Invasions caused by free-living and parasitic limax amoeba can pose a major threat to human health and life. The amoeba from the genera Acanthamoeba and Naegleria as well as the following species: Sappina diploidea, S. pedata, Balamuthia mandrillaris, and probably Hartmannella vermiformis, are the major cause of primary amoebic meningoencephalitis (PAM), granulomatous amebic encephalitis (GAE) and amoebic keratitis (AK). Furthermore, free-living amoeba can be vectors of bacteria, including Legionella pneumophila, Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophila, Klebsiella pneumoniae, Serratia marcescens and Mycobacterium tuberculosis. There is a need for more research on free-living amoeba invasions in humans, particularly on the methods of diagnosis and appropriate forms of pharmacological therapy. Despite the undeniable role of free-living amoeba in the transmission of pathogenic bacteria, there is still insufficient amount of research and optimal diagnostic methods to identify the mechanisms of penetration, proliferation and exocytosis of many pathogenic microorganisms.
