Summary: This study investigates the incidence of dermatophytosis among rodents referred to a mycology laboratory during 2019-2021. The results show that 37.4% of rodents were affected by dermatophytosis, with rabbits having the highest prevalence. Microsporum canis was the most commonly isolated agent. Female rabbits were more susceptible, while male guinea pigs and hamsters were more likely to be infected with dermatophytosis. Rodents less than 6 months old were more susceptible to dermatophytosis.

Summary: This study evaluated the breed prevalence, lesion distribution, and seasonality of the T. mentagrophytes complex in dogs from the central United States. It also assessed the clinical response to newer systemic antifungal drugs. The results showed a higher incidence of infection in the American Kennel Club Sporting and Terrier groups, with clinical signs being most prevalent in October. Muzzle and head were the most commonly affected areas, and ketoconazole, itraconazole, and terbinafine were identified as effective treatment options.

Summary: Most inflammatory dermatophytoses in humans are caused by zoophilic and geophilic dermatophytes. Knowledge of the epidemiology of these fungi in animals facilitates the prevention of dermatophytosis of animal origin in humans.

Summary: T. mentagrophytes has become the predominant cause of dermatophytosis in India, with a new Indian genotype being isolated. Traditional diagnostic methods are inadequate, necessitating the use of molecular diagnosis. The rapid shift from T. rubrum to T. mentagrophytes is unprecedented in history.

Summary: Deep cutaneous fungal infections, such as deep dermatophytosis, can cause significant morbidity and mortality, particularly in immunocompromised patients. The use of direct microscopy for rapid bedside diagnosis of disseminated deep dermatophytosis has shown promising results. Purulence sampling and direct microscopy can facilitate early diagnosis and prevent disease progression.

Summary: This article reports a case of erythroderma combined with deeper dermal dermatophytosis in a patient with myasthenia gravis. It highlights the increased risk of developing invasive dermatophytic infections or disseminated fungal infections in immunosuppressed patients with long histories of superficial mycoses. Dermatologists should be alert to this condition and promptly treat superficial dermatophytosis.

Summary: A study in Pune, India found that factors contributing to difficult to treat dermatophytosis include past history of the disease, use of topical steroids or keratolytic agents, consultation with non-dermatologists, hyperhidrosis, obesity, positive family history, tight clothing, and chronic diseases. Treatment by dermatologists/ trained physicians and increasing public awareness about tinea could help alleviate the current crisis.

Summary: Dermatophytosis is a superficial infection caused by a group of fungi called dermatophytes. Identification based on gene sequencing is sensitive and reliable, and can replace traditional phenotypic identification methods. This study compared the performance of two methods in the identification of clinical samples in Puducherry, India.

Summary: This study investigated the epidemiology, clinical types, and factors associated with chronicity in patients with chronic dermatophytosis. The findings showed that extensive area of involvement, atopy, diabetes, and long-term use of systemic corticosteroids were associated with chronicity in these patients. Additionally, the most common etiological agent of chronic dermatophytosis in this study was Trichophyton mentagrophytes.

Summary: This study presents clinical characteristics, diagnosis, and treatment approach of Canadian patients with superficial mycosis caused by T. indotineae, an antifungal resistant strain. The lack of treatment guidelines for this new strain highlights the importance of providing practical approach and treatment recommendations for clinicians encountering such cases in Canada.

Summary: This study reports on three cases of Arthroderma (A.) crocatum isolated from human skin in Germany. The characteristics and epidemiology of this geophilic and likely apathogenic dermatophyte are described, emphasizing the importance of a combination of KOH mount, culture, and genetic analysis for clinically meaningful conclusions. The study suggests that the prevalence of A. crocatum may be currently underestimated.

Summary: By comparing different fungi, it was found that Aspergillus fumigatus AR04 had a faster hyphal growth rate at higher temperatures, and could even grow at 49 degrees Celsius. The fungus reached a steady state at a higher dilution rate of 0.7 h(-1) at 40 degrees Celsius compared to other fungi.

Summary: A decade-long outbreak of dermatophytosis due to a terbinafine-resistant novel species has spread to several countries, with investigations into the molecular background of the SQLE gene revealing high resistance levels in certain isolates. Antifungal susceptibility tests on isolates from different countries identified three species and highlighted the limited distribution of high terbinafine resistance.

Summary: Elderly patients with multiple morbidities or medical treatments are more susceptible to fungal infections, particularly from azole-resistant yeasts like Candida glabrata. Factors such as age and denture-wearing influence the distribution of colonizing fungal species in the oral cavity, with non-albicans Candida species being more common in the elderly.

Summary: Indian strains of Trichophyton mentagrophytes with reduced susceptibility to itraconazole were found in Germany as early as 2011, earlier than previously assumed. This variant of the pathogen cannot be phenotypically distinguished from customary strains and requires genetic identification. The variant is anthropophilic and may lead to further dissemination.

Summary: Tinea corporis is a common superficial fungal infection, whereas tinea of the anogenital region is rare and mostly found in tropical countries. A distinctive variant of pubogenital tinea (PT) characterized by deep tissue infiltration and systemic symptoms has been reported, with transmission via sexual contacts hypothesized. In this case report, PT caused by T. quinckeanum experienced a strong inflammatory reaction following successful treatment with itraconazole.
