“…Several studies have demonstrated that cats constitute sources of blood for sand flies (Johnson et al, 1993;Ogusuku et al, 1994;Maroli et al, 2009;Afonso et al, J HELLENIC VET MED SOC 2017, 68(1) ΠΕΚΕ 2017 2012; Baum et al, 2013). Τhe ability of the vector to properly complete feeding on cats and acquire infection has been indirectly proved after the experimental demonstration of infectiousness of two infected cats to sand flies (Maroli et al, 2007;da Silva et al, 2010).…”

In this study we aimed to determine the prevalence of Leishmania spp infection and to report the geographical distribution of Leishmania spp infected cats from Thessaly, central Greece, an endemic region for canine and human leishmaniosis. Blood samples were collected from a total of 150 cats (34 stray and 116 owned) from the area of Thessaly, i.e. Larissa (n=6), Volos (n=94), Trikala (n=30) and Karditsa (n=20). Data on signalment and living conditions were registered for each cat. The samples were tested by Internal Transcribed Spacer 1 nested PCR (ITS1 nested PCR). Geographical Information System (GIS) was used to define the geographical distribution of the Leishmania spp infected cats in relation to the land uses and the altitude. In total, 13.3% (95% CI: 8.3-19.8) of the sampled cats were found positive for Leishmania spp DNA. More precisely, the results are 12.8% (95% CI 6.8-21.2) in Volos, 20% (95% CI 6.8-21.2) in Trikala and 10% (95% CI 12-31.7) in Karditsa while none of the six cats examined from the region of Larissa was found PCR positive. The Leishmania spp infected cats were found in artificial surfaces and associated areas and in cultivated and managed areas with a mean altitude of 81,7 m above sea level (range 14 - 225 ± 51.57 SD). No significant correlation was found between Leishmania spp infection and signalment or living conditions, thus suggest ing that the infection is uniformly distributed among the screened feline population. The findings of this study along with the occurrence of competent vectors of Leishmania infantum in Thessaly, support the hypothesis that cats may serve as a reservoir for Leishmania spp in this region and highlight the need for surveillance in feline population and implementation of control measures. However, the epidemiological role of cats in the maintenance and transmission of Leishmania spp has yet to be defined and deserves further investigation.

“…A study in Colombia 12 , an endemic area for visceral leishmaniasis, suggested that L. longipalpis displays low anthropophily but is attracted to dogs, and based on this information the authors discuss the local epidemiology. A study in Peru 13 , showed the eclectic feeding habits of L. peruensis and L. verrucarum, although the former was more anthropophilic. A recently study on the stomach content of L. longipalpis with the precipitin test provided information backing the hypothesis on the transmission of visceral leishmaniasis in an anthropic environment in the municipality of Raposa, Maranhão State, Brazil 14 .…”

The precipitin test was applied to identify the blood meal sources of Lutzomyia intermedia, collected in two distinct habitats: inside houses and in the peridomicile, in Mesquita, Rio de Janeiro State, Brazil, a transmission area of Leishmania (V.) braziliensis. The following antisera were tested: human, avian, equine, rodent, and opossum. From a total of 370 females analyzed, 128 specimens from the domicile and 59 from the peridomicile reacted with specific antisera. The anthropophily of L. intermedia was confirmed in both habitats; likewise, the feeding of this sand fly species on domestic animals, observed in previous entomological surveys, was confirmed by the strong reactivity with avian, canine, and equine antisera. However, feeding on rodents, mammals frequently found inside and around houses, represents further evidence related to the vector competence of L. intermedia, since synanthropic and sylvatic rodents have been considered a putative reservoir of L. (V.) braziliensis.

“…97,153 This index, usually estimated by the detection of dog antigens (by ELISA or the precipitin test) in wild-caught, blood fed sand flies, 153 will depend on the relative abundance of dogs (in comparison with other potential blood meal sources), sandfly host preferences, and the accessibility of dogs to sand flies. 97,[153][154][155][156] Accessibility is determined by factors such as sandfly dispersal [157][158][159] and dog ecology. This may explain why, for example, ZVL prevalence has been found to be higher in hunting dogs than in urban/domestic dogs.…”

Abstract. Originally associated with forested areas, the transmission cycle of American cutaneous leishmaniasis (ACL) has now adapted to the domestic environment in at least 9 Latin American countries. Several studies have suggested that the domestic dog (Canis familiaris), which is already incriminated as the primary reservoir host of zoonotic visceral leishmaniasis (ZVL), may have a reservoir role in the domestic transmission of human ACL caused by Leishmania braziliensis, L. panamensis, and L. peruviana. This article reviews more than 90 studies reporting ACL infections in dogs, and concludes that as yet there is only circumstantial evidence to support that claim. Almost no data are available on the infectiousness of dogs to sandfly vectors of ACL, and there are few indications that either dog ownership or dog abundance are risk factors for ACL. Nevertheless, it has been proposed that incidence of ACL in humans could be reduced by targeting infected dogs. While this control strategy has been used for many decades against ZVL in Latin America, Europe, and Asia, there is little evidence to demonstrate its effectiveness either in theory or in practice. Particular concerns over the sensitivity and specificity of diagnostic tools, low compliance rates among dog owners, and cost-effectiveness are likely to apply equally to ACL control.The leishmaniases are a group of zoonotic diseases transmitted to humans and animals by the bite of phlebotomine sand flies (Diptera: Psychodidae). Despite their multiple etiologies, the New World leishmaniases can be divided into two broad categories: zoonotic visceral leishmaniasis (ZVL) and American cutaneous leishmaniasis (ACL).1 The latter includes localized cutaneous, mucocutaneous, and diffuse cutaneous leishmaniasis. Whereas ZVL is almost exclusively caused by Leishmania chagasi (L. infantum), ACL is caused by several Leishmania species, of which L. braziliensis is the most widespread. Many sandfly species have been incriminated as vectors of ACL throughout its geographic range, but reservoir hosts have only been identified for L. amazonensis, L. mexicana, L. guyanensis, and L. panamensis, and are unknown or unproven for both L. braziliensis and L. peruviana. 1 Originally associated with forested areas, 2 the transmission cycle of ACL has now adapted to the domestic environment due to deforestation and urbanization. 3,4 The transition from sylvatic to domestic transmission cycle was further encouraged by the lack of a specific leishmaniasis control strategy, and the discontinuation of intervention campaigns designed for other infectious diseases, e.g., malaria. 5,6
