Raoultella spp. is increasingly isolated in immunocompromised patients with multiple comorbidities, and there is a growing concern about the presence of multi-drug resistant strains.
Introduction: Raoultella spp. is a gram-negative bacillus with increasing clinical importance due to the development of multi-drug resistance and because it has been reported as a cause of invasive infection. The risk of infection increases if comorbidities present such as diabetes mellitus and malignancies. Methods: Descriptive study of clinical and microbiological characteristics in adult patients with Raoultella spp. isolation, treated at a fourth-level hospital in Bogota, Colombia, between 2015 and 2020. Results: 61 patients with isolation of Raoultella spp., 51 were considered infection and 10, colonization. The associated comorbidities were hypertension (n = 26, 42.6%), heart failure (n = 19, 31.1%) and diabetes mellitus (n = 18, 29.5%). AmpC resistance patterns were found in 10 samples (16.4%) and KPC in 3 (4.9%). Conclusions: Raoultella spp. is of clinical importance due to its isolation in immunocompromised patients with multiple comorbidities and due to the increase in multi-resistant strains.
