Fungi can cause various diseases, and some pathogenic fungi have been detected in the water of dental equipment. This environment offers suitable conditions for fungal biofilms to emerge, which can facilitate mycological contamination. This study verified whether the water employed in the dental units of two dental clinics at the University of Franca was contaminated with fungi. This study also...

The antifungal activity of N-chlorotaurine (NCT), a long-lived oxidant produced by stimulated human leucocytes, was investigated. Incubation of Aspergillus spp., Candida spp., Fusarium spp., Penicillium spp. and Alternaria spp. in 1% NCT (55 mM) for 1-4 h produced a log10 reduction in cfu of between 1 and 4. In samples of nasal secretion, killing was significantly hastened (30 min), which may b...

Fusarium spp. have emerged as major opportunistic fungal agents. Since new antifungal agents exhibit variable activity against Fusarium isolates depending on the species, rapid identification at the species level is required. Conventional culture methods are difficult, fastidious, and sometimes inconclusive. In this work, we sequenced a 440-bp fragment encoding the 28S rRNA from 33 Fusarium iso...

Legume crops are exposed to infection by fungal pathogens, which often results in contamination with mycotoxins. The aim of this study was to evaluate the level of field resistance/susceptibility of edible and fodder pea cultivars to the colonization of seeds by fungal pathogens in two subsequent seasons, as well as to identify the pathogens present in the seeds of the tested cultivars. Alterna...

بیماری پوسیدگی فوزاریومی ریشه و طبق پیاز در سراسر جهان وجود دارد و در چند سال اخیر در مناطق عمده کشت پیاز و به خصوص در استان آذربایجان شرقی گسترش زیادی پیدا کرده است و در حال حاضر مهمترین بیماری پیاز در ایران می‏باشد. بنابراین به منظور شناسایی و مطالعه بیماریزایی قارچ های فوزاریوم (fusarium spp.) عامل این بیماری در مناطق عمده کشت این محصول در دو استان آذربایجان شرقی و آذربایجان غربی در تابستان ...

Fusarium spp., have been recognized during the past decade to cause disseminated infection, particularly in granulocytopenic patients undergoing intensive antileukemic chemotherapy or bone marrow transplantation. The lung, sinuses, and skin are the primary portals of entry. The periungual regions of the toes notably may be a particularly important site of initial invasion. Invasive Fusarium inf...

The in vitro antifungal activity of a new triazole derivative, voriconazole, was compared with those of itraconazole and amphotericin B against 67 isolates of Aspergillus flavus, Aspergillus fumigatus, Bipolaris spp., Fusarium oxysporum, Fusarium solani, Pseudallescheria boydii, Rhizopus arrhizus, Blastomyces dermatitidis, Histoplasma capsulatum, and Sporothrix schenckii. The in vitro activitie...

Soy products are a main component of animal feed. Because mycotoxins may harm farm animals, undermining productivity and health, a mycological and toxigenic screening was carried out on 36 batches used in animal feed, collected in 2008, 2009 and 2010 in Italy. The investigated mycoflora of a subset of soy seed (n = 6) suggested that Aspergillus spp. and Fusarium spp. frequently colonize soy see...

Six fungal species (Fusarium sp, Exophiala jeanselmei, Penicillium spp, Aspergillus niger, Paecilomyces spp, and Alternaria spp) were used to inoculate soft contact lenses. Four types of soft lenses were used: high-water (58%) and low-water (38%) content lenses and lenses that were unworn or worn for 1 day. The fungi displayed a range of macroscopic and microscopic features that allowed differe...
