Health vigilance concerning Acinetobacter baumannii bacteremia at the mohammed VI university hospital of oujda (morocco): epidemiological profile and antibiotic resistance

The objective of this work is to determine the epidemiological profile of Acinetobacter b aumannii (A.baumannii ) bacteremia in the microbiology laboratory of CHU Mohammed VI of Oujda and its antibiotic resistance rates. This is a retrospective and descriptive study of 27 months from June 24, 2016to September 19, 2018 including all positive blood cultures processed in the microbiology laboratory in accordance with REMIC (reference in medical microbiology)and EUCAST(European Committee on Antimicrobial Susceptibility Testing). Contaminated blood cultures were excluded. As results we collected 863 positive blood cultures, A. baumannii accounted for 7.41% (n = 64). 67% (n =43) of the strains were isolated from patients hospitalized in intensive care (adults, children and newborns). The two main risk factors described in patients with our series were wearing of intravascular device in 55% (n=35) Immunosuppression in 22% n=14). A. baumannii bacteremia was associated with care in 37.5% (n=24). 75% (n=48) of A. baumannii isolates were resistant to carbapenems. No strain of A. baumannii was resistant to colistin. In light of these results strengthening the control and prevention measures for healthcare associated infections would be the most reliable way to limit the spread of A. baumannii in our establishment

Health vigilance concerning bacteremia in neonatology - neonatal intensive care unit at the Mohammed VI University Hospital of Oujda (Morocco): epidemiological profile and antibiotic resistance

The objective of our study was to describe the epidemiological profile of blood culture isolates in the neonatology - neonatal intensive care unit of the Mohammed VI University Hospital of Oujda (Morocco) and to specify the resistance profile of the main germs isolated to antibiotics .This is a retrospective and descriptive study of 21 months from December 14, 2016 to September 14, 2018 and covering all positive blood cultures processed in the microbiology laboratory in accordance with REMIC (reference in medical microbiology) and EUCAST (European Committee on Antimicrobial Susceptibility Testing).contaminated blood cultures were excluded. As results, we collected 275 positive blood cultures. They occurred in the context of intravascular device (IVD) use in 59% (n=162) of cases. The most isolated bacterial groups were coagulase-negative staphylococci (CNS) 41.45 %( n=114), followed by Enterobacteriaceae 32.36 %( n=89).CNS were resistant to all beta-lactams in 57.89 %( n=66), and to glycopeptides in 5.26 %( n=6). Enterobacteriaceae were producers of extended-spectrum betalactamases in 79.77% (n=71) and producers of carbapenemases in 13.48% (n=12) of cases. The alarming increase of enterobacteriaceae isolates and their antibiotic resistance rates should encourage the reinforcement of hygiene measures in our University Hospital
