Antigens are molecules that can trigger an immune response in the body. While some antigens may come from pathogens such as bacteria, viruses, or other harmful substances, not all antigens are pathogens. Antigens can also come from harmless substances like pollen, dust, or certain foods. **

Yes, running a dishwasher at 70°C can effectively kill most pathogens. The high temperature helps to sanitize dishes and utensils by destroying harmful bacteria and germs. However, it is important to note that some heat-resistant pathogens may still survive at this temperature, so it is recommended to use a combination of hot water and detergent for thorough cleaning. **

The pathogens of polio are polioviruses, which are part of the enterovirus genus. There are three serotypes of poliovirus: type 1, type 2, and type 3. These viruses are transmitted through the fecal-oral route, typically entering the body through contaminated food or water. Once inside the body, the virus multiplies in the intestines and can then spread to the nervous system, leading to symptoms of polio. **

No, most pathogens cannot survive in boiling water. Boiling water at 100 degrees Celsius (212 degrees Fahrenheit) is an effective way to kill most bacteria, viruses, and parasites that may be present in the water. This is why boiling water is a common method for water purification in areas where the water may be contaminated with pathogens. However, some spore-forming bacteria and certain viruses may be more resistant to boiling water, so it is important to follow proper water treatment guidelines to ensure complete disinfection. **

Pathogens can be transmitted through pigeon droppings in several ways. When the droppings dry, they can turn into dust that can be inhaled, potentially allowing pathogens to enter the respiratory system. Additionally, rain can wash the droppings into water sources, contaminating them with pathogens. Direct contact with pigeon droppings can also lead to transmission of pathogens, especially if the droppings come into contact with open wounds or mucous membranes. Overall, the transmission of pathogens through pigeon droppings can occur through inhalation, ingestion, or direct contact. **

No, antigens and pathogens are not the same thing. Antigens are molecules that trigger an immune response in the body, while pathogens are microorganisms that can cause disease. Pathogens can contain antigens that the immune system recognizes and responds to in order to fight off the infection. In summary, antigens are a broader category that includes pathogens as one type of antigen. **

Some common human pathogenic pathogens include bacteria such as Escherichia coli, Staphylococcus aureus, and Streptococcus pneumoniae. Viruses like Influenza virus, Human Immunodeficiency Virus (HIV), and Hepatitis B virus are also common pathogens. Fungi such as Candida albicans and parasites like Plasmodium falciparum are known to cause diseases in humans. These pathogens can lead to a variety of illnesses ranging from mild infections to serious diseases. **

One can find many bacteria, viruses, and pathogens in various places such as hospitals, where sick individuals are treated and where there is a higher risk of exposure to infectious agents. Additionally, crowded public spaces such as public transportation, airports, and schools can also harbor a high concentration of bacteria, viruses, and pathogens due to the close proximity of people. Other places where these microorganisms can be found include contaminated water sources, food processing facilities, and areas with poor sanitation and hygiene practices. **
