What is superinfection and give example?
Superinfection is the process by which a cell that has previously been infected by one virus gets co-infected with a different strain of the virus , or another virus, at a later point in time. Viral superinfections may be resistant to the antiviral drug or drugs that were being used to treat the original infection.

HBV/HDV coinfection occurs when a person simultaneously becomes infected with both HBV and HDV, whereas HDV superinfection occurs when a person who is already chronically infected with HBV acquires HDV .
What is immunity to superinfection?
Superinfection immunity is typically associated with lysogeny and appears to be a consequence of the same mechanisms that prevent prophage induction. Ecologically, immunity serves to prevent bacteria from being infected by two or more related prophage, or to protect the lysogen from being lysed.
What is cross infection?
A cross infection is the transfer of harmful microorganisms, usually bacteria and viruses . The spread of infections can occur between people, pieces of equipment, or within the body. These infections can cause many complications. So, medical professionals work hard to ensure equipment safety and a clean environment.
What is the function of natural antibiotic production?
In the field of plant pathology, antibiotic-producing bacteria are used as a resource for new antifungal compounds and for biological control of pre- and postharvest diseases .
