Article Abstract:
The close proximity of the Sand Island Outfall is responsible for fecal pollution, in the form of coliphages and vibriophages, in the waters of Mamala Bay, Oahu, Hawaii. However, the quality of the recreational beaches at Mamala Beach is unaffected. The level of coliphage is higher in nonpoint coastal stations. The level of vibriophage is higher at the Sand Island Transect stations D1 and D2, and in eutrophic coastal environments. The level of coliphages and vibriophages is higher heavy rainfall than during dry season.

Article Abstract:
Four indigenous bacterial hosts obtained from concentrated water samples from Mamala Bay, Oahu, HI, were used to genetically characterize marine temperate phage-host systems. Two of the rod-shaped bacterial hosts were identified as Sphingomonas paucimobilis and Flavobacterium. All of the phage isolates were tailed phages and contained double-stranded DNA. Two of the phage isolates had morphologies typical of the family Siphoviridae while the other two belonged to the families Myoviridae and Podoviridae.

Article Abstract:
The indication of fecal pollution by measuring coliphage abundance is discussed. Water column and sediments from Florida Bay across Key Largo to the edge of the Florida Shelf were analyzed for total, coliphage and marine host isolate virus abundance by viral, sediment and bacterial direct counts. Results indicate that phage was abundant in the Key Largo during winter and that factors determining their distribution in the water column were different from from those in the sediments.
