One hundred and sixty chickens (Gallus gallus) from 31 small, private backyard flocks in the eastern part of the Czech Republic were examined for chewing lice (Phthiraptera: Amblycera, Ischnocera). At least one species of chewing lice was found on every bird examined. Seven species of chewing lice were identified in all; they had the following prevalences and mean intensities: Goniocotes gallin...

Head lice infestation is associated with limited morbidity but causes a high level of anxiety among parents of school-aged children. Since the 2002 clinical report on head lice was published by the American Academy of Pediatrics, patterns of resistance to products available over-the-counter and by prescription have changed, and additional mechanical means of removing head lice have been explore...

This is a survey of 120 children for scabies and head lice infestations in a welfare home in Pulau Pinang. Children from this welfare home (Rumah Kanak-Kanak Taman Bakti, Kepala Batas, Pulau Pinang) were randomly selected. Majority of them were Malays (72.5%) and the rest were Indians. The infestation rates were highest in the 10-12 years age group with 46% and 70% for scabies and head lice res...

Phthiriasis palpebrarum, caused by the phthirus pubis, is a rare cause of blepharoconjunctivitis, and is therefore often neglected. We present 2 patients who suffered itching and irritation at the right upper eyelid. Biomicroscopic examination showed a few lice and nits anchored to the eyelashes. Dermatologic examination revealed the presence of numerous lice and nits at the trunk and pubic are...

results a total number of 20 out of 1772 (1.12%) examined students were found to be infested by lice. although the infestation rate was higher in girls, the difference of infestation rate between genders was not statistically significant (p > 0.05). the rate of head lice infestation was siginificantly (p < 0.05) correlated to their hair-washing behavior. parents’ literacy level also was siginif...

Background and aims: Pediculosis is one of the most common parasitic diseases that affect a wide range of age groups. The prevention of head lice infections promotes the physical and mental health of people in the community. Thus, the aim of this study was to investigate the prevalence of head lice infections and the factors affecting them in those who referred to health centers in Geras...

We compared patterns of mitochondrial DNA (mtDNA) differentiation in three host-specific lice (Halipeurus abnormis, Austromenopon echinatum and Saemundssonia peusi) and one generalist flea (Xenopsylla gratiosa), parasitizing 22 colonies of Cory's and Cape Verde shearwater (Calonectris). The shearwater hosts show distinct phylogeographic structure corresponding to the three taxa Calonectris d. d...

Developments towards a novel video camera based system for estimating the sea lice burden of freely swimming salmon are reported. The spectral reflectance of sea lice and salmon skin were measured over the wavelength range 400–1100 nm. Canonical variate analysis was then used to identify a combination of reflectances that maximises the differences between skin and sea lice. This is shown to pro...

Lice are obligate parasites of mammals and birds and have become an important model for studies of host-parasite co-evolution and co-phylogenetics. Population genetic and phylogeographic studies represent an important bridge between microevolution and co-phylogenetic patterns. We examine co-phylogeographic patterns in sika deer and their parasitic lice. Co-phylogeographic patterns in deer and l...
