I believe all bacteria are haploid in terms of allele content.

However, in rich medium, some bacteria are replicating very rapidly, and so the chromosome will appear to be at multiple copies near the origin of replication. I think this can be seen in sequencing depth plots, but can't remember where I saw it (unless it was in original Church sequencing-by-ligation paper)
