Replication origins tend to be A-T rich in both bacteria and eukaryotes. A-T base pairs have two hydrogen bonds, as opposed to C-G pairs, which have three bonds. This means it is easier to separate the strands of the double helix in A-T rich regions than in regions with higher G-C content. Bacterial chromosomes are small, and only a single origin of replication is needed. Eukaryotic chromosomes are much larger, and there would not be enough time to complete replication if there were only one origin. Bacterial replication tends to be faster than eukaryotic replication (~45,000 bp/min vs. 2000-3000 bp/min).
