New primer-enzyme combinations for terminal restriction fragment length polymorphism (T-RFLP) targeting of the 16S rRNA gene were constructed by using the T-RFLP analysis program (designated TAP T-RFLP) located at the Ribosomal Database Project website, and their performance was examined empirically. By using the fluorescently labeled 516f primer (Escherichia coli positions 516 to 532) and 1510...

OBJECTIVES The utilization of molecular techniques in the epidemiology of tuberculosis have provided an opportunity for using effective markers to trace the transmission of the disease. The purpose of this study was to compare the genetic patterns of Mycobacterium tuberculosis by three methods of RFLP technique. MATERIALS AND METHODS In a cross-sectional and prospective study, 95 strains of M...

We report four disseminated cutaneous leishmaniasis(DCL) cases referred to leishmaniasis laboratory at the School of Public Health, Tehran University of Medical Sciences with multiple nodular, ulcerative and crusted lesions extended on the face, trunk, and extremities. None of the patients had any complication and historical involvement in their immunological system conditions that suggest as t...

Cutaneous leishmaniasis (CL) is an endemic disease and a public health problem in Hama governorate located in the central region of Syria. The aim of this study was to characterize Leishmania species isolated from human skin samples. A polymerase chain reaction, restriction fragment length polymorphism (PCR-RFLP) assay, was performed on skin lesion material samples from 32 patients with confirm...

Assessing microbiological quality assurance by monitoring bacteria in various sources of freshwater used for human consumption, recreation, and food preparation is important for a healthy life. Bacterial number and their community structure in freshwater should be determined as quickly as possible, and "real-time" and "on-site" microbiological methods are required. In this study, we examined th...

PPARGC1A is involved in many metabolic processes including normal mitochondrial biogenesis, oxidation of glucose and lipids transport into skeletal muscles. Previous researches linked this polymorphism with the higher risk developing type 2 diabetes, syndrome obesity. The aim study was to investigate association Gly482Ser body mass index (BMI), fasting levels lipid profile Serbian adolescents. ...
