Use of dried blood sample for serological diagnosis of toxoplasmosis in goats
AbstractEluates of 183 dried caprine blood samples on filter paper were tested for anti-Toxoplasma gondii antibodies, using IFA, ELISA and dot-ELISA, and compared with results obtained by direct observations on comparable sera, usin the same tests. The results has showed that papers with dried blood can be preserved for up to 45 days at room temperature and for six months at 4°C, provided they are protected against humid conditions by using desiccating agents such as silica-gel. Comparison between serum and eluate reactions revelated 97-100% correspondance. The antibody titers remained constant throughout the study period.
