Caprine Arthritis Encephalitis
Caprine arthritis encephalitis (CAE) is a viral disease of goats caused by a lentivirus called caprine arthritis encephalitis virus. The disease is found worldwide. Two syndromes of CAE occur. Adult goats develop a chronic progressive arthritis, whereas young goats develop a neurological syndrome, with signs of paresis or paralysis. Less commonly, mastitis or pneumonia may occur. Infection is life-long, and it may be years before signs of the disease occur. The reason for the long (and variable) period of dormancy of the virus is not known. In goats which develop arthritis, the joints become inflamed and swollen, and the goats will slowly lose condition. In some cases the goat will not be able to stand. In goats which develop the neurological form of the disease, the onset of signs is gradual over several weeks. The hind legs are most often affected. The goat will be uncoordinated, and unable to place its feet properly, so that it "knuckles", that is, it stands with the ...

Caprine Arthritis Encephalitis Virus
Caprine arthritis encephalitis virus (CAEV) is a retrovirus which infects goats and cross-reacts immunologically with HIV, due to being from the same family of viruses. CAEV cannot be transmitted to humans, including through the consumption of milk from an infected goat. There is no evidence that CAEV can cure HIV in humans. CAEV is commonly transferred within the goat species by ingestion of colostrum or milk from an infected goat, and to a lesser extent, cross-species CAEV transfer by sheep is possible. Symptoms CAEV adversely affects the immune system of its host, causing a disease known as caprine arthritis encephalitis. Common symptoms resulting from CAEV infection include arthritis, pneumonia, indurative mastitis, and encephalitis Encephalitis is inflammation of the Human brain, brain. The severity can be variable with symptoms including reduction or alteration in consciousness, aphasia, headache, fever, confusion, a stiff neck, and vomiting. Complications may incl ...

Virus
A virus is a submicroscopic infectious agent that replicates only inside the living Cell (biology), cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 16,000 of the millions of List of virus species, virus species have been described in detail. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent viral particles, or ''virions'', consisting of (i) genetic material, i.e., long ...

Lentivirus
''Lentivirus'' is a genus of retroviruses that cause chronic and deadly diseases characterized by long incubation periods, in humans and other mammalian species. The genus includes the human immunodeficiency virus (HIV), which causes AIDS. Lentiviruses are distributed worldwide, and are known to be hosted in apes, cows, goats, horses, cats, and sheep as well as several other mammals. Lentiviruses can integrate a significant amount of viral complementary DNA into the DNA of the host cell and can efficiently infect nondividing cells, so they are one of the most efficient methods of gene delivery. They can become endogenous, integrating their genome into the host germline genome, so that the virus is henceforth inherited by the host's descendants. Classification Five serogroups of lentiviruses are recognized, reflecting the vertebrate hosts with which they are associated (primates, sheep and goats, horses, domestic cats, and cattle). The primate lentiviruses are distinguished ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Arthritis
Arthritis is a general medical term used to describe a disorder that affects joints. Symptoms generally include joint pain and stiffness. Other symptoms may include redness, warmth, Joint effusion, swelling, and decreased range of motion of the affected joints. In certain types of arthritis, other organs such as the skin are also affected. Onset can be gradual or sudden. There are several types of arthritis. The most common forms are osteoarthritis (most commonly seen in weightbearing joints) and rheumatoid arthritis. Osteoarthritis usually occurs as an individual ages and often affects the hips, knees, shoulders, and fingers. Rheumatoid arthritis is an autoimmune disorder that often affects the hands and feet. Other types of arthritis include gout, lupus, and septic arthritis. These are inflammatory based types of rheumatic disease. Early treatment for arthritis commonly includes resting the affected joint and conservative measures such as heating or icing. Weight Weight ...

Paresis
In medicine, paresis (), compound word from Greek , (πᾰρᾰ- “beside” + ἵημι “let go, release”), is a condition typified by a weakness of voluntary movement, or by partial loss of voluntary movement or by impaired movement. When used without qualifiers, it usually refers to the limbs, but it can also be used to describe the muscles of the eyes ( ophthalmoparesis), the stomach (gastroparesis), and also the vocal cords ( vocal cord paresis). Neurologists use the term ''paresis'' to describe weakness, and ''plegia'' to describe paralysis in which all voluntary movement is lost. The term ''paresis'' comes from the 'letting go' from παρίημι 'to let go, to let fall'. Types Limbs * Monoparesis – One leg or one arm * Paraparesis – Both legs * Hemiparesis – The loss of function to only one side of the body * Triparesis – Three limbs. This can either mean both legs and one arm, both arms and a leg, or a combination of one arm, one leg, and face * ...

Paralysis
Paralysis (: paralyses; also known as plegia) is a loss of Motor skill, motor function in one or more Skeletal muscle, muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed with some form of permanent or transient paralysis. The word "paralysis" derives from the Greek language, Greek παράλυσις, meaning "disabling of the nerves" from παρά (''para'') meaning "beside, by" and λύσις (''lysis'') meaning "making loose". A paralysis accompanied by involuntary tremors is usually called "palsy". Causes Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, Physical trauma, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson's disease, ALS, botulism, spina bifida, multiple sclerosis and Guillain–Barré syndrome.

Mastitis
Mastitis is inflammation of the breast or udder, usually associated with breastfeeding. Symptoms typically include local pain and redness. There is often an associated fever and general soreness. Onset is typically fairly rapid and usually occurs within the first few months of delivery. Complications can include abscess formation. Risk factors include poor latch (breastfeeding), latch, cracked nipples, and weaning. Use of a breast pump has historically been associated with Mastitis, but has been determined as an indirect association. The bacteria most commonly involved are ''Staphylococcus'' and ''Streptococci''. Diagnosis is typically based on symptoms. Ultrasound may be useful for detecting a potential abscess. Prevention of this Breastfeeding difficulties, breastfeeding difficulty is by proper breastfeeding techniques. When infection is present, antibiotics such as cephalexin may be recommended. Breastfeeding should typically be continued, as emptying the breast is import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pneumonia
Pneumonia is an Inflammation, inflammatory condition of the lung primarily affecting the small air sacs known as Pulmonary alveolus, alveoli. Symptoms typically include some combination of Cough#Classification, productive or dry cough, chest pain, fever, and Shortness of breath, difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and Microbiological culture, culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, ...

Colostrum
Colostrum (, of unknown origin) is the first form of milk produced by the mammary glands of humans and other mammals immediately following delivery of the newborn. Animal colostrum may be called beestings, the traditional word from Old English dialects. Most species will begin to generate colostrum just prior to giving birth. Colostrum contains Antibody, antibodies to protect the newborn against disease and infection, and immune and growth factors and other bioactive compounds, bioactives. The bioactives found in colostrum are beneficial for a newborn's health, growth and vitality. Colostrum strengthens a baby's immune system. At birth, the environment of the newborn mammal shifts from the sterile conditions of the mother's uterus, with a constant nutrient supply via the placenta, to the microbe-rich environment outside, with irregular oral intake of complex milk nutrients through the gastrointestinal tract. This transition puts high demands on the gastrointestinal tract of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pasteurization
In food processing, pasteurization (American and British English spelling differences#-ise, -ize (-isation, -ization), also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than , to eliminate pathogens and extend shelf life. Pasteurization either destroys or deactivates microorganisms and enzymes that contribute to food spoilage or the risk of disease, including vegetative bacteria, but most Endospore, bacterial spores survive the process. Pasteurization is named after the French microbiologist Louis Pasteur, whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries for food preservation and food safety. By the year 1999, most liquid products were heat treated in a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
