I am currently working on my Extended Project Qualification, and thought it would be interesting to let my blog followers know about what my subject area is. I am writing around both the science and ethics of BSE in cattle and it’s transmissible properties to humans which go on to progress to the human prion causing disease CJD. After much research into BSE I have found a variety of theories that were proposed around the time, one in particular caught my eye with determination and will power as intriguing and admirable characteristics. This is a theory proposed by the organic farmer Mark Purdey, whom believed that one of the causes of BSE in cattle was organophosphates which contained Phosmet. He knew that this OP was administered along the spine of the cow, and was designed to penetrate the spinal cavity of the cow producing a poisonous environment against the marble fly.
Unfortunately this theory underwent such dismissal by the scientific community and after reading ‘Animal Farm’ by Nigel/Mark Purdey I have realised the amount of effort and research this man put into such a concerning matter. I urge any one who is interested in Veterinary Medicine or in fact Human Medicine for the fact CJD is linked within the BSE enquiry to read this book and to read around topical issues such as BSE as there is constantly important breakthroughs that intrigue and enthuse me.The theory was that this OP was causing biochemical changes to some of the protein structures within the nervous and spinal tissue of cattle, in particular it was the Prion protein that is discovered to have been the cause for the neuro-degenerative property of BSE. Purdey proposed OP as causing a misfolding of the prion protein causing it to have infectious properties.
I have been call all day with the equine vet from Agnew Veterinary Clinic, it was absolutely fantastic and really has widened my knowledge around the equine area. I saw various call outs some of these included;
- My first call out was unfortunately to two euthanasia’s on two old horses, although a sad situation I appreciated the fact that this is something vital that I needed to see and found it very interesting. The vet administered a local sedative before injecting with barbiturate overdose.
- The second call out was a horse that required it’s tetanus and influenza vaccination, the tetanus vaccination after a course of 3 injections over the period of around 200 days can be given every other year where as the influenza vaccine must be administered every year. Other vaccines that can be recommended is herpes which is common among pregnant mares.
- The next call out was to a livery/breeding stables which was having some of its foals wormed and micro chipped and pass ported, it is absolutely vital that each horse has its own passport for identification purposes. Restraining the foals proved a difficult and strenuous task but once micro chipped felt fully rewarding.
- We then made our way to a horse that had swelling on its cannon bone, although not showing considerable lameness the vet administered some antibiotics as the owner wanted peace of mind before going on holiday.
- The final call was to a horse with a rather serious open wound on the inner elbow; the vet assessed the wound and found it went right down to the bone. To diagnose whether or not surgery would be necessary the vet pressed a needle into the other side of the elbow to look if the saline solution flowed through the wound as this would mean that infection will have spread to the cartilage and bone. Luckily this was not the case and this could be treated by flushing the wound and a lot of bandaging.
- Gave my first injection today of Synulox (which is an anti-bacterial infection and aims to prevent further infections) to a dog that had just been x-rayed and was diagnosed with narrow airway disease.
- Dog came in with an Alopecia which has caused hair loss on both the dog’s nose and the dog’s tail (commonly known as rat tail) diagnosed with Alopecia areata. The typical course of treatment for allergies consists of antihistamines and the elimination of the allergens
- External parasites will make the dog scratch and lick the irritated skin and the hair loss is self-inflicted. However, if the dog is allergic to the parasite bites, he may lose hair in the affected areas
- A ringworm infection, which is caused by fungi and will cause round shaped bald patches
- Thyroid gland function issues and the production of thyroid hormones in excess. The hair -becomes easy to pull out and the dog will often chew on his coat, leading to bald patches
- Allergic reactions to various inhalants or topical creams and shampoos
- Stress, which can make the dog inflict hair loss
- Cushing’s disease, which is an abnormal function of the adrenal glands
- Treatment with certain drugs such as chemotherapy.
- Shia Tzu came in struggling to breathe and constantly wrenching, the vet then carried out an xray. This confirmed his thoughts that the dog had narrow airway disease. Its treatment as yet is under question.
- Dog brought in that had had all of its claws removed in a previous surgery, two of the areas where the claws had been removed has begun to grow back with keratin. The vet suggested removing them surgically and explained that the dog had recovered successfully and this was to be expected.
