Chronic suppurative otitis media—A bacteriological study

  • 13 Accesses


A total of 146 cases of chronic suppurative otitis media (CSOM), comprising of 77 males and 69 females in different age groups were studied. A total of 132(77.6%) strains of different bacterial species were isolated as single infecting organism(monobacterial). Two or more bacterial species were obtained from 26 cultures revealing polybacterial growth of 15.3%. Out of total 192 isolates, Pseudomonas sp. ranked highest with 438% incidence followed by staphylococcus pyogenes(18.2%), proteus sp.(12%), Klebsiella sp.(7.3%) and Diphtheroides (6.7%). 86.4% of total bacteria put for antibiotic sensitivity tests showed susceptibility towards gentamycin followed by chloramphenicol(31.3%) and Ampicillin(14.8%).
