Further Characterization Of A Secreted Lipase From The Human Pathogen Leishmania Donovani By Determining The Effect Of Various Metal Ions On Its Enzymatic Activity., Lana Hoertz

Pell Scholars and Senior Theses

Leishmania donovani, a protozoan parasite, is the causative agent of the often fatal disease visceral leishmaniasis. The current treatments available are minimal and toxic to the patient. It has been shown that these organisms exhibit lipolytic activity during their growth in vitro. Lipases are enzymes that are known to aid in the development and virulence of several pathogenic organisms such as Candida albicans and Staphylococcus warneri. Little information is known, however, about the role of lipases in Leishmania species. We hypothesize that lipase may play a part in Leishmania's ability to survive within the human host as well as its …
