In this study, Substitution at codon Ser315 of katG gene, a reliable marker for isoniazid (INH) resistance was analyzed and compared by three molecular methods such as DNA  sequencing, polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) and PCR-single strand conformation polymorphism (PCR-SSCP) in 105 phenotypically resistant isolates obtained from various parts of Ind...

Distinguishing herpes virus infection from other skin diseases is sometimes difficult. This study aims to detect herpes virus DNA by multiplex real-time PCR without nucleic acid extraction in a short period of time. Specimens of cutaneous vesicles and swabs were obtained from 23 patients suspected of having herpes virus infection. These specimens were stored at -80 degrees C after dissolving th...

Ninety-six plasma and whole blood specimens from nine selected patients were analyzed for the presence of Aspergillus DNA. Nineteen specimens from three patients with proven aspergillosis were PCR positive in both materials, whereas an additional 22 were PCR positive in whole blood only. All 36 samples from six patients without signs of aspergillosis were negative in both assays. We conclude th...

Mycoplasma hyopneumoniae is the primary agent of mycoplasmal pneumonia in swine. In this study we performed an arbitrarily primed PCR (AP-PCR) analysis, in which low-stringency amplification with a single primer was used, to investigate genetic variability in M. hyopneumoniae strains and field isolates. We performed preliminary experiments to examine the efficacy of 40 different 10-mer oligonuc...

In 2019, wilt and sudden death were observed on Artocarpus heterophyllus (jackfruit). Identification was performed by sequence analysis of the concatenated β-tubulin ITS gene regions. Sequencing PCR product confirmed this pathogen Ceratocystis fimbriata sensu stricto. This is first report C. causing disease in A. Indonesia worldwide.

BACKGROUND The current reference test for the detection of S. mansoni in endemic areas is stool microscopy based on one or more Kato-Katz stool smears. However, stool microscopy has several shortcomings that greatly affect the efficacy of current schistosomiasis control programs. A highly specific multiplex real-time polymerase chain reaction (PCR) targeting the Schistosoma internal transcriber...

The goal of this retrospective study was to evaluate the performance of different diagnostic tests for Legionnaires' disease in a clinical setting where Legionella pneumophila PCR had been introduced. Electronic medical records at the Cleveland Clinic were searched for Legionella urinary antigen (UAG), culture, and PCR tests ordered from March 2010 through December 2013. For cases where two or ...

  Among the viruses infecting honey bees, chronic bee paralysis virus (CBPV) is known to induce significant losses in honey bee colonies. CBPV is an unclassified polymorphic single stranded RNA virus. Using RT-PCR, the virus infections in honey bees can be detected in a rapid and accurate manner. Bee samples were collected from 23 provinces of Iran, between July-September 2011 and 2012. A tota...

The prevalence of some tick-borne zoonotic bacteria (Borrelia sp., Coxiella burnetii, and Rickettsia sp.) in dog blood samples were examined using by PCR. A total 200 collected from dogs located western Türkiye. Three pathogens for dogs, Borrelia burgdorferi, C. burnetii sp. detected samples. single PCR was performed the multiplex applied Rickettsiae spp. burgdorferi. At end study, target ident...

The reverse transcriptase-polymerase chain reaction (RT-PCR) has become widely used for monitoring minimal residual disease after allogeneic stem cell transplantation (SCT) for chronic myeloid leukemia (CML). However, most of these studies were performed using qualitative RT-PCR, and the interpretation of the results obtained has been conflicting. The correlation of a quantitative RT-PCR test p...
