The study is conducted to diagnose the aerobic bacterial species causing chronic suppurative otitis media (CSOM), reveal the antibiotic susceptibility pattern and detect some of their virulence factors. Samples were collected during the period from June till December 2018.  From a total of eighty-two patients admitted to Samarra Hospital and outpatient clinics of both genders with different age groups, 82 bacterial culture are recovered using a cotton swab. Identification of bacterial isolates is performed depending on micro and macroscopic cultural characteristics and biochemical tests. Results of the current work show that the highest infection rates are at the age groups >1 to 5 and 11 to 20 years by (20%). Among eight bacterial species isolated in the current study (S. aureus, P. aeruginosa, K.pneumonia, S.epidermidis, E.coli, P.vulgaris, C. freundii, E. Cloacae), S. aureus had scored the highest rate (41%) of the total infections while the lowest rate was scored by E.Cloacae(1%). The antibiotic sensitivity test suggests that almost all isolates were sensitive to ciprofloxacin and meropenem (96% and 94% respectively) while they were resistant to Cefixime. The ability of bacteria is isolated from CSOM to produce biofilm and some virulence factors (gelatinase, hemolysin, DNase, urease) are investigated the virulence factor results revealed that. S. aureus, P.aeruginosa, K. pneumonia had the ability to produce biofilm and S. aureus, P. aeruginosa  have the ability the highest production for the majority of virulence factors.   http://dx.doi.org/10.25130/tjps.24.2019.128

Chronic suppurative otitis media (CSOM) is a prevailing and notorious infection in developing countries causing serious local damage and threatening complications. The purpose of the present study was determine the microbiological profile of isolates from discharge in CSOM. This study was conducted at out-patient department of ENT at Rajshahi Medical College Hospital, Rajshahi from January 2014 to December 2014. Samples were taken from 185 patients (both male and female) in all age groups suffering from chronic suppurative otitis media. Their Gram staining, culture, and biochemical tests were carried out to identify the organisms. It showed the predominance by staphylococcus aereus (29.13%), followed by Pseudomonas Aeruginosa (22.83%), Streptococcus Pyogen (14.96%), E.Coli (9.44%), Proteus Mirabilis (6.29%), Klebsiella Pneumonia ( 4.72%).

AbstractBackground:Otitis media is a more frequent occurrence in children, and the disease may progress from an acute to chronic state if appropriate and timely intervention is not initiated.Methods:A total of 212 children aged 6 months to 10 years were examined and treated for otitis media, in a 13-month hospital-based study.Results:Acute otitis media was diagnosed in 130 (61.3 per cent) of the patients. There were 82 (38.7 per cent) chronic suppurative otitis media cases. The incidence of acute otitis media and chronic suppurative otitis media in the first year of life was 54.6 per cent and 45.1 per cent respectively. Chronic suppurative otitis media patients were assigned to one of three treatment groups. Recovery occurred in 70.4 per cent of amoxicillin-treated patients, in 88.9 per cent of amoxicillin-clavulanic acid treated patients and in 96.4 per cent of culture and antibiotic sensitivity test patients. Relapses were seen only in the amoxicillin (five cases) and amoxicillin-clavulanic acid (two cases) groups.Conclusion:The success rate in patients treated with antibiotics makes this option mandatory for an established diagnosis.

<p class="abstract"><strong>Background:</strong> Chronic suppurative otitis media (CSOM) is an ever growing concern of preventable hearing loss and is a major health concern especially in tropical countries. Lack of cleanliness, overcrowding, poverty, malnutrition and medical ignorance are few of the contributing factors. The microbiological flora is constantly changing due to indiscriminate use of antibiotics with rapid change in the antibiotic sensitivity patterns. Hence, this study was undertaken to determine the epidemiological profile, bacteriological profile and the antibiotic sensitivity pattern which would help in establishing a protocol in management of CSOM patients in the hospital.</p><p class="abstract"><strong>Methods:</strong> A total of 100 patients of CSOM attending the ENT Outpatient Department of The Oxford medical College, Hospital and Research Centre were included in the study.

Background: Cholesteotoma is a benign but destructive lesion leading to ossicular necrosis. Objective: To see the frequency of incus bone erosion on mastoid exploration in chronic suppurative otitis media with middle ear cholesteotoma. Study Design: Cross-sectional descriptive study. Setting: This study was carried out in the Department of ENT Unit-2, Sir Ganga Ram Hospital, Lahore. Duration of Study: Fifteen months months (10th April, 2019 to 9th July, 2020) Sample technique: Non- probability purposive sampling Methods: One hundred and twenty patients were admitted through outpatient department of ENT Unit-2, Sir Ganga Ram Hospital Lahore. Patients were included after fulfilling the inclusion criteria and information was collected on a prescribed proforma. Finally during surgery under general anesthesia, the operative findings were noted to know the incus bone erosion after middle ear cholesteatoma formation in chronic suppurative otitis media. Results: A total number of one hundred and twenty patients of chronic suppurative otitis media with middle ear cholesteatoma were included. Out of which 80 (66.7%) were males and 40 (33.3%) were females(Table 1).The patients shown in table 2 were divided in six age groups (Table 2).Table 3 shows that the procedure of mastoidectomy was performed in 112 patients (93.3%) and modified radial mastoidectomy was performed in 8 patients (6.7%).Incus bone erosion in chronic suppurative otitis media with middle ear cholesteatoma in 102 patients (85%) and 18 patients (15%) have no incus bone erosion (Table 4). Conclusion: Ear discharge was the most common presenting characteristic of chronic suppurative otitis media with cholesteatoma. The majority of the cases had ossicular erosion, with the incus being the most common site of involvement. Males are more likely than females to develop cholesteatoma.

Introduction: Chronic suppurative otitis media (CSOM) is a destructive and persistent disease with irreversible sequel and can proceed to serious intra and / or extra cranial complications. Causative agents of infection include bacteria, fungi and viruses with bacteria being the commonest cause. Hence bacteriological studies of CSOM are important for determining effective antibiotic choice and surveillance of bacterial patterns and their relative sensitivities. Materials and Methods:Total 157 patients having CSOM were included in the study. Ear discharge was processed with standard Microbiological procedures. Results: On aerobic culture Staphylococcus aureus 58 (36.96%) was the most common isolate followed by Pseudomonas aeruginosa 35 (21.21%). Fungal culture yielded 19 (11.2%) isolates. Conclusion: Evaluation of microbiological pattern and antibiotic sensitivity of isolates is necessary to decrease the potential risk of complications of CSOM by early institution of appropriate treatment.
