Abstract
A 49-year-old patient with changes in the nails of the hallux for 10 years was diagnosed with onychomycosis. The identity of the causative agent was confirmed as Cladosporium halotolerans from the Cladosporium sphaerospermum species complex using molecular techniques. MALDI-TOF identified the agent as C. sphaerospermum complex species. Overall, species such as onychomycosis agents should attract special attention to avoid mistakes in the identification process while considering a probable contaminant as responsible for the disease. These species deserve attention since there are rare descriptions of them as causes of onychomycosis. It is important to recognize them as causes of disease and not just as a probable contaminant.

Abstract
Malassezia spp in skin microbiome scalp has been implicated in seborrheic dermatitis pathogenesis. Thus, treatment based in antifungal combined to topical keratolitic agents have been indicated as well as oral isotretinoin as it reduces the sebum production, glandular's size and possesses anti-inflammatory properties. This randomized, comparative and therapeutic trial aimed toper form the genotypic identification of Malassezia species before and after low-dose oral isotretinoin or topical antifungal treatments for moderate to severe seborrhea and/or seborrheic dermatitis on scalp. Scales and sebum of the scalp were seeded in the middle of modified Dixon and incubated at 32°C. For genotypic identification polymerase chain reaction primers for the ITS and D1/D2 ribossomal DNA were used and followed by samples sequencing. The procedure was conducted before and after therapeutic and randomized intervention for moderate to severe seborrhea/seborrheic dermatitis on the scalp, including oral isotretinoin, 10 mg, every other day and anti-seborrheic shampoo (piroctone olamine), over six months. The M. globosa and M. restricta were the most frequent species isolated on the scalp before and after both treatments. Other non-Malassezia species were also identified. The Malassezia spp. were maintained in the scalp after both treatments that were equally effective for the control of seborrhea/seborrheic dermatitis clinical signs.

Abstract
The aim of this study was to identify Candida species isolated from
women diagnosed with recurrent vulvovaginal candidiasis (RVVC) and their partners;
and to evaluate the fluconazole (FLZ) susceptibility of the isolates. In a period of
six years, among 172 patients diagnosed with vulvovaginal candidiasis, 13 women that
presented RVVC and their partners were selected for this investigation. The isolates
were obtained using Chromagar Candida medium, the species identification was
performed by phenotypic and molecular methods and FLZ susceptibility was evaluated by
E-test. Among 26 strains we identified 14Candida albicans, six
Candida duobushaemulonii, four Candida glabrata,
and twoCandida tropicalis. Agreement of the isolated species
occurred in 100% of the couples. FLZ low susceptibility was observed for all isolates
of C. duobushaemulonii (minimal inhibitory concentration values from
8-> 64 µg/mL), two C. glabrataisolates were FLZ-resistant and all
C. albicans and C. tropicalis isolates were
FLZ-susceptible. This report emphasises the importance of accurate identification of
the fungal agents by a reliable molecular technique in RVVC episodes besides the
lower antifungal susceptibility profile of this rare pathogen C.
duobushaemulonii to FLZ.

Abstract
Sporotrichosis is a polymorphic disease of humans and animals, which is acquired via traumatic inoculation of Sporothrix propagules into cutaneous or subcutaneous tissue. The etiological agents are in a clinical complex, which includes Sporothrix brasiliensis, Sporothrix schenckii, Sporothrix globosa, and Sporothrix luriei, each of which has specific epidemiological and virulence characteristics. Classical manifestation in humans includes a fixed localized lesion at the site of trauma plus lymphocutaneous sporotrichosis with fungal spreading along the lymphatic channels. Atypical sporotrichosis is a challenge to diagnosis because it can mimic many other dermatological diseases. We report an unusual, itraconazole-resistant cutaneous lesion of sporotrichosis in a 66-year-old Brazilian man. Histopathological examination of the skin revealed vascular and fibroblastic proliferation with chronic granulomatous infiltrate composed of multinucleated giant cells. Sporothrix were isolated from the skin lesion, and phylogenetic analyses confirmed it to be sporotrichosis due to S. globosa, a widespread pathogen. Immunoblotting analysis showed several IgG-reactive molecules in autochthonous preparations of the whole cellular proteins (160, 80, 60, 55, 46, 38, 35, and 30 kDa) and exoantigen (35 and 33 kDa). The patient was first unsuccessfully treated with daily itraconazole, and then successfully treated with potassium iodide.

Abstract
PURPOSE To evaluate the efficacy of topical administration of 0.5% povidone-iodine in experimental Fusarium solani keratitis in rabbits. METHODS Fungal keratitis caused by Fusarium solani was induced in the right eye of 24 New Zealand rabbits. The rabbits were randomly divided into 3 different treatment groups: Group I (povidone-iodine) - treated with topical 0.5% povidone-iodine; Group II (natamycin) - treated with topical 5% natamycin; and Group III (control) - treated with topical saline solution. In all groups the rabbits were treated for three days and then sacrificed. The corneas were excised, macerated and immersed in 10 mL BHI. Culture samples were plated daily on Sabouraud's agar for 7 days, and the number of colony-forming units (CFU) was counted. The rabbits were clinically evaluated during the treatment period. RESULTS The povidone-iodine and natamycin groups demonstrated better efficacy than the control group based on the number of rabbits with no colonies growing. However, there were no statistically significant differences between the three groups when the number of CFU was analyzed (p>0.05). CONCLUSIONS Our study demonstrates important methodological considerations in the use of in vivo animal models for the testing of antifungal agents. Using this sample size and methodology of counting CFU, topical 0.5% povidone-iodine demonstrated no benefit in the treatment of experimental Fusarium solani when compared with topical 5% natamycin.

Abstract
We describe a rare case of a subcutaneous infection by both Phaeoacremonium venezuelense and Plectophomella sp. in a Brazilian male. Sequencing of a beta-tubulin gene fragment allowed us to confirm the identification of the former. However, a similar procedure of sequencing rRNA gene fragments was not useful for the identification of the latter fungus.

Abstract
PURPOSE To determine the mycobiota of the healthy conjunctiva in diabetic individuals, according to diabetes type, age, sex, disease time, type of treatment, and stage of diabetic retinopathy of the individuals. To identify the anemophilus mycobiota in the sampling rooms. METHODS A cross-sectional study was carried out on 803 diabetics who reside in the urban area of São Paulo-SP/Brazil. Sabouraud's dextrose agar culture with chloramphenicol was used for primoisolation, and the key of De Hoog was used to identify filamentous fungi. RESULTS Of the evaluated diabetics, 6.6% (53/803) presented type 1 diabetes and 93.4% (750/803) type 2. The positive cultures for fungi in the conjunctiva of diabetics was 4.2% (34/803), with 1.9% (1/53) in type 1 diabetics and 4.4% (33/740) in type 2 diabetics (p=0.720). With respect to the presence or not of isolated fungi, there was no statistically significant association regarding age (p=0.575), sex (p=0.517), disease time (p=0.633), type of treatment (p=0.422), and diabetic retinopathy stage (p=0.655) of the tested individuals. The identified fungi were all filamentous: Aspergillus spp. represented 59.5% (25/42) of isolations and 47.6% (20/42) of isolated species were Aspergillus niger. Growth of anemophilus fungi occurred in the air of the room and coincidences were observed between the isolated species from the air and those from the conjunctiva. CONCLUSIONS Presence of mycobiota in healthy conjunctivas of diabetics was identified, with no significant association between the greater number of positive fungi isolations and the type of diabetes, age, sex, disease type, type of treatment, and stage of diabetic retinopathy. In the collection rooms, anemophilus mycobiota was identified.

Abstract
We performed a prospective double-blind study to evaluate the correlation between inhibition zones obtained by a disk-diffusion test, using Neo-sensitabs of fluconazole (Rosco Diagnostica), and the MICs generated by the NCCLS macrobroth dilution assay. Eighty clinical isolates, representing 5 of the clinically relevant species of Candida, were tested simultaneously by both methods. A clear inverse correlation was found between the results obtained by both tests (r = -0.69). In addition, there was high degree of agreement between methods in the identification of susceptible isolates. However, the resistance definition by disk-diffusion test had a positive predictive value of only 17%. Our data support the hypothesis that Rosco Fluconazole Neo-sensitabs have potential as a screening test for the identification of Candida isolates susceptible to fluconazole. Resistant isolates should be further investigated by standardized broth procedures.

Abstract
Four cases of human dermatophilosis observed in Rio de Janeiro, Brazil, are reported. Data that suggest nail infection by Dermatophilus congolensis are presented. The clinical spectrum of the disease ranged from an asymptomatic infection to a pustular eruption. Our findings suggest that epidermal Langerhans cells play a role in the pathogenesis of the infection.
