Echinococcus species, E. granulosus and E. multilocularis, found in formalin-fixed paraffin-embedded (FFPE) human tissues. MATERIALS AND METHODS DNA was isolated...
