Boring, J. R., Ill (Emory Univ. School of Medicine, Atlanta, Ga. 30303), W. T. Martin and L M. Elliott. Isolation of Salmonella typhi-murium from municipal water, Riverside, California, 1965. Amer J Epidem 93: 49–54, 1971.—Salmonella typhimurium phage type 2 was isolated from six different samples of the municipal water of Riverside, California, during an epidemic involving over 16,000 persons. Five isolations were made using the membrane filter technique and large volumes of water. One additional isolation was made by direct inoculation of water in enrichment medium. A sample containing water from all parts of the city was examined quantitatively; salmonellae were 10 times as numerous as E. coli.
