2.3.3. Gene deleted vaccines The knowledge of specific virulence factor(s) of a pathogen and the availability of recombinant DNA technology has facilitated the creation of specific gene-deleted pathogens for use as live vaccines. The approach of creating and testing defined gene deletions ultimately aids in reducing the pathogenicity/virulence of the organism without affecting the immunogenicity. Such gene-deleted organisms can be used as vaccines as they retain the immunogenic features of the wild-type

There are two variations, viruses with envelopes and viruses with RNA genomes, though some have both of these features.

mutation. Researchers have discovered that the vector system for coagulation therapy is adeno-associated virus (AAV) based strategies as they have shown to be leading the way for coagulation therapy. AAV are infectious agents that belong to the parvovirus family and result in asymptomatic infection in humans. To date, about 31 Haemophilia B patients have been treated in 5 AAV clinical trials. A clinical study to deliver factor VIII has only just one patient enrolled. As AVV viral vectors have small

The California Biomedical Research Association claims that if vaccines were not tested on animals, millions of animals would have died from rabies, distemper, feline leukemia, infectious hepatitis virus, tetanus, anthrax, and canine parvovirus (CBRA). The treatments needed to cure people have been proven to help keep animals healthy from infection and disease, which in this case is a win win situation. The article also mentions that, “treatments for animals developed using animal testing

I. Introduction There is no other breed like the Pug. Not only does he look distinctive, but he has a character like no other. His furrowed brow may make him appear perpetually worried, but beneath the wrinkles lies a happy-go-lucky dog with a clown-like personality. Ask Pug owners to describe their dogs, and the same words crop up time and again: ‘loving’, ‘intelligent’, ‘alert’, and ‘inquisitive. However, one word appears more than any other – ‘fun’! This is a dog that will keep you amused for

These include genetic defects, hormonal factors, medications, some infections, exposure to ultraviolet B light, and chemical exposure. Some of the infections that are suspected triggers are the Epstein-Barr virus, cytomegalovirus, parvovirus, and hepatitis C. Some known chemical exposures include trichloroethylene found in well water and silica dust. The most common symptoms are fatigue, rashes, or joint pain. Other symptoms that might develop are skin problems, sensitivity to light

If vaccines were not tested on animals, millions of animals would have died from rabies, distemper, feline leukemia, infectious hepatitis virus, tetanus, anthrax, and canine parvovirus. The Animal Welfare Act protects certain animals from inhumane treatment and neglect. Congress passed the law in 1966, after legislators learned the story of a pet Dalmatian named Pepper who was taken from its family's backyard in 1965 and sold

Products should be tested on animals before released to humans to prevent complications, disease, or death is a widely accepted opinion regarding this topic. As previously mentioned, animal testing has resulted in many medical breakthroughs and cures that would have otherwise not happened if it weren’t for testing and researching on animals. Animal testing has especially helped us in understanding certain cancers and diseases such as, “breast cancer, brain injury, childhood leukemia, cystic fibrosis

occur with animal breeders, such as heart issues and epilepsy. There are usually too many multiple animals that the employees are taking care of, so they usually don’t catch a lot of illnesses that puppies can contract such as, canine distemper, parvovirus, and severe gastrointestinal disorders that they are prone to while at the pet store. The owner would then have to make the terrible decision of taking it back to the pet store or spend hundreds and hundreds of dollars on a treatment that might

Discussion: Polyarteritis Nodosa is an autoimmune disease caused by immune deposition in the wall of small to medium sized muscular arteries.13 This process promotes infiltration with polymorphic leukocytes and liberation of necrotizing enzymes, leading to thrombosis, tissue ischemia, fibrosis, and ultimately tissue scarring. PAN may affect virtually every organ system and has a wide constellation of clinical manifestations (Table 1).14 Establishing the diagnosis of PAN is very difficult as there
