background: dna extraction is one the most important steps for molecular analysis of food-borne pathogens. in this research, three methods of dna extractions from beef harboring sarcocystis spp. were compared for the quality, quantity, safety, as well as cost-effectiveness. methods: about 100 mg intersostal and diaphragm were collected from 10 slaughtered cattle. after ensuring their contaminat...

conclusions this study showed m. globosa to be the most common malassezia species isolated from malassezia skin disorders in kashan, iran. the pcr-rflp method was useful in the rapid identification of the malassezia species. by using these methods, the detection and identification of individual malassezia species from clinical samples was substantially easier. patients and methods a total of 14...

the rapidly expanding fields of pharmacogenomics and pharmacodiagnostics have presented the pathology laboratories with many challenges and opportunities. as custodians of patient tissues, these laboratories are in the logical position to perform biomolecular testing for proper management of patients. in order to meet these challenges, the pathology laboratories of the twenty-first century shou...

currently, different highly sensitive nucleic acid detection-based protocols used in medical diagnostic laboratories need specific working conditions, and if no optimization is performed, misleading results can be obtained. limitations of each protocol is different in obtaining an appropriate result. awareness of these limitations plays an important role in providing a reliable result for physi...

background: leishmaniasis represents a major public health concern in tropical and sub-tropical countries. at present, there is no efficacious vaccine against the disease and new control methods are needed. one way to access this important goal is to knock out genes of specific macromolecules to evaluate the effect of deletion on the growth, multiplication, pathogenesis and immunity of the para...

sarcocystis is one of the most prevalent parasites of domestic ruminants worldwide. this study was aimed to determine prevalence of sarcocystis infection and molecular discrimination of sarcocystis gigantea and sarcocystis medusiformis infecting domestic sheep. tissue samples from 638 sheep slaughtered at urmia abattoir were randomly collected from february 2011 to january 2012. genomic dna ext...

filariasis in dogs is caused by several species of filariids. because of importance of this infection in veterinary medicine and public health, it is necessary to carry out an epidemiological and cross sectional studies in various geographical areas and use of well-adapted diagnosis methods. in this study 205 capillary and whole blood samples were collected from doges in various counties of eas...

celiac disease (cd) is an immune-mediated disorder resulting in nutrient malabsorption now thought to have a prevalence of 1:100 in the iranian population.symptoms of cd are included diarrhea, abdominal pain, steatorrhea, bloating, cramps, flatulence, weight loss, weakness and short stature. in addition to presenting symptoms, patients are also at increased risk of metabolic bone disease, lymph...

phage elisa is a common method to confirm binding of obtained phages from phage display technique to related antigens. enzyme-conjugated antibody directed against the major capsid protein (pviii) or enzyme-conjugated secondary antibody against the primary antibody is used as a detection system in phage elisa. we have suggested to express an acid phosphatase (sapm) enzyme on m13 pix minor coat p...
