Adherence of yeasts to other microorganisms and epithelial cell surfaces is important in their colonization. Comparative studies based on the coaggregation of Candida dubliniensis versus Candida albicans with Fusobacterium nucleatum and other oral bacteria suggested differences in the surfaces of these yeasts. Transmission electron microscopy was used to test the hypothesis that there are morphologic variations in the cell surface of these two species.

Fresh noma is a severe orofacial necrosis with an astonishingly rapid development. It is seen mainly in malnourished children less than 4 years old from developing countries. Cytokines play a central role in oral mucosal inflammation.

Microbial adherence to mucosal surfaces is an important first step in the initiation of the pathogenic process in the oral cavity. Candida albicans, the most adherent and pathogenic Candida species, utilizes a variety of mechanisms to adhere to human tissues. Although the strongest mechanism of adherence involves mannoprotein adhesins on C.

Candida species, including the novel opportunistic pathogen Candida dubliniensis, are now emerging as major agents of nosocomial infections. Many such manifestations of infections associated with the formation of Candida biofilms include those occurring on devices such as indwelling intravascular catheters. Fungal biofilm-associated infections are frequently refractory to conventional therapy because of resistance to antimicrobial agents.
