Wildlife Disease
Disease is described as a decrease in performance of normal functions of an individual caused by many factors, which is not limited to infectious agents. Furthermore, wildlife disease is a disease when one of the hosts includes a wildlife species. In many cases, wildlife hosts can act as a reservoir of diseases that spillover into domestic animals, people and other species. Wildlife diseases spread through both direct contact between two individual animals or indirectly through the environment. Additionally, human industry has created the possibility for cross-species transmission through the wildlife trade. Furthermore, there are many relationships that must be considered when discussing wildlife disease, which are represented through the Epidemiological Triad Model. This model describes the relationship between a pathogen, host and the environment. There are many routes to infection of a susceptible host by a pathogen, but when the host becomes infected that host now has the potenti ...

Cross-species Transmission
Cross-species transmission (CST), also called interspecies transmission, host jump, or spillover, is the transmission of an infectious pathogen, such as a virus, between hosts belonging to different species. Once introduced into an individual of a new host species, the pathogen may cause disease for the new host and/or acquire the ability to infect other individuals of the same species, allowing it to spread through the new host population. The phenomenon is most commonly studied in virology, but cross-species transmission may also occur with bacterial pathogens or other types of microorganisms. Steps involved in the transfer of pathogens to new hosts include contact between the pathogen and the host; the successful infection of an initial individual host, which may lead to amplification and an outbreak; and the adaptation of the pathogen, within either the original or new host, which may render it capable of spreading efficiently between individuals in populations of the new h ...

Bovine Tuberculosis
Bovines (subfamily Bovinae) comprise a diverse group of 10 genera of medium to large-sized ungulates, including cattle, bison, African buffalo, water buffalos, and the four-horned and spiral-horned antelopes. The members of this group are classified into loose tribes rather than formal subgroups, as the evolutionary relationships within the groups are still uncertain. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur. In many countries, bovid milk and meat is used as food by humans. Cattle are kept as livestock almost everywhere except in parts of India and Nepal, where they are considered sacred by most Hindus. Bovids are used as draft animals and as riding animals. Small breeds of domestic bovid, such as the Miniature Zebu, are kept as pets. Bovid leather is durable and flexible and is used to produce a wide range of goods including clothing and bags. Systematics and class ...

Animal And Plant Health Inspection Service
The Animal and Plant Health Inspection Service (APHIS) is an agency of the United States Department of Agriculture (USDA) based in Riverdale Park, Maryland, Riverdale, Maryland responsible for protecting animal health, animal welfare, and plant health. APHIS is the lead agency for collaboration with other agencies to protect U.S. agriculture from invasive pests and diseases. APHIS's Plant Protection and Quarantine, PPQ is the National Plant Protection Organization for the U.S., and the agency's head of veterinary services/veterinary Deputy Administrator is the Chief veterinary officer, Chief Veterinary Officer of the United States. History APHIS was created in 1972 by Secretary's Memorandum No. 1769. The origins of the agency predate creation of the USDA, to 1854 when the Office of Entomologist, Agricultural Section, United States Patent and Trademark Office, U.S. Patent Office was created. It was the first of three agencies that eventually were merged to form APHIS. In 1881, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oral Rabies Vaccine
The rabies vaccine is a vaccine used to prevent rabies. There are several rabies vaccines available that are both safe and effective. Vaccinations must be administered prior to rabies virus exposure or within the latent period after exposure to prevent the disease. Transmission of rabies virus to humans typically occurs through a bite or scratch from an infectious animal, but exposure can occur through indirect contact with the saliva from an infectious individual. Doses are usually given by injection into the skin or muscle. After exposure, the vaccination is typically used along with rabies immunoglobulin. It is recommended that those who are at high risk of exposure be vaccinated before potential exposure. Rabies vaccines are effective in humans and other animals, and vaccinating dogs is very effective in preventing the spread of rabies to humans. A long-lasting immunity to the virus develops after a full course of treatment. Rabies vaccines may be used safely by all age g ...

Animal Vaccination
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wild Animal Suffering
Wild animal suffering is suffering experienced by non-human animals living in the wild, outside of direct human control, due to natural processes. Its sources include disease, injury, parasitism, starvation, malnutrition, dehydration, weather conditions, natural disasters, killings by other animals, and psychological stress. An extensive amount of natural suffering has been described as an unavoidable consequence of Darwinian evolution, as well as the pervasiveness of reproductive strategies, which favor producing large numbers of offspring, with a low amount of parental care and of which only a small number survive to adulthood, the rest dying in painful ways, has led some to argue that suffering dominates happiness in nature. Some estimates suggest that the total population of wild animals, excluding nematodes but including arthropods, may be vastly greater than the number of animals killed by humans each year. This figure is estimated to be between 10¹⁸ and 10²¹ indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabies Vaccine In Bait
Rabies is a viral disease that causes encephalitis in humans and other mammals. It was historically referred to as hydrophobia ("fear of water") because its victims panic when offered liquids to drink. Early symptoms can include fever and abnormal sensations at the site of exposure. These symptoms are followed by one or more of the following symptoms: nausea, vomiting, violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness. Once symptoms appear, the result is virtually always death. The time period between contracting the disease and the start of symptoms is usually one to three months but can vary from less than one week to more than one year. The time depends on the distance the virus must travel along peripheral nerves to reach the central nervous system. Rabies is caused by lyssaviruses, including the rabies virus and Australian bat lyssavirus. It is spread when an infected animal bites or scr ...

Wildlife Rehabilitation
Wildlife rehabilitation is the process of caring for injured, sick, orphaned, or displaced wild animals with the goal of releasing them back into their natural habitat. It involves medical treatment, temporary housing, and specialized care for a variety of species, from birds and mammals to reptiles and amphibians. Wildlife rehabilitation combines veterinary science, wildlife conservation, and animal welfare to ensure that animals have the best chance for recovery and survival after facing challenges such as injury, disease, or human interference. In addition to caring for animals, wildlife rehabilitators often work to educate the public about conservation, habitat protection, and how to coexist with wildlife. They play an essential role in addressing the effects of human activities on wild animal populations, including habitat destruction, pollution, and vehicle collisions. Process Wildlife rehabilitation requires specialized knowledge and training in wildlife biology, veterina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intrinsic Value (animal Ethics)
The intrinsic value of a human or any other sentient animal comes from within itself. It is the value it places on its own existence. Intrinsic value exists wherever there are beings that value themselves. Intrinsic value is considered self-ascribed, all animals have it, unlike instrumental or extrinsic values. Instrumental value is the value that others confer on an animal (or on any other entity) because of its value as a resource (e.g. as property, labour, food, fibre, "ecosystem services") or as a source of emotional, recreational, aesthetic or spiritual gratification. Intrinsic values are conferred from within an animal, and are therefore not directly measurable by economists, while extrinsic values are conferred from outside and can, in principle, be measured econometrically. The phrase "intrinsic value" (often used synonymously with ''inherent value'') has been adopted by animal rights advocates. The Dutch ''Animal Health and Welfare Act'' referred to intrinsic value in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Rights
Animal rights is the philosophy according to which many or all Animal consciousness, sentient animals have Moral patienthood, moral worth independent of their Utilitarianism, utility to humans, and that their most basic interests—such as avoiding suffering—should be afforded the same consideration as similar interests of human beings. The argument from marginal cases is often used to reach this conclusion. This argument holds that if marginal human beings such as infants, senile people, and the Cognition, cognitively disabled are granted moral status and negative rights, then nonhuman animals must be granted the same moral consideration, since animals do not lack any known morally relevant characteristic that marginal-case humans have. Broadly speaking, and particularly in popular discourse, the term "animal rights" is often used synonymously with "animal protection" or "animal liberation". More narrowly, "animal rights" refers to the idea that many animals have fundamen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity
Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distributed evenly on Earth. It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Since Abiogenesis, life began on Earth, six major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion. In this period, the majority of Multicellular organism, multicellular Phylum, phyla first appeared. The next 400 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
