Analysis of the Pathogens Composition and Resistance of Pharynx-mop and Nonpharynx-mop Sample from In-patients in Chest-cardio Surgery Ward

Objective: To analyze of the pathogens composition and resistance of pharynx-mop and non- pharynx-mop sample from in-patients in chest-cardio surgery ward at Shanghai Chest Hospital, we explored the clinical meaning of pharynx-mop and non- pharynx-mop sample analyzing. Methods: The data on bacterial susceptibility testing of clinical isolates from Aug. 1,2002 to Jul. 31, 2003 were collected, and divided in two species for analysis, pharynx-mop sample and non- pharynx-mop sample. Results: A total of 386 strains were isolated from pharynx-mop sample, and 402 strains from non-pharynx-mop sample. They have more different in pathogens composition and resistance. The bacterial antibiotic-resistance from non-pharynx-mop sample is higher than from pharynx-mop sample. Conclusion: The result from pharynx-mop sample,examined immediately after in-patient, can not forecast the nosocomial infection. The increase and change of bacterial antibiotic-resistance from non-pharynx-mop sample show the usage of antibiotic unreasonable.
