A permanently high virulence was found in tachyzoites of T. gondii K24 after serial passage in mice (90 passages during 324 days). Virulence tests revealed that a single tachyzoite of the 50th passage represented LD100 for mice. Analysis of genotype of K24 isolate was done by PCR/RFLP with ROP1/Ddel, SAG1/Ddel, 850/Rsal and IGS/Rsal and by RFLP/DNA with TGR1E sequence and Pstl enzyme. K24 isola...
PCR-restriction fragment length polymorphism (RFLP) analysis of a 960-bp fragment of the Campylobacter gyrB gene with either DdeI or XspI restriction enzymes generated unique digestion patterns for 12 different Campylobacter species. In addition, PCR assays using species-specific primer sets targeting gyrB were specific for the respective Campylobacter species. Therefore, PCR-RFLP analysis and ...
The present study utilizes polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis using partial plastid rbcL and mitochondrial trnC-trnP gene sequences to distinguish the six representative Pyropia species produced via mariculture in Korea. The rbcL, trnC, and trnP sequences of 15 Pyropia species from the NCBI database were aligned to determine specific restricti...
In this study we attempted to modify the PCR-RFLP method using restriction enzyme MwoI for the identification of medically important Aspergillus species. Our subjects included nine standard Aspergillus species and 205 Aspergillus isolates of approved hospital acquired infections and hospital indoor sources. First of all, Aspergillus isolates were identified in the level of species by using morp...
We developed a novel PCR-restriction fragment length polymorphism test for the ccrB gene by using HinfI and BsmI for rapid typing of staphylococcal cassette chromosome mec (SCCmec). When tested with reference strains and methicillin-resistant Staphylococcus aureus isolates, the method proved to be valid and useful for rapid identification of four SCCmec types, especially type IV.
background and objectives: avian tuberculosis is one of the most important infections affecting most species of birds. mycobacterium avium can not only infect all species of birds, but also infect some domesticated mammals.the most crucial aspect of control and eradication scheme is identification of infection sources and transmission routs. mo- lecular techniques such as restriction fragment l...
