“…The results of the present study correlate with the study of Yehia et al and Than et al 17,18 In the present study, coagulase negative staphylococcus was seen in 32% cases, followed by Pseudomonas aeruginosa (12%), Staphylococcus aureus (16%), E. coli (11%), Klebsiella (10%) and Proteus species in 8%. Staphylococcus areas are the most common bacterial isolate in a study by Arshad et al and Darko et al 19,20 An attempt was made to evaluate the therapeutic effect of four antifungal agents. In 91% of cases, clinical improvement was observed.…”

Background: The term otomycosis is used to describe fungal infection of ear i.e. external auditory canal, eardrum. This condition appears as a primary infection or develops along with external bacterial infections as a results of antibiotic therapy. This study was designed to determine the clinical symptoms and fungal flora of otomycosis cases.Methods: A total 100 (53% males, 47% females) clinically diagnosed otomycosis cases between 06-70 years were included. The external auditory meatus debris was collected by sterile swabs and sent to the microbial laboratory investigations. Results: Highest prevalence was seen in the age group 21-30 years. Itching in the ear was commonest symptom in 89%, followed by ear ache. Positive fungal growth was seen in 94% cases. Aspergillus was the common isolate in 63% cases, followed by Aspergillus niger with Candida albicans (10%), penicillium in 4% cases and Candida in 3% cases. Coagulase negative Staphylococcus was seen in 32% cases, followed by Pseudomonas aeruginosa (12%), Staphylococcus aureus (16%), E. coli (11%).Conclusions: The genus most commonly involved in otomycosis is Aspergillus followed by Candida. Clinical improvement was seen in 91% of cases and most of the cases responded satisfactorily with topical clotrimazole.

“…Otomycosis is a superficial fungal infection of the ear involving the external auditory canal, auricle and even tympanic membrane (1, 2). The causative agents include a wide spectrum of saprophytes (hyaline and dematiaceous), yeasts and rarely dermatophytes (3–5). Although more than 50 species of fungi, including Penicillium spp., Fusarium spp., Mucoracae, Scopulariopsis spp., Alternaria spp., Malassezia spp., Candida spp.…”

Background: Otomycosis is a superficial infection of the ear caused by a spectrum of various fungal agents and its epidemiology depends on geographical region and climatic condition. The aim of this study was to investigate the causal agents and clinical manifestations of otomycosis at a tertiary referral center in Tehran, Iran. Methods: From Apr 2016 to Jan 2017 a set of 412 subjects with suspicion of external otitis were included. Clinical examination and specimen collection were performed by an otorhinolaryngologist. Subsequently, direct examination and culture were performed on specimens and isolated molds were identified morphologically. Yeast isolates were identified using CHROMagar Candida medium and PCR-RFLP of ribosomal DNA whenever needed. Data were analyzed using SPSS. Results: Otomycosis was confirmed in 117 cases (28.39%) including 64 (54.7%) males and 53 (45.3%) females. Patients were within the age range of 10-75 yr and the highest prevalence was found in the age group of 46-55 yr (30.77%). Pruritus (89.74%) and auditory manipulation and trauma (83.76%) were the predominant symptom and predisposing factor, respectively. Among 133 isolates from 117 patients, Aspergillus niger (n=50, 37.59%) was the most common etiologic agent and Candida glabrata (n=25, 18.8%) was the predominantly isolated yeast. Furthermore, 16 cases of mixed infection were identified and coinfection due to A. niger and C. glabrata (seven cases) was the predominant pattern. Conclusion: Our results revealed the high prevalence of C. glabrata and mixed infections in otomycosis patients. Therefore, mycological examinations should be considered for proper treatment.

“…The fungus is not the actual cause but merely a secondary contaminant in cases of otitis external, therefore otomycosis can be seen in mixed bacterial and fungal infections ( 3 ). The causative agents of otomycosis involve various types of fungi, such as hyaline saprophytic mold, dematiaceous saprophytic mold, yeasts, and, rarely, pathogenic molds like dermatophytes ( 4 - 8 ). It is notable that the most common causative agents of otomycosis are from the genus Aspergillus , particularly Aspergillus niger, which has been established by many studies ( 9 - 12 ), but some authors have collected more than 50 causative fungi species in their studies.…”

Background:Otomycosis is a superficial fungal infection often involves the pinna and external auditory canal. It is a pathologic condition, with Candida and Aspergillus, the most common fungal species. It is common worldwide but more prevalent in tropical and subtropical countriesObjectives:The aim of this study was to determine the etiologic agents and local epidemiologic pattern of otomycosis in northwest Iran.Patients and Methods:A series of 140 patients with clinically symptomatic otomycosis were studied in 21 cities, towns, and villages throughout northwest Iran between 2009 and 2011. Clinical samples were collected by swabs and then assessed by mycological investigation.Results:Otomycosis was diagnosed in 129 cases (92%, 76 male, 53 female) with the highest prevalence of cases occurring in males between 21 - 40 years of age. From an etiological point of view, 116 patients (90%, 21 - 40 years old) were infected by saprophytic mold and 9 patients (7%) were infected by yeast. Three cases (2%) involved dermatophytes, and in one case (1%) the subject was infected with Eurotium (the perfect stage of Aspergillus fumigatus). Aspergillus niger was the most common mold that was isolated, followed by A. flavus, A. fumigatus, Penicillium spp., Fusarium spp., and Rhizopus spp. A total of 2 yeasts belonging to genus Candida, C. albicans and C. tropicalis, were isolated.Conclusions:Our study showed a high prevalence of otomycosis in the northwestern area of Iran. As such, proper diagnosis and treatment by aseptic techniques for this disease is urgently needed.
