'''Bacteria''' are single-celled microorganismslacking a [[nucleus]] or any other membrane-bound organelles. Modern [[pathology]] and [[medicine]] are based on the findings of [[Louis Pasteur]] and later [[Robert Koch]] and [[Charles Laveran]] that bacteria cause many ailments, but most microbes, in agreement with the benevolent nature of the [[Creator]], are actually beneficial to man and nature.<ref name="AiG Bacteria">[http://www.answersingenesis.org/articles/arj/v1/n1/microbes-days-of-creation Microbes and the Days of Creation], Answers: Research Journal.</ref> Bible scholars have dated their creation between Day 3 and 6 during Creation Week.<ref name="AiG Bacteria"/>
==Morphology of Bacteria== Bacteria are usually surrounded by a cell wall consisting of [[peptidoglycan]], and are filled with cytoplasm. Ribosomes within the cytoplasm are responsible for translating the circular bundle of DNA into functional proteins. Some bacteria, such as cyanobacteria, have tightly packed inner membrane folds, which forms a membrane across which photosynthesis can occur.<ref>http://www.ucmp.berkeley.edu/bacteria/bacteriamm.html</ref> ==Bacteria and Disease== Bacterial [[disease]] was a source of fear for humankind for most of [[history]]. This fear was largely abated by the development of [[antibiotic]] drugs in the last half of the 1900s. The general impression was that most bacterial diseases could be cured, relatively quickly and easily. But bacteria gain resistance to certain types of antibiotics, making their continued treatment in a recurrent infection difficult at times.<ref>[http://www.chemheritage.org/educationalservices/pharm/antibiot/readings/evolve.htm antibiot-readings]</ref> However, this is not evidence for the [[theory of evolution]], since the bacteria do not change from one type to another, they . They only gain or lose a few genes involved in the antibiotic , and no new information is created, in this process known as [[microevolution]] or adaptation. Bacterial disease is becoming a more serious medical problem, particularly in hospitals which tend to harbor a population of drug-resistant bacteria. ==Bacteria and Society==
Bacteria are tiny one-celled organisms present throughout the environment that require a microscope to be seen. The vast majority of bacteria are not harmful to human beings. Many of them are normally found on or in the human body, and not only do not cause disease, but provide some benefit. For example, the human gut normally contain a complement of ''intestinal flora'' which assist digestion.
