Context nbsp Chronic suppurative otitis media CSOM is a common infection having a high prevalence rate of in India and is one of the leading causes of conductive deafness particularly in the adolescent age group CSOM is frequently associated with multidrug resistant organisms with the ability to form biofilm which is an important virulence factor and results in treatment failure Aims nbsp The main objectives of the study are to identify the spectrum of bacteria associated with CSOM their antibiotic sensitivity pattern and to detect the biofilm formation Methods nbsp This was a prospective cross sectional study at a tertiary care hospital Patients upto the age of having otorrhea for more than weeks and attending the ENT outpatient department were included Samples of pus were collected from the deeper aspect of external auditory meatus and processed using standard techniques for culture and sensitivity Biofilm detection was done Results were compiled and statistically analysed Results nbsp Sixty samples were processed and yielded positive cultures Staphylococcus aureus was the predominant organism followed by Pseudomonas aeruginosa Biofilm formation was seen in per cent of the organisms Biofilms were formed predominantly by Staphylococcus aureus per cent Conclusion nbsp Multidrug resistance has become increasingly common amongst the causative organisms of CSOM this trend being particularly evident among biofilm producers Therefore screening for biofilm formation along with the usual antibiogram needs to be performed as a routine procedure in CSOM to effectively manage the situation by choosing an appropriate modality of treatment nbsp
