Background: Bacterial infections are a significant public health concern, and understanding the bacteriological profile and antibiotic sensitivity patterns of clinical isolates is crucial for effective treatment. This study aimed to investigate the bacteriological profile and antibiotic sensitivity patterns of clinical isolates obtained from patient samples attending a tertiary care hospital in Eastern Uttar Pradesh, India. Materials and Methods: Throughout a certain time, 695 positive clinical isolates were obtained from hospital outpatients as part of a cross-sectional investigation. Conventional bacteriological identification methods such as colony morphology, gram staining, and biochemical assays were used to determine the isolates' identities. As the Clinical and Laboratory Standards Institute (CLSI) recommended, the disc diffusion technique was used to determine antibiotic susceptibility. Following national and international standards, the tested antibiotics represented a broad spectrum of routinely used antibiotics across several classes. Results: The analysis of the bacteriological profile revealed the presence of various bacterial pathogens among the clinical isolates. The most frequently isolated bacteria were 63.0% gram-negative fermenter (GNFB) followed by non-fermenter gram-negative bacteria (FNGNB) 19.0% and Gram Positive cocci 18.0%. Regarding antibiotic sensitivity patterns, the study found variations in the susceptibility profiles of different bacterial species to the tested different classes of antibiotics. Conclusion: This study reveals clinical isolates' bacteriological profile and antibiotic sensitivity patterns. Antibiotic resistance patterns should be monitored regularly to enhance antibiotic selection and patient outcomes. Data can help create local antimicrobial stewardship programs and evidence-based treatment guidelines.
