A patient in ICU with an indwelling medical device is presenting with invasive infection
symptoms, specifically fever and chills. They have been on a course of antibiotics that
has not alleviated the condition.
a) What type of organism do you suspect is causing the infection and why?
About becterial enzymes, it is CORRECT to affirm that:
a). Some becterial enzymes can help the microbe fight the immune system, by destroying lgA.b). Coagulases are enzymes that use the host's fibrinogen and form a semi-solid get that isolates amd protects the bacteria.c). Some bacterial enzymes such as hyaluronidase can help the microble move through the host's tissus by destroying the tissue's components.d). Fibrolysin is an enzymes that can help from blood clots.
At autopsy, the most prominent findings were bronchopneumonia with focal organization and hemorrhage in the right lung. Stains of the lung tissue were negative by Gram, methenamine silver, and acid-fast methods, but Dieterle silver stains revealed short bacilli. Lung cultures yielded Gram-negative bacilli, which grew aerobically on buffered charcoal-yeast extract, but not on blood or chocolate agar. The organisms resembled Legionella, but failed to stain with immunofluorescence conjugates for Legionella pneumophila and multiple other species (L minded, L longbeachae, L gormanii, L dumoffi, L bozemanii). The organism was sent to the Centers for Disease Control and Prevention, where it was eventually identified as a new species of Legionella. What is the most probable source of this man's infection?

- Give a disease-causing pathogen or microbe and answer the following questions. 1. What is the name of the pathogen causing the disease? 2. What disease does the pathogen cause? 3. How is disease transmitted? 4. What are the symptoms of the disease? 5. How long does it last for? 6. Can the disease be treated? 7. Is there a vaccine for the disease?arrow_forwardIf a patient suspected to have sepsis or meningitis, samples for bacterial testing should be taken before giving antibiotics. Explain why?arrow_forwardTwo patients, with identical medical histories are in adjacent hospital beds. Each is infected with Streptococcus pneumoniae. Patient A's infection progresses to pneumonia while Patient B's infection resolves quickly. The microbial stain of the lung fluid from Patient A indicated the bacterial cells had a capsule, while Patient B's lung fluid stain did not. Why did the capsule affect the course of the infection in Patient A?arrow_forward
- Choose the false statement below. O Having Helicobacter pylori as part of the normal body flora decreases the likelihood that a person will develop esophageal cancer. O The normal skin flora of a newborn baby delivered by Caesarian section is the same as that of a baby born via vaginal birth. Babies born via vaginal birth are coated in a protective acidic film created by microbial fermentation in the mother's vaginal canal. Question 19 Choose the false statement below. O A reservoir differs from a fomite as the reservoir is a place of microbial growth. O An asymptomatic host of a microbe may be considered a reservoir if there is no disease state present. O Carriers of a disease show no symptoms nor do they shed microbes passing the disease to someone else.arrow_forwardA culture of Staphylococcus is diluted as follows:(1) 20mL are added to 80mL of water.(2) 10uL from (1) are then added to 9.99mL of water.(3) A 10-2 dilution is made from tube # (2).(4) 100uL from (3) are plated for a pour plate and incubated. There were 34 colonies counted on one quarter of the plate following incubation. a) What was the overall dilution?b) How many cfu/mL were present in the original culture?arrow_forwardThe patient was a 44 year-old male with a past medical history significant for hypertension, non-insulin-dependent diabetes, high cholesterol, and heavy smoking (2 packs/day). He presented to the emergency room with complaints of chest pain and was found to have suffered a myocardial infarction (heart attack). A cardiac catheterization on hospital day 3 showed three arterial occlusions, and he underwent a triple-bypass on hospital day 5. On day 7, he developed septic shock with acute respiratory and renal failure, requiring intubation. He had a fever at that time of 39.3° C and two blood cultures were obtained. A chest x-ray showed left lung pleural effusion and a chest tube was inserted to drain the effusion. On day 11, pus was leaking from the sternal wound. Cultures derived from the wound and from the chest tube grew the organism noted in figures 1 and 2. A Kirby-Bauer disk diffusion assay is shown in figure 3.

- Why is aseptic urine collection important when cultures are ordered? If you counted 20 colonies from a 0.01-ml inoculum of a 1:10 dilution of urine, how many organisms per milliliter of specimen would you report? Is this number significant? What can you learn from visual inspection of a urine specimen? How would you relate these to the microorganisms present in the sample? How are UTIs acquired/transmitted? Explain why E. coli is frequently implicated in cystitis in females.arrow_forwardA 65-year-old woman has a long-term central venous catheter for intravenous therapy. She develops fever and subsequently has multiple blood cultures positive for Staphylococcus epidermidis. All of the S. epidermidis isolates have the same colony morphology and antimicrobial susceptibility pattern, suggesting that they are the same strain. In what possible way do you think she has contracted the bacteria? Which link in the chain of infection has broken in this particular scenario and what will be your advice to avoid such infections?arrow_forwardA farmer working on a piece of machinery gets his shirtsleeve caught in a moving piece of the equipment. His shirt is sliced, and a sharp blade covered in mud slices through his upper arm. He attempts to control the bleeding and immediately seeks medical attention. After 3 days, he develops a fever and his arm becomes extremely swollen and painful. Pulling back the bandages, he finds that the wound has become blackened and is leaking bloody fluid. Microscopic analysis of the fluid reveals the presence of gram-positive bacilli. a. Discuss what condition the patient is suffering from and the likely causative agent of this infection. b. Explain how the patient contracted this pathogenic microbe and what virulence factors contributed to the pathogenesis seen at the wound site. c. In addition to antibiotics, the physician prescribes hyperbaric therapy. Describe what this treatment involves and how it could be therapeutic to this patient.arrow_forward
