Produksi dan Isolasi Protein Membran Stadium Bradizoit Toxoplasma gondii : Suatu Usaha untuk Mendapatkan Material Diagnostik dalam Mendiagnosa Toksoplasmo

Abstract

A study was conducted to isolate the membrane protein of Toxoplasma gondii at bradyzoid stage forthe development of intradermal diagnostic test in livestock infected by the parasite. Toxoplasma wasinitially collected from meat of goat serologically positive to the parasite. The infected meat was then fedinto uninfected cat to obtain oocyst. The oocyst was inoculated into the stomach of mice to produce tachyzoitwhich in turn produce cyst in tissue known as bradyzoit . The membrane protein was then isolated from thebradyzoit. The protein was analysed by sodium dodecyl sulfate electrophoresis (SDS-PAGE). The dataobtained were presented descriptively. The protein concentration isolated from each mouse infected at thedose of 1x107 oocysts was 11.91 mg. Two protein bands specific for bradyzoit were identified at 97.72 kDaand 67.60 kDa.
