This study aims to characterize different Salmonella enterica subsp molecularly. strains (n=49) were isolated from human gastrointestinal cases in the Tolima region and poultry Santander regions using PCR-RFLP, PCR-ribotyping, PCR-SSCP. The band patterns obtained with each technique analyzed by building dendrograms based on Unweighted Pair Group Method Arithmetic mean (UPGMA) method Dice coeffi...

PCR-restriction fragment length polymorphism (PCR-RFLP) and PCR-single-strand conformation polymorphism (PCR-SSCP) analyses were carried out on the 1.6-kb groEL gene from 41 strains of 10 different Salmonella serovars. Three HaeIII RFLP profiles were recognized, but no discrimination between the serovars could be achieved by this technique. However, PCR-SSCP analysis of the groEL genes of vario...

This study was conducted to assess the possible association between polymorphisms of transcription factor 7-like 2 (TCF7L2) gene and obese Iraqi adults. DNA obtained from 158 subjects 142 controls. Two specific PCR fragments were designed incorporate two highly frequent single nucleotide polymorphism (SNP)s within TCF7L2, rs11196208 rs7908486. Both amplified loci genotyped by PCR-single-strand ...

Background: Cellular tolerance to heat stress is mediated by shock proteins (HSPs). The HSPs act as molecular chaperones and are transcribed in response stress. Among different families of these proteins, HSP70 considered be related the development temperature tolerance. Unraveling polymorphism protein genes could a step towards identification genetic markers for selecting heat-tolerant cattle....

PCR-single-strand conformation polymorphism (PCR-SSCP) analysis is a rapid and convenient technique for the detection of mutations and allelic variants. We have adapted this technique for the identification of bacteria by PCR with fluorescein-labeled primers chosen from the conserved regions of the 16S rRNA gene flanking a variable region. The PCR product was denatured, separated on a nondenatu...

The inability to distinguish failures of treatment of Plasmodium falciparum infection from new infections is an important impediment to the evaluation of antimalarial drugs. On the basis of a pilot study utilizing polymerase chain reaction (PCR) single-strand conformational polymorphism (SSCP) analysis to genotype P. falciparum isolates, we sought to confirm that PCR SSCP analysis could reliabl...
