Pathogen distribution and drug resistance in pneumonias among immunocompromised hosts

Objective: To provide evidence for diagnosis and treatment by investigating the pathogens and drug resistance of immunocompromised host (ICH) pneumonias. Methods: Statistical method was used to analyze retrospectively the data of pathogens and drug resistance of ICH pneumonia treated in our hospital in 2014. Results: We confirmed 187 cases of ICH pneumonia by pathogen study of 324 patients. Gram-negative bacillus (68.42%) was the main pathogen of ICH pneumonia. Acinetobacter baumanii (AB) accounted for the first place. Staphylococcus aureus infection was still the first of Gram-positive coccus. Conclusion: Gram-negative bacillus was the main pathogen of ICH pneumonia in our hospital and the isolated bacteria show strong antibiotic resistance. Therefore, it is necessary to strengthen dynamic monitoring of pathogens in the secretions from ICH pneumonia patients' lower respiratory tract and drug resistance. It is suggested that clinicians make anti-infection treatment cover drug-resistant bacteria.
