Is Staphylococcus aerobic or anaerobic?

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.

Does Staphylococcus epidermidis need oxygen?

S. epidermidis forms biofilms in low O2 environments. As oxygen concentrations ([O2]) decreased, the metabolism of S. epidermidis was modified ranging from fully aerobic to anaerobic.

Can Staphylococcus epidermidis grow aerobically?

Staphylococcus epidermidis is a well-characterized, nonfastidious, aerobic gram-positive coccus commonly isolated in the clinical microbiology laboratory.

Is Staphylococcus epidermidis a Mesophile?

S. aureus is a mesophilic organism with optimum growth temperature in the range from 37 °C to 40 °C [7-9,17].

Is Staphylococcus aerobic?

Staphylococcus aureus grows best in an aerobic (oxygen-rich) environment but it can also live in anaerobic conditions (without oxygen). The bacterium has a diameter of about 0.8 µm, 60 times smaller than a hair’s breadth. S. aureus is termed an opportunistic pathogen.

Where is Staphylococcus epidermidis found?

Staphylococcus epidermidis lives on everyone’s skin. The bacteria prefer sweaty places, such as your armpits, but are also found on your back and in your nostrils. Together with other micro-organisms, they produce substances from sweat, bringing about the body odour associated with perspiration.

What disease does Staphylococcus epidermidis cause?

Staphylococcus epidermidis can cause wound infections, boils, sinus infections, endocarditis and other inflammations. The bacterium can reside for a long period of time in “hiding places” in the body, where it is not noticed by the immune system, and therefore also not fought.

How does Staphylococcus epidermidis adapt to aerobiosis?

Under aerobiosis, S. epidermidis expressed high oxidoreductase activities, including glycerol-3-phosphate dehydrogenase, pyruvate dehydrogenase, ethanol dehydrogenase and succinate dehydrogenase, as well as cytochromes bo and aa3; while little tendency to form biofilms was observed.

How many species of Staphylococcus epidermidis are there?

Staphylococcus epidermidis is a Gram-positive bacterium, and one of over 40 species belonging to the genus Staphylococcus.

Is the Staphylococcus epidermidis a Gram positive bacteria?

Staphylococcus epidermidis is a Gram-positive bacterium, and one of over 40 species belonging to the genus Staphylococcus. It is part of the normal human flora, typically the skin flora, and less commonly the mucosal flora. It is a facultative anaerobic bacteria.

How are Staphylococcus species different from other anaerobic bacteria?

Staphylococcus species can be differentiated from other aerobic and facultative anaerobic, Gram-positive cocci by several simple tests. Staphylococcus species are facultative anaerobes (capable of growth both aerobically and anaerobically).
