To write:
- The preliminary identification of the pathogens.
- The delayed diagnosis.
- The reason for the man's infection to reoccur.
Introduction:
Pneumonia is an infection of the lungs with a range of possible causes. It can be severe and life-threatening. It starts with bacterial, viral or fungal infection. The lungs become inflamed and tiny air-sacs, alveoli inside the lungs are filled up with fluid. It is characterized by inflammation of air-spaces in the lungs.

7-year-old boy is brought to the pediatrician with lesions under his lips as shown in the attached
image. Parents report that the lesions developed over the course of a week. On physical examination,
his temperature is 37°C, pulse rate is 80/min, blood pressure is 110/80 mmHg, and respiratory rate is
20/min. A culture of the sample from the lesion yields Gram-positive, catalase-negative, cocci. Which of
the following is the most likely pathogen?
Answers A - E
A Candida albicans
B Coxsackie A virus
C Herpes simplex 1
D Staphylococcus aureus

Q
The patient was an 80-year-old female who 10 days previously had had a cystocele repair performed. At the time of the hospital admission, a urine culture was obtained and revealed >100,000 CFU/ml of an Escherichia coli strain that was susceptible to all antimicrobial agents against which it was tested. Postoperatively, she began a 7-day course of oral cephalexin. She was discharged after an uneventful postoperative course of 3 days. Ten days postoperatively, she presented with a 3-day history of diarrhea. The patient noted multiple watery, loose stools without blood, crampy abdominal pain, and vomiting. She presented with a temperature of 38.2 degrees C, pulse rate of 90/min, respiration rate of 20/min, and blood pressure of 116/53mm Hg. Her white blood cell count was normal, but a large number (53%) of immature polymorphonuclear cells were seen. Physical examination, electrolytes, liver enzymes, and lipase were all within normal limits.

- A 30 year old male patient who was a contractor and building inspector in the Greater Accra region complained of difficulty breathing and was admitted to the Greater Accra Regional hospital with severe respiratory disease. The Physician noted a high fever and cough. Two days before, the patient had inspected an old warehouse, abandoned and infested with rodents. The patient was given intravenous antibiotics, but 2 days into therapy the pneumonia worsened and he developed pulmonary edema. a) Which organism should be suspected of causing this illness?arrow_forwardA 42 year old man developed a “flu-like” syndrome with fever, sore throat, headache, and myalgia. Viral culture was ordered for laboratory confirmation of influenza. Which of the following would be the best specimen for isolating virus responsible for the infection? A- Blood B- Nasopharyngeal washing C- Stool D- Saliva E- Vesicle fluidarrow_forwardPlease refer to the given scenario below. What is the most appropriate sample to be collected to isolate the causative agent of the infection? * A 46-year-old male encountered a motor-vehicular accident (MVA) resulting in multiple injuries on his anterior chest and left lower extremities. Aside from the injury, his medical history was unremarkable. The patient was admitted for nine days and underwent debridement and was discharged with an external fixator. However, during his admission, on his 7m post-operative day, the wound was noted to have persistent purulent, bloody discharge from drain site, which is highly suggestive of surgical site infection (SSI).
