Sc. Cowley et al., SUPPRESSION OF FRANCISELLA-TULARENSIS GROWTH IN THE RAT BY COINFECTION WITH F-NOVICIDA, FEMS microbiology letters, 153(1), 1997, pp. 71-74
We have previously shown that when cultured in vitro, peritoneal rat m
acrophages infected with Francisella novicida spontaneously release ni
tric oxide in sufficient quantities to inhibit bacterial growth. Howev
er, it is not known whether F, novicida can have a similar antimicrobi
al effect in vivo. Here we show that a co-infection of F. novicida wit
h Francisella tularensis can suppress the number of F. tularensis cell
s in rat spleens by as much as 100-fold.
