study on immunobiology in ectoparasites of public health interest: rhipicephalus sanguineus.the recently defined range of mediterranean spotted fever (msf) in sardinia coincides with that of the widely studied rickettsia conorii vector, the brown dog tick rhipicephalus sanguineus. this tick is major vector of disease in humans, domestic and wild animals. characteristic features of the vector with respect to their seasonal activity, abundance as well as incidence of human-tick contact and how these factors influence the incidence of msf were studied. this paper also looks at host, patho ...200112078475
first direct detection of rickettsial pathogens and a new rickettsia, 'candidatus rickettsia barbariae', in ticks from sardinia, italy.the present study evaluated the molecular detection and identification of rickettsia species in 83 ticks collected in sardinia, italy. fifteen ticks were pcr-positive using glta-specific and ompa-specific primers, leading to the identification of rickettsia aeschlimannii in hyalomma marginatum marginatum, r. massiliae in rhipicephalus turanicus and in rhipicephalus sanguineus, and a new rickettsia, previously referred to as potirb169 in portugal, in four rhipicephalus turanicus. this new species ...200819040474
ticks infesting domestic animals in italy: current acarological studies carried out in sardinia and basilicata regions.the note reviews published and unpublished data on acaralogical studies carried out by different parasitologists' groups in sardinia and basilicata regions. in sardinia 72 collecting sites were investigated and a total of 4,086 ticks were collected from hosts (cattle, sheep, goats and pigs) and from soil. so far 2,413 ticks belonging to six genera have been identified: rhipicephalus (67.2%), haemaphysalis (24.1%), hyalomma (2.7%), boophilus (0.7%), dermacentor (4.9%), ixodes (0.3%). host-associa ...199911071541
