The Toxicity of Essential Oils From Three Origanum Species Against Head Louse, Pediculus humanus capitis.

Purpose: Pediculosis caused by human head louse, Pediculus humanus capitis De Geer (Anoplura: Pediculidae) is a public health problem with a high prevalence, especially among children in school age. Different chemical pediculicides (insecticides) are used against lice but the repeated application of these pediculicides for the treatment of P. humanus capitis infestation in the past decades has resulted in the development of resistance.

Entomological Survey for the Detection of Sand Fly Fauna and Vector Species in the Cutaneous Leishmaniasis Endemic Area in East Mediterranean Region of Turkey, Mersin Province.

Cutaneous (CL) and visceral (VL) forms of leishmaniasis, transmitted by sand flies, are seen in all countries located in Mediterranean Basin including Turkey. In this study, we aimed to conduct an entomological survey for the detection of sand fly fauna and vector species in Mersin province, one of the important endemic areas for CL in Turkey. In total, 912 sand fly specimens were collected in 2010 and 2011 using CDC light traps.

Detection of permethrin resistance and phylogenetic clustering of turkish head lice (Pediculus humanus capitis; De Geer, 1767 populations.

Head lice infestation caused by Pediculus humanus capitis De Geer, 1767 is one of the most common public health problems. The relationship between humans and head lice dates back millions of years ago that differentiated into different phylogenetic clades. Treatment of head lice infestation usually based on insecticide-based products, which promotes the resistance in the head lice populations.

Investigation of Intestinal Parasites in Living Nursing Home.

Objective: Intestinal infections are common in the elderly, presented with atypical symptoms and may be the cause of mortality with a more severe clinical manifestation. The weakening of cellular and humoral immunity by aging affects the intestinal flora and increases the risk of infection in the presence of chronic diseases. The aim of this study was to investigate the presence of possible parasitic agents in the intestinal system of ≥65-year-old nursing home residents through fecal examination, and to determine the demographic features (age and gender) of this elderly group.

In vitro Investigation of the Pediculicidal Activities of the Volatile Oil Components of Some Medical Plants Raised in Turkey.

Objective: The human head louse Pediculus capitis has recently acquired resistance to commercially available insecticides, which has expanded the search concerning the pediculicidal activities of some herbal products. The present study aimed to assess the in vitro pediculicidal activities of volatile oils extracted from 10 medical plants raised in Turkey: Rosa damascena (red provins rose), Pelargonium graveolens (geranium), Lavandula angustifolia (lavender), Salvia triloba (salvia), Rosmarinus officinalis (rosemary; two different chemotypes), Citrus bergamia (citrus tree), Cymbopogon nardus (citronella), Citrus limonum (lemon), and Cymbopogon flexuosus (lemongrass).

Methods: Head lice obtained from school children in Manisa Province were initially grouped as adults and nymphs and were then kept under optimal conditions (temperature of 27°C and humidity of 50%).
