The free-living amoeba (FLA) group of protozoa that can be found in various types conditions nature, one which is the genus Acanthamoeba. Although, number infections caused by this protozoan low, diagnosis was still difficult to confirm and therefore there were a higher mortality, especially those associated with encephalitis. This review presents some information about biology, pathogenesis, c...

Introduction: Acanthamoeba is an opportunistic protist, which is ubiquitously distributed in the environment. Infection with Acanthamoeba spp. poses threat to human health, such as, Acanthamoeba keratitis (AK) that is a vision-threatening infection of the cornea. This study aimed to identify the species of Acanthamoeba strains isolated from cornea of keratitis patients by polymerase chain react...

This study evaluated the presence of Acanthamoeba species in the Puzih River watershed, which features typical subtropical monsoon climate and is located just above the Tropic of Cancer in Taiwan. The relationship between the seasonal and geographical distributions of Acanthamoeba species in this rivershed was also investigated. Acanthamoeba species were detected in water samples using the amoe...

Acanthamoeba keratitis is a vision-threatening infection caused by pathogenic species of the genus Acanthamoeba. Although not all Acanthamoeba spp. can cause keratitis, it is important to differentiate pathogenic species and isolates from nonpathogens. Since extracellular proteases may play a role in ocular pathology, we used colorimetric, cytopathic, and zymographic assays to assess extracellu...

Acanthamoeba is free-living protist pathogen capable of causing a blinding keratitis and granulomatous encephalitis. However, the mechanisms of Acanthamoeba pathogenesis are still not clear. Here, our results show that cells co-cultured with pathogenic Acanthamoeba would be spherical and floated, even without contacting the protists. Then, the Acanthamoeba protists would contact and engulf thes...
