Through much scientific research, a bacteria called Yersinia Pestis was discovered. This bacteria is spread by both animals and insects. This specific bacteria attacks the lymph system causing the infection to spread throughout the body. The reservoirs of this bacteria and disease are mice, rats, squirrels and other small animals. A reservoir is a host of an infection. The vector, meaning carrier, is insects such as fleas and
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

Coccidioidomycosis, or valley fever is a fungal infection caused by Coccidioides immitis spores. Mild cases of this condition are not common and treatment is not generally necessary. However, this disease is often misdiagnosed, due to the fact that you experience only mild or moderate symptoms, and these symptoms often takes 20 years to present. The most severe cases of Coccidioidomycosis causing the infection to spread to other parts of the body through the bloodstream, and people with compromised immune systems are at greatest risk.
Lyme disease is an infection transmitted by deer ticks and black-legged ticks. Individuals usually come in contact with this disease is in wooded or grassy areas that is very prominent in the united states and 60 other countries. It is estimated that in the united states there are more than 300,000 cases per year, but Lyme disease is a very hard infection to diagnose some cases are not accounted for. The symptoms of Lyme disease mimic many other diseases and that is why it can be misdiagnosed most of the time for fibromyalgia, rheumatoid arthritis, Parkinson’s, ALS, alzheimers, or multiple sclerosis. Lyme disease can affect people of all ages but it is most common in people who spend extended periods of time outside or are in
This causes troubles including starvation, freezing to death, or going outside before the winter is over.
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 is 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 blot testing which helps to differentiate the immune response elicited by infection from that induced by vaccination. "Since 1995, the Centers for Disease Control and Prevention (CDC) has recommended that serological testing for Lyme disease consist of a two-tiered approach an initial screening with an enzyme-linked immunoassay (ELISA) or an indirect fluorescent antibody (IFA) test, followed by a Western blot to corroborate a positive or suspect test result(CDC)". Whole cell antigens of the Borreliaburgdorferispirochete are assumed to be rapidlysequestered by the follicular dendritic cells, resulting in long-lived B cell memory. Dogs tested for whole-cell antibodies rarely have a significant decrease in antibody, even as successful treatment lowers the Borreliaburgdorferi
The most logical idea was to lance the boils. Nowadays people would say not to do that because it would spread the infection. This was a time before common sense was still developing. The people thought the bubo was the infection and they thought, kill the infection and you are cured. Another treatment was to hang perfume balls around your neck to purify the air you breathe. The craziest cure was to tie an alive chicken to boil, yet some of population never got sick. Those people were the genetically immune which was only .2% of the population. Even though the doctors of that time tried, 70% of the infected people died
These symptoms include a “high fever, swollen lymph nodes, lethargy, loss of appetite, and swelling of the joints”. The study itself will take four months without space travel time. The reason being four months is to ensure that accurate data will be taken and an adequate amount of time is supplied for data and research. Multiple dogs will need to be taken to the moon to compare the symptoms of different sized dogs and how that affects the study. Lyme disease is most popularly contracted during summer months, ranging during late May through early September (CFSPH). This would be the ideal time to conduct the study because symptoms will be most intense and significant during the early months of the disease. Although many other elements of the study will need to be taken into account, these suggestions are vital to the accuracy and likelihood of a successful
Bed Bugs are on the rise in New York City! The common bed bug (Cimex lectularius) is responsible for the infestation of numerous homes, hotels, and transportation systems in the United States and Internationally. In 2005, bed bugs were an issue of developing countries and occurred most often in travelers (cdc.gov). Now bed bug incursions can be found throughout the United States, more importantly in NYC. Infestations mainly occur in unsanitary conditions or latch on to used furniture and mattresses often discarded on the streets (nyc.gov). Although bed bugs are not known to transmit disease, the nuisance created from sleepless nights, allergic reactions from bites, and the economic hardship motivates people to seek illegal treatment. The emerging
Rocky Mountain Spotted Fever (RMSF) is a tick born potentially fatal disease. It is caused by the bacterium Rickettsia Rickettsii. The CDC has record counts of RMSF since as early as the 1920’s in the US. Most of the cases of RMSF are reported in North and South America. Although it is most common in the Southeastern US, it has also been found in Canada, Mexico, and Central America. Early treatment with the antibiotics Doxycycline and Tetracycline is the key in preventing a fatal outcome. Treatment is most effective if started with five days of onset of symptoms. Early symptoms include high fever and rash. The rash will appear as small, flat, pink and non-itchy spots between two to five days after symptoms have begun and about 90% will develop this. The rash first appears on the wrist and the ankles then spreads in either directions up or down the legs and arms. Other symptoms may include nausea, vomiting, abdominal pain that mimics appendicitis, deep muscle pain, lack of appetite, or red eyes.
"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
Rocky Mountain spotted fever (RMSF) is a tick borne illness that is prevalent in the summer months primarily in the south and central United States. Patients with delayed diagnosis can have increased morbidity, particularly poor neurological outcome. We present a case of a 7-year-old girl with RMSF diagnosed on day 8 of illness who had severe neurological changes and hypotensive shock. Magnetic Resonance Imaging (MRI) of the brain demonstrated “starry sky” appearance with numerous punctate foci of restricted diffusion within the supratentorial brain including the corpus callosum and basal ganglia which has been previously described as characteristic of RMSF. She was treated with intravenous immunoglobulin (IVIG) on the day of admission a presumptive diagnosis of Kawasaki Disease. She ultimately did well with
If you 're anything like me, your dog is your furbaby, and you 'll do anything to protect him or her. But protecting your dog from the elements, particularly from the heat, could not even be on your radar, and it should be.
Ringworm is one of skin disease that is easily transmitted and affect the skin in general. Even some parts of the skin including the skin of the body, part of the nail and the skin of the head can be affected by ringworm. For all this skin disease certainly will lose confidence and also the impact of a very serious skin problems. What if ringworm is already attacking parts of the scalp that are difficult to cure. Ringworm diseases generally can be cured with regular ointment type sold in pharmacies.
