Modelling of the distribution of Biomphalaria glabrata and Biomphalaria straminea in the metropolitan region of Recife, Pernambuco, Brazil

Abstract: The occurrence of schistosomiasis is directly linked to the presence of its snail intermediate host Biomphalaria spp. Knowledge of geographical distribution, habitats and behaviour of these snails in relation to the climate is essential for guiding measures for disease prevention and control. This study aims to model the distribution of B. glabrata and B. straminea in schistosomiasis non-endemic areas of the metropolitan region of Recife (MRR) based on environmental data and estimates of snail distributions in… Show more

“…5 In Brazil, Schistosoma mansoni is traditionally considered to be endemic in rural areas. However, there has been an increase in the number of cases reported in coastal areas of the metropolitan region of Recife, [6][7][8][9] as well as in urban areas of the cities of Belo Horizonte, Salvador and Aracaju. [10][11][12][13] The appearance of cases of the disease in urban areas is not evidence of local transmission of S. mansoni, as it may be the result of infected migrants coming from endemic areas.…”

“…Schistosomiasis is an infectious disease that affects 1.8 million people in Brazil, and most federal states of Brazil are affected by S. mansoni [29,30,31]. Previous studies have demonstrated that the intermediate host B. straminea plays an important role in the transmission of S. mansoni [32,33,34]. Phylogenetic analyses clustered B. straminea from South China with Brazilian strains.…”
