CICUTTIN, Gabriel; DE SALVO, María  e  NAVA, Santiago. Hard Tick Species in a Protected Urban Area of Buenos Aires City. Rev. argent. salud pública [online]. 2017, vol.8, n.32, pp.7-12. ISSN 1852-7513.

INTRODUCTION: Ticks (Acari, Ixodida) are arthropod vectors of great diversity of viral, bacterial and protozoan pathogens, many of which are zoonotic and emerging. In Argentina, there are numerous hard tick species (Ixodidae family) which also parasitize humans. Protected urban areas are natural ecosystems located within or near large urban centers. The Costanera Sur Ecological Reserve (RECS) of Buenos Aires city shows a circulation of wild species that have no presence in other areas of the city. There are potential hosts and vectors. OBJECTIVES: A quantitative cross sectional study was carried to detect the species of ticks present in the RECS of Buenos Aires city. METHODS: A quantitative cross - sectional study was carried out by sampling to collect ticks from vegetation and hosts (rodents and dogs). RESULTS: In total, 1090 ticks were collected from the vegetation (454 of the species Amblyomma aureolatum, 635 Ixodes auritulus and 1 Amblyomma triste) and 67 from dogs (64 A. aureolatum, 2 Rhipicephalus sanguineus sensu lato and 1 A. triste). No ticks were detected in 200 examined rodents. CONCLUSIONS: Ticks species detected in this study are important for public health, because they are parasites of humans (A. aureolatum, A. triste and R. sanguineus s. l.) and participate in the cycle and transmission of different zoonotic pathogens in different regions of the world, including Argentina.
