Evaluation of the Bactec 9240 system for blood cultures
No full textPurpose: This study was carried out in order to determine species of bacteria causing sepsis and the rate of false positives and negatives in the results obtained in the evaluation of blood cultures by the Bactec 9240 system. Method: For a period of one year, from September 1994 to September 1995, 8022 blood cultures which were taken by various clinics from patients with fever or sepsis were evaluated using the Bactec 9240 system. For this purpose, Bactec plus Aerobic/F and Bactec Peds plus/F vials were examined for 7 days. Identification of the bacteria was made using the Sceptor system. Results: Out of the 8022 blood cultures, 1763 were positive with the Bactec 9240 system and of these, 1727 grew in the subcultures (2.05% false positives). As a result of subculturing of the 6259 blood cultures negative in the Bactec system, various bacteria and fungi were isoleted in 11 cultures (0.18% false negatives). The majority of the bacteria isolated were Staphylococcus species. Besides this, out of the 1763 cultures that were positive with Bactec 9240, 19 (1.08%) were positive after the 5th day. Conclusion: The time involved in the evaluation of blood cultures is shortened when the Bactec 9240 system is used. Also, there is less contamination of the blood cultures since subculturing is done only once
Aerobik bakteriemi etkenlerinin izolasyonunda bactec 9240 sisteminin değerlendirilmesi
No full textBACTEC 9240 otomatik kan kültürü sistemi; aerop bakterileri izolasyondaki başarısı, duyarlılığı ve spesifikliği yönüyle değerlendirilmek amacıyla retrospektif olarak incelendi. İncelenen 1118 örnekten 428'inde (% 38.3) üreme sinyali vardı ve bunların aerobik subkültürlerinin 410'unda (% 36.7) üreme oldu. On sekiz örnekte (% 1.6) ise yalancı pozitiflik vardı. Sistemin negatif olarak bildirdiği hiçbir örnekte subkültürlerde üreme olmadı. Sistemin duyarlılığı % 100.0, özgüllüğü 96.0 idi. Bu mikroorganizmaların 58'i (% 5.2) kontaminasyon olarak kabul edildi. Patojen kabul edilen 352 mikroorganizmanın 235'i (% 66.8) Gram-negatif, 114'ü (% 32.4) Gram-pozitif bakterilerdi ve üç örnekten (% 0.8) mantar izole edildi. En fazla izole edilen bakteriler Salmonella typhi (56), Staphylococcus aureus (44), Klebsiella pneumoniae (39) ve Escherichia coli (31) idi. BACTEC 9240; kullanışlı, duyarlı ve güvenilir bir sistem olarak kabul edilmiştir

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
