The transition from Medieval Europe to the Renaissance and beyond was not easy. Death and loss of power were the results of events such as the Black Death, the downfall in economy was also involved, but in the end it resulted in the discovery of new things. You can relate all of these changes to a modern event, known as the Zika virus. The Zika virus, which has recently invaded the United States, is a disease which has many of the same characteristics as the Black Death.
Have you ever imagined the whitetail deer population being entirely gone? This is completely possible with the increased spreading of Chronic Wasting Disease. Chronic wasting disease is a transmissible spongiform encephalopathy of mule deer, white-tailed deer, elk, moose, and reindeer. Although some people believe baiting deer is not harmful, evidence shows that Chronic Wasting Disease can be spread by baiting so we should prohibit baiting for the deers safety.
The effects of tick-borne diseases are extremely serious. According to the Centers for Disease Control and Prevention (2013), there were three sudden cardiac deaths in the United States from November 2012 to July 2013 that were associated with Lyme Carditis (para. 1). The effects of tick borne diseases can lead to death very quickly. The problem is quite serious because several of the emerging diseases such as the Powassan virus have been found to be devastating. According to Knapp and Rice (2015), over 10 percent of people infected with the Powassan virus are dying due to encephalitis and meningitis caused by the disease (p. 9). Tick-borne diseases have consequential effects and should not be taken lightly. If this problem is not dealt with then tick-borne diseases could be the number one cause of death in the United
In 1937 Eastern Africa, in the country of Uganda, was the first time that West Nile Virus was identified. The disease then quickly spread to the United States, first reaching New York in 1999. Since then, West Nile Virus has spread throughout the world, including most of North America. Today, many cases are reported primarily in the tropics of North America, South America and Asia. (Con. Spr., 1). Due to the fact that mosquitoes carry the most disease in the early fall, the largest amount of people to contract West Nile Virus per year usually occurs in the months of August and September.
The bacterial infection called Lyme disease is spread by deer ticks that are infected with a spiral shaped bacterium called Borrelia Burgdorferi. This disease first occurred in Lyme, Connecticut in 1975, which is why it is named Lyme disease. The ticks are called deer ticks because they normally feed on wild deer. However, deer are not the only animals who carry the ticks. Field mice, raccoons, opossums, skunks, weasels, foxes, shrews, moles, chipmunks, squirrels, and horses are some other animals that also carry them. Most of these animals have
How do hunters help the population? Several natural predators of white-tailed deer occur. Wolves, cougars, American alligators, jaguars, and humans are the most effective natural predators of white-tailed deer. These predators frequently pick out easily caught young or infirm deer, but can and do take healthy adults of any size. Bobcats, Canada lynx, bears, wolverines, and packs of coyotes usually prey mainly on fawns. Bears may sometimes attack adult deer, while lynxes, coyotes, and wolverines are most likely to take adult deer when the ungulates are weakened by harsh winter weather. Many scavengers rely on deer as carrion, including New World vultures, raptors, foxes, and corvids.By the early 20th century, commercial exploitation and unregulated
"Lyme Borreliosis also called Lyme disease, which comes from the deer tick, can cause stiffness, lameness, swollen joints, loss of appetite, fever and fatigue"(canine tick borne disease). Your dog may not show signs right away but signs can start to appear months after the dog has been infected of the disease. The highest risk seasons for Lyme disease is late spring and early fall. Lyme disease is an acute disease which means it's a short but rapid course. The incubation periods for showing clinical signs of being infected are two to five months after been bitten by the tick. Long incubation periods can cause your dog to be on antibodies for a long period of time. You can detect the disease by western
Chlamydia is known as one of the ‘silent’ diseases which can produce no symptoms until much later. Approximately 70-95 percent of woman and 50 percent of men with chlamydia do not observe chlamydia symptoms at all. The symptoms can also be mild and almost unnoticeable or appear once a day. Another reason why symptoms are not the best way to determine the infection is that it is often confused with gonorrhea as the symptoms are very much alike. Asymptomatic nature of chlamydia makes it difficult to estimate how long a person remains infectious and this period is commonly believed to last until the full recovery.
The initial catalyst for the loss of the black footed ferret population was poisoning efforts made in the early 1900s. The target of the poisoning was the prairie dog population, which in turn caused a sharp decline in the black footed ferret population. The most common poisons used by North Dakota residents are zinc phosphide and Rosal. Most people dislike prairie dogs, so they use poison to terminate them. This decline in the prairie dog population in turn affects the black footed ferret population. Other factors that reduce the chances of the black footed ferret’s survival include the conversion of farmland and hunting. (North Dakota Carnivores). The primary reason the black footed ferret is endangered originates from the spread of the plague. According to Oldemeyer, “plague is a flea transmitted disease of rodents caused by the bacterium Yersinia pestis that exists in widespread, discontinuous foci in parts of Africa” (Oldemeyer 28). Specifically, the Bubonic plague has had a lasting effect on rodent populations. An important factor that affects the prairie dog and black footed ferret populations is the density of the host population. The density of the prairie dog population remains more susceptible to the exchange of the plague. The plague moves quickly between colonies with the help of other predators. Fleas primarily transmit the plague to prairie dogs and black footed ferrets. Two main
"Lyme Borreliosis conjointly known as Lyme arthritis, that comes from the Ixodes dammini, will cause stiffness, lameness, swollen joints, loss of craving, fever and fatigue"( Sharp, M.). Your dog might not show signs as shortly as bitten by the tick however signs might seem months when the dog has been infected of the sickness. Late spring and early fall is highest risk seasons for Lyme arthritis. {lyme sickness|Lyme disease|Lyme arthritis|zoonosis|zoonotic disease} is AN acute disease which implies it is a short however fast course. The incubation periods for showing clinical signs of being infected square measure 2 to 5 months when been bitten by the tick. Long incubation amounts will cause your dog to get on antibodies for an extended period
Muscular dystrophy is known as a muscle disorder that is not associated with central nerve abnormality. Disease is supposed to attack the muscles that lack fiber in them. The stability of the sarcolemma muscles depends upon the two main elements, these are dystrophin and dystrophin associated glycoproteins. Pathophysiology of the disease has shown that the gene of dystrophin is present on the chromosome X around the locus p21. In addition to this, there are 3685 amino acids present in this muscle. Although the dystrophin gene contributes to only 0.002% of the muscle protein but it plays a huge role in maintaining the muscle integrity and the lack of dystrophin results in the instability of the cells present in the muscles. Studies have shown that dystrophin also functions in the less active form however the functioning might not be correct because of the leakage present between the cells and the muscle tissues (Goemans et.al 2011).
Bed bugs are scientifically known as Cimex lectularuis (Cimicidae).Bed bugs are small wingless insects that feed on the blood of warm blooded animals. As humans are warm-blooded animals, they are perfect hosts. Some modern bed bugs have learnt to adapt to human environments and live in our nests for example our homes and generally our beds. They have oval shaped flat bodies. They got they name because they prefer areas such as: sofas, bed mattresses and other soft furnishings. Bed bugs are seen as a problem that is slowing increasing they are found in private homes, dormitories, cruise ships, shelters and army barracks. On 12th December 2011 SRI international found out that bed bugs can inbreed and still produce healthy offspring.
Most of us know that Advantix will kill or get rid of one hundred percent of fleas within twenty-four hours. Many of us also realize that this medication will also prevent ticks from thinking that your pet is a hospitable place to hang out. Some of the things that you might not realize are where Advantix really shines.
Ticks will feed on mammals, birds, amphibians and reptiles, but most often mammals are the hosts. Ticks detect heat and carbon dioxide and go toward the source. Once attached to a host they will climb until they reach the highest point or restrictive clothing. The tick then painlessly slips its teeth into the host's skin and begins feeding. Once feeding begins ticks release saliva that literally glues the tick in place so it cannot be removed easily. Once feeding is finished, which can be up to a week, the engorged tick drops off the host, lays eggs, and dies. Depending on the species a single female tick can lay up to 6500 eggs. Ticks are often associated with disease, and rightfully so. Ticks are carriers of two major diseases Lyme disease and Rocky Mountain spotted fever. Ticks of the genus Ixodes (Deer Ticks or black legged tick) are a known carrier and transmitter of Lyme disease, but there could be more. Rocky Mountain spotted fever is primarily transmitted by the American dog tick, but the lone star tick can also transmit the
Sexually Transmitted Diseases (STDs) also known as Sexually Transmitted Infections (STIs) are mostly gotten and acquired via sexual intercourse in an unprotected way in which great numbers of people engage in. There are different types of sexually transmitted diseases, most of which are contracted via the vaginal sex, oral sex or anal sex. Oral STD is usually not limited to age, class or sex and other factors because once a person comes in contact with the fluid which contains the pathogen, he / she is infected with it. The most reoccurring STDs of the mouth are syphilis, Chlamydia and herpes virus. Sexually Transmitted Diseases of the mouth mostly affects the oral region of the body and gives rise to sore and pain in the mouth with fluid discharge in some occasion.
