What is it called when pathogens invade the body?
Antigens: BUT that is only true if the antigens cause a harmful reaction when they invade.
What is specific pathogens?
Specific pathogens are particular types of microorganisms, such as bacteria, viruses, fungi, or parasites, that can cause infectious diseases in humans and animals. These pathogens have unique characteristics and can only infect certain hosts or tissues, leading to specific symptoms and health issues. Identifying the specific pathogen causing an infection is important for proper diagnosis and treatment.
How do pathogens cause disease?
Some produce toxins, while others invade cells or tissues and then produce toxins. Even when localized in the body, such infections can have systemic effects. Symptoms are often a result of the body over-reacting in its own defence.
Pathogens directly attack human tissue?
Pathogens such as bacteria, viruses, and fungi can directly attack human tissue by invading and replicating within the cells or tissues of the body. This invasion can lead to damage of the host tissue, triggering an immune response and causing symptoms of infection.
What type of pathogens causes the fifth disease?
It is a viral infection usually seen in preschool children. It presents with typical upper respiratory syndrome symptoms and can be distinguished by the red "slapped cheek" rash on the face.

What are Frank pathogens?
Frank pathogens are microorganisms that cause disease in a host organism and can lead to noticeable symptoms. They are typically considered "true pathogens" because they have the ability to infect healthy individuals with a robust immune system. Examples include bacteria like Streptococcus pneumoniae and viruses like influenza. Unlike opportunistic pathogens, which only cause disease in immunocompromised individuals, frank pathogens can affect anyone.
What is the difference between virulent and avirulent?
Virulent refers to pathogens, particularly viruses or bacteria, that can cause severe disease or harm to their host, often resulting in significant symptoms and high transmission rates. In contrast, avirulent pathogens are less harmful or non-pathogenic; they may exist without causing disease or may only lead to mild symptoms. This distinction is crucial in understanding disease severity and the immune response elicited by different pathogens.
What are the bacteria and viruses that can make you sick called?
These are called pathogens, which are microorganisms like bacteria and viruses that can cause diseases in humans. Pathogens can infect the body and multiply, leading to illness and symptoms. It's important to maintain good hygiene practices to reduce the risk of exposure to these harmful microorganisms.
What is the meaning of conventional pathogens?
Conventional pathogens refer to microorganisms, such as bacteria, viruses, fungi, and parasites, that are commonly known to cause diseases in humans, animals, or plants. These pathogens have well-documented mechanisms of infection and transmission, often leading to recognizable symptoms and illnesses. Unlike opportunistic pathogens, which primarily cause disease in immunocompromised individuals, conventional pathogens can infect healthy hosts and are typically associated with specific diseases. Understanding these pathogens is crucial for developing effective treatments and preventive measures.

Which two statements are true of foodborne disease pathogens?
Foodborne disease pathogens can be classified into two main categories: bacteria and viruses, with bacteria such as Salmonella and E. coli being common culprits. These pathogens can cause illness when contaminated food is ingested, leading to symptoms like nausea, vomiting, and diarrhea. Proper food handling, cooking, and storage are essential to prevent the spread of these pathogens and ensure food safety. Additionally, some pathogens can survive in various environments, making them a persistent threat in food production and preparation.
Can you Describe one way that pathogens can affect body systems?
Pathogens can cause infections in the body systems by invading tissues and disrupting normal functioning. For example, bacteria can release toxins that damage cells and tissues, leading to symptoms such as fever, inflammation, and organ dysfunction.
The person who harbors infectious organisms?
A carrier is someone who harbors infectious organisms without having symptoms. Carriers together may represent a reservoir of pathogens.
