Pseudomembranous lesions were the most frequent form (54.5%) Forskolin observed by bronchoscopy. Aspergillus fumigatus was the most frequently isolated pathogen (40%). ATB is an uncommon cause

of exacerbation in approximately 5% of critically ill COPD patients admitted to the ICU, and may progress rapidly to IPA with a high mortality rate. Dyspnoea resistant to corticosteroids and appropriate antibiotics with a negative CXR should raise the suspicion of ATB. Early diagnosis of ATB is based on bronchoscopic examination and proven diagnosis maybe safely established with a bronchial mucous biopsy. “
“Biofilm formation is implicated as a potential virulence factor in Candida species and carries important clinical repercussions because of their increased resistance to antifungal treatment, ability

to withstand host defences and to serve as a reservoir for continuing infections. The present study was undertaken to determine the biofilm production among oral Candida isolates from HIV-positive and HIV-negative individuals from Pune, India. Biofilm formation was determined using the spectrophotometric or microtitre plate method in 182 Candida isolates, of which 154 were from HIV-positive and 28 were from HIV-negative individuals. A total of 63.2% of the Candida Kinase Inhibitor Library chemical structure isolates were biofilm producers. Significantly increased biofilm forming abilities both qualitatively as well as quantitatively were observed in Candida isolates from HIV-positive individuals (66.2%) compared to isolates from HIV-negative ones (46.4%), (P– 0.041). Eighty-one (59.6%) C. albicans isolates and 34 (73.9%) non –C. albicans Candida (NCAC) showed biofilm positivity. The NCAC showed significantly greater intensity of biofilm formation compared to the C. albicans, P– 0.032. Our results thus show the enhanced biofilm forming abilities of oral Candida isolates from HIV-infected individuals compared to HIV-uninfected ones and highlight the important role played by biofilm either formation in the pathogenesis of NCAC isolates. “
“There are discrepancies in the retrospective studies published in literature of whether or not bacteraemia could lead to false positivity

of 1,3-β-D (BG) glucan assay. We performed, for the first time, a prospective study evaluating the role of bacterial bloodstream infection to the reactivity of BG assay. Twenty-six episodes of bacteraemia that occurred in high-risk haematological patients were included in our study. Consecutive BG levels >80 pg ml−1 were required for test positivity. Only 2 of 26 patients were BG positive – both with IFDs. Thus, we prospectively did not prove bacteraemia as the source of cross reactivity of BG assay in haematological patients. “
“This in vitro study evaluated different concentrations of chlorhexidine (CHX) solution on the disinfection of dentures colonised with a reference (ATCC 90028) and azole-resistant (R1, R2 e R3) strains of Candida albicans.
