first report of vermamoeba vermiformis in the island of el hierro, canary islands, spain

background: free-living amoebae (fla) are group of protozoa distributed worldwide in many habitats mainly water and soil related sources. some members of fla are able to act as opportunistic pathogens and are environmental carriers of other pathogenic agents such as bacteria and viruses. vermamoeba vermiformis is a highly abundant fla species in water bodies and has recently gained environmenta...

Evaluation of Acanthamoeba isolates from environmental sources in Tenerife, Canary Islands, Spain.

Tests for potentially pathogenic amoebae were carried out in order to determine the presence of free-living amoebae of genus Acanthamoeba in soil and beach sand sources related to human environments in Tenerife, Canary Islands, Spain. Acanthamoeba identification was based on the morphology of cyst and trophozoite forms and PCR amplification with a genus specific primer pair. The pathogenical po...

Neoparamoeba branchiphila infections in moribund sea urchins Diadema aff. antillarum in Tenerife, Canary Islands, Spain.

A total of 109 sea urchins from 3 species collected in 2 localities off the coast of Tenerife Island, Spain, were examined for the presence of free-living amoebae in their coelomic fluid. Amoeba trophozoites were isolated exclusively from moribund individuals of long-spined sea urchins Diadema aff. antillarum (Philippi) (Echinoidea, Echinodermata) that manifested lesions related to sea urchin b...

Natural and Acquired Soil Quality along Environmental Gradients (tenerife, Canary Islands, Spain)

Abstract Tenerife Island, has a wide environmental diversity due to its altitude (3718m at its highest point) and to the climatic differences between its windward and leeward slopes. This work studies the changes in the natural soil quality along environmental gradients on the Tenerife Island and how this natural quality is modified by man’s effect on the ecosystem. For this purpose, a total of...

Zeolites in Pyroclastic Deposits in Southeastern Tenerife (canary Islands)

-The chemical and the mineralogical composition of a group of pumiceous tufts associated with recent salic volcanic episodes from Tenerife (Canary Islands) have been studied. The investigation focused on the two main types of pyroclastic deposits of the zone: ash-flows and ash-falls. The samples can be classified chemically as trachytic and phonolitic rocks with an intermediate silica content a...
