We constructed full-length cDNA clones of Sindbis virus that can be transcribed in vitro by SP6 RNA polymerase to produce infectious genome-length transcripts. Viruses produced from in vitro transcripts are identical to Sindbis virus and show strain-specific phenotypes reflecting the source of RNA used for cDNA synthesis. The cDNA clones were used to confirm the mapping of the causal mutation o...

A molecular epidemiological study of Mycobacterium simiae strains isolated from AIDS patients in Guadeloupe was performed by the random amplification of polymorphic DNA (RAPD) and pulsed-field gel electrophoresis (PFGE) of DraI- or XbaI-digested bacterial DNAs. A comparison of RAPD profiles suggested a similarity of banding patterns within a group of patients (two clusters of two and three pati...

OBJECTIVES This study aimed to investigate Salmonella Enteritidis strains isolated from human and food sources in the north of Morocco by means of phenotypic and genotypic methods. METHODOLOGY Fifteen isolates from humans and food were submitted to phage typing, XbaI-macrorestriction (pulsed field gel electrophoresis [PFGE]), enterobacterial repetitive intergenic consensus (ERIC-PCR), antimic...

The proteinase inhibitor null (Pi-) allele is a rare cause of alpha 1 antitrypsin (AAT) deficiency. In three families, all the subjects with AAT deficiency due to PiZ- presented in early childhood with recurrent chest infections and wheezing presumably related to passive smoking. In Pi- the AAT gene is present and there is no evidence for a gene deletion. In one family a restriction fragment le...

To determine the usefulness of MspI/int22h-1 (intron 22 homologous region-1) polymorphism of the factor VIII gene for molecular genetic diagnosis of hemophilia A in the Korean population, MspI/intron 22 and XbaI/intron 22 polymorphisms were analyzed in 101 unrelated Korean families with severe hemophilia A. The expected heterozygosity rates of MspI/int22h-1 and XbaI/int22h-1 polymorphisms ...

Mycobacterium chelonae and Mycobacterium terrae were reported to be frequently present in the environment of the Mycobacterium bovis BCG trial area in south India. Six isolates of M. chelonae and four isolates of M. terrae obtained from different sources in this area were analyzed by pulsed-field gel electrophoresis (PFGE) to examine large-restriction-fragment (LRF) polymorphism using the chrom...

the present study was aimed to construct a fusion plasmid harboring the extracellular domain of the influenza a m2-protein (m2e), which was fused to the n-terminus of the truncated hsp70 (hsp70359–610) molecule as a new approach for future vaccine research against influenza a. the amplified fragments, m2e and hsp70359-610 genes, were gel-purified. the products were then single digested with bam...
