Ashford University Mucorales Disease Presentation I’ve attached the rubric and example of what the powerpoint should look like. Must be due before 11:59 PST Minimum of 8 slides Disease Presentation Rubric
Assignment: Create a presentation and an outline (summary) of presentation
Topic: Choose a disease organism/group of organisms or a disease that interests you.
Try not to duplicate the diseases/organisms that were covered in the lectures.
Content: Describe the organism(s), describe the disease (symptoms), Outline the chain
of transmission for the disease if applicable, describe how the organism causes the
disease (what are the virulence factors), what are the treatments for the disease
Specifics: The presentation should be a minimum of 8 slides. You must also create a
bibliography listing your sources. The outline should be a bullet-point list of the facts
that you would have said if you gave the presentation in class.
An example of a “A” presentation is also attached. It was created by a former student.

Where oh where can these pathogens be…
What if someone told you that the normal microorganisms living on your skin or in
your immediate surrounding environment could one day cause a disease or severe
illness? During this presentation you will hear about pathogenic Staphylococcus and
Streptococcus species that can do so if your immune system becomes compromised
and you come in contact with these bacteria. Along with discussing morphology and
arrangement, I will point out any key virulence factors and what diseases each
bacterium causes. I will discuss possible treatment or prevention methods for each of
the Gram-positive cocci as well.
Staphylococcus
Staphylococcus aureus
-Bacteria usually carried in nasal cavity
-Gram-positive, clustered cocci
-Opportunistic bacteria and often affects people in
the hospital setting or those with chronic illnesses

Staphylococcus aureus
-Staphylococcus aureus is one of the most
common causes of skin, soft-tissue, and
nosocomial infection
-Can cause illnesses such as MRSA which
circulates in a hospital setting when patients have
a weakened immune system
-Hosts include humans and wild/domesticated
animals
-Antibiotics such as cloxacillin and cephalexin are
commonly used to treat staph infections.
Vancomycin is used to treat MRSA
Staphylococcus
Staphylococcus haemolytıcus
-Gram-positive, clustered cocci
-Opportunistic bacteria and often affects people in
the hospital setting or those with chronic illnesses
-Infections usually occur in patients with the
insertion of medical devices

Staphylococcus haemolytıcus
-Part of skin flora and is usually located under
the arms and in the groin area
-The ability to adhere to medical devices and
subsequently form biofilms is a major virulence
factor
-Causes Peritonitis, which is the inflammation of
the serous membrane lining abdominal cavity
-Most strains are antibiotic resistant due to the
production of biofilms
Streptococcus
Streptococcus equısımılıs
-Gram-positive, pair or chain-linked cocci
-Emerging pathogenic bacteria found in tropical
climates
-Usually found on animal skin or on the skin,
blood cultures, throat, and genital tract of humans

Streptococcus equısımılıs
-Usually found on animal skin surfaces, but
because hygiene isn’t conducted it can be
transmitted by direct contact
-Can cause Meningitis in humans
-Key virulence factors include often encapsulated
and resistant to the phagocytosis process
-Meningitis can be prevented with a vaccination
in early childhood, and in acute cases, treated
with antibiotics
Streptococcus
Streptococcus pyogenes
-Gram-positive, chain-linked cocci
-Belongs to Group A Streptococcus
-Human infections tend to begin in the throat or
on the skin
http://thewatchers.us/necrotizing_fasciitis.html
Streptococcus pyogenes
-Streptococcal infection produces small zones of
beta-hemolysis, a complete destruction of red
blood cells
-Has significant virulence factors including the
ability to excrete toxins.
-Necrotizing fasciitis is caused by the bacteria
when it is able to penetrate deep into the skin
-The removal of infected tissue is treatment for
Necrotizing fasciitis, but sometimes amputation is
the only solution
