nosema is a genus of microsporidia, which have significant negative impacts on honeybees. the aim of this study is the epidemiological evaluation and molecular characterization of nosema spices in various counties of east-azerbaijan province (northwest of iran). 387 samples were collected from colonies maintained in various counties of east-azerbaijan province. samples after preparation were...

conclusions the most frequent subtypes of hcv in iran were 1a, 3a and 1b, respectively. this frequency differed in various provinces of iran and fluctuated with time. it is important to determine the distribution of hcv genotypes in different geographical areas and its trend with time for epidemiological and patients’ management purposes. objectives the aim of this study was to estimate the ove...

results the highest prevalent genotype was genotype 4a, which was found in 57 patients (92%) followed by 2 isolates (3%) with genotype 4o, 2 strains (3%) with genotype 1g and one isolate (2%) with genotype 4n. conclusions this molecular epidemiology study revealed high prevalence of hcv genotype 4, subtype 4a among egyptian patients residing in sharkia governorate, egypt. patients and methods t...

background: group b streptococcus (gbs) is the major cause of serious life threatening infections in neonates, pregnant women, and other adults with underlying diseases. capsular polysaccharide typing is a significant way for epidemiological studies of gbs, the pathogenesis, and other studies associated with gbs infections including surveillance programs and vaccine development in future. molec...

conclusions molecular epidemiology studies of infectious diseases have been useful when bacterial isolates have been clustered in a period of time and in different geographical regions with variable antibiotic resistance patterns. in spite of high geographical differences and different antibiotic resistant patterns, low genetic diversity among the studied tb isolates may refer to the low rate o...

background and objectives: molecular typing methods are important and useful tools to assess the transmission, diversity of strains and differentiation between new infections and relapses which can effectively help in controlling infections. the aim of this study was to evaluate the molecular typing methods which have been used in iran. by evaluating the results and discriminatory power of each...
