RAPID DETECTION OF MYCOBACTERIUM TUBERCULOSIS IN CLINICAL SPECIMENS BY POLYMERASE CHAIN REACTION
We investigated the use of DNA amplification by polymerase chain reaction (peR) for detection of Mycobacterium tuberculosis in 300 patients who were suspected of having pulmonary tuberculosis and compared the results with culture results which were performed in parallel with PCR. Two-thirds of each sample was processed for smear and culture by standard methods and one-third was prepared fo...
متن کاملSpecific and Rapid Detection of Mycobacterium tuberculosis Complex in Clinical Samples by Polymerase Chain Reaction
Background. Tuberculosis, a global health problem and highly prevalent in India, has always been a serious problem with respect to definitive diagnosis. Polymerase chain reaction (PCR) techniques are now widely used for early detection and species differentiation of mycobacteria, but mostly with their own limitations. We aim to detect and differentiate Mycobacterium tuberculosis (Mtb) infection...
متن کاملPolymerase Chain Reaction Detection of Mycobacterium Tuberculosis from Sputum
Tuberculosis has remained to be a major public health problem in Nepal. The risk of spread of infection and emergence of drug-resistant strain has created the need for a rapid, sensitive and specific diagnostic test. In addition, clinically suspicious cases that do not give positive result in conventional laboratory test need more sensitive test for diagnosis. In order to evaluate the possibili...
متن کاملPolymerase chain reaction for detection of Mycobacterium tuberculosis.
A polymerase chain reaction for the specific detection of mycobacteria belonging to the Mycobacterium tuberculosis complex was developed. Using a single primer pair derived from the nucleotide sequence of protein antigen b of M. tuberculosis, we achieved specific amplification of a 419-base-pair DNA fragment in M. tuberculosis and M. bovis. After DNA was extracted from mycobacteria by using a s...
متن کاملSPECIFIC AMPLIFICATION OF ASPERGILLUS FUMlGATUS DNA BY POLYMERASE CHAIN REACTION
Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...
