  The aim of the present study is rapid detection of tuberculosis from pleural effusion of suspected patients. Molecular technique Nested Polymerase Chain Reaction (PCR) was used for the purpose. A total of 67 pleural fluid collected at Hospital University Kebangsaan Malaysia during May 2005 to October 2006 were sent to Microbiology Laboratory enrolled in the study. Detection rate of Mycobacterium tuberculosis in pleural effusion was 0% by acid-fast bacilli (AFB) staining and 1.5% by culture on Lowenstein-Jensen medium. Mycobacterium tuberculosis was detected by PCR in 9% of the cases. PCR of pleural fluid had 19% sensitivity and 96% specificity, compared to AFB staining (0% sensitivity and 100% specificity) and culture (4% sensitivity and 100% specificity). PCR also has 67% Positive Predictive Value (PPV) and 72% Negative Predictive Value (NPV) in detecting Mycobacterium tuberculosis. Culture of pleural fluid has 100% PPV and 71% NPV while AFB staining has 0% PPV and 31% NPV. This preliminary study showed that PCR is a rapid method for detection of Mycobacterium tuberculosis in pleural fluid but its sensitivity is not up the marked.

  A total number of 157 samples were examined by 4 different tests-In-house rapid urease (iRUT), Culture, Histopathology and Immunochromatography (Immuno CardSTAT) for the detection of Helicobacter pylori from the patients reported to Hospital Kuala Lumpur, Malaysia during 2007 to 2008. Out of the samples examined 47 (29.9%) were positive for H. pylori by the tests used in the laboratory. Efficacy of detection of the bacteria by the tests- In-house rapid urease, Culture, Histopathology and Immuno CardSTAT were 31.8, 13.9, 30.3 and 32.8%, respectively. However, sensitivity and specificity of the iRUT were 91.5 and 93.6%, respectively and the Positive Predictive Value (PPV) was 86% and the Negative Predictive Value (NPV) was 96.3%. The sensitivity for Immuno CardSTAT rapid test was 100% and the specificity was 79.3%. The PPV was 50% and the NPV was 100%. Convenient methods to the authors were ‘In house rapid urease test and Immunochromatography though variability of specificities were observed.

  Respiratory system is the primary settlement place of opportunistic organisms and considered as chief carrier of common respiratory pathogens. The aim of the study was to know the opportunistic organisms present in the healthy subjects as well as subjects that were suffering from respiratory symptoms. The organisms were identified as per standard bacteriological protocol and pathogenicity tests of the identified organisms were performed in mouse model. Antibiotic sensitivity of the identified organisms was performed. The bacterial flora present in the throat swab of apparently healthy as well as subjects suffering from respiratory symptoms were: Staphylococcus spp. (39.44%) of which Coagulase positive Staphylococcus (21.13%) and Coagulase negative Staphylococcus (18.31%), Klebsiella spp. (19.72%), Pseudomonas spp. (15.49%), Proteus spp. (4.23%), E. coli (9.86%) and Bacillus spp. (11.27%). Among the isolates Staphylococcus, Klebsiella and Pseudomonas were the predominant species. Percentages of identified bacteria were higher in respiratory symptoms exhibiting individuals (53.52%) than apparently healthy individuals (46.48%). All coagulase positive Staphylococcus, Klebsiella spp. and Pseudomonas spp. isolated from respiratory symptoms’ subjects were found to be pathogenic. The isolated bacteria were resistant to amoxicillin and ampicillin but sensitive to ciprofloxacin and norfloxacin. Isolated Pseudomonas spp. showed multidrugs resistant properties. The study provided information about the pathogenic organisms’ present respiratory systems of apparently healthy as well as subjects suffering from respiratory symptoms. The pathogenic natures of the isolated organisms were determined to make aware of scientists as well as clinicians. Antibiotics sensitivity assays would provide information to the clinicians for the selection of appropriate antibiotics to treat their patients.
