Infectious emergencies are a frequent reason for consultation and admission to an emergency department; bacteriological examinations then represent an essential diagnostic means for these pathologies. The objective of our study was to characterize the bacterial ecology of various infections in the emergency department, and to determine the resistance profile of the main bacteria isolated. We conducted a retrospective study over a 12-month period from June 2021 to June 2022 in the emergency department of the Hassan II University Hospital in FES, including all patients who had undergone bacteriological examinations. we carried out 3557 bacteriological samples, 3124 cytobacteriological examinations of urine, 153 lumbar punctures, 107 pus samples, 88 respiratory samples, 52 punctures and 33 blood cultures were taken; the average age of our patients was 48.4 years with a female predominance (64%). The positivity rate was 18.2%. During our study, 520 bacteria were isolated. Gram-negative bacilli (GNB) predominate at 90%, represented mainly by Enterobacteriaceae (77%), divided essentially into Escherichia coli (60%), Klebsiella pneumoniae (15%) and Proteus mirabilis (2%), followed by non-fermenting Gram-negative bacilli (13%), including 8% Pseudomonas aeruginosa and 5% Acinetobacter baumannii. Gram-positive Cocci represents 10% of bacterial isolates, including 5% Staphylococcus aureus, 4% Enterococcus faecalis and 1% Streptococcus pneumoniae.

The study of antibiotic sensitivity shows that resistance to aminopenicillins was 76%. Resistance to the amoxicillin-clavulanic acid association was encountered in 31% of cases and resistance to 3rd generation cephalosporin in 22% of cases. 12% of Escherichia coli and 9% of Klebsiella pneumoniae produced extended spectrum beta lactamase (ESBL), 6% of Klebsiella pneumoniae were carbapenemase producers. Acinetobacter baumannii was sensitive to colistin alone. All strains of staphylococci aureus were methicillin-sensitive.

The average length of hospitalization for our patients was 4.5 days, the evolution of which was favorable for 89% of patients, and death in 11% of cases.
