54.  Zakaria El Astal.  Increasing Ciprofloxacin Resistance Among Prevalent Urinary Tract Bacterial Isolates in Gaza Strip, Palestine.  Journal of Biomedicine and Biotechnology.  2005:3 (2005) 238–241.

This is a study to investigate the incidence of Ciprofloxacin resistance among Urinary Tract infection bacterial isolates.  1278 urine samples were collected and the disk diffusion method was used for antibiotic resistance.  492 (38.5%) showed positive anti-microbial cultures.  The resistance was 15% to ciprofloxacin.   The bacterial species that was most resistance to ciprofloxacin was Acinetobacter haemolyticus (28.6%), Staphylococcus saprophyticus (25%), Pseudomonas aeruginosa (20%), Klebsiella pneumonia (17.6%), and Escherichia coli (12%).  There is an increased bacterial resistance to ciproflaxcin and this could be attributed to inappropriate use of the antibiotic.
