| 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... |

| 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... |

| 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,... |

| 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. |

| Candida is an opportunistic pathogen that affects highrisk patients who are either immunocompromised or critically ill and is associated with almost 80% of all nosocomial fungal infections, representing the major cause of fungemia with high mortality rates (40%). Candida albicans is the main cause of candidemia and among the non-albicans species C. parapsilosis, C. glabrata and C. tropicalis are the most frequent agents. The aim of this study was to evaluate the distribution of Candida species in two tertiary hospitals in Recife, Northeastern Brazil. It began by surveying all positive Candida cultures processed by the microbiology laboratory from September 2003 to September 2006. The cultures, originated from various types of biological material (blood,... |

| O gênero Candida é composto por leveduras que vivem como comensais na microbiota de homens e animais. Em geral, não causam nenhum dano aos seus hospedeiros, entretanto, em virtude de desequilíbrios nas defesas química, física e imunológica, esses microrganismos podem se tornar patogênicos. Infecções por Candida spp. são pouco frequentes na Medicina Veterinária no entanto, nos últimos anos, tem sido observado aumento considerável de relatos de enfermidades causadas por essas leveduras, acometendo diferentes animais. Várias espécies do gênero são implicadas em quadros infecciosos, sendo a C. albicans a principal delas, seguida por C. tropicalis e C. parapsilosis. Considerando-se o potencial patogênico do gênero Candida, aliado ao surgimento de cepas... |

| Estudou-se o comportamento de leveduras do gênero Candida a antifungicos, pela determinação da Concentração Inibitória Mínima (CIM) e da Concentração Fungicida Mínima (CFM) "in vitro"de 30 cepas de Candida frente aos antifungicos: miconazol, cetoconazol e anfotericina B. Empregou-se o método de diluição em meio líquido e os antifungicos foram diluídos visando proporcionar concentrações a partir de 0,06 a 128 μg/mL. O inóculo foi padronizado ajustando-se a suspensão para conter 1X 106 ufc/mL. A concentração para a qual houve maior convergência de cepas foi de 1 μg/mL (26,5%) para anfotericina B. Para miconazol foi de 16 μg/mL (26,0%) e para cetoconazol 32 μg/mL (23,0%). Os valores de CFM foram de 2 μg/mL (23,5%) para anfotericina B, de 16 e 64 μg/mL (26,5%)... |

| 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... |

| The increasing magnitude of antifungal resistance as well as the advent of new antifungal drugs has generated a renewed interest in fungal susceptibility testing. We used a previously described disk diffusion method to evaluate the susceptibility profile of a large collection of recent clinical Candida spp. isolates against fluconazole. A total of 1,784 yeast isolates were tested, including the following species: Candida albicans (1,036), C. tropicalis (279), C. parapsilosis (202), C. glabrata (119), C. guilliermondii (90), C. krusei (32), C. lusitaniae (7), Candida spp. (14) and other yeasts (5). Susceptibility ranking to fluconazole obtained with all yeasts tested was: C. parapsilosis <FONT FACE=Symbol>@</FONT> C. tropicalis <FONT... |

| Declining incidence of oropharyngeal candidosis and opportunistic infections over recent years can be attributed to the use of highly active anti-retroviral therapy (HAART). Infection with C. albicans generally involves adherence and colonization of superficial tissues. During this process, budding yeasts are able to transform to hyphae and penetrate into the deep tissue. Using the biocell tracer system, C. albicans hyphal growth was dynamically observed at the cellular level. Ritonavir was effective in the inhibition of hyphal growth with growth rate of 0.8 mum/min. This study showed the in vitro effect of HIV anti-retroviral drug on the growth rate of the C. albicans hyphae. |

| 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.... |
