Background-Otitis media (OM) is one of the most common childhood infections in pre-school aged children and a major cause of childhood morbidity. OM also represents the most frequent reason for antibiotic prescription in children. It is also the principal cause of childhood hearing loss in India. Objectives- We aimed to study the microbiological prole and their antimicrobial sensitivity pattern in children of otitis media with ear discharge in the tertiary care center in Lucknow and its application in the empirical treatment of otitis media. Methods: The study was conducted from September 2017 to September 2018 on 150 children attending the ENT OPD and Microbiology Department having ear discharge. Ear discharge samples were taken from 150 children (both male and female). Direct gram staining, KOH microscopy, and susceptibility testing were carried out. Results: Among 150 cases, 10 cases were found to be of ASOM, and 140 of CSOM. Predominant organisms were Staphylococcus species (22.67%), followed by Pseudomonas aeruginosa (22%), Klebsiella pneumoniae (10.7%), and Escherichia coli (10.7%). . Among Staphylococcus aureus,55% were Methicillin sensitive Staphylococcus aureus (MSSA) and 45% were Methicillin-resistant Staphylococcus aureus(MRSA). Only 1 Streptococcus pneumoniae was isolated among 10 ASOM cases. Staphylococcus species were found to be 100% sensitive to linezolid and vancomycin, 80% to amikacin and trimethoprim-sulfamethoxazole, 53% to erythromycin, and 46% to clindamycin and levooxacin. 91% isolates of Pseudomonas spp. were susceptible to piperacillin-tazobactam, 80% to cefepime, amikacin, and tobramycin, and 72% to gentamicin. Conclusion: The study of microbial patterns and their antibiotic sensitivity determines the prevalent bacterial organisms causing otitis media in children in the local area and to start empirical treatment of otitis media and its complications for successful outcome, thus to prevent the emergence of resistant strains.

BACKGROUND Active mucosal chronic otitis media (COM) is a disease of the middle ear cleft associated with inflammation and production of pus. The incidence is high in developing countries. It affects all age groups and both genders. If not properly treated, it can lead to complications. The bacterial isolates and their sensitivity pattern vary from place to place and also over time. Early identification of the microorganisms and their antibiotic sensitivity patterns helps in proper selection of antibiotics and quick recovery in COM patients. METHODS Fifty patients with active mucosal COM were selected for the study. The study was conducted over a period of one year. Ear swab from the deep external auditory canal was collected under strict aseptic precautions from these patients before starting antibiotic treatment. Microorganisms were identified by gram staining, growth on different agar plates, and various biochemical tests. Antibiotic sensitivity was done by the Kirby-Bauer method. RESULTS Majority of the patients were in the age group of 21 - 40 years (42 %) with female preponderance (62 %). All patients had a central perforation in the tympanic membrane (100 %). Bacterial growth was seen in 44 samples (88 %). Two samples (4 %) showed fungal growth. Four samples (8 %) showed no growth even after 48 hours of incubation. Single bacterium was isolated in 41 cases (82 %) whereas 3 samples (6 %) showed more than one bacterial growth. The predominant bacteria were Pseudomonas aeruginosa (50 %) followed by Staphylococcus aureus. The other isolates were coagulase negative staphylococci, enterococci, enterobacter, acinetobacter, and E coli. Pseudomonas showed maximum sensitivity to amikacin, imipenem and piperacillin / tazobactam (100 %). The most effective antibiotics for staphylococcus was vancomycin and linezolid. CONCLUSIONS The most common bacteria isolated in active mucosal COM were pseudomonas followed by Staphylococcus aureus. The most effective antibiotics for pseudomonas was amikacin, imipenem and piperacillin / tazobactam. Staphylococcus showed maximum sensitivity to vancomycin and linezolid.

<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: Antibiotic sensitivity pattern of Neisseria gonorrhoae is changing frequently. Objective: The purpose of the present study was to see the antibiotic sensitivity pattern of Neisseria gonorrhoae isolated from women presented with cervicitis.Methodology: This cross sectional study.carried out in the Department  of Microbiology at Dhaka Medical College, Dhaka from July 2011 to December 2012 for a period of one and half year. All the women presented with or without the clinical features of  cervicitis at child bearing age (15 to 49 yrs) with or without pregnancy were enrolled as study population. Endocervical swabs were collected  for Gram staining, culture, biochemical test from clinically diagnosed  patients of cervicitis for presumptive identification of Neisseria gonorrhoeae. The isolates with presumptive identification were confirmed by rapid carbohydrate utilization test (RCUT), which differentiates  N.gonorrhoeae from other Neisseria. Antimicrobial susceptibility test was done according CLSI guideline. Result: A total 245 females were recruited of which N. gonorrhoeae were detected from 39(15.9%) cases. Among 39 positive cases of gonococcal cervicitis, 19 (48.71%) were detected in the age group of 21-30 years. 56.41% were sensitive and 30.76% were resistant to ceftriaxone. Similarly 51.28% were sensitive and 23.07% were resistant to cefuroxime; 23.07% sensitive, 30.76% moderately sensitive and 46.15% resistant to ciprofloxacin. Conclusion: Gonococcal cervicitis is found in a high frequency rate with a reduced sensitivity to antibiotics especially ciprofloxacin, second and third generation cephalosporins.Bangladesh J Infect Dis 2014;1(1):3-7

ABSTRACT Aim: The emergence of Methicillin-resistant Staphylococcus aureus (MRSA) has posed a serious therapeutic challenge. We report the prevalence and antibiotic susceptibility pattern of MRSA in the hospitals attached to GMC, Amritsar, Punjab. Materials and Methods: The study comprised of 250 coagulase-positive staphylococci (COPS) isolated from a total of 6743 clinical specimens (like pus, blood, urine, high vaginal swab, sputum, etc.) of patients admitted in hospitals attached to Government Medical College, Amritsar from January 2008−February 2009. Routine antibiotic susceptibility testing was performed and interpreted as per standard guidelines. Methicillin resistance was detected using oxacillin and cefoxitin disc diffusion method, oxacillin screen agar method, and minimum inhibitory concentration using broth macrodilution method. Results: A total of 115 (46%) strains were found to be methicillin resistant. Multidrug resistance was observed in 73% MRSA strains. However, no strain was resistant to vancomycin. Conclusion: Regular surveillance of hospital-associated infection and monitoring of antibiotic sensitivity pattern is required to reduce MRSA prevalence.
