Microorganisms and Parasites Quiz

Unicellular organisms lacking a nucleus (prokaryotic) that reproduce through binary fission.

Cell wall structure lacking peptidoglycans, thriving in extreme environments, like very hot, cold, salty, or methane-rich habitats.

Classifying bacteria based on their response to staining with a dye.

Classifying bacteria based on their oxygen requirements; some need oxygen, some don't, and some can adapt.

Bacteria categorized based on their energy source, whether they make their own food or rely on external sources.

Unicellular or multicellular eukaryotes, primarily living in water, producing oxygen and carbohydrates crucial for other organisms.

Reproducing through binary fission, budding, or fragmentation.

The red pigment in some Haloarchaea, responsible for their phototropism and the red color of certain lakes.

Fungi that reproduce sexually and asexually, produce fleshy fruiting bodies, and include familiar organisms like mushrooms and Cryptococcus neoformans.

Fungi that reproduce asexually, with their sexual stage unknown, and include species like Candida albicans and Coccidiodes immitis.

Fungal infections that affect the entire body, often acquired through inhalation of fungal spores.

Fungal infections primarily caused by dimorphic fungi, commonly found in specific geographical regions.

Fungal infections that enter the body through wounds, remain localized, and are often found in soil.

Fungal infections that invade the skin, hair, and nails.

Fungal infections that affect the superficial layers of skin and hair, causing mostly cosmetic concerns.

Fungal infections that affect primarily immunocompromised individuals, often caused by common fungi with low virulence.

Unicellular eukaryotic organisms with a nucleus and complex organelles, obtaining nutrients through absorption or ingestion.

Protozoa that move by whipping their whip-like structures. Example: Giardia Lamblia.

Protozoa that use tiny hair-like structures (cilia) to move. Example: Balantidium coli.

Protozoa that move by extending temporary projections called pseudopodia. Example: Entamoeba histolytica.

Protozoa without any means of self-propelling movement. Example: Plasmodium falciparum.

Multicellular organisms without a nucleus (prokaryotic) specialized for saprophytic and parasitic life in damp and moist conditions. They grow filamentous structures (hyphae) and reproduce through spores.

Fungi that reproduce sexually by forming zygospores and asexually by forming sporangiospores. Examples: Rhizopus spp. (Black bread mold).

Fungi that reproduce sexually by forming ascospores inside asci and asexually by forming conidiophores. Examples: Microsporum spp. (causative agent of ringworm), Penicillium spp.

Multicellular eukaryotic parasites that are bilaterally symmetrical, elongated, tapered at both ends, nonsegmented, and white. They have an anterior mouth and posterior anus, separate sexes (females are larger) and are found in animals, plants, and various environments.

Multicellular eukaryotic parasites that are parasitic in all stages of their life cycle. They are often long, segmented, flattened dorsoventrally, and tape-like. They have a scolex head with suckers and sometimes hooks for attachment to organs and their size can range from a few millimeters to several meters. They live in the small intestine of humans and animals.

A classification system placing viruses into seven groups based on nucleic acid type, strandedness, sense, and replication method.

Viruses with double-stranded DNA (dsDNA).

Dorso-ventrally flattened, leaf-like, unsegmented worms with a tegument covering. They have two suckers (oral and ventral) and blind intestinal tracts. Most species are hermaphrodites except for Schistosoma spp.

The anterior end of a cestode (tapeworm), which is responsible for attaching to the host's intestinal lining. It typically contains suckers and sometimes hooks for attachment.

Viruses with single-stranded DNA (ssDNA).

Individual segments or units that make up the body of a cestode (tapeworm). They contain reproductive organs and detach from the body to release fertilized eggs.

Viruses with double-stranded RNA (dsRNA).

Viruses with single-stranded RNA (+ strand or sense).

Viruses with single-stranded RNA (- strand or antisense).

Viruses with single-stranded RNA that use reverse transcriptase (RT) to make DNA.

Viruses with double-stranded DNA (dsDNA) that use reverse transcriptase (RT) to make RNA.
