Just found out it is in my system. What can you tell me about it and hiv together, and can it be passed via sexual contact?

A significan fraction of adults are toxoplasma antibody positive (Toxo IgG+) indicating past exposure/infection to the toxoplama parasite (such as through cat litter box contact). For most patients that poses no immediate risk. If a person is HIV infection and has a damaged immune system (such as a CD4 count < 150-100) then the toxoplasma organism could activate and cause a serious infection (often in the brain). For HIV+ patients with a CD4 count < 200, use of sulfa/trimethoprim prophylaxis for Pneumocystis often provides good protection against toxoplasmosis as well. Most HIV specialist are well versed at preventing and/or diagnosing toxo infections. KH
