Step by step
Solved in 2 steps
- Contrast Streptococcal toxic shock syndrome from Staphylococcal toxic shock syndrome.Describe two characteristics of Streptococcus mutans that contribute to its ability to cause dental caries.Identify the causative agent of staphylococcal food poisoning and explain the method for transmission of the bacteria to food sources. Describe the characteristics of the staphylococcal toxin.
- What are the virulence factors of Salmonella typhi? Explain each factors in simple terms.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.Based on disease syndromes and characteristics, and also on their effect on certain cell cultures and serological groupings, five virulence groups of Escherichia coli are recognized. Briefly distinguish between these virulence groups. [Base your answer on virulence factors, pattern of bacterial attachment to host cells, effects of attachment to host cells, production of toxins, and invasiveness] What will the appearance of Escherichia coli be on MacConkey Agar red and Eosin Methylene Blue (EMB) agar, respectively.
- what is the culture media of salmonella typhiDiscuss the events that takes place during meat spoilage by Pseudomonas spp.Using figure (reproduced below) as a guide, explain theprocesses occurring between Salmonella (pink) and the surface of ahost cell (yellow) on both the left and the right side of the photo.
- Briefly explain how urease helps Helicobacter pylori to evade the protective nature of the body.What are some Important facts about staphylococcus capitis? Why are they significant?Write a 1-2 paragraph case study that accurately depicts the disease caused by Clostridium Botulinum. If your organism is transmitted in a specific location or under certain circumstances be sure your patient has been to those locations or engaged in those behaviors that would lead to transmission Have the appropriate timeline in terms of incubation and length of illness. Cover the important symptoms. You do not have to give all possible symptoms, just the typical one. Provide some important laboratory test results without stating the name of your microorganism. Provide the Epidemiology, Pathogenesis, Clinical Manifestations, Laboratory Tests, Treatment and Prevention.
