Detection of methicillin-resistant staphylococcus in elderly patients with chronic bronchitis / 国际检验医学杂志

ABSTRACT

Objective To study the infection situation of methicillin‐resistant staphylococcus in the elderly patients with chronic bronchitis and to analyze its drug resistance .Methods The included cases adopted the French Biomerieux API bacterial automatic analysis software to conduct the throat swab culture and identification .Then in 362 isolated strains of staphylococcus ,the distribu‐tion rule and drug resistance of methicillin‐resistant staphylococcus strains were retrospectively analyzed .Results Among 362 iso‐lated strains of staphylococci ,171 strains were methicillin‐resistant staphylococcus ,the isolation rate was 47 .23% ,its resistance to levofloxacin ,oxacillin ,clindamycin ,azithromycin ,cefepime ,piperacillin/tazobactam had statistical difference compared with those of coagulase negative staphylococcus(P<0 .05) .Conclusion Methicillin‐resistant staphylococcus is an important pathogen in elderly patients with chronic bronchitis ,and has multi‐drug resistance to commonly used antibiotics ,therefore using antibiotics according to the drug susceptibility test results is the key to effective anti‐infection treatment .
