    ABSTRACT: Leishmaniasis, caused by Leishmania infantum, is an endemic zoonosis in the Mediterranean basin. Dogs are considered the major host for these parasites, as well as the main reservoir for human visceral infection. In recent years, asymptomatic infection or clinical disease caused by L. infantum in cats has been reported in several countries where zoonotic leishmaniasis is present. The aim of the present study was to perform a leishmaniasis survey in cats from an endemic focus. Twenty-three adult stray cats were surveyed by clinical examination, and peripheral blood samples for serological and molecular analysis were collected. In 7 of the 23 cats (30.4%) Leishmania DNA was detected in blood. A low level of fluorescent antibodies was detected in four serum samples. All the animals were asymptomatic. Taking into account the high rate of asymptomatic feline leishmaniasis in this survey, it can be suggested that cats may act as a habitual reservoir host of L. infantum infection in endemic areas. Furthermore, it will be important in the future to add this parasitosis to the differential diagnosis of feline infections from leishmaniasis foci in cats. Feline leishmaniasis diagnosis should be accessed by molecular tools.

    ABSTRACT: A case of leishmaniosis in domestic cats (Felis catus domesticus) is described. The subject showed a nodular lesion on the eyelid. The diagnosis was achieved by serological, parasitological, and light and electron microscopic investigations. By molecular techniques the aetiological agent was identified as belonging to Leishmania infantum, the species implicated in human and canine leishmaniosis in southern Europe. A preliminary study on the prevalence of asymptomatic feline leishmaniosis, performed in the areas where the infected cat was identified, revealed a low seroprevalence of infection: only 1 (0.9%) of the 110 cat sera examined by indirect fluorescent antibody test was positive for anti-Leishmania antibodies. Because clinical signs in feline leishmaniosis are unspecific and similar to those observed in other diseases commonly found in this species, leishmaniosis must be added to the differential diagnosis by feline veterinary practitioners and adequate serologic and histopathologic investigations must be performed in endemic areas.

    ABSTRACT: Greece is a highly endemic country for Leishmania species. Canine cases of leishmaniosis are recorded in different parts of the country. However, no case of feline leishmaniosis has been reported yet. In the present study, the seroprevalence in cats was investigated as a first approach to measuring Leishmania spp. infection of this animal species, in Greece. For this purpose, blood serum samples from 284 stray adult cats, living in the major area of Thessaloniki (Northern Greece), were examined by enzyme-linked immunosorbent assay for the detection of anti-Leishmania spp. IgG. Eleven (3.87%) of the examined animals were found positive. The prevalence was lower in cats than in dogs coming from the same area, based on previous studies. Despite the low seroprevalence for Leishmania spp. in cats, leishmaniosis may be taken into consideration concerning the differential diagnosis of the feline diseases, especially in endemic areas.
