Feline Vaccination
Feline vaccination is animal vaccination applied to cats. Vaccination plays a vital role in protecting cats from infectious diseases, some of which are potentially fatal. They can be exposed to these diseases from their environment, other pets, or even humans. Principles guiding vaccination recommendations The practice of recommending and giving vaccines on a fixed schedule with annual boosters has been widely discarded. Current recommendations are based on the philosophy of vaccinating each cat no more frequently than necessary. These recommendations take into account considerations for the efficacy and duration of immunity (DOI) of available vaccines; environmental risks and likelihood of exposure; the specific needs and risks associated with age and overall health status of different cats and cat populations; and socioeconomic limitations. Recommendation vary for: * Shelters * Owned pets (and based on "inside only", "in and out", or "out only") * Breeders * Boarding facilitie ...

Animal Vaccination
Animal vaccination is the immunisation of a domestic, livestock or wild animal. The practice is connected to veterinary medicine. The first animal vaccine invented was for chicken cholera in 1879 by Louis Pasteur. The production of such vaccines encounter issues in relation to the economic difficulties of individuals, the government and companies. Regulation of animal vaccinations is less compared to the regulations of human vaccinations. Vaccines are categorised into conventional and next generation vaccines. Animal vaccines have been found to be the most cost effective and sustainable methods of controlling infectious veterinary diseases. In 2017, the veterinary vaccine industry was valued at US$7 billion and it is predicted to reach US$9 billion in 2024. History Animals have been both the receiver and the source of vaccines. Through laboratory testing, the first animal vaccine created was for chicken cholera in 1879 by Louis Pasteur. Pasteur also invented an anthrax vaccine ...

Feline Leukemia Virus
Feline leukemia virus (FeLV) is a retrovirus that infects cats. FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved. If not defeated by the animal's immune system, the virus weakens the cat's immune system, which can lead to diseases which can be lethal. Because FeLV is cat-to-cat contagious, FeLV+ cats should only live with other FeLV+ cats. FeLV is categorized into four subgroups, A, B, C and T. An infected cat has a combination of FeLV-A and one or more of the other subgroups. Symptoms, prognosis and treatment are all affected by subgroup. FeLV+ cats often have a shorter lifespan, but can still live "normal", healthy lives. Signs and symptoms The signs and symptoms of infection with feline leukemia virus are quite varied and include loss of appetite, poor coat condition, anisocoria (uneven pupils), infections of the skin, bladder, and respiratory tract, oral disease, seizures, lymphadenopathy (swollen lymph nodes), skin l ...

Vaccine-associated Sarcoma
A vaccine-associated sarcoma (VAS) or feline injection-site sarcoma (FISS) is a type of malignancy, malignant tumor found in cats (and often, dogs and ferrets) which has been linked to certain vaccines. VAS has become a concern for veterinarians and cat owners alike and has resulted in changes in recommended vaccine protocols. These sarcomas have been most commonly associated with rabies and feline leukemia virus vaccines, but other vaccines and injected medications have also been implicated. History VAS was first recognized at the University of Pennsylvania School of Veterinary Medicine in 1991. An association between highly aggressive fibrosarcomas and typical vaccine location (between the shoulder blades) was made. Two possible factors for the increase of VAS at this time were the introduction in 1985 of vaccines for rabies and feline leukemia virus (FeLV) that contained aluminum adjuvant, and a law in 1987 requiring rabies vaccination in cats in Pennsylvania. In 1993, a Caus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adverse Events
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An adverse event can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. AEs in patients participating in clinical trials must be reported to the study sponsor and if required could be reported to the local ethics committee. Adverse events categorized as "serious" (results in death, illness requiring hospitalization, events deemed life-threatening, results in persistent or significant incapacity, a congenital anomaly, birth defect or medically important condition) must be reported to the regulatory authorities immediately, whereas non-serious adverse events are ...

Inactivated Vaccine
An inactivated vaccine (or killed vaccine) is a vaccine consisting of virus particles, bacteria, or other pathogens that have been grown in culture and then killed to destroy disease-producing capacity. In contrast, live vaccines use pathogens that are still alive (but are almost always attenuated, that is, weakened). Pathogens for inactivated vaccines are grown under controlled conditions and are killed as a means to reduce infectivity and thus prevent infection from the vaccine. Inactivated vaccines were first developed in the late 1800s and early 1900s for cholera, plague, and typhoid. Today, inactivated vaccines exist for many pathogens, including influenza, polio (IPV), rabies, hepatitis A and pertussis. Because inactivated pathogens tend to produce a weaker response by the immune system than live pathogens, immunologic adjuvants and multiple "booster" injections may be required in some vaccines to provide an effective immune response against the pathogen. Attenuated vacci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adjuvant
In pharmacology, an adjuvant is a drug or other substance, or a combination of substances, that is used to increase the efficacy or potency of certain drugs. Specifically, the term can refer to: * Adjuvant therapy in cancer management * Analgesic adjuvant in pain management * Immunologic adjuvant In immunology, an adjuvant is a substance that increases or modulates the immune response to a vaccine. The word "adjuvant" comes from the Latin word ''adiuvare'', meaning to help or aid. "An immunologic adjuvant is defined as any substance that ... in vaccines This is a specialized usage of a word (derived from the Latin verb "adjuvare", ''to help''), which also has a more general meaning as someone or something assisting in any operation or effect. {{sia Adjuvants ...

Live Vaccine
An attenuated vaccine (or a live attenuated vaccine, LAV) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. These vaccines contrast to those produced by "killing" the virus (inactivated vaccine). Attenuated vaccines stimulate a strong and effective immune response that is long-lasting. In comparison to inactivated vaccines, attenuated vaccines produce a stronger and more durable immune response with a quick immunity onset. Attenuated vaccines function by encouraging the body to create antibodies and memory immune cells in response to the specific pathogen which the vaccine protects against. Common examples of live attenuated vaccines are measles, mumps, rubella, yellow fever, and some influenza vaccines. Development Attenuated viruses Viruses may be attenuated using the principles of evolution via serial passage of the virus thro ...

Bordetella Bronchiseptica
''Bordetella bronchiseptica'' is a small, gram-negative, rod-shaped bacterium of the genus ''Bordetella''. It can cause infectious bronchitis in dogs and other animals, but rarely infects humans. Closely related to '' B. pertussis''—the obligate human pathogen that causes pertussis (whooping cough); ''B. bronchiseptica'' can persist in the environment for extended periods. Pathogenesis Humans are not natural carriers of ''B. bronchiseptica'', which typically infects the respiratory tracts of smaller mammals (cats, dogs, rabbits, etc.). People are more likely to be infected by ''B. pertussis'' or '' B. parapertussis''. Unlike ''B. pertussis'', ''B. bronchiseptica'' is generally resistant to macrolide antibiotics. It is also generally resistant to cephalosporins. Some human cases have been successfully treated with trimethoprim/sulfamethoxazole and fluoroquinolones. ''B. bronchiseptica'' does not express pertussis toxin, which is one of the characteristic virulence factors of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlamydophila Felis
''Chlamydia felis'' (formerly ''Chlamydophila felis'' and before that ''Chlamydia psittaci'' var. ''felis'') is a Gram-negative, obligate intracellular bacterial pathogen that infects cats. It is endemic among domestic cats worldwide, primarily causing inflammation of feline conjunctiva, rhinitis and respiratory problems. ''C. felis'' can be recovered from the stomach and reproductive tract. Zoonotic infection of humans with ''C. felis'' has been reported. Strains FP Pring and FP Cello have an extrachromosomal plasmid, whereas the FP Baker strain does not. FP Cello produces lethal disease in mice, whereas the FP Baker does not. An attenuated FP Baker strain, and an attenuated 905 strain, are used as live vaccines for cats. Taxonomy and Phylogeny The genus ''Chlamydia'' contains the species '' C. trachomatis, C. psittaci, C. abortus, C. felis, C. muridarum, C. suis, C. caviae, C. pecorum,'' and '' C. pneumoniae.'' However, there is some dispute that some of these species, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feline Immunodeficiency Virus
Feline immunodeficiency virus (FIV) is a '' Lentivirus'' that affects cats worldwide, with 2.5% to 4.4% of felines being infected. FIV was first isolated in 1986, by Niels C Pedersen and Janet K. Yamamoto at the UC Davis School of Veterinary Medicine in a colony of cats that had a high prevalence of opportunistic infections and degenerative conditions and was originally called Feline T-lymphotropic virus. It has since been identified in domestic cats. It has been suggested FIV originated in Africa and has since spread to feline species worldwide. Effects FIV compromises the immune system of cats by infecting many cell types, including CD4+ and CD8+ T lymphocytes, B lymphocytes, and macrophages. FIV can be tolerated well by cats, but can eventually lead to debilitation of the immune system in its feline hosts by the infection and exhaustion of T-helper (CD4+) cells. FIV and HIV are both lentiviruses. However, humans cannot be infected by FIV, nor can cats be infected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabies
Rabies is a viral disease that causes encephalitis in humans and other mammals. Early symptoms can include fever and tingling 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, regardless of treatment. 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 scratches a human or other animals. Saliva from an infected animal can also transmit rabies if the saliva come ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cats
The cat (''Felis catus'') is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is commonly referred to as the domestic cat or house cat to distinguish it from the wild members of the family. Cats are commonly kept as house pets but can also be farm cats or feral cats; the feral cat ranges freely and avoids human contact. Domestic cats are valued by humans for companionship and their ability to kill rodents. About 60 cat breeds are recognized by various cat registries. The cat is similar in anatomy to the other felid species: they have a strong flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey. Their night vision and sense of smell are well developed. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling, and grunting as well as cat-specific body language. Although the cat is a social species, they are a solitary hunter. As a pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
