“…Also in Italy, a description of a single case of a simultaneous infection with L. infantum and N. caninum in a dog with a skin infection was reported. The authors concluded that the immunosuppressive effect of L. infantum may have contributed to the development of the N. caninum infection; however, based on histological features, the skin lesions observed were most likely due to Leishmania (Tarantino et al 2001).…”

Uninfected dogs and those naturally infected with Leishmania chagasi exhibiting different clinical forms of disease were evaluated for the presence of anti-Neospora caninum and anti-Toxoplasma gondii antibodies. Blood samples were collected from 110 mongrel dogs. Sera were tested using the indirect fluorescent antibody test (IFAT), and the animals with visceral leishmaniasis (VL) (n=60) were classified clinically. Out of the 110 sera investigated, 5 (4.5%) were positive for N. caninum (IFAT≥50) and 36 (32.7%) for T. gondii (IFAT≥16). Anti-L. chagasi antibody titers in asymptomatic dogs (n=10) were found to be significantly lower (P<0.05) than those in oligosymptomatic ones (n=22), which were in turn significantly lower (P<0.05) than those in symptomatic ones (n=28). No association between Leishmania and N. caninum infections was observed. Among dogs infected with L. chagasi, a tendency (P=0.053) towards an association between the infection with T. gondii and the appearance of VL symptoms was observed, suggesting that the clinical manifestation of VL in dogs may enhance their susceptibility to T. gondii. The possible influence of the immunosuppressive status of canine leishmaniasis in the different clinical forms of the disease is discussed.

“…Co-infection of L. infantum and N. caninum (Cringoli et al 1996, Tarantino et al 2001, Cringoli et al 2002, Andreotti et al 2006 and between these parasites and T. gondii (Gennari et al 2006) has been investigated. Some studies have suggested that the immunosuppression caused by Leishmania sp.…”

“…In canine visceral leishmaniosis, the presence of amastigotes in different organs is usually observed in a background of inflammation (Martı´nez-Moreno et al 1995;Tarantino et al 2001). On the other hand, animals living in areas where the disease is endemic, particularly in tropical countries, are often subjected to arthropod bites, and to contact with other parasites that also cause inflammation in the skin (Tarantino et al 2001).…”

In this work we examined 76 stray dogs from an area of endemic visceral leishmaniosis, in order to determine whether the presence of skin inflammation or a specific inflammatory pattern could be taken as indicative of infection with Leishmania chagasi, and whether the parasite burden in the skin could be associated with the intensity or the nature of the inflammatory process. Inflammatory infiltrates were observed in the skin of 51 out of 55 animals with diagnosis of leishmaniosis, and in 17 out of 21 animals without signs of infection. Amastigotes were identified in the skin of 29 out of the 55 animals with diagnosis of leishmaniosis. Granuloma and a monomorphic macrophage inflammatory infiltrate, and not a mixed focal or mixed diffuse inflammation, were significantly associated with skin parasitism, both in terms of frequency ( P=0.015 in the Chi-square test) and intensity ( P=0.005 in the Kruskal-Wallis test). A low parasite burden was associated with a multifocal inflammatory pattern.

“…Clinical signs have been observed as early as six months of age (Tarantino et al, 2001;Lombardo et al, 2014), but often it takes more than a year for a susceptible dog to develop the first clinical signs or clinicopathological abnormalities following natural exposure to sandflies bites in an endemic setting .…”
