Canine Demodicosis
Canine demodicosis is a common Parasitism, parasitic skin disease in Canidae, dogs caused by the excessive proliferation of the hair follicle mite ''Demodex canis''. It can occur locally or all over the body. Demodicosis in older animals only occurs in connection with disorders of the immune system, in young animals the development of the disease is not fully understood. Demodicosis usually begins with hair loss and without itching. As the disease progresses, a secondary bacterial infection can lead to severe skin changes up to purulent skin inflammation (pyoderma). The disease is detected by microscopic detection of mites. Treatment is carried out with Acaricide, mite-effective medication. Cause of illness Demodicosis is mainly triggered by ''Demodex canis''. ''Demodex canis'' is a slender mite, about 250 to 300 micrometers long and 40 micrometers thick, which parasitizes the Hair, hair follicles and sebaceous glands. There it feeds on sebum, tissue fluid and the naturally reje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymph (biology)
In biology, a nymph (from Ancient Greek wikt:νύμφα, νύμφα ''nūmphē'' meaning "bride") is the juvenile (organism), juvenile form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (biology), metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species) and the emergence of genitalia. In addition, while a nymph ecdysis, moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. Taxa with nymph stages Many species of Arthropod, arthropods have nymph stages. This includes the insect orders such as Orthoptera (cricket (insect), crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, Whitefly, whiteflies, aphids, leafhoppers, froghoppers, treehoppers), mayfly, mayflies, termites, cockroaches, mantises, ...

Zoonosis
A zoonosis (; plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a virus, bacterium, parasite, fungi, or prion) that can jump from a non-human vertebrate to a human. When humans infect non-humans, it is called reverse zoonosis or anthroponosis. Major modern diseases such as Ebola 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. Human infection with animal influenza viruses is rare, as they do not transmit easily to or among humans. However, avian and swine influenza viruses in particular possess high zoonotic potential, and these occasionally recombine with human strains of the flu and can cause pandemics such as the 2009 swine flu. Zoonoses can be caused by a range of disease pathogens such as emergent viruses, bacteria, fungi and parasites; of 1,415 pathogens known t ...

Genetic Predisposition
Genetic predisposition refers to a genetic characteristic which influences the possible phenotypic development of an individual organism within a species or population under the influence of environmental conditions. The term genetic susceptibility is often used synonymously with genetic predisposition and is further defined as the inherited risk for specific conditions, based on genetic variants. While environmental factors can influence disease onset, genetic predisposition plays a role in inherited risk of conditions, such as various cancers. At the molecular level, genetic predisposition often involves specific gene mutation, regulatory pathways, or epigenetic modifications that alter cellular processes, increasing disease risk. How to predict genetic predisposition There are several approaches commonly used in the field of genetics to predict a genetic predisposition toward a disease. * Genome-Wide Association Studies (GWAS): studies that identify genetic variants link ...

Staffordshire Bull Terrier
The Staffordshire Bull Terrier, also called the Staffy or Stafford, is a purebred dog of small to medium size in the terrier group that originated in the northern parts of Birmingham and in the Black Country of Staffordshire, for which it is named. They descended from 19th-century bull terriers that were developed by crossing bulldogs with various terriers to create a generic type of dog generally known as bull and terriers. Staffords share the same ancestry with the modern Bull Terrier, although the two breeds developed along independent lines, and do not resemble each other. Modern Staffords more closely resemble the old type of bull terrier, and were first recognised as a purebred dog breed by The Kennel Club of Great Britain in 1935. Within the broad sweep of dog history, the story behind the modern Stafford is rather brief and somewhat confusing because of the multiple aliases attached to these dogs in centuries past, such as the "Patched Fighting Terrier", "Staffo ...

French Bulldog
The French Bulldog () is a French breed of companion dog or toy dog. It appeared in Paris in the mid-nineteenth century, apparently the result of cross-breeding of Toy Bulldogs imported from England and local Parisian ratters."Le bouledogue Français, Ses origines" 'Official breed club created in 1898 (fr)' It is commonly kept as a pet and is among the most frequently registered dogs in a number of countries including Australia, the United Kingdom, and the United States. The breed is susceptible to various health problems as a consequence of being bred for a distinctive appearance, sporting a |
Bulldog
The Bulldog is a British breed of dog of mastiff type. It may also be known as the English Bulldog or British Bulldog. It is a stocky, muscular dog of medium size, with a large head, thick folds of skin around the face and shoulders and a relatively flat face with a protruding lower jaw. Selective breeding for appearance has led to increased susceptibility to health problems including brachycephaly, hip dysplasia, heat sensitivity and skin infections. The dogs may not be bred in Norway or the Netherlands, because of concerns about their quality of life. The modern Bulldog was bred as a companion dog from the Old English Bulldog, a now-extinct breed used for bull-baiting until that was outlawed under the Cruelty to Animals Act of 1835. The Bulldog Club (in England) was formed in 1878, and the Bulldog Club of America was formed in 1890. While often used as a symbol of ferocity and courage, the modern Bulldog is generally a friendly, amiable dog. It is commonly kept as a pe ...

List Of Chemotherapeutic Agents
This is a list of chemotherapeutic agents, also known as cytotoxic agents or cytostatic drugs, that are known to be of use in chemotherapy for cancer. This list is organized by type of agent, although the subsections are not necessarily definitive and are subject to revision. Each drug is listed once (at present), though it might fall in more than one subsection. A full alphabetical listing is included after the categorical listing. The agents in this list are often combined into chemotherapy agent for polychemotherapy (combination chemotherapy). For example, the CHOP regimen consists of cyclophosphamide, doxorubicin, vincristine and prednisone. Besides chemotherapy, medical oncology (pharmacotherapy for cancer) includes several noncytotoxic classes of therapy, such as hormonal therapy and targeted therapy (biologic therapy). Those agents are described in the relevant articles. Alkylating agents * Altretamine * Bendamustine * Busulfan * Carboquone * Carmustine * Chlor ...

Leishmaniasis
Leishmaniasis is a wide array of clinical manifestations caused by protozoal parasites of the Trypanosomatida genus ''Leishmania''. It is generally spread through the bite of Phlebotominae, phlebotomine Sandfly, sandflies, ''Phlebotomus'' and ''Lutzomyia'', and occurs most frequently in the tropics and sub-tropics of Africa, Asia, the Americas, and southern Europe. The disease can present in three main ways: Cutaneous leishmaniasis, cutaneous, mucocutaneous leishmaniasis, mucocutaneous, or visceral leishmaniasis, visceral. The cutaneous form presents with skin ulcers, while the mucocutaneous form presents with ulcers of the skin, mouth, and nose. The visceral form starts with skin ulcers and later presents with fever, low red blood cell count, and enlarged spleen and liver. Infections in humans are caused by more than 20 species of ''Leishmania''. Risk factors include poverty, malnutrition, deforestation, and urbanization. All three types can be diagnosed by seeing the paras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cushing's Syndrome
Cushing's syndrome is a collection of signs and symptoms due to prolonged exposure to glucocorticoids such as cortisol. Signs and symptoms may include high blood pressure, abdominal obesity but with thin arms and legs, reddish stretch marks, a round red face due to facial plethora, a fat lump between the shoulders, weak muscles, weak bones, acne, and fragile skin that heals poorly. Women may have more hair and irregular menstruation or loss of menses, with the exact mechanisms of why still unknown. Occasionally there may be changes in mood, headaches, and a chronic feeling of tiredness. Cushing's syndrome is caused by either excessive cortisol-like medication, such as prednisone, or a tumor that either produces or results in the production of excessive cortisol by the adrenal glands. Cases due to a pituitary adenoma are known as Cushing's disease, which is the second most common cause of Cushing's syndrome after medication. A number of other tumors, often referred to ...

Neoplasm
A neoplasm () is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia. The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger is removed. This abnormal growth usually forms a mass, which may be called a tumour or tumor.'' ICD-10 classifies neoplasms into four main groups: benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behavior. Malignant neoplasms are also simply known as cancers and are the focus of oncology. Prior to the abnormal growth of tissue, such as neoplasia, cells often undergo an abnormal pattern of growth, such as metaplasia or dysplasia. However, metaplasia or dysplasia does not always progress to neoplasia and can occur in other conditions as well. The word neoplasm is from Ancient Greek 'new' and 'formation, creation'.
