N. Foster et al., ISOLATION, CHARACTERIZATION AND PROTECTION STUDIES IN MICE OF A STREPTOMYCIN-DEPENDENT MUTANT OF STREPTOCOCCUS-SUIS TYPE-1 2/, Veterinary research communications, 18(3), 1994, pp. 155-163
An avirulent, streptomycin-dependent (Str-D) mutant of Streptococcus s
uis type 1/2 was produced and characterized by its antimicrobial susce
ptibility, growth kinetics, biochemical reactions and reversion rate.
Homologous and heterologous vaccine trials in mice resulted in complet
e protection against challenge with S. suis types 1 and 1/2 and partia
l protection against challenge with S. suis type 2.
