Antibiotic resistance profile of Enterococcus spp. strains isolated from the intestinal tract at the Yaounde Military Hospital Laboratory

Multidrug-resistant Enterococci colonizing the intestinal tract of patients are major sources infection as well spread resistance. The present study aims to determine antimicrobial resistance profile Enterococcus species from admitted laboratory Yaounde Military Hospital. was conducted in July November 2020. Stool samples were collected and processed for bacterial isolation susceptibility testing. inoculated onto selective media (Bile Esculin azide agar). isolates obtained identified level genus level: characteristics, Gram staining use API 20 Streptococcus system. Susceptibility testing performed using Kirby-Bauer solid state disk diffusion method. Of 35 analyzed 19 strains isolated, 9 10 non-Enterococci. isolated (25.7%) subjects. faecium (36.9%) followed by faecalis (10.5%), Aerococcus viridans (31.5%), mitis 1 (10.5%) finally 2 (10.5%). tested, 6 (66.6%) resistant Ampicillin, (100%) Gentamycin 4 (44.4%) Amikacin. Other alternative antibiotics treat that may be caused have also shown a high rate vitro: levofloxacin (66.6%), erythromycin 8 (88.8%), tetracycline 7 (77.7%), chloramphenicol (44.4%). (77.7%) vancomycin. Multidrug predominant E. up R7 however multi more pronounced at R3 (94.73%). This reveals faecal colonization multidrug-resistant an increasing prevalence Thus, periodic monitoring antibacterial susceptibilities is recommended detect emerging prevent multi-resistant strains.
