Prevalence of Ectoparasitic Infections and Other Dermatological Infections and Their Associated Factors among School Children in Gampaha District, Sri Lanka

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2019, Issue 1, 2019., 2019
Skin disorders are one of the commonest conditions among school children in developing countries. There are only a few published studies available from Sri Lanka on the prevalence of skin disorders. A community‐based cross‐sectional study was carried out among five government‐run schools randomly selected from the district of Gampaha, Sri Lanka, during

Effectiveness of 10% NaOH Fixation with Variations in Heating Temperature on The Quality of Preserved Preparations Pediculus humanus capitis

Journal of Parasite Science
Preserved preparations are sample preparations that are useful for looking at the morphology of ectoparasites, one of which is head lice (Pediculus humanus capitis).

Pediculosis palpebrarum initially diagnosed as blepharitis

African Vision and Eye Health, 2009
Pediculosis is an infestation of lice. Eyelid involvement is uncommon, but can be caused by pediculus humanus capitis (head louse), rarely by  pediculus humanus corporis (body louse) and commonly by phthirus pubis (pubic louse).

Analyzing Bacterial Communities in Pediculus humanus capitis

The FASEB Journal, 2015
Understanding the composition of the microbiome of human associated insects can shed light on the sources of potential human pathogens. The human head louse, Pediculus humanus capitis, is an obligate symbiont found in the hair of humans, especially children. It is known to harbor an obligate endosymbiont, Candidatus Reisia.

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

Advanced Theory and Simulations, Volume 8, Issue 10, October 2025.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

Pediculus humanus capitis (head lice) and Pediculus humanus humanus (body lice): response to laboratory temperature and humidity and susceptibility to monoterpenoids

Parasitology Research, 2009
Human pediculosis is produced by Pediculus humanus humanus (Linnaeus 1758) and Pediculus humanus capitis (De Geer 1767). Laboratory-reared body lice, susceptible to insecticides, were used as reference in toxicological studies on head lice. In this work, we evaluated the survival of both subspecies at different temperatures and relative humidities and ...

Neandertal Cold Adaptation: Technological, Anatomical, and Physiological Responses to Cold Stress in One of Our Closest Fossil Relatives

American Journal of Human Biology, Volume 37, Issue 10, October 2025.
ABSTRACT Neandertals occupied western Eurasia for over 100 000 years, repeatedly enduring climates that ranged from seasonally cold to glacial. This paper reexamines the question of Neandertal cold adaptation using updated fossil, physiological, and archaeological evidence.

In Vitro Evaluation of Essential Oils Derived from Piper nigrum (Piperaceae) and Citrus limonum (Rutaceae) against the Tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)

Biochemistry Research International, Volume 2017, Issue 1, 2017., 2017
The present research aimed to study the chemical composition and acaricidal activity of Citrus limonum and Piper nigrum essential oils against the cattle tick Rhipicephalus microplus. GC‐MS analysis of C. limonum essential oil showed limonene (50.3%), β‐pinene (14.4%), and γ‐terpinene (11.7%) as the major components; P.
