In this report we describe a selective pigment medium containing colistin and nalidixic acid that allows presumptive identification of S. agalactiae from the primary plate, even when specimens are polymicrobic. A preliminary study compared the value of three media for pigment production by 137 known S. agalactiae strains. This was followed by a clinical laboratory trial using the best of these pigment media at an obstetric hospital in which 581 specimens from neonates, female reproductive tracts, and urinary tracts were screened. Subsequent to the clinical laboratory trial, an epidemiological investigation using the selective pigment medium was conducted on a mother/infant population. Of the 1,331 specimens screened for S. agalactiae, 75 (5.6%) were positive on 5% sheep blood agar and 79 (5.9%) were positive on the selective pigment medium.</p>","PeriodicalId":76595,"journal":{"name":"The American journal of medical technology","volume":"49 11","pages":"807-11"},"PeriodicalIF":0.0,"publicationDate":"1983-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17419197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strategies for antimicrobial susceptibility testing of fastidious aerobic bacteria. 挑剔好氧菌的药敏试验策略。
The American journal of medical technology Pub Date : 1983-11-01

{"title":"Strategies for antimicrobial susceptibility testing of fastidious aerobic bacteria.","authors":"J Hindler","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>There are several \"non-standardized\" test methodologies for performing antimicrobial susceptibility tests on clinical isolates of fastidious aerobic organisms. Critical to the interpretation of a susceptibility test (or any clinical laboratory test) is correlation of the results with the clinical status of the patient. If previous extensive studies have not been performed for a given antimicrobial-organism combination using a specific method, the results must be interpreted with discretion. Even when documented correlative data are available, strict quality control measures must be followed to ensure optimal performance of the test system. Ideally, these include testing of quality control organisms of known susceptibilities similar to the test isolate. Such quality control strains of fastidious organisms are not readily available; however, they may be obtained through local health departments. In our laboratory, in order to inform clinicians of the limitations of the results generated from antimicrobial susceptibility testing of fastidious aerobic bacteria using non-standardized (not NCCLS) procedures, we have adopted a mechanism for reporting results of disc tests as \"presumptive\" (Figure 1). When reporting dilution test results that are derived using methods other than those described by the NCCLS dilution protocol, we indicate the modifications employed in the particular test (Figure 2). Our goals are to attempt to identify unusual resistance that may occur and to generate results that are as accurate, precise, and meaningful as possible, yet we must be aware of the limitations of the procedures with which we are working (Table V). It is only with these understandings that we can be of service to our clinicians and patients.</p>","PeriodicalId":76595,"journal":{"name":"The American journal of medical technology","volume":"49 11","pages":"761-7"},"PeriodicalIF":0.0,"publicationDate":"1983-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17478391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Colony counts and PSDA screening results were compared for 800 urine specimens. The PSDA method proved to be 92% specific, but only 64% sensitive, for detecting at least 10(5) colony forming units (CFU)/ml. By performing serial dilution colony counts on 109 culture-positive specimens (greater than or equal to 10(5) CFU/ml), it was determined that the low level of sensitivity (64%) was due to culture-positive specimens that had between 10(5) and less than 10(7) CFU/ml. The sensitivity of the PSDA method increased to 90% and 100% when culture-positive specimens had 10(7) or more and 10(8) or more CFU/ml, respectively.
