RESUMO

This study aimed to characterize Pseudomonas aeruginosa isolates in 2 intensive care units in Egypt and Saudi Arabia. P. aeruginosa isolates from patients' and staff hands and environmental samples were typed using antibiotyping and ERIC-PCR. In Egypt, isolates from suction apparatus tubing and drainage containers [A7] and AV tubing [A8] were linked to those from patients who had these antibiotypes. In Saudi Arabia, isolates from suction apparatus tubing [A6] and AV tubing [A7] were linked to patients with the same antibiotypes. In Egypt, patients' isolates had ERIC VII, VIII and IX patterns linked to suction apparatus tubing, AV machine tubes and drainage containers. In Saudi Arabia, patients' isolates had ERIC VIII and XI patterns linked to suction apparatus tubing and AV machines. In Egypt and Saudi Arabia, ERIC typing gave higher discriminatory indices [0.801 and 0.785 respectively] than the antibiotyping [0.7123 and 0.728 respectively]. ERIC was superior to antibiotyping and should be used in tracing sources of infection

RESUMO

There is a dearth of local information in Al Ain, United Arab Emirates about antibiotic resistance patterns. In this retrospective study in a tertiary referral hospital, antibiotic susceptibility results were analysed over the 5-year period 2004-08 and compared with a previous study in the same hospital during 1999-2002. Staphylococcus aureus showed a significant decrease in sensitivity to oxacillin from 95.0% in the period 1999-2002 to 84.4% in 2008. Sensitivity of Acinetobacter spp. to imipenem dropped from 99.0% in 2004 to only 32.5% in 2008. During the same period, almost half of Escherichia coli isolates developed resistance to cefotoxime. Significant reductions in sensitivity to Pseudomonas aeruginosa between 1999 and 2008 were found for almost all the antibiotics tested. Klebsiella spp. did not show any significant change in resistance to any of the tested antibiotics. Serious efforts are needed to reduce the risk of the spread of resistant strains of bacteria

RESUMO

Contamination of the operating theatre is a major cause of nosocomial infection. This study aimed to evaluate the incidence of bacterial contamination of operating theatres in Al Imam Ali Hospital in Baghdad, and the source of contamination. From 1216 swabs collected from surfaces, equipment and antiseptic solutions from different operating theatres in 2001 and 2002, the rates of positive cultures were 3.7% in 2001 and 4.0% in 2002. Staphylococcus epidermidis was the most common isolate in 2001 followed by Pseudomonas aeruginosa, whereas in 2002 coliform bacteria were the highest, followed by P. aeruginosa. No clear pattern of isolates was found in different types of operating theatres, although coliforms and P. aeruginosa were mostly found in the delivery theatre
