Tick-borne relapsing fever (TBRF) has been reported in Eurasia and attributed mainly to Borrelia persica, although other entities have also been described. Ornithodoros tholozani is the most important tick vector, found in India and Kashmir, the southern countries of the former USSR, Iran, Iraq, Syria, Jordan, Turkey, Israel, Egypt, and Cyprus. It inhabits(More)
Myiasis is the infestation of tissues and organs of animals and humans by certain Dipteran fly larvae. This phenomenon is well documented in the skin, especially among animals and people in tropical and subtropical areas. Oral myiasis is a rare condition and can be caused by several species of Dipteran fly larvae and may be secondary to serious medical(More)
BACKGROUND Cutaneous leishmaniasis (CL) is a zoonotic disease, endemic and notifiable in Israel. The vectors are sandflies of the genus Phlebotomus, the hosts are mainly field rodents. The infective agents are Leishmania parasites. Ph. papatasi is the recognized vector of L. major, while Ph. sergenti is considered to be the vector of L. tropica. AIM To(More)
T relapsing fever (TBRF) is caused by Borrelia species and is transmitted to humans by Ornithodoros soft ticks. Worldwide, a dozen Borrelia species are known to cause this disease (1). In Israel, TBRF is considered to be caused by Borrelia persica and transmitted by the cave tick Ornithodoros tholozani (1). This tick and TBRF are distributed through Central(More)
The basic efficacy of lambda-cyhalothrin was tested in the laboratory against newly colonised adult Culex pipiens and field-collected Culicoides imicola. C. imicola was found to be more susceptible (LD(50)=0.0098%) than Cx. pipiens (LD=0.0233%); the efficacy against both species was definitely higher than that of cyhalothrin. Lambda-cyhalothrin showed(More)
Purpose. External ophthalmomyiasis (EO) is caused by infesting larvae belonging to various species of flies. Most documented cases result from sheep (Oestrus ovis) and Russian (Rhinoestrus purpureus) botfly larvae, but we recently discovered a rare case of EO caused by flesh fly (Sarcophaga argyrostoma) larvae. Here, we report the case of a patient with EO(More)
The customary method for controlling leishmaniasis and sand fly bites in Israel is the spraying of large quantities of residual insecticides on walls of houses and neighboring surfaces. However, the high summer temperatures, strong radiation, and dust limit the efficacy of the method. The sand fly vectors of Leishmania appeared to come uphill to the village(More)
New findings on the geographical distribution and ectoand endoparasites of Rattus norvegicus, Rattus rattus, and Mus musculus were recorded in 1999-2000. Seven specimens of R. rattus were trapped in the coastal plain of Israel, six of these in the Haifa area and one in Tel Aviv. Up to this record, the coastal plain was known to harbor only R. norvegicus. An(More)
The baseline and residual activity of micro-encapsulated insecticides was assessed on a sandfly colony originating in the Jordan Valley, Israel. Lethal doses were calculated for formulations of the pyrethroids permethrin and cypermethrin and the organophosphates diazinon and chlorpyrifos. Cypermethrin was found to be more toxic than permethrin and(More)
