14. One bacterial pathogen can cause symptoms of gastroenteritis in 2 hours after ingestion of contaminated food and another pathogen requires 3 days to cause disease. How do the pathogenic mechanisms of these bacteria differ that explains the difference in incubation time.?
Answer 14: For most of the infectious diseases, the ability to accurately identify the causative pathogen is a critical step in finding the presription treatment. Generally, Bacteria such ascMycobacterium tuberculosisLeginolla pnemophila and Salmonellla species usea slightly different mechanisms of their incubatio period.

Part I – Background on Salmonella Salmonellosis is a gastrointestinal illness caused by bacteria from the genus Salmonella. The illness is characterized by the sudden onset of headache, abdominal pain, diarrhea (which may be bloody), nausea, and sometimes vomiting. Fever is almost always present. The illness typically lasts for 5-7 days and usually does not require treatment unless the patient becomes severely dehydrated or the infection spreads from the intestines. In the immune compromised host or an overwhelming infection in...
Consider that a certain antimicrobial drug prevents bacterial growth. However, when the drug treatment is stopped, the bacteria resumes growth. This antimicrobial drug would be considered. Select one: a. bacteriostatic. b. narrow-spectrum. c. toxic. d. broad-spectrum. e. bacteriocidal. Broad-spectrum drugs target a wide variety of bacterial pathogens. Even when the broad-spectrum drug is capable of killing a target pathogen, it may not be the best treatment. Which statement best explains why a broad spectrum drug might be an undesirable treatment...
Food Microbiology Purpose To utilize the process of fermentation to make yogurt To describe organisms responsible for food borne illnesses and summarize a recent outbreak Introduction Microorganisms have been used for centuries for food preservation and to improve or change its taste. Evidence exists that yogurt, which is milk fermented by bacteria, has been around for over 4000 years. Today, many of the foods we eat are the result of microorganisms acting on foods for a specific and desired effect....
1:14 Back T F Relapse, the recurrence of malaria symptoms after months or even years of no disease, is associated with infections involving either P. vivax or P. ovale. T F If a different patient again experiences paroxysms after a period of time being symptom-free, and is diagnosed to be undergoing recrudescence, they are being exposed to the reactivation of hypnozoites within ytes T F If an individual receives a blood transfusion during a surgery, they could show symptoms of...
