Identification of pathogens isolated in acute external otitis cases and evaluation of aminoglycoside and quinolone sensitivity

Abstract

Objective This study aimed to identify pathogens isolated in acute external otitis cases and determine their distribution according to ages and seasons as well as investigate the susceptibility or resistance to the aminoglycoside and quinolone group antibiotics of which topical forms are available. Method A total of 168 patients diagnosed with acute external otitis were evaluated retrospectively. Growing bacteria were identified according to the species by conventional methods. Antibiotic susceptibility status was determined for the growing bacteria. Results The most common bacteria detected were pseudomonas group bacteria (38.7 per cent). Resistance to the amikacin group of antibiotics was found to be the lowest and resistance to the ciprofloxacin group of antibiotics was the highest. Conclusion External auditory canal cultures should be taken simultaneously with empirical treatment. Seasonal effect and age group should be taken into consideration in the choice of treatment and after questioning about chronic exposure to water. Empirical treatment should then be started.

Prevalence and indoor environment risk factors of otitis among preschool children in Urumqi, China

“…Otitis in children is mainly caused by bacteria, of which 69.7% are gram-positive bacteria, 16.7% are gram-negative bacteria, and 13.6% are fungi. 7 Presently, China's medical treatment places otitis under the category of the five organ diseases, so some pediatricians have a vague understanding of it, which leads to a missed diagnosis by physicians, thus concluding that the prevalence of otitis in Chinese children is low and not paid attention to. However, according to the results of this survey, the prevalence of otitis in preschool children in Urumqi was 13.1%, which was higher than the prevalence (11.9%) of otitis among 4618 children in Urumqi investigated by Wang 8 in 2013.…”

Otitis externa

“…Hvor grampositive bakterier som Staphylococcus-og Streptococcus-arter dominerede hos mindre børn (0-10 år), dominerede Pseudomonas, Enterobacterales og svampe i den aeldre aldersgruppe. Grampositive bakterier sås isaer vinter og forår, Enterobacterales isaer om sommeren og Pseudomonas isaer sommer og efterår [8].…”
