B. False
This question is an excerpt from Nurse Dive's nursing test bank - Fa25 biol Microbiology (Hennepin Technical College) proctored exam. Take the full exam now
Full Explanation
False: While many fungal infections in humans are superficial, such as athlete’s foot and ringworm that affect the skin, fungi are not limited to infecting only the skin. Fungi can cause a wide range of infections, from superficial skin infections to systemic diseases affecting the lungs, bloodstream, and internal organs, especially in immunocompromised individuals.
Similar Questions
Which type of microbial cell divides by budding?
A. Bacteria
Bacteria: Most bacteria reproduce by binary fission, where the cell divides evenly into two identical daughter cells. Budding is not a typical method of bacterial reproduction.
B. Algae
Algae: Algae generally reproduce through binary fission, fragmentation, or sexual reproduction, but budding is not their main reproductive mechanism.
C. Yeast
Yeast: Yeast, a type of fungus, often reproduce by budding, where a small outgrowth develops on the parent cell, enlarges, and eventually separates as a new individual cell.
D. Protozoa
Protozoa: Protozoa usually reproduce by binary fission or multiple fission, with some species reproducing sexually, but they do not reproduce by budding.

Eating undercooked meat can lead to food-borne disease via helminthic infection. What is the common host for Taenia saginata?
A. fish
fish: Fish are a source of other parasitic infections such as Diphyllobothrium latum (fish tapeworm), but they are not the intermediate host for Taenia saginata.
B. ducks
ducks: Ducks may carry parasites and bacteria transmissible to humans, but they are not associated with transmission of Taenia saginata.
C. pigs
pigs: Pigs serve as the intermediate host for Taenia solium (pork tapeworm), not Taenia saginata.
D. cows
cows: Cattle are the intermediate host for Taenia saginata (beef tapeworm). Humans acquire the infection by consuming undercooked or raw beef containing larval cysts.
E. chickens
Chickens can transmit other pathogens such as Salmonella, but they are not involved in the life cycle of Taenia saginata.

Pinworm is a disease caused by species.
A. Escherichia
Escherichia: This bacterial genus includes Escherichia coli, a common cause of urinary tract infections and gastrointestinal illness, but it does not cause pinworm disease.
B. Enterococcus
Enterococcus: These bacteria are part of the normal gut flora and may cause opportunistic infections, but they are not responsible for pinworm infestation.
C. Enterobius
Enterobius: Enterobius vermicularis is the causative agent of pinworm infection, a helminthic disease spread via the fecal–oral route and characterized by perianal itching, especially at night.
D. Entamoeba
Entamoeba: Entamoeba histolytica is a protozoan parasite that causes amoebiasis and dysentery, but it is unrelated to pinworm disease.
