Occurrence of Staphylococcus aureus and Pseudomonas aeruginosa in Israeli coastal water.
The occurrence of Pseudomonas aeruginosa and coagulase-positive Staphylococcus aureus in seawater from beaches of central Israel was investigated from June 1983 until June 1985. P. aeruginosa was monitored in 652 samples of seawater from 34 beaches, and S. aureus was monitored in 628 samples. P. aeruginosa was found in 44.8% of samples (6.5% with 1 bacterium per 100 ml of water), and S. aureus was recovered from 60.7% of samples (5.3% with 1 organism per 100 ml), compared with 91.6% of samples with total coliforms (TC) and 82.2% with fecal coliforms (FC). The correlation between the presence of P. aeruginosa to that of TC and FC was 99.1 and 98.3%, respectively, while S. aureus was found in 4.3 and 8% of samples where TC and FC, respectively, were absent. Monitoring of S. aureus as a supplementary indicator in populated beaches is recommended because it will add valuable information on the sanitary quality of the seawater.
