mycoplasma synoviae (m. synoviae) is a major worldwide poultry pathogen that causes serious economic losses in the poultry industry. this study was designed to detect m. synoviae through culture isolation and polymerase chain reaction (pcr) assay to demonstrated the involvement of m. synoviae infection in trachea and the lung/air sac samples taken from commercial broiler chicken farms in 3 m...
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
Background: Early diagnosis of bacteremia and its complications is the most important part of care and management of the patients. The utility of polymerase chain reaction (PCR) techniques have been shown to identify pathogens in less and more optimal time. The aim of our study was to evaluate prevalence of bacteremia using universal PCR in febrile patients admitted in Pediatric Medical Center ...
background: chlamydia trachomatis is the most reported bacterial sexually transmitted disease, especially among young women worldwide. aim of this study was comparison to evaluate the prevalence of chlamydia trachomatis infection in woman with tubal infertility by means of pcr and cell culture techniques. methods: fifty-one women with confirmed tfi were enrolled in this study in (avicenna infer...
mycoplasma synoviae (ms) is an important avian pathogen that can cause both respiratory disease and joint inflammation synovitis in poultry, inducing economic losses to the iranian chicken industry especially breeder farms. the aim of this study was to use the ms specific pcr and culture methods in order to detect of m. synoviae from breeder farms where located in tehran province. a total of 47...
Contagious agalactia is an infectious syndrome of sheep that is characterized by mastitis with reduction of milk production, arthritis, abortion, and keratoconjunctivitis. The disease is rapidly spread by the contact of the infected animals with the healthy ones. Domestic sheep and goats of both sexes can be infected at an equivalent frequency. Most of the researchers use culture and molecular ...
Background: Bloodstream infections (BSI) have a high incidence and high mortality in the worldwide. The mortality rate is variable between 20-70%. Therefore, early and timely detection of BSI agent in clinical laboratories is necessary. The aim of this study was to determine an efficient diagnostic tool to septicemia in accompany of blood culture method by Real-time PCR (using panbacterial 23S ...
background :polymerase chain reaction (pcr) assay has widely used for the detection of tuberculosis (tb). this study tried to compare in-house pcr with some well-known commercial pcr kits for detection of tb agent. methods : clinical samples obtained from 620 tb suspected patients were analyzed for the diagnosis of mycobacterium tuberculosis complex (mtc) by in-house pcr. all samples were obtai...
background: ureaplasma urealyticum is known as a sexually transmitted agent, causing mainly urethritis, pelvic int1ammatory disease, spontaneous abortion, pyelonephritis, infertility, stillbirth, low birth weight neonatal meningititis, and neonatal pneumonia. u. urealyticum infections not only jeopardize fertility but also pose a risk for infertility treatment and resulting pregnancies. diagnos...
BACKGROUND Bacterial culture and polymerase chain reaction (PCR) assays for the detection of Streptococcus equi in nasopharyngeal washes (NPW) and guttural pouch lavage (GPL) samples have low sensitivity. In human diagnostics, processing of samples with flocked swabs has improved recovery rates of bacterial agents because of improved surface area and elution factors. HYPOTHESIS For S. equi su...
