How long does it take the body to create antibodies after it is exposed to a disease?

It depends mostly on: ..the disease itself. Many acute infections produce antibodies in just a few days. Hepatitis B antibodies take longer. Some infections,, like HIV/AIDS, can take weeks, even a few months.. When we interpret results of antibody testing, we take this delay into account. Sometimes we can test for the infection itself & don't have to wait for antibodies to appear. Hope this info helps.

Several weeks: Antibody production can take several weeks and the first antibodies fall into the category of IgM Immunoglobulins. Several weeks to months after IgM is detected a second category of IgG immunoglobulins is formed. see http://biology.about.com/od/molecularbiology/ss/antibodies.htm

Quickly but: To really notice it may take days depending on the type of microbe. FYI: IgM rises quickly while IgG antibodies can take 3-4 weeks to peak. Not all microbes are fought off by antibodies but rather by the immune systems cells.
