Abstract
Background: The aim of this study was to demonstrate various bacteria can be retrieved from clinical samples that can be collected from IPD and OPD patients of the hospital with their antibiotic sensitivity pattern.
Materials and Methods: A total of 232 samples were retrieved in different samples from urine, blood, pus and fluids and respiratory tract. The samples were first identified by a standard biochemical method and then by antibiotic susceptibility testing.
Results: Majority of bacterial isolates were recovered in clinical samples collected from IPD (66.38%). Escherichia coli (34.05%) were mainly isolated in our study. Escherichia coli (59.01%) was the prevalent bacteria in urine samples and was highly sensitive to colistin (100%) and least sensitive to ampicillin (08.33%). Coagulase negative staphylococci (45.24%), were the predominant bacteria in blood samples and maximally sensitive to linezolid (89.47%) while all isolates were resistant to penicillin. Staphylococcus aureus (25.64%) was the predominant bacteria in pus and fluids samples and was maximally sensitive to linezolid while half the isolates were methicillin-resistant staphylococcus aureus (MRSA). Acinetobacter baumannii (44.83%) was the predominant bacteria in respiratory samples and was maximally sensitive to colistin (100.00%) while all isolates were resistant to carbapenems.
Conclusion: Our study shows that Escherichia coli was a predominant type of bacterial isolate in clinical samples and was the majorly bacteria identified in urine samples. The most effective antibiotics in our study found was colistin and carbapenems for gram-negative bacteria and nitrofurantoin for different urine samples of Escherichia coli while linezolid and glycopeptide antibiotics were the most effective antibiotics in gram-positive cocci.
