Final answer:
The statement that bacteria always enhance the replication of enteric viruses is false. The relationship between bacteria and enteric viruses is complex and does not always lead to enhanced viral replication. Viruses may enter latency or use the lytic cycle, rather than being consistently enhanced by bacteria.
Step-by-step explanation:
The statement that bacteria always enhance the replication of enteric viruses is false. While bacteria such as enteric bacteria of the family Enterobacteriaceae, which live in the human intestinal tract, sometimes interact with enteric viruses, they don't necessarily always enhance their replication. Viruses can undergo two types of replication cycles: the lytic cycle and the lysogenic cycle. In the lytic cycle, viruses reproduce rapidly and lyse the host cell to release new viruses. In contrast, the lysogenic cycle involves the integration of viral DNA into the host cell's genome, where it can remain dormant during unfavorable conditions.
Under unfavorable conditions, a virus may enter a latency period or, if it's in the form of a prophage within a bacterial cell, it may exit the genome and enter the lytic cycle, rather than being enhanced by the bacteria itself. Additionally, bacteria such as Escherichia coli (E. coli) that reside in our digestive tracts, are involved in nutrient absorption, but virulent strains can be pathogenic.
