[Parasitocenoses in natural foci of hemorrhagic fever with renal syndrome in the Maritime Territory].

A complex of possible vectors and reservoirs of infection in nature has been investigated in five different nidi of hemorrhagic fever with the renal syndrome in the Primorje territory. 2455 ixodid ticks, 19 458 trombiculid mites, 10 942 gamasid mites and 2138 fleas were collected from 1700 small mammals. It has been established that every investigated nidus differs in a peculiar specific composition and ratio between small mammals and their ectoparasites.

Studies on Bancroftian filariasis in Liberia, West Africa. III. Efficacy of repeated treatment with diethylcarbamazine and vector control on the microfilarial reservoir in a rural population.

The population of four villages in the savanna area in Upper Lofa in the hinterland of Liberia was treated with diethylcarbamazine and the decline of the density of microfilariae of Wuchereria bancrofti was studied. It became obvious that even a repeated treatment with the drug did not result in a complete eradication of the parasites, but that about one third of microfilaria carriers who had received two courses of treatment remained infected, showing ultra low densities which could only be-discovered by employing the sensitive membrane filtration technique. Vector control by means of residual spraying with DDT carried out every six months for 2 1/2 years in two villages did not result in a decrease of the microfilaria carrier rates. However, the microfilarial density of the infected persons declined distinctly during the three years of control. Experiences made with the membrane filtration technique under field conditions are described.

Arbovirus surveillance in Italy.

A high number of different arboviruses have been demonstrated to be present in Italy, due to the coexistence of climates that are characteristic of continental areas in the North of the country and of subtropical areas in the South. Viruses circulating in Central Europe, such as the Tick-Borne Encephalitis (TBE) virus, are present in Central and Northern Regions, whereas viruses circulating in Mediterranean areas, such as the Sandfly fever viruses are present in Central and Southern Italy. Viruses have been isolated from mosquitoes, ticks, sandflies and vertebrates (birds, rodents, humans). For some of them an association with human disease has been demonstrated.
