ABSTRACT
Free-living amoebae (FLA) are protozoa which have been reported in different countries worldwide from diverse sources (water, soil, dust, air), contributing to the environmental microbiological contamination. Most of the FLA species present a life cycle with two different phases an active vegetative and physiologically form named trophozoite, and an extremely resistant phase called cyst. Acanthamoeba spp., Naegleria fowleri, Balamuthia mandrillaris, Sapinia pedata, Vahlkampfia spp., Paravahlkampfia spp. and Vermamoeba vermiformis have been reported not only as causal agents of several opportunistic diseases including fatal encephalitis or epithelial disorders, but also as capable to favour the intracellular survival of common pathogenic bacteria, which could avoid the typical water disinfection systems, non-effective against FLAs cysts. Even though Santiago Island possesses high levels of humidity compared to the rest of the archipelago of Cape Verde, the water resources are scarce. Therefore, it is important to carry out proper microbiological quality controls, which currently do not contemplate the FLA presence in most of the countries. In the present work, we have reported the presence of Acanthamoeba spp. (69.2%); Vannella spp. (15.4%); Vermamoeba vermiformis (7.7%) and the recently discovered Stenamoeba dejonckheerei (7.7%) in different water sources of Santiago Island.
