The term "IMViC" is an acronym for each of these tests. "I" is for indole test; "M" is for methyl red test; "V" is for Voges-Proskauer test, and "C" is for citrate test. The lower case "i" is merely for "in" as the Citrate test requires coliform samples to be placed "in Citrate". Triple sugar iron test (TSI), Urease Test and Malonate Test are also included in this test.
For each of the tests, different reagents are added to the species are inoculated and tested.
For Salmonella sp. the IMViC Test result is:
Indole - negative
Methyl red - Positive
Voges-Proskauer - negative
Citrate - positive
C. ferns.
Explanation:
The ferns are ancient plants that have managed to survive until the present. They are not closely related to the dominant plants nowadays, the flowering plants, but instead they are closely related with plants that have gone extinct tens and hundreds of millions years ago. Even though the ferns are not the dominant plants, they have managed to find a niche and firmly hold onto it, so they remained widespread, normally occupying the lower layers of the forests.
Unlike the flowering plants that produce flowers and then seeds in order to reproduce, that is not the case with the ferns. The ferns actually reproduce through spores, being widely dispersed by the wind and managing to spread out and reproduce over relatively large territory very quickly.
Answer:
All of the options are true for a MRSA infection.
Explanation:
<em>Staphylococcus aureus</em> is one of the most frequent pathogens causing hospital and community infections. <em>S. aureus</em> can become very easy methicillin resistant (called MRSA isolates) and others beta-lactam antibiotics (are the ones widely used to treat infections) and usually can be resistant to other class of antibiotics, become a very strong bacteria making treatment options very limited. MRSA isolates can rapidly transfer the methicillin resistance to other species of S<em>taphylococcus</em> and some other bacteria. Also <em>S. aureus</em> can acquire other antibiotic resistant genes making a deadly bacterium for its strong resistance. It is in search how the bacterium acquire this antibiotics resistance ( and other virulence factors genes) and the mechanism involve to develop new drugs to treat MRSA infections with the hope that can´t develop resistance to this new drugs.
<span>The importance of the G0 phase is that during cell division when the cell get a signal that there are enough of cells (not more required) or there is a mutation in the cell that need to be fixed before they differentiate fully or the cell during its division gets damage then it is signalled to rest, and it is this phase that cell leave the cycle and quit dividing. It could be temporary resting period (so when cell again required, or damaged got fixed) then the cells will again join the cycle and continue to divide again or it can also be permanent for example neurons, which are resting in G0 phase and never divides again.</span>
