Do antibiotics work on protists?

antibiotics target certain types of
bacteria; antifungals target certain fungi; antiparasitics target specific types of protists (eg antimalarials target Plasmodium, the protist that causes malaria); and antivirals inhibit the …
What disease are protists involved in?
For example, protist parasites include the causative agents of
malaria
, African sleeping sickness, amoebic encephalitis, and waterborne gastroenteritis in humans. Other protist pathogens prey on plants, effecting massive destruction of food crops.
How do protists cause harm?

Is protist a living thing?
All living organisms can be broadly divided into two groups — prokaryotes and eukaryotes — which are distinguished by the relative complexity of their cells. … Bacteria and archaea are prokaryotes, while all other
living
organisms — protists, plants, animals and fungi — are eukaryotes.
What does a protist do?
Plant-like protists
produce almost one-half of the oxygen on the planet through photosynthesis
. Other protists decompose and recycle nutrients that humans need to live. All protists make up a huge part of the food chain.
Are protists bacteria?
The primary difference between them is their cellular organization.
Bacteria are single-celled microbes
and are prokaryotes, which means they’re single-celled organisms lacking specialized organelles. … In contrast, protists are mostly single-celled eukaryotic organisms that are not plants, fungi, or animals.
Why are protozoa so hard to treat?
Because fungi, protozoa, and helminths are eukaryotic, their cells are very similar to human cells, making it
more difficult to develop drugs with selective toxicity
.
Why is it difficult to treat protozoan infections?
Protozoa may have complex
life
-cycles, infections are typically difficult to treat and in most cases prophylactic immunization is ineffective. One redeeming feature is that the organisms are large enough to be seen in stool, other tissue fluids and histologic sections in many cases.

of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista

food or water that has been contaminated by feces of infected people or animals

Is athlete’s foot caused by protists?
Athlete’s foot is caused by
fungi
that normally live on the skin, hair, and nails called dermatophytes
How do protists reproduce?
Protists reproduce by a variety of mechanisms. Most undergo some form of asexual reproduction, such as
binary fission
, to produce two daughter cells. In protists, binary fission can be divided into transverse or longitudinal, depending on the axis of orientation; sometimes Paramecium exhibits this method.
