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]
Growth is slightly raised at the center. The yeast forms poorly-developed pseudohyphae on potato agar, or are absent. The yeast has been observed to form one to four, mostly four, hat-shaped ascospores when grown for at least one week on 5% Difco malt extract agar or on potato dextrose agar. When released, the ascospores tend to clump together.
The yeast forms poorly developed pseudohyphae on cornmeal or potato agar. [1] [3] The yeast has been observed to form four hat-shaped ascospores when grown for at least seven days on 5% Difco malt extract agar. [3] The yeast can ferment glucose and cellobiose, but not galactose, sucrose, maltose, lactose, raffinose or trehalose. [1]
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 ...
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 ...
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]
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.
