Using the information below to answer the following three questions. A pathogenic extracellular bacterial species is transmitted through aerosols and causes respiratory infections. The pathogen does not produce a toxin but does cause damage during infection. Question 10 3.5pts What can we assume about the pathogen? Select all that apply. the pathogen produces an adhesin that binds to celis in the respiratory tract the pathogen requires nutrients from its host the pathogen produces an invasin the pathogen has some mechanisms to evade the immune system the pathogen is not cleared by the mucociliery cscalatorThe pathogen secretes enzymes into the lungs and causes damage. What is the most likely function of these enzymes and how are they secreted? to kill competing sibling bacteria; secretion system to damage cells and release nutrients; horizontal gene transfer to kill competing sibling bacteria; horizontal gene transfer to damage cells and release nutrients; secretion system Question 12 2.5pts Humans are considered a dead-end host for these bacteria, meaning there is no person-to-person: transmission. True or false: the bacteria do not meet the requirements to be considered a pathogen. True false.

1. Using the information below to answer the following three questions. A pathogenic extracellular
bacterial species is transmitted through aerosols and causes respiratory infections. The pathogen
does not produce a toxin but does cause damage during infection. Question 10 3.5pts What can
we assume about the pathogen? Select all that apply. the pathogen produces an adhesin that
binds to celis in the respiratory tract the pathogen requires nutrients from its host the pathogen
produces an invasin the pathogen has some mechanisms to evade the immune system the
pathogen is not cleared by the mucociliery cscalatorThe pathogen secretes enzymes into the
lungs and causes damage. What is the most likely function of these enzymes and how are they
secreted? to kill competing sibling bacteria; secretion system to damage cells and release
nutrients; horizontal gene transfer to kill competing sibling bacteria; horizontal gene transfer to
damage cells and release nutrients; secretion system Question 12 2.5pts Humans are considered
a dead-end host for these bacteria, meaning there is no person-to-person: transmission. True or
false: the bacteria do not meet the requirements to be considered a pathogen. True false
