What is anaerobic bacteria (with pictures) electricity experiments for high school


Anaerobic bacteria, or anaerobes, are bacteria that do not need oxygen to live. In humans, these gas unlimited houston texas bacteria generally live in the gastrointestinal tract, but they may also be found in other places outside the body, including in the soil and water, in foods, and in animals. Some anaerobes are beneficial to humans, but others can cause illnesses, such as appendicitis, diverticulitis, and gingivitis. Characteristics of an anaerobic bacterial infection are bad-smelling pus, the formation of abscesses, and the destruction of tissue. Beneficial or Harmful

The Bacteroides genus is an example of anaerobic la gasolina mp3 bacteria that is both beneficial and harmful. In the gastrointestinal tract, species from this genus aid digestion, but when in other areas of the body, they can cause sinus thrombosis, pneumonia, and meningitis, among other gas zeta costa rica illnesses. Other anaerobes help people without living in their bodies. For example, some species of Lactobacillus are commonly used in cheese making. Likewise, some types of Clostridium can be used in bioremediation, which is the process of making contaminated soil usable again; they do this by attacking contaminates and converting them into nontoxic carbon dioxide.

There are three categories of anaerobic bacteria gas stoichiometry worksheet answers: obligate, aerotolerant, and facultative. Obligate anaerobes need an oxygen-free environment to live. They cannot grow in places with oxygen, which can sometimes damage and destroy them. Aerotolerant bacteria do not use oxygen to live, but can exist in its presence. Facultative gas welder salary anaerobes use fermentation to grow in places without oxygen, but use aerobic respiration in places with oxygen.

Porphyromonas gingivalis is an example of an obligate anaerobe. It’s commonly found in the mouth, but is also thought to be connected with rheumatoid arthritis. A common example of an aerotolerant anaerobic bacteria is Propionibacterium acnes. It normally exists on people’s skin, and is a contributing factor to acne. In some electricity png cases, it enters the body and causes endocarditis, which is an inflammation of the heart lining.

Some species in the Staphylococcus genus are facultative, and are a leading cause of blood poisoning. One example is Staphylococcus aureus, which produces a range of infections from common skin problems like acne, boils, and impetigo youtube gas pedal dance to acute conditions like meningitis, endocarditis, and pneumonia. It also causes toxic shock syndrome (TSS). Another facultative anaerobe is Escherichia coli, which contains many helpful strains of bacteria as well as some electricity 1 7 pdf damaging ones, such as those that cause food poisoning. Anaerobic Infections

Other anaerobes, such as those in the Actinomyces genus, can cause dental infections within the mouth. Mouth injuries, surgeries, or diseases can allow normally benign anaerobic bacteria to develop into infections, causing abscesses, pain, and inflammation. Rinsing with hydrogen peroxide releases oxygen, which can gas and supply help destroy bacteria or slow its growth. Anaerobic mouth infections can also occur in the root canals, jaw, tonsils, and throat.

Sometimes anaerobes infect the lungs, causing abscesses, pneumonia, purulent pleurisy, and dilated lung bronchi. Other times they affect the abdomen, causing peritonitis and abscesses. Several species can be found throughout the body; for example, species in the Actinomyces genus generally appear in the electricity powerpoint template oral cavity and upper respiratory tract, but may exist in the gastrointestinal tract. Other species live in specific areas, such as the colon. Bacteroides species are typically found in human feces, and cause tissue destruction electricity recruitment 2015 when introduced into a wound. Symptoms of Infection

A person with a throat infection may have a sore throat, choking sensation, or fever, along with bad breath. People with lung infections may have difficulty breathing, as well as a cough, chest pain, and fever. Those with abdominal infections may experience fever and pain. If a person recently underwent surgery, there may gas giants be foul-smelling drainage from his or her wound. Pelvic infections generally cause pain, fever, chills, and drainage from the uterus.

Anaerobic bacterial infections in skin wounds generally appear as red, swollen areas, and they may secrete 9game foul-smelling pus. Bloodstream infections often cause chills and high fevers, and can ultimately result in death. People with blood poisoning usually have red streaks in the skin near the wound, even if the wound does not appear to be infected electricity and magnetism equations. Risk Factors

It is sometimes hard to know where a person contracted a bacteria-based illness. For example, bacteria spores in the Clostridium genus, which can cause tetanus, botulism, and gas gangrene, can live for a long time in harsh conditions before they germinate and grow. Many cases of infection are caused by several types of anaerobic bacteria working together. Common Shapes

Anaerobes gas in back and chest have many shapes. Actinomyces have rod shapes that may be straight, slightly curved, or branched. Propionibacterium also come in several shapes, such as oval, club-shaped, or rod-shaped, as well as branched and forked. Doctors and researchers use shape as one of the identifying factors when diagnosing a patient or studying a bacterium.
