Studies on bacteria in the gut of insect species are numerous, but their focus is hardly ever on the impact on host performance. We showed earlier that Erwinia bacteria occur in the gut of western flower thrips, most probably acquired during feeding. Here, we investigate whether thrips gain a net benefit or pay a net cost because of these gut bacteria. On a(More)
Topical treatment, with drug-containing ointments, of cutaneous leishmaniasis caused by Leishmania major in BALB/c mice was studied. Twenty chemotherapeutic agents having potential or established antileishmanial activity were formulated in different ointment and cream bases. Only 15% paromomycin sulfate with 12% methylbenzethonium chloride, 12% benzethonium(More)
Cutaneous leishmaniasis (CL) is one of the most important causes of chronic ulcerative skin lesions. The disease is endemic in many parts of the world, presenting a range of clinical forms - acute, chronic, recurrent and diffuse(1). Several species of Leishmania are involved, including L. major, L. tropica and L. aethiopica in the Old World, and several(More)
It has been shown that many insects have Enterobacteriaceae bacteria in their gut system. The western flower thrips, Frankliniella occidentalis Pergande [Thysanoptera: Thripidae], has a symbiotic relation with Erwinia species gut bacteria. To determine if other Thripidae species have similar bacterial symbionts, the onion thrips, Thrips tabaci, was studied(More)
OBJECTIVE To compare thoracic radiographs of clinically normal dogs and dogs with mild clinical heartworm disease with images transmitted by a desk-top, two-way audiovisual teleconferencing system. DESIGN Prospective, matched-set study. STUDY POPULATION 50 thoracic radiographs from clinically normal and heartworm-infected dogs and the digitally(More)
Several analogs of the glutathione (GSH) oxidizing reagent diamide [diazenedicarboxylic acid bis(N,N'-diethylamide)] were tested as radiosensitizers of aerobic cells. In general, radiosensitization correlates with the rate of reaction with cellular reducing agents and occurs only when the reductive capacity of the cell is exceeded. SR-4077,(More)
