Impact of prolonged storage of clinical samples at 4 °C on the recovery of dermatophytes by culture or PCR analysis
Publication date: Available online 11 February 2019Source: Journal de Mycologie MédicaleAuthor(s): K. Nilsson, M. Friberg, O. Rollman, E. TanoAbstractDermatophytes 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 ...

Maxillary fungus balls due to Fusarium proliferatum
Publication date: Available online 6 February 2019Source: Journal de Mycologie MédicaleAuthor(s): T. Radulesco, A. Varoquaux, S. Ranque, P. Dessi, J. Michel, C. CassagneAbstractFungus ball is the most common form of non-invasive fungal rhinosinusitis. Aspergillus fumigatus (between 44.8% and 75%) and Aspergillus flavus (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 a...

Green synthesis of gold nanoparticles using Fusarium oxysporum and antibacterial activity of its tetracycline conjugant
ConclusionsBiosynthesis of GNPs by F. oxysporum has advantages including fast growth rate, inexpensive biomass handling, safety and easy processing. Conjugation of tetracycline with GNPs enhances antibacterial activity, which may have significant therapeutic applications. (Source: Journal of Medical Mycology)

Molecular identification of Fusarium species complexes: Which gene and which database to choose in clinical practice?
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). In our practice, the identification of the fungus from a culture is performed with EF1α and from a primary sample with ITS, using in both cases the specific database Fusarium MLST.

Usefulness of animal models of aspergillosis in studying immunity against Aspergillus infections
Publication date: Available online 25 January 2019Source: Journal de Mycologie MédicaleAuthor(s): I. Mirkov, A. Popov Aleksandrov, B. Lazovic, J. Glamoclija, M. KataranovskiAbstractAspergillosis 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...

Molecular characterization and antifungal susceptibility profile of dermatophytes isolated from scalp dermatophyte carriage in primary school children in Arak city, Center of Iran
ConclusionIn the study, T. tonsurans was the most common species isolated from asymptomatic carriers and of the four antifungals tested, terbinafine had the most active antifungal in vitro against all isolates. Identifying and treating scalp dermatophyte carriers can prevent the spread of tinea capitis in the community. (Source: Journal of Medical Mycology)

Chronic invasive rhinosinusitis by Conidiobolus coronatus, an emerging microorganism
Publication date: Available online 10 January 2019Source: Journal de Mycologie MédicaleAuthor(s): J. Pestana, A. Carmo, J.C. Ribeiro, R. ToméAbstractFungi 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 p...

Ocular infection caused by Hormographiella aspergillata: A case report and review of literature
We report a case of 70-year-old female with corneal ulcer and endophthalmitis caused by this agent. The patient had an intraocular implantation of lens following a cataract surgery. Corneal tissue obtained during therapeutic penetrating keratoplasty showed presence of septate hyphae on microscopy and culture grew H. aspergillata which was confirmed by sequencing of ITS region. Patient was started on systemic voriconazole and topical natamycin, however the eye could not be salvaged. To our knowledge, this is the first report of ocular infection caused Hormographiella aspergillata in an immunocompetent patient. (Source: Jour...

Epidemiologic characteristics of adult candidemic patients in a secondary hospital in Kuwait: A retrospective study
Publication date: Available online 19 December 2018Source: Journal de Mycologie MédicaleAuthor(s): K. Alobaid, Z. KhanAbstractCandida 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 ...

Publication date: Available online 12 December 2018Source: Journal de Mycologie MédicaleAuthor(s): J. Yang, J. Zhang, Y. Feng, F. Peng, F. FuAbstractPulmonary 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.
