“…Other species, such as Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia whitmani (Antunes & Coutinho, 1939) are important insect vector of Leishmania braziliensis , the etiological agent of cutaneous leishmaniasis (CL) in southeastern of Brazil. These three species of sand flies show a considerable degree of adaptation to altered environments and anthropophilic behavior regarding their food [11,12,13,14,15,16]. Other species of sand flies have been suspected of being vectors of Leishmania , for example, Nyssomyia neivai Pinto, 1926; Evandromyia sallesi Galvão & Coutinho, 1939; and Psychodopygus lloydi Antunes, 1937 [15].…”

Leishmaniases are a set of parasitic diseases of zoonotic origin that are transmitted by sandfly vectors in wild, rural and urban environments. Their distribution is dependent not only the distribution of vectors, but also on the distribution of mammalian reservoirs. Only by understanding the transmission cycle of these diseases, such as knowing the participating vectors and reservoirs, can one can understand the epidemiology and ecological relationships of leishmaniases. Ecotourism has become an important area of economic growth in Brazil. One of the most visited tourist attractions in the state of Minas Gerais, the Reserva Particular do Patrimônio Natural Santuário do Caraça (RPPNSC) is located in the Quadrilátero Ferrífero. The aim of this study was to contribute to the control of leishmaniasis among tourists of the RPPNPC by surveying its sand fly fauna and testing for the presence of Leishmania DNA in females. Twenty-five CDC light traps were exposed on 7 trails of the RPPNPC where samples were collected bimonthly for a year, starting in June 2013. A total of 376 specimens of 18 species and 10 genera of sandflies were captured. The predominant species were Psychodopygus lloydi (72.34%) and Pintomyia monticola (5.59%). HaeIII restriction enzyme detected and characterized Leishmania braziliensis DNA in 2 of the samples for an infection rate of 0.7% (2/266). Recent studies found specimens of Ps. lloyd infected with Leishmania braziliensis elsewhere in Minas Gerais, which may be an indication that this species is involved in the transmission of Leishmania in this state.

Malaria is one of the exclusion criteria used in selecting tissue donors and the absence of this information can lead to rejection of tissues for transplant. The studies on the malaria parasite have been confined to low dose attenuation of parasites in blood for transfusion purposes. There is no published information relating to the inactivation of malaria parasites with irradiation for the sterilisation of tissues. A dose-surviving parasite population following radiation was replotted using D value from a published paper whereby D value of 41 Gy was obtained. Calculation of sterilisation dose for achieving SAL 10 of malaria parasites demonstrated the effectiveness of the sterilisation dose of 25 kGy being used in tissue banking.
