new findings on anaplasmosis caused by infection with anaplasma phagocytophilum.ixodes ricinus (i. ricinus) is one of the vectors of anaplasma phagocytophilum (a. phagocytophilum) in europe, in which rates of infection range from 1.9% to 34%. in 1998, human granulocytic ehrlichiosis-like (hge-like) ehrlichia dna was detected in italy, by pcr technique in one i. ricinus nymph out of 55 ticks that were examined. in 1996, 6.3% of 310 human sera in high-risk subjects from italy were found positive for antibodies to ehrlichia phagocytophila (e. phagocytophila). in the same year, ...200617135539
anaplasmosis in cattle in italy.bovine anaplasmosis caused by anaplasma marginale is a disease transmitted by ticks belonging to the ixodidae family. southern italy is considered an endemic zone but environmental and social factors are changing the epidemiology of the disease to expand to previously anaplasmosis-free regions. the available data of published reports of anaplasmosis in italy together with the data obtained by the national centre of reference for anaplasma, babesia, rickettsia and theileria (, allow ...200717682850
prevalence of borrelia burgdorferi sensu lato genomospecies and of the human granulocytic ehrlichiosis (hge) agent in ixodes ricinus ticks collected in the area of monti lepini, italy.ticks are obligate hematophagous arthropods that are parasites in every class of vertebrates in most regions of the world. they are also considered to be important vectors for the transmission of human infectious diseases. in the present study we used polymer chain reaction (pcr) amplification analysis to determine the prevalence of borrelia burgdorferi and ehrlichia phagocytophila, the agents of, respectively, lyme borreliosis and human granulocytic ehrlichiosis, among ticks inhabiting the area ...200312797900
