Enrichment of sewage samples is necessary for the isolation of phages because it increases the concentration of phages specific to the target bacteria, improving the chances of recovery. Sewage contains a diverse microbial community, and enrichment helps to selectively amplify the phage population that can infect the desired host bacteria. Additionally, this process can enhance the viability of phages by providing optimal growth conditions for both bacteria and phages, leading to a more successful isolation.
Isolation Is necessary for speciation to occur.
Isolation or reproductive barrier is necessary in the formation of a new species. This can occur through geographical isolation, behavioral differences, or genetic mutations that prevent interbreeding between populations.

I wouldn't call bacteriophages parasites, but yes they are viruses which infect bacteria.

Bacteriophages are, quite literally, "bacteria eaters". Bacteriophages are a type of virus that attacks bacteria, taking over its cell to reproduce.
called bacteriophages. They are viruses that specifically infect and replicate within bacteria, ultimately leading to the death of the host cell. Bacteriophages play a crucial role in controlling bacterial populations in various environments.
Bacteriophages can be obtained from specialized laboratories that provide specific bacteriophage products or services. They can also be isolated from environmental samples by collecting samples from natural sources and using techniques to identify and isolate bacteriophages that infect specific bacteria. Additionally, bacteriophages can be purchased from culture collections that store and distribute various strains of bacteriophages for research and therapeutic purposes.
Bacteriophages are viruses that infect and replicate within bacteria. They do not infect human cells or other eukaryotic organisms. Bacteriophages are specific to infecting particular bacterial species or strains.
