Gentamicin-resistant Pseudomonas aeruginosa corneal ulcers

Area of Science:

• Ophthalmology
• Microbiology
• Infectious Diseases

Background:

• Pseudomonas aeruginosa is a common cause of bacterial keratitis.
• Gentamicin sulfate has been a standard treatment for P. aeruginosa infections.

Observation:

• Six cases of ulcerative keratitis caused by Pseudomonas aeruginosa were studied.
• Antibiotic sensitivity testing was performed for each case.

Findings:

• The study found P. aeruginosa isolates resistant to gentamicin sulfate.
• Sensitivity to other aminoglycosides, including tobramycin and amikacin, was observed.
• Community-acquired infections were the source in four of the six cases.

Implications:

• This highlights the emergence of aminoglycoside resistance in P. aeruginosa keratitis.
• Treatment strategies may need to be reconsidered in light of rising resistance.
• Further surveillance of antibiotic resistance patterns is crucial for effective clinical management.
