title: Microbiological study of external otitis in Rosario City, Argentina.
abstract: Mycological and/or bacteriological studies were performed on 294 samples isolated from the external auditory control (EAC). It was observed that 185 (81.5%) of the mycological analysis were negative while 42 (18.5%) were positive with the following distribution: 22 Candida (9.7%), 15 Aspergillus (6.5%) and five associations of Aspergillus and Candida (2.2%). The bacteriological studies were negative in 52 cases (23.6%) and the frequency of the bacterial agents (75.5%) isolated were as follows: 41 Pseudomonas aeruginosa (18.6%), 24 Proteus mirabilis (10.9%), 24 Staphylococcus aureus (10.9%), and three associations of Ps. aeruginosa and Pr. mirabilis (1.4%). Pseudomonas aeruginosa, which was the most frequent bacterial species isolated, did not present associations with any fungus.
