HIV is a virus that attacks the immune system and can lead to AIDS (Acquired Immune Deficiency Syndrome). HIV stands for Human Immunodeficiency Virus. It is classified as one …of the types of viruses known as Retroviruses. . However, to answer the question, there is some disagreement on whether a virus is actually a microbe, since definitions of microbes describe them as living organisms, and viruses are not alive. But for practical purposes, especially in medical discussions, viruses are included as a third type of microbe in the world of microorganisms. Microbes are described in the simplest terminology as organisms too tiny to be seen by the human naked eye, and especially those microorganisms that produce disease. Viruses can fit in that definition. But when microbes are described as " living microorganisms", the viruses fall short. The American Heritage Medical Dictionary defines a virus as: . " Any of a large group of submicroscopic agents that act as parasites and consist of a segment of DNA or RNA surrounded by a coat of protein. Because viruses are unable to replicate without a host cell, they are not considered living organisms in conventional taxonomic systems. Nonetheless, they are described as 'live' when they are capable of replicating and causing disease.". (The American HeritageÂ® Medical Dictionary Copyright Â© 2007, 2004 by Houghton Mifflin Company. Published by Hougton Mifflin Company. All rights reserved.) The two types of microbes that include living organisms are the Prokaryotes and the Eukaryotes. As discussed above, often microbes are described as divided into three groups that include Viruses as the third group.
'Protozoans' is the term usually used to talk about the protists that cause malaria in humans or in other vertebrate erythrocytes. Protozoa belong to a large group of eu…karyotic organisms that are single-celled. These are usually microscopic and include amoeba, ciliates, flagellates and sporozoans. In malaria, the protozoans can also be called 'malaria parasites.' Transmission: The sporozoan protozoa that cause malaria are transmitted through a mosquito feeding upon the blood of an infected host and ingesting a number of these parasites. The protozoa develop within the mosquito and are secreted through its saliva to infect other potential hosts when bitten. Once inside a human (or other vertebrate erythrocyte hosts), they can spend a protracted period (from weeks or months to, potentially, years) inside the host's liver and spleen, where they reproduce in the blood (specifically, within the red blood cells, erythrocytes). Malaria is a vector-borne infectious disease caused by any of a number of protozoans spread by the female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria, and they must have been infected through a previous blood meal taken from an infected host. It is common in tropical and subtropical climates in endemic areas including much of Sub-Saharan Africa, Asia and the Americas. These locations have significant amounts of rain fall and consistent hot temperatures. These warm, consistent temperatures and moisture provide mosquitoes with the environment they need to breed continuously year round. Scientific names: The causative organisms include protists of the genus Plasmodium. The three most common organisms in malaria infections are P. vivax, P. ovale, and P. falciparum. Falciparum malaria is the most serious of the three, causing about 80% of all cases of human malaria and 90% of deaths, and is becoming more frequently drug resistant. Another less common type of Plasmodium that can cause malaria is P. malariae. A fifth type, P. knowlesi, is not thought to infect humans. Prevention: To prevent the disease, a person in the areas where these mosquitoes live should reduce the number of bites they receive. Mosquito netting used around beds can reduce the number of mosquitoes and bites and mosquito repellents also help. Symptoms: Symptoms of malaria are fever, shivering, joint pain, vomiting, anemia, hemoglobinuria (when your urine turns red), retinal damage, and convulsions. The classic symptom of malaria is occurrence of sudden coldness followed by rigors (shaking), then fever and sweating lasting four to six hours, which occurs every two days. Other facts: Plasmodium falciparum - the common African type affects 80 - 85% of malaria patients, and is the most severe form of malaria. P. falciparum is also called a 'malign tertian malaria', malign means "evil", and this is the type which most often kills humans. Plasmodium vivax - Milder than Falciparum, is the second most common species to cause the disease malaria. It is also called 'benign tertian malaria', benign means "good", and this type usually doesn't kill humans. Each year, there are approximately 515 million cases of malaria, killing between one and three million people, the majority of whom are young children in Africa. Young children are more prone to getting Malaria than adults are. Ninety percent of malaria-related deaths occur in Africa. Malaria is commonly associated with poverty, but is also a cause of poverty. Malaria is one of the most common infectious diseases and an enormous public health problem. Malaria is a disease which kills a child every 30 seconds across Africa.

The measles virus causes measles
Tetanus is a medical condition characterized by a prolonged contraction of skeletal muscle fibers. The primary symptoms are caused by tetanospasmin, a neurotoxin produced by t…he Gram-positive, obligate anaerobic bacterium Clostridium tetani. Infection generally occurs through wound contamination and often involves a cut or deep puncture wound. As the infection progresses, muscle spasms develop in the jaw (thus the name "lockjaw") and elsewhere in the body. Infection can be prevented by proper immunization and by post-exposure prophylaxis.
Measles is caused by a virus.
Small pox is caused by a virus.
Chlamydia is a sexually transmitted bacterial infection. It is caused by Chlamydia trachomatis, a gram-negative bacteria with a coccoid shape that is an obligate intracellular… parasite. It is curable.
HPV or Human papilloma virus is a virus (as the name suggests) which causes viral infections. It is often associated with STDs (Sexually Transmitted Diseases)
Actually, the flu is the disease (influenza) and the microbes are what cause the disease, not the other way around. The pathogens ("microbes") responsible for the infectious d…isease called influenza are viruses. Viruses are submicroscopic-sized particles that can attach to the cells of a host person, animal, plant or bacteria (they are very small even compared to bacteria and other pathogens that are called microbes*) and replicate within the cells. This eventually destroys the cells and makes us sick until our bodies can use the immune system's processes to get rid of it. * Not all scientists classify viruses as microbes since they are submicroscopic and are non-living organisms.
No, protozoa Trichomonas is a protozoan Trichomonas is a parasite. It is sexually transmitted. It should not be confused with trichinosis which is contracted by ea…ting infected undercooked pork.
Herpes is caused by a virus called herpes simplex virus (HSV). It's not caused by bacteria.
There are six main types of microbes. Fungi is a microbe,with the other five being archaea, bacteria, protista, viruses andmicrobial mergers.
