- Which 2 bacteria in the list below matches with the unknown 1 and 2 tests attached !! For example ,unknown 1 is E.Coli. Enterococcus faecalis Pseudomonas aeruginosa Bacillus subtilus Staphylococcus aureus Escherichia coli Staphylococcus epidermidis Streptococcus pyogenes Streptococcus pneumoniaeWhich of the following is NOT true about poliomyelitis? Poliovirus is sometimes spread to the central nervous system by viremia Initial poliovirus replication occurs in the throat and small intestine The Salk inactivated (killed whole agent) polio vaccine prevents paralytic polio but not community transmission of wild polioviruses None of the other four answers (All are true about poliomyelitis) Paralysis occurs in a large majority of persons who are infected with poliovirusAnswer all of the following true or false questions: True / False: Choose the answer that best fits each statement. The presence of Escherichia coli in water is used as an indication of fecal contamination. The Vibrio species are characterized as being curved, gram negative bacteria with polar flagella. Chlamydia, Rickettsia and Mycoplasma are all obligate intracellular parasites. Neisseria, Staphylococcus, and Streptococcus are all gram-positive cocci. Tetanus, botulism, and diphtheria are diseases caused by gram positive, soil-dwelling, spore- forming rods. Most togaviruses are transmitted to humans via insect bites. The reason why dogs do not get measles is because their cells lack the correct receptor sites for that virus. Glycoprotein spikes are found on the capsids of viruses. A naked virus lacks a capsid. The polioviruses and hepatitis A virus are transmitted by contaminated food or water. Staphylococcus grows best in a high salt environment.…
