Toxocariasis is a widespread helminth infection of dogs and cats, caused by Toxocara canis cati larvae, respectively. spp. can cause zoonotic infections in humans invading tissues organs causing pathology. larvae release excretory-secretory molecules (TES) into the body their host that are fundamental to host-parasite interaction could be used as targets for novel diagnostics vaccines. In present study, we identified 646 T. proteins from TES larval extract using 1D-SDS PAGE followed mass...
Since the nematodes Trichuris trichiura and T. suis are morphologically indistinguishable, genetic analysis is required to assess epidemiological cross-over between people pigs. This study aimed clarify transmission biology of trichuriasis in Ecuador. Adult worms were collected during a parasitological survey 132 46 pigs Esmeraldas Province, Morphometric 49 pig 64 human revealed significant variation. In discriminant morphometric characteristics correctly classified male according host...
Background Environment may have a key role in the development of immune system childhood and environmental exposures associated with rural residence explain low prevalence allergic autoimmune diseases tropics. We investigated effects urban versus on adaptive response children living areas tropical region Latin America.Methods recruited school either communities Province Esmeraldas or neighborhoods city Esmeraldas, Ecuador. collected data by questionnaire intestinal parasites examination...
Background There are few prospective longitudinal studies of soil-transmitted helminth (STH) infections during early childhood. We studied the epidemiology and risk factors for from birth to 8 years age in tropical Ecuador. Methods 2,404 newborns were followed with periodic stool sample collections. Stool samples collected also household members at time child’s examined by microscopy. Data on social, environmental, demographic characteristics maternal questionnaire. Associations between...
Early-life exposures to geohelminths may protect against development of wheeze/asthma and atopy.To study the effect maternal infections in children during first 5 years on atopy, airways reactivity/inflammation at 8 years.Birth cohort 2404 neonates followed rural Ecuador. Data were collected by questionnaire atopy skin prick test (SPT) reactivity 9 allergens. We measured bronchodilator, fractional exhaled nitric oxide (FeNO) nasal eosinophilia. Stool samples examined for microscopy.1933...
In the present article, we provide shortly, data on risk factors for acquiring Toxocara spp. infection and investigate possible associations between this with atopy asthma in school children of a small town its semi-rural areas Northeast Brazil. The set are composed by demographic, social home environment variables. detection anti-Toxocara IgG specific IgE to aeroallergens was determined ELISA ImmunocAP/Phadiatrope systems, respectively. presented article related entitled "Risk...
Abstract The World Asthma Phenotypes (WASP) study is being conducted in five centres Brazil, Ecuador, Uganda, New Zealand and the United Kingdom, with a range of prevalence levels exposures, likely phenotype distributions. Here we present main findings regards to asthma inflammatory phenotypes. We recruited 998 cases 356 controls: 204/40 176/67 207/50 235/132 Zealand, Kingdom. All studied children adolescents (age-range 8–20 years), exception UK centre which involved 26–27 year olds....
Background: Early-life exposures to geohelminths may protect against the development of wheeze/asthma and atopy. Objective: Study effect maternal infections in children during first 5 years life on atopy, wheeze/asthma, airways reactivity/inflammation at 8 years. Methods: Birth cohort 2,404 neonates followed rural Ecuador. Data were collected by questionnaire atopy skin prick test (SPT) reactivity 9 allergens. We measured bronchodilator, fractional exhaled nitric oxide (FeNO), nasal...
