To quantitatively assess the role of Candida species in antibiotic-associated diarrhea (AAD), stool samples from a total of 395 patients and control subjects were cultured in differential isolation medium: 98 patients had AAD, 93 patients were taking antibiotics but did not have diarrhea (A(+)D(-)), 97 patients were not taking antibiotics but had diarrhea (A(-)D(+)), and 107 patients were contr...

Candida albicans is strongly associated with severe early childhood caries (S-ECC). However, the roles of secreted aspartyl proteinases (Saps), an important virulence factor of C. albicans, in the progress of S-ECC are not clear. In our study, the Saps activities were evaluated by the yeast nitrogen base-bovine serum albumi (YNB-BSA) agar plate method and by the MTT method with bovine serum alb...

Oral candidosis is a common problem in immunocompromised patients, and whilst Candida albicans is regarded as the principal cause of infection, other non-Candida albicans Candida (NCAC) species are increasingly being recognized as human pathogens. Relatively little is known about the virulence factors associated with NCAC species, and the aim of this study was to use a reconstituted human oral ...

Candida virulence attributes include the ability to colonize and invade host tissues, and the secretion of hydrolytic enzymes. Although Candida albicans is regarded as the principal fungi causing infections in humans, other species, particularly Candida tropicalis, are increasingly being recognized as human pathogens. Relatively little is known, however, about the virulence attributes associate...

Candida albicans (C. albicans) is one of the important opportunistic fungal pathogens that is closely associated with disseminated or chronic infections. The objective of this study is to evaluate the synergistic antifungal effect of licofelone, which is dual microsomal prostaglandin E2 synthase/lipoxygenase (mPGES-1/LOX) inhibitor in combination with fluconazole against C. albicans. Here our r...

Macrophage elastase was purified from tissue-culture medium conditioned by inflammatory mouse peritoneal macrophages. Characterized as a secreted neutral metalloproteinase, this enzyme was shown to be catalytically and immunochemically distinct from the mouse pancreatic and mouse granulocyte elastases, both of which are serine proteinases. Inhibition profiles, production of nascent N-terminal l...

Truncation of al-proteinase inhibitor prior to Pros0' prevents its secretion. This residue is the carboxyl terminus of a highly conserved sequence in serpins, suggesting that either Pros0' or the conserved sequence may serve as at least a part of a signal recognized by components of the secretory pathway. To evaluate these possibilities, we have determined the effects of replacement of ProS0' o...
