Brachyspira Aalborgi
''Brachyspira aalborgi'' is a species of bacteria, one of the causative agents of intestinal spirochetosis. Its cells are anaerobic, sigmoidal with tapered ends, 2 to 6 μm long. Four flagella A flagellum (; : flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores ( zoospores), and from a wide range of microorganisms to provide motility. Many pr ... are inserted at each end of the cells. The maximal cell width is about 0.2 μm. The type strain is 513A (NCTC 11492).

Intestinal Spirochetosis
Human intestinal spirochetosis, often called just intestinal spirochetosis when the human context is implicit, is an infection of the colonic-type mucosa with certain species of spirochetal bacteria. Similar infections sometimes occur in pigs, dogs, and birds; porcine intestinal spirochaetosis is an economically important disease of livestock. Signs and symptoms No clear association exists with complaints. However, potential associations include abdominal pain and watery diarrhea, which may be seen with blood; however, these findings are not specific and may be due to a number of other causes. Cause Human intestinal spirochetosis is caused by '' Brachyspira pilosicoli'' and ''Brachyspira aalborgi''. Porcine and avian intestinal spirochetosis are caused by ''Brachyspira hyodysenteriae'' and ''Brachyspira pilosicoli''. Diagnosis It is diagnosed by examination of tissue, i.e., biopsy. A hallmark finding is the presence of a “false brush border” on the luminal surface of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Health Research Reviews
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Placozoa, Cni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flagellum
A flagellum (; : flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores ( zoospores), and from a wide range of microorganisms to provide motility. Many protists with flagella are known as flagellates. A microorganism may have from one to many flagella. A gram-negative bacterium '' Helicobacter pylori'', for example, uses its flagella to propel itself through the stomach to reach the mucous lining where it may colonise the epithelium and potentially cause gastritis, and ulcers – a risk factor for stomach cancer. In some swarming bacteria, the flagellum can also function as a sensory organelle, being sensitive to wetness outside the cell. Across the three domains of Bacteria, Archaea, and Eukaryota, the flagellum has a different structure, protein composition, and mechanism of propulsion but shares the same function of providing motility. The Latin word means " whip" to describe its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spirochaetes
A spirochaete () American and British English spelling differences#ae and oe, or spirochete is a member of the phylum (biology), phylum Spirochaetota (also called Spirochaetes ), which contains distinctive diderm bacteria, diderm (double-membrane) Gram-negative bacteria, most of which have long, spiral bacteria, helically coiled (corkscrew-shaped or spiraled, hence the name) cells. Spirochaetes are chemoheterotrophic in nature, with lengths between 3 and 500 μm and diameters around 0.09 to at least 3 μm. Spirochaetes are distinguished from other bacterial phyla by the location of their flagellum, flagella, called endoflagella, or periplasmic flagella, which are sometimes called ''axial filaments''. Endoflagella are anchored at each end (pole) of the bacterium within the periplasmic space (between the inner and outer membranes) where they project backwards to extend the length of the cell. These cause a twisting motion which allows the spirochaete to move. When rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
