Question

Viruses, bacteria and fungi multiply very quickly, while worms multiply very slowly in
comparison. Taxonomically, all bacteria are closely related to each other than to viruses and vice
versa. This means that many important life processes are similar in the bacteria group but are not
shared with the virus group. They commonly block biochemical pathways important for bacteria.
Many bacteria, for example, make a cell-wall to protect themselves. The antibiotic penicillin
blocks the bacterial processes that build the cell-wall. Penicillin will have this effect on any
bacteria that use such processes for making cell-walls. Similarly, many antibiotics work against
many species of bacteria rather than simply working against one. But viruses do not use these
pathways at all, and that is the reason why antibiotics do not work against viral infections. If we
have a common cold, taking antibiotics does not reduce the severity or the duration of the disease.
However, if we also get a bacterial infection along with the viral cold, taking antibiotics will help.
Even then, the antibiotic will work only against the bacterial part of the infection, not the viral
infection. The sexual act is one of the closest physical contact two people can have with each other.
Not surprisingly, there are microbial diseases such as syphilis or AIDS that are transmitted by
sexual contact from one partner to the other.
