Protozoans
The single-celled pathogens that are more complex than bacteria and cause diseases like malaria are called protozoa. Protozoa are eukaryotic microorganisms and include various species within the genus Plasmodium, which are responsible for malaria. These organisms can have complex life cycles and often require a vector, such as mosquitoes, for transmission to humans.
Pathogens can cause a wide range of diseases, including bacterial infections such as strep throat, viral infections like influenza, fungal infections such as athlete's foot, and parasitic diseases like malaria. The specific type of disease depends on the pathogen involved and how it affects the body.
There are really 5 main groups; viruses, bacteria, fungi, protozoa (which includes the malaria parasite) and Helminthes (which includes parasites such as flatworms and roundworms). Moulds are classified as fungi.
Some diseases caused by microbes include: influenza (virus), tuberculosis (bacteria), malaria (parasite), and athlete's foot (fungus). Microbes can cause a wide range of illnesses in humans and other organisms.
Pathogens. These are typically bacteria, viruses, fungi, or parasites that can cause disease by invading the body's tissues. Common examples include influenza viruses, E. coli bacteria, and malaria parasites.

Diseases spread by pathogens include a wide range of infections caused by viruses, bacteria, fungi, and parasites. Common examples are influenza and COVID-19 (viruses), tuberculosis and strep throat (bacteria), athlete's foot (fungi), and malaria (parasite). These pathogens can be transmitted through various means, such as direct contact, respiratory droplets, contaminated food or water, and insect bites. Preventive measures like vaccination, hygiene practices, and vector control are essential in controlling the spread of these diseases.
Vectors are living organisms that can transmit pathogens from one host to another. For example, mosquitoes are vectors that can transmit diseases such as malaria and dengue fever by carrying and transmitting the pathogens that cause these diseases. Pathogens rely on vectors to help them spread and infect new hosts.
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.

Culex is a genus of mosquito. It has been known to carry pathogens for West Nile virus, avian malaria, encephalitis, and other diseases.
The five major types of human pathogens are bacteria, viruses, fungi, protozoa, and helminths. Bacteria are single-celled organisms that can cause diseases like strep throat, while viruses, such as the influenza virus, require a host to replicate and can lead to illnesses like the flu. Fungi, including yeast and molds, can cause infections like athlete's foot. Protozoa are microscopic, single-celled organisms that can lead to diseases like malaria, and helminths are parasitic worms that can infect humans, such as tapeworms.
This question is too vague. There are plenty of diseases that are caused by pathogens. E.g. Pneumonia, Pulmonary Tuberculosis, Dengue, Malaria, Pertussis, Leptospirosis, Rabies, STDs, Influenza, Mumps, Schistosomiasis, I could go on.
Diseases are pathological conditions characterized by specific symptoms and signs that disrupt normal bodily functions, often caused by pathogens such as bacteria, viruses, fungi, or parasites. Disease vectors are organisms, typically arthropods like mosquitoes or ticks, that transmit infectious agents from one host to another, facilitating the spread of disease. These vectors play a crucial role in the lifecycle of many pathogens, contributing to the transmission of diseases such as malaria, dengue fever, and Lyme disease. Understanding both diseases and their vectors is essential for effective prevention and control strategies.
Diseases like malaria and human sleeping sickness are caused by protozoan parasites. Malaria is primarily caused by Plasmodium species, which are transmitted to humans through the bites of infected Anopheles mosquitoes. Human sleeping sickness, or African trypanosomiasis, is caused by Trypanosoma brucei, which is transmitted by tsetse flies. Both diseases highlight the significant role of vector organisms in the transmission of these protozoan pathogens.
Pathogens can cause a wide range of diseases, including bacterial infections such as strep throat, viral infections like influenza, fungal infections such as athlete's foot, and parasitic diseases like malaria. The specific type of disease depends on the pathogen involved and how it affects the body.
