Study of Bacterial Pathogens and Antibiotic Sensitivity Pattern of Ear Infections in Patients with Chronic Suppurative Otitis Media Attending a Tertiary Care Hospital in Panipat, India

ABSTRACT

Background: Chronic suppurative otitis media (CSOM) is an inflammation of the middle ear irrespective of the etiology or pathogenesis. CSOM is a disease of multiple etiologies and is well known for its persistence and recurrence in spite of treatment. It is renowned for its arrival suffering disease. Aim: This study aims to study the bacterial pathogens and their antibiotic sensitivity pattern of ear infections in patients with chronic otitis media.Materials and Methods:This prospective study was conducted at the Department of ENT and Department of Microbiology, Medical College and Hospital, India, over a period of 1 year from January 2018 to December 2018. A total of 100 patients were included in this study. The ear discharge which is collected with sterile swabs is subjected to Gram’s staining and culture of the causative organism. Antibiotic sensitivity test of cultured bacterial growth is undertaken to know the susceptibility of the causative organism.Results: Of 100 samples, 72 were positive for microbial growth and 28 showed no growth. The most common bacteria causing CSOM was Pseudomonas aeruginosa in 43 (54.43%) of samples followed by Staphylococcus aureus 12 (15.19%), coagulase-negative staphylococci 9 (11.39%), Klebsiella pneumoniae 7 (8.86%), Escherichia coli 4 (5.06%), Proteus vulgaris 2 (2.53%), and Proteus mirabilis and Streptococcus pneumoniae 1 (1.27%) each. Susceptibility test was done for known the best antibiotic agents which can be used as a proper treatment to CSOM infection.Conclusions: In the present study, the most effective antibiotics agents for most of bacterial isolates were gentamicin, ciprofloxacin, amikacin, and chloramphenicol.
