Patients with weakened immune systems, making them more susceptible to severe infections.

An infection caused by Toxoplasma gondii, leading to multi-organ issues in immunosuppressed patients.

A protozoan parasite causing Toxoplasmosis, can lead to severe symptoms in certain patients.

An intestinal infection caused by Giardia lamblia, often from contaminated water or food.

A urogenital infection caused by Trichomonas vaginalis, characterized by vaginal discharge and odor.

A parasite causing Amoebiasis, leading to intestinal disease and possible abscesses.

An intestinal infection characterized by symptoms like abdominal pain and diarrhea, potentially leading to abscesses.

Severe symptoms may include fever, polmyositis, and encephalitis in susceptible individuals.

Diverse organisms with complex cells containing membranous organelles.

Network of filaments providing shape and support to eukaryotic cells.

Process where eukaryotic cells divide their genetic material into two identical daughter cells.

Spherical-shaped bacteria.

Rod-shaped bacteria.

Spiral or corkscrew-shaped bacteria.

A method to classify bacteria based on their cell wall structure.

Bacteria that form clusters resembling grapes.

Donor cells in E. coli that can transfer DNA to recipient cells.

A genetic sequence necessary for a bacterium to serve as a donor during conjugation.

Hair-like extensions that help donor cells connect with recipient cells during conjugation.

Cytoplasmic connection formed between donor and recipient bacterial cells during conjugation.

A small, circular piece of DNA that can carry extra genes, such as the F factor.

Causative agent of whooping cough; a Gram-negative rod bacterium.

Causative agent of meningococcal meningitis; a Gram-negative diplococcus.

Causative agent of tuberculosis; an acid-fast bacterium.

Caused by Vibrio cholerae; a Gram-negative motile vibro affecting intestines.

Unicellular microorganisms that live in extreme environments; known as archaean.

A rigid virus structure that provides genome protection, found in certain viruses.

Viruses with intricate structures that differ from simple icosahedral and helical forms.

Viruses that specifically infect prokaryotic cells, particularly bacteria.

Viruses containing DNA as genetic material, usually double-stranded.

Viruses that consist of RNA as genetic material, often single-stranded.

The complete virus particle that contains all necessary components to infect host cells.

Criteria to classify viruses based on genome type, replication strategy, and host type.

A virus that attacks the immune system and can lead to AIDS if untreated.

A nucleus enclosed by a membrane found in Eukarya.

Small, circular pieces of DNA, common in Bacteria and Archaea.

Non-coding sections of genes present in Eukarya but rare in others.

Organelles that produce energy, present only in Eukarya.

Microscopic in Eukarya, submicroscopic in Bacteria and Archaea.

A component found in bacterial cell walls, absent in Archaea and Eukarya.

Ribosomes are 70S in Bacteria and Archaea, and 80S in Eukarya.

A process of ammonia oxidation, present in Bacteria and Archaea, absent in Eukarya.

Present in Bacteria and Archaea, but absent in Eukarya; help with buoyancy.

A set of four criteria to determine if a microorganism causes a disease.

The disease-causing microorganisms must always be present in diseased animals, not in healthy ones.

Microorganisms must be isolated from infected animals and cultivated in pure cultures.

Injecting cultured microorganisms into healthy animals should result in the same disease.

Microorganisms must be isolated again from newly infected animals and be the same as the original.

Different pathways through which microorganisms spread.

Spread of disease through tiny droplets in the air when an infected person coughs or sneezes.

Common cold, flu, and pneumonia spread via respiratory droplets.
