According to epidemiological, clinical and mycological criteria, it has long been admitted that the Trichophyton mentagrophytes species includes two varieties: a zoophilic variety (var. mentagrophytes) and an anthropophilic variety (var. interdigitale) that involve the upper and the lower part of the body, respectively. The further application of molecular techniques to the characterization of dermatophyte strains showed that this classification is unreliable. The aim of our study was to assess the usefulness of PCR-RFLP (restriction fragment length polymorphism) and sequencing in the characterization of T...

Ongoing large-scale land development for renewable energy projects in the Antelope Valley, located in the Western Mojave Desert, has been blamed for increased fugitive dust emissions and coccidioidomycosis incidence among the general public in recent years. Soil samples were collected at six sites that were destined for solar farm construction and were analyzed for the presence of the soil-borne fungal pathogen Coccidioides immitis which is endemic to many areas of central and southern California. We used a modified culture-independent nested PCR approach to identify the pathogen in all soil samples and also compared the sampling sites in regard to soil physical and chemical parameters, degree of disturbance, and vegetation...

Adhesion and biofilm formation, which can occur on abiotic and biotic surfaces, are key components in Candida pathogenicity. The aims of this study were to infer about the C. tropicalis clinical isolates ability to adhere and form biofilm on abiotic and biotic surfaces and to correlate that with the multilocus sequence typing and other virulence factors. Adhesion and biofilm formation were measured in 68 C. tropicalis isolates from 3 hospitals in China on abiotic (polystyrene) and biotic (human urinary bladder epithelial cell) surfaces by crystal violet assay and 2,3-bis (2-methoxy-4-nitro-5-sulfo-phenyl)-2H-tetrazolium-5-carboxanilide reduction assay...

Majocchi's granuloma is an intracutaneous or subcutaneous granulomatous inflammation caused by invasion of dermatophytic fungus, especially Trichophyton rubrum. This type of lesion is misdiagnosed frequently without proper auxiliary examination. Here, we report a case of widespread Majocchi's granuloma caused by T. rubrum in a 35-year-old woman with systemic lupus erythematosus for 9 years. The patient was initially misdiagnosed as SLE-associated skin lesions, which delayed her treatment and resulted in severe multiple disseminated lesions...

To date, only one case of post-traumatic endophthalmitis caused by Scedosporium dehoogii has been reported, but its contamination or colonization might not be precluded due to the absence of pathogenic isolation and/or pathological examination. We report the first case to our knowledge of S. dehoogii-induced subcutaneous scedosporiosis in a psoriatic patient. A 58-year-old man with 5-year history of psoriasis vulgaris and immunosuppressant therapy developed pyrexia and multiple subcutaneous abscesses on both knees...

Intracranial aspergillosis (ICA) is very rare in the immunocompetent individuals, usually misdiagnosed as a tumor or an abscess. A high index of clinical suspicion is required in patients who present with focal neurological deficits, headache, or seizures. We report the case of a 25-year-old immunocompetent female, who presented with a 15-month history of headache, seizures, left-sided proptosis and ophthalmoplegia, and right hemiparesis. Recovery from the symptoms and decrease in the lesion size seen on the radiological assessment were achieved through two decompressive craniotomies followed by prolonged combined systemic antifungal therapies...

Cryptococcosis is an infection that may be lethal in patients with nephrotic syndrome (NS). However, there is relatively limited epidemiological and clinical data about cryptococcosis in NS patients. We performed a pooled analysis to systemically summarize the epidemiology, risk factors, clinical and laboratory characteristics, treatments and outcomes of cryptococcosis in NS patients. Using data pooled from our hospital and studies identified via searches of three literature databases, 17 cases were identified for inclusion in this analysis...

Phaeohyphomycosis is an infection caused by a heterogeneous group of melanized fungi. Human infections due to members of genus Exophiala are rare but may occur at any part of the body. We herein report a case of an 85-year-old male with a history of bullous pemphigoid who presented with a chronic, non-healing wound on his right dorsal hand for a month. Direct microscopy of a pus sample from the base of the ulcer revealed strands of pigmented, moniliform hyphae. The isolate was identified as E. oligosperma based on morphological characters and sequencing of the rDNA internal transcribed spacers (ITS) and partial beta-tubulin gene...

Protothecosis is a disease caused by saprophyte aerobic unicellular algae belonging to the genus Prototheca. In dogs, it mainly occurs as a disseminated form, with initial clinical manifestations often referable to the gastrointestinal tract, followed by typical ocular and neurological signs. So far, Prototheca zopfii genotype 2 infection has been reported in severe forms of disseminated protothecosis, while in dogs has never been associated with cutaneous forms. In this study, we describe a case of Prototheca zopfii genotype 2 infection in a dog characterized by nodular and ulcerative dermatitis and with evidence of dissemination...

Infections caused by Trichophyton rubrum are very common in dermatological disease. It most often appears as superficial cutaneous mycosis, such as tinea manuum, tinea pedis, and tinea corporis. However, deep infection caused by T. rubrum was rarely reported. We describe a case of mixed type of deep infection caused by T. rubrum in a 45-year-old man with no significant immunodeficiency. This patient had a history of onychomycosis on the toenails without regular treatment for nearly 6 years. And, he had erythema, papule, and nodules on the submandibular area, neck, and chest for almost 1 year...

Cryptococcosis is a mycosis caused by yeasts of genus Cryptococcus, mainly the species C. neoformans and C. gattii that can affect humans and animals. These yeasts are widely distributed in the environment and are typically associated with avian droppings and decaying wood. Most infections are related to the respiratory tract, but the central nervous system and cutaneous lesions are also reported in the literature. The present report is a case of cryptococcosis in an 18-month-old unspayed female English Bulldog with the main complaint of weight loss and diarrhea...

The value of (1 → 3)-beta-D-glucans (BG) and galactomannan (GM) assays on diagnostic invasive fungal infections (IFIs) has been observed in adult ICU and in children with hematological malignancies. Only scant data evaluated non-hematological in pediatric intensive care unit (PICU). Here, we retrospectively analyzed the role of bacterial infection to the reactivity of BG and GM assays in PICU. The results showed that the overall prevalence of bacteremia was 13.8% (65/470). The most common underlying disease was pneumonia (81...

Diagnosis of invasive pulmonary aspergillosis (IPA) is challenging. The objective of the study was to assess the value of microbiological tests to the diagnosis of IPA in the absence of non-specific radiological data. A retrospective study of 23 patients with suspicion of IPA and positivity of some microbiological diagnostic tests was performed. These tests included conventional microbiological culture, detection of Aspergillus galactomannan (GM) antigen and in some patients (1 → 3)-β-D-glucan (BDG) and Aspergillus fumigatus DNA using the LightCycler(®) SeptiFast test...

BACKGROUND: The reports on disseminated candidiasis in dogs so far describe at least one predisposing factor. This case report, however, highlights candidiasis in a dog without any known predisposition. PATIENT: A 1.5-year-old intact female Hovawart dog was presented with subcutaneous nodules and polyuria/polydipsia. An excisional biopsy revealed a chronic pyogranulomatous and necrotizing inflammation with mycotic structures. The patient became febrile and lethargic, and developed lameness...

Despite their superficial localization in the skin, pathogenic dermatophytes can induce a complex but still misunderstood immune response in their hosts. The cell-mediated immunity (CMI) is correlated with both clinical recovery and protection against reinfection, and CD4+ T lymphocytes have been recognized as a crucial component of the immune defense against dermatophytes. Before the discovery of the Th17 pathway, CMI was considered to be only dependent of Th1 cells, and thus most studies on the immunology of dermatophytosis have focused on the Th1 pathway...

We report a case of phaeohyphomycosis caused by Alternaria infectoria in a 61-year-old heart transplant recipient with multiple skin lesions and pulmonary infiltrates. The infection spread via the haematogenous route from the primary cutaneous lesions into the lungs. The diagnosis was based on the histopathological examination, direct microscopy, skin lesion cultures and detection of Alternaria DNA in the bronchoalveolar lavage fluid using molecular methods. The treatment consisted of a combination of surgical excision and systemic antifungal therapy...
