“…However, the distribution patterns of these pathogens could vary across different regions [20,22,23] , emphasizing the need for localized epidemiological studies. The predominant clinical symptoms identified in this study, including itchiness, deafness, otorrhea, and otalgia, align with the previously described classic otomycosis presentations [24][25][26] . Pruritus, in particular, was experienced by over 90% of patients, consistent with the literature citing pruritus as a hallmark otomycosis symptom [24,27] .…”

Backgrounds:Otomycosis is a common fungal ear infection affecting people worldwide. Cases may be exacerbated by mixed fungal-bacterial infections, especially those involving antibiotic-resistant bacteria. Understanding the microbiological features and antibiotic susceptibility patterns of the pathogens involved is critical for treatment. This study aimed to investigate the prevalence of mixed fungal-bacterial infections in otomycosis cases in Indonesia, to identify the bacterial species involved, and to determine their antibiotic susceptibility patterns. Materials & Methods: In this study, 47 ear swab specimens were collected from 41 clinically-diagnosed otomycosis cases from April to August 2022. The collected samples were processed by culture and microscopy to identify fungal and bacterial isolates. Antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method. Findings: Fungal isolates alone were detected in 80.9% of the specimens, while 19.1% showed mixed fungal-bacterial growth. The most common fungi were Aspergillus (57.1%) and Candida (42.9%) species. Among bacterial isolates, Staphylococcus aureus was the most frequent (observed in 66.7% of mixed cases), followed by Pseudomonas aeruginosa (22.2%). Also, two of the six S. aureus isolates were methicillin-resistant (MRSA). Both P. aeruginosa isolates were extended-spectrum beta-lactamase (ESBL) producers. Conclusion: Many otomycosis cases in this study demonstrated polymicrobial etiology. The emergence of antibiotic-resistant bacteria poses diagnostic and therapeutic challenges to healthcare systems.

Objective: Otomycosis is a common fungal ear infection in tropical and subtropical regions worldwide. This study aimed to perform mycological analysis on fungal debris from the external auditory canals of the patients to study the most common clinical presentation and fungal species distribution in otomycosis. Materials and Methods: Patients who met the inclusion criteria for this cross-sectional study were included and evaluated after providing written informed consent. After obtaining a thorough medical history, ear swabs for culture, sensitivity, and potassium hydroxide were provided. Patients with positive culture results were studied between September 2019 and March 2021. Results: Among 103 cases observed for 18 months in the Department of ENT, Rajarajeswari Medical College, and Hospital, Bengaluru, India, we found that males (56.31%) were more affected than females (43.68%). Itching (67.96%) was the most primary and common symptom that was observed, followed by pain (20.38%), and the most common predisposing factor was the usage of earbuds (26.21%) followed by water in the ear (23.3%) and oil in the ear (16.50%). Unilateral infection was most common (96%), and the left ear was most affected (64.07%). Aspergillus niger was the most common fungal isolate (60.19%), and otomycosis was very common in postmonsoon (October–December) (58.25%). Conclusion: The most frequent fungal isolates in otomycosis are from the Aspergillus and Candida species. The left ear was typically affected by otomycosis, which frequently had a unilateral predominance. The most common clinical symptoms were itching and pain.
