Title

Phenotypic Distribution of Serine-and Zinc-Type Carbapenemases Among Clinical Bacterial Isolates in a Tertiary Hospital in Benin, Nigeria

Pages

  3-7

Abstract

IsolatesAbstractBackground: Serine and Zinc type Carbapenemases are distributed in many genera of Bacteria and are typically associated with specific regions or countries. Objectives: This study phenotypically determined the prevalence of serine and Zinc-type Carbapenemases among Gram-negative bacilli recovered from clinical specimens in Benin, Nigeria. Materials and Methods: Totally, 158 consecutive non-duplicate Bacterial Isolates (gram-negative bacilli) recovered from clinical samples were screened for serine and Zinc-type Carbapenemases using the simplified Carbapenemase inactivation (sCIM) and ethylenediaminetetraacetic acid-double-disc synergy test methods. Results: The Isolates recovered from clinical specimens included 126 EnteroBacteriaceae (79. 7%), 7 Acinetobacter spp (3. 7%), and 28oxidase positive gram negative bacilli (17. 7%). Twenty-eight Isolates (17. 7%) out of the 158 tested samples were Carbapenemase positive. There was no significant difference in the prevalence of Serine-and Zinc-type Carbapenemases (P = 0. 0748). However, the prevalence of Zinc-type Carbapenemase was significantly higher in Pseudomonas aeruginosa compared with other Isolates (P = 0. 0028) while that of Serine-type Carbapenemase was not affected by the type of clinical Isolates (P = 0. 7216). Finally, the prevalence of both Serine-and Zinc-type Carbapenemases were not affected (P > 0. 05) by clinical specimens and the source of Isolates (in-patient vs. out-patient) respectively. Conclusion: In general, the prevalence of Zinc-type (12%) Carbapenemases was insignificantly higher than that of Serine-type (5. 7%) Carbapenemases. The measures to reduce infections caused by Carbapenemase-producing organisms (CPOs) are advocated accordingly.
