| Lipases are placed only after proteases and carbohydrases in world enzyme market and share about 5% of enzyme market. They occur in plants, animals and microorganisms and are accordingly classified as plant, animal and microbial lipases. Wherever they exist, they function to catalyze hydrolysis of triglycerides to glycerol and fatty acid. Like carbohydrases and proteases, lipases of microbial origin enjoy greater industrial importance as they are more stable (compared to plant and animal lipases) and can be obtained in bulk at low cost. Majority of yeast lipases are extracelluar, monomericglycoproteins with molecular weight ranging between ~33 to ~65 kD. More than 50% reported lipases producing yeast, produce it in the forms of various isozymes. These... |

| Background: The exopolysaccharides (EPS) produced by yeast exhibit physico-chemical and rheological properties, which are useful in the production of food and in the cosmetic and pharmaceutical industries as well. The effect was investigated of selected carbon sources on the biosynthesis of EPS by Candida famata and Candida guilliermondii strains originally isolated from kefirs. Results: The biomass yields were dependent on carbon source (sucrose, maltose, lactose, glycerol, sorbitol) and ranged from 4.13 to 7.15 g/L. The highest biomass yield was reported for C. guilliermondii after cultivation on maltose. The maximum specific productivity of EPS during cultivation on maltose was 0.505 and 0.321 for C. guilliermondii and C. famata, respectively. The... |

| Recently, propolis has been attracting the attention of researchers due to various biological activities and therapeutic properties. In Brazil, propolis is produced all year long, so there may be some seasonal variations. This work was carried out in order to compare propolis collected during the four seasons by its in vitro antimicrobial activity on yeast pathogens isolated from human infections. Propolis was produced by africanized honeybees in Botucatu, São Paulo State, collected throughout a year and pooled by season. Hydroalcoholic solutions of propolis were prepared with each pool and diluted in agar, using serial concentrations of propolis from each pool. A determination of minimal inhibitory concentration (MIC) was performed. The results show that... |

| Endopleura uchi (Huber) Cuatrec. is an Amazon species traditionally used as treatment for inflammations and female disorders. Bergenin was isolated from ethyl acetate fraction of bark of E. uchi by using column chromatography over sephadex LH-20 and then silica gel 60 flash. Its structure was identified on the basis of its NMR spectra. The antimicrobial activity of bergenin and fractions of methanol extract of E. uchi were evaluated against ATCC microorganisms (Escherichia coli, Salmonella enteritidis, Pseudomonas aeruginosa, Enterococcus faecalis, Staphylococcus aureus, Candida albicans, C. guilliermondii, Aspergillus flavus, A. nidulans). Clinically isolated strains of all of these microorganisms, along with C. tropicalis, A. niger, Shigella sonnei,... |

| Extracts from the dried pericarp of Sapindus saponaria L. (Sapindaceae) fruits were investigated for their antifungal activity against clinical isolates of yeasts Candida albicans and C. non-albicans from vaginal secretions of women with Vulvovaginal Candidiasis. Four clinical isolates of C. albicans, a single clinical isolated of each of the species C. parapsilosis, C. glabrata, C. tropicalis, and the strain of C. albicans ATCC 90028 were used. The hydroalcoholic extract was bioactivity-directed against a clinical isolate of C. parapsilosis, and showed strong activity. The n-BuOH extract and one fraction showed strong activity against all isolates tested. Further column-chromatography on silica gel separation of this fraction afforded two pure triterpene... |

| A mastite representa um dos problemas mais sérios que afetam as fazendas de gado leiteiro. As mastites clínica e subclínica em bovinos, devido a leveduras, são causadas principalmente por espécies do gênero Candida. O objetivo deste trabalho foi identificar quais espécies dessa levedura estavam presentes em amostras de leite obtidas da glândula mamária de vacas apresentando mastite. Um total de 428 amostras de leite foi coletado nos estados de São Paulo, Paraná, Santa Catarina e Rio Grande do Sul. A identificação foi realizada por meio de critérios fenotípicos e fisiológicos. Foi possível isolar seis espécies de Candida em 55 (12,8%) das amostras. As espécies mais frequentes foram C. krusei(34,6%), C. parapsilosis(25,4%), C. tropicalis (18,2%) e C.... |

| ABSTRACT Background: The impact of central venous catheter (CVC) removal on the outcome of patients with candidemia is controversial, with studies reporting discrepant results depending on the time of CVC removal (early or any time during the course of candidemia). Objective: Evaluate the effect of time to CVC removal, early (within 48 h from the diagnosis of candidemia) vs. removal at any time during the course of candidemia, on the 30-day mortality. Methods: Retrospective cohort study of 285 patients with candidemia analyzing CVC removal within 48 h (first analysis) or at any time (second analysis). Results: A CVC was in place in 212 patients and was removed in 148 (69.8%), either early (88 patients, 41.5%) or late (60 patients, 28.3%). Overall, the... |

| ABSTRACTThe antifungal activity of some statins against different fungal species has been reported. Thus, at the first moment, the in vitro antifungal activity of simvastatin, atorvastatin and pravastatin was tested againstCandida spp. and Cryptococcus spp. Then, in a second approach, considering that the best results were obtained for simvastatin, this drug was evaluated in combination with antifungal drugs against planktonic growth and tested against biofilms ofCandida spp. and Cryptococcus spp. Drug susceptibility testing was performed using the microdilution broth method, as described by the Clinical and Laboratory Standards Institute. The interaction between simvastatin and antifungals against planktonic cells was analyzed by calculating the... |

| Bacteria that attach to surface aggregate in a hydrated polymeric matrix of their own synthesis to form biofilms. These represent microbial societies with their own defense and communication system. Transitioning from acute to chronic infection is frequently associated with biofilm formation.Bacteria in biofilms are innately more resistant to antimicrobial agents. The presence of indwelling medical devices increases the risk for biofilm formation and subsequent infection. The current antibiotic therapies are of limited effectiveness in resolving biofilms infection.This review attempts to discuss the stages in biofilm formation, their pathogenic mechanisms, effect of antimicrobial agents, detection and eradication of the biofilms. |

| Problems with resistance to antifungal drugs have emerged due to an increase in the incidence of systemic fungal infections and widespread use of antifungal agents. Accordingly, efforts have been made to develop adequate fungal susceptibility tests. The ideal test should have high intra and inter-laboratory reproducibility, good correlation with the clinical outcome, and should be easy to perform. While no such test has yet been developed, advances have been made. Over the past decade, many reports of fungal resistance have been published, most of them in AIDS patients. Though the frequency of resistant strains is still low in neutropenic cancer patients, and is mostly limited to Candida glabrata and Candida krusei, resistance to Candida albicans has also... |

| Several cases of Candida bloodstream infections were documented from June to October 2004 at a tertiary care center in Bogotá, Colombia. Since no cases of candidemia had occurred during the preceding four months, an outbreak was declared. As a result, a microbiological study, a revision of infection control practices and a case-control study were performed. In all, 18 cases of candidemia were ascertained. Parenteral nutrition (p=0.04), presence of a central line (p=0.03), and severity of illness (p=0.03) were associated with candidemia in bivariate analysis. Diverse Candida species were observed. Candida parapsilosis contamination was found in plastic containers used for transient intravenous (IV) medication storage at the bedside, plastic bags reused for... |

| Onychomycosis is a fungal infection of nails caused by dermatophytes, yeasts and moulds, accounting for about 50% of onychopathies. A high frequency of onychomycosis caused by Candida species has been reported during the last few years in northeast Brazil, as well as in other regions of the world. A clinical diagnosis of onychomycosis needs to be confirmed through laboratory exams. We evaluated the importance of serial repetition of direct microscopic exams and fungal culture for the diagnosis of onychomycosis in the city of Fortaleza, Ceará, in northeast Brazil. We first made a retrospective study of 127 patients with onychomycosis, identifying the fungi that had been isolated from fingernails and toenails. We then made a prospective study of 120... |
