We have looked into the taxonomy around what makes a bacteria a bacteria and not a protist!! Now it is time to look into a few different types of each of these so that you have a bettter understanding of them.
Bacteria
The Internet has become a valuable resource in doing research. Not only can you find articles by scientists and other notable researchers but you can also find news articles that explain the science. In this assignment you are going to explore the Internet in an effort to find out more about bacteria.
Your Assignment
- Using the Internet find three sources for information about five bacteria (at least one from Archaebacteria and Eubacteria). Also one must be a bacteria that HELPS us somehow – that benefits humans in some way.
- Create a table like the one below to present your research.
Bacteria name (give binomial nomenclature) Three sources with website addresses General characteristics Impact on human health or the environment Other interesting facts
Protists
Protists are an interesting kingdom of organisms. Many are useful and do not pose a risk to human health. But, there are others that can cause severe illnesses. In fact, there are branches of medicine that focus on the diseases caused by protists.
In this assignment you will examine the branches of medicine that deal with protists. At the same time you might consider these as a profession you may want to pursue. You will also research a number of medical conditions caused by these protists.
Your Assignment
- Using the Internet research and describe the professions that focus on pathogenic protozoans. The professions you are to research are:
- Doctor of tropical medicine
- Microbiologist
- Doctor of infectious diseases
- Using the Internet find three sources for information about five pathogenic protozoans. Create a table like the one below to present your research.
Protozoan name (give binomial nomenclature) Three sources with website addresses General characteristics of the organism Impact on human health as well as symptoms they cause Other interesting facts
Bacteria name (give binomial nomenclature)
Coccus
Bacillus
thermoacidophiles
Cyanobacteria
Mycoplasma

General characteristics:
Coccus : Staphylococcus and Streptococcus are the most common bacteria in this group and usually are Gram-positive. These bacteria perform useful functions in the body and environment but they can be harmful.
Bacillus: rod shaped bacteria that are usually Gram-positive or negative.
thermoacidophiles: These bacteria are found in extremely acidic conditions and in areas with very high temperatures
Cyanobacteria: photo synthetic like plants use sun to make food. thought to be the second organisms in existence, because they give off oxygen as a byproductthey are found in the water and were once thought to be blue-green algae.
Mycoplasma: because of the absence of cell wall, Mycoplasma can be bacilli or cocci form of bacteria. As such, they are unaffected by antiobiotics, which work by targeting and damaging the cell wall
Impact on human health or the environment:
Coccus : Staphylococcus aureus can cause impetigo (skin infection), scalded skin syndrome and food poisoning, while Streptococcus pyogenes may cause tonsillitis and strep throat.
Bacillus: E. coli and Salmonella are the most commonly encountered species responsible for food poisoning and typhoid fever, bacillus also includes two of the most dangerous bacteria known, that is Bacillus anthracis, which causes the lung disease anthrax, and Clostridium, which causes botulism, gangrene and tetanus.
Cyanobacteria: responsible for a variety of health effects in humans, from skin rashes to gastrointestinal, respiratory and allergic reactions.
Mycoplasma: Mycoplasma pneumonia causes respiratory disease, whereas Mycoplasma genitalium is responsible for pelvic disease
Tropical medicine is the branch of medicine that deals with health problems that occur uniquely, are more widespread, or prove more difficult to control in tropical and subtropical regions.
A microbiologist is a scientist who works in the field of microbiology. Microbiologists study organisms called microbes. Microbes can take the form of bacteria, viruses, fungi, and protists. One of the microbiologists main research aim is to find out how microbes affect the world around them.
Infectious disease doctors are internal medicine doctors who treat and diagnose infectious diseases of varying types in the human body. Some diseases that infectious disease doctors deal with include AIDS, tuberculosis, malaria, meningitis, tetanus, and various infections of the respiratory system. Infectious disease doctors also aid in the prevention of tropical and other travel-related diseases.
Chart Part:
Dientamoeba fragilis Is an intestinal form causing infections.It is not common.
Endamoeba hartmanii Is a small ameba which may live in the intestines producing subclinical or mild infections.

One of the major causes of illness and contributors to mortality in tropical and sub-tropical countries is malaria. The cause of malaria is an intracellular parasite Plasmodium species.
Plasmodium parasites multiply in the liver before infecting the red blood cells of their host. Outside of tropical areas, the morphological similar parasites
Toxoplasma gondii the cause of toxoplasmosis. This extremely common parasite occurs worldwide and is capable of causing infection in many different animals.
