A rash can be an indicator of a fungal infection of the skin. Prion disease A prion is a protein that contains no genetic material.
Brucellosis is a bacterial disease that affects the ability of animals to reproduce. The disease can be transmitted to humans through contact with recently aborted tissue from infected animals or consumption of unpasteurized raw milk.
Dogs that are infected might have decreased appetite, weight loss, behavioral changes, and lack of energy, but most dogs infected with brucellosis show no signs of illness. Brucellosis affects the reproductive organs and can cause early-term deaths of developing puppies. People who are infected with brucellosis will usually become sick within weeks of exposure.
Sick people will have flu-like symptoms that last weeks. Sometimes brucellosis can become a chronic illness that can be difficult to treat. Many species of Capnocytophaga bacteria live in the mouths of dogs and cats. These bacteria do not make dogs or cats sick. Rarely, Capnocytophaga can spread to people through bites, scratches, or close contact from a dog or cat and cause illness.
Most people who have contact with a dog or cat do not become sick. People with weakened immune systems who have difficulty fighting off infections for example, people with cancer or those taking certain medications such as steroids are at greater risk of becoming ill.
Cryptosporidium is a parasitic disease that is transmitted through contaminated food or water from an infected person or animal. Cryptosporidium illness in dogs is rarely seen, but they can carry the germ without showing any signs of illness.
Cryptosporidium can cause profuse, watery diarrhea with cramping, abdominal pain, and nausea in both animals and people. Illness in people is usually self-limiting and lasts only days, but can become severe in people with weakened immune systems.
Echinococcosis is a parasitic disease caused by eating or drinking food and water contaminated with a specific type of tapeworm eggs or through contact with an infected animal. Dogs become infected by eating tissue of an infected animal.
Dogs rarely show any signs of disease, but if they are infected with a large number of worms, dogs can have diarrhea and enteritis. Although Echinococcus invades many different organs of the body, most people who are infected with the disease will not have any signs of illness for years.
Symptoms start when the slow-growing cysts become large enough to press on the organs they have invaded. The tapeworms grow slowly in several different organs of the body, most commonly the liver and lungs.
Ehrlichiosis is a bacterial disease that affects animals and people and is transmitted by ticks. Dogs show variable signs that include depression, loss of stamina, stiffness and reluctance to walk, and coughing. People show similar signs and symptoms, which include fever, headache, chills, muscle pain, nausea, vomiting, diarrhea, and rash.
Giardia is a parasite that causes diarrhea in animals and people. Giardia is transmitted to animals and people through food or water contaminated with stool.
Symptoms in animals and people include diarrhea, greasy stools, and dehydration. People can also have abdominal cramps, nausea, and vomiting.
Symptoms can last weeks. Leishmaniasis is a protozoan disease of people and animals. It is transmitted by sandflies and is uncommon in North America.
The two forms of the disease are visceral and cutaneous. The cutaneous form of leishmaniasis is most common in people and appears as one or more painless ulcers on the skin. Visceral leishmaniasis is less common and is characterized by fever, weight loss, enlarged spleen, and anemia.
Dogs can develop both forms at the same time and have a variety of symptoms. Leptospirosis is a bacterial disease of people and animals that is transmitted through contaminated water and urine or other body fluids from an infected animal.
It is difficult to detect early stages of leptospirosis in animals, but the disease can lead to kidney and liver failure if left untreated. People who become infected with leptospirosis might not have any signs of the disease.Pattern of the pandemic.
The bubonic plague was endemic in populations of infected ground rodents in central Asia, and was a known cause of death among migrant and established human populations in that region for heartoftexashop.com influx of new people due to political conflicts and global trade led to the distribution of this disease throughout the .
Pneumonic, septicemic, and bubonic plague are transmitted to humans from fleas that have fed on infected rodents. Plague symptoms include swollen lymph nodes, fever, and chills. Get the facts on the history of plague (Black Death).
The bubonic plague causes are bacteria called Yersinia pestis. Usually, the bacteria is spread through the bites of infected fleas or rodents. However, other animals can carry this bacteria, too, such as prairie dogs, lice, and chipmunks. Transmission of these droplets is the only way that plague can spread between people.
This type of spread has not been documented in the United States since , but still occurs with some frequency in developing countries. Bubonic plague is an infection of the lymphatic system, usually resulting from the bite of an infected flea, Xenopsylla cheopis (the rat flea).
In very rare circumstances, as in the septicemic plague, the disease can be transmitted by direct contact with infected tissue or exposure to the cough of another heartoftexashop.com flea is parasitic on house and field rats, .
An infection happens when a foreign organism enters a person's body and causes harm. The organism uses that person's body to sustain itself, reproduce, and colonize.
