Correct the answer. Only one answer each question: All of the following are bacteria that causeinfectious gastroenteritis as whole agentEXCEPT:All of the above apply, no exceptionE. coli O157:H7Shigella dysenteriaeCamphylobacter jejuniSalmonella typhimuriumStaphylococcus aureus Which of the following applies to the Zone ofInhibition?None of the answers applyDecreases in size with increased antibioticsolubility or concentrationMeasured as the diameter of growth aroundantibiotic diskIncreases in size with increased antibiotic solubilityor concentrationMeasured as the radius of the area of no growtharound an antibiotic disk

Gastroenteritis is a type of infections that is caused by the microorganisms such as bacteria, viruses and parasites. It takes about 2 weeks to several weeks to completely recover. Antibiotics are used to treat the bacterial infections. 1))The symptoms of gastroenteritis may include diarrhea, vomiting, cramps and abdominal pain. The agents which are responsible for this infections are: A) bacteria B) virus C) parasites. The bacteria like E.coli, salmonella, clostridium, chigella and comphylobacter are responsible for causing such adverse infections. 2) zone of inhibition is defined as the area where the bacterial growth doesnot take place around the antibiotic disc.1) Correct answer Thus from the above explanation, it is clear that the except staphylococcus aureus all bacteria are responsible for causing gastroenteritis. Thus the correct option for the above question will be Option 6) staphylococcus aureus. 2) correct answer Thus from the above explanation , it is clear that the correct answer to be option 5) measured as the area of no growth around the antibiotic disk.Incorrect answer All other options are incorrect because Esherichia coli, shigella dysenterae, camphylobacter jejuni, and salmonella typimurium are responsible for the gastroenteritis disease. Incorrect answer All other options are incorrect because it doesnot denote the exact definition of the zone of inhibition.
