Eukaryote

Rhizopus spp.

Gram Negative, filamentous fungal hyphae. Commonly found in soil and decaying matter; can cause mucormycosis in immunocompromised individuals.

Penicillium spp.

Gram Positive, filamentous with branched hyphae. Important for antibiotic production (e.g., penicillin); also used in food industry for cheese production and can cause allergic reactions in some.

Aspergillus spp.

Gram Positive, filamentous with conidiophores. Responsible for producing aflatoxins, potent carcinogens; significant in causing respiratory infections and aspergillosis, particularly in immunocompromised patients.

Trichophyton rubrum

Gram Positive, filamentous dermatophyte. Leading cause of dermatophyte infections, leading to conditions like athlete's foot and nail infections.

Histoplasma capsulatum

Gram Negative, yeast form in tissues; filamentous in culture. Causes histoplasmosis, a respiratory disease linked to bird and bat droppings; important in public health as it impacts individuals in endemic areas.

Coccidioides immitis

Gram Negative, forms spherules with large round structures containing endospores. Causes coccidioidomycosis (Valley fever), an important respiratory disease, especially in certain geographic regions.

Necator americanus

Gram Negative, hookworm with elongated cylindrical shape. One of the hookworms that can cause anemia and malnutrition, particularly in developing countries.

Giardia lamblia

Gram Negative, teardrop-shaped with flagella (trophozoite) and oval cyst form. Major cause of gastrointestinal infections (giardiasis); significant public health concern due to transmission through contaminated water.

Enterobius vermicularis

Gram Negative, elongated pinworm; oval eggs. Commonly known as pinworm; significant in hygiene studies, especially in children.

Plasmodium falciparum

Gram Negative, crescent-shaped in blood (gametocytes); ring stages in red blood cells. Most lethal species of malaria parasite; significant global health issue with severe morbidity and mortality.

Trypanosoma brucei

Gram Negative, elongated and wavy, flagellated protozoan. Causes African sleeping sickness, impacting agricultural and rural populations in Africa; prevention and treatment require significant health resources.
