Which description below respresents Rickettsia and Ehrlichia?
-
Produce capsules, mucoid colonies, are distinguished from Klebsiella sps. by various culture/biochemical tests. Cause nosocomial/opportunistic urinary and respiratory infections.
-
Opportunistic pathogen, produces red colony pigments, frequently associated with nosocomial infections. May cause urinary and serious respiratory infections in weakened hosts. May colonize catheters, saline solutions, and other similar objects. Not sensitive to ampicillin.
-
Produces meningitis, otitis, bronchitis, pneumonias. Requires hemolyzed blood in culture medium for growth. Rifampin sensitive. Vaccine available (Hib).
-
Primarily arthropod borne (fleas, lice & ticks), multiply in bloodstream and cause high fevers, rashes, and collapse. Obligate intracellular parasites, non-motile, pleomorphic bacteria.
Correct Answer
A. Primarily arthropod borne (fleas, lice & ticks), multiply in bloodstream and cause high fevers, rashes, and collapse. Obligate intracellular parasites, non-motile, pleomorphic bacteria.Explanation
The correct answer describes Rickettsia and Ehrlichia as primarily arthropod borne, multiplying in the bloodstream and causing high fevers, rashes, and collapse. It also states that they are obligate intracellular parasites, non-motile, and pleomorphic bacteria. This description accurately represents the characteristics and behavior of Rickettsia and Ehrlichia.Rate this question:

The pathogen that causes the flea-borne bubonic plague is:
-
Yersinia Pestis
-
Rickettsia Typhi
-
Shigella Flexneri
-
Vibrionaceae Vulnificans
Correct Answer
A. Yersinia PestisExplanation
Yersinia Pestis is the correct answer because it is the specific pathogen that causes the flea-borne bubonic plague. This bacterium is primarily transmitted through fleas that infest rats and other small mammals. Once infected, humans can develop symptoms such as fever, chills, swollen lymph nodes, and potentially fatal complications if left untreated. Rickettsia Typhi, Shigella Flexneri, and Vibrionaceae Vulnificans are not associated with the bubonic plague, making them incorrect choices.Rate this question:

Bacterioides are:
-
Species responsible for serious infections following surgery, puncture wounds, and animal & human bites. Anaerobic organisms found in intestines and mouths of humans and animals.
-
Food intoxications acquired by eating raw or undercooked shellfish.
-
Primarily arthropod borne (fleas, lice & ticks), multiply in bloodstream and cause high fevers, rashes, and collapse.
-
Opportunistic pathogen causing a fatal pneumonia in immunocompromised individuals. Sensitive to tetracyclines.
Correct Answer
A. Species responsible for serious infections following surgery, puncture wounds, and animal & human bites. Anaerobic organisms found in intestines and mouths of humans and animals.Explanation
Bacterioides are anaerobic organisms that are commonly found in the intestines and mouths of both humans and animals. They are responsible for causing serious infections that can occur after surgeries, puncture wounds, and bites from animals or humans. These infections can be severe and require medical intervention. Bacterioides are known to be opportunistic pathogens, meaning they can cause disease in individuals with weakened immune systems. They are also sensitive to tetracyclines, a type of antibiotic.Rate this question:

Pasteurella are rod-shaped and normally infect:
-
Pigs.
-
Goats.
-
Wine and cheeses.
-
Cattles, fowls, dogs and cats.
Correct Answer
A. Cattles, fowls, dogs and cats.Explanation
Pasteurella is a type of bacteria that is commonly found in the respiratory tracts of various animals, including cattle, fowls, dogs, and cats. It can cause infections in these animals, particularly respiratory infections. Therefore, the correct answer is cattles, fowls, dogs, and cats.Rate this question:

Shigella is sensitive to Ampicillin/Chloramphenicol/Trimethoprim, the same as ____________.
Correct Answer
SalmonellaExplanation
Shigella and Salmonella are both types of bacteria that can cause gastrointestinal infections. In this context, being "sensitive" means that these bacteria can be effectively treated with Ampicillin, Chloramphenicol, and Trimethoprim antibiotics. Therefore, the correct answer is Salmonella because it shares the same susceptibility to these antibiotics as Shigella.Rate this question:

Gastroenteritis caused by uncooked shellfish and cholera are caused by bacteria from the genus:(Note: They are also monotrichous)
-
Salmonella
-
Pasteurellaceae
-
Vibrionaceae
-
Gardnerella
Correct Answer
A. VibrionaceaeExplanation
Gastroenteritis caused by uncooked shellfish and cholera are both caused by bacteria from the genus Vibrionaceae. Vibrionaceae is a family of bacteria that are known for their monotrichous flagella, meaning they have a single flagellum for movement. Salmonella, Pasteurellaceae, and Gardnerella are not known to cause gastroenteritis or cholera, making Vibrionaceae the correct answer.Rate this question:

The leading cause of non‑gonococcal urethritis in humans (sexually transmitted) is:
-
Treponema pallidum
-
The genus Neisseria
-
Garnerella vaginalis
-
Chlamydia trachomatis
Correct Answer
A. Chlamydia trachomatisExplanation
Chlamydia trachomatis is the leading cause of non-gonococcal urethritis in humans. This sexually transmitted infection commonly affects the urethra, causing inflammation and discomfort. Chlamydia trachomatis is a bacterium that can be transmitted through sexual contact with an infected individual. It is important to diagnose and treat this infection promptly to prevent complications and further transmission.Rate this question:

Rocky Mountain Spotted Fever is caused by:
-
R. Rickettsii
-
R. Prowazekii
Correct Answer
A. R. RickettsiiExplanation
Rocky Mountain Spotted Fever is caused by R. Rickettsii. This bacterium is transmitted to humans through the bite of infected ticks. It is named after the Rocky Mountain region where it was first identified. R. Rickettsii infects the lining of blood vessels, leading to symptoms such as high fever, headache, rash, and muscle aches. If left untreated, it can cause severe complications and even death. Therefore, it is important to recognize the symptoms and seek prompt medical attention for appropriate treatment.Rate this question:
