Background: Head louse (Pediculus humanus capitis) is one of the common health problems of the children in elementary schools. The aim of this study was to determine risk factors associated with head lice (Pediculosis) infestation among elementary school students in Meshkinshahr County,  Northwestern Iran. Materials and Methods: This descriptive-analytic study is done over 1,950 students (1,055...

head louse infestation is common in various parts of the world. baluchestan area in southeast of iran is one of the most infected areas. we studied the head louse infestation among the girls in primary schools of iranshahr, which is the largest city of the province during november 2002 to may 2003. totally 918 pupils, between 6-14 years old from 12 urban primary schools were randomly selected b...

The aim of this study in Curaça, Bahia, Northeast Brazil was to explore possible factors associated with the infestation of human dwellings by Triatoma brasiliensis or Triatoma pseudomaculata, two sylvatic triatomine species. We use multiple logistic regression analysis to show how structural features of the peridomiciliary area combine with the number of animals and sociological factors to all...

BACKGROUND Fifty years of residual insecticide spraying to control Triatoma infestans in the Gran Chaco region of northern Argentina, Paraguay and Bolivia shows that vertically coordinated interventions aiming at full coverage have limited effects and are unsustainable. We quantified the spatial distribution of T. infestans domestic infestation at the district level, identified environmental fa...

A study to mea~ure the effect of walnut scale infestation on English walnut qualityand yield has shown no differences in yield and no consistentdifferencein kernel quality between infested and non-infested trees for the four years ~f the study. Yield and quality of English walnut are not overly sensitive to walnut scale infestation and some degree of infestation can be tolerated with no measura...

The prevalence of intestinal parasitic infestation and anaemic status of adolescent boys (age 10-19 years) of two selected villages, Kutumbopur, Comilla and Gazirchat, Dhaka districts was investigated. Anaemic status was determined by measuring hemoglobin percentage and parasitic infestation was detected and identified under microscope with wet mount and stained preparations. Out of 106 adolesc...

BACKGROUND Diagnosis of Armillifer armillatus infestation is usually incidental, commonly via autopsy or radiography. Affected individual are usually asymptomatic. The case presented here, however, had severe thoracic and abdominal involvement with clinical manifestations. AIM To report a case of heavy A. armillatus infestation in an adult female Nigerian rural dweller complicated by hepatic ...

Ecological aspects related to parasitism are one of the less studied issues in parasitology research, and the scarce evidence available supports that younger specimens present higher infestation rates. The purpose of this work is to establish if higher infestation rates are observed in nursing females and their young captured inside their roost. Bats were captured inside a shelter located in RP...
