species associated with citrus blackfly () from an agroecological polyculture in Brazil, including an augmented description of .

The objectives of this study were to report species associated with (Hemiptera: Aleyrodidae) collected from citrus leaves from an agroecological polyculture in Brazil, assess sexual reproductive mode of the species with unknown sexual stages, and provide an augmented description of , for which we discovered a sexual stage. Nineteen isolates were recovered from . These fungi belong to three species complexes, i.

Optimization of L-glutaminase production by Monascus ruber URM 8542 isolated from ice cream industrial effluent.

L-glutaminase is a hydrolytic enzyme with wide biotechnological applications. Mostly, these enzymes are employed in the feed industry for flavor enhancement and acrylamide mitigation. Also, L-glutaminase may have antiviral and antineoplastic effects making it a good choice for pharmaceutical applications.

Molecular identification of Brazilian Fusarium strains: sources of proteases with milk-clotting properties.

Fusarium is a genus of ubiquitous fungi that comprises mycotoxigenic animal and plant pathogens. These fungi have the ability to exploit a wide range of substrates and hosts, indicating their great potential for enzyme production; however, this aspect is understudied. Therefore, the present study aimed for revaluating the identity of twenty-three Fusarium strains maintained in the University Recife Mycology (URM) culture collection, Brazil, and to evaluate their potential for proteases production and the milk-clotting activity of these proteases.

Evaluation of Mycotoxin Production and Phytopathogenicity of the Entomopathogenic Fungi Fusarium caatingaense and F. pernambucanum from Brazil.

Fusarium incarnatum-equiseti species complex (FIESC) is considered as one of the richest insecticolous species. Fusarium species synthesize toxic secondary metabolites that are not fully understood. Mycotoxin production and pathogenicity on germinating seeds, seedlings, and leaves must be carefully studied for the use of Fusarium species in the biological control of insect pests.

Morphology, phylogeny, and sexual stage of Fusarium caatingaense and Fusarium pernambucanum, new species of the Fusarium incarnatum-equiseti species complex associated with insects in Brazil.

Based on morphological and molecular phylogenetic markers and the fertility of sexual crosses, two novel species of Fusarium associated with Dactylopius opuntiae (Hemiptera: Dactylopiidae) and Aleurocanthus woglumi (Hemiptera: Aleyrodidae) from northeastern Brazil are described as Fusarium caatingaense and F. pernambucanum. Partial sequences of five loci were generated for 29 entomopathogenic Fusarium isolates.

Elastin increases biofilm and extracellular matrix production of Aspergillus fumigatus.

Aspergillus fumigatus is an opportunistic saprobe fungus that accounts for 90% of cases of pulmonary aspergillosis in immunosuppressed patients and is known for its angiotropism. When it reaches the respiratory tract, A. fumigatus interacts with structural components and blood vessels of the lungs, such as elastin.

Polyphasic Approach Including MALDI-TOF MS/MS Analysis for Identification and Characterisation of Fusarium verticillioides in Brazilian Corn Kernels.

Fusarium verticillioides is considered one of the most important global sources of fumonisins contamination in food and feed. Corn is one of the main commodities produced in the Northeastern Region of Brazil. The present study investigated potential mycotoxigenic fungal strains belonging to the F.

Differential expression of the pr1A gene in Metarhizium anisopliae and Metarhizium acridum across different culture conditions and during pathogenesis.

The entomopathogenic fungi of the genus Metarhizium have several subtilisin-like proteases that are involved in pathogenesis and these have been used to investigate genes that are differentially expressed in response to different growth conditions. The identification and characterization of these proteases can provide insight into how the fungus is capable of infecting a wide variety of insects and adapt to different substrates. In addition, the pr1A gene has been used for the genetic improvement of strains used in pest control.

Fungemia by Candida pelliculosa (Pichia anomala) in a neonatal intensive care unit: a possible clonal origin.

Neonatal candidemia can occur, however, infections caused by Candida pelliculosa are rare. Here, we describe an outbreak of candidemia caused by C. pelliculosa among babies hospitalized in a neonatal intensive care unit.

Invasive infection in an acute myeloblastic leukemia patient due to triazole-resistant Candida tropicalis.

Non-albicans Candida species are being increasingly reported as causes of nosocomial fungal infections. For example, invasive candidiasis caused by C. tropicalis has been associated with hematologic malignancies.

Trichosporon inkin Esophagitis: An Uncommon Disease in a Patient with Pulmonary Cancer.

Trichosporon species are usually opportunistic pathogens. Here, we present a case of esophagitis caused by T. inkin in a 54-year-old woman with pulmonary cancer and severe neutropenia in whom the susceptibility profile of the isolate against azoles and polyenes was verified.
