Mycoplasma gallisepticum is the most important and infectious Mycoplasmosis. It is caused lots of economic losses for poultry's industry of Iran. The target of this study is comparison of culture and nested PCR techniques to detect Mycoplasma gallisepticum infection of chicken’s from industrial farms in Kerman province of Iran. 88 isolates received from industrial far...

The objective of this study is to investigate and compare the sensitivity in conventional PCR, quantitative real time PCR, nested PCR and western blots for detection of prostate cancer tumor markers using prostate cancer (PCa) cells. We performed conventional PCR, quantitative real time PCR, nested PCR, and western blots using 5 kinds of PCa cells. Prostate specific antigen (PSA), prostate spec...

background: anaplasmosis belongs to the complex of several tick-borne diseases and can cause diseases in the livestock with high economical losses. cattle that recover from acute infection become carriers and the parasite can persist most probably for the lifetime in the blood. the aim of the present study was the determination of the persistently infected cattle in a region of iran with the pr...

background and aims: canine distemper (cd) is a deadly infectious disease of canidae family. cd is a multi-systemic viral disease and is specified by wide range of clinical symptoms. the manifestations are not always indicative of cd, therefore a laboratory confirmation is necessary for suspected cases. materials and methods: different clinical specimens of 19 cd suspected unvaccinated dogs wer...

trematodes are important in economic and public health. ornithobilharzia turkestanicum (o. turkestanicum) is one of the important economic trematodes in domestic animals. ornithobilharzia infection in intermediate host (lymnaea gedrosiana ) can be detected by either exposing snails to light to induce cercarial shedding or by squeezing them between glass slides to detect parasites. the current a...

background: diagnosis of some diseases is difficult due to invasive sampling. urine has been candi-date as a non-invasive and convenient alternative. it has many advantages and easy accessibility but some technical ills should be removed. finding a suitable extraction method for improving urine dna quantity and quality in altering invasive specimens for molecular diagnosis of some infectious di...

Sensitivity and specificity are important for tests used to defect Helicobacter pylori infection from gastric biopsy specimens. Molecular methods, such as PCR and nested PCR, are sensitive methods for H. pylori detection. The objective of this study was to evaluate the performance of PCR and nested PCR compared to culture, the rapid urease test (RUT) and histology for the diagnosis of H. pylori...

background: hepatitis g virus (gbv-c) is a single strand rnapositive virus and is a member of flaviviridae family. infection with the virus is prevalent add has worldwide distribution. accurate diagnosis of the virus is very important, because of co-infection with other important viruses like hcv, hbv and hiv, it may influence on pathogenesis, disease progression and response to viral therapy. ...

This study was performed to evaluate nested polymerase chain reaction (PCR) and real-time PCR methods for detection of Strongyloides stercoralis in fecal samples compared with parasitological methods. A total of 466 stool samples were examined by conventional parasitological methods (formalin ether concentration [FEC] and agar plate culture [APC]). DNA was extracted using an in-house method, an...
