BACKGROUND: Chronic Suppurative Otitis Media (CSOM) causes hearing impairment and frequently occurred in low-income country where medical care and personal hygiene are poor. Staphylococcus aureus and Pseudomonas aeruginosa are the most common cause of CSOM. We investigated prevalence and antimicrobial susceptibility of S. aureus and P. aeruginosa from tubotympanic CSOM patients in tertiary hospital, Purwokerto, Indonesia in 2016-2017.METHODS: Ear swab specimens were collected from patients with tubotympanic CSOM. S. aureus and P. aeruginosa were isolated and identified by culture, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), and molecular tools. Antimicrobial susceptibility testing was performed using the disk diffusion method.RESULTS: Out of ear swabs from 34 patients with tubotympanic CSOM, P. aeruginosa and S. aureus were identified in 35%patients. No Methicillin-resistant S. aureus (MRSA) strain was found from the ear swabs of the patients with tubotympanic CSOM. Bacterial identification using the MALDI-TOF MS was concordantly with culture and molecular tools. All S. aureus isolates showed full susceptibility to cefoxitin and trimethoprim-sulphamethoxazole. Resistance to tetracycline was common with only 64% of S. aureus strains being susceptible. Meanwhile, all P. aeruginosa strains were susceptible to cefepime, cetazidime, meropenem, gentamicin, and tobramycin.CONCLUSION: S. aureus and P. aeruginosa are found in patients with tubotympanic CSOM and still susceptible to different antibiotic agents. MALDI-TOF MS demonstrate rapid, accurate and robust to detect S. aureus and P. aeruginosa.KEYWORDS: Staphylococcus aureus, Pseudomonas aeruginosa, chronic tubotympanic suppurative otitis media

Medical management of chronic suppurative otitis media without cholesteatoma in children was shown recently to be efficacious. We undertook a prospective study in order to determine 1) the organisms associated with the disease and their sensitivity to various antibiotics and 2) their association with clinical variables. Pseudomonas was isolated from 84% of the patients, enteric gram-negative bacilli from 32%, Staphylococcus aureus from 20%, streptococci from 14%, and Hemophilus influenzae from 15%. Pseudomonas aeruginosa was the sole isolate in 48 of the 128 patients (38%). The sensitivity of P aeruginosa (78 isolates) was 100% (of isolates) to mezlocillin and ciprofloxacin, 99% to tobramycin and ceftazidime, 97% to piperacillin, 94% to gentamicin, and 78% to ceftriaxone. The isolated organisms and their sensitivity to antibiotics were not associated with age, sex, duration of otorrhea, or the presence of granulation tissue or polyps. We believe that our data may contribute to the appropriate choice of antibiotics when nonsurgical management of chronic suppurative otitis media without cholesteatoma is considered.

Objectives: To identify the bacterial pathogens associated with chronic suppurative otitis media and their antimicrobial sensitivity and resistance   Study Design: Cross-sectional survey   Setting: The study was carried out from July 2004-July 2005 at the outpatient clinic of a government tertiary hospital.   Number of subjects: A total of 32 patients (54 ears) with unilateral or bilateral active chronic suppurative otitis media.   Results: Bacterial pathogens of 54 ear discharge samples from CSOM were studied. Among them, 42 (78%) were pure cultures and 9 (16.7%) were mixed, only 3 (5.6%) of the submitted samples had no growth. There were 42 pure isolates, the most common of which was Staphylococcus aureus 21 (50%), followed by Pseudomonas aeruginosa 14 (33.3%). Drug sensitivity pattern of Staphylococcus aureus showed that 61.9% were resistant to Penicillin while more than 90% were sensitive to Aminoglycosides and Clindamycin. Pseudomonas aeruginosa was resistant to penicillin in 64.3% of cases and Ciprofloxacin was active against pseudomonas in 85.7%.   Conclusion: The most common bacterial pathogens from CSOM include Staphylococcus aureus and Pseudomonas aeruginosa. Majority of the isolates of Staphylococcus aureus were resistant to penicillin. Aminoglycosides, macrolides and quinolones were effective against most of the isolates of Staphylococcus aureus.   Keywords: chronic otitis media, perforated tympanic membrane, chronic aural discharge

Microbiology of 102 ears with chronic suppurative otitis media was studied for aerobes, anaerobes, and fungi. Forty-four percent were pure cultures, 33.3% were mixed, and 18.6% had no growth. Seventy-four percent were aerobes, 25% fungi, and only 0.9% anaerobes. Pseudomonas aeruginosa (22.5%) was the most common isolate, followed by Staphylococcus aureus and the Aspergillus species. The possible reasons for low yield of anaerobes and the pathogenic roles of anaerobes and fungi in chronic suppurative otitis media are discussed. It is advocated that in investigating pathogenic organisms in chronic suppurative otitis media, requests should include anaerobes and fungi.

The present study was carried out to determine the aerobic microorganisms involved and their antibiotic sensitivity pattern in patients with Chronic Suppurative Otitis Media (CSOM) and to provide a guideline for empirical antibiotic therapy.Between March 2009 to February 2011, the ear discharge samples submitted at the microbiology laboratory were processed aerobically and all the isolates were included in this study. All organisms were identified morphologically and biochemically by standard laboratory procedures and antibiotic susceptibility pattern was determined by modified Kirby Bauer disc diffusion method as per National Committee for Clinical Laboratory Standard recommendations.Out of a total of 214 samples, microbiological culture was yielded from 202 (94.3%) specimens. Single organism were isolated from 168 (78.5%) of the culture positive specimens, while the remaining 34 (15.9%) had two or more organisms isolated. Pseudomonas aeruginosa 59 (35.1%) was the most common isolate, followed by Staphylococcus aureus 42 (25.0%) including 5 (3%) of the Methicillin Resistant Staphylococcus Aureus (MRSA). Antibiotic sensitivities of Pseudomonas aeruginosa showed that 93.2% isolates were sensitive to tobramycin, whereas, 91.5% isolates were sensitive to ceftazidime and 77.9% to amikacin.Only 50.8% of the isolates of Pseudomonas aeruginosa were sensitive to ciprofloxacin and 25.4% to gentamicin. For Staphylococcus aureus (other than MRSA) 95.2% were sensitive to cloxacillin, 83.3% to gentamicin and 78.5% to erythromycin. Only 07.1% were sensitive to ampicillin and 26.1% to ciprofloxacin.Pseudomonas aeruginosa was the most common isolate followed by Staphylococcus aureus. More than 90% of Pseudomonas and 90% of Staph aureus were sensitive to tobramycin and cloxacillin respectively. Therefore, these two drugs may be included in the formulary to cover the most common aerobic isolates involved in CSOM.Journal of College of Medical Sciences-Nepal, 2011, Vol-7, No-2, 1-8DOI: http://dx.doi.org/10.3126/jcmsn.v7i2.6673

Aspiration of exudate through an open perforation was performed in 183 patients with chronic otitis media. The pus was cultured aerobically and anaerobically. Aerobes only were isolated from 71 patients (39%); 20 patients (11%) had only anaerobes; and 91 patients (50%) had both aerobes and anaerobes. Only 1 specimen had no growth. There were 259 aerobic isolates. Pseudomonas aeruginosa was recovered from 68 patients. Other aerobes commonly recovered included Staphylococcus aureus and Klebsiella pneumoniae. There were 178 anaerobic isolates. Only anaerobic gram-positive cocci were isolated in 20 instances. Sixty-three Bacteroides isolates were recovered, including 12 Bacteroides fragilis group and 21 Bacteroides melaninogenicus.

<p class="abstract"><strong>Background:</strong> The study was conducted to assess the type and frequency of isolation of different microorganisms in uncomplicated chronic suppurative otitis media (CSOM) and their antibiotic sensitivity in our institution.</p><p class="abstract"><strong>Methods:</strong> A total of 88 consecutive patients with unilateral or bilateral active, chronic suppurative otitis media attending outpatient department at DGMAH were included in the study after obtaining an informed consent. There were 55 males (62.5%) and 33 females (37.9%) with age range between 6 months and 76 years. Pus swabs were taken through the perforation site and from the promontory after ear mopping under direct vision.  </p><p><strong>Results:</strong> Children less than 5 years were more affected (23.9%) than older children 5-10 years (13.6%) and 11-15 years (11.45%).
