Bacteria ecology

Life History and Ecology Bacteria grow in a wide variety of habitats and conditions. When most people think of bacteria, they think of disease-causing organisms, like the Streptococcus bacteria growing in culture in this picture, which were isolated from a man with strep throat.

Bacteria ecology

Leeuwenhoek, a Dutch scientist, performed many experiments testing and observing bacteria. Biofilms are communities of bacteria, or micro-organismsattached to surfaces in the body. Oral biofilms are more commonly referred to as plaque. Biofilms form almost everywhere bacteria are.

In the mouth, they naturally form on any stationary surface, namely teeth, gums, and the tongue. Ecology and types[ edit ] The human mouth contains around to 1, different types of bacteria with various functions as part of the human flora and oral microbiology.

About to species may live in them at any given time. Streptococci make up a Bacteria ecology part of oral bacteria. Streptococcus mutans make up a large majority of what affects our mouths. For example, some of these bacteria produce organic acids that kill the organisms that cause intestinal problems.

Bacteria are also needed to control the growth of fungus. These bacteria are transmitted to a human early in their childhood through their contact with their caretakers by kisses or food premastication.

To grow Bacteria ecology flourish in the mouth, biofilms go through four main stages of growth. Then the bacteria, or micro-organisms, grow and replicate.

Since bacteria can grow exponentially in short periods of time, it can quickly and easily create biofilms. Third, the biofilm matures and accumulates more mass on the surface.

Bacteria can continue to divide and grow by binary fission until nutrients begin to run out or their growth is inhibited. Bacteria can then reattach and start to grow and the cycle continues.

Bacteria and its growth are two of the principal components of oral ecology. Saliva keeps the ecosystem of the mouth in balance. It contains its own bacterial enzymes that are beneficial to our health. An example of these are lysozomes. These antibacterial agents in saliva kill bacteria in our mouths and protect from potentially dangerous diseases.

Some of the proteins provide nutrients for bacteria, while others cause bacteria to clump together so they are unable to stick to any surface and are washed away. The main function of saliva is to flush out all of the micro-organisms that could potentially threaten our health.

Many harmful micro-organisms, therefore, are unable to attach quick enough to a surface before they are caught in saliva and swallowed.

Many diseases are related to oral bacteria. Proper oral care and habits can protect against and reduce the effects of some harmful bacteria. Some examples of the milder diseases passed through saliva include herpes simple virus cold sores or canker soresflu virus, cold virusand various bacteria that cause periodontal disease inflammation or infection of gum tissuevenereal diseasesand candida albicans fungus.

It is a contagious viral disease in the herpes virus family. Diseases related to oral hygiene[ edit ] Other serious and possibly life-threatening diseases have been found to be connected to oral hygiene.

Streptococcus mutans, a common oral bacteria discussed above, is a pathogen that causes pneumonia, sinusitis, otitis mediaand meningitis. Brushing and flossing teeth regularly are the most basic ways to reduce these risks. These two fundamental hygiene tips help to get rid of bacteria that try to stick to surfaces in our mouth to form plaque oral biofilms.

The less you brush your teeth, the better chance that bacteria will form plaque and potentially cause serious oral and health issues. This is true because much of the bacteria in our mouths are nourished by simple sugars and carbohydrates.

Visits to the dentist can be beneficial where fluoride treatments are available. Combined with dental sealantsthese treatments can, in most cases, ensure prevention of harmful bacterial effects. Chlorhexidine gluconate [mouthwash] rinses, when combined with toothbrushing, have been reported to reduce oral biofilms.

Toothbrush hygiene[ edit ] There are many ways to improve the oral cleaning process.Understanding Intestinal Bacteria – The Gut Ecology. Your body is home to a wide variety of creatures too small to see.

A large number of them live inside your gut and create a kind of inner zoo. Ecology publishes articles that report on the basic elements of ecological research. Emphasis is placed on concise, clear articles documenting important ecological phenomena.

The relationship between ß‐diversity of plants, bacteria and fungi (dissimilarity of communities) with elevation difference. ß‐diversity for all groups differed.

High bacteria levels in Puget Sound are a risk to human health. People can be exposed to illnesses when they swim and play in the water. In addition, shellfish are not safe to eat when bacteria levels are high.

Bacteria are the engine that keeps the entire ecosystem going. There is no part of any ecosystem that doesn’t fundamentally depend on some bacterial process.

Some examples: Bacteria play critical roles in the nitrogen cycle - on one end they captu. Microbial ecology (or environmental microbiology) is the ecology of microorganisms: their relationship with one another and with their environment. It concerns the three major domains of life— Eukaryota, Archaea, and Bacteria —as well as viruses.
