Question 39 Thick polysaccharide capsules are important virulence assets for O Neiserria meningitidis and Streptococcus pneumoniae O Escherichia coli and Vibrio cholera Clostridium tetani and Bacillus anthracis, O Salmonella spp. and Staphylococcus aureus Question 40 2 pts You have two gram-negative organisms (named A and B). A produces 2 exotoxins while B produces no exotoxins. You grow the organisms in liquid medium then boil the cells and medium to create a heat-treated extract. This heated-treated extract is mixed with the mouse food and given to an immune-compromised mouse. The mouse dies within days. The best possible explanation is o Endotoxins from Orism A or Organism cause the lethality The combination of exotoxins and endotoxins caused the lethality Exotoxins from Organism A cause the lethality O Endotoxins from Organism Acause the lethality O Endotoxins from Organism Bcause the lethality Guard\
