Abstract The kinetoplastid protozoan Leishmania spp. cause leishmaniasis, which clinically exhibit mainly as a cutaneous, mucocutanous or visceral form depending upon the parasite species in humans. The disease is widespread geographically, leading to 20 000 annual deaths. Here, leishmaniases in both humans and animals, reservoirs and sand fly vectors on the Caribbean islands are reviewed. Autochthonous human infections by Leishmania spp. were found in the Dominican Republic, Guadeloupe and Martinique as well as Trinidad and Tobago; canine infections were found in St. Kitts and Grenada; and equine infections were found in Puerto Rico. Imported human cases have been reported in Cuba. The parasites included Leishmania amazonensis, Le. martiniquensis and Le. waltoni. Possible sand fly vectors included Lutzomyia christophei, Lu. atroclavatus, Lu. cayennensis and Lu. flaviscutellata as well as Phlebotomus guadeloupensis. Reservoirs included rats, rice rats and mouse opossum. An updated study is warranted for the control and elimination of leishmaniasis in the region because some of the data are four decades old.

Recruitment of a specific cell population after Leishmania infection can influence the outcome of the disease. Cellular migration in response to Leishmania or vector saliva has been reported in air pouch model, however, cellular migration induced by Leishmania associated with host's blood and vector saliva in this model has not been described. Herein we investigated cellular migration into air pouch of hamster after stimulation with combination of L. chagasi and host's blood and Lutzomyia longipalpis saliva. Migration induced by saliva was 3-fold more than those induced by L. chagasi alone. Additionally, L. chagasi associated with blood and saliva induced significantly even more leukocytes into air pouch than Leishmania alone. L. chagasi recruited a diverse cell population; however, most of these cells seem to have not migrated to the inflammatory exudate, remaining in the pouch lining tissue. These results indicate that L. chagasi can reduce leukocyte accumulation to the initial site of infection, and when associated with vector saliva in the presence of blood components, increase the influx of more neutrophils than macrophages, suggesting that the parasite has developed a strategy to minimize the initial inflammatory response, allowing an unlimited progression within the host. This work reinforces the importance of studies on the salivary components of sand fly vectors of leishmaniasis in the transmission process and the establishment of the infection.

The aim of the current investigation was to study the characterization ofthe habitat of Aristolochia baetica L., an Ibero-Mauretanian species, present in Tessala Mount (West of Algeria). Twenty-fourphytoecological surveys were realized on eight stations (St1-St8) in which the species is present. The floristic inventory allowed us toidentify 68 species which are part of the floristic of A. Baetica, distributed in 31 botanical families; 6 biological and 19 biogeographicaltypes. The assessment of edaphic and plant data using correspondence factor analysis (CFA) and hierarchical ascending classification(HAC) showed that A. baetica is a member of plant training of scrublands and grows especially in stations at low heights with a highrate of limestone.

SUMMARYAmerican cutaneous leishmaniasis (ACL) is a complex disease with a rich diversity of animal host species. This diversity imposes a challenge, since understanding ACL transmission requires the adequate identification of reservoir hosts, those species able to be a source of additional infections. In this study we present results from an ACL cross-sectional serological survey of 51 dogs (Canis familiaris), where we used diagnostic tests that measure dog's exposure toLeishmaniaspp. parasites. We did our research in Panamá, at a village that has undergone significant ecosystem level transformations. We found an ACL seroprevalence of 47% among dogs, and their exposure was positively associated with dog age and abundance of sand fly vectors in the houses of dog owners. Using mathematical models, which were fitted to data on the proportion of positive tests as function of dog age, we estimated a basic reproductive number (R0±s.e.) of 1·22 ± 0·09 that indicates the disease is endemically established in the dogs. Nevertheless, this information by itself is insufficient to incriminate dogs as ACL reservoirs, given the inability to find parasites (or their DNA) in seropositive dogs and previously reported failures to experimentally infect vectors feeding on dogs with ACL parasites.
