Omasitis
Omasitis is an inflammation of the omasum, the third compartment of the stomach in ruminants. It usually accompanies rumenitis, and is often caused by infection with ''Fusobacterium necrophorum ''Fusobacterium necrophorum'' is a species of bacteria responsible for Lemierre's syndrome and other medical problems. Biology ''F. necrophorum'' is a rod-shaped species of Gram-negative bacteria. It is an obligate anaerobe and is a common inha ...''.

Omasum
The omasum, also known as the bible, the fardel, the manyplies and the psalterium, is the third compartment of the stomach in ruminants. The omasum comes after the rumen and reticulum and before the abomasum. Different ruminants have different omasum structures and function based on the food that they eat and how they developed through evolution. Anatomy The omasum can be found on the right side of the cranial portion of the rumen. The omasum receives food from the reticulum through the reticulo-omasal orifice and provides food to the abomasum through the omaso-abomasal orifice. The omasum is spherical to crescent shape and has multiple leaflets similar to that of a book called omasal laminae. The omasal laminae are made of thin muscular layers covered with a nonglandular mucous membrane. The omasal laminae come from the sides of the large curvature and project towards the inside of the omasum, extending from the reticulo-omasal orifice to the omaso-abomasal orifice. The lamina ...

Ruminant
Ruminants (suborder Ruminantia) are ungulate, hoofed herbivorous grazing or browsing mammals that are able to acquire nutrients from plant-based food by Enteric fermentation, fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.

Fusobacterium Necrophorum
''Fusobacterium necrophorum'' is a species of bacteria responsible for Lemierre's syndrome and other medical problems. Biology ''F. necrophorum'' is a rod-shaped species of Gram-negative bacteria. It is an obligate anaerobe and is a common inhabitant of the alimentary tract within humans and animals. Pathogenicity ''F. necrophorum'' is responsible for 10% of acute sore throats, 21% of recurrent sore throats and 23% of peritonsillar abscesses with the remainder being caused by Group A streptococci or viruses. Other complications from ''F. necrophorum'' include meningitis, complicated by thrombosis of the internal jugular vein, thrombosis of the cerebral veins, and infection of the urogenital and the gastrointestinal tracts. Although this infection is rare, researchers agree that this diagnosis should be considered in a septicaemic patient with thrombosis in an unusual site, and underlying malignancy should be excluded in cases of confirmed ''F. necrophorum'' occurring at sites ...

Stomach Disorders
The stomach is a muscular, hollow organ in the gastrointestinal tract of humans and many other animals, including several invertebrates. The stomach has a dilated structure and functions as a vital organ in the digestive system. The stomach is involved in the gastric phase of digestion, following chewing. It performs a chemical breakdown by means of enzymes and hydrochloric acid. In humans and many other animals, the stomach is located between the oesophagus and the small intestine. The stomach secretes digestive enzymes and gastric acid to aid in food digestion. The pyloric sphincter controls the passage of partially digested food (chyme) from the stomach into the duodenum, where peristalsis takes over to move this through the rest of intestines. Structure In the human digestive system, the stomach lies between the oesophagus and the duodenum (the first part of the small intestine). It is in the left upper quadrant of the abdominal cavity. The top of the stomach lies against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
