How does the measles pathogen reproduce within the human host?

The measles virus enters the respiratory system through inhalation. It then infects cells in the respiratory tract and lymph nodes, where it replicates. The virus spreads through the bloodstream to other organs, causing symptoms and allowing for further transmission to others.

What was the cure for measles in medieval times?

In medieval times, there was no specific cure for measles. Treatment typically involved rest, staying hydrated, and managing symptoms like fever and rash. Some herbal remedies or bloodletting may have been used as well, but they were not very effective.

Do germs come from eggs?

Germs themselves do not come from eggs. Germs are microscopic pathogens such as bacteria, viruses, and fungi that can cause infections or diseases. Eggs are a food source rather than a source of germs.

How do measles enter your body?

measles are extremely contagious and are spread from person to person through tiny droplets of air (like when someone coughs or sneezes), and spreads throughout the body with the blood circulation

What bacteria is called banquet germs?

"Banquet germs" is not a specific term for any particular bacteria. However, foodborne pathogens such as Salmonella, Escherichia coli (E. coli), and Staphylococcus aureus are commonly associated with food contamination in banquet settings. Proper food handling and hygiene practices are essential to prevent the spread of these bacteria.

Does influenza still happen?

Yes, influenza still occurs every year, typically during the winter months. It is a contagious respiratory illness caused by influenza viruses and can lead to mild to severe symptoms, and occasionally even death, particularly in vulnerable populations such as the elderly, young children, and individuals with underlying health conditions. Vaccination is an effective way to prevent influenza and its complications.

What are the three structural features of a red blood cell?

Red blood cell contain haemoglobin or rather the 4 heme ( iron group ) in each of the 4 polypeptide which can carry up to 4 molecules of oxygen.

Red blood cell also have no nucleus so that it can carry more oxygen molecules.

Red blood cell have a binocular shape that increased its total surface area that suit its function for faster diffusion of gas.

What is a nickname for Lyme disease?

The medical profession's nickname for chronic Lyme disease is the Great Imitator

How does anthrax move?

Anthrax is a deadly disease caused by Bacillus anthracis, a bacterium that forms spores.

There are three types of anthrax: skin, lung and gastrointestinal.

Anthrax from animals. You can become infected with anthrax by handling products from infected animals or by breathing in anthrax spores from infected animal products (like wool, for example). You can also become infected with gastrointestinal anthrax by eating undercooked meat from infected animals.

Anthrax as a weapon. Anthrax also can be used as a weapon. This happened in the US in 2001. Anthrax was spread by sending letters with powder containing anthrax. This caused 22 cases of anthrax infection, including several deaths.

If you touched a dead rat that had rabies could you get rabies?

Yes you can get rabies from a WILD rat.But PET rats do not carry rabies because at the pet store, they receive rabies shots before they are put on sale.This is why you should never touch a wild rat if you ever encounter one. If you somehow get bit by a wild rat seek immediate medical attention as in going to the hospital to get a rabies shot. If a PET rat bites you do not worry because they WILL NOT carry this disease.

Can cocci bacteria be found in animals?

Yes, cocci bacteria can be found in animals. Cocci bacteria are a type of spherical-shaped bacteria that can cause various infections in animals, including skin infections, respiratory infections, and urinary tract infections. It is important for pet owners and livestock producers to be aware of the potential for cocci bacteria in animals and to work with veterinarians to prevent and treat infections.

Bacteria that cause disease in humans live at what temperature?

The average temperature for a human will be the same temperature the bacteria are likely to flourish at which is about 37 degrees celsius or 98 degrees fahrenheit. However, these bacteria can often survive at a variety of temperatures around this mark, often reaching an optimum temperature a few degrees above this.

How is pathogenic bacteria spread?

There are many ways they spread -- you can pass them via contact or droplets, and some can be airborne. Some are spread via vectors (ie mosquitos), and some are in water or food that are ingested. It really depends on what type of pathogenic bacteria you are speaking of.

True or False. Viruses and bacteria are radically different?

True. Viruses are not considered alive and require a host cell to replicate, while bacteria are single-celled organisms capable of independent replication. Additionally, viruses contain genetic material either in the form of DNA or RNA, whereas bacteria have their genetic material in the form of DNA.

Does cowpox go through lytic or lysogenic cycles?

Smallpox goes through a lytic cycle as it does not become dormant.

Name some effects of the bacteria staphylococcus?

Staphylococcus bacteria can cause skin infections, such as boils and impetigo. They can also lead to more serious conditions like pneumonia, toxic shock syndrome, and food poisoning when the bacteria enter the bloodstream or produce toxins.

Give several ways in which the development of antibiotics-resistant pathogen can be slowed or prevented?

Give fewer antibiotics to humans and animals.

Ensure that when antibiotics are given, they are used in sufficiently high dosages and for long enough to kill as many bacteria as possible.

Is measles a DNA virus or RNA virus?

Measles is a very infectious illness caused by a virus - a viral infection caused by the rubeola virus. It is an endemic disease; meaning it is continually present in a community and many people develop resistance.

When did Ada Lovelace get the measles?

Ada Augusta Byron (Lady Lovelace) got the measles in 1829 when she was 14 years old and becomes an invalid for several years

What are the symptoms of giardiasis?

It depends on what type the parasite is and how it behaves. Two examples are:

♦ The parasite can trigger a immune response that your immune system launched to try and get rid of it, and this causes side effects that you can notice, such as high fever and any related symptoms of cold and flu, as the immune system uses the same tactic to get rid of stuff that is not welcome.

♦ The parasite can get away with it and start leeching your life away by drinking your blood, and this can cause at lot of symptoms. Some are headaches, nausea, vomiting, diarrhea, and lots of others depending how the parasite plots its evil plan to wreak havoc with your body.

How do immunizations work?

When your body becomes infected by a pathogenic agent, such as a virus, you produce an immune response which basically destroys the agent as well as any cells that have been invaded and your body is then rid of the infection. This immune response occurs because the body recognises molecules on the surface of the agent as being foreign and then produces cells that are specifically to attack this kind of agent. Some of these cells are kept in the body so that if the same infection strikes again, the body can produce an immune response that is bigger and begins much more quickly so that the individual doesn't suffer the disease. Immunizations effectively mimic the initial infection, causing the individual to produce memory cells so that they are prepared should the actual infection strike. However instead of being given the live infectious agent, which would cause the individual to have the disease, immunizations administer a form of the agent which is in some way deactivated. This means that an immune response will be produced specific to that infection and the individual will be protected from then on but they will not suffer from the disease.

What is the scientific name of kuru?

If you are talking about the Kuru Disease, the scientific name is Creutzfeldt-Jakob

What do viruses do to your body?

Viruses affect the body in many ways. You have to name a specific virus and then somebody can answer it spcifically. Viruses in general can cause a lot of harm for your body and sometimes even kill you!! Next time just remember to state a specific virus and it will be very easy to answer that question.

Bye!! Hope this was what you were looking for.
