mad cow disease
The term ‘Mad Cow’ disease is almost a household name, but only a few people actually know what it means. Bovine Spongiform Encephalopathy, more commonly known as Mad Cow disease, infects cows and turns their brains into what resembles a sponge.
BSE is the cause for over 30 million deaths in Europe alone. Out of the 30 million, 12 million cases have been reported in the United Kingdom.
Creutzfeld-Jacob (CZ or CJD) is the human equivalent of BSE. Identified first in the 1920’s, it causes the gradual decline of mental ability.
All of the diseases mentioned are prion based diseases. Once inside the body, the prions which are self replicating protiens, grow and cause the brain to become spongy. Prions have been reported to be found in contaminated soil and water.
Because HIV was previously believed to be harmless to babies nursing on breastmilk, Prions at first were no threat to milk. When HIV was proven to be able to transmit itself through breast milk people started to worry. One death was blamed on CJD. A woman dying with CJD had shown signs of the disease in her colostrum (the type of breast milk made in the first few days after delivering a baby).
However In 1995, the British Spongiform Encepalopathy Advisory Committee dismissed claims that BSE can be passed in milk. The Committee published its reports in The Veterinary Record in June 1995. A team of British scientists form all over the UK worked on this. The team fed milk from cows dying from BSE to mice for 40 days, then observed the mice for about two years. To take their experiment to another level, they also injected milk from a BSE infected cow straight into the brains and the skin of mice. They thought that by doing this they would get positive results for infections. These mice were also watched by the scientists for two years.
The results turned out to be negative for both of the experiments. Dr. Haresh Narang, a critic of the British study of BSE, called the study ‘worthless’. He believes that the milk should have been fed to Mink. Mink can consume as much milk a an average human baby can. The Scientists argued by saying that the amount of milk given to the mice was equivalent to a human drinking a pint of milk a day from an infected cow for almost seven years.
To prove that milk did not contain any BSE, The same mice tested before once again subjected to testing. This time the mice were injected with other parts of organs from infected cows, like the brain and spinal fluid. The mice then developed the disease.

Errherrh Human Disease IINTRODUCTION Human Disease, in medicine, any harmful change that interferes with the normal appearance, structure, or function of the body or any of its parts. Since time immemorial, disease has played a role in the history of societies. It has affected-and been affected by-economic conditions, wars, and natural disasters. Indeed, the impact of disease can be far greater than better-known calamities. An epidemic of influenza that swept the globe in 1918 killed between 20 mill
Diseasedisease The Mysteries Surrounding Creutzfeldt-Jakob Disease Creutzfeldt-Jakob Disease is a killer. What we know is that it wastes no time. Creutzfeldt-Jakob Disease will kill a person within one year of contraction. It is yet unknown how Creutzfeldt-Jakob Disease chooses its victims, but it does seem to have accomplices, known as the spongiformencephalopathies, in the rest of the animal kingdom. It is possible that it may be known what means Creutzfeldt-Jakob Disease uses in order to annihilate
Mad Cow Mad Cow MAD COW DISEASE INTRODUCTION Mad Cow disease has been heavily spoken about on the international news. Our hopes are that the disease will not spread into the United States, even though several people have died from the disease. PURPOSE, SCOPE AND LIMITATIONS Our initial purpose of researching this topic has been inspired by the growing concern for the outbreak of Mad Cow Disease and its various forms. We believe that it is imperative that we take our research and implement it to others
Creutzfeldt-Jakob disease (CJD)—a fatal neurodegCJD Creutzfeldt-Jakob disease (CJD)—a fatal neurodegenerative illness, is one form of transmissiblespongiformencephalopathies (TSE) affecting humans. The suspected causal agent of these diseases is the prion—a proteinaceous infectious particle. Designated as PrPSC, this infectious protein is unique in that it does not contain nucleic acid, which is different from a virus, yet has the capability of replication and being transmitted to other hosts. This capability of transmission poses a maj
