Tiffaney is worried about her newborn son. Ever since she brought Caleb home from the hospital it has been so hard to get him to eat and he seems to be breathing hard all the time. She stopped breastfeeding and tried every formula on the market, but nothing has improved his feeding. So at his one month checkup her stomach is in knots as they place Caleb on the scale. “9 pounds 7oz” says the nurse. Tiffaney realizes Caleb has only gained one pound since he was born and she burst into tears.
In the exam room Dr. Baker checks Caleb for taking extra time feeling and listening to his chest. During the exam Tiffaney explains her struggle with trying to get her son to eat and how he cries almost the entire day. After the exam Dr. Baker says “When I listen to Caleb’s heart I hear an extra sound called a murmur. I want to use an echocardiogram and an ECG to get a good picture of all the parts of his heart.”
After a full day of tests Tiffaney meets with Dr. Baker in his office. “After a careful review of all the information I have discovered that Caleb has a hole in the heart muscle wall between his right and left ventricles. We call it a ventricular septal defect. That is probably why he has been so irritable and hard to feed. The hole is not very big but he will still need to have surgery to repair it” says Dr. Baker. Although the thought of her tiny son having surgery is terrifying Tiffaney is relieved to know why things have been so tough at home.

Case Study

"A 35-year old man is rushed to the hospital with breathlessness, fever, pain and a gross swelling of his left leg. His daughter had contracted chicken pox 3 weeks earlier and he caught the disease from her one-week ago. On visiting his primary care physician, the man was prescribed acyclovir and hydrocortisone cream (the latter to treat the blisters). The male patient was rushed to surgery where he was found to have severe purulence and dead muscle tissue in the calf of his leg, which tracked up to the thigh. Gram positive cocci in chains isolated from the lef were Beta-hemolytic on blood agar"

Please help me answer the following questions..

1. Epidemiology: How does this organism enter the body and how does it spread within the body and go from person to person? How was the disease contracted?

2. Pathogenesis: What are the virulence factors? How does this organsim cause pathology?

3. Laboratory finding: How would you diagnose this organism? What should you find?

PLEASE HELP ME, THANK YOU SO MUCHHH.
