Mucormycosis is increasingly encountered in immunosuppressed patients, such as those with haematological malignancies or stem cell transplantation. We present a descriptive analysis of 121 cases of mucormycosis from the Prospective Antifungal Therapy Alliance(®) registry (July 2004 to December 2008). Patients with proven or probable mucormycosis were enrolled and followed prospectively for 12 w...

This work reports the production of an exo-polygalacturonase (exo-PG) by Rhizomucor pusillus A13.36 in submerged cultivation (SmC) in a shaker at 45°C for 96 h. A single pectinase was found and purified in order to analyze its thermal stability, by salt precipitation and hydrophobic interaction chromatography. The pectinase has an estimated Mw of approximately 43.5-47 kDa and optimum pH of 4.0 ...

N-Phenylethylamides 1a-1f, were isolated from cultures of three limnic strains GW90a, GW102a and GW73a. Strain GW102a delivered additionally the compound cyclo(isoleucyldehydroalanyl) (2). The structure of these compounds were assigned by a detailed spectral analysis. Due to their potential use as herbicides, various related compounds 1a, 3, 4a and 4b were synthesized. The minimum inhibitory co...

2-[Methyl-(3-phenylpropionyl)amino]-benzoic acid (1e) was isolated from a culture of marine Streptomyces sp. strain B7747. Analogous compounds have potential importance as phytotoxic substances, hence compound 1e and the analogues 1a approximately 1d and 1f approximately 3a were synthesised. Antimicroalgal activity of the anthranilamide analogues showed that esters 1b, 1f and 2b were more activ...

From the ethyl acetate extract of the bacterial strain Cytophaga sp. AM13.1, among many known compounds, the new natural products 2,5-bis(3-indolylmethyl)pyrazine (2) and a highly symmetrical p-cyclophane named pharacine (5) were identified. In addition, tryptamine isovalerate (1) and p-hydroxyphenylacetamide (4), known as plant metabolites, were isolated and characterized from a microorganism ...

?-Galactosidases of Mucoromycota are rarely studied, although this group filamentous fungi is an excellent source many industrial enzymes. In study, 99 isolates from the genera Lichtheimia, Mortierella, Mucor, Rhizomucor, Rhizopus and Umbelopsis, were screened for their ?-galactosidase activity using a chromogenic agar approach. Ten best producers selected, was further investigated in submerged...

Mucormycosis, a fatal opportunistic infection in immunocompromised hosts, is caused by fungi belonging to the order Mucorales. Early diagnosis based on exact identification and multidisciplinary treatments is critical. However, identification of Mucorales fungi is difficult and often delayed, resulting in poor prognosis. This study aimed to compare the results of phenotypic and molecular identi...

This report presents a new case of mucormycosis encountered in penguin characterized by morphological variation of hyphae and presence of sporangia with numerous sporangiospores. A 4.5-year-old Magellanic penguin (Spheniscus magellanicus) died after exhibiting anorexia, poor nutritional condition and dyspnea. Multiple nodular lesions were observed in the thoracic and abdominal regions. Histopat...

OBJECTIVES Antifungal treatment of uncommon filamentous fungal infections is problematic. This study determined the in vitro susceptibility of miltefosine, as a single agent and in combination with posaconazole or voriconazole, against these pathogens. METHODS Susceptibility to miltefosine of 34 uncommon filamentous fungi was tested using CLSI broth microdilution M38-A2 methodology. Twenty is...
