Klebsiella

True or false: Staphylococcus aureus is a gram-negative bacterium.

True or false: Staphylococcus aureus is the most virulent species of Staphylococcus.

True or false: Staphylococcus aureus is part of the normal flora of the skin and mucus membranes.

True or false: Staphylococcus aureus infections are typically characterized by pustules surrounded by necrotic tissue.

True or false: Staphylococcus aureus enterotoxins are heat-stable and can cause diarrhea and vomiting.

True or false: Scalded Skin Syndrome is most common in adults over 50 years old.

True or false: Streptococcus pyogenes is also known as Group A Strep.

True or false: Streptococcus pyogenes is a gram-negative bacterium.

True or false: Streptococcus pyogenes can cause pneumonia, meningitis, or bacteremia.

True or false: Erysipelas is a form of cellulitis caused by Streptococcus pyogenes.

True or false: Rheumatic fever is a suppurative sequelae of Streptococcus pyogenes infection.

True or false: Streptococcus pneumoniae is a gram-positive bacterium.

True or false: Neisseria gonorrhoeae can cause infections in the urethra, endocervix, anorectal, and pharynx.

True or false: Neisseria meningitidis is a major cause of bacterial meningitis in young adults.

Klebsiella is generally associated with gram-positive bacteria.

Salmonella is divided into over 1700 subspecies and serotypes.

Salmonella infection can be spread through contaminated food and water.

Salmonella enterocolitis is a severe form of Salmonella disease.

Shigella is a highly contagious intestinal pathogen.

Escherichia coli is a normal flora of the gastrointestinal tract.

Escherichia coli enterohemorrhagic strain produces a toxin identical to Shigella.

Klebsiella is a normal inhabitant of the upper respiratory tract in approximately 5% of the population.

Proteus spp. is a normal intestinal flora and an opportunistic pathogen.

Yersinia pestis is transmitted through rat flea bites and airborne droplets.

P. mirabilis and P. vulgaris are the most common isolates of Proteus.

Vibrio cholerae is a curved gram-negative rod typically found in water and is part of the normal flora.

Cholera is caused by toxigenic strains O1 and O139 of Vibrio cholerae.

Cholera is mainly spread through contaminated water or improperly prepared food.

Non-01 and O139 strains of Vibrio cholerae do not produce toxins and cause a milder form of gastroenteritis.

Cholera toxin (choleragen) causes mucosal cells to hypo secrete water and electrolytes, leading to severe dehydration and death.
