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.

Pediculus humanus capitis, the head louse, is an obligate blood-sucking ectoparasite that occurs in six divergent mitochondrial clades (A, D, B, F, C and E). Several studies reported presence of different pathogenic agents lice specimens collected worldwide. These findings suggest louse could be a dangerous vector serious public health problem. Herein, we aimed to study genetic diversity, PHUM5...

OBJECTIVE To compare the pediculicidal activity of Ovide lotion and its active ingredient, 0.5% malathion, with Nix and its active ingredient, 1% permethrin, in permethrin-resistant head lice. DESIGN In vitro pediculicidal product and active ingredient comparison. The presence of knockdown resistance-type mutations (T929I and L932F) was validated by DNA sequencing.
