Presence of Cryptosporidium spp. and Giardia duodenalis in drinking water sampl...
Almeida, André; Moreira, Maria João; Soares, Sónia; Delgado, Maria de Lurdes; Figueiredo, João; Silva, Elisabete; Castro, AntónioCryptosporidium and Giardia are 2 protozoan parasites responsible for waterborne diseases outbreaks worldwide. In order to assess the prevalence of these protozoans in drinking water samples in the northern part of Portugal and the risk of human infection, we have established a long term program aiming at pinpointing the sources of surface water, drinking water, and environmental contamination, working with the...
Schistosoma haematobium and bladder cancer: what lies beneath?
Botelho, Mónica Catarina; Machado, José Carlos; Costa, José Manuel Correia daSchistosoma haematobium is a parasitic flatworm that infects millions of people, mostly in the developing world, and is associated with high incidence of bladder cancer although why is not clear. But our group was able to define the mechanistic relationship for the first time between infection of S. haematobium and cancer. We used in vitro models to demonstrate the presence of informative carcinogenesis-associa...
Biological and genetic characterization of Cryptosporidium spp. and Giardia duo...
Almeida, André; Moreira, Maria João; Soares, Sónia; Delgado, Maria de Lurdes; Figueiredo, João; Silva, Elisabete; Castro, AntónioTo understand the situation of water contamination with Cryptosporidium spp. and Giardia spp. in the northern region of Portugal, we have established a long-term program aimed at pinpointing the sources of surface water and environmental contamination, working with the water-supply industry. Here, we describe the results obtained with raw water samples collected in rivers of the 5 hydrographical basins. A total...
