title: Enumeration of Pseudomonas species and Pseudomonas aeruginosa bacteriophages in domestic sewage.
abstract: Domestic sewage in Kuwait is mainly treated by an activated sludge process. Pseudomonas species were enumerated at all steps of sewage treatment. About 98-99% reduction in the number of these bacterial species were found in the treated effluent compared with raw sewage, which indicates a rather efficient removal of Pseudomonas from sewage. Spherical tail-less phages of Pseudomonas aeruginosa were found in all sewage samples. About 25-85% of the total phages encountered with the raw sewage were retained in the treated effluents. Seasonal variations of Pseudomonas spp and P. aeruginosa phages in two treatment stations are reported.
