The Most Predominant Gram Negative Bacteria in a Public Hospital

Aim: The aim of this study was to explore the occurrence of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii bacteria in a hospital in Al-Kharj.

Methodology: The study included the review of antibiogram results to find the number and percentage of these bacteria in 4 years, 2015-2018.

Results: The total number of bacterial cultures in the 4 years was 3327. Most of these cultures were for gram negative bacteria (81.06%). Regarding gram negative bacteria in the 4 years, the most common was Escherichia coli (represents 19.30% of the total bacteria and 23.80% of gram negative bacteria).

Conclusion: It can be concluded that the most prevalent gram negative bacteria were Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumonia. It is important to conduct more researches to know the prevalence of these bacteria, to know their resistance rate to help health care providers to prescribe and dispense antibiotics wisely.
