congenital toxoplasmosis is associated with variable complications including encephalitis, microcephaly, hydrocephaly, hepatitis, lymphadenopathy and even intrauterine death. presence of toxoplasma gondii in human placenta may induce congenital infection. the aim of this study was to determine the genotypes of toxoplasma gondii infection in human spontaneous aborted fetuses in shiraz, south of ...

conclusions the main and frequent hbv genotype among azerbaijani patients with chronic hepatitis b virus infection was genotype d followed by genotype a. results the mean age of patients was 35.9 ± 11.7 years (19-66). of 103 patients, 72 (69.9%) were male. in the present study, the predominant hbv genotype was d (93.2%) followed by genotype a (5.8%) and concurrent infection with a and d genotyp...

background: genetic polymorphisms of cytochrome p450 in humans are the main cause of differences in the metabolism. the allele and genotype frequencies of cyp2c19 and cyp2c9 have been studied in some iranian populations. the aim of present study was to examine the frequencies of cyp2c18m1, and cyp2c18m2, alleles in the mazandarani ethnic group among iranian population. materials and methods: in...

conclusions the majority of hiv-infected persons in the city of kashan were also hcv positive. genotype 1 was the predominant type, alongside subtype a. considering the high prevalence of hcv among the hiv-infected persons, as well as the impact of occupation, education, illicit drug use, and imprisonment on the incidence of both infections, health policy makers must introduce health programs a...

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...
