Extraintestinal nematodes of the red fox (Vulpes vulpes) are a wide group of parasites that infect wild and domestic carnivores and occasionally humans. Nematodes in the cardiopulmonary system, stomach, urinary apparatus and muscle tissue of 165 red foxes (Vulpes vulpes) from north-west Italy (Liguria and Piedmont) were investigated between 2009 and 2012.(More)
An epidemiological survey for the monitoring of bovine tuberculosis transmission was carried out in western Liguria, a region in northern Italy. Fifteen Mycobacterium bovis strains were isolated from 63 wild boar samples (62 from mandibular lymph nodes and 1 from a liver specimen). Sixteen mediastinal lymph nodes of 16 head of cattle were collected, and 15(More)
Although rare in developed countries, most acquired human cases of hepatitis E virus (HEV) infection are associated with travel to developing countries where HEV is endemic. Increasingly, however, sporadic, non-travel-related HEV cases have been reported in developed countries. In Italy, only two studies to date have investigated the presence of HEV in wild(More)
An epidemiological survey was carried out on the distribution of canine leishmaniasis in Western Liguria (Northern Italy). Blood sera from 21146 dogs collected from 1990 to 1996 were subjected to the indirect immunofluorescence test (IFAT). From 1990 to 1994 (16690 dogs), only monthly seroprevalences were calculated (min 14%-max 60.5%). Dog sera sampled(More)

Three recombinant antigens of Leishmania chagasi (= L. infantum) were expressed in prokaryotic systems and evaluated (using a panel of dog sera characterized by parasitological and serological immunofluorescent antibody test [IFAT] techniques) as diagnostic markers of infection. The whole open reading frame encoding K9, the gene fragment encoding the(More)
Meat products from HEV-infected reservoir animal species are capable of transmitting HEV to humans and represent a public health concern. Human HEV cases have been linked to the consumption of raw or undercooked pig liver sausages, pork, and game meats, such as wild boars and deer worldwide. Direct exposure to swine or wild game species might also represent(More)
In this study we compared a commercial enzyme linked immunosorbent assay (ELISA) rapid test (Snap CLATK Canine Leishmania Antibody Test Kit, IDEXX-Snap) with indirect immunofluorescence assay (IFA) and Western blot (WB) for the detection of Leishmania infantum antibodies in dogs. In total sera from 234 dogs were collected: 59 positives and 51 doubtful sera(More)
We report the results of a survey to determine the prevalence of canine leishmaniasis and the presence of sand flies in northwestern Italy, where autochthonous foci of canine leishmaniasis have not been reported. Active foci of canine leishmaniasis were identified, which suggests that the disease is now also endemic in continental climate areas.
A detailed macroscopic and histological description is given of tuberculous-like lesions in mandibular lymph nodes obtained from wild boar (Sus scrofa) collected in Italy during the 1995/1996 hunting season, as well as a correlation with results obtained from a Mycobacterium tuberculosis complex target amplified test system. According to macroscopic(More)
Sera from fifty free-ranging red foxes (Vulpes vulpes) from the Imperia province, Liguria, Italy, were examined for antibodies against Leishmania spp. by both immunofluorescence assay (IFA) and enzyme linked immunosorbent assay (ELISA), from January to May 1992. Nine of 50 animals (18%) had antibodies against Leishmania spp. utilizing both IFA and ELISA(More)
