All animals contain microbes, often billions of them.The symbiosis between the host and its microbes is essential for the well-being of the animal. Two examples of this show how important it is. If one is eating antibiotics, the gut microflora becomes disturbed, and, e.g., diarrhea can be the result. Ruminants utilize bacteria for digesting grass. Because of the fact that microbes are affected by completely different toxins than their animal hosts, surprising effects of environmental pollutants can be observed. For example, some herbicides may affect the necessary microbes of man, and because of this, although the effective compound does not exert any toxicity on the animal itself, by disturbing the microbial community of the animal, it may influence its well being. Effects of environmental pollution on the microbiota of animals is so far poorly studied - and is undoubtedly one area, which will receive important attention in the future.
