Dalmau method is used to identify what yeast?
-
C. glabrata
-
C. tropiclis
-
C. albican
-
C. krusei
Correct Answer
A. C. albicanExplanation
Dalmau method is used to identify the yeast species Candida albicans. This method involves inoculating the yeast onto a specific agar medium and observing its growth characteristics, such as colony morphology and color. By analyzing these characteristics, microbiologists can differentiate C. albicans from other Candida species, such as C. glabrata, C. tropicalis, and C. krusei. Therefore, the correct answer is C. albicans.Rate this question:

What yeast has cluster or pairs chlamydospores?
-
C. guilliermondii
-
C. dubliniensis
-
C. neoformans
-
C. kefyr
Correct Answer
A. C. dubliniensisExplanation
C. dubliniensis is the correct answer because it is known to have cluster or pairs of chlamydospores. Chlamydospores are a type of asexual spore that are commonly found in certain species of yeast. C. dubliniensis is a pathogenic yeast species that is closely related to Candida albicans, and it is often associated with oral infections in immunocompromised individuals.Rate this question:

What term is used to describe yeast cell that is rectangular or barrel shaped, thick or thin walled, depending on the genus?
-
Blastoconidia
-
Chlamydoconidia
-
Ascospore
-
Arthroconidia
Correct Answer
A. ArthroconidiaExplanation
Arthroconidia are the term used to describe yeast cells that are rectangular or barrel-shaped, with thick or thin walls, depending on the genus. Blastoconidia refers to a type of yeast cell that reproduces by budding, chlamydoconidia are thick-walled, round or oval-shaped cells, and ascospores are sexual spores produced by fungi. Therefore, arthroconidia best fits the description given in the question.Rate this question:

What term is used to describe structure that septate or aseptate filament of a fungus, many together compose the mycelium?
-
Hyphae
-
Psedohyphae
-
Ascus
-
Ascospore
Correct Answer
A. HyphaeExplanation
Hyphae is the correct answer because it is the term used to describe the structure that septate or aseptate filaments of a fungus, which together compose the mycelium. Hyphae are the branching, thread-like structures that make up the body of a fungus and are responsible for absorbing nutrients and facilitating growth.Rate this question:

What yeast has Kinyoun stain (acid fast) positive?
-
Rhodotorula
-
Saccharomyces cerevisiae
-
Geotrichum
-
C. albican
Correct Answer
A. Saccharomyces cerevisiaeExplanation
Saccharomyces cerevisiae is the correct answer because it is a type of yeast that is Kinyoun stain (acid fast) positive. This means that when stained with Kinyoun stain, Saccharomyces cerevisiae will retain the stain and appear red under a microscope. The other options, Rhodotorula, Geotrichum, and C. albican, do not exhibit acid fast staining and would not retain the stain when subjected to the Kinyoun staining technique.Rate this question:
