Abstract
NUNEZ, . Juan Francisco et al. Evaluation of two different potency tests for leptospirosis vaccine vax-SPIRAL®. Rev Cubana Med Trop [online]. 2005, vol.57, n.1, pp. 67-68. ISSN 1561-3054.
Two different potency tests were evaluated, consisting in one-dilution used to determine 50 % lethal dose (LD50) and four-dilution used to calculate 50 % effective dose (ED50), respectively. Our experience has led to propose the four-dilution test for routine lot releasing.
