“…The association between mosquitoes and these diseases has stimulated researches on the fauna, geographic distribution and ecology of these insects, especially in areas with potential risk of pathogen transmission. In the State of Espírito Santo, the few existing studies on the fauna characterization and diversity of mosquitoes are directed to Anophelinae subfamily and areas of potential risk of malaria (Andrade & Brandão 1957, Deane et al 1968, Natal et al 2007, Meneguzzi et al 2009, Rezende et al 2009a, b, 2013, Silva et al 2013). In the mountainous region of Espírito Santo, where sporadic cases of malaria are notified, studies have incriminated Anopheles (Kerteszia) cruzii Dyar & Knab, 1908 as the main vector of Plasmodium vivax (Grassi & Feletti, 1890) (Rezende et al 2009b(Rezende et al , 2013.…”

Mosquitoes comprehend a group with a major impact on public health, because some species transmit parasites vertebrate hosts. Comparative studies between preserved environment and disturbed areas provide important epidemiological information, due to the major knowledge on species populational dynamics and the possibility of a contact between vector species and human population. This work aims to characterize and compare the fauna of mosquitoes in the Goytacazes National Forest (GNF) and surrounding area, in the State of Espírito Santo, in Brazil. Collections occurred simultaneously in a preserved environment and in a peridomicile, from 15:00 to 18:00, between July 2008 and May 2009. In each environment, it was used a modified trap of Shannon type. As a result, 1,490 specimens from 14 genera and 19 identified species were collected. The species diversity (H = 1.95), species richness (S = 17), equitability index (J = 0.68) and the number of collected specimens (n = 1,100) were higher in the forest environment. The plentiful species were respectively Aedes (Ochlerotatus) scapularis (Rondani, 1848), Culex (Culex) nigripalpus Theobald, 1901 and Aedes (Ochlerotatus) fulvus (Wiedemann, 1828). Our results demonstrate that the occurrence of vector species in this region increases the potential risk of diverse arboviruses occurrence, especially wild-type yellow fever.

“…The importance of free-range chick- ens for the epidemiology of toxoplasmosis is also related to the fact that their meat is a source of infection for humans and other animals (Hill and Dubey, 2013). Remote sensing and geographic information systems (GIS) are useful for the analysis of environmental factors related to the spatial distribution of infectious diseases (Meneguzzi et al, 2009;Silva et al, 2011;Djokič et al, 2014), and the risk maps emanating from this kind of investigation can be used to implement measures for the control and prevention of such diseases (Meneguzzi et al, 2009). However, the few existing studies on georeferencing of T. gondii infection are based on the results of serological tests in goats (Djokič et al, 2014), in cats (Afonso et al, 2013) and in otters (Chadwick et al, 2013).…”

The environmental contamination of Toxoplasma gondii in an endemic area in Brazil was mapped by georeferencing isolates from chickens in farms in the Southeast of the state of Rio de Janeiro. Tissue samples obtained from 153 adult chickens were analyzed by the mouse bioassay for T. gondii infection. These animals were reared free-range on 51 farms in the municipalities of Rio Bonito and Maricá. The ArcGIS kernel density estimator based on the frequency of T. gondii-positive chickens was used to map the environmental contamination with this parasite. A questionnaire was applied to obtain data on the presence and management of cats and the type of water consumed. Of the farms studied, 64.7% were found to be located in areas of low to medium presence of T. gondii, 27.5% in areas with a high or very high contamination level and 7.8% in non-contaminated areas. Additionally, 70.6% kept cats, 66.7% were near water sources and 45.0% were in or near dense vegetation. Humans used untreated water for drinking on 41.2% of the farms, while all animals were given untreated water. The intensity of environmental T. gondii contamination was significantly higher on farms situated at a distance >500 m from water sources (P=0.007) and near (≤500 m) dense vegetation (P=0.003). Taken together, the results indicate a high probability of T. gondii infection of humans and animals living on the farms studied. The kernel density estimator obtained based on the frequency of chickens testing positive for T. gondii in the mouse bioassay was useful to map environmental contamination with this parasite.

Ainda considerando-se o mesmo bioma, vale assinalar que o mosquito Anopheles darlingi, vetor primário na Região Amazô-nica, pode também participar da dinâmica de malária na Mata Atlântica, pois o limite de distribuição geográfica do inseto atinge o sudoeste do Estado do Paraná (Coutinho, 1947;Deane, 1986;Zimmerman, 1992;Rosa-Freitas et al, 1998;Pedro e Sallum, 2009).…”
