Animal Diseases, Pathology and Immunology Research Project Lymphosarcoma in Horses
Horses typically do not get cancer. When they do it is generally Lymphosarcoma and, unfortunately, it is usually lethal. Cancer generally strikes anywhere from 4-10 years of age. Cancer is the uncontrolled growth of cells that develop in to masses, or tumors. These tumors can hide anywhere on such a large animal. There are four typical types of lymphosarcoma in the horse. They are generalized (multi-centric), intestinal, mediastinal and cutaneous.
The generalized form is most common. Tumors may be found throughout the entire lymph node system including internal and multiple peripheral nodes. The most common locations include between the jaw,

Looking for why it’s the best form if your horse is going ot get cancer. Is it the most treatable with the best outcome? You just remove the lumps?
DIAGNOSIS: Unfortunately in a horse, the best way to find this lymphosarcoma is by ruling out forms of cancer. CBC and serum chemistries are generally not helpful nor definitive. Cancer should be suspected if there is anemia, hyperfibrinogenaemia, hyperproteinaemia, and hypoalbuminaemia without any other clear definition of any infectious disease. Biopsies can be performed, however this can sometimes introduce tumor cells into the blood stream which can spread the cancer. Fine needle aspirates may be done on surface or even cutaneous masses.
Q Fever
Q Fever, or Coxiella burnetti is most frequently found in ruminates such as cattle, sheep and goats. Unfortunately it has also been found in wildlife and pets. Sheep are the most frequently infected, followed by goats and lastly cattle. Ticks carry the disease, but are of minor importance in the transmission of the disease to people and animals.
Coxiella burnetti is shed in the feces, milk and urine of the infected animals. The highest incidence of infections comes from the vaginal secretions and uterine fluids of infected ewes and does so during the birthing process. It is shed for days or even weeks. There are very few symptoms of Q Fever, abortion being the main commonality.
Since each horse is different they can show different types of symptoms. Some horses get many symptoms and others none. I’ve provided you a list that seems to be one of the most comprehensive I could find. This list is provided from an article by DVM Bentz Commissioner for the Kentucky Racing Commission.
The well being of the patient will be on the factors of the location of the tumor and where the sarcoma has spreads.
Some Soldiers took advantage of horses by not caring for their needs. These poor horses were not well-taken care which contributed to their contraction of diseases and illness. “The ignorance of unqualified inspectors led to the purchase of great numbers of sickly and worn-out horses for the army” (“warhorses”11). The Horses needed to be in perfect shape to fulfill missions. But many horses were put through so much that they would catch diseases by not being well-taken care off. “Even animals that were healthy when purchased were soon reduced to a pitiful condition by the low standards of care they received once in service” (“warhorses”11). The careless soldiers brought up death to their horses by not watching over them or their health. History today discusses how the horse camps were heavily overcrowded and the animals suffer by not being groomed and fed “horses suffered because their injury or illness offered the prospect of furlough to their rider” (Phillips174). This put the horses in a dangerous situation that resulted in their death. The dangerous conditions often put the soldiers in a difficult place. With the death of horses, it halted communication and transportation. Messages weren’t able to be sent quickly which brought problems to the war. Without transportation troops, could travel quickly because horses became unnumbered. While horses were dying off this resulted from a soldier spending more money buying horses. The war was already expensive and this was an unnecessary expense. More soldiers were dying because of the lack of protection because of exhausted

Cancer is defined as the disease caused by an uncontrollable division of abnormal cells in a part of the body. The particular cancer that I️ researched is Non-Hodgkin Lymphoma (NHL) which is a type of cancer that begins in the cells of the lymph system. (Lymphoma) The lymph system is a part of the immune system. Lymph tissue is found all throughout the body; therefore, Lymphoma can begin from almost any part of the body since the major sites of lymph tissue are the lymph nodes, spleen, bone marrow, thymus, digestive tract, and adenoids and tonsils. (What) “In most cases, it is not known what causes Non-Hodgkin Lymphoma.” (Risk) Some risk factors of NHL are beyond our control such as age and gender but usually they are acquired rather than inherited. (Risk) NHL begins in white blood cells called lymphocytes. (What) There are two main types of lymphocytes: B lymphocytes ( B cells) and T lymphocytes (T cells). B cells normally create antibodies to

The article Whooping Cough Mark Near, from the Fresno Bee, describes the conditions of this new occurring virus. According to the article, the
Cancers arising from the lymph nodes or other sites of lymphoid tissue are broadly termed lymphomas. This group of diseases is divided into Hodgkin’s disease and non-Hodgkin’s lymphoma. In both conditions, there is a replacement of normal lymphatic tissue by collections of abnormal lymphoma cells.
One specific type of cancer is called Angiosarcomas, or cancer of the endothelial cells. This is a rare, and very serious form of cancer. This type of cancer occurs in the head and neck region, and it usually appears in the scalp of the elderly. Occasionally
Of 37 cases, 9 cases occurred in major salivary glands, with eight occurrences in the parotid region - 1 PA, 1 Adenolymphoma & 6 Acinic cell adenocarcinoma (AcADCC) and one in submandibular region- 1 Polymorphous low grade adenocarcinoma (PLGA). Of 37 cases, 28 cases occurred in minor salivary glands, with palate being the most commonly affected site by both benign (63.63%) and malignant tumors (58%).
As in humans, cancer in canines is fairly common. There are various types of tumors that are commonly seen as cancerous tumors can develop from any type of tissue and any location. Having knowledge and awareness about the various types of Canine Tumors is the key to monitor your pet and possibly detect the abnormality at an earlier stage. Do remember that early stage detection without metastasis helps in increasing the chances of proper treatment and possibly cure.
A biopsy of the suspected cancer tissue is the only definitive diagnosis (Davis, 2016). There are several different ways a biopsy can be obtained such as through an endoscopy, needle biopsy, and surgical biopsy. Once the biopsy is obtained the tissue is examined under a microscope to determine whether the tumor is malignant or benign, type of cancer, and the tumor grade ("Module 6: Cancer," 2011). The tumor grade refers to how similar or different the cells resemble the normal tissue. If the tumor cells resemble the normal tissue it is referred to as well differentiated and tends to be slow growing and leads to good prognosis. However, if the tumor cells do not resemble or only slightly resemble the normal tissue it is referred to as poorly differentiated or undifferentiated. This is usually indicative of a fast growing and more aggressive cells that may ultimately lead to a poorer prognosis (“Module 6: Cancer,” 2011).
"Glanders is an infectious disease caused by the bacteria Burkholderia mallei." (Glanders) This disease mainly affects horses, but also affects donkeys and mules and can be contracted by other mammals such as goats, dogs, and cats. "Burkholderia mallei are transmitted to humans through contact with tissues or body fluids of infected animals." (Glanders) "The bacteria enter the body through cuts or abrasions in the skin and through mucosal surfaces such as the eyes and nose." (Glanders) "The bacteria can also be inhaled via infected aerosols or dust contaminated by infected animals." (Glanders) There have been no reported cases of glanders in the US since the 1940s. Reports of glanders have been in Africa, Asia, The Middle East,
Equine has an important role all over the world of veterinary sciences as well as civilians interesting, but internal parasites affect equine reduce their physical powers and beautiful appearance which is important for racing and showing. We focus in our review on epidemiology diagnosis and treatment of strongylosis as an important parasitic disease in equine. There are two strongyle families; firstly is the large strongyle which caused by stronglus vulgaris which is the most pathogenic and wide spread species in equine that may cause severe internal organs damage. Verminous Arthritis Embolism may cause death due to migration larvae. The second member is the Small strongyle which causes mild symptoms of diarrhea and weight loss.
Horses are a cool kind of animal to learn about. You may not know all of their appearance secrets. They may be found in many different places. They don’t hunt but other animals may hunt them!Horses make a big difference in our lives.
