A water snake (Natrix natrix) was referred to the Small Animal Teaching Hospital, Faculty of Veterinary Medicine, University of Tehran. It had two subcutaneous masses. Radiographic and ultrasonographic images revealed the presence of two subcutaneous abscesses. The abscesses were removed surgically and specimens were examined by conventional microbial culture and multiplex PCR. Inv-A universal ...

A rapid PCR-RFLP analysis was optimized to identify the presence of 3 closely related gadoid fish species: Alaska pollack Theragra chalcogramma, Pacific cod Gadus macrocephalus and Atlantic cod Gadus morhua in commercial seafood products. Gadoid universal primers were designed for PCR amplification of a 558-bp fragment encoding the mitochondrial cytochrome b gene. Without purification of the PC...

A nylon flocked swab/universal transport medium collection method developed for bacterial sexually transmitted infections was adapted to detect respiratory viruses in infants and toddlers. This method significantly outperformed the traditional use of nasal aspirates in terms of PCR-based virus detection (P = 0.016), and the samples were easier for clinicians to evaluate, store, and transport.

In the present study, we developed a quick, highly specific method for detection of Shigella species by combining immunocapturing of the bacteria and a universal primer PCR. The method drastically enhances test sensitivity, and it can be used not only for identification of Shigella species in the environment but also for rapid detection of other pathogens.

9 PCR amplification of pure bacterial DNA is vital to the study of bacterial interactions 10 with corals. Commonly used bacterial-specific primers 8F and 27F paired with universal 11 primer 1492R amplify both eukaryotic and prokaryotic rDNA. An alternative primer set, 12 63F/1542R, is suggested to resolve this problem. 13

PCR amplification of pure bacterial DNA is vital to the study of bacterial interactions with corals. Commonly used Bacteria-specific primers 8F and 27F paired with the universal primer 1492R amplify both eukaryotic and prokaryotic rRNA genes. An alternative primer set, 63F/1542R, is suggested to resolve this problem.

The use and validation of a strategy that allows a universal set of bar-coded sequencing primers to be appended to an amplified PCR product is described. The strategy allows a modular approach, in that the same bar code can be used with two or more target-specific primer sets, even simultaneously.

The Polymerase Chain Reaction (PCR) has facilitated the detection of unculturable microorganisms in virtually any environmental source and has thus been used extensively in the assessment of environmental microbial diversity. This technique relies on the assumption that the gene sequences present in the environment are complementary to the "universal" primers used in their amplification. The re...

PROBLEM To study the relationship between perinatal prognosis in cases of preterm labor (PTL) and polymicrobial infection in amniotic fluid (AF) and intra-amniotic (IA) inflammation using a highly sensitive and reliable PCR-based method. METHOD OF STUDY To detect prokaryotes using a nested PCR-based method, eukaryote-made thermostable DNA polymerase without bacterial DNA contamination was use...

Two sets of deprotection conditions have been evolved for the deprotection of oligodeoxyribonucleotides and their cleavage from commercially available cis -diol group-bearing universal polymer supports. In the first case, oligodeoxyribonucleotides anchored on the universal support were subjected to one of the standard deprotection conditions followed by treatment with aqueous 0.5 M sodium chlor...
