Serratia is a coliform that

Which of the following pairs is MISMATCHED?

Several cases of non bloody diarrhea with nausea, fever and abdominal pain have occurred among a number of people who ate at the same restaurant. Public health officers find a food sample containing motile noncoliform, Gram-negative bacteria capable of metabolizing glucose. the "food poisoning" resulted from contamination with

Shigellosis can be differentiated from salmonellosis by

What is the causative pathogen for bubonic and pneumonic plague?

Which of the following bacteria requires heme for its growth?

A young woman has a pelvic infection. A specimen contains bacilli that are bile salt tolerant, as shown by black growth on a bile-esculin agar plate. Her infection is likely caused by

Which of the following statements concerning Pasteurella is FALSE?

Cat scratch disease is caused by

Bordetella pertussis causes disease by

Which of the following diseases can be prevented by vaccination?

Legionnairs' disease is diagnosed by

Which of the following statements regarding Coxiella is TRUE?

What is the causative pathogen of Q fever?

How do Prevotella differ from Bacteroides?

Which of the following toxins produced by Bordetella pertussis results in the accumulation of excess mucus in the trachea?

Hemolytic uremic syndrome is caused by

A cystic fibrosis patient develops a severe respiratory infection that resists treatment with standard antibiotics. A specimen from the lungs is greenish in color and contains aerobic motile Gram-negative bacilli. the patient is probably infected with

What is the characteristic lesion of Yersinia pestis?

What is the antimicrobial agent of choice for treating Bacteroides infections?

What metabolic characteristic distinguishes Enterobacteriaceae from Pasteurellaceae?

This growth pattern is characteristic of which organism?

How is pneumonic plague transmitted?

A lesion called _____ is characteristic of infection with Haemophilus ducreyi.

Urinary tract infections with _____ are frequently complicated by the formation of kidney stones.

Infection with ______ usually produces acute upper respiratory disease but may cause meningitis in infants 3-18 months old.

Undiagnosed or untreated infections with Neisseria gonorrhoeae in can progress to

Which of the following is the result of inhalation of aerosols of fresh water containing a bacterial parasite of protozoa?

Which of the following diseases is transmitted by the bite of human body lice?

Inhalation of dried bodily fluids of infected animals may result in

The zoonotic infection _____ in humans is characterized by fluctuating fever and chills, sweating myalgia, and headache.

Which of the following bacteria can metabolize a large range of organic compounds and is a frequent nosocomial pathogen of cystic fibrosis patients?

(there is no abnormal coloration of the mucus in these patients)

Coliforms are distinguished from noncoliforms by their ability to ferment (glucose/ citrate/ lactose).

Neisseria is distinguished from many other Gram-negative pathogens by being (catalase/ oxidase/ dismutase) positive.

Because of the existence of (acute/ symptomatic/ asymptomatic) carriers, the eradication of meningococcal disease is unlikely.

Pseudomonas aeruginoas is an opportunistic pathogen because it is not (anaerobic/ invasive/ virulent).

Unlike other Gram-negative opportunistic bacilli, Bacteroides are (aerotolerant/ faculative/ obligate) anaerobes.

Strains of the same species of enteric bacteria are identified by their (H/ K/ O) antigens, components of the outer membrane.

The pleomorphic bacterium (Coxiella/ Legionella/ Francisella) is an intracellular parasite that can lead to respiratory disease

Pneumonia caused by Klebsiella pneumoniae often involves the destruction of (alveoli/ macrophages/ epithelium) and the production of bloody sputum.

The true pathogen (Salmonella/ Shigella/ Yersinia) is a noncoliform, nonmotile, oxidase-negative member of the Enterobacteriaceae that does not produce hydrogen sulfide.

Scientists have identified over 2000 unique serotypes of Salmonella, but DNA analysis indicates that they belong to a single species: S. (enterica/ typhi/ paratyphi).

Of the three disease caused by Yersinia pestis, only (bubonic/ black/ pneumonic) plague is communicable between humans.

Cat scratch disease is caused by Bartonella (bacillifromis/ henselae/ quintana).

The zoonosis (brucellosis/ bartonellosis/ tularemia) can be acquired by humans in a variety of ways, including insect bites and ingestion of infected animals.

Dermonecrotic toxin is produced during (pertussis/ Legionellosis/ shigellosis) and causes localized constriction and hemorrhage of blood vessels, resulting in cell death and tissue destruction.

People can reduce the chances of contracting rabbit fever by avoiding rabbits, muskrats, and (fleas/ lice/ ticks).
