Abstract

We investigated the microorganisms causing blood culture–negative endocarditis (BCNE) in Morocco. We tested 19 patients with BCNE by serologic methods, molecular methods, or both and identified Bartonella quintana, Staphylococcus aureus, Streptococcus equi, and Streptococcus oralis in 4 patients. These results highlight the role of these zoonotic agents in BCNE in Morocco.

Highlights

  • We investigated the microorganisms causing blood culture–negative endocarditis (BCNE) in Morocco

  • The specimens were referred to the Institut Pasteur du Maroc in Casablanca before being transported to Marseille, France, where diagnostic assays were performed as described by Fournier et al [4]

  • Demographic and clinical features of patients with blood culture–negative endocarditis included in the study.*

Summary

Introduction

We investigated the microorganisms causing blood culture–negative endocarditis (BCNE) in Morocco. Blood culture–negative endocarditis (BCNE) can occur when the patient has previously received antibiotic drugs or in the presence of slow-growing or intracellular microorganisms [1,2]. The aim of this multicenter preliminary study was to investigate the microorganisms causing BCNE in Morocco by using a multimodal strategy.
