Phagocytosis of Acanthamoeba sp. from aquifer of the Valley of Mezquital (State of Hidalgo, Mexico).
Original language description
Genus Acanthamoeba dominated among the amoebae isolated from underground waters in the Valley of Mezquital (State of Hidalgo, Mexico). Feeding activity of Acanthamoeba sp. xenic isolate was studied in micro-well plate experiments using fluorescently labelled bacteria (FLB) method. A dispersed bacterial prey (Enterobacter aerogenes) was applied at a concentration up 10^7 FLB ml-1. Within the incubation (less than 1 h), amoebae ingested in an average 2 to 4 FLB cell-1, i.e., uptake rates of 6 to 54 FLB cell-1 h-1 and 1 to 12 vac cell-1 h-1 were reached, respectively. Generally, ingestion of FLB dropped due to an apparent saturation within the first 10 to 30 min of incubation with FLB. Numbers of FLB collected by amoebae from a dispersion varied too muchto state a feeding rate valid for all populations, however, the data have proven that acanthamoebae are able to collect efficiently a bacterial food from the dispersion at concentrations higher than 10^6 cells ml-1.
