Forty-five animals were studied, 20 with and 25 without otitis externa (OE). Cerumen or secretion from external ear canal samples was cultured on modified Mycosel agar and sterile olive oil was added to the surface of the medium before specimen seeding. The isolates were analysed for macro- and micromorphology and identified by catalase tests and on the basis of growth on Tween 20, 40, 60 and 80.<jats:italic>Malassezia<\/jats:italic>spp. were isolated from 15 out of 20 (75%) animals with otitis and from 7 out of 25 (28%) cats without OE; the difference between the two groups was statistically significant (P \u2264 0.05).<jats:italic>Malassezia pachydermatis<\/jats:italic>and<jats:italic>M. sympodialis<\/jats:italic>were isolated from 60% (12\/20) and 40% (8\/20) of cats with otitis, respectively, with no significant difference in the frequency of isolation between the two species. In the microflora of the healthy ear canal<jats:italic>M. pachydermatis<\/jats:italic>was significantly more common (6\/25, 24%) than<jats:italic>M. sympodialis<\/jats:italic>(1\/25, 4%). The present investigation confirms that<jats:italic>M. sympodialis<\/jats:italic>can also act as an aetiological agent of feline OE, and if commercial veterinary laboratories do not use media with added lipids for the isolation of<jats:italic>Malassezia<\/jats:italic>spp., this might lead to false-negative results.<\/jats:p>","DOI":"10.1556\/avet.55.2007.4.6","type":"journal-article","created":{"date-parts":[[2007,11,13]],"date-time":"2007-11-13T21:39:58Z","timestamp":1194989998000},"page":"471-477","source":"Crossref","is-referenced-by-count":33,"title":["Isolation of Malassezia pachydermatis and M. sympodialis from the external ear canal of cats with and without otitis externa"],"prefix":"10.1556","volume":"55","author":[{"given":"C.","family":"Dizotti","sequence":"first","affiliation":[{"name":"1 Paulista University (UNIP) Veterinary Medicine Faculty Rua Agariba 48 S\u00e3o Paulo SP 05053-010 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Selene","family":"Coutinho","sequence":"additional","affiliation":[{"name":"1 Paulista University (UNIP) Veterinary Medicine Faculty Rua Agariba 48 S\u00e3o Paulo SP 05053-010 Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"425","reference":[{"key":"1","doi-asserted-by":"crossref","first-page":"145","DOI":"10.1080\/02681219680000221","article-title":"Isolation of Malassezia sympodialis from feline skin","volume":"34","author":"Bond R.","year":"1996","journal-title":"J.
