.2% of Candida isolates tested were susceptible (S) to fluconazole; however, 13 of 31 species identified exhibited decreased susceptibility (<75% S), similar to that seen with the resistant (R) species C. glabrata and C. krusei. Among 197,619 isolates of Candida spp. tested against voriconazole, 95.0% were S and 3% were R. About 30% of fluconazole-R isolates of C. albicans, C. glabrata, C. tropicalis, C. rugosa, C. lipolytica, C. pelliculosa, C. apicola, C. haemulonii, C. humicola, C. lambica, and C. ciferrii remained S to voriconazole. An increase in fluconazole resistance over time was seen with C. parapsilosis, C. guilliermondii, C. lusitaniae, C. sake, and C. pelliculosa. Among the emerging fluconazole-R species were C. guilliermondii (11.4% R), C. inconspicua (53.2% R), C. rugosa (41.8% R), and C. norvegensis (40.7% R). The rates of isolation of C. rugosa, C. inconspicua, and C. norvegensis increased by 5-to 10-fold over the 10.5-year study period. C. guilliermondii and C. rugosa were most prominent in Latin America, whereas C. inconspicua and C. norvegensis were most common in Eastern European countries. This survey identifies several less-common species of Candida with decreased susceptibility to azoles. These organisms may pose a future threat to optimal antifungal therapy and underscore the importance of prompt and accurate species identification and antifungal susceptibility testing.Antifungal susceptibility testing is playing an increasing role as a means to track the development of antifungal resistance in epidemiological studies (2, 10, 12, 17, 27, 45-47, 55, 63). One of the important by-products of the standardization of antifungal susceptibility testing has been the ability to conduct surveillance for antifungal resistance using uniform methods (44). Meaningful large-scale surveys of antifungal susceptibility and resistance conducted over time would not be possible without a standardized broth microdilution (BMD) or disk diffusion (DD) method for performing the in vitro studies (12,38,60). Global surveillance programs such as the ARTEMIS antifungal surveillance program for DD testing (49,57,60) and MIC testing (12, 13), the European Confederation of Medical Mycology (ECMM) survey of candidemia (68), and the SENTRY Antifungal Surveillance Program (36-38) promote the use of standardized DD and BMD methods and provide useful and consistent antifungal susceptibility data from a broad international network of hospitals and laboratories.The ARTEMIS global antifungal surveillance program is among the most comprehensive and long-running fungal surveillance programs (12,45,57,58,60). The ARTEMIS program was designed to address many of the potential limitations of resistance surveillance studies (26): (i) it is both longitudinal (1997 to present) and global (142 participating sites in 41 countries) in scope, (ii) it employs standardized DD (7) and BMD (9) antifungal susceptibility test methods, (iii) both internal quality control (QC) performed in each participating laboratory and external quality assurance...

Aims:  The in vitro activity of some essential oils (EO) (thyme red, fennel, clove, pine, sage, lemon balm and lavender) against clinical and environmental fungal strains was determined. Methods and Results:  The minimal inhibitory concentrations were determined by a microdilution method in RPMI 1640 and by a vapour contact assay. The composition of oils was analysed by gas chromatography (GC) and GC/mass spectrometry. The results indicated that the oils antifungal activity depended on the experimental assay used. The inhibiting effects of EO in vapour phase were generally higher than those in liquid state. According to both methods thyme red and clove were found to be the oils with the widest spectrum of activity against all fungi tested. Conclusions:  Despite the differences between the two methods, our results demonstrate that some EO are very active on dermatophytes and dematiaceous fungi. However, more data will be necessary to confirm this good in vitro efficacy. Significance and Impact of the Study:  This study could identify candidates of EO for developing alternative methods to control environmental and clinically undesirable filamentous fungi.

Intestinal colonization by lactobacilli is suggested to be a prerequisite to normal mucosal immune functions. An inadequate level of lactobacilli may be involved in appearance of allergic disease of which, infantile colic, is often considered an early clinical manifestation. The aim of the study is to evaluate intestinal lactobacilli in breast-fed infants with infantile colic and healthy infants. Fifty-six breast-fed infants, aged 15-60 days were enrolled in the study and divided into two groups: colicky (30 cases) and healthy (26 cases) according to Wessel's criteria. Stool samples were collected, diluted and cultured on selective media. The colonies were counted, reported as colony forming unit (cfu) per gram of faeces and identified by biochemical methods. Different colonization patterns of lactobacilli were found among colicky and healthy infants. Lactobacillus brevis (4.34 x 10(8) cfu/g) and L. lactis lactis (2.51 x 10(7) cfu/g) were found only in colicky infants while L. acidophilus (2.41 x 10(7) cfu/g) was found only in healthy infants. Lactobacillus brevis and L. lactis lactis might be involved in the pathogenesis of infantile colic increasing meteorism and abdominal distension. Further studies are required to understand how the observed differences may be involved in the pathogenesis of this common disorder.

Our findings showed that gut microbiota was significantly modified after 5 days of antibiotic therapy; exclusively, breast-feeding may be relevant in promoting the re-establishment of gut microbiota composition in early infancy.
