Several phenotypic methods have been developed to detect or confirm ESBL production by … A comparison with the CLSI susceptibility test and the ESBL screen test was performed using a number of clinical isolates of E. coli and Klebsiella spp. To develop a phenotypic ESBL detection strategy, the Vitek 2 advanced expert system (AES) (version 5.01; AST N048 cards) and MIC breakpoints of several indicator cephalosporins were evaluated, using detection of ESBL genes as the reference test. These test characteristics are in line with a previous report using the less-expensive cefepime-clavulanate combination disks (The ESBL prevalence varied between 0% and 30% per hospital (All isolates were susceptible to meropenem, imipenem, and tigecycline. endobj Of the ESBL-producing isolates, 40% were MDR, i.e., simultaneously resistant to ciprofloxacin, cotrimoxazole, and tobramycin or gentamicin, versus 3% in the non-ESBL isolates. The … Susceptibility testing was performed by broth microdilution (BMD), except for cefpodoxime (Etest; bioMérieux, Marcy l'Etoile, France), using CLSI and EUCAST breakpoints.

cefotaxime and/or ceftazidime MIC >1 mg/L or an automated system ESBL warning).

Strains of Enterobacteriaceae producing an extended spectrum β-lactamase have become a concern in medical bacteriology as regards both antimicrobial treatment and infection control in hospitals. These tests often need to be refined in order for them to detect an ESBL in some bacterial x���n�F�=���/�nDϝd�0�N�&�fkg�!�bˎvmɕ����=�̅�#���bQ�&�gΜ�M������jv�}����������e�~�|u������|���z��=,V˃����evx��l��8�ί����{ώasv|�2�O|�zxX�n>[d&:ZV �'���M2��M��B�L�aW6eS u�~"�Vac%^F������3��e�M]�uH8@��z����_gK���"8}yr���7��u6�/���g��",� ��R���+U�j@4�t����_HDW;�0tY��p�s>9;�G�O������31u_pn��9v�3�5�!W��Th�Ϯ��L��ӡ��t��i��cѵ@�΁�GxT�>^�������6���"��mY�e �rr�;� YT�;b��LHN0�1�Q�$�m��A�">*����r��ɏo�^��9ݿD����� Srzc! No guidelines have been issued for extended-spectrum beta-lactamase (ESBL) detection in members of the The aims of this study were (i) to develop a phenotypic ESBL detection strategy in To develop a phenotypic ESBL detection strategy, the Vitek 2 advanced expert system (AES) (version 5.01; AST N048 cards) and MIC breakpoints of several indicator cephalosporins were evaluated, using detection of ESBL genes as the reference test. As a confirmatory phenotypic test, the PM/PML Etest (cefepime/cefepime plus clavulanic acid) was evaluated.The test characteristics of the ESBL screening methods based on different cephalosporin MICs and the Vitek 2 AES are shown in Test characteristics of screening methods for ESBL production in 271 It should be noted that a cefepime MIC of >1 mg/liter measured with BMD methodology was 100% sensitive, while a cefepime MIC of >1 mg/liter measured with Vitek 2 had a sensitivity of 54% (The PM/PML Etest was evaluated as a confirmatory test on 124 isolates with a BMD MIC of ceftriaxone of >1 mg/liter and/or a MIC of ceftazidime of >1 mg/liter. Of the 4 ESBL-positive strains involved in clonal dissemination (In conclusion, the results of this study provide a practical and accurate strategy for phenotypic detection of ESBLs in This study was funded by an unrestricted grant from MSD (Whitehouse Station, NJ) and Wyeth Pharmaceuticals (Collegeville, PA).For their help and for kindly providing the isolates, we thank Karola Waar (Izore Center for Infectious Diseases Friesland, Leeuwarden, the Netherlands), Gijs Ruijs (Laboratory of Clinical Microbiology and Infectious Diseases, Isala klinieken, Zwolle, the Netherlands), Fre Sebens (Department of Medical Microbiology and Infection Control, Deventer Ziekenhuis, Deventer, the Netherlands), and Willem Vogels (Martini Hospital Groningen, Groningen, the Netherlands).Thank you for sharing this Journal of Clinical Microbiology article.NOTE: We request your email address only to inform the recipient that it was you who recommended this article, and that it is not junk mail.
