When DDS and E-test methods were compared in respect of their value" in determination of ESBL production, DDS method was better than the other in determination of ESBL negative strains whereas E-test method in positive strains.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:In this study, extended spectrum beta-lactamase (ESBL) production was investigated in a total of 610 Escherichia coli, 212 Klebsiella pneumoniae, 68 K. oxytoca and 26 K. ozanae isolates by double disk synergy (DOS) and E-test methods.

Abstract

In this study, extended spectrum beta-lactamase (ESBL) production was investigated in a total of 610 Escherichia coli, 212 Klebsiella pneumoniae, 68 K. oxytoca and 26 K. ozanae isolates by double disk synergy (DOS) and E-test methods. ESBL production was positive in four of E. coli isolates by E-test and in 21 by DDS whereas in 31 of K.pneumoniae isolates by E-test and in 40 by DDS methods. However, neither K. oxytoca nor K. ozanae isolates were shown to be producers of ESBL. When DDS and E-test methods were compared in respect of their value" in determination of ESBL production, DDS method was better than the other in determination of ESBL negative strains whereas E-test method in positive strains.

Özet

Bu çalışmanın amacı, hastanede izole edilen Escherichia coli ve Klebsiella suşlarında genişlemiş spektrumlu beta-laktamaz (ESBL) varlığını araştırmak idi. Hastanede izole edilen 610 E. coli, 212 K. pneumoniae, 68 K. oxytoca ve 26 K. ozanae izolatında çift disk sinerji ve E-test yöntemleri kullanılarak ESBL üretimi araştırıldı. Escherichia coli izolatlarının E-test yöntemi ile dördünde çift disk sinerji(ÇDS) yöntemi ile 21 'inde; K. pneumoniae izolatlarının ise E-test yöntemi ile 31'inde, ÇDS yöntemi ile 40'ında ESBL pozitifliği saptandı, Klebsiella oxytoca ve K. Ozanae izolatlarında ESBL üretimi saptanmadı. Genişlemiş spektrumlu beta-laktamaz üretiminin saptanmasında ÇDS yöntemi ve E-test yöntemi kıyaslandığında, ÇDS yönteminin özellikle ESBL yönünden negatif olan olguları saptamada, E-testin ise pozitif olguları saptamada daha değerli oldukları görüldü.
