Summary: | Strain D 78 is the only vaccine against Gumboro disease currently available in Kinshasa (Zaire). This freeze-dried vaccine, conditioned in 1000 doses vials, is not adapted for small-holders (100 to 200 chickens) who either do not vaccinate or lose the unused doses. Stability of the vaccine in solution was investigated at + 4°Cand -20°C. At -20°C, the titer remained stable during six months while at + 4°C it lost 0.4 log10 TCID50 every 30 days. The possibility to use freezed vaccine are discussed. |
