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 gramnegative
bacteria and nitrofurantoin for different urine samples of Escherichia coli while
linezolid and glycopeptide antibiotics were the most effective antibiotics in gram-positive
cocci.
