The American Society for Microbiology (ASM) is a professional organization for scientists who study viruses, bacteria, fungi, algae, and protozoa as well as other aspects of microbiology. Microbiology is the study of organisms too small to be seen with the naked eye and which must be viewed with a microscope. ASM membership includes scientists who do basic research into the nature and lives of viruses, bacteria, and other microorganisms. ASM membership also includes scientists who work in the field of applied microbiology, for example, researching cures for diseases caused by microorganisms, or the potential for microorganisms to create cheeses from milk, to generate fuels, or to clean up oil spills.

ASM was founded in 1899 under the name the "Society of American Bacteriologists." In December 1960, it was renamed the "American Society for Microbiology."

According to the ASM website , the mission of the American Society for Microbiology is to:

The society or culture of the United States is a Western culture, and has been developing since long before the United States became a country with its own unique social and cultural characteristics such as dialect, music, arts, social habits, cuisine, folklore, etc. Today the United States of America is an ethnically and racially diverse country as result of large-scale immigration from many different countries throughout its history .

Its chief early influences came from English and Irish settlers of colonial America. British culture, due to colonial ties with Britain that spread the English language, legal system and other cultural inheritances, had a formative influence. Other important influences came from other parts of western Europe.

The United States has often been thought of as a melting pot, but recent developments tend towards cultural diversity, pluralism and the image of a salad bowl rather than a melting pot. Due to the extent of American culture there are many integrated but unique social subcultures within the United States. The cultural affiliations an individual in the United States may have commonly depend on social class, political orientation and a multitude of demographic characteristics such as religious background, occupation and ethnic group membership. The strongest influences on American culture came from northern European cultures, most prominently from Britain, Ireland, and Germany.

A society, or a human society, is a group of people related to each other through persistent relations, or a large social grouping sharing the same geographical or virtual territory, subject to the same political authority and dominant cultural expectations. Human societies are characterized by patterns of relationships (social relations) between individuals who share a distinctive culture and institutions; a given society may be described as the sum total of such relationships among its constituent members. In the social sciences, a larger society often evinces stratification and/or dominance patterns in subgroups.

Insofar as it is collaborative, a society can enable its members to benefit in ways that would not otherwise be possible on an individual basis; both individual and social (common) benefits can thus be distinguished, or in many cases found to overlap.

A society can also consist of like-minded people governed by their own norms and values within a dominant, larger society. This is sometimes referred to as a subculture, a term used extensively within criminology.
