Question

In a recent metagenomic study, the bacterial community found on human skin was characterized in individuals from seven households. For six weeks, samples were collected from the hands, feet, and noses of individuals, as well as from doorknobs, floors, and counters in each house. Bacterial rRNA was analyzed in the samples. During the study, the individuals from three households moved to new homes.
The following conclusions were made from the study:
• The similarity of the bacterial communities between individuals was positively correlated with their degree of physical contact.
• Individuals within a household shared a distinct bacterial community, and this community varied between households.
• The surfaces of the home displayed the same bacterial community as the occupants of the home.
• Bacteria were three times as likely to move from the skin of an individual to a surface, such as a doorknob, than from a household surface to the skin.
• When a house was left empty, the distinct bacterial signature of the previous occupants degraded within a few days.

Given this information, which of the following statements is consistent with the results of this study? Select all of the statements that apply.

a. The bacterial community of a family can colonize a new home.
b. An individual that visits a house will rapidly be colonized by the bacteria found within the house.
c. The bacterial communities of a husband and wife should be more similar than that of roommates who do not have a physically close relationship.
d. An individual's current home can be identified from the bacterial community found on their skin.
e. The human bacterial signature can be detected in a home that has been empty for years.
