Protozoa and the Illnesses They Cause
Nov 26, · Symptoms such as fever, malaise, severe skin rashes, and even tachycardia are signs of diseases caused by protozoa. Above all, there are two ways protozoan pathologies occur. For one, by consuming contaminated water. Secondly, by getting bitten by an invertebrate that has these microorganisms in its body. Malaria, which is caused by the apicomplexan protozoan Plasmodium, remains a serious disease despite measures that can be taken to control and eradicate the mosquito vector host and despite the availability of an array of antimalarial drugs.
Symptoms such as fever, malaise, severe skin rashes, and even tachycardia are signs of diseases caused by protozoa. Above all, there are two ways protozoan pathologies occur. For one, by consuming contaminated water. Secondly, by getting bitten by an invertebrate that has these microorganisms in its body.
Various scientific studies have talked about these zoonotic-type diseases. Do you know caise a protozoan is? Do you know the most typical diseases that these living beings cause? Understanding the epidemiological dynamics of pathogens is essential in order to learn how to avoid them. Keep reading this article to learn more! Protozoa are heterotrophic microorganismswhich means they feed on organic matter.
They live in humid environments; either in completely aquatic environments or in superficial films of water on land. According to sources such as Clinical Microbiology Reviewsthe protozoa kingdom is made up of 18 different phyla that comprise around 30, species. The most widely used classification divides these characteristic microorganisms into four groups. Their size varies from 10 to 50 micrometers. Additionally, they move through liquids by using appendages what time does the bruins game start tonight flagella.
Studies say that many species are free-living, while others have specialized in parasitizing humans and other vertebrates wild or of agricultural interest.
Due to the nature of the causative pathogens, protozoan diseases are more of a problem in low-income countries. These can occur in all types of population groups regardless of sex or age. This value is quite high when you take into account the research sample size. What to do for sore shoulder statistical samples further support the vulnerability of infants to these gastrointestinal protozoa.
This high prevalence of pathogenic protozoa has everything to do with the lack of sanitation and fecal contamination of water for public consumption.
Prootozoa species Toxoplasma gondii, an obligate intracellular parasite, is the cause of this disease. On the other hand, in high-income countries, the most common method of contagion is through contact with protozooa not treated by veterinarians. This is a diarrheal disease caused by the previously mentioned protozoan, Giardia lamblia. It lives in the small intestine of the infected person and is transmitted through the feces of a sick animal or human being.
Giardiasis has symptoms such as abdominal pain, bloating, and profuse diarrhea. Read also: The symptoms and treatment of giardiasis.
The infection is caused by the bite of a tsetse fly that contains the pathogen. Its symptoms include skin ulcers in the first instance, followed by fevers, headaches, anemia, weakness of the circulatory system, and weight loss. Malaria is a pathology caused by the protozoan parasite of the Plasmodium genus. The fause transmitting vectors of this parasite are mosquitoes of the Anopheles genus.
These harbor the protozoan in their body and pass it into the human bloodstream with the bite. Symptoms vary widely, from fevers and hiw to nausea, vomiting, and coughing up blood. Read also: The main pathogens during summer. Protozoa are microorganisms that occur in a general way in all environments. Furthermore, many of the aforementioned pathologies occur in tropical or very hot countries since invertebrates, such as mosquitoes and fliesare the main transmission vectors.
Although there are specific medications for each of the pathologies we mentioned, good prevention is always key. For this, not consuming non-potable water or food without sanitary control is essential.

Diseases caused by protozoa
The disease Giardia is caused by a flagellate protozoan of the same name. It moves through the gut causing the nasty symptoms of that disease. Flagellates can have from one to many flagella. Apr 22, · Protozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector (for example, through the bite of a mosquito or sand fly). The protozoa that are infectious to humans can be classified into four groups based on their mode of movement: Sarcodina – the ameba, e.g., Entamoeba. Plasmodium protozoa cause malaria. The parasites are spread by a mosquito vector. Parasites enter a host’s blood through the bite of an infected mosquito. The parasites infect the host’s red blood cells, causing symptoms such as fever, joint pain, anemia, and fatigue.
A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Entamoeba histolytica is a protozoan. A microscope is necessary to view this parasite. Credit: CDC. Protozoa are microscopic, one-celled organisms that can be free-living or parasitic in nature.
They are able to multiply in humans, which contributes to their survival and also permits serious infections to develop from just a single organism. Protozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector for example, through the bite of a mosquito or sand fly.
The protozoa that are infectious to humans can be classified into four groups based on their mode of movement:. Helminths are large, multicellular organisms that are generally visible to the naked eye in their adult stages. Like protozoa, helminths can be either free-living or parasitic in nature.
In their adult form, helminths cannot multiply in humans. There are three main groups of helminths derived from the Greek word for worms that are human parasites:. Although the term ectoparasites can broadly include blood-sucking arthropods such as mosquitoes because they are dependent on a blood meal from a human host for their survival , this term is generally used more narrowly to refer to organisms such as ticks, fleas, lice, and mites that attach or burrow into the skin and remain there for relatively long periods of time e.
Arthropods are important in causing diseases in their own right, but are even more important as vectors, or transmitters, of many different pathogens that in turn cause tremendous morbidity and mortality from the diseases they cause.
Parasitic infections cause a tremendous burden of disease in both the tropics and subtropics as well as in more temperate climates. Of all parasitic diseases, malaria causes the most deaths globally. Malaria kills more than , people each year, most of them young children in sub-Saharan Africa. The Neglected Tropical Diseases NTDs , which have suffered from a lack of attention by the public health community, include parasitic diseases such as lymphatic filariasis , onchocerciasis , and Guinea worm disease.
The NTDs affect more than 1 billion people worldwide, largely in rural areas of low-income countries. These diseases extract a large toll on endemic populations, including lost ability to attend school or work, stunting of growth in children, impairment of cognitive skills and development in young children, and the serious economic burden placed on entire countries. However, parasitic infections also affect persons living in developed countries, including the United States.
