Identification of Cutaneous Leishmaniasis in Humans Through Polymerase Chain Reaction (PCR)

Polymerase Chain Reaction (PCR)

The polymerase chain reaction (PCR) is a powerful and widely used technique that has greatly advanced our ability to analyze genes. Genomic deoxyribonucleic acid (DNA) present in cells contains many thousands of genes. This makes it difficult to isolate and analyze any individual gene. PCR allows specific DNA sequences, usually corresponding to genes or parts of genes, to be copied from genomic...

Comparison of polymerase chain reaction with other laboratory methods for the diagnosis of American cutaneous leishmaniasis: diagnosis of cutaneous leishmaniasis by polymerase chain reaction.

An evaluation of 5 laboratory methods for diagnosing American cutaneous leishmaniasis (ACL) was carried out on patients from an endemic area of Brazil. From 164 patients presenting cutaneous lesions, and suspected to have ACL, 133 (81.1%) were confirmed for the disease by Montenegro skin test (MST) and/or parasitologic examination (PE). In both groups of patients, the positivity of polymerase c...

Identification of Meat Species by Polymerase Chain Reaction ( PCR ) Technique

The origin of horse, dog, cat, bovine, sheep, porcine, and goat meat was determined by the polymerase chain reaction (PCR) technique, using species-specific primers. Test mixtures of meat were prepared by adding 5%, 2.5%, 1%, 0.5%, and 0.1% levels of pork, horse, cat, or dog meat to beef, sheep, and goat meat. Samples taken from those combinations were analyzed by PCR for species determination....

Detection of Leishmania DNA in paraffin embedded specimens of chronic lupoid leishmaniasis using polymerase chain reaction

Background: Chronic lupoid leishmaniasis (CLL) is a chronicform of cutaneous leishmaniasis that is usually resistant to antileishmania agents and leishmania is not seen in the histologicsections. We used polymerase chain reaction (PCR) to detectleishmania DNA in CLL specimens.Method: This descriptive cross sectional study was done on20 paraffin embedded specimens of CLL cases referred to theder...
