KOH test on a vaginal wet mount, showing slings of pseudohyphae of Candida albicans surrounded by round vaginal epithelial cells, conferring a diagnosis of candidal vulvovaginitis. The KOH test , also known as a potassium hydroxide preparation or KOH prep , is a quick, inexpensive fungal test to differentiate dermatophytes and Candida albicans ...
A blastoconidium (plural blastoconidia) is an asexual holoblastic conidia formed through the blowing out or budding process of a yeast cell, which is a type of asexual reproduction that results in a bud arising from a parent cell. [1] [2] The production of a blastoconidium can occur along a true hyphae, pseudohyphae, or a singular yeast cell. [3]
The yeast forms poorly developed pseudohyphae on cornmeal or potato agar. [1] [2] The yeast has been observed to form four hat-shaped ascospores when grown for at least seven days on 5% Difco malt extract agar. [2] The yeast can ferment glucose and cellobiose, but not galactose, sucrose, maltose, lactose, raffinose or trehalose. [1]
The yeast forms branched pseudohyphae on potato agar. The yeast has been observed to form one or two sherical and warty ascospores when grown for at least one week on 5% Difco malt extract agar, and the ascospores are not released from the ascus. [1] The yeast can ferment glucose, but not sucrose, galactose, maltose, lactose, raffinose or ...
Rhodotorula glutinis is an aerobic yeast characterized by pink, smooth colonies with a moist appearance. [2] Reproduction is typically by multipolar budding although pseudohyphae are occasionally produced. Sexual reproduction is by basidiospores arising from a teliospore developed from a mycelial clamp connection. [2]

Pseudohyphae are distinguished from true hyphae by their method of growth, relative frailty and lack of cytoplasmic connection between the cells. Yeasts form pseudohyphae. [ 10 ] They are the result of a sort of incomplete budding where the cells elongate but remain attached after division.
Colonies of C. tropicalis on a Petri dish.. C. tropicalis is a vegetative cell [10] with the shape from round to oval ranging from approximately 2 – 10 micrometers. [3] A mould exhibits dimorphism [8] forming a single-celled yeast or so-called blastoconidia which reproduces by simple budding. [8]
