Revisiting the Acanthamoeba species that form star-shaped cysts (genotypes T7, T8, T9, and T17): characterization of seven new Brazilian environmental isolates and phylogenetic inferences
(CAMBRIDGE UNIV PRESSNEW YORK, 2012)
Free-living amoebae of the genus Acanthamoeba are the agents of both opportunistic and non-opportunistic infections and are frequently isolated from the environment. Of the 17 genotypes (T1-T17) identified thus far, 4 (T7, ...
Serine-like proteolytic enzymes correlated with differential pathogenicity in patients with acute Acanthamoeba keratitis
P>Acute ocular infection due to free-living amoebae of the genus Acanthamoeba is characterized by severe pain, loss of corneal transparency and, eventually, blindness. Proteolytic enzymes secreted by trophozoites of virulent ...
Citologia de impressão no diagnóstico de infecção corneana por Acanthamoeba: relato de caso
(Conselho Brasileiro de Oftalmologia, 2007-03-01)
To describe three cases of corneal infection due to Acanthamoeba sp in which was possible to detect Acanthamoeba sp cysts by the corneal impression cytology technique. Three patients referred to the External Eye Disease ...
Genotyping, physiological features and proteolytic activities of a potentially pathogenic Acanthamoeba sp isolated from tap water in Brazil
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
Acanthamoeba spp., known to cause keratitis and granulomatous encephalitis in humans, are frequently isolated from a variety of water sources. Here we report for the first time the characterization of an Acanthamoeba sp. ...
Growth, encystment and survival of Acanthamoeba castellanii grazing on different bacteria
Free-living amoebae of the genus Acanthamoeba are widely distributed in soil and water collections, where trophozoites (vegetative, multiplicative stages) feed mainly by phagocytosis and thus control bacterial populations ...
