ADHESION AND BIOFILM FORMATION ABILITY BY CLINICAL URINARY
Candida spp are now responsible for approximately 10% of urinary tract infections in hospitalized patients. In contrast to vaginal candidiasis, approximately 50% of urinary isolates of Candida are of Non-Candida albicans Candida (NCAC) spp, the most common of which are C.glabrata, C. tropicalis and C. parapsilosis spp. This has been attributed

Candida spp. in periodontal disease: a brief review
Virulence factors of Candida spp. Candida albicans is frequently found in humans, and often resides on skin, mucosa, and normal gingival sulcus of otherwise healthy individuals. In compromised hosts, however, Candida albicans can cause serious disease, ranging from deep-seated mucosal infection to systemic infections (1,13).

Virulence of Clinical Candida Isolates
Apr 12, 2021 Selected virulence factors of Candida spp. Other virulence factors produced by Candida spp. are extracellular enzymes, responsi-ble for tissue adhesion and penetration and thus host invasion. Four different classes of hydrolases (proteases, phospholipases, lipases, and hemolysins) have been so far identiﬁed in Candida spp. .

Nevertheless, after 24 h, C. glabrata extent of adhesion was still higher than C. tropicalis and C. parapsilosis. This particular behavior of C. glabrata was also observed after 2 h of adhesion, showing a higher number of adhered cells in comparison with the other NCAC spp, which behaved very similarly.

Virulence Traits Contributing to Pathogenicity of Candida Species
Adhesion helps Candida cells to penetrate, disseminate and persist in host tissues . Similar to other microbial pathogens, adhesion in Candida spp. is initiated and controlled by several cell-signaling cascades. The process of adherence to host cell is initiated by non-specific factors like hydrophobicity and electrostatic forces and further
