Leishmania infantum Seroprevalence in Cats From Touristic Areas of Italy and Greece

Leishmaniosis by Leishmania infantum is a major zoonotic Vector-Borne Disease (VBD) in terms of geographic distribution, pathogenicity and zoonotic potential. While dogs are the main reservoir of L. infantum, the infection in cats is poorly understood although increasingly reported from enzootic and non-enzootic areas. The Mediterranean basin is a key area for leishmaniosis and includes touristic spots that require continuous surveillance for VBDs in consideration of the growing tendency of tourists to travel with their pets. This study evaluated L. infantum seroprevalence in cats living in selected touristic localities of Italy and Greece. A total of 269 cat serum samples from three Sites i.e., 76, 40, and 153 from Adriatic Coast of Abruzzo, Italy (Site A), Giglio Island, Tuscany, Italy (Site B), and Mykonos Island, Greece (Site C), respectively, were included in the survey. Sera samples were subjected to an indirect immunofluorescence antibody assay for the detection of anti-L. infantum specific IgG. Associations between possible risk factors and seropositivity to L. infantum were statistically evaluated. Antibodies against L. infantum were detected in eight out of 269 (3.0%) cats tested i.e., 4/76 (5.3%), 1/40 (2.5%), and 3/153 (2.0%), from sites A, B, and C, respectively. A statistical association between anti-L. infantum antibodies and cohabitation with dogs was shown. This study indicates that feline populations living in the examined Italian and Greek touristic areas are exposed to L. infantum and that they may contribute to the circulation of L. infantum, enhancing the risk of infection for dogs and humans

Strongylid nematodes shared between domestic and wild ruminants in the Maiella National Park (Abruzzo region, central Italy)

INTRODUCTION. Strongylid nematodes (SN) are recognized as a major concern to livestock production. As the control of SN relies heavily on the use of parasiticides, anthelminthic resistance (AR) is increasing (Barone et al., 2020 Vet Parasitol. 279: 109041). It is known that wild ruminants may harbor several SN that typically infect livestock andit is assumed that they couldalso act as reservoirs in the translocation of anthelmintic resistance (Chintoan-Uta et al., 2014 Proc Biol Sci. 281: 20132985). This risk is even increased where domestic and wild ruminants graze on the same pastures. The aim of the present study was to obtain novel information on the distribution of SN in sheep and wild ruminants (i.e. red deer, chamois) sharing the same pasture in the Maiella National Park. MATERIALS AND METHODS. A total of 20 faecal pool samples were collected from sheep (n. 7) and wild ruminants (n. 13) and examined by classic copromicroscopic tests. Gastrointestinal strongyle (GIS) positive pools were subjected to coprocolture. L3s were morphologically and molecularly identified (Gasser et al., 1993 Nucleic Acids Research. 21: 2525-26; van Wyk et al., 2013 Onderstepoort J Vet Res. 80: 539). RESULTS AND CONCLUSIONS. Thirteen faecal pools were positive for GIS and 16 pools for bronchopulmonary strongyles (BPS) (Table 1). The present data confirm that wild ruminants may harbor strongyle species that usually affect sheep (Zaffaroni et al., 2000 Vet Parasitol. 90: 221-30). Further studies are required to investigate the pattern of transmission of strongyles between domestic and wild ruminants and the role of wildlife in the spread of anthelmintic-resistant nematodes
