background: we evaluated the genetic diversity of samples identified morphologically as fasciola spp. from sheep, cattle and goat from kermanshah province, western iran using pcr-rflp method. methods: we used pcr-rflp analysis of ribosomal its1 fragment using rsai restriction enzyme to investigate the genetic characteristics of fasciola species obtained from different hosts (16 sheep, 28 cattle,...

conclusions this study provided conserved b-cell epitopes and peptides that can be useful for designing entry inhibitors and vaccines able to cover a global population, especially where genotype 5a is common. results differences in the probability of glycosylation in e1 and e2 regions were observed in this study. three conserved antigenic b-cell epitopes were predicted in the e2 regions and als...

patients and methods 720 cases including 120 patients undergoing hemodialysis, and 600 patients with hiv infection were studied. all cases with positive results for hbsag were evaluated for the presence of anti-hdv antibodies. samples with anti-hdv positive results were subjected to nested pcr for hdv-rna confirmation, and sequenced for hdv genotype determination. results hbsag was found in 9 (...

the effect of genotype and sex of nigerian indigenous chickens (dwarf, fulani ecotypes, neck, frizzle and normal feathered) on blood serum electrolytes and biochemical parameters were investigated using 40 chickens. the collected data were subjected to analysis via a 2 way anova. the results revealed serum levels of sodium, potassium, chloride, uric acid, glucose, total protein, creatinin, albu...

morphological, biochemical and molecular characteristics were studied to identify dominant lactic acid bacteria (lab), isolated from traditional yoghurts produced by tribes of iran. from 60 yoghurt samples, a total of 137 lab isolates were determined, in which 66 and 71 were identified as lactic acid cocci and bacilli, respectively. biochemical tests showed the occurrence of 9.76% mesophilic ho...

The avianuncoupling protein (avUCP) is a member of the mitochondrial transporter superfamily that uncouples proton entry in the mitochondrial matrix from ATP synthesis. The polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method was used to estimate the allele and genotype frequencies of the UCP/HhaI polymorphisms and to determine associations between these polymorp...
