The invention relates to the identification and disruption of essential fungal specific genes isolated in the yeast pathogen Candida albicans namely CaKRE5, CaALR1, and CaCDC24 and to the use thereof in antifungal diagnosis and as essential antifungal targets in a fungal species for antifungal drug discovery. In one embodiment an ion exclusion adsorption mechanism is used for the separation process. A user request associated with a feature presented in the first pull down menu is monitored. The tailcap assembly also includes switches adapted to provide signals to the lighting control circuitry in response to pivot movement and vertical movement of the joystick. Along each of such sides of the non-flame-hole portions as are adjacent to each of the collective flame-hole portions, outside flame holes are formed at a predetermined spacing therebetween in a longitudinal direction of the non-flame-hole portions. 8 or higher, which is suited for mixing with resin material to form a compound.
