Persistence of acanthamoeba antigen following acanthamoeba keratitis [PDF]

British Journal of Ophthalmology, 2001
To investigate the hypothesis that persistent corneal and scleral inflammation following acanthamoeba keratitis is not always caused by active amoebic infection but can be due to persisting acanthamoebic antigens24 lamellar corneal biopsy and penetrating keratoplasty specimens were obtained from 14 consecutive patients at various stages of their ...

Biology and pathogenesis of Acanthamoeba [PDF]

Parasites & Vectors, 2012
Acanthamoeba is a free-living protist pathogen, capable of causing a blinding keratitis and fatal granulomatous encephalitis. The factors that contribute to Acanthamoeba infections include parasite biology, genetic diversity, environmental spread and host susceptibility, and are highlighted together with potential therapeutic and preventative measures.

Acanthamoeba genotype T4 from the UK and Iran and isolation of the T2 genotype from clinical isolates [PDF]

, 2005
The majority of the keratitis-causing Acanthamoeba isolates are genotype T4. In an attempt to determine whether predominance of T4 isolates in Acanthamoeba keratitis is due to greater virulence or greater prevalence of this genotype, Acanthamoeba ...

ACANTHAMOEBA ENCEPHALITIS

Indian Journal of Medical Microbiology, 2008
Central nervous system infection with free-living amoebae is rare. We present a fatal case of Acanthamoeba encephalitis in a 63-year-old female from India where acanthamoebae were demonstrated and cultured from CSF. In spite of treatment with amphotericin B, fluconazole and rifampicin the patient did not survive.
