The aim of present study was to enhance topical permeation of clotrimazole gel preparation by using various permeability enhancers such as coconut oil, pistachio oil and sodium lauryl sulphate (SLS). Clotrimazole gel preparations were prepared and optimized by using three factor, five level central composite design. A second-order polynomial equation was generated in order to estimate the effect of independent variables i.e. coconut oil (X1), pistachio oil (X2) and sodium lauryl sulphate (X3) at various dependent variables i...

OBJECTIVES: To generate lycopene-overproducing strains of the fungus Mucor circinelloides with interest for industrial production and to gain insight into the catalytic mechanism of lycopene cyclase and regulatory process during lycopene overaccumulation. RESULTS: Three lycopene-overproducing mutants were generated by classic mutagenesis techniques from a β-carotene-overproducing strain. They carried distinct mutations in the carRP gene encoding lycopene cyclase that produced loss of enzymatic activity to different extents...

Lactobacillus rhamnosus R-2002 strain isolated from Armenian pickled cheese sample has a fungicide effect, which was carried out by the first-time designed method. The fungicide effect of LAB strain was expressed after 5 days of co-cultivation with Mucor plumbeus and 6 days of co-cultivation with Penicillium aurantioviolaceum. The growth as well as the antifungal activity of L. rhamnosus R-2002 was shown to directly depend on the nature of the medium's carbon source. The antifungal activity of this strain against both moulds was inhibited when the combination of 10 g l(-1) glucose and 10 ml l(-1) ethanol in the medium was used as a carbon source...

BACKGROUND: A 2015 AAST trial reported a 32% mortality for pelvic fracture patients in shock. Angioembolization (AE) is the most common intervention; the Maryland group revealed time to AE averaged 5 hours. The goal of this study was to evaluate the time to intervention and outcomes of an alternative approach for pelvic hemorrhage. We hypothesized preperitoneal pelvic packing (PPP) results in a shorter time to intervention and lower mortality. METHODS: In 2004 we initiated a PPP protocol for pelvic fracture hemorrhage...

Protein kinase A (PKA) activity is involved in dimorphism of the basal fungal lineage Mucor. From the recently sequenced genome of Mucor circinelloides we could predict ten catalytic subunits of PKA. From sequence alignment and structural prediction we conclude that the catalytic core of the isoforms is conserved, and the difference between them resides in their amino termini. This high number of isoforms is maintained in the subdivision Mucoromycotina. Each paralogue, when compared to the ones form other fungi is more homologous to one of its orthologs than to its paralogs...

Sexual communication between complementary mating partners in the fungal group of zygomycetes is mediated by the trisporoid pheromone system. A key enzyme towards biosynthesis of hormonally active trisporoids is 4-dihydromethyltrisporate dehydrogenase (TSP1), an enzyme occurring in all zygomycetous fungi. Trisporic acid and some of its precursor molecules serve as pheromones for recognizing complementary mating partners and for induction of the differentiation program towards sexual spore formation. In the parasitic zygomycete Parasitella parasitica, a biotrophic fusion parasite infecting many other zygomycetes, these substances have an additional function: They are also responsible for host-parasite recognition and the formation of the characteristic infection structures...

The influence of a static magnetic field (SMF) on crude enzyme extracts with proteolytic activity is described and discussed. Proteolytic enzymes, which hydrolyze peptide bonds, and fibrinolytic enzymes, which dissolve fibrin clots, have industrial relevance, and applicability dependent on improvements of productivity and activity. We investigated whether a moderate SMF affects proteolysis in different in vitro tests: general proteolysis of azocasein substrate, and static and dynamic fibrinolytic processes (to compare fibrin gel configuration under exposure)...

BACKGROUND: Mucormycosis has emerged as a rare but frequently fatal invasive fungal disease. Current knowledge on paediatric mucormycosis is based on case reports and small series reported over several decades. Contemporary data on a large cohort of patients is lacking. METHODS: Two large international registries (Zygomyco.net and FungiScope™) were searched for mucormycosis cases in ≤19 year-old patients. Cases enrolled between 2005 and 2014 were extracted, and dual entries in the two databases merged...

The usefulness of pellets industrially manufactured with spores of parasiticide fungi as a contribution to integrated nematode control was assessed in grazing horses throughout sixteen months. Two groups of 7 Pura Raza Galega autochthonous horses (G-T and G-P) were dewormed pour-on (1mg Ivermectin/kg bw) at the beginning of the trial, and other group (G-C) remained untreated. The G-P was provided daily with commercial pellets to which was added a mixture of fungal spores during the industrial manufacturing (2×10(6) spores of Mucor circinelloides and same dose of Duddingtonia flagrans/kg), and G-T and G-C received pellets without spores...

Mucormycosis is an invasive infection caused by opportunistic fungi. Rhizopus, Lichtheimia, Mucor and Rhizomucor are the most common isolated genera. Primary cutaneous mucormycosis is usually related to traumatic injuries, but immunocompromised cases are associated with underlying conditions such as diabetes mellitus and malignancies. The treatment of choice is surgical debridement and liposomal amphotericin B. We present a 40-year-old male with fever and a painful necrotic lesion on the middle back and history of poorly controlled diabetes mellitus...

OBJECTIVES: Previously we demonstrated the benefit of isavuconazole in treating murine mucormycosis due to Rhizopus. We wanted to determine the efficacy of isavuconazole in treating murine mucormycosis caused by Mucor, the second most common cause of the disease. Furthermore, because we previously determined that Rhizopus possesses the target enzyme for echinocandins and micafungin has activity against murine mucormycosis, we compared the activity of combination therapy (isavuconazole + micafungin) with placebo, either drug alone or standard therapy of liposomal amphotericin B (LAmB) in treating pulmonary murine mucormycosis caused by Rhizopus delemar...

We analyzed the incidence, clinical characteristics, prognostic factors and outcome of CNS infections in consecutive patients with receiving umbilical cord blood transplantation (UCBT) (n = 343) or HLA-matched sibling donor stem cell transplantation (MST) (n = 366). Thirty-four CNS infections were documented at a median time of 116 days after transplant (range, 7-1161). The cumulative incidence (CI) risk of developing a CNS infection was 0.6% at day +30, 2.3% at day +90 and 4.9% at 5 years. The 5-year CI of CNS infection was 8...

Microbiological source tracking (MST) for food industry is a rapid growing area of research and technology development. In the paper at hand, a new library-independent approach for microbial source tracking is presented. It is based on a high-throughput liquid micro-cultivation and FTIR spectroscopy. In the approach, FTIR spectra obtained from microorganisms isolated along the production line and a product are compared to each other. We tested and evaluated the new source tracking approach by simulating a source tracking situation...

Mucormycosis fungemia is rarely documented since blood cultures are nearly always negative. We describe a case of Mucor circinelloides fungemia in a patient with a history of a sinus infection, sarcoidosis, and IgG deficiency. The identity of the isolate was supported by its microscopic morphology and its ability to convert into yeast forms under anaerobic conditions. The early detection, initiation of liposomal amphotericin B treatment, and reversal of underlying predisposing risk factors resulted in a good outcome...

Mucor fungus infection is a rare opportunistic infection, rapidly progressive and often fatal in immunocompromised patients, or in patients with chronic debilitating diseases. We report six cases of trauma patients with mucormycosis. Three had severe thermal burns, one of them with a medical history of diabetes mellitus. The other three patients suffered from severe soft tissue injuries caused by traffic accidents. In all cases there had been spontaneous exposure and contact of the wounds with soil. During hospitalization, fungi cultures and/or biopsies of all wounds were performed and all resulted positive...

Mucorales comprises fungi commonly isolated as saprobes from soil, dung, stored grains and plants. Although these fungi have been studied in several countries, there are relatively a few reports of them in semi-arid areas. Therefore, the aims of the present study were to assess and compare the Mucorales communities in dung from different species and breeds of herbivores in the semi-arid of Pernambuco, based on the frequency of occurrence and species richness of these fungi. Samples of dung collected in the cities of Arcoverde, Serra Talhada and Sertânia were incubated in moist chambers in triplicate...

Silage, one of the most important feed sources for cattle, is vulnerable to contamination by spoilage moulds and mycotoxins because ensilage materials are excellent substrates for fungal growth. The aim of this study was to identify the mycobiota of sorghum silages, to determine the presence of aflatoxins and fumonisins, and to correlate these results with physical parameters of the silage. A total of 275 samples of sorghum were collected from dairy farms in the south-west region of Uruguay were silage practices are developed...
