Objective: To determine if, in patients with head lice, spinosad cream rinse is more effective than permethrin. Design: Two identical, multicenter, randomized, evaluator/investigator-blinded, active-controlled trials. Setting: Twelve clinical research centers from the United States. Patients: People older than 6 months with live lice infestation as assessed by an evaluator. Intervention: Cluste...

Phthiriasis palpebrarum (PP) is a rare eyelid infestation caused by phthirus pubis. We report a case of PP mimicking lid eczema and blepharitis. A 68-year-old woman had moderate itching in both eyes. Her initial diagnosis was considered to be lid eczema or blepharitis because of findings similar to exfoliative lesions and color changes in eyelids and to excretions over eyelashes. Careful observ...

OBJECTIVE The present study was performed to record the mean monthly prevalence, intensity of infestation, sample mean abundance and frequency distribution pattern of one phthirapteran species infesting of A. anseris. METHODS Ten birds were examined every month. Infested birds were deloused. The bird was placed in a polythene bag containing a wool of cotton soaked in chloroform (head protrude...

background: head lice infestation is one of the most common parasitic infections with a long history in the world . the purpose of this study was to determine the prevalence of head lice infestation among 3-6 years old children going to nursery schools in kashan, iran in 2009.   materials and methods: this cross-sectional study was performed on 1200 children having the age range of 3-6 years ol...

A major challenge for Atlantic salmon farming in the northern hemisphere is infestation by the sea louse parasite Lepeophtheirus salmonis. The most frequent method of controlling these sea louse infestations is through the use of chemical treatments. However, most major salmon farming areas have observed resistance to common chemotherapeutants. In terrestrial environments, many strategies emplo...

Populations of the Western Scrub-Jay (Aphelocoma californica) have bills specialized for feeding in their respective habitats. Populations in oak habitat have hooked bills, whereas those in pinyon habitat have pointed bills with a reduced maxillary overhang. Work on other bird species shows that the bill overhang is essential for efficient preening to control ectoparasites. Given the importance...

Transforming science findings into practical applications is presented in the specific case of using remote sensing to detect the presence of an infestation of grapevines. The vines of Napa Valley were attacked by the root louse, Phylloxera, in the 1990’s resulting in a very large loss of production. The spectral response of the vines can be causally linked to the disruption in the ecology of t...
