Abstract:

Objective

To investigate the infection of pathogenic bacteria of neonatal pneumonia, and the drug resistance of pathogenic bacteria.

Methods

The pathogen detection and drug susceptibility results of sputum from 398 cases with neonatal pneumonia were analyzed in our hospital.

Results

The specimens positive rate was 56.28%, a total of 243 pathogenic bacteria were isolated with 176 (72.53%) strains of Gram-negative bacteria, Gram-positive bacteria 64 (26.34%) strains and 3 (1.23%) strains of fungus were isolated. The drug resistance rates of Gram-positive bacteria antimicrobial were higher in cephalosporins, with the rate of 3.7%-100%. Gram-negative bacteria had higher antimicrobial drug resistance to ampicillin, aztreonam, ceftazidime and other drugs , with the rates of 25%-100%.

Conclusions

Neonatal pneumonia patients had high antibacterial resistance to Gram-negative bacterium to ampicillin, aztreonam, cephalosporins ceftazidime with the high sensitivity of tazobactam and imipenem, in the clinical treatments should choose sensitively drugs.

Key words: Newborn, Pneumonia, Pathogenic bacteria, Drug resistance
