What kills Micrococcus luteus?

Lysozyme. Lysozyme was described by Fleming, who noted both its wide distribution and its remarkable ability to lyse certain gram-positive bacteria, such as Micrococcus lysodeikticus. Lysozyme is a very cationic protein of approximately 14.4 kDa.

What type of organism is Micrococcus luteus?

Micrococcus luteus (M. luteus) is a Gram-positive to Gram-variable, non-motile, coccus, saprotrophic bacterium. It can form in tetrads or irregular clusters but not in chains and belongs to the family Micrococcaceae.

Does lysozyme inhibit the growth of Micrococcus luteus?

Lysozyme performed suitable functioning on the Micrococcus luteus but there was no affect on E. ... In Gram negative bacteria, the murein layer was limited, therefore, the attack of lysozyme was too limited. ...

Does Micrococcus luteus have virulence factors?

When compared against the virulence factor database [23], the genome of Micrococcus luteus strain O'Kane showed 527 virulence factor hits (23% of the protein-coding genes). These included secretion systems (type I), and antibiotic resistance genes among others.

Is Pseudomonas fluorescens an obligate Aerobe?

As its name implies, it secretes a soluble greenish fluorescent pigment called fluorescein, particularly under conditions of low iron availability. It is an obligate aerobe, except for some strains that can utilize NO₃ as an electron acceptor in place of O₂.

Is M Luteus a coliform?

General characterization of bacteria is made with respect to their most common impact on human health. Micrococcus luteus is a Gram-positive spherical, saprotrophic bacterium, and is an obligate aerobe. ... Coliform bacteria are a commonly used as a bacterial indicator of sanitation.

What is the difference between Micrococcus and Staphylococcus?

The main difference between Micrococcus and Staphylococcus is that Micrococcus rarely causes infections whereas Staphylococcus often involves in clinical infections. ... Micrococcus and Staphylococcus are Gram-positive cocci that are non-motile, non-sporing, and Catalase positive.

Is Staphylococcus aerobic or anaerobic?

Staphylococcus aureus is a gram-positive facultative aerobe that can grow in the absence of oxygen by fermentation or by using an alternative electron acceptor.

Is S epidermidis motile?

Staphylococcus epidermidis is a very hardy microorganism, consisting of nonmotile, Gram-positive cocci, arranged in grape-like clusters.

Why is Micrococcus luteus yellow?

It is a high G + C ratio bacterium. Micrococcus luteus is coagulase negative, bacitracin susceptible, and forms bright yellow colonies on nutrient agar.

What disease does Micrococcus luteus cause?

Pathogenicity: Although generally a harmless saprophyte, Micrococcus luteus can act as an opportunistic pathogen. It has been associated with a variety of illnesses including meningitis, septic arthritis, endocarditis, chronic cutaneous infections in HIV positive patients, and catheter infections.

Would Micrococcus luteus be sensitive to lysozyme?

1 He also discovered and named a yellow bacterium, Micrococcus lysodeikticus (now M luteus), that was highly susceptible to lysozyme-mediated killing.

Is staph Gram positive cocci?

Gram-positive cocci: Staphylococcus aureus is a gram-positive, catalase-positive, coagulase-positive cocci in clusters. S. aureus can cause inflammatory diseases, including skin infections, pneumonia, endocarditis, septic arthritis, osteomyelitis, and abscesses.

Is micrococcus aerobic or anaerobic?

Characteristics. Micrococcus are aerobic, Gram-positive cocci ranging in size from 0.5 to 2.0 μm in diameter. They occur in pairs, tetrads or clusters but not in chains.

Is M Luteus pathogenic?

Micrococcus luteus is considered a non-pathogenic saprophyte of human skin and eye. Disease in man caused by this organism is not recorded in medical literature. We present a case of septic shock cause by M luteus.
