| [virus transmission to man from phlebotomus flies: role of the tuscany virus (bunyaviridae, phlebovirus) in the etiology of infections of the central nervous system]. | during field studies on the ecology of arboviruses in italy, strains of a new virus were isolated from sand flies, mostly females, of a pure colony of phlebotomus perniciosus collected in a central italian region (tuscany). the prototype was named toscana (tos) virus, assigned to the phlebotomus fever serogroup of arboviruses (family bunyaviridae, genus phlebovirus) and registered in 1980 in the international catalogue of arboviruses. neutralizing antibodies to tos virus were detected in human s ... | 1988 | 3152279 |
| [sandflies in italy: observations on their distribution and methods for control]. | the paper analyzes published and unpublished data of sandfly collections carried out in italy by one of the authors (m.m.) over a period of 18 years (1975-1993). these data are discussed in relation to the collection methods and the habitats. the leishmaniasis foci surveyed are localized in 11 regions of central and southern italy and in the two main islands, sicily and sardinia. five collection methods were used: i) sticky traps, ii) light traps, iii) window exit traps, iv) emergence traps, and ... | 1994 | 7637994 |
| sandfly fever viruses in italy. | two serologically distinct agents, the sandfly fever sicilian and the sandfly fever naples viruses, were isolated by sabin from blood samples taken during an italian epidemic of febrile illness. since then, several different viruses have been isolated from sandflies and/or humans in both the old and new world. toscana virus, a new virus closely antigenically related to sandfly fever naples virus, was isolated in 1971 from the sandfly phlebotomus perniciosus in italy. extensive studies on the imp ... | 1996 | 8800804 |
| leishmaniasis in tuscany (italy): vii. studies on the role of the black rat, rattus rattus, in the epidemiology of visceral leishmaniasis. | the recent finding that four leishmania isolates from rattus rattus are enzymologically identical to l. infantum, aetiological agent of human and canine visceral leishmaniasis in the mediterranean area, has stimulated further research on the role of r. rattus in the epidemiology of visceral leishmaniasis in tuscany, italy. the present work has led to the following results: (a) r. rattus experimentally infected with l. infantum displayed a general resistance to the parasite, even though it appear ... | 1983 | 6636269 |
| man-bait catch of phlebotomus perniciosus (diptera, psycodidae) in a human and canine leishmaniasis focus in central italy. | man-bait catches of phlebotomus perniciosus were carried out in a human and canine leishmaniasis focus in central italy (monte argentario, grosseto) to evaluate the man-sandfly contact of this vector. p. perniciosus females were collected biting on man outside, during the first hours of the night, when the local people are at risk. the results of these captures are discussed and the man-sandfly contact is considered in relation to the epidemiological aspects of the disease in the area under stud ... | 1984 | 6599999 |
| ecology of viruses isolated from sand flies in italy and characterized of a new phlebovirus (arabia virus). | a total of 84 virus strains was obtained from 16,374 male and female sand flies (phlebotomus perniciosus and p. perfiliewi) collected in two localities of tuscany region in italy between 1980 and 1985. thirty-seven (44%) were identified as toscana virus (family bunyaviridae, genus phlebovirus) and 47 (56%) as a new member of the phlebotomus fever serogroup, arbia virus. the characteristics of this new serotype are described. the overall virus isolation rate from sand flies was 0.5 per 100 insect ... | 1988 | 3128131 |
| viruses transmitted by sandflies in italy. | five different phlebotomus-transmitted viruses have been isolated in italy. four of them belong to the bunyaviridae family (genus phlebovirus). sandfly fever sicilian and sandfly fever naples viruses were isolated from sick persons during world war ii, toscana and arbia viruses have been isolated more recently from phlebotomus perniciosus and p. perfiliewi. radi virus is the only phlebotomus-transmitted virus isolated in italy from p. perfiliewi, which belongs to the rhabdoviridae family (genus ... | 1991 | 1841253 |
