Diagnosis and Treatment
100

This bacterium is responsible for toxic shock syndrome and scalded skin syndrome.

Staphylococcus aureus

100

This bacterium causes Strep throat and can lead to rheumatic fever if untreated.

Streptococcus pyogenes

100

This bacterium is the most common cause of peptic ulcers.

Helicobacter pylori

100

This bacterium causes plague and is transmitted by fleas.

Yersinia pestis

100

This staining technique is often used to quickly detect Neisseria meningitidis in CSF.

Gram stain

200

The parasite Acanthamoeba can cause this serious eye infection, often linked to contact lens use.

Keratitis

200

The three types of this virus are A, B, and C; one type is responsible for pandemics.

Influenza virus (Influenza A causes pandemics)

200

This highly contagious virus is often associated with cruise ship outbreaks of diarrhea and vomiting.

Norovirus

200

This retrovirus weakens the immune system by destroying CD4+ T cells.

HIV (human immunodeficiency virus)

200

This diagnostic method is used to confirm the presence of influenza or COVID-19 genetic material.

PCR testing (Polymerase chain reaction testing)

300

This virus causes cold sores around the mouth

HSV-1 (Herpes Simplex Virus-1)

300

This fungus can cause opportunistic pneumonia in immunocompromised patients, especially those with HIV/AIDS.

Pneumocystis jirovecii

300

This protozoan causes amebic dysentery.

Entamoeba histolytica

300

This bacterium causes syphilis.

Treponema pallidum

300

Proper antibiotic stewardship is the best prevention against this opportunistic GI infection.

C. diff

400

This bacterium is often associated with foodborne illness from improperly canned foods.

Clostridium botulinum

400

A grayish pseudomembrane in the throat is associated with this disease.

Diphtheria

400

This condition results from ingestion of toxins, not the organisms themselves, as in Staphylococcus aureus food poisoning.

Intoxication

400

This infection is the most commonly reported bacterial STI in the United States.

Chlamydia trachomatis

400

Mosquito nets and insect repellent are crucial preventive measures against this parasitic disease.

Malaria

500

This protozoan parasite, transmitted by cats, can cause congenital nervous system damage.

Toxoplasma gondii

500

Annual vaccination is recommended for this virus due to frequent antigenic drift.

Influenza virus

500

“Rice-water” stool is associated with infection by this bacterium.

Vibrio cholerae

500

Koplik spots and a maculopapular rash are seen in this viral infection that can cause serious complications in immunocompromised patients.

Measles

500
This type of pneumonia should not be treated with antibiotics that target the cell wall. 

Mycoplasma pneumonia (or walking pneumonia) as Mycoplasma pneumoniae does not have cell walls
