Cyanobacteria

Cyanobacteria

Cyanobacteria is a phylum of bacteria that can obtain its energy through photosynthesis. The name “cyanobacteria” stems from the color of the bacteria used in Greek. This bacteria is often referred to as blue-green algae but some consider the name to be a misinterpretation because cyanobacteria are prokaryotic abd algae are typically eukaryotic even though some definitions of algae encompassprokaryotic organisms. Cyanobacteria are thought to have converted the earth’s reducing atmosphere into an oxidizing one, which changed the composition of life form on our planet.…

Aquificae

The Aquificae phylum is a diverse collection of bacteria that live in hostile environments. They have been located in ho springs, sulfur pools and even thermal ocean vents. These bacteria thrive at 86-95ºC making them some of the most thermophilic bacteria known. They are autotrophs and also the primary carbon fixers in these environments. Members of this group appear to be restricted to geothermal habitats, where they live by splitting hydrogen gas of hydrogen sulfide and fixing carbon dioxide for carbon. The Aquificae include halophiles…

Fusobacteria

Fusobacteria

What is fusobacteria? Fusobacteria is an anaerobic gram-negative rod that is a rare cause of serious human disease. Two Fusobacterium species, Fusobacterium nucleatum and fusobacterium necrophorum, are the most commonly isolated pathogens within this genus. In 1936, Andre Lemierre described cases of oropharyngeal infection followed by septic thrombophlebitis of the internal jugular vein with sepsis syndrome and metastatic disease, typically to the lungs. Fusobacterium necrophorum was identified as the causal agent of this condition. Carriage of F. necrophorum in the oropharynx of healthy young adults…

Actinobacteria

Actinobacteria

Whhat is Actinobacteria? Actinobacteria are a group of Gram-positive bacteria with a high guanine and cytosine content in their DNA. The guanine and cytosine content of Actinobacteria, can be as high as 70% but some of them do have low guanine and cytosine content. There are two types of actinabacteria and they are terrestrial or aquatic. Even though people understand them as soil bacteria, they might be more abundant in freshwater. Actinobacteria is one of the dominant bacterial phyla and it also contains one of…

Probiotic Combinations

The following is a list of probiotics that are combined and which functions they perform. L. acidophilus, L.rhamnosusMany researches believe the myriad health benefits of L. acidophilus are also attributable to L. rhamnosus. These two species are perhaps the most important Lactobacili in the small intestine. E. faeciumThis probiotic has become quite popular with health professionals over the years because of the proventherapeutic value of E. faecium. This species seems to be a strong defence againsa variety of pathogenic organisms. Several studies have proven that…

Probiotics

Probiotics

What are Probiotics? There are billions of bacteria living in the digestive system of every human, many of which are “friendly” bacteria that contribute to the health and balance of the intestinal tract. This normal microflora prevents the overgrowth of potentially pathogenic bacteria in the intestinal tract. Sometimes, due to viral or bacterial infections, diet, lifestyle changes, antibiotic use, and other factors, the normal bacteria in our intestinal tract become depleted, allowing the potentially pathogenic bacteria to overgrow. The result may be diarrhea, gas, or…

History of bacteriology

History of bacteriology

Bacteria were first absorbed by a Dutch microscopist, Antonie van Leeuwenhoek back in 1676. He used a single-lens microscope that he developed on his own. His observations were published in a series of letters to the Royal Society of London. Bacteria were van Antonie’s most remarkable microscopic discovery. At the time, these cells were at the limit of what his microscope could make out and the strangest thing is that nobody saw those bacteria again for roughly a century. It was only then, that his…

Pathogenic Bacteria

Pathogenic bacteria are bacteria that can cause diseases. Even though most bacteria are harmless or beneficial, there are several that are a threat o use. This form of bacteria contributes significantly to other globally important diseases like pneumonia and foodborne illnesses. How pathogenic bacteria cause disease. Conditionally pathogenic. Conditionally pathogenic bacteria are only pathogenic under certain conditions such as wounds or a decrease in immune function. Some species of pathogenic bacteria are opportunistic pathogens that cause disease mainly in people suffering from immunosuppression or cystic…

Archaea

Archaea

What are archaea? Archae is a domain or kingdom of single-celled microorganisms. These organisms are called prokarytoes. They have no cell nucleus or any membrane-bound organelles in their cells. Classification: The Archaea was first classified as bacteria and they received the name archaebacteria. Nowadays, this classification is outdated. Their cells have unique properties that separate them from the other two domains of life. Bacteria. Eukaryota. Now, this domain consists if four recognized phyla. The classification of these organisms are difficult because the majority have not…
