Duke Pathology - Microbiology Cases


Clinical history: Over the course of 1 week, a 6-year-old medical microbiology case studies develops 0. During the next 2 days, some medical microbiology case studies the pustules break, forming shallow erosions covered by a honey-colored crust, medical microbiology case studies. New lesions then form around the crust. The Gram stain from a skin pustule showed gram positive cocci in clusters.

The organism grew on sheep blood agar SBA and medical microbiology case studies catalase positive. What is the most likely microorganism? Staphylococcus aureus B. Staphylococcus epidermidis C. Streptococcus pyogenes D. Streptococcus pneumonia. Clinical History: This year-old male's illness began 10 weeks prior to death, with an episode of "flu". Two weeks later his urine became "smoky". He died from a pulmonary embolus.

The kidney excretes soluble waste from the body and controls electrolyte balance. It consists of the medical microbiology case studies and the medulla. Within the outer cortex, glomeruli with delicate capillary loops are seen. The basement membrane is thin and without inflammation or thickening, medical microbiology case studies.

The interstitium demonstrates no evidence of inflammation or fibrosis. In the areas between the glomeruli, tubules and arterioles are seen. The tubules are intact. The vessels exhibit no narrowing or wall thickening. The inner medulla of the kidney contains only tubules and blood vessels.

Larger arteries and veins are located at the interface between cortex and medulla. The throat culture obtained exhibited gram positive cocci in chains.

It also showed beta-hemolysis on sheep blood agar SBA and was catalase negative. What was the most likely organism? An elderly wheelchair bound man had a history of recurrent urinary tract infections.

He presents with new onset of fever, chills, and confusion, medical microbiology case studies. Blood cultures were drawn. The organism grown was non-hemolytic, catalase negative, and PYR positive. Gram stain showed gram positive cocci.

What is the most likely organism? Clinical History: A year-old male became ill approximately 2 to 3 weeks ago following an alcoholic spree.

He had nausea, vomiting, dehydration, confusion and high fever. He died suddenly shortly after admission. Community acquired atypical pneumonia can be caused by which of the following organisms? Clinical History: A year-old male had rheumatic heart disease for thirty years.

Three months prior to death he began to have episodes of fever and chills accompanied by signs of worsening congestive heart failure. Splinter hemorrhages and purpuric skin rashes were noted three weeks before death. Which of these organisms are normal flora of the throat and are associated with dental caries, brain abscesses, and endocarditis? A patient with suspected infectious endocarditis has a St.

Blood culture shows non-hemolytic, small, white colonies. The organism was Gram positive, catalase positive and coagulase negative. A throat culture grows normal oropharyngeal flora. What alpha-hemolytic organism is most likely to be isolated on the blood agar? Staphylococcus epidermidis B. Staphylococcus viridans C, medical microbiology case studies.

Streptococcus pneumoniae D. Peptostreptococcus species. The coagulase test for the organism is positive. What is the genus and species of the organism? Streptococcus agalactiae C. Staphylococcus epidermidis.

Clinical history: A year-old female dairy farmer develops a severe headache and neck stiffness. On physical examination, medical microbiology case studies, her temperature is She has no papilledema.

A lumbar puncture is performed, and a Gram stain of the CSF obtained shows many short, gram-positive rods. Based on the clinical findings presented, what is the most likely causative agent in the case above? A sputum gram stain of an elderly person with cough and fever shows gram positive cocci in pairs. A month-old child of a family from Mexico living in Durham was noted by his mother to have a grand mal seizure with shaking of arms and legs by medical microbiology case studies description given to the EMT.

The EMTs found the child limp and unresponsive. Blood cultures and lumbar puncture were performed. CSF findings were as follows:.

Gram stain showed PMNs and occasional Gram-negative coccobacillary organisms. What is the most likely organism in this case? Clinical History: A 25 year-old woman had pelvic pain, fever, and vaginal discharge for 3 weeks.

On physical examination, she has lower abdominal adnexal tenderness and a painful, swollen left knee. The fallopian tube is lined by ciliated columnar epithelium that aid in transport of the ovum to the uterus. The epithelium is arranged in fronds that project medical microbiology case studies the lumen. The wall consists of smooth muscle and connective tissue. A year-old male presents with urethritis. The Gram stain shows intracellular gram positive cocci. Clinical History: A year-old male had a " neurogenic bladder ", caused by a spinal cord tumor.

He had multiple bladder infections which were treated with antibiotics. He had surgery to remove the tumor. Postoperatively, he developed fever and costovertebral angle tenderness which did not respond to antibiotics. He expired and an autopsy was performed. The gram stain also showed gram negative rods.

Clinical History: year-old African American female had been hemiplegic on the right side for 3 months prior to death. She developed malaise, fever and chills after visiting with her grandchildren. Her infection progressed. She developed dyspnea and expired.

Based on these clinical findings, what is the best diagnosis and likely causative agent? What is the most likely cause medical microbiology case studies this disease in most adults? What organism would be most likely to cause a persistent infection in cystic fibrosis? Clinical history: A year-old homeless, alcoholic man had a fever and a cough productive of thick sputum that worsened over several days. His temperature is Diffuse crackles are heard at the right lung base.

Laboratory studies are as follows:. Based on these clinical findings, what is the likely causative agent? An year-old Duke freshman presented to student health with severe headache, fever, and disorientation. A lumbar tap was performed with the following results:. The gram stain of the spinal fluid revealed numerous PMNs with intracellular gram-negative diplococci.

Clinical history: A year-old man incurs extensive thermal burns to his skin and undergoes skin grafting procedures in the surgical intensive care unit, medical microbiology case studies. Two weeks later, he has increasing respiratory distress, medical microbiology case studies. Laboratory studies show hemoglobin of A chest radiograph shows extensive bilateral infiltrates with patchy areas of consolidation.

Image Gallery:. The organism was oxidase positive.
