1. Gastrointestinal helminths in dog feces surrounding suburban areas of Lower Dir district, Pakistan: A public health threat
Resumo Dados sobre a contaminação ambiental dos parasitas de importância zoonótica são escassos no Paquistão. A contaminação do solo com fezes de cães, as quais escondem as fases infecciosas do parasita, representa um risco à saúde dos seres humanos. Este estudo teve como objetivo avaliar os ovos de parasitas gastrointestinais de cães de rua e do

2. Intestinal parasitic infections among expatriate workers in various occupations in Sharjah, United Arab Emirates
ABSTRACT Intestinal parasitic infections are prevalent throughout many countries. This study aimed to determine the prevalence of intestinal parasite carriers among 21,347 expatriate workers, including food handlers and housemaids attending the public health center laboratory in Sharjah, UAE. Stool sample collection was performed throughout the period betwee

3. HIGH PREVALENCE OF Blastocystis spp. INFECTION IN CHILDREN AND STAFF MEMBERS ATTENDING PUBLIC URBAN SCHOOLS IN SÃO PAULO STATE, BRAZIL
After a gastroenteritis outbreak of unknown etiology in the municipality of Sebastião da Grama, SãoPaulo, Brazil, we conducted a parasitological survey to establish the epidemiological profile of enteroparasitosis in children and staff members attending the public urban schools in operation in town. The cross-sectional study evaluated 172 children aged 11

4. Prevalence of intestinal parasites and risk factors forspecific and multiple helminth infections in a remote city of the Brazilian Amazon
Abstract: INTRODUCTION: Few studies have described the risk factors of intestinal parasitic infections in the Amazon. METHODS: A cross-sectional survey was performed in a City of the State of Amazonas (Brazil) to estimate the prevalence of intestinal parasites and determine the risk factors for helminth infections. RESULTS: Ascaris lumbricoides was the mo

5. Clinical conditions associated withintestinal strongyloidiasis in Rio de Janeiro, Brazil
INTRODUCTION: Strongyloides stercoralis is a soil-transmitted helminth that produces an infection that can persist for decades. The relationships between certain clinical conditions and strongyloidiasis remains controversial. This study aims to identify the clinical conditions associated with intestinal strongyloidiasis at a reference center for infectious

6. SEROPOSITIVITY FOR ASCARIOSIS AND TOXOCARIOSIS AND CYTOKINE EXPRESSION AMONG THE INDIGENOUS PEOPLE IN THE VENEZUELAN DELTA REGION
The present study aimed at measuring seropositivities for infection by Ascaris suum and Toxocara canis using the excretory/secretory (E/S) antigens from Ascaris suum (AES) and Toxocara canis (TES) within an indigenous population. In addition, quantification of cytokine expressions in peripheral blood cells was determined. A total of 50 Warao indigenous were

7. Lower production of IL-17A and increased susceptibility to Mycobacterium bovis in mice coinfected with Strongyloides venezuelensis
The presence of intestinal helminths can down-regulate the immune response required to control mycobacterial infection. BALB/c mice infected with Mycobacterium bovis following an infection with the intestinal helminth Strongyloides venezuelensis showed reduced interleukin-17A production by lung cells and increased bacterial burden. Also, small granulomas and

8. Diagnosis of Giardia infections by PCR-based methods in children of an endemic area
The present study was designed to estimate the prevalence of Giardia infection in preschool- and school-aged children living in an endemic area. Fecal samples from 573 children were processed by zinc sulfate centrifugal flotation, centrifugal sedimentation (using a commercial device for fecal concentration - TF-Test kit®) and polymerase chain reaction (PCR)

9. Helmintíase intestinal afeta negativamente a resposta celular específica contra o Mycobacterium tuberculosis em pacientes co-infectados
Mycobacterium tuberculosis (MTB) é um exemplo clássico de patógeno para o qual a resposta protetora depende da imunidade celular do tipo Th1, que é caracterizada pela presença de linfócitos T CD4+ produtores de IFN-g. Essa citocina ativa mecanismos microbicidas no macrófago infectado, levando à eliminação do bacilo. Evidências sugerem que a progre

10. Enteroparasitosis prevalence and parasitism influence in clinical outcomes of tuberculosis patients with or without HIV co-infection in a reference hospital in Rio de Janeiro (2000-2006)
Tuberculosis and intestinal parasites affect primarily low social and economic level populations, living clustered in precarious habitational settings. One of the interesting aspects of this interaction is the parasitism influence in cellular response to tuberculosis. In the present study, we evaluated the prevalence of enteroparasitosis in tuberculosis pati

11. Prevalence and pathology of the nematode Heterakis gallinarum, the trematode Paratanaisia bragai, and the protozoan Histomonas meleagridis in the turkey, Meleagris gallopavo
The prevalence of infection and associated pathology induced by two helminth and one protozoan species infecting Brazilian turkeys are reported. The intestinal nematode Heterakis gallinarum appeared with a prevalence of 70% in the infected birds, without gross lesions when not associated to the protozoan Histomonas meleagridis. Histological findings in the c

12. Estudo de prevalência e incidência de reação sorológica positiva para toxocara em crianças matriculadas na primeira série do ensino fundamental público no município de Vitória-ES
Background. High prevalence of anti-Toxocara antibodies has been reported in inpatients at one reference pediatric hospital in Vitoria, but there was not any report of this prevalence in healthy children. Objectives. (a)To study the prevalence and incidence of Toxocara infection by searching anti Toxocara antibodies in schoolchildren seven to nine years old;
