What type of morphology can be seen in Penicillium?

Morphological Description: In Penicillium, phialides may be produced singly, in groups or from branched metulae, giving a brush-like appearance (a penicillus). The penicillus may contain both branches and metulae (penultimate branches which bear a whorl of phialides).

What is the morphology of Candida infection?

It is generally referred to as a dimorphic fungus since it grows both as yeast and filamentous cells. However, it has several different morphological phenotypes including opaque, GUT, and pseudohyphal forms. C….

How can we identify the fungus Penicillium?

Important characters used for describing Penicillium include colony texture, degree of sporulation, the colour of conidia, the abundance, texture and colour of mycelia, the presence and colours of soluble pigments and exudates, colony reverse colours, and degree of growth and acid production (in some species acid …

How do you find Penicillium under a microscope?

They possess simple or branching structures that are slightly elongated and end in clusters of flask-shapes known as phialides and are called conidiophores. The spores also are known as conidia. They are manufactured or produced in dry chains and they emanate from the tips of the phialides.

What kind of hyphae does Candida parapsilosis form?

Candida parapsilosis does not form true hyphae; it exists in either a yeast phase or pseudohyphal form. It is white, creamy, and shiny in dextrose agar and its cell shape is oval, round, or cylindrical.

Can a Candida parapsilosis infection be life threatening?

Candida parapsilosis infection can be life-threatening and is more common in people with wounds and those who are hospitalized. This infection also affects infants who are not yet developed.

What kind of agar is used for Candida parapsilosis?

Sabouraud dextrose agar Candida parapsilosis produces white, creamy, shiny, and smooth or wrinkled colonies. Cornmeal agar is used to identify C andida parapsilosis pseudohyphae. Figure: Candida parapsilosis – Pink colored colonies on Hicrome agar.

Why is biofilm important for Candida parapsilosis?

Adhesion capacity and biofilm are important for C. parapsilosis, because C. parapilosis infection is mostly due to the use of in-dwelling devices. Adhesion capacity is the ability of fungus to adhere to other organisms’ cells or tissue, especially mucosal surfaces, which is required for initial colonization.
