Growth and Encystation of Acanthamoeba castellanii [PDF]
SUMMARY: Complete encystment of Acanthamoeba occurred in peptone-yeast extract-glucose medium supplemented with 50 mM-magnesium chloride. There was an increase in the RNA, protein and DNA contents of the cells which coincided with an increase in the proportion of binucleate amoebae and commitment to encystation, suggesting that encystation could be a ...

Phagocytosis and Pinocytosis in Acanthamoeba castellanii [PDF]
Endocytotic activity of Acanthamoeba trophozoites attenuates once the cells enter stationary phase in liquid culture. Phagocytosis, monitored by the ingestion of polystyrene latex beads, essentially ceases and the uptake of [3H]inulin, known to be mediated by pinocytosis, is reduced by about half.

Chemiluminescence of Acanthamoeba castellanii [PDF]
1. Chemiluminescence of Acanthomoeba castellanii in the presence of O2 was of similar intensity in organisms harvested early or late during exponential growth [when cyanide (1 mM) stimulates or inhibits respiration respectively]. 2. Cyanide (up to 1.5 mM) stimulated photoemission in both types of organism by 250–300 photons/s per 10(7) cells above the ...

The cytochromes of Acanthamoeba castellanii [PDF]
1. Low-temperature difference spectra of gradient-purified mitochondria of Acanthamoeba castellanii reveal the presence of cytochromes b-555, b-562 and c-549, with a-type cytochromes having a broad asymmetrical maximum at 602 nm; these components were also observed in specta of whole cells. 2.

Acanthamoeba castellanii, the causative agent of Acanthamoeba keratitis (AK), occurs mainly in contact lens users with poor eye hygiene. The findings of many in vitro studies of AK, as well as the testing of therapeutic drugs, need validation in in vivo ...

'Acanthamoeba' produces disseminated infection in locusts and traverses the locust blood-brain barrier to invade the central nervous system [PDF]
BACKGROUND: Many aspects of Acanthamoeba granulomatous encephalitis remain poorly understood, including host susceptibility and chronic colonization which represent important features of the spectrum of host-pathogen interactions.

Chorismate mutase peptide antibody enables specific detection of Acanthamoeba.
Accurate and rapid diagnosis of Acanthamoeba keratitis (AK) is difficult. Although the diagnostic procedure for AK has improved, further development and effective diagnostic tool utilization for AK need to continue.
