Dermatophytes are common pathogens in superficial mycoses that are routinely identified by culture or PCR analysis of freshly collected skin, nail or hair specimens. Although clinical samples are normally processed without delay, practical or research issues may necessitate sample storage until later analysis. However, the influence of extended sample storage on the ability to recover fungi by culture vs. PCR analysis has not been specifically studied. Here, a total of 172 dermatological samples collected from 2013-2015 were examined before and after refrigerated storage at 4°C for 10...

BACKGROUND: Dermatophytosis is a frequent cutaneous infection affecting the keratinized tissues of humans, pets and livestock. Animals can carry dermatophytic elements asymptomatically and are considered to play an important role in the epidemiology of the disease. As exposure to any infected lesion free animals, especially cats, may lead to the development of infection in humans. OBJECTIVES: This study was done to determine the frequency of fungal agents isolated from skin and hair of cats living in rural areas of Meshkin-shahr, Iran...

Fungus ball is the most common form of non-invasive fungal rhinosinusitis. Aspergillusfumigatus (between 44.8% and 75%) and Aspergillusflavus (14%) are the two most common species recovered. However, recent advances in mycological laboratory methods have enhanced the detection and identification of fungi within fungus balls. Fusarium species, sometimes recovered from other forms of fungal rhinosinusitis such as allergic fungal rhinosinusitis or acute invasive fungal rhinosinusitis, are poorly associated with sinonasal fungus ball...

Identification of Fusarium at the level of the species complex is difficult with phenotypic methods, so it is necessary to use molecular sequencing methods. This study presents, for 33 isolates distributed among the four major species complexes, the performance of five identification schemes involving ITS (internal transcribed spacer), EF1α (translation elongation factor 1 alpha), RPB1 (largest subunit of RNA polymerase) and RPB2 (second largest subunit of RNA polymerase) genes and two databases: GenBank and Fusarium MLST (MultiLocus Sequence Typing)...

Aspergillosis represents a spectrum of fungal diseases which are caused by fungi of the genus Aspergillus. Animal models have been developed and used to address immune-based mechanisms of defense against these fungi. Invertebrate models enabled mass screening of virulence attributes of Aspergillus species as well as mechanisms of acquired resistance to antifungal agents. This review represents a concise view of cellular and humoral participants in an immune response to Aspergillus gained mostly from rodent models of aspergillosis...

Fungi from the Conidiobolus genus have been implicated in the development of chronic invasive fungal rhinosinusitis, mainly in tropical countries. The mycosis associated to these fungi may cause irreversible facial deformities and is potentially fatal. The authors present the first case of a chronic invasive fungal rhinosinusitis due to Conidiobolus coronatus diagnosed in a 66-year-old Caucasian male patient, living in Portugal without any travels abroad and complaining of progressive refractory nasal obstruction, facial pain and anosmia...

Candida blood steam infection is a life-threatening disease that seems to be under estimated. Understanding epidemiology of such disease is crucial for improved diagnosis, optimized treatment, and better outcome. Through this retrospective study, we aimed to determine the incidence of candidemia in a secondary care hospital, and to describe the epidemiology and outcome of candidemia among adult patients. The incidence of candidemia for all age groups was 0.24, 0.16 and 0.15 cases/1000 patient-days in 2014, 2015 and 2016 respectively...

Pulmonary mucormycosis is a rare opportunistic infection caused by Mucormycosis. This fungal infection is uncommon in immunocompetent individuals. Because of its various clinical and imaging manifestations, it is a diagnostic challenge to distinguish pulmonary mucormycosis from other pulmonary diseases, such as carcinoma. Herein, we report a case of pulmonary mucormycosis presenting as Pancoast syndrome and bone destruction of ribs. A 46-year-old Chinese woman was admitted due to pain in chest, right neck and arm for four months and hoarseness for one week...

Gastrointestinal basidiobolomycosis (GIB), a rare fungal infection associated with high mortality, has been reported worldwide mainly from tropical and subtropical regions of Asia, USA, and Latin America. The clinical manifestations are highly diverse and non-specific depending on the underlying disease, but fever, abdominal pain, weight loss, diarrhea, constipation and chills have been observed. There are no prominent risk factors for GIB but climatic conditions and life style are related to this infection in arid and semi-arid regions...

Trichoderma species are saprophytic filamentous fungi that can be found all over the word. These fungi show increasing medical importance as opportunistic human pathogens, particularly in immunocompromised patients. Invasive infections due to Trichoderma are rare and definitive diagnosis is complex to achieve because of the lack of specific diagnosis tools. We report in this work the first proven case of invasive pulmonary infection due to T. longibrachiatum in a 69-year-old white male with hematologic malignancy...

OBJECTIVE: The effect of candidemia on immunologic parameters in breast tumor bearing patients is not well studied. Here, we hypothesised that candidemia in the tumor background may change the outcome of immunologic parameters and tumor condition. METHOD: Mice were divided into four groups, including normal, tumor, Candida infected (only Candidiasis) and tumor/Candidiasis groups. Tumor changes were recorded daily after tumor transplantation and induction of candidemia...
