An attempt has been made to analyze the distribution of the beta-lactoglobulin genotype in swamp buffaloes and Murrah buffaloes utilizing polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Blood samples were taken from 50 swamp buffaloes and 50 Murrah buffaloes. The DNA was extracted by the phenol-chloroform method. The PCR-RFLP was performed using beta-lactoglobulin ...
Introduction: The aim of the present study was to investigate the presence and the frequency of EAEC as etiologic agent of diarrhea in Shiraz. Enteroaggregative E. coli (EAEC) is increasingly recognized as a cause of often persistent diarrhoea in children and adults in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide. Materials and...
BACKGROUND Identification of the causative agents of invasive fungal infections (IFI) is critical for guiding antifungal therapy. Cultures remain negative in a substantial number of IFI cases. Accordingly, species identification from formalin fixed, paraffin embedded (FFPE) tissue specimens by molecular methods such as fluorescence in situ hybridisation (FISH) and PCR provides an appealing appr...
background: trichomoniasis is a worldwide protozoan parasitic disease and metronidazole is a choice drug for its treatment. because of disease importance in public health and its controversial ideas about the prevalence of drug resistance, this study was carried out. methods: fifty-two suspected vaginal samples were collected from 2006 to 2007 in gynecology maryam hospital, tehran, iran. all is...
background: dirofilaria immitis and dirofilaria repens are the most common species of filarial nematodes described in the dogs. a single-step multiplex pcr was applied to detect and differentiate simultaneously and unequivocally d. immitis and d. repens on dna extracted from canine peripheral blood and besides to detect the seroprevalance of d. immitis by elisa in elazig province, turkey. a pc...
bovine venereal campylobacteriosis, caused by campylobacter fetus subsp. venerealis (cfv), is regarded as one of the major threats to the cattle industry around the world. abortion and infertility are two important reproductive problems in cows infected with c. fetus subsp. venerealis. reports on the presence of cfv are scarce in the cattle, in iran. therefore, the present study was designed to...
بررسی مولکولی گونه های بیماریزای آسپرژیلوس جدا شده زخم پای افراد دیابتی با استفاده از روش Nested PCR
Background and Aim: PCR has high sensitivity and specificity for the determination offungal DNA. It is also useful for rapid identification of the most common species of Aspergillus. The purpose of this study was to compare culture method with nested PCR method to determine Aspergillesion in diabetic foot patient in Imam Khomeini Hospital, Tehran. Material and Methods: Sixty-five case...
BACKGROUND Molecular diagnosis using urine is established for many sexually transmitted diseases and is increasingly used to diagnose tumours and other infectious diseases. Storage of urine prior to analysis, whether due to home collection or bio-banking, is increasingly advocated yet no best practice has emerged. Here, we examined the stability of DNA in stored urine in two populations over 28...
