The aim of this study was molecular identification of S. aureus strains isolated from mastitic milk samples and establishing the genetic relationship between strains isolated from cows belonging to the same herd. In all 43 isolated strains the gap gene (930 bp) was amplified, which enabled their affiliation to the Staphylococcus genus to be established. PCR-RFLP with AluI endonuclease of the ga...

A DNA sequence typing scheme based on the caiC and SEN0629 loci was developed for differentiation of Salmonella Enteritidis strains and validated using a diverse collection of 102 isolates representing 38 phage types from different sources, year of isolation, geographical locations and epidemiological backgrounds. caiC encodes a probable crotonobetaine/carnitine-CoA ligase, and SEN0629 is a pse...

Discriminatory powers of various molecular techniques were evaluated for typing of methicillin-resistant Staphylococcus aureus (MRSA) isolated in Siriraj Hospital, Bangkok, Thailand. Thirty MRSA isolates were randomly selected in this study. They were characterized by pulsed-field gel electrophoresis, ClaI-mecA and ClaI-Tn554 polymorphisms, ribotyping, and PCR-based methods including SCCmec typ...

One hundred and ninety eight samples of human and animal sources from different areas in El-Sharkia Governorate were used in this study to isolate Staphylococcus species and to determine the presence of coagulase ( coa) gene,a virulence gene detected in S. aureus (CoPS), by PCR. Primary isolation on mannitol salt agar, $-haemolysis, tube coagulase test (TCT) and other biochemical characterizati...

background: optimal timing and mode of treatment for patients with coarctation of the aorta ( coa ) remain controversial, particularly in children. surgery, balloon dilatation, and stent implantation have all proven effective in the treatment of moderate or severe obstruction. the aim of this study was to investigate the complications of coa stenting angioplasty in pediatric patients. methods: ...

Staphylocoagulase detection is the hallmark of a Staphylococcus aureus infection. Ten different serotypes of staphylocoagulases have been reported to date. We determined the nucleotide sequences of seven staphylocoagulase genes (coa) and their surrounding regions to compare structures of all 10 staphylocoagulase serotypes, and we inferred their derivations. We found that all staphylocoagulases ...

Propionic acidemia (PA) and methylmalonic (MMA) are rare autosomal recessive disorders of propionyl-CoA (P-CoA) catabolism, caused by a deficiency in the enzymes P-CoA carboxylase methylmalonyl-CoA (M-CoA) mutase, respectively. PA MMA classified as intoxication-type inborn errors metabolism because intramitochondrial accumulation P-CoA, M-CoA, other metabolites results secondary inhibition mult...

the last two decades have seen a massive growth in the application of dna technology in histocompatibility and immunogenetics. this review summarises the history and application of dna methods in this area.

conclusions as about 70% of methicillin-resistant isolates belonged to sccmec iii, the present study can conclude that, over an 8-year period, only one dominant and stable clone of mrsa strain was found in tabriz hospitals. this finding could be a result of incorrect medical orientations, inadequate infection controlling policies, and insufficient preventive approaches. objectives the current s...

Background Aortic Coarcatation (CoA) is one of the congenital heart diseases with the rate of 5-8% of Coronary heart diseases(CHDs). Balloon angioplasty is now one of the effective way of treatment for CoA, native or Re-coarctation (Re-CoA). We aimed to assess the immediate, and short term response to angioplasty and stenting, and also complications. Materials and Methods Balloon angioplasty wi...
