From: Ocular bacterial infections at Quiha Ophthalmic Hospital, Northern Ethiopia: an evaluation according to the risk factors and the antimicrobial susceptibility of bacterial isolates

Type of bacterial isolate Total number of isolates MDRa isolates, N (%)
S. aureus 40 18 (45)
K. pneumoniae 7 4 (57.1)
Other Klebsiella spp. 5 2 (40)
E. coli 15 7 (46.7)
Enterobacter spp. 10 2 (20)
Citrobacter freundii 4 1 (25)
Serratia marcescens 5 1 (20)
P. shigelloides 1 0
Proteus spp. 3 0
Acinetobacter spp. 5 1 (20)
Total 95 36 (37.9)
  1. Notes: a MDR Multi-drug resistant: non-susceptible to 1 agent in 3 antimicrobial categories [43]. Based on this definition, the following antimicrobial categories were considered to determine whether the given isolate is MDR: S. aureus: aminoglycosides, methicillin, SXT, clindamycin, chloramphenicol, macrolides (erythromycin), tetracyclines and fluoroquinolones (ciprofloxacin). Enterobacteriaceae: aminoglycosides, ceftriaxone, fluoroquinolones (ciprofloxacin), SXT, chloramphenicol and tetracyclines. Acinetobacter spp.: aminoglycosides, fluoroquinolones (ciprofloxacin), ceftriaxone, SXT and tetracyclines
