What are the Enzymes and Toxins produced by Staphylococcus aureus?

What are the diagnosis for Osteomyelitis

They only grow aerobically (strict aerobes).

True/False: Micrococcus is Microdase positive

Phylum of Staphylococci

It is used to differentiate the pathogenic staph. aureus From non-pathogenic ones

Staphylocci which is Coagulase positive

True/False: Staphylococcus is resistant to 0.04 U of bacitracin.

What is the original colour of VP test?

What are the specimens used in the Laboratory Diagnosis of Staphylococci?

Also known as lemon yellow colonies

True/False: Micrococcus is not susceptible to 0.04 U of bacitracin

It coagulates the fibrinogen in the plasma. Promotes the formation of a fibrin layer around the staphylococci abscess thereby protecting the bacteria from phagocytosis.

It is bound to the cell wall and clots human, rabbit, or pig plasma by directly converting fibrinogen into fibrin.

They are Catalase-producing and facultatively anaerobic except for S. saccharolyticus.

How can bacteria get to the bone?

The exception in staphylococci because it is an obligate anaerobe

What is the positive result for Tube method?

What are the two method that can be used in Coagulase test?

True/False: Staphylococcus is fermentative

It is considered sensitive but definitive method, detects extracellular or free coagulase.

It is the other important of the cell wall aside the peptidoglycan layer.

What are the different types of Hemolysin?

This family is consist of Gram positive cocci, arranged in tetrads, clusters

Where does S. aureus grow?

True/False: Staphylococcus is microdase positive.

Also known as golden yellow colonies

He was the first to see staphylococci in pus specimen in 1878.

Staphylcocci have ___ species and ___ sub species.

It is an extensive exfoliative dermatitis that occurs primarily in newborns and previously healthy children.

It is a very superficial skin infection common in children, usually produces blisters or sores on the face, neck, hands and diaper area. It is characterized by watery bristles, which become pustules and then honey colouted crust.

It breaks down penicillin and other B-lactam drugs. More than 90% of clinical staphylococci isolates are penicillin-resistant as a result of enzyme production.

Staphylococci are gram positive cocci which is classified into these 2 families:

It is the major structural component of the cell wall. It is important in the pathogenesis of staphylococcal infections.

What are the 4 genera of Micrococcaceae?

What does Staphylococcus aureus and S. lugdunensis have in common which makes it possible to confuse it with each other?

Greek word 'Kokkus' means

Type of Coagulase

Who first cultured in liquid media?

Who first observed in pus in 1871?

He named S. aureus and S. albus in 1884

What does CONS stands for?

What is the positive result for Mannitol fermentation test?

True/False: Staphylococcus is not susceptible to antibiotic furazolidone.

It is used to screen catalase positive colonies, detects cell bound coagulase or clumping factor.

It attacks and kills white blood cells, pore forming exotoxin that suppresses phagocytosis and responsible for necrotizing skin and soft tissue infections.

He named the bacteria as "staphylococcus" in 1881

It is an extracellular enzyme that is not bound to the cell wall and causes clot formation when bacterial cells are incubated with plasma.

It is an aggregation of infected furuncles. it may form large abscesses. It is a large are of redness, swelling and pain, punctuated by several sites of drainage pus.

Other slide coagulase Staphylococcus are:

Most commonly used method of Coagulase test

Species of Staphylococcus that are causes of endocarditis

A method of Coagulase test that is not used nowadays

What are the differential tests for Staphylococcus aureus?

Specie of Staphylococcus that is a cause of urinary tract infection

It refers to the inflammation of the bone

It is a folliculitis affecting one or more hair follicles on the edge of the upper or lower eyelid.

It is less toxic than a and B-lysins, produced by all S.aureus strains that cause RBC injury in culture and produces edematous lesions.

It destroys RBC and is associated with the Panton-Valentine leukocidin.

Staphylocci which are Coagulase negative

It causes honeymoon cystitis

What is the pH indicator for Mannitol fermentation test?

A unique property of _________ is its ability to bind to the Fc part of all IgG molecules except IgG3.

It is a chromosomal-mediated toxin and causes almost all cases of menstruation-associated TSS and it stimulates the production of a large amount of cytokines that are responsible for the symptoms.

True/False: Micrococcus is resistant to antibiotic furazolidone.

True/False: Micrococcus utilize sugars oxidatively or not at all in the O/F test.

It enhances invasion and survival in the tissue. Breaks down the hyaluronic acid that is present in the intracellular ground substances of connective tissues, resulting in the spread of bacteria.

Species of Staphylococcus which are causes for nosocomial infection

What is the Family of Staphylococcus?

True/False: Micrococcus is lysed with lysostaphin (sensitive).

It is a serin protease that divides the intracellular bridges of the epidermidis and causes extensive sloughing of the epidermis to produce a burn-like effect on the patient.
