Ecology of Biofilms in Human Body and Other Living as Well as Non-living Substances

INTRODUCTION

Biofilms are nano ecosystems of several microbes lived in a close association to each other coated by slimy secretions of their bodies. Biofilms consist of several microorganisms those form a microbiotic community. The organisms (mainly bacteria) of different species form a mutual relationship with each other and are glued with the surface of the different parts of organisms' body including man, and different non-living substances of the world by a sticky secretion (Polysaccharides) of their bodies. The microbes have several strong adaptative features that provide them ample strength to struggle for their existence. Biofilms carry different pathogenic organisms those cause fatal infections in the human bodies and sometimes they are life threatened.

HISTORICAL BACKGROUND OF BIOFILMS

In 1994, near one hundred asthmatic people were died due to fatal infection caused by biofilms into their Lung tissues. They used the inhaler where biofilms were grown. Those biofilms had entered into their Lungs by respiratory tract and caused infection inside their Lungs. This phenomenon generated the idea about biofilms and immensely helped to introduce the ecology of biofilms as an important chapter of Microbiological science.

BIOFILMS IN THE ANIMAL BODY INCLUDING MAN

In the animal body biofilms are produced on the surface of Teeth, Intestines, Lungs, Liver and Kidneys etc. In those places biofilms form a layer of tiny bacteria and other larger organisms. In teeth the hard enamel provides a good environment for microorganisms. The food particles remaining at the buccal cavity get mixed with saliva provides a good ecosystem for the growing of different bacteria. Bacteria colony form slimy layers of biofilm also on different tracts of respiratory system, alimentary system, excretory system, reproductive system etc. Body surface of the domestic pets also provides good ecological factors for growing biofilms.
