Rj. Sandler et al., THE INHIBITION OF CLOSTRIDIUM-BOTULINUM TYPE-C BY OTHER BACTERIA IN WETLAND SEDIMENTS, Journal of wildlife diseases, 34(4), 1998, pp. 830-833
Bacteria with inhibitory activity against Clostridium botulinum type C
were isolated from 32% of sediment samples (n = 1600) collected from
10 marshes in a northern California wetland over a 12 mo period. Aerob
ic and anaerobic bacteria with inhibitory activity were isolated from
12% and 23% of the samples, respectively. Bacteria with inhibitory act
ivity were isolated from all 10 study sites and throughout the year. T
his study demonstrates that bacteria with inhibitory activity against
C. botulinum type C occur naturally in wetland sediments.
