Abstract
RATIONALE Acute promyelocytic leukaemia (APL) is a rare subtype of acute myelogenous leukaemia. With advances in treatment regimens, namely, introduction of all-trans-retinoicacid, outcomes have drastically improved, its side effects should not be ignored. Mycosis fungoides is one of the side effects of all-trans-retinoicacid treatment, but it may also be a clinical manifestation before disease progression. However, it rarely appears and is easily overlooked. This leads to being easily misled during the treatment process, affecting the treatment plan, and resulting in adverse consequences. Therefore, early identification and judgment can not only provide appropriate treatment options, but also prevent and treat further disease progression. PATIENT CONCERNS The patient was hospitalized for pancytopaenia. After completing the examination, the patient was finally diagnosed with acute promyelocytic leukaemia (acute myelogenous leukaemia-M3). We administered tretinoin and arsenous acid. Evaluation of the treatment effect on the 7th day after chemotherapy showed that the bone marrow morphology showed complete remission. After the second course of chemotherapy, the patient developed red miliary macular papules, which gradually worsened. After completing relevant inspections, Considering that the cases was complicated with skin mycosis fungoides, the patient was treated with budesonide ointment and methylprednisolone as chemotherapy. DIAGNOSES Upon examination, the patient was initially diagnosed with acute promyelocytic leukaemia. Evaluation of the treatment effect on the 7th day after chemotherapy showed that the bone marrow morphology showed complete remission. After the second course of chemotherapy, we discovered the patient was diagnosed with skin mycosis fungoides. INTERVENTIONS Systemic chemotherapy is first given when a patient was diagnosed with acute promyelocytic leukaemia. After the patient happened skin mycosis fungoides, We have adjusted the treatment plan and supplemented it with other treatment plans based on the original chemotherapy, After 2 months of treatment, his condition gradually improved. OUTCOMES All-trans-retinoicacid in the treatment of APL must be given attention because mycosis fungoides should not only be distinguished from infectious diseases but also be further assessed with regard to disease progression and metastasis. LESSONS Acute promyelocytic leukemia needs to be treated with arsenic trioxide. All-trans-retinoicacid in the treatment of APL must be given attention mycosis fungoides. Early diagnosis can guide accurate treatment, which is of great help in alleviating the pain of patients and improving the cure rate.

Abstract
Dermatophytosis is a common superficial infection caused by dermatophytes, a group of pathogenic keratinophilic fungi. Apart from invasion against skin barrier, host immune responses to dermatophytes could also lead to pathologic inflammation and tissue damage to some extent. Therefore, it is of great help to understand the pathogenesis of dermatophytes, including fungal virulence factors and anti-pathogen immune responses. This review aims to summarize the recent advances in host-fungal interactions, focusing on the mechanisms of anti-fungal immunity and the relationship between immune deficiency and chronic dermatophytosis, in order to facilitate novel diagnostic and therapeutic approaches to improve the outcomes of these patients.

Abstract
Tinea capitis is an important superficial fungal infection with a global distribution. It mainly affects prepubertal children and is more common in males. Anthropophilic and zoophilic dermatophytes are responsible for most infections. The pathogen spectrum of tinea capitis varies across different regions and changes over time, and is influenced by multiple factors, such as economic development, changes in lifestyle, immigration and animal distribution. This review aimed to clarify the demographic and etiological characteristics of tinea capitis worldwide and determine the common trends of causative pathogens. By mainly analyzing the literature published from 2015 to 2022, we found that the incidence and demographic characteristics of tinea capitis remained generally stable. Zoophilic Microsporum canis, anthropophilic Trichophyton violaceum and Trichophyton tonsurans were the predominant pathogens. The pathogen spectra in different countries changed in different directions. In some countries, the main pathogen shifted to an anthropophilic dermatophyte, such as T. tonsurans, Microsporum audouinii or T. violaceum; in contrast, it shifted to a zoophilic agent, such as M. canis, in some other countries. Dermatologists are advised to continue monitoring the pathogen spectrum and implement preventive measures according to the reported changes.

Abstract
OBJECTIVE The use of ventricular assist devices (VAD) is increasing; however, diagnosis and management of device complications, such as the driveline exit site (DES) being the portal of entry for fungal infection, is not well known. METHOD A systematic review involving searching PubMed (2005 to July 2020) was conducted. The case of a 43-year-old female patient who had a left VAD (LVAD) (HeartMate 3, Abbott, US) is also reported. RESULTS The patient was successfully treated with ketoconazole cream and oral fluconazole for likely superficial DES fungal infections. We included 36 studies that met our inclusion criteria; however, only one was included in our review. In the literature, five cases of DES fungal infection were reported, with Candida being the only fungal pathogen. CONCLUSION LVAD fungal infections are uncommon but can be responsible for high mortality rates, require a prolonged period of treatment, and can present a huge problem when surgical alternatives are not available. However, Candida species are most common. Fungal infections can only produce clear discharge, and so the classic definition of driveline infection based on purulent secretion can vary. Negative skin culture does not exclude the diagnosis of infection of the DES, and so empirical diagnosis may only be clinically based.

Abstract
BACKGROUND Chromoblastomycosis is an uncommon fungal infection of the skin caused by a variety of dematiaceous fungal species that is typically contracted through direct inoculation into the skin. OBJECTIVE To collect and examine data pertaining to the clinical presentation and management of patients with chromoblastomycosis. METHODS Through a retrospective study, a pathology medical record search was performed from January 2004 to December 2020 at a single institution. RESULTS A total of 9 patients were identified. Seven of 9 cases occurred in solid organ transplant recipients. All cases were located on the extremities. Six of 9 cases were clinically suspected to be squamous cell carcinoma. Seven of 9 cases were treated with surgical excision. Six of 9 patients were treated with oral antifungal medication. Four of 9 patients had received combination therapy. Eight of 9 patients had no recurrence of the disease after treatment. CONCLUSION Chromoblastomycosis presents as verrucous papules or nodules and may clinically and histopathologically mimic squamous cell carcinoma. Immunosuppression is likely a risk factor for the development of chromoblastomycosis. This study highlights the importance of clinical awareness of this disease's clinical presentation and prevalence in immunosuppressed patient populations.

Abstract
Purpureocillium lilacinum, widely used as a commercial biocontrol agent for controlling plant-parasitic nematodes, is an emerging opportunistic pathogen in humans and is increasingly reported, especially among immunocompromised patients. We report a classic case of cutaneous mycosis caused by P. lilacinum. A 51-year-old Chinese woman who received tacrolimus and glucocorticoid therapy for 3 years for nephrotic syndrome experienced recurrent papules, pustules, and ulceration on her right ring finger and subcutaneous nodules on her forearm 6 months ago. A lesion biopsy on the right ring finger revealed multiple epithelioid granulomas in the dermis and fat layer containing slender, pigmented fungal hyphae. The fungal culture showed the growth of violet floccose colonies. Lactophenol cotton blue culture stain demonstrated brush-like phialides, with a swollen basal part attached to chains of conidia. Sequencing of the internal transcribed spacer regions of ribosomal DNA, alignment with GenBank, and use of a Basic Local Alignment Search Tool analysis led to the identification of P. lilacinum. Treatment with oral voriconazole was successful.

Abstract
Herein, we report a case of otitis externa caused by Malassezia slooffiae complicated with mastoiditis. A 70-year-old male complained of fever and severe otorrhea from left external auditory canal 2 months after undergoing a craniotomy to remove a hematoma. He had right-sided paralysis and undertook bed rest. Brain computed tomography revealed continuous fluid accumulation in the left mastoid air cells and middle ear from left external auditory canal in addition to leukocytosis and increased C-reactive protein level. The tympanic membrane was severely swelling. These results indicated the presence of otitis media and mastoiditis. Otorrhea culture showed large amounts of M. slooffiae. The administration of liposomal amphotericin B (L-AMB), the irrigation of external auditory canal with normal saline, and the application of topical ketoconazole ointment were started. The administration of L-AMB for 8 weeks and voriconazole, which was switched from L-AMB, for 4 weeks ameliorated his infection and he was transferred to another hospital to receive rehabilitation. From these results and his clinical course, the diagnosis of otitis externa caused by Malassezia slooffiae complicated with mastoiditis was made. And the possibility of the contamination by M. slooffiae was very low. Clinicians should be aware that M.slooffiae can provoke otological infections since M. slooffiae is the most common Malassezia sp. in external auditory canal.

Abstract
BACKGROUND The prevalence of superficial fungal infections in India is believed to have increased substantially in the past decade. We evaluated the treatment outcomes and risk factors associated with clinical response to a treatment course of itraconazole for the management of dermatomycosis in India. METHODS In this real-world, prospective pilot study (August 2019 to March 2020), adult participants (18-60 years), diagnosed with T. cruris or T. corporis, received itraconazole 200 mg/day (any formulation) orally for 7 days, and were followed for an additional 7 days. RESULTS The study was terminated early due to the COVID-19 pandemic. Of 40 enrolled participants (mean [SD] age, 35.5 [12.73] years; {62.5%}] male; 37 received itraconazole and 20 (50%) completed the study. The median (range) Clinical Evaluation Tool Signs and Symptoms total score at baseline was 5.5 (2-10). Clinical response of "healed" or "markedly improved" based on the Investigator Global Evaluation Tool at day 7 (primary objective) was 42.9% (12/28; 95% CI: 24.53%, 61.19%). Itraconazole minimum inhibitory concentration for identified microorganisms, T. mentagrophytes species complex (91.7%) and T. rubrum (8.3%), was within the susceptibility range (0.015-0.25 mcg/mL). At day 14, 8/13 (61.5%) participants achieved a mycological response, 2/13 participants (15.4%) had a mycological failure and 90% showed a clinical response. CONCLUSION COVID-19 pandemic affected patient recruitment and follow-up, so the findings call for a careful interpretation. Nevertheless, this real-world study reconfirmed the clinical efficacy and microbial susceptibility to itraconazole for the fungi causing dermatophytosis in India. TRIAL REGISTRATION Trial registration number: Clinicaltrials.gov NCT03923010.

Abstract
Sporotrichosis is a subcutaneous mycosis with a global distribution, also known as "rose gardener's disease". Brazil is experiencing a rapid spread of the zoonotic transmission of of Sporothrix brasiliensis, the main etiological agent of this disease in this country, affecting domestic felines. Cost-effective interventions need to be developed to control this emergent public health problem. To allow for the comparison of alternative control strategies, we propose in this paper, a mathematical model representing the transmission of S. brasiliensis among cats, stratified by age and sex. Analytical properties of the model are derived and simulations show possible strategies for reducing the endemic levels of the disease in the cat population, with a positive impact on human health. The scenarios included mass treatment of infected cats and mass implementation of contact reduction practices, such as neutering. The results indicate that mass treatment can reduce substantially the disease prevalence, and this effect is potentialized when combined with neutering or other contact-reduction interventions. On the other hand, contact-reduction methods alone are not sufficient to reduce prevalence.

Abstract
INTRODUCTION Dermatophytosis is a superficial cutaneous mycosis and is steadily progressing to epidemic proportions in India. Various factors such as steroid overuse and misuse are currently making its treatment challenging. The study examines various sociodemographic characteristics, clinical factors, and steroid abuse in patients with dermatophytosis and also assess their quality of life (QOL). METHODS A hospital‑based cross‑sectional study was carried out for a period of 1 year among adult patients with dermatophytosis after obtaining informed written consent. Sociodemographic and clinical details were recorded, and QOL was assessed with the Dermatology Life Quality Index (DLQI) questionnaire. RESULTS Among 550 patients analyzed, the most common dermatophytosis was tinea (n = 408/550, 74.18%), dominated by tinea cruris and tinea corporis. Steroid abuse was frequent (n = 511/550, 92.90%), the most common being clobetasol propionate (n = 26/52, 50%). Hypopigmentation and atrophy were the most common side effects (53.52%). The mean DLQI was 14.44 ± 7.29 in males and 15.78 ± 6.26 in females. DLQI scores were statistically influenced (p < .05) by steroid abuse, low socioeconomic status, young adult status, widespread tinea, and poor hygiene. CONCLUSION Dermatophytosis was found to have a significant adverse impact on QOL. As seen in this study, the widespread abuse of steroids may be a leading cause of the emergence of recalcitrant tinea in India.

Abstract
Deep cutaneous fungal infections including deep dermatophytosis are responsible for significant morbidity and mortality, especially in immunocompromised patients. Variable and longer turnaround time on tissue culture results delay diagnosis. We sought to seek the fast bedside diagnosis for disseminated deep dermatophytosis by direct microscopy using a blunt scalpel or needle aspiration before biopsy. This is a 6-year retrospective review of patients with a diagnosis of disseminated deep dermatophytosis seen at a single tertiary care institution. Trichophyton rubrum was isolated in four patients, and T. mentagrophyte complex in one patient. All the dermatophyte isolates can grow at 37 °C. Microscopy of purulence sampling from intact nodules demonstrated abundant septate hyphae, and also isolation from purulence was concordance with skin tissue culture. Ultrasound-guided sampling from non-eroded can yield purulence, and direct microscopy of purulence may facilitate rapid diagnosis of deep dermatophytosis and serve to prevent disease progression and dissemination.

Abstract
Dermatophytosis is a common and highly contagious zoonotic skin disease in companion animals. This disease is a major concern in geographical areas that contain large numbers of stray animal populations. Numerous surveys on dermatophytosis among stray animal populations worldwide range between 27% to 50%. In recent years, the US territory of Puerto Rico was impacted by several natural disasters such as hurricanes, which has led to a large increase of abandonment cases and an increase in the stray animal population. Due to this, large low-cost spay/neuter clinics and trap-neuter-release programs have become a more common practice on the island. During these events, veterinary staff are exposed to multiple animals with no health history, and therefore, zoonotic diseases are of concern. The aim of this study was to provide information regarding the presence of dermatophyte species in symptomatic and asymptomatic stray dogs and cats in a region of Puerto Rico. Hair samples were collected from 99 stray animals with and without dermatological clinical signs. The hair samples were cultured on plates containing rapid sporulation medium and dermatophyte test medium. All cultures were evaluated microscopically to confirm the presence of dermatophytes. Then, all dermatophytes were further evaluated with MALDI-TOF MS to compare both diagnostic tests. A total of 19 animals (19%) were positive for dermatophyte growth. Of these animals, 18/19 were infected with M. canis and 1/19 with Trichophyton spp. Animals with clinical lesions were positive only 13.5% of the time compared to asymptomatic animals, who were positive in 36% of the sample population. All 19 dermatophytes (100%) diagnosed with microscopic evaluation were confirmed with MALDI-TOF MS. Our results indicate that there is a prevalence of 19% of dermatophytosis among the stray dog and cat population of the southeastern coast of the island.

Abstract
Cryptococcosis is a rare opportunistic infection with morphologically diverse cutaneous presentations. Primary infection typically occurs in the lungs with subsequent hematogenous dissemination to other organ systems, especially in immunocompromised patients. Herein, we report a woman in her 70's who presented with pruritic, umbilicated papulonodules of the bilateral upper and lower extremities present for many weeks. She was diagnosed with disseminated Cryptococcus and subsequently evaluated for potential pulmonary and meningeal disease involvement. She died as a result of multiple medical comorbidities.

Abstract
The aim of this study was to establish an ex vivo model for dermatophyte biofilm growth, using hair from dogs and cats. Strains of Microsporum canis, M. gypseum, Trichophyton mentagrophytes and T. tonsurans were assessed for in vitro and ex vivo biofilm production. All T. mentagrophytes and T. tonsurans isolates and 8/12 M. canis and 1/7 M. gypseum isolates formed biofilms in vitro, while all tested isolates presented biofilm growth on ex vivo models. T. mentagrophytes and M. canis formed more homogeneous and better-structured biofilms with greater biomass production on cat hair but T. tonsurans formed more biofilm on dog hair. Confocal and scanning electron microscopy demonstrated fungal hyphae colonizing and perforating the hair shaft, abundant fungal conidia, biofilm extracellular matrix and biofilm water channels. The present study demonstrated an ex vivo model for the performance of studies on biofilm formation by dermatophytes, using dog and cat hair.

Abstract
A new report in this issue of Journal of Investigative Dermatology reveals a role for IL-17 and IFN-gamma, signature cytokines of T-helper 17 and T-helper 1 cells, in immunity to Trichophyton benhamiae (Heinen et al., 2018). While there have been many recent advances in understanding host defenses against common fungi, this work illuminates not only adaptive immunity, but also innate immune responses to dermatophytosis.

Abstract
CONTEXT Commiphora molmol Engl (Burseraceae) or myrrh has been traditionally used for the treatment of skin fungal infections. OBJECTIVE This study evaluates the antifungal activity of myrrh ethanol extract and essential oil against skin dermatophytes. MATERIALS AND METHODS The antifungal evaluations were performed by the food poisoning technique (250 ppm) and micro-broth dilution assay (800-6.25 µg/mL) against Trichophyton rubrum, T. mentagrophytes, Microsporum canis, M. gypseum, and T. verrucosum. The chemical composition of myrrh oil and ethanol extract was analyzed by GC and GC-MS. RESULTS Furanoeudesma 1,3-diene and menthofuran were the main components of myrrh oil, while 2-tert-butyl-1,4-naphthoquinone, benzenemethanol,3-methoxy-α-phenyl, and curzerene were the main components of myrrh ethanol extract. The inhibitory effect of myrrh oil and ethanol extract against dermatophytes were 43.1-61.6% and 12.5-27.5%, respectively. The MIC and MFC values of myrrh oil were 25-100 and 25-200 µg/mL while these amounts for ethanol extract were 25-400 and 25-400 µg/mL, respectively. Therefore, myrrh oil had higher antifungal activity than that of the ethanol extract. Both extracts showed good anti-elastase activity. CONCLUSION The results of our investigation confirmed the traditional uses of C. molmol as a poultice for the treatment of cutaneous fungal infections.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ethnobotanical reports on more than 100 southern African medicinal plants with dermatological relevance have been highlighted, yet there is still limited scientific data to support claims for their antimicrobial effectiveness against skin pathogens. Guided by ethnobotanical data, this paper explores the antimicrobial efficacies of southern African medicinal plants used to treat skin ailments. AIM OF THE STUDY To investigate the antimicrobial properties of southern African medicinal plants against dermatologically relevant pathogens. The study also aimed at providing a scientific rationale for the traditional use of plant combinations to treat skin diseases and the isolation of the bio-active compound from the most active species, Aristea ecklonii (Iridaceae). MATERIALS AND METHODS Organic and aqueous extracts (132) were prepared from 47 plant species and screened for antimicrobial properties against dermatologically relevant pathogens using the micro-titre plate dilution method. Four different plant combinations were investigated for interactive properties and the sum of the fractional inhibitory concentration (ƩFIC) calculated. Isobolograms were used to further investigate the antimicrobial interactive properties of Pentanisia prunelloides combined with Elephantorrhiza elephantina at varied ratios. A bioactivity-guided fractionation process was adopted to fractionate the organic leaf extract of Aristea ecklonii. RESULTS Plants demonstrating notable broad-spectrum activities (MIC values ≤1.00mg/ml) against the tested pathogens included extracts from Aristea ecklonii, Chenopodium ambrosioides, Diospyros mespiliformis, Elephantorrhiza elephantina, Eucalyptus camaldulensis, Gunnera perpensa, Harpephyllum caffrum, Hypericum perforatum, Melianthus comosus, Terminalia sericea and Warburgia salutaris. The organic extract of Elephantorrhiza elephantina, a plant reportedly used to treat acne vulgaris, demonstrated noteworthy antimicrobial activity (MIC value of 0.05mg/ml) against Propionibacterium acnes. Similarly, Diospyros mespiliformis reported for its traditional use to treat ringworm, also displayed noteworthy antimicrobial activity against Trichophyton mentagrophytes (MIC 0.10mg/ml) and Microsporum canis (MIC 0.50mg/ml). The aqueous root extracts of Pentanisia prunelloides combined (1:1) with Elephantorrhiza elephantina displayed synergistic interactions (ƩFIC values 0.31-0.38) against Staphylococcus aureus, gentamycin-methicillin resistant Staphylococcus aureus, Staphylococcus epidermidis and Candida albicans. Fractionation of Aristea ecklonii resulted in the isolation of the known bio-active compound, plumbagin, displaying noteworthy antimicrobial activity (MIC range between 2.00μg/ml and 16.00μg/ml). CONCLUSION Most of the plant extracts demonstrated pathogen specific antimicrobial effects with a few exhibiting broad-spectrum activities. Positive antimicrobial effects noted for plants such as Elephantorrhiza elephantina and Diospyros mespiliformis used for acne vulgaris and ringworm infections, respectively, give some validation to their reported traditiona l uses. Synergistic interactions noted for Pentanisia prunelloides combined with Elephantorrhiza elephantina validate an enhanced antimicrobial effect when used in combination. Noteworthy antimicrobial activities (MIC range between 2.00μg/ml and 16.00μg/ml) were observed for plumbagin isolated from Aristea ecklonii.

Abstract
CONTEXT Andrographis paniculata Nees. (Acanthaceae) is an annual herbaceous plant widely cultivated in southern Asia, China, and Europe. It is used in the treatment of skin infections in India, China, and Malaysia by folk medicine practitioners. OBJECTIVE Antifungal activity of the whole plant extracts and isolation of active principles from A. paniculata were investigated. MATERIALS AND METHODS Dichloromethane (DCM) and methanol (MEOH) extracts of A. paniculata whole plant were screened for their antifungal potential using broth microdilution method in vitro against seven pathogenic fungal species responsible for skin infections. Active principles were detected through bioguided assays and isolated using chromatography techniques. Structures of compounds were elucidated through spectroscopy techniques and comparisons were made with previously reported data for similar compounds. RESULTS DCM extract revealed lowest minimum inhibitory concentration (MIC) value (100 μg/mL) against Microsporum canis, Candida albicans, and Candida tropicalis, whereas MEOH extract revealed lowest MIC (150 µg/mL) against C. tropicalis and Aspergillus niger. DCM extract showed lowest minimum fungicidal concentration (MFC) value (250 µg/mL) against M. canis, C. albicans, C. tropicalis and A. niger, whereas MEOH extract showed lowest MFC (250 µg/mL) against Trichophyton mentagrophytes, Trichophyton rubrum, M. canis, C. albicans, C. tropicalis and A. niger. Bioassay guided isolation from DCM and MEOH extract afforded 3-O-β-d-glucosyl-14-deoxyandrographiside, 14-deoxyandrographolide, and 14-deoxy-11,12-didehydroandrographolide as antifungal compounds. The lowest MIC (50 µg/mL) and MFC (50 µg/mL) was exerted by 14-deoxyandrographolide on M. canis. DISCUSSION AND CONCLUSION This is first report on the isolation of antifungal substances through bioassay-guided assay from A. paniculata. Our finding justifies the use of A. paniculata in folk medicines for the treatment of fungal skin infections.

Abstract
Seborrheic dermatitis is a chronic relapsing inflammatory skin disorder clinically characterized by scaling and poorly defined erythematous patches. The prevalence of adult seborrheic dermatitis is estimated at 5%. Although the exact cause of seborrheic dermatitis has yet to be understood, Malassezia yeasts, hormones (androgens), sebum levels and immune response are known to play important roles in its development. Additional factors including drugs, winter temperatures and stress may exacerbate seborrheic dermatitis. A variety of treatment modalities are available, including antifungal agents, topical low-potency steroids and calcineurin inhibitors (immunomodulators). This review summarizes current knowledge on the etiopathogenesis and therapy of adult seborrheic dermatitis.

Abstract
Four fungal species including two dermatophytes and two saprophytes were isolated from sewage sludge samples at Basrah (Iraq) they were tested for their degradative ability towards three types of keratin substrates (human hair, chicken feathers and wool). The rate of keratin degradation was expressed as weight loss over three weeks of incubation using a liquid culture medium. Human hair had the highest degradation rate by colonization of Chrysosporium pannicola and Microsporum gypseum at a rate of 62% and 48% respectively. Chicken feathers were highly degraded by Aspergillus flavus (32%) while wool degradation was highest by C. pannicola (45.5%) and Trichophyton mentagrophytes var. erinacei (38%). There was a significant difference (p < 0.001) in keratin substrate degradation rates by the examined fungi. Keratinase activity was highest for C. pannicola and M. gypseum in the culture medium baited with human hair. Aspergillus flavus revealed the highest activity of this enzyme in cultures amended with chicken feathers while T mentagrophytes var. erinacei showed highest keratinase activity in cultures with wool substrate. The amount of protein released into the culture medium varied among the tested fungi. The medium's alkalinity increased over incubation time from 6.5 to 7.8. Microscopic examination showed maceration of the keratin substrates by the fungi.

Abstract
The keratinolytic activity of five species of the dermatophytes which include Trichophyton rubrum, T. mentagrophytes, T. tonsurans, Microsporum audouinii and M. gypseum isolated from school children were tested using human hair as the substrate. M. gypseum was found to possess the highest keratinolytic activity with a net value of released protein being 78.8 ug/ml after five weeks of incubation. Also the net value of released protein for T. tonsurans, T. rubrum, T. mentagrophytes and M. audouinii were 55.5 ug/ml, 52.5 ug/ml, 43.8 ug/ml and 26.3 ug/\ml respectively. Only T. mentagrophytes and M. gypseum were able to cause structural damage in form of perforations on the hair shaft. Also during the degradation of the hair, the pH of the basal medium for each dermatophyte increased. The increase in pH was highest in the medium with M. gypseum but lowest in that of M. audouinii.

Abstract
Hungarian data of 36 zoonotic diseases are summarized. These illnesses cause problems not only for health, public health and veterinary health services but for the society and their importance has increased. Changing character of an old pathogen (Salmonella enteritidis PT4) resulted in new epidemiological situation. The number of cases of food-borne zoonotic diseases has rapidly grown. The number of pets has elevated and in consequence the possibility of an infection of owners, breaders, sellers and other persons has also grown. Growing number of HIV positive patients as well as ill persons treated with immunosuppressive drugs increases the importance of opportunistic zoonotic pathogens (Cryptosporidium, Toxoplasma). The most effective and less expensive way to prevent an exposed population is the active immunization (BCG, tetanus, tick-borne encephalitis). Active immunization of animals can also reduce probability of human infections and economic losses (leptospirosis, rabies). In special cases it is advised to perform eradication programmes to get pathogenic-free domestic animals (brucellosis, bovine tuberculosis, salmonellosis, campylobacteriosis). Permanent surveillance is obligatory to recognize changing nature of pathogens, alteration of epidemiological situation and to identify areas for further research. Continuous education of population in general and special teaching of risky groups are very important for an effective prevention.
