Classification, Diagnostics & Microbial Diversity

These flashcards cover key concepts related to microbial diversity, diagnostics, and the classification of microorganisms as presented in the lecture notes.

What are the two main phyla of Gram-Positive bacteria?

Firmicutes (Low G+C) and Actinobacteria (High G+C)

What are the two phyla of Archaea?

Crenarchaeota (Hyperthermophiles) and Euryarcheota (Methanogens and Halophiles)

What differentiates yeasts from molds in the Kingdom Fungi?

Yeasts are single-celled, while molds are multicellular and filamentous.

What are some diseases caused by fungi?

Allergic reactions, infections (mycoses), and production of toxic compounds (mycotoxins).

What are the two life forms of Protozoa?

Trophozoite (active form) and Cyst (dormant form).

What are the four classifications of Protozoa based on their movement?

Flagellated, Amoeboid, Sporozoan, and Ciliated.

What are the two main phyla of worms in the Kingdom Animalia?

Platyhelminthes (flatworms) and Nematodes (roundworms).

Which class of Arthropoda acts as biological vectors for pathogens?

Mites, Ticks, and Insects.

What are the main structural components of a virus?

Nucleic Acid, Capsid, and sometimes an Envelope.

What are the key steps in the virus life cycle?

Attachment, Penetration, Biosynthesis, Assembly, Maturation.

What properties are used to classify viruses?

Genetic information, envelope status, size, and capsid symmetry.

What is the definition of a prion?

A non-living infectious agent composed mainly of protein, known for causing neurodegenerative diseases.

What does the term 'tropism' refer to in the context of viral infections?

The viruses pickiness when infecting particular cell types.
