undergo co-infection by Bdellovibrio and bacteriophage. Although the Bdellovibrio rounding of prey is thought to be evolved to reduce co-infection of multiple Bdellovibrio, larger prey that do not round may be infected by multiple Bdello's. Genomics The genome of Bdellovibrio bacteriovorus HD100 was sequenced in 2004. The HD100 genome is nucleotides long, larger than expected given its small size.
