“…This finding is in agreement with other studies. [27][28][29] The increased resistance to Cephalosporin group is warning sign, as these are potent anti-Psuedomals. Some studies have reported good sensitivity to carbapenems while other studies have reported a higher incidence of carbepenem resistance.…”

2 INTRODUCTIONChronic suppurative otitis media (CSOM) is the most common middle ear infection characterized by recurrent ear discharges or otorrhoea through a tympanic perforation from the middle ear.1 In developed countries the incidence of CSOM has decrease but is higher in developing countries attributed to various factors like because of malnutrition, low socioeconomic society, poor personal hygiene, recurrent upper respiratory tract infection and lack of adequate primary health care facilities.2-4 Inadequate treatment of CSOM may lead to serious intra-cranial and extra-cranial complications like facial nerve paralysis, meningitis, mastoid abscess, deafness, lateral sinus thrombosis and intracranial abscess. 5Although the complication are less common now due to availability of broad spectrum antibiotics, the resistance of the causative organisms is very common. 6 The organisms isolated from CSOM include both aerobic (e.g. Pseudomonas aeruginosa) and anaerobic bacteria (e.g. ABSTRACTBackground: Chronic suppurative otitis media (CSOM) is the most common middle ear infection characterized by recurrent ear discharges or otorrhoea through a tympanic perforation from the middle ear. The organisms isolated from CSOM include both aerobic and anaerobic bacteria. Among the bacteria, Pseudomonas aeruginosa (P. aeruginosa) has been particularly blamed for deep seated and progressive destruction of middle ear and mastoid structures through its toxins and enzymes. The present study was done to determine the prevalence and antibiotic susceptibility of P. aeruginosa isolated from CSOM. Methods: This was a retrospective study conducted in a tertiary care hospital in South India in March 2016. Data was obtained from the microbiology records from January 2014 to January 2016. Patients who had active ear discharge for at least three months were included in the study. P. aeruginosa was identified by colony morphology, pigment production, characteristic musty or earthy odor. The identification was confirmed by motility and standard biochemical tests. Results: A total of 293 cases of CSOM were included in the study. Microbial growth was seen in 248 (84.6%) cases and remaining 45 cases did not show any growth. Among 248 bacterial growth, 87 (35%) were positive for P. aeruginosa. Most common organism was P. aeruginosa followed by Staphylococcus aureus. Highest resistance was seen with Gentamicin and Ofloxacin and least resistance with Imipenem. The increased resistance to Cephalosporin group is warning sign, as these are potent anti-Psuedomals. Conclusions: P. aeruginosa and Staphylococcus aureus were found to be the common cause of CSOM in the present study. P. aeruginosa was resistant to commonly used antimicrobials. There was no resistance seen with Imipenem and only two strains were resistant to Piperacillin+tazobactum. Regular evaluation of the microbiological pattern and antibiogram of isolates will help in decreasing the complications of CSOM.

“…13 Another study involving CSOM also considers Pseudomonas to me the most common causative organism. 14 However, in a study of chronic mastoiditis by Elango et al, Proteus mirabilis was found to be the most common organism isolated which was followed by Pseudomonas aeroginosa, and Staphylococcus aureus. 15 In a study by Xu An-ting et al, coagulase negative Staphylococcus (CONS) was found to be most common organism isolated, both before and after the surgical procedure.…”

Background: This was a comparative microbial study of pre and postoperative mastoidectomy. The aim of the present study was to evaluate various causes responsible for discharging mastoid cavity.Methods: Total of 160 patients of which 100 cases were of preoperative group and 60 cases were postoperative group included in the study. Results: Mono infection was seen in 95% and 86.7% in pre and postoperative cases respectively; where as 5% of preoperative and 13.3% of postoperative cases were diinfections. Pseudomonas (32%) was found in highest number followed by Staphylococcus aureus (16%), Klebsiella spp. (16%), Escherichia coli (15%), Proteus mirabilis (14%), Aspergillus fumigatus (2%), Candida (1%), and Cladosporium (1%) in preoperative cases. In postoperative cases, 46.7% of Pseudomonas spp, followed by 16.5% Staphylococcus, 16.7% Klebsiella spp, 11.7% Proteus mirabilis, 10% Escherichia coli, 8.3% Aspergillus fumigatus and 5% Candida were isolated.Conclusions: Multiple factors were responsible for otorhhoea with significant contribution from the microbes.
