ABSTRACT The expression of the ubiquitin (Ub) gene in dermatophytes was examined for its relation to resistance against the antifungal drug fluconazole. The nucleotide sequences and the deduced amino acid sequences of the Ub gene in Microsporum canis were proven to be 99% similar to those of the Ub gene in Trichophyton mentagrophytes. Expression of mRNA of Ub in M. canisand T. mentagrophytes was enhanced when the fungi were cultured with fluconazole. The antifungal activity of fluconazole against these dermatophytes was increased in the presence of Ub proteasome inhibitor.

The spread of dermatophytosis among animals and humans in the localities of Ukraine in particular in the city of Kharkiv is due to the presence of range of the most susceptible animals. This information mainly concerns dogs and cats that can be affected by dermatophytosis and may be a reservoir of dermatophyte fungus. Particularly important is that domestic dogs and cats represent a significant epidemiological threat to the population. The purpose of the research was to monitor the morbidity of dermatophytosis in domestic dogs and cats in Kharkiv. Diagnostic studies of dermatophytosis morbidity level determination in domestic dogs and cats were performed complexly including the clinical and epizootic data, microscopic and mycological laboratory tests conducted according to generally accepted methods (Kovalenko et al., 2017; Sutton, Fothergill and Rinaldi, 2001). Dermatophytosis was diagnosed among 231 animals in the study of 1,277 domestic dogs kept by the inhabitants of the city of Kharkiv which was in 18.09% of samples. Dermatophytosis was also detected in 615 animals which constitutes 50.25% in the study of 1,124 cats. The cultures of dermatophytosis agent Microsporum canis were isolated from 126 dogs (18.98%) and 110 cats (40.74%). Trichophyton mentagrophytes cultures were isolated from 16 dogs (2.41%) and 16 cats (5.93%). The percentage of isolated cultures of mold and yeast-like fungi in the studies of sick dogs and cats were 38.55% and 22.25% respectively. Obtained results indicate quite high level of the dermatophytosis spreading among domestic dogs and cats in the city of Kharkiv.

Background. Skin infections were the most frequently encountered of all infections and the 4th leading cause of nonfatal disease burden. Topical drugs have been used for the management of skin infections. The growing concern of drug resistance to the topical agents has warned the need for continuous development of novel drug. Essential oils are the best candidate for new drug with different mode of action and target as they are rich in chemical constituents. Objective. To evaluate and develop safe and effective topical antimicrobial formulations from essential oil of Cymbopogon martini. Method. Essential oil was extracted using hydrodistillation aerial part C. martini and topical formulations were prepared in five different semisolid bases. In vitro antimicrobial investigations were performed on essential oil and topical formulations. Skin sensitizations of the formulations were evaluated using guinea pig maximization. Results. The essential oil of C. martini has shown broad-spectrum antimicrobial potency against all tested organisms with MIC value ranging from 0.65 to 10 μg/ml. Absolute inhibitions of growth of fungi were observed against Trichophyton mentagrophytes and Trichophyton rubrum at concentrations above 1% of oil and against Microsporum canis and Trichophyton verrucosum at a concentration of 4% oil. Among topical formulations, the highest antimicrobial activity was recorded in hydrophilic ointment followed by macrogol blend ointment. The antimicrobial activity of oil was higher in fungal pathogen compared to bacteria. Gram positive bacteria were more sensitive than gram negative bacteria. Hydrophilic and macrogol blend ointment containing 5% oil did not produce any skin sensitization on guinea pigs. Conclusion. In conclusion, topical formulations of C. martini essential oil can be alternative topical agents with safe broad-spectrum activity for the treatment of skin disorder. Further studies should focus on shelf life study and clinical study of the product.

Aim. Dermatophytosis is one of the main fungal diseases in humans and animals all over the world.Galla chinensis, a traditional medicine, has various pharmacological effects. The goal of this study was to evaluate the treatment effect ofGalla chinensissolution (GCS) on dermatophytosis-infected dogs (Microsporum canis,Microsporum gypseum, andTrichophyton mentagrophytes, resp.).Methods. The treatment effects of GCS were evaluated by mycological cure rates and clinical score comprised of three indices, including inflammation, hair loss, and lesion scale.Results. The results showed that, in the three models of dermatophytosis, GCS significantly (P<0.05) improved skin lesions and fungal eradication. GCS (10% and 5%) had higher efficacy compared to the positive control (Tujingpi Tincture). The fungal eradication efficacy exceeds 85% after treatment with GCS (10%, 5%, and 2.5%) on day 14.Conclusion. The GCS has antidermatophytosis effect in dogs, which may be a candidate drug for the treatment of dermatophytosis.

Background: Currently, there is a trend towards using natural and ethnopharmacological species with therapeutic potential. This investigation evaluated the antifungal activity of two species in the Ecuadorian Andes, which are used in treating dermatomycosis: Ambrosia arborescens Mill. (Marco) and Aristeguietia glutinosa Lam. (Matico). Methods: We worked with seven concentrations (100 to 700ppm) of Ambrosia arborescens Mill. extract and ten concentrations (0.5 to 5%) of essential oil (EO) of Aristeguietia glutinosa Lam. on Trichophyton mentagrophytes ATCC 9533, Trichophyton rubrum ATCC 28188, Microsporum canis ATCC 36299 and Candida albicans ATCC 10231. The methodology used was a modified version of the Kirby-Bauer method, using diffusion in agar wells. Results: The Tukey test, after the one-way Anova, determined effective concentrations of EO: 5% for Trichophyton mentagrophytes, 4.5% for Trichophyton rubrum, 5% for Microsporum canis and 2% for Candida albicans. In the extracts, the concentration of 700ppm was used for Trichophyton mentagrophytes, Trichophyton rubrum, and 600ppm for Microsporum canis and Candida albicans. Conclusions: The evaluation of the antifungal activity of the Ambrosia arborescens extract showed inhibition in the studied dermatophytes in each one of the planted concentrations (100 to 700ppm). The evaluation of the antifungal activity of Aristeguietia glutinosa EO showed inhibition in the studied dermatophytes in each of the planted concentrations (0.5 to 5%).

European Hedgehog

AbstractThe European hedgehog (Erinaceus europaeus Linnaeus) frequently colonises areas located close to human life in cities, as these are more suitable nest sites offering an abundance of food and allowing avoidance of predators. However, urbanisation has a significant impact on the epidemiology of infectious diseases, including dermatophytoses, the primary source of which are wild animals. In this study, we determined the spectrum of dermatophytes isolated from the European hedgehog and assessed their susceptibility profile to antifungal drugs. Symptomatic and asymptomatic dermatophyte infections were observed in 7.7% and 8% of the 182 examined free-living hedgehogs, respectively. In the pool of the isolated dermatophyte strains, Trichophyton erinacei was dominant (29.9%), followed by Trichophyton mentagrophytes (17.9%), Trichophyton benhamiae (13.4%), Nannizzia gypsea (11.9%), Microsporum canis (10.4%), Nannizzia nana (7.5%), Paraphyton cookei (6.0%), and Nannizzia fulva (3.0%). Susceptibility tests revealed the highest activity of luliconazole and the lowest of activity fluconazole among the azole drugs applied. Although terbinafine generally exhibited high efficacy, two Trichophyton mentagrophytes isolates showed resistance to this drug (MIC = 2 µg/ml) resulting from missense mutations in the SQLE gene corresponding to the amino acid substitution Leu393Phe. Summarising, our study has also revealed that such wildlife animals as hedgehogs can be a reservoir of pathogenic human dermatophytes, including harmful strains resistant to commonly used antifungal drugs.

En una investigación epidemiológica efectuada en la ciudad de Valparaíso y sus alrededores, entre los años 1985-86, se estudió mediante la técnica del tapete la presencia de hongos patógenos y oportunistas en 278 animales domésticos -191 perros y 87 gatos- sin lesiones clínicas aparentes de dermatofitosis en su pelaje.En los 191 perros, un 6,3% presentó dermatófitos zoofíficos (4 Trichophyton mentagrophytes y 8 Microsporum canis) y un 17,3% de dermatofitos geofílicos (2 Microsporum gypseum-fulvum complex, 6 Keratinomyces ajelloi y 24 Trichophyton terrestre). Los 87 gatos presentaron un 18,4% de zoofíficos (2 T. mentogrophytes, 14 M. canis) y un 12,6% de geofí1icos (1 M. gypseum-fulvum complex, 4 K. ajelloi y 4 T. terrestre).La mayor frecuencia de M. canis (16,1% en gatos y solo un 4,2% en perros}, indica que este agente es capaz de sobrevivir en el pelaje sin causar lesiones aparentes y debe considerarse la especie Zoo-antropofílica más común transmisible al hombre en la edad pediátrica.Entre los Onygenales e Hyphomycetes relacionados, la mayoría de los aislamientos corresponde a las especies de chrysosporium (30,9% del total de perros y 50,6% del total de gatos).Entre las especies fúngicas potencialmente patógenas, puede apreciarse una franca predominancia de los géneros Scopulariopsis, Altenaria y Aspergillus en perros y de Scopulariopsis y Alrernaria. en gatos. Phialophora verrucosa y Exophiala jeanselmei, se destacan como hallazgos interesantes

Main Component

Essential oils obtained by hydrodistillation of different parts of Iris persica L. were investigated for the first time by GC-FID and GC-MS; moreover, their antifungal activities were determined. 34, 32, 27, and 17 compounds were identified in the oils from air-dried flowers, leaves, rhizomes and fresh bulbs, respectively, representing ≥ 98% each oil. The major constituents of the flower essential oil were phenylethanol (24.8%) and furfural (13.8%), which, as the main component, constituted also 39.0% and 22.2% of the leaf and rhizome volatile fractions, respectively. Phenylacetaldehyde (37.1%) was the main constituent of the bulb volatile fraction. In in vitro tests, moderate antifungal activity was detected for the oils against strains of the human pathogenic fungal species Candida albicans, Microsporum canis, and Trichophyton mentagrophytes, the plant-fungal pathogen Pyricularia oryzae, and the fungal food contaminant Aspergillus carbonarius,. The highest activity was exhibited by the essential oils from leaves and flowers, suggesting that they could be considered natural antimicrobial agents.
