Detection of Mycobacterium avium subsp. paratuberculosis in Cow Milk Using Culture and PCR methods

Mycobacterium avium subspecies paratuberculosis (MAP) is the cause of John’s disease also called paratuberculosis. This is economically one of the important infectious diseases in cattle and ruminant husbandry. This disease is manifested as granulomatosis entrocolitis, lymphadenitis and inflammation local lymphatic vessels. The typical sign of this disease is progressive loss of weight. Cons...

Evaluation of culture and PCR-based assay for detection of Mycobacterium tuberculosis from sputum collected and stored on filter paper.

We evaluated the use of culture and PCR-based assay for the direct detection of Mycobacterium tuberculosis (MTB) from sputum collected and stored on filter paper at room temperature for 5 days; the results were compared with those of staining and conventional culture of fresh sputum before storage (the 'gold standard'). Out of 231 sputum specimens examined, MTB was recovered from 124 samples by...

Evaluation of a novel PCR-based diagnostic assay for detection of Mycobacterium tuberculosis in sputum samples.

We report on a PCR-based assay we have developed for the detection of Mycobacterium tuberculosis in sputum samples. One hundred sputum specimens, which included 34 culture-positive and 66 culture-negative specimens, were evaluated with this system. Of the 34 culture-positive specimens, 31 were PCR positive, and 60 of the culture-negative specimens were PCR negative. An internal standard has bee...

THE DETECTION OF Mycobacterium tuberculosis BY PCR IN SPUTUM SAMPLES FROM LONG-TERMTREATED LEPROSY PATIENTS: ASSOCIATIONS WITH SKIN TEST RESULTS AND IMMUNOTHERAPY WITH Mycobacterium vaccae

As part of a series of investigations at Baba Baghi Leprosarium in lran, 44 long-treated leprosy patients were selected for our study. Samples of early morning sputum were obtained from each patient, examined by microscopy for acid-fast bacilli (AFB), and cultured for tubercle bacilli. These tests were negative, but the polymerase chain reaction (PCR) for an insertion sequence believed to b...

Comparison of sensitivity and specificity of PCR and sputum smear compared to culture in diagnosis of tuberculosis

Background: Molecular detection has recently been proposed by nucleic acid amplification, known as polymerase chain reaction (PCR). The aim of this study was to compare the diagnostic method of smear and polymerase chain reaction with culture in terms of sensitivity, specificity, positive and negative predictive value in the diagnosis of pulmonary tuberculosis. Methods: In this cross-sectional...
