Question 14 of 15 This or That? For each disease, choose the agents of infection. Candida albicans FUNGI or BACTERIA

The most common opportunistic fungal infection is due to Candida albicans. When a C. albicans infection is present in the mouth, it is often referred "thrush". Overgrowth of C. albicans in the vagina is known as a "yeast infection".

Question 10 of 15 This or That? For each disease, choose the agents of infection. Haemophilus influenzae BACTERIA or VIRUS

Although the word "influenza" in contained within the name Haemophilus influenzae, H. influenzae is actually a bacterium that was once thought to causes the illness known as the "flu". H. influenzae may cause ear infections and meningitis.

Question 6 of 15 This or That? For each disease, choose the agents of infection. Histoplasma capsulatum FUNGI or PROTOZOA

Histoplasma capsulatum is a fungus endemic to the Ohio Valley. Most individuals exposed to the fungus develop no symptoms.

Question 12 of 15 This or That? For each disease, choose the agents of infection. Staphylococcus aureus VIRUS or BACTERIA

The normal flora of the respiratory tract and the skin contains the bacterium Staphylococcus aureus. S. aureus is responsible for diseases such as impetigo, folliculitis, and necrotizing fasciitis. A methicillin-resistant form of staphylococcus is known as MRSA.

Question 3 of 5 The client is diagnosed with botulism. Identify which aspect of the toxin makes it a reportable disease. The toxin can be dispersed through aerosol and food packaging. The toxin can invade the body through breaches in the skin. Botulinum toxin has therapeutic value to treat muscle spasm. Botulinum toxin has cosmetic value (Botox) to treat facial wrinkles. Botulinum toxin affects the neurological system.

The toxin can be dispersed through aerosol and food packaging.

Question 9 of 15 This or That? For each disease, choose the agents of infection. Trichomonas vaginalis PROTOZOA or FUNGI

Trichomonas vaginalis is a protozoan that is sexually transmitted. T. vaginalis may cause vaginitis in women and urethritis in men.

Question 1 of 15 This or That? For each disease, choose the agents of infection. Varicella zoster VIRUS or PROTOZOA

Varicella zoster is a type of herpesvirus that causes chickenpox in children and young adults. In adults, varicella zoster causes shingles. The virus may remain dormant in the body for years.

Question 3 of 5 The DTaP vaccine protect against ________________. Select all that apply. meningitis diptheria pertussis strep throat tetanus

diptheria pertussis tetanus

Question 1 of 5 The first stage of an infectious disease in which the microbe is present but symptoms have not appeared. incubation prodromal chronic convalescent resolution

incubation

Question 5 of 5 Which is the most devastating protozoal disease worldwide? malaria diphtheria whopping cough pneumonia botulism

malaria

Question 4 of 5 Which organism releases a toxin that causes muscle relaxation? Clostridium botulinum Neisseria meningitides Pneumocystic jirovecii Corynebacterium diphtheriae Plasmodium falciparum

Clostridium botulinum

Question 15 of 15 This or That? For each disease, choose the agents of infection. Giardia lamblia FUNGI or PROTOZOA

Giardia lamblia is a protozoan that infects humans, but also many other mammals including cattle, sheep, and beaver. Exposure to G. lamblia usually occurs by drinking water contaminated with cysts.

Question 2 of 5 An 8-month-old infant has forceful bouts of coughing with an audible whoop. Other clinical presentations include subconjunctival hemorrhage, bulging eyes, and neck vein distention. The child has not been immunized with the diphtheria-tetanus-pertussis vaccine. Which illness is suspected? Diphtheria Infectious mononucleosis Measles Pertussis Strep throat

Petussis

Question 11 of 15 This or That? For each disease, choose the agents of infection. Plasmodium falciparum VIRUS or PROTOZOA

Plasmodium falciparum is responsible for the most devastating protozoal disease in the world, malaria.

Question 5 of 5 Which of the following statements are true? Select all that apply. Pneumocystic jirovecii is a common lung infection. A vaccine is available for protection against pertussis and diphtheria. Clostridium botulinum causes "lockjaw." The MMR vaccine protects against measles, mumps, and the rhinovirus. Respiratory transmission of infectious diseases is most common.

Pneumocystic jirovecii is a common lung infection. A vaccine is available for protection against pertussis and diphtheria. Respiratory transmission of infectious diseases is most common.

Question 2 of 15 This or That? For each disease, choose the agents of infection. Pneumocystis jirovecii PROTOZOA or FUNGI

Pneumocystis jirovecii is an opportunistic fungal infection affecting the pulmonary system. Immunocompromised individuals, such as those suffering from infection by the human immunodeficiency virus, are most at risk for infection by Pneumocystis jirovecii.

Question 5 of 15 This or That? For each disease, choose the agents of infection. Entamoeba histolytica PROTOZOA or BACTERIA

Protozoal infection of the intestines may be caused by Entamoeba histolytica. In most cases, the infection is asymptomatic. However, in some individuals severe damage of the intestinal wall may occur.

Question 4 of 15 This or That? For each disease, choose the agents of infection. Rubella VIRUS or FUNGI

Rubella is a viral infection that is also referred to as the "German measles". Rubella can be transmitted to a developing fetus, resulting in birth defects. Protection against rubella infection is provided by the MMR vaccine.

Question 1 of 5 Which of the following organisms cause infectious diseases in the gastrointestinal tract? Select all that apply. Shigella Borrelia burgdorferi Streptococcus pyogenes Corynebacterium diphtheriae Salmonella

Shigella Salmonella

Question 3 of 15 This or That? For each disease, choose the agents of infection. Vibrio cholerae BACTERIA or VIRUS

The causative agent of cholera is the bacterium, Vibrio cholerae. Cholera is marked by copious amounts of "rice-water" stools. Patients may lose up to 1 liter of fluid per hour as Vibrio cholerae disrupts intestinal absorption.

Question 7 of 15 This or That? For each disease, choose the agents of infection. Clostridium botulinum BACTERIA or FUNGI

The disease botulism is caused by a neurotoxin released by the bacterium Clostridium botulinum. The neurotoxin causes muscle flaccidity and paralysis. The toxin is also used in cosmetic procedures to reduce wrinkling of the skin.
