Mucormycosis is an emerging angioinvasive infection caused by the ubiquitous filamentous fungi of the Mucorales order of the class of Zygomycetes. Mucormycosis has emerged as the third most common invasive mycosis in order of importance after candidiasis and aspergillosis in patients with hematological and allogeneic stem cell transplantation. Mucormycosis also remains a threat in patients with...

Azoles are important compounds for the treatment of fungal infections. This review focuses on three azoles: isavuconazole, ravuconazole and albaconazole (Stiefel). These drugs exhibit a broad spectrum of activity in vitro, including activity against several fungal isolates that are resistant to other azoles. However, poor or limited activity of these compounds has been demonstrated against spec...

Many strains of zygomycetes and actinomycetes were found to convert milbemycin A4 (1a) to 13 beta-hydroxymilbemycin A4 (1b). Among these strains, Cunninghamella echinulata ATCC 9244 had the most efficient 13 beta-hydroxylation ability on milbemycins. In the conversion of milbemycin A3 (2a), 29-hydroxymilbemycin A4 (4a), and 30-hydroxymilbemycin A4 (5a) with this strain, only 13 beta-hydroxylate...

Fungi belonging to class Zygomycetes become pathogenic in certain predisposing conditions; principally diabetes mellitus, immunosuppression, trauma or burns. We report a case of a 31-year-old man with acute promyelocytic leukemia who developed infection of the sino-oral cavity, due to Absidia corymbifera during a neutropenic phase following induction chemotherapy. A provisional diagnosis of zyg...

We collected mature tanoak (Lithocarpus densiflorus (Hook. & Arn.) Rehder) roots from five stands to characterize the relative abundance and taxonomic richness of root-associated fungi. Fungi were identified using polymerase chain reaction (PCR), cloning, and sequencing of internal transcribed spacer (ITS) and 28S rDNA. A total of 382 cloned PCR inserts were successfully sequenced and then clas...

Abstract The alfalfa weevil ( Hypera postica Gyllenhal, Coleoptera: Curculionidae) is a major pest of crops. Chemical control measures are inefficient, but the larvae often infested by parasitoid wasps genus Bathyplectes Förster (Hymenoptera: Ichneumonidae), which offer potential biological strategy. development effective requires identification species, conventional methods involve rearing par...

Bryophilous fungi associated with two bryophyte species in the region of delta Tamil Nadu that is, mosses Polytrichum commune and Bryum capillare (Ptychostomum capillare) were studied during winter season. These bryophytes Desiccation-Tolerance Bryophytes plant (DTB), ability to lose virtually all free intracellular water then recover normal function upon rehydration is one most remarkable feat...

A 9-month-old steer was autopsied due to recurrent ruminal tympany. A macroscopic examination found an enlarged caudal mediastinal lymph node, and a section of the lymph node revealed necrosis with marked calcification, similar to tuberculous lymphadenitis. Histopathologically, the lesion consisted of multiple coagulative necrotic foci and fibrosis with macrophage, lymphocyte, eosinophil and mu...

Hospital construction and renovation activities are an ever-constant phenomenon in healthcare facilities, causing dust contamination and possible dispersal of fungal spores. We reviewed fungal outbreaks that occurred during construction and renovation over the last 4 decades as well as current infection prevention strategies and control measures. Fungal outbreaks still occur in healthcare setti...

Peritonitis is a common problem in patients undergoing peritoneal dialysis. However, peritonitis due to Cunninghamella (C.) bertholletiae, a fungus of the class Zygomycetes, is rare. We present a case of fungal peritonitis in a patient on continuous ambulatory peritoneal dialysis due to kidney rejection. Direct examination of the patient's peritoneal fluid showed fungal hyphae, and the culture ...
