Why do you think Griffith called the mystery material the transforming principle?
The material whatever it was, it contained information that changed the harmless bacteria into disease causing bacteria.
What result from Griffith experiment suggested that the cause of pneumonia was not a chemical poison released by the diseases causing bacteria?
The difference between "walking pneumonia" and "true pneumonia".
What blood cells engulfing eating disease causing bacteria is an example of what?
White blood cells engulfing and destroying disease-causing bacteria is an example of immunity.
What does it mean to be pathogenic organism?
The word pathogen means to be disease causing.
What bacteria is usually the cause of mastitis?
The most common bacteria causing mastitis is called Staphylococcus aureus.
What happened when Griffith injected mice with a mixture of heat-killed pneumonia-causing bacteria and live bacteria of the harmless type?
that it was very gay
Explain how the bacteria in griffith's experiment were transformed?
The harmless living bacteria took in pneumonia-causing DNA(genes) from the heat-killed, pneumonia-causing bacteria, as a result of which the harmless bacteria changed into bacteria that cause pneumonia.

What results from Griffiths experiment suggested that the cause of pneumonia was not a chemical poison by the disease-causing bacteria?
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice.

Who Concluded that bacteria could be transformed from harmless to disease by an unknown factor?
In 1927, Fredric Griffith concluded that bacteria could be transformed from harmless to disease-causing by introducing a factor that was not yet identified. This changing factor was eventually discovered to be DNA, the basis for all biological reproduction.
What result from Griffiths experiment suggested that the cause of pneumonia wasnt a chemical poison?
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice. The Mice survived, suggesting that the cause of pneumonia was not a chemical poison released by the disease-causing bacteria.
The strain of bacteria that caused pneumonia grew into what colonies on culture plates?
The disease-causing strain of bacteria grew into smooth colonies on culture plates, whereas the harmless strain produced with rough edges.
What is pneumococcal polysaccharide vaccine?
Pneumococcal polysaccharide disease is caused by a bacteria. It can be deadly but a vaccine was developed to head off the disease before it starts. The vaccine works when a small amount of the bacteria is injected into the patient and his or her immunity works against the disease, causing immunity.
What traps disease causing bacteria?
Mucus in the respiratory tract traps disease-causing bacteria.
What did griffin observe when he injected into mice a mixture of heat killed disease causing bacteria and live harmless bacteria?
The mice died. This was a fundamental experiment in the history of genetics and helped to establish that DNA was the information and gene carrier for all life. To understand it a little better it's important to know that the heat killed (virulent) bacteria killed the mice when it was living. And the non-virulent did not. But when combined, the non-virulent absorbed some of the DNA from the virulent and was able to make a protective coat that shielded it from the animals immune system... allowing it to kill the mice.
