“…We have identified only 17 cases of Aspergillus otitis from a hospital population over a 25 year period. The majority of cases were unilateral, consistent with previously reported cases of Aspergillus otitis in dogs and humans . In humans bilateral otomycosis is more commonly seen in immunocompromised patients .…”

“…Carpagnano et al often found A. ochraceus in exhaled breath condensate of lung cancer patients (27). In other mammals, it was associated with a case of otomycosis in a dog (45). Here, the three isolates were from different clinical origins (i.e., BAL fluid, ear, and heart valve).…”

A multilocus phylogenetic study was carried out to assess species identity of a set of 34 clinical isolates from Aspergillus section Circumdati from the United States and to determine their in vitro antifungal susceptibility against eight antifungal drugs. The genetic markers used were the internal transcribed spacer (ITS) region, and fragments of the beta-tubulin (BenA), calmodulin (CaM), and RNA polymerase II second largest subunit (RPB2) genes. The drugs tested were amphotericin B, itraconazole, posaconazole, voriconazole, anidulafungin, caspofungin, micafungin, and terbinafine. The most common species sampled was A. westerdijkiae (29.4%), followed by a novel species, which was described here as A. pseudosclerotiorum (23.5%). Other species identified were A. sclerotiorum (17.6%), A. ochraceus (8.8%), A. subramanianii (8.8%), and A. insulicola and A. ochraceopetaliformis, with two isolates (5.9%) of each. The drugs that showed the most potent activity were caspofungin, micafungin, and terbinafine, while amphotericin B showed the least activity.KEYWORDS Aspergillus, Circumdati section, clinical isolates, molecular identification, phenotypic identification S ection Circumdati includes aspergilli with biseriate conidial heads in shades of yellow to ochre, with mostly globose vesicles, and sclerotia variable in shape and color (1-3). It contains 26 species (3), with A. ochraceus being the best known and described as an important producer of many extrolites, including the mycotoxin ochratoxin A (3-5). This metabolite has nephrotoxic, immunosuppressive, teratogenic, and carcinogenic properties (6, 7) and is commonly found in coffee, rice, beverages, and other contaminated foodstuffs (3,8). Several species in this section have been involved in different types of infections, such as onychomycosis, caused by A. insulicola, A. melleus, A. ochraceopetaliformis, A. persii, A. sclerotiorum, and A. westerdijkiae (9-14); otomycosis, caused by A. sclerotiorum (15); skin infection, caused by A. westerdijkiae (12); and pulmonary aspergillosis and osteomyelitis, caused by A. ochraceus (16,17). Moreover, A. ochraceus, A. sclerotiorum, and A. westerdijkiae have been repetitively isolated from clinical specimens of immunocompromised patients, although in such cases their pathogenic role is uncertain (18)(19)(20)(21)(22).There are few data on the in vitro antifungal susceptibility of species within section Circumdati. The azoles, especially itraconazole, appear to have good activity against A.

Objective. To determine the prevalence of dermatological, ear and ophthalmological alterations clinically suspected to be caused by fungi and to analyze their occurrence demographically. Materials and methods. We carried out a retrospective study in a clinic in Bogota for small animals. We reviewed the medical histories of patients who requested medical appointments due to dermatological, ear and ophtalmological alterations in 2009 and 2010. Results. In the assessed period, the prevalence of dermatological alterations in dogs was of 7.8%, 4.2% of ear alterations and of 3.3% of ophtalmological alterations. The main etiological suspects through clinical diagnosis were: dermatophytes with an incidence of 86.9% among dermatological alterations, Malassezia with an 86.5% of incidence in ear alterations, and Candida with 83.3% of incidence in ophtalmological alterations. Statistical analysis of variables showed no association with symptoms or clinically diagnosed etiological agents, but the categorized evaluation showed associations of races and ages with the etiologies through clinical diagnosis. The diagnosis of fungal etiologies was accomplished in most cases by clinical findings and less frequently by skin scrapings and ear cytology; in none of the cases a mycological culture was done. The feline population showed no dermatological, ear or ophtalmological alterations compatible with a fungal etiology. Conclusion. In canines, the prevalence of dermatological alterations clinically compatible with dermatophytes was of 86.9%; ear alterations associated with Malassezia were of 86.5%; and ophtalmological alterations Candida-suspected were 83.3%. Final diagnoses were accomplished with the help of clinical findings without following standard diagnostic methodologies such as cultivation. Key words: canines, felines, dermatophytes, Malassezia, Candida
