Multidrug-resistant Enterobacteriaceae are a major public health threat worldwide. These germs are the most redoubtable because they are producers of beta-lactamases and possess other mechanisms of resistance to many antibiotics. The objective of this work is to identify isolated strains of Enterobacteriaceae and to study their antibiotic resistance profiles, thus contributing to the surveillance of antibioresistance. This is a retrospective study over a period of three years (2018-2020) including urine samples taken in the region of Rabat-Salé-Zaire and examined at the laboratory of Epidemic Diseases in National Institute of Hygiene of Rabat. Enterobacteriaceae were the most frequent germs with a predominance of Escherichia coli (68%) followed by Klebsiella pneumoniae (23%). Extended-spectrum beta-lactamase-producing Enterobacteriaceae accounted for 10.5%. The highest resistance was observed with amoxicillin, followed by ticarcillin, cefalotin, trimethoprim/sulfamethoxazole, amoxicillin+clavulanic acid, nalidixic acid and finally ciprofloxacin and norfloxacin. The aminoglycosides and the 2nd and 3rd cephalosporins were the most active molecules. The sensitivity of imipenem and ertapenem was 100%. This study shows the worrying appearance of resistance to the usual antibiotics in uropathogenic enterobacteria. Rational prescription of antibiotics and monitoring of the evolution of bacterial resistance are necessary in each region.

Human brucellosis is an infectious disease, caused by different species of the genus Brucella. It is a mandatory notifiable disease in most countries, including Morocco, and thus requires special vigilance on the part of health agencies. Prevention of this disease is based on surveillance and prevention of risk factors. Its management is based on serological or other diagnostic tests. The National Laboratory of Epidemic Diseases received 17 blood samples of human origin for notified cases of brucellosis in a region of southern Morocco. Biological confirmation of these samples was performed by Rose Bengal test and ELISA IgM test. The results showed a positivity rate of 88% proving the important role of serological tests in the diagnosis of brucellosis. Other rapid and efficient techniques are becoming essential for the confirmation of cases, taking into account the advanced biosafety procedures for these highly infectious pathogens.
