Abstract:
Objective Use the automatic microbiological analysis system which for the streptococci (ATB rapid 32 Strep) to identify streptococci, and compare the examination speed and accuracy with the internationally recognized bacterium identification golden method API 20 Strep (streptococci identification biochemistry system) to enable the clinical microorganism room use ATB rapid 32 Strep identification system correctly, and provide the etiology basis to clinical promptly.Methods Isolate the bacterium from patient blood, cerebrospinal fluid, pig heart, pork and so on, then separate the streptococci in form to the blood plate, lay them in carbon dioxide incubator, after 35 ℃ 24 hours. Use ATB rapid 32 Strep,API 20 Strep and the traditional manual method to identify 18 strains of bacterias and carry on the medicine sensitive experiment.Results ATB rapid 32 Strep identified 16 strains as streptococcus suis II, 2 strains as streptococcus bovis II; API 20 Strep identified 17 strains as streptococcus suis II, 1 strain can not be identified; the tradition manually method identified all of the 18 strains as streptococcus group D . These 18 strains all sensitive to the Chloramphenicol , clindamycin, erythromycin, levofloxacin, penicillin, quinupristin/dalfopristin, cefotaxime, vancomycin and sulfafurazole , and resistant to the tetracyclin.Conclusion ATB rapid 32 Strep can identify the streptococcus suis in 4 hours , and the coincidence rate with API 20 Strep is 94.4%.So ATB rapid 32 Strep is one kind of system which could identify bacterium simply,quickly,accurately,and provide infectious disease etiology information for clinical immediately, satisfy the requirement of clinician and the microorganism examines.
