Semiantigen sulfamethoxydiazine (SMD) was coupled with carrier protein bovine serum albumin (BSA) to prepare complete antigen SMD BSA by glutaraldehyde method.
Drug sensitivity test showed that it was sensitive to ciprofloxacin, novobiocin, gentamycin and it was resistant to penicillin G, cefalexin, sulffadiazine sodium.
New research shows that it is ineffective to use sulfa drugs (including sulfapyridine and ethylamine) for preventing toxoplasma infection. 15 percent AIDS have toxoplasma.
