چکیده

Background: Today, bacterial resistance is a public health challenge throughout the world, and infections caused by resistant bacteria are associated with increased morbidity, mortality care costs. The objective of this descriptive study to determine prevalence distribution multi-drug (MDR) clinical isolates at National Hospital Zinder, Niger Republic in 2021.Methodology: We conducted cross-sectional in- out-patients from whose samples’ were isolated bacteriology unit laboratory. Bacteria samples following standard aerobic cultures identified using conventional biochemical test schemes. Antibiotic susceptibility testing (AST) was performed agar disk diffusion technique, categorization into sensitive, intermediate or done according recommendations Antibiogram Committee French Society Microbiology (CA-SFM) 2020 version 1.2. MDR defined as least one antibiotic three more categories, while selected such ESBL double synergy test, MRSA cefoxitin test.Results: Seventy-seven (6.7%) species 1153 processed hospital laboratory between June December 2021, which 65.0% (50/77) members order Enterobacteriales. Escherichia coli represented 40.3% (40/77) bacteria, Staphylococcus aureus 13.0% (10/77) Pseudomonas aeruginosa 11.7% (9/77). overall 44.2% (34/77), including 61.8% (21/34) ESBL-producing Enterobacteriales (ESBL-E), 26.5% (9/34) multi-resistant P. (4/34) MRSA, 67.6% (23/34) outpatients. Resistance rates ciprofloxacin, gentamicin, amikacin imipenem 62.0%, 52.0%, 38.0% 8.0% respectively. 100.0%, 88.9%, 77.8%, 33.3%, 22.2%, 22.2% respectively ceftazidime, ticarcillin, imipenem, levofloxacin, amikacin. S. 50.0%, 40.0%, 10.0%, 0% penicillin G, erythromycin, cefoxitin, tetracycline, fusidic acid, chloramphenicol ESBL-E 47.6%, 85.7% amikacin, ciprofloxacin 75.0%, 50.0% respectively.Conclusion: This reports high mainly ESBL-E, concerning carbapenem. Rational use antibiotics implementation surveillance system for must be implemented limit emergence spread Republic.
 Contexte: Aujourd'hui, la résistance bactérienne est un défi de santé publique dans le monde entier, et les causées par des bactéries résistantes sont associées à une augmentation morbidité, mortalité coûts soins santé. L'objectif cette étude déterminer prévalence isolats cliniques multirésistantes l'Hôpital Zinder,République du en 2021.Méthodologie: Nous avons mené transversale patients hospitalisés ambulatoires dont échantillons ont été isolées l'unité bactériologie laboratoire. Les suite aérobies identifiées l'aide schémas tests biochimiques conventionnels. antibiogrammes réalisés technique sur disque gélose, catégorisation sensibles, intermédiaires ou résistants faite selon recommanda- tions Comité Antibiogramme Société Française Microbiologie La définie comme au moins antibiotique trois catégories plus, tandis que certaines telles BLSE d'un synergie SARM céfoxitine.Résultats: Soixante-dix-sept (6,7%) espèces bactériennes partir traités laboratoire hospitalier entre juin décembre 65,0% appartenaient l'ordre représentait 40,3% isolées, 13,0% 11,7% globale était 44,2% 61,8% d'Enterobacteriales productrices (BLSE-E), 26,5% SARM, avec 67,6% provenant externes. taux ciprofloxacine, gentamicine, l'amikacine l'imipénème étaient respectivement 62,0%, 52,0%, 38,0% 8,0%. 100,0%, 88,9%, 77,8%,33,3%, 22,2% ticarcilline, l'imipénème, lévofloxacine l'amikacine. 50,0%, 40,0%, 10,0%, pénicilline l'érythromycine, céfoxitine, tétracycline, l'acide fusidique chloramphénicol. BLSE-E 47,6%, 85,7% l'amikacine, ciprofloxacine 75,0%, 50,0% gentamicine Conclusion: Cette rapporte élevée MDR, principalement BLSE-E, aux carbapénèmes.
