The fact that most of the human normal flora is composed of anaerobic bacteria suggests that anaerobic infections might be of medical concern. Indeed, anaerobic infections can occur in a variety of body sites and involve many different genera. Most of the normal anaerobic flora are not overtly pathogenic; rather, they are considered to be opportunistic. That is, if given the opportunity, they can inflict serious and occasionally life-threatening disease. These types of infections most often occur due to trauma, injury or surgery. In general, a loss of natural barriers that introduce these bacteria into normally sterile body sites may result in infection. The sites commonly involved in anaerobic infection include the following:
1. intraabdominal infections
2. pulmonary infections
3. pelvic infections
4. brain abscesses
5. skin and soft tissue
6. oral and dental infections
7. bacteremia and endocarditis
Treatment of these infections can sometimes be difficult but, generally, moderate to broad spectrum antibiotics are usually effective

Organisms that are anaerobic do not require oxygen to generate energy, while aerobic organisms do. Anaerobic organisms can generate energy through processes like fermentation, which is less efficient than aerobic respiration. Aerobic organisms can produce more energy because aerobic respiration is a more efficient process that requires oxygen.

Mycoplasma is an aerobic organism, meaning it requires oxygen to survive and grow.
Aerobic and Anaerobic environments.
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
An organism is described as anaerobic [from the Greek word "an" (opposite) and "aerobio" (air-lived)] if it does not require oxygen in order to survive. Instead, anaerobic organisms use anaerobic respiration to obtain energy from food. Most anaerobic organisms are microorganisms such as bacteria, yeasts, and internal parasites that live in places where there is never much oxygen, such as in the mud at the bottom of a lake or pond, or in the alimentary canal. Anaerobic organisms release much less of the available energy from their food than do aerobic organisms.
It may depend on the brand of blood culture bottles, but there are generally 2 types of bottles drawn on an adult patient; one to culture aerobic organisms and one for anaerobic or facultatively anaerobic organisms. Anaerobic organisms require no oxygen for growth. Facultative means the organism seems to do better under anaerobic conditions. AN for anaerobic...perhaps the F means facultatively.
Aerobic and Anaerobic Respiration.
An organism would perform anaerobic respiration when oxygen is not available or in limited supply. Anaerobic respiration allows organisms to continue generating ATP in the absence of oxygen by using alternative electron acceptors, such as nitrate or sulfate. One disadvantage of anaerobic respiration is that it is less efficient than aerobic respiration and can produce byproducts like lactic acid or ethanol.
An organism that is anaerobic does not require oxygen to survive. Instead, it uses other molecules, such as nitrate or sulfate, for energy production. This impacts its survival and metabolism by limiting the amount of energy it can produce compared to aerobic organisms. Anaerobic organisms are typically found in environments with low oxygen levels, such as deep ocean sediments or the human gut.
Aerobic respiration uses oxygen it is main source of energy in nearly all multicellular organisms and many unicellular animals.
Aerobic respiration requires oxygen to produce energy in the form of ATP, while anaerobic respiration does not require oxygen and produces energy through fermentation. Aerobic respiration is more efficient, producing more ATP molecules than anaerobic respiration.
