Answer:

A

The enterobacteriaceae group (enteric bacteria) are bacteria found only in the intestine. Enteric literally means intestine. They are gram negative bacilli that are non- spore forming, most are motile. The consist of many genera and strains that colonize the small and large intestine and includes members of the non-pathogenic autochthonous (bacteria that are native species of the intestine, they are neither hurting nor helping  the system) microbiota as well as pathogens. Examples of the pathogens include some strains of Escherichia coli, Salmonella typhii, Shigella spp. Examples of the non-pathogenic enteric bacteria includes Lactobacillus acidophillus and some strains of Escherichia coli.
