Why is a coagulase positive organism considered to be more virulent than a strain that does not produce coagulase?
A coagulase-positive organism, such as Staphylococcus aureus, is considered more virulent because coagulase facilitates the formation of fibrin clots around the bacteria, helping to protect them from the host's immune system. This ability to form clots can also enhance the organism's capacity to establish localized infections. In contrast, coagulase-negative strains lack this mechanism, making them generally less effective at evading immune responses and establishing infections. Thus, the presence of coagulase is a key factor in the virulence of certain pathogens.

What is a coagulase test used for?
The coagulase test is used to differentiate between Staphylococcus aureus (coagulase positive) and other Staphylococcus species (coagulase negative). Staphylococcus aureus is a pathogenic bacterium, while other species are often less virulent. The test involves detecting the ability of the bacterium to coagulate plasma by producing the enzyme coagulase.
What is the antonym of virulent?
The antonyms of virulent: gentle; kind; nice; harmless; healthy; nonpoisonous
A virus that kills its host is said to be?
A virus that kills its host is said to be virulent. Virulent viruses can cause serious illness or death in their host organisms.
What was the molecule that caused transformation in Griffith's pneumonia experiment?
The molecule that caused transformation in Griffith's pneumonia experiment was DNA. Specifically, it was the transfer of DNA from heat-killed virulent bacteria to live non-virulent bacteria that resulted in the transformation of the non-virulent bacteria into a virulent form.
Why was the mixture of S bacteria and R BACTERIA virulent?
The live R bacteria acquired a capsule and became live, virulent S bacteria.

What is a weak strain in microbiology?
An organism that isn't very virulent.
What is the principle behind the coagulase test?
in the coagulase test, normally a virulent staphylococcus is put into plasma. plasma contains the plasma protein fibrinogen. when fibrinogen is acted upon by a fibrinogenase, it is then converted to fibrin. fibrin has te ability to form clots. so in the case of staphylococcus aureus which has the enzyme coagulase also called fibrinogenase, the enzyme acts on the fibrinogen in plasma which is converted to fibrin hence the clots that are seen suspending in the solution after 4 hours.
What is the name of the small organism that may cause disease or rotting?
Pathogens causes diseases . the more virulent the more dangerous.
What is a virulent phages?
phages of virulent.
What is the antonym of virulent?
The antonyms of virulent: gentle; kind; nice; harmless; healthy; nonpoisonous
Why is the term appropriate given to Griffiths observations is transformation?
The term "transformation" is appropriate for Griffiths' observations because it describes the process by which genetic material from one organism can change the characteristics of another organism. In his classic experiments with Streptococcus pneumoniae, Griffith demonstrated that non-virulent bacteria could become virulent when exposed to heat-killed virulent strains, indicating a transfer of genetic information. This process of acquiring new traits through the uptake of foreign DNA is fundamentally what transformation entails in a biological context.
What does anti virulent mean?
Virulent means very posinous or dangerous.
Can you use Virulent in a sentence?
he came down with a virulent type of disease
A sharp criticism can be made with an remark?
virulent
How would use virulent be used in a sentence?
this bacteria is virulent strain
Can you give a sentence for the word virulent?
