However, there are no reports regarding species of dermatophytes associated with alpacas and reservoirs of infection.

Airborne dermatophyte propagules concentration in cowsheds as an underestimated reservoir of potential zoonoses.

Aims: Indoor air quality in stables, cowsheds or henhouses has recently become in interest due to the potential risks of zoonotic infections. Cowsheds are commonly known to have high fungal loads, particularly if insufficient attention is paid to the monitoring and control of the indoor microclimate around three elements, that is heating, ventilation and lighting. The aim of this study was to determine the concentrations and spectrum of dermatophyte propagules in the indoor air of cowsheds.

Update on -Black Mold Perceived as Toxigenic and Potentially Pathogenic to Humans.

In nature, there are many species of fungi known to produce various mycotoxins, allergens and volatile organic compounds (VOCs), as well as the commonly known etiological agents of various types of mycoses. So far, none of them have provoked so much emotion among homeowners, builders, conservators, mycologists and clinicians as Stachybotrys chartarum. This species compared to fungi of the genera Fusarium and Aspergillus is not as frequently described to be a micromycete that is toxigenic and hazardous to human and animal health, but interest in it has been growing consistently for three decades.

European Hedgehogs (Erinaceus europaeus L.) as a Reservoir of Dermatophytes in Poland.

The 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.

Cold atmospheric pressure plasma (CAPP) as a new alternative treatment method for onychomycosis caused by Trichophyton verrucosum: in vitro studies.

Purpose: Anthropophilic dermatophytes as etiological factors of onychomycoses are more common than zoophilic fungi. In the case of the latter, reverse zoonoses are possible, which poses a threat to the persistence of dermatophytes in the environment. Nevertheless, without treatment, both types of tinea unguium may lead to complete nail plate destruction and secondary mixed infections with fungi and bacteria.

The technologically advanced methods for dermatophyte detection include molecular methods based on PCR.

In vitro evaluation of photodynamic activity of methylene blue against Trichophyton verrucosum azole-susceptible and -resistant strains.

The intense search for the "Holy Grail" of antifungal therapy can be observed today. The searches are not limited only to discovery of potential antifungal drugs, but also new therapeutic strategies involving the use of chemosensitizers to achieve synergistic effect or physicochemical factors inducing stress conditions in fungal cells. In this study was examined in vitro effectiveness of photodynamic antifungal strategy with methylene blue using a light beam with a wavelength equal to 635 nm toward the Trichophyton verrucosum susceptible and itraconazole- and/or fluconazole-resistant strains.

Therapeutic efficacy of topically used luliconazole vs. terbinafine 1% creams.

Objectives: Dermatomycoses of zoophilic origin, especially those caused by Trichophyton mentagrophytes, often pose considerable therapeutic problems. This is reflected in the growing number of strains of this species with resistance to terbinafine caused by a mutation in the squalene epoxidase (SQLE) gene. Therefore, it is reasonable to look for alternative therapies to the commonly used terbinafine.

Comparative study of multidrug-resistant obtained from different hosts.

The possible transfer of antimicrobial resistance genes between isolates from humans and different animal species, including those not covered by monitoring programs (e.g. pet and wildlife), poses a serious threat to public health.

Genetic Predisposition and its Heredity in the Context of Increased Prevalence of Dermatophytoses.

Dermatophytosis is a widespread disease with high prevalence and a substantial economic burden associated with costs of treatment. The pattern of this infectious disease covers a wide spectrum from exposed individuals without symptoms to those with acutely inflammatory or non-inflammatory, chronic to invasive, and life-threatening symptoms. Moreover, the prevalence of cutaneous fungal infections is not as high as might be expected.

Unusual Penile Prolapse with an Infectious Background Caused by the Burkholderia cepacia Complex in a Stallion.

Penile prolapse is a disease manifested by an inability to retract the penis into the preputial sheath. It is reported in a variety of animal species, especially in young and intact males. However, penile prolapse in horses is commonly caused by trauma, sexual activity, pseudohermaphroditism, or neurological deficits, and less often by an infectious background.

Complementary effect of mechanism of multidrug resistance in Trichophyton mentagrophytes isolated from human dermatophytoses of animal origin.

Background: Dermatophytoses have gained interest worldwide due to the increased resistance to terbinafine and azoles and difficulty in management of these refractory diseases.

Objectives: In this study, we identified and analysed Trichophyton mentagrophytes clinical isolates obtained from humans with infections of animal origin.

Methods: We used quantitative real-time PCR (qRT-PCR) to examine the transcriptional modulation of three MDR genes (PDR1, MDR2 and MDR4) and analysed squalene epoxidase (SQLE) gene sequences from multidrug-resistant Trichophyton mentagrophytes isolates.

Analysis of the occurrence and molecular characteristics of drug-resistant strains of Enterococcus faecalis isolated from the gastrointestinal tract of insectivorous bat species in Poland: A possible essential impact on the spread of drug resistance?

Bats are poorly understood as a reservoir of multidrug-resistant strains; therefore, the aim of this study was to determine molecular characterization of multidrug-resistant Enterococcus strains isolated from bat species from Poland. A multi-stage analysis based on targeted isolation of drug-resistant strains (selective media with tetracycline, chloramphenicol, gentamicin, streptomycin, and vancomycin), determination of the phenotypic profile of drug-susceptibility using the disc diffusion method, and amplification of DNA fragments surrounding rare restriction sites (ADSRRS-fingerprinting) was used for the isolation and differentiation of strains. The applied strategy finally allowed identification of E.

Wildlife omnivores and herbivores as a significant vehicle of multidrug-resistant and pathogenic Escherichia coli strains in environment.

The phenomenon of resistance of Escherichia coli strains in free-living animals has been constantly expanding in recent years. However, the data are still fragmented and, due to the growing threat to public health, there is a constant need to search for and analyse new reservoirs and indicate their role and importance in the circulation of resistance genes in the environment. Therefore, the target group in this study were free-living non-predatory animals as reservoirs of drug-resistant and potentially virulent E.

Wildlife Carnivorous Mammals As a Specific Mirror of Environmental Contamination with Multidrug-Resistant Strains in Poland.

In recent decades, the number of studies on the occurrence of resistant strains in wildlife animals has increased significantly, but data are still fragmentary. The aim of this study was to evaluate drug resistance of strains isolated from wild carnivorous mammals, common in Poland. Selective media with antimicrobials (tetracycline, kanamycin, chloramphenicol, and cefotaxime) were used for isolation.

Dermatophytosis with concurrent Trichophyton verrucosum and T. benhamiae in calves after long-term transport.

Background: Dermatophytosis is a common problem in cattle. The aetiological factors associated with this disease are filamentous fungi with the ability to digest and grow on keratinized substrates. In cattle, and less frequently in other domestic animals and people, the dermatophyte Trichophyton verrucosum is most commonly isolated from skin lesions.

Intrinsic resistance to terbinafine among human and animal isolates of Trichophyton mentagrophytes related to amino acid substitution in the squalene epoxidase.

Background: Dermatomycoses are the most common fungal infections in the world affecting a significant part of the human and animal population. The majority of zoophilic infections in humans are caused by Trichophyton mentagrophytes. Currently, the first-line drug for both oral and topical therapy is terbinafine.

Population differentiation, antifungal susceptibility, and host range of Trichophyton mentagrophytes isolates causing recalcitrant infections in humans and animals.

The major problems in determining the causative factors of the high prevalence of dermatophytoses include the lack of a well-standardized antifungal susceptibility testing method, the low consistency of in vitro and clinical minimal inhibitory concentration values, the high genomic diversity of the population, and the unclear mechanism of pathogenicity. These factors are of particular importance when the disease is recalcitrant and relapses. Herein, we identified and characterized Trichophyton mentagrophytes isolates obtained from therapy-resistant cases in humans and animals.
