Turismo de risco em áreas vulneráveis para a transmissão da esquistossomose mansônica no Brasil

“…For the N doses, according to the regression equation ( Figure 1B), the SD was negatively influenced, with reductions on the order of 5.33 and 4.10% for every 30% increase in the N dose, at 120 and 180 DAT, respectively. These results agree with those obtained by Souza et al (2016), who studied the effects of N doses on guava development and observed that the highest N doses also caused higher reduction in stem diameter. As observed for stem diameter, leaf area also suffered linear reduction as a function of the increase in soil salinity, with reductions of 9.59 (120 DAT) and 6.41% (180 DAT) per unit increase in the ECse (dS m -1 ) of the soil ( Figure 1C).…”

“…The experimental design was in randomized blocks distributed in a 5 x 4 factorial scheme, with three replications. The treatments were composed of five levels of electrical conductivity of the saturation extract - ECse (2.15,3.15,4.15;5.15 and 6.15 dS m -1 ), and four doses of nitrogen fertilization (378.7, 541.1, 703.4 and 865.7 mg of N dm -3 of soil), corresponding to 70, 100, 130 and 160% of the recommendation of Souza et al (2016). The values of electrical conductivity of the soil saturation extract were based on the threshold salinity of the crop (ECse = 1.2 dS m -1 ).…”

“…In this context, several studies indicate a positive effect of the interaction between water salinity and nitrogen fertilization, in castor beans, Guedes Filho et al (2015) in sunflower crops. However, Silva et al (2017), evaluating the effects of irrigation with saline waters (ECw: from 0.3 to 3.5 dS m -1 ) on the formation of rootstocks, and Paluma and Souza et al (2016), also studying the irrigation with saline waters and nitrogen doses on Crioula guava during the formation of rootstocks, did not find a beneficial effect of this interaction on the growth and quality of guava rootstocks.…”

“…However, the acute infection is self-limited and so these travelers may return home without presenting typical signs of infection. Timely treatment of the disease is thus delayed, which contributes towards its spread into disease-free areas, given that travelers move between endemic and non-endemic areas (Barreto et al, 2016).…”

Análise multivariada da esquistossomose no estado de Minas Gerais: análise de componentes principais

“…Alguns estudos têm demostrado o risco de transmissão urbana da esquistossomose em função da presença do hospedeiro intermediário, o caramujo do gênero Biomphalaria 20 . O fenômeno foi detectado no estado de Pernambuco onde o êxodo rural levou indivíduos parasitados para regiões urbanas com vetores da parasitose, porém persiste a elevada prevalência em áreas rurais, pois os hábitos socioculturais e condições sanitárias favorecem os processos de transmissão da doença 21 . Em Minas Gerais, a prevalência da parasitose na área rural ainda é significativa, pois apesar da população rural deste estado ser de 14,7% no período avaliado, 42,01% das notificações de esquistossomose eram de residentes da área rural 22 .…”
