The study determined the genetic heterogeneity of Helicobacter pylori isolates from antrum and corpus of the same dyspeptic patients in a Thai population and determined the relationship between the antimicrobial susceptibility (AS) profile (antibiogram) and PCR-restriction fragment length polymorphism (PCR-RFLP) pattern. One hundred and nineteen H. pylori isolates comprising 7 single and 56 pai...

A. hlinku 2, 949 76 nitra, Slovak republic, e-mail: [email protected] AbStrAct The aim of this study was to evaluate the relationship between the polymorphism in the leptin gene and milk production traits in pinzgau and Slovak Spotted cattle. A total of 85 pinzgau and 110 Slovak Spotted cows wer...

DNA looping occurs in many important protein-DNA interactions, including those regulating replication, transcription, and recombination. Recent theoretical studies predict that tension of only a few piconewtons acting on DNA would almost completely inhibit DNA looping. Here, we study restriction endonucleases that require interaction at two separated sites for efficient cleavage. Using optical ...

The aim of this study was to identify SNPs in leptin (LEP), leptin receptor (LEPR) and growth hormone (GH) genes in order to analyze genetic diversity of Slovak Spotted cattle. The total numbers of blood samples were taken from 353 Slovak Spotted cows originating from four farms. Genomic DNA was isolated by phenol-chloroform extraction method and analyzed by PCR-RFLP method. After digestion wit...

This study was performed to determine the genotype and allele frequencies association between leptin gene Sau3AI polymorphism some performance traits in Simmental (n=60) Brown Swiss (n=62) cattle province of Erzurum, Türkiye. Considering population, frequency A 0.87 B 0.13 cattle, 0.94 0.06 cattle. According analysis conducted breed, general averages were found be 5422.4 ± 1901.74 kg for actual...

A chromosomal DNA of Scytalidium lignicolum was digested with Sau3AI. The digest was self-ligated and amplified by inverse PCR procedure using primers designed based on the nucleotide sequences of up- and down-stream regions of an intron present in the scytalidopepsin B gene. Analysis of the nucleotide sequence of PCR product (700 bp) showed that the enzyme is synthesized as a precursor protein...

Flavobacterium psychrophilum, a member of the Cytophaga-Flavobacterium-Bacteroides group, is an important pathogen of salmonid fish. Previous attempts to develop genetic techniques for this fastidious, psychrotrophic bacterium have met with failure. Here we describe the development of techniques for the genetic manipulation of F. psychrophilum and the identification of plasmids, selectable mark...
