Explanation / Answer

1)

a.beta hemolysis :Beta hemolysis refers to the complete lysis of red blood cells in the media surrounding the bacterial colonies.It is also known as complete hemolysis.The bacteria that cause beta hemolysis are known as beta hemolytic bacteria.

b.antibiotic susceptibility test :This is a test that helps to determine which antibiotics are effective in inhibiting the growth of pathogenic bacteria and to find out drug resistance in pathogenic bacteria.The method by which the test is done is known as Kirby-Baeur method.Other methods are Stokes method,minimum inhibitory concentration methods through agar and broth dilution method.

c.enteric bacteria.The bacteria that reside in the gut and intestine are known as enteric bacteria.They are usually harmless but some are pathogenic as well.They are gram negative and rod shaped.Pathogenic enteric bacteria are E.coli,Salmonella etc.These bacteria mainly cause diarrhoea and dysentry.

d.pyelonephritis :It refers to the mediacl term in which the tissues of the kidney, calyces and the renal pelvis undergo inflammation.The main cause is a bacterial infection that is spread in the urinary tract or reaches the kidney through blood.E.coli and E.faecalis cause pyelonephritis.The symptoms include high fever, vomitting,pain in abdomen and pain while urinating.

e.medical mycology : It is an international journal that is peer -reviewed and focusses mainly on the disease related to fungus that survive in environment, medical or veterinary areas.

2) It can be identified that the sore throat is a strep throat in the following ways:

3) The strategy that should be followed to find the causative agent of bacterial pneumonia are :

4) The code is 37070

5)Clinically relevant spirochetes are :

6)Tuberculosis can be diagnosed as follows:

7) The special requirements that are needed to grow Clostridium in lab is anaerobic conditions.This is because Clostridium are obligate anaerobes and they are killed by normal concentration of oxygen.
