Abstract

Balamuthia mandrillaris is a causative agent of granulomatous encephalitis that almost always proves fatal. A major concern during the course of therapy is that B. mandrillaris can transform into cysts. Cysts are highly resistant to physical and chemical conditions and present a problem in successful antimicrobial chemotherapy. However, the underlying mechanisms of B. mandrillaris transformation into cysts are not known. In this study, we examined the effects of exogenous sugars on B. mandrillaris encystment. The findings revealed that free exogenous galactose, but not other sugars, enhanced parasite differentiation into cysts, and apparently a galactose-binding protein is involved in B. mandrillaris encystment. Cytoskeletal re-arrangements and phosphatidylinositol 3-kinase (PI3K)-mediated pathways are involved in B. mandrillaris encystment based on inhibitor studies. Dual functionality of galactose-binding protein in B. mandrillaris pathogenesis and encystment is discussed further.
