Actinobacillosis
Actinobacillosis is a zoonotic disease caused by Actinobacillus. It is more commonly associated with animals than with humans. One of the most common forms seen by veterinarians is mouth actinobacillosis of cattle, due to ''Actinobacillus lignieresii''. The most prominent symptom is the swelling of the tongue that protrudes from the mouth and is very hard at palpation ("wooden tongue"). '' Actinobacillus suis'' is an important disease of pigs of all ages and can lead to severe morbidity and sudden death. Causes The infection is most commonly caused by abrasions on different soft tissues through which the bacteria, ''Actinobacillus lignieresii,'' enters. These soft tissues include subcutaneous tissues, the tongue, lymph nodes, lungs, and various tissues in the gastrointestinal tract. The injury results in different forms and locations of the disease depending on the location of the tissue. The commensal bacteria is also commonly found in the oral cavity, gastrointestinal trac ...

Actinobacillus Suis
''Actinobacillus suis'' is a beta-haemolytic, Gram-negative bacterium of the family Pasteurellaceae. The bacterium has many strains and is the pathogen responsible for actinobacillosis in pigs of all ages. It can also infect wild birds, domestic ruminants, dogs, cats, and horses. The organism can be found in the respiratory tract and tonsils of both infected and healthy pigs that act as carriers. Transmission is via the respiratory tract and piglets are usually infected early on in life. Herds with a high health status are more at risk and outbreaks can be explosive. Clinical signs and diagnosis Affected piglets can develop septicaemia, multifocal infections, and respiratory signs, and may die. Adult pigs may show signs relating to pneumonia, lethargy, anorexia, skin lesions similar to erysipelas, and sudden death. Diagnosis relies on the culture of sampled tissues to isolate the organism. Signs and necropsy findings may mimic diseases such as erysipelas, Glasser's disea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infectious Disease (medical Speciality)
Infectious diseases or ID, also known as infectiology, is a medical specialty dealing with the diagnosis and treatment of infections. An infectious diseases specialist's practice consists of managing nosocomial ( healthcare-acquired) infections or community-acquired infections and is historically associated with hygiene, epidemiology, clinical microbiology, travel medicine and tropical medicine. Scope Infectious diseases specialists typically serve as consultants to other physicians in cases of complex infections, and often manage patients with HIV/AIDS and other forms of immunodeficiency. Although many common infections are treated by physicians without formal expertise in infectious diseases, specialists may be consulted for cases where an infection is difficult to diagnose or manage. They may also be asked to help determine the cause of a fever of unknown origin. Specialists in infectious diseases can practice both in hospitals (inpatient) and clinics (outpatient).

Zoonotic
A zoonosis (; plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite or prion) that has jumped from a non-human (usually a vertebrate) to a human. Typically, the first infected human transmits the infectious agent to at least one other human, who, in turn, infects others. Major modern diseases such as Ebola virus disease and salmonellosis are zoonoses. HIV was a zoonotic disease transmitted to humans in the early part of the 20th century, though it has now evolved into a separate human-only disease. Most strains of influenza that infect humans are human diseases, although many strains of bird flu and swine flu are zoonoses; these viruses occasionally recombine with human strains of the flu and can cause pandemics such as the 1918 Spanish flu or the 2009 swine flu. ''Taenia solium'' infection is one of the neglected tropical diseases with public health and veterinary concern in ende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinobacillus
''Actinobacillus'' is a genus of Gram-negative, nonmotile and non-spore-forming, oval to rod-shaped bacteria occurring as parasites or pathogens in mammals, birds, and reptiles. It is a member of the family Pasteurellaceae. The bacteria are facultatively anaerobic or aerobic, capable of fermenting carbohydrates (without production of gas), and of reducing nitrates. The genomic DNA contains between 40 and 47 mol % guanine plus cytosine. ''Actinobacillus'' ('' Pasteurella'') ''ureae'' and ''A. hominis'' occur in the respiratory tracts of healthy humans and may be involved in the pathogenesis of sinusitis, bronchopneumonia, and meningitis. ''A. actinomycetemcomitans'' occurs in the human oral microflora, and together with anaerobic or capnophilic organisms ( HACEK group organisms) may cause endocarditis. Actinobacilli are susceptible to most antibiotics of the beta-lactam family, aminoglycosides, tetracyclines, chloramphenicol, and many other antibacterial chemotherapeut ...

Veterinarian
A veterinarian (vet), also known as a veterinary surgeon or veterinary physician, is a medical professional who practices veterinary medicine. They manage a wide range of health conditions and injuries in non-human animals. Along with this, vets also play a role in animal reproduction, animal health management, conservation, husbandry and breeding and preventive medicine like animal nutrition, vaccination and parasitic control as well as biosecurity and zoonotic disease surveillance and prevention. Description In many countries, the local nomenclature for a veterinarian is a regulated and protected term, meaning that members of the public without the prerequisite qualifications and/or licensure are not able to use the title. This title is selective in order to produce the most knowledgeable veterinarians that pass these qualifications. In many cases, the activities that may be undertaken by a veterinarian (such as treatment of illness or surgery in animals) are restricted only t ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus ''Bos''. Adult females are referred to as cows and adult males are referred to as bulls. Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather. They are used as riding animals and draft animals ( oxen or bullocks, which pull carts, plows and other implements). Another product of cattle is their dung, which can be used to create manure or fuel. In some regions, such as parts of India, cattle have significant religious significance. Cattle, mostly small breeds such as the Miniature Zebu, are also kept as pets. Different types of cattle are common to different geographic areas. Taurine cattle are found primarily in Europe and temperate areas of Asia, the Americas, and Australia. Zebus (also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tongue
The tongue is a muscular organ (anatomy), organ in the mouth of a typical tetrapod. It manipulates food for mastication and swallowing as part of the digestive system, digestive process, and is the primary organ of taste. The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of oral hygiene, cleaning the teeth. A major function of the tongue is the enabling of speech in humans and animal communication, vocalization in other animals. The human tongue is divided into two parts, an oral cavity, oral part at the front and a pharynx, pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of connective tissue, fibrous tissue (the lingual septum) that results in a groove, the median sulcus, on the tongue's surface. There are two groups of muscle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinomycosis In Animals
Actinomycosis is an infection caused by a bacterium of the genus '' Actinomyces'', usually '' Actinomyces bovis''; the disease it causes has several common names. When it is a moveable tumour or lump on the jaw area, it is referred to as lump jaw; when it spreads into the hard bone of the jaw, it is referred to as big jaw; and when it affects the tongue, it is referred to as wooden tongue. Actinomycosis in cattle Actinomycosis is a common condition in weaned calves, young bulls, and heifers. The disease has a chronic course, and the general body condition can remain quite good. Swelling in the area of the maxilla and mandible occurs. Fistulization A fistula (plural: fistulas or fistulae ; from Latin ''fistula'', "tube, pipe") in anatomy is an abnormal connection between two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow org ... occurs after some days, leaving a thick, yellowish, nonodorous pus, with mine ...

Sodium Iodide
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na+) and iodide anions (I−) in a crystal lattice. It is used mainly as a nutritional supplement and in organic chemistry. It is produced industrially as the salt formed when acidic iodides react with sodium hydroxide. It is a chaotropic salt. Uses Food supplement Sodium iodide, as well as potassium iodide, is commonly used to treat and prevent iodine deficiency. Iodized table salt contains 10 ppm iodide. Organic synthesis Sodium iodide is used for conversion of alkyl chlorides into alkyl iodides. This method, the Finkelstein reaction, relies on the insolubility of sodium chloride in acetone to drive the reaction: ::R–Cl + NaI → R–I + NaCl Nuclear medicine Some radioactive iodide salts of sodium, including Na 125I and Na 131I, have radioph ...

Actinomycosis
Actinomycosis is a rare infectious bacterial disease caused by ''Actinomyces'' species. The name refers to ray-like appearance of the organisms in the granules. About 70% of infections are due to either ''Actinomyces israelii'' or '' A. gerencseriae''. Infection can also be caused by '' Streptomyces somaliensis'' and '' Propionibacterium propionicus''. The condition is likely to be a polymicrobial anaerobic infection. Signs and symptoms The disease is characterised by the formation of painful abscesses in the mouth, lungs, breast, or gastrointestinal tract. Actinomycosis abscesses grow larger as the disease progresses, often over months. In severe cases, they may penetrate the surrounding bone and muscle to the skin, where they break open and leak large amounts of pus, which often contains characteristic granules filled with progeny bacteria. These granules are often called "sulfur granules" due to their yellow appearance, although they may also be white, gray or brown. Causes ...
