What is true of Campylobacter jejuni? you may choose more than one
- A.
Causes gastroenteritis
- B.
Is gram positive
- C.
Causes jejunosis
- D.
Has a vibrio structure
Correct Answer(s)
A. Causes gastroenteritis
D. Has a vibrio structureExplanation
Campylobacter jejuni is a bacterium that causes gastroenteritis, an infection of the digestive system characterized by symptoms such as diarrhea, abdominal pain, and fever. It is not gram positive, as it is a gram-negative bacterium. It does not cause jejunosis, which is the inflammation of the jejunum, a part of the small intestine. However, it does have a vibrio structure, referring to its curved or spiral shape resembling the letter "S".Rate this question:

What causes syphilis?
Correct Answer(s)
Treponema pallidum
treponema pallidumExplanation
The correct answer is Treponema pallidum. This bacterium is the main cause of syphilis, a sexually transmitted infection. Treponema pallidum enters the body through direct contact with syphilis sores during sexual activity. It can also be transmitted from an infected mother to her unborn baby. The bacterium spreads through the bloodstream and can affect various organs, leading to a wide range of symptoms if left untreated. Treponema pallidum can be treated with antibiotics, but early detection and prompt treatment are crucial to prevent complications.Rate this question:

What describes the bacterium that causes diphtheria. you may choose more than one.
- A.
Rod shaped
- B.
Caused by Corynebacterium diphtheriae
- C.
Caused by Clostridium diphtheriae
- D.
Gram positive
- E.
Gram negative
Correct Answer(s)
A. Rod shaped
B. Caused by Corynebacterium diphtheriae
D. Gram positiveExplanation
The correct answer is a combination of three statements: rod-shaped, caused by Corynebacterium diphtheriae, and gram-positive. Diphtheria is caused by the bacterium Corynebacterium diphtheriae, which is rod-shaped and stains purple in the Gram stain, indicating that it is gram-positive. Gram-negative bacteria would not be the cause of diphtheria.Rate this question:

Which is false of Francisella tularensis? you may choose more than one.
- A.
Causes tularemia
- B.
It is gram negative
- C.
It is rod shaped
- D.
Causes "rabbit fever"
- E.
It is gram positive
Correct Answer
E. It is gram positiveExplanation
Francisella tularensis is a gram-negative bacterium, not gram-positive. Gram-negative bacteria have a thinner peptidoglycan layer in their cell wall, which does not retain the crystal violet stain used in the Gram staining technique. This bacterium is also known for causing tularemia, a highly infectious disease commonly referred to as "rabbit fever." Additionally, it is rod-shaped, which is a characteristic shape of many bacteria.Rate this question:

Haemophilus ducreyi causes
Correct Answer
chancroid
ChancroidExplanation
Haemophilus ducreyi is a bacterial pathogen that causes chancroid, a sexually transmitted infection. Chancroid is characterized by the development of painful genital ulcers, which can be accompanied by swollen lymph nodes in the groin area. It is primarily transmitted through sexual contact and is more common in regions with poor hygiene and limited access to healthcare. Prompt diagnosis and treatment with antibiotics are essential to prevent complications and further transmission of the infection.Rate this question:

Haemophilus influenzae causes?
- A.
Influenza
- B.
Gastroenteritis
- C.
Meningitis
- D.
Haemophilia
Correct Answer
C. MeningitisExplanation
Haemophilus influenzae is a bacterium that can cause various infections, including meningitis. Meningitis is an inflammation of the protective membranes covering the brain and spinal cord. It can cause symptoms such as severe headache, fever, stiff neck, and sensitivity to light. Haemophilus influenzae type b (Hib) is the most common cause of bacterial meningitis in children under the age of 5. Vaccination against Hib has significantly reduced the incidence of this infection. Therefore, the correct answer is meningitis.Rate this question:

Legionnaires disease is caused by
Correct Answer
Legionella pneumophilia
legionella pneumophiliaExplanation
Legionnaires disease is caused by the bacterium Legionella pneumophila. This bacterium is commonly found in freshwater environments such as lakes and streams. It can also be present in man-made water systems like hot tubs, cooling towers, and plumbing systems. Legionnaires disease is a severe form of pneumonia that can be contracted by inhaling small droplets of water contaminated with the bacteria. Symptoms include high fever, cough, shortness of breath, muscle aches, and headaches. Prompt treatment with antibiotics is necessary to prevent complications and potentially fatal outcomes.Rate this question:

What is true of Listeria monocytogenes? you may choose more than one.
- A.
Rod shaped
- B.
Is gram positive
- C.
Causes listeriosis
- D.
Causes monocytogenosis
Correct Answer(s)
A. Rod shaped
B. Is gram positive
C. Causes listeriosisExplanation
Listeria monocytogenes is a rod-shaped bacterium that is gram-positive. It is known to cause listeriosis, a serious infection that can lead to severe illness or even death, especially in high-risk individuals such as pregnant women, newborns, the elderly, and those with weakened immune systems. However, there is no evidence to suggest that Listeria monocytogenes causes monocytogenosis.Rate this question:

What causes gonorrhea?
Correct Answer(s)
Neisseria gonorrhoeae
neisseria gonorrhoeaeExplanation
The correct answer is Neisseria gonorrhoeae. Neisseria gonorrhoeae is a type of bacteria that causes gonorrhea, a sexually transmitted infection. It is transmitted through sexual contact with an infected person. The bacteria can infect the genitals, rectum, and throat, leading to symptoms such as discharge, pain, and itching. If left untreated, gonorrhea can lead to serious complications, including infertility and increased risk of HIV transmission. Therefore, it is important to seek medical attention and get tested if you suspect you have been exposed to Neisseria gonorrhoeae.Rate this question:

Name one disease that Neisseria meningitidis causes
Correct Answer(s)
meningococcemia
Meningococcemia
meningitis
MeningitisExplanation
Neisseria meningitidis is a bacterium that can cause two main diseases: meningococcemia and meningitis. Meningococcemia is a bloodstream infection caused by the bacteria, while meningitis is an infection that affects the membranes surrounding the brain and spinal cord. Both diseases can be severe and potentially life-threatening if not treated promptly.Rate this question:

What is true of vibrio parahaemolyticus? you may choose more than one
- A.
Causes parahaemolytica
- B.
Is vibrio shaped
- C.
Gram negative
- D.
Causes gastroenteritis
Correct Answer(s)
B. Is vibrio shaped
C. Gram negative
D. Causes gastroenteritisExplanation
Vibrio parahaemolyticus is a bacterium that is vibrio-shaped, meaning it has a curved or comma-like shape. It is also gram-negative, which refers to its cell wall structure. Additionally, Vibrio parahaemolyticus is known to cause gastroenteritis, an inflammation of the stomach and intestines that leads to symptoms such as diarrhea, vomiting, and abdominal pain.Rate this question:

What causes urethritis in males and a UTI in females?
Correct Answer(s)
Ureaplasma urealyticum
ureaplasma urealyticumExplanation
Ureaplasma urealyticum is a type of bacteria that can cause urethritis in males and urinary tract infections (UTIs) in females. Urethritis is inflammation of the urethra, the tube that carries urine from the bladder out of the body, while UTIs are infections that occur in the urinary tract, which includes the bladder, urethra, ureters, and kidneys. Ureaplasma urealyticum can infect the urinary tract, leading to these conditions.Rate this question:
