In this paper we use detailed data about the biology of the head louse (pediculus humanus capitis) to build a model of the evolution of head lice colonies. Using theory and computer simulations, we show that the model can be used to assess the impact of the various strategies usually applied to eradicate head lice, both conscious (treatments) and unconscious (grooming). In the case of treatment...

1 Senior Resident, 2 Assistant Professor Department of Microbiology DRPGMC Tanda. Abstract Dermatophytosis is a superficial fungal infection confined to the stratum corneum and appendages of the skin. Health education, timely diagnosis and treatment has brought down the fungal infection rate in developed countries but it is still common in developing countries. Tinea corporis refers to all the ...

Clinical images Day 5: widespread indurated truncal plaques due to Trichophyton rubrum superficial dermatophyte infection (A and B) Following chorioamnionitis, a male infant from a remote Indigenous community was born by vaginal breech delivery at 26 weeks’ gestation. On Day 5, indurated, vesicular and erythematous lesions were noted on extensive areas of the back (Box, A and B). Blue light (45...

Introduction Psoriasis is a frequent inflammatory skin disease affecting ~2%-3% of the population in western countries. Scaling of the psoriatic lesions is the most impairing symptom in patients with psoriasis. In contrast to conventional keratolytic treatment concepts containing salicylic acid or urea, a dimeticone-based medical device (Loyon®) removes scales in a physical way without any phar...

The domestic fly (Musca domestica) can carry the virus of poliomyelitis in an active state for several days upon the surface of the body and for several hours within the gastro-intestinal tract. Mosquitos (Culex pipiens, Culex sollicitans, and Culex cantator), in our experiments, have not taken up and maintained in a living state the virus from the spinal cord of monkeys. Lice (Pediculus capiti...

Trench fever is a body louse-borne disease caused by Bartonella quintana Brenner. The recent status of louse infestation in Nepalese children is not well known. We collected head and body lice, Pediculus humanus capitis De Geer and Pediculus humanus humanus L., respectively, from 30 children, including 11 cases of double infestation with both head and body lice. Detection of B. quintana in both...

Background: Tinea corporis is a superficial fungal infection of the glabrous skin of the trunk and extremities caused by closely related organisms of the three genera – Trichophyton, Microsporum, and Epidermophyton, collectively known as dermatophytes. The prevalence of the different species varies according to geographic and climatic regions. Trichophyton rubrum has been reported from various ...
