Cattle Tick
The cattle tick Boophilus microplus is a significant ectoparasite of cattle and a vector for important diseases such as babesiosis
and anaplasmosis.
Classification
SPC List D disease
Susceptible species
B. microplus is primarily a parasite of cattle. However, heavy infestations can also occur on horses, sheep, deer and water
buffalo. Rarely, ticks have been reported on marsupials, goats, dogs, cats and pigs.
Where it occurs
The cattle tick is widely distributed in Central and South America, parts of the southern USA, Africa, Asia, and northern
Australia. The distribution of the cattle tick is largely determined by climatic factors. B. microplus requires high humidity and
ambient temperatures of at least 15-20o C for egg laying and hatching.
Clinical signs
Cattle tick infestation causes:
· damage to hides
· loss of production
· anaemia and death
· weakness leading to greater mortalities during droughts
Post-mortem findings
Animals may be in poor condition, anaemic. Infestations will be obvious by the presence of engorged ticks attached to the
animal's skin.
Differential diagnosis
Several species of ticks may be found on cattle and it is important to differentiate these from B. microplus. Other ticks include:
· Haemophysalis sp..
· Ixodes holocyclus
Specimens required for diagnosis
Ticks should be collected and forwarded to an entomologist for confirmation of the diagnosis. B. microplus has pale legs, short
mouth parts with transversely ridged palps, small eyes and lacks an anal groove.
Transmission
The life cycle involves free-living stages. After feeding on cattle, engorged female ticks drop to the ground and lay ...

...20,000 ticks are needed. This is a difficult
demand to keep up with and so instead of breeding the cattle ticks the traditional way the ticks are
genetically engineered as this is a faster easier method.
A specific antigen is needed to be found and isolated from samples which
are taken from the gut of a tick. The antigen needed was a protein which
triggers the immunity system. To isolate the particular protein it had to be
identified from about ten thousand proteins found in the gut. Once the
particular gene is isolated from the tick it is put into the bacterium which
then produces a synthetic antigen. Lastly, this synthetic antigen is inserted
into a stable vaccine.

This parasite is spread through the bite of sandflies. There are three different types of infections and they each show varying degrees of severity. The cutaneous form produces mild skin ulcers, mucocutaneous produces ulcers in the mouth and nose, and the visceral form of the disease starts with skin ulcers and then fever, low red blood cell count, and an enlarged spleen and liver. The parasite is detected by a microscope and visceral can also be found by doing blood tests. 12 million people are in infected in 98 different countries and 2 million new cases are found every year. The disease also kills around 20 to 50 thousand people a year.
The female mosquito bites an infected animal then carries their offspring which are called Microfilariae to your dog. (Administration, Animal and Veterinary)
Although most people don't realize it, one of the most weakening diseases of the world can often be found crawling around in the shrubs and tall grasses of a person’s backyard .It does not mean that only dirty yards have this disease but it is found in every Americans backyard. The disease is called Lyme disease. Now I will be elaborating on the disease.
If these problems could be eradicated it could save a lot of time and money for the farmers. The use of antibiotics and hormones before the livestock actually catches
Wear gloves and proper cloths if handling the infected animals to prevent the direct contact.
The topic of my case study is Lyme Disease. Lyme disease is a vector transmitted disease that is common in the United States and other areas of the world, United Kingdom, Sweden and a few other European countries. This disease is caused a spirochete from the deer tick or Ixodes scapularis. It is on the rise in the United States and in the European countries. In the United States, there were over 25,000 known cases in the Midwest with less cases that are known around the rest of the country. Lyme disease is also known as Borrelia burgdorferi and is transmitted via ticks that will attach themselves to a human host and bury
Scabies mites are distributed worldwide, affecting all races, ages and socioeconomic classes in all climates. Sarcoptes scabei, human itch, or mange mites, are in the arthropod class Arachnida, subclass Acari, family Sarcoptidae. These mites burrow under the skin, living in linear burrows. Other races of scabies may cause infestations in other mammals such as domestic cats, dogs, pigs, and horses. It should be noted that races of mites found on other animals could not establish infestations in humans. They may cause temporary itching due to dermatitis but they do not tunnel into the skin.
Common hosts include wild and domestic livestock for instance goats, cattle, horses and sheep (Mayoclinic.org, 2012). Unlike other pathogenic bacteria, which are host specific; only to be able to affect one specific species, Anthrax is able to infect livestock and humans, with soil having little to no effect until it is transferred to a host.
Fleas and ticks are annoying little pests that live in the fur of your pets. The hot, sunny months in Pensacola provide the perfect environment for these little parasites to feed on your pet’s blood. Fleas and ticks are extremely small but they can create several major health concerns for your pets. Depending on the severity of the infestation, your pet can experience allergic reactions or other serious life-threatening illnesses.
According to TIME Magazine, hunting isn't the way to solve issues with animal 'pests'. Some of them carry Lyme disease, transmitted from a black-footed tick, which is know to feed off a deer. Even if they do shoot the deer and kill it, the disease is still there. Maybe not after it's cooked, but the risk still remains.
