The link between bacteria and eukaryotic cells found in sewage???

Scientists from Germany and Ireland have been studying types of bacteria that are prominent in bogs and sewage plants to research the link between bacteria cells and cells with a nucleus, the eukaryotes. Prior to these studies it was widely suggested that there was perhaps not some intermediate cell, rather a type of fusion of cells to create a new cell. Researchers have found that PVC (Planctomycetes, Verrucomicrobiae, Chlamydiae) bacteria are all types that might be the intermediate step between bacteria and eukaryotes since they are larger and divide more slowly. Further reasearch will be needed to be able to determine if the fusion theory or intermediate theory is more likely.
