“…Subsequently, large numbers of cercariae are released by molluscs at the primary focus of the disease. Thus, having higher water availability, populations of molluscs may increase and expand foci of dissemination and vulnerability to disease, because the points are studied in the region of high prevalence for fasciolosis, as verified by Freitas et al (2012). This situation is considered serious, since the beginning of the rainy season cattle leaving a little feeding and face a high infection by intake metacercariae on abundant grassland.…”

The population density of Lymnaea columella (Say, 1817) (Mollusca, Lymnaeidae) an intermediate host of Fasciola hepatica (Linnaeus, 1758), in the Caparaó microregion, ES, Brazil

The aim of this study was to monitor the population density of Lymnaea columella, an intermediate host of Fasciola hepatica, in various aquatic habitats and in drinking water in the area of the Instituto Federal de Educação, Ciência e Tecnologia do Espírito Santo, on Caparaó Microregion, municipality of Alegre, state of Espírito Santo, Brazil. Monthly samplings were performed at certain points between drainage areas and drinking water in cattle and goat production systems during the years 2010 to 2013. The mean temperature, precipitation and the frequency of samples of L. columella were analysed graphically according the monthly average during the study period. A total of 2,038 molluscs were collected, 1558 of which were L. columella, that predominated in all sampled points. The highest average of specimens observed for L. columella was in the years 2010 and 2013 (51.0), and occurred decreased in 2011 (19.8). The temperature and precipitation averaged is 23.7 °C and 141 mm/year, respectively. Rainfall peak occurred in March (2011, 2013) and November (2012, during these periods the population of L. columella growth. There was no significant difference in the relationship between the specimens observed with seasons (dry-wet), thus the population of L. columella remained stable and can be found throughout the year.

“…In this context, Freitas et al (2012) conducted a study in an area with the presence of snails of the genus Lymnaea located in the Alegre city, and using variables such as waterbody, slope, floodplains and grasslands, generate vulnerability maps for the occurrence of the disease and attributed all sites sampled in areas of greatest vulnerability risk, with percentages ranging 25-31%. In another study, Freitas et al (2014) observed through a zoning distribution for risk areas for fasciolosis that 52.24% of the entire state is in areas at risk for occurrence and survival of F. hepatica.…”

Climate change on the forecasted risk of bovine fasciolosis in Espírito Santo state, Brazil

et al. 2014

The climate change expected for the coming years can cause large economic losses and a strong impact on intestinal parasites of ruminants throughout the world. In this sense, organisms belonging to the class trematoda seem to be highly sensitive to any changes in the patterns of temperature and rainfall caused by possible climate change. So, maps were elaborated forecasting current and future risk to Fasciola hepatica in the state of Espírito Santo, Southeast of Brazil, using as a base increases in the temperature ranging from 1°C to 5°C. Environmental and climatic factors like temperature, rainfall, altitude and declivity were used for generation of maps bioclimatic risk of fasciolosis through of the ArcGIS/ArcInfo 10.1 Software. High-risk areas resulted in a total of 35.42% for the current risk and tended to decrease with increases in temperature over the next 100 years, which favored a reduction of 35.42% to 33.84% in these regions. The places included in the of low risk areas showed significant increases in their areas for temperatures up to 5°C with values ranging from 24.65% to 28.26% of their areas. These forecasting models using increases in temperatures in the generation of risk maps to F. hepatica were first made in Brazil and like the others, represented a tendency to aid in policy making animal and human health oriented regions shown to be potentially suitable for the risk of bovine fasciolosis.

Neste sentido, organismos pertencentes à classe Trematoda parecem ser altamente sensíveis a alterações nos padrões de temperatura e precipitação causados por eventuais alterações climáticas. Assim, foram elaborados mapas de previsão de risco atual e futuro para Fasciola hepatica no estado do Espírito Santo, Sudeste do Brasil, utilizando como base o aumentos na temperatura que variaram de 1°C a 5°C. Fatores ambientais e climáticos, como a temperatura, precipitação, a altitude e a declividade foram utilizados para a geração de mapas de risco para fasciolose por meio do programa ArcGIS / ArcInfo 10.1. As áreas de alto risco resultaram em um total de 35,42% para o risco atual e tenderam a diminuir com o aumento da temperatura para os próximos 100 anos, o que favoreceu uma redução de 35,42% para 33,84% nestas regiões.

“…Fatores como ausência de cobertura vegetal, a classe do solo, a intensidade de chuvas, dentro outros, associados à declividade, conduzirão a uma maior velocidade de escoamento, menor quantidade de água armazenada no solo e resultarão em áreas constantemente alagadas (FREITAS et al, 2012), gerando ambientes propícios para a proliferação de mosquitos (espécies de…”
