The objective of this study was to investigate the extent of contamination of some of the most used paper denominations of the Egyptian currency (25 PT). Sixty-nine bills in circulation were collected from November 2003 through January 2004. A swab from each bill was cultured on nutrient agar and incubated at 37°C for 48?h. Results showed that over 65% of these bills had a bacterial count above 5.0?cm 2 . A preliminary identification of organisms present on these paper notes was done using selected Petri dishes with well-defined colonies. [ABSTRACT FROM AUTHOR]
