A student complains that it makes no sense to worry about coliform bacteria in water, since we naturally possess harmless colifo

rms in our intestines anyway. Why do regulatory agencies worry about coliform bacteria in water supplies, then?

Answer:

Some types of coliform bacteria can cause death if ingested.

Explanation:

We have coliform bacteria as part of our bacterial flora. Most coliform bacteria are not harmful. However, there are some strains such as E. coli (Escherichia coli) that can cause serious diseases. Hemolytic Uremic Syndrome is one of them. Bacteria can be found in contaminated water, poorly washed vegetables and raw meats.

When an E. coli cell is infected by multiple phages, what route of infection (lytic or lysogenic) will the phages take? Why?
Artyom0805 [142]

Answer:

When an E.coli cell is infected by multiple phages,they will take either lytic or lysogenic pathway.

Explanation:

When lambda phage bacteriophage infects an E.coli,it can either undergo lytic cell growth and lyse the host cell or enter lysogenic pathway.

The operator region of lac operon in E.coli contain single repressor binding site whereas the lambda operators O_{L} and O_{R}  each contains 3 repressor binding sites (O_{L_1} ,    O_{L_2},O_{L_3} and O_{R_1},O_{R_2},O_{R_3})  that are differently occupied under different conditions.

The differential affinity of lambda repressor for the three binding sites in these operators play an important role in the maintenance of lysogenic state of lambda prophage in E.coli.

The lytic development occurs in cells infected with lambda phage that carry  C_1 gene.

In contrast,lysogeny will occur in bacteria that infected with lambda phage that harbor a deletion of Cro gene.
