purpose: to determine the prevalence and genotype of acanthamoeba keratitis (ak) in patients referred to farabi referral eye center methods: in this study, corneal scraping specimens that obtained from keratitis patients examined for acanthamoeba and its genotype identifications. direct smears, cultivation in non-nutrient agar (nna) followed by pcr were chosen as the basic diagnostic methods. t...

data collected in 2012 on 400 chickens were subjected to two-way analyses of variance to estimatebody weight, morphometric traits as well as the correlationbetween body weight and morphometric traitsin isa brown and ilorin ecotypechickens. the studied morphometric traits were comb length, beak length,head length, neck length, body length, wing length, shank length, thigh length, toe length, bre...

objective: microsporidia are ubiquitous opportunistic pathogens infecting all animal phyla. the purpose of this study was to characterization human-associated microsporidia in pigeons of tehran by staining and molecular methods. materials and methods: in the year 2010 a total of 147 pigeon’s fecal samples were randomly collected from bird stores and public parks of tehran and screened for the ...

background: cytochrome p450 2c19 (cyp2c19) is a polymorphically expressed enzyme that shows marked interindividual and interethnic variation. cyp2c19*2 and cyp2c19*3 are the most frequently identified defective alleles in orientals and caucasian poor metabolizers (pm). the aim of this study was to investigate the frequencies of cyp2c19*1, cyp2c19*2 and cyp2c19*3 alleles and cyp2c19 genotypes in...

background and objectives: human bocavirus (hbov) is a newly discovered parvovirus. it has been detected primarily in children with acute respiratory tract infections. this study was conducted to clarify the frequency and genotype circulation pattern of hbov in iran. materials and methods: conventional pcr was performed on throat swabs of patients less than two years of age with respiratory ill...

a polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) test was performed to investigate the allele frequencies of the insulin-like growth factor (igf1 and igf2 genes) in 90 broilerchickens. a 793 bp fragment of igf1 gene and 1146 bp fragment of igf2 gene were amplified and digested with hinfi and hsp92ii restriction enzymes,respectively. two types of alleles of a and b...

hereditary spastic paraplegias are highly heterogeneous neurodegenerative disorders with some special mutations. we report on a patient with pescavus, distal a myotrophy, hyper extended fingers, and pectus excavatum. neurological examination showed that he had proximal lower limbs weakness with a positive gower sign, exaggerated lower limbs deep tendon reflexes with spasticity, distal muscle wa...

cryptosporidium is one of the most common causes of childhood diarrhea in developing countries. the aim of this randomized pilot study was to detect and characterize infective species and determine the genotypes of cryptosporidium parasites in pediatric patients suffering from diarrhea in north west of iran. a total of 113 fecal samples were collected from diarrheic children hospitalized in tab...
