Question
Chapter 54, Problem 2CA
Summary Introduction
To explain:
Whether the sprouts are not the source of the enteropathogenic E.coli after the identification of low levels of these bacteria by HPC.
Introduction:
The heterotrophic plate count or HPC is also known as the standard plate count. It is a method for the estimation of the number of culturable and live heterotrophic bacteria in water. Also in measuring the variations in swimming pools or during the treatment and distribution of water.

O Lipase which digests lipids and B-lactamase which breaks the matrix between cells. O coagulase which dissolves blood clots and staphlokinase which clots the blood. coagulase which clots the blood and B-lactamase which conveys resistance to penicillin.

His main job activity was spreading bark mulch in garden beds. Last August he rapidly developed severe shortness of breath, a persistent cough, and chest pains. On admittance to the hospital, radiological examination revealed large “cotton ball” densities in both of his lungs. Culture of his lung aspirate grew Aspergillus fumigatus. TJ was given IV amphotericin B and assisted mechanical ventilation via a tracheotomy. He slowly improved in the hospital, but also contracted 2 other respiratory infections with Pseudomonas aeruginosa and Strep. faecalis. These infections were treated with appropriate antibiotics.TJ had 4 sisters and 2 brothers. One of his brothers had a perirectal abscess in infancy but otherwise has been well.TJ’s white blood cell count was in the normal range, with ~65% neutrophils, 30% lymphocytes, and ~5% monocytes.

- Two microbiologists are writing a textbook, but they cannot agree where to place the discussion of botulism. One favored the chapter on nervous system infections, whereas the other insisted on the chapter covering digestive system infections. Where do you think the discussion should be placed, and why?arrow_forwardCoagulase is aknown factor in the ability of S. aureus to cause infection. However, coagulases-negative staphylococci may be pathogenic as well. What are some of the factors that contribute to virulence of coagulase-negative bacteria?arrow_forwardMatch the description listed below to the correct bacterium. Grows in intestine of ruminants like cows. [Choose ] Can be found in raw milk. If ingested, can cause spontaneous miscarriage in women, neonatal sepsis and meningitis [Choose ] Listeria monocytogenes_ Can grow in high salt environments. Makes a Staphylococcus aureus_ heat stable enterotoxin Campylobacter_ When the toxin this pathogen makes is _Vibrio cholerae_ ingested, can cause "projectile vomiting" Streptococcus pyogenes_ Can grow as a mesophile in humans, but also can grow as a psychrophile in refrigerators [ Choose ] A leading cause of food-borne infections, grows on fecal contaminated raw poultry (e.g. raw chicken), forming a biofilm.

- All of the following pertain to listeriosis, except 1) intrauterine infection usually results in fetal death. 2) enterotoxin of the organism causes symptoms. 3) it causes a serious septicemia and meningitis in the elderly, immunocompromised, and infants. U 4) it causes symptoms of fever, diarrhea, and sore throat. 5) adequate pasteurization and thorough cooking of food can improve prevention.arrow_forwardOnce these pathogens enter the host the difference in environmental conditions signals for them to germinate and turn into growing cells. Compare Inhalation anthrax (Bacillus anthracis) to Tetanus (Clostridium tetani). Besides endospores used in transmission, what is a simple explanation to help explain how each microbe survives and grows in each location?arrow_forwardI know that Enterobacter Clocoae was supposed to test positive for the catalase test.
