There many common pathogens. They all are disease causing. Path- means disease + -ogen meaning causing. The list is very long but here you will find many http://www.dnafrequencies.com/dp/human.shtml
The three most common are the skin, gastrointestinal tract and respiratory tract
The most common route of central nervous system invasion by pathogens is through the bloodstream, crossing the blood-brain barrier. This allows pathogens to enter the brain and spinal cord and cause infections such as meningitis and encephalitis.
Actually it's too cold for most pathogens to survive down there.
The most common reservoir of human pathogens is humans themselves. Many pathogens, including bacteria, viruses, and parasites, are transmitted from person to person, often through direct contact, respiratory droplets, or contaminated surfaces. Additionally, some pathogens can also reside in asymptomatic carriers, further facilitating their spread within populations. Animals and the environment can also serve as reservoirs, but human-to-human transmission remains the predominant source of many infectious diseases.
Most commonly, acute bronchitis is caused by viruses. Bacterial causes are numerous, although difficult to prove because many people are colonized with bacterial pathogens in the mouth or oropharynx.The most common suspected bacterial pathogens include Mycoplasma pneumoniae, Chlamydia pneumoniae, Haemophilus influenzae, and Streptococcus pneumonia.
The most common bacterial pathogens in the U.S. include Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, and Salmonella species. These bacteria can cause a range of illnesses, from skin infections and respiratory diseases to gastrointestinal infections. Additionally, Clostridium difficile is a significant concern in healthcare settings due to its association with antibiotic-related diarrhea. Overall, these pathogens contribute to a considerable burden of morbidity and healthcare costs.
The most common white cell found in the granulocytic series is the neutrophil. Neutrophils are the first responders to infection, carrying out phagocytosis to engulf and destroy pathogens.
The three kingdoms that hold the most common pathogens are Bacteria, Fungi, and Protista. Bacteria include many harmful species responsible for diseases like tuberculosis and strep throat. Fungi can cause infections such as athlete's foot and candidiasis, while Protista includes pathogens like Plasmodium, which causes malaria. Collectively, these kingdoms encompass a wide range of infectious agents affecting human health.
the skin keeps out most pathogens
Neutrophils
Type 1 is the most common of the 3 Polioviruses that causes the Polio disease.
