(mă-lār’ē-ă), A disease caused by the presence of the sporozoan Plasmodium in human or other vertebrate erythrocytes, usually transmitted to humans by the bite of an infected female mosquito of the genus Anopheles that previously sucked blood from a person with malaria.
Why is malignant malaria called black water fever?
Blackwater fever has a high mortality. Its symptoms include a rapid pulse, high fever and chills, extreme prostration, a rapidly developing anemia, and the passage of urine that is black or dark red in colour (hence the disease’s name).

What is the difference between Tertian and quartan malaria?
Each of the four types of malarial parasite cause a characterisitic periodicity of fever. This has led to the description of malaria as being either tertian, where fever occurs every third day i.e. day 1,3,5 etc. or quartan where fever occurs every fourth day ie on day 1,4,7 etc.

Low-grade fever
The medical community generally defines a fever as a body temperature above 100.4 degrees Fahrenheit. A body temp between 100.4 and 102.2 degree is usually considered a low-grade fever. “If the temperature is not high, it doesn’t necessarily need to be treated with medication,” Dr. Joseph said.

Malaria is a disease caused by a parasite with five species known to infect humans, while yellow fever is caused by a virus. Though the infection of both the diseases can be fatal, death rates for malaria are significantly higher.

(of a fever, ague, etc.) characterized by paroxysms that recur every fourth day, both days of consecutive occurrence being counted. noun. a quartan fever or ague.
How frequently do the fevers associated with Tertian malaria occur?
In P vivax and P ovale malaria, a brood of schizonts matures every 48 hr, so the periodicity of fever is tertian (“tertian malaria”), whereas in P malariae disease, fever occurs every 72 hours (“quartan malaria”).
Who is the causative organism of quartan malaria fever?
The causative agent of quartan malaria is Plasmodium malariae.
What are merozoites?
Medical Definition of merozoite
: a small amoeboid sporozoan trophozoite (as of a malaria parasite) produced by schizogony that is capable of initiating a new sexual or asexual cycle of development.
Can P vivax cause blackwater fever?
Blackwater fever is caused by heavy parasitization of red blood cells with Plasmodium falciparum. However, there have been other cases attributed to Plasmodium vivax, Plasmodium malariae, Plasmodium knowlesi.
What diseases are treated with quinine?
Quinine is used to treat malaria caused by Plasmodium falciparum. Plasmodium falciparum is a parasite that gets into the red blood cells in the body and causes malaria. Quinine works by killing the parasite or preventing it from growing.
Is urine black water?
Blackwater can contain feces, urine, water and toilet paper from flush toilets. Blackwater is distinguished from greywater, which comes from sinks, baths, washing machines, and other kitchen appliances apart from toilets. Greywater results from washing food, clothing, dishes, as well as from showering or bathing.
What causes benign Tertian?
Benign tertian malaria is an acute febrile illness caused by Plasmodium vivax. P. vivax is the most widespread prevalent plasmodium species and usually has a benign course with no complications or death.
Which is the treatment of choice for benign tertian malaria?
Regardless of whether malaria was due to Plasmodium falciparum or Plasmodium vivax, chloroquine was the drug of choice, because it has the major advantages of being cheap, safe, and effective.
Can Plasmodium vivax cause cerebral malaria?
vivax infection can also present as cerebral malaria. Clinical data provided by Kochar et al, indicates that P. vivax can cause both sequestration-related and nonsequestration-related complications of severe malaria, all of which are commonly associated with P. falciparum infections.
What is hemoglobinuria?
If the red blood cells break down in the blood vessels, their parts move freely in the bloodstream. If the level of hemoglobin in the blood rises too high, then hemoglobin begins to appear in the urine. This is called hemoglobinuria.

Cerebral malaria is the most severe neurological complication of infection with Plasmodium falciparum. With >575,000 cases annually, children in sub-Saharan Africa are the most affected.
How do merozoites invade RBC?
Invasion is completed by resealing of the RBC membrane, and completion of the processing and shedding of merozoite surface proteins (image modified from Richards and Beeson 2009).
Why does Plasmodium invade red blood cells?
Parasite invasion of red cell occurs when the extracellular form of the parasite, the merozoite, released following rupture of an infected red cell attaches to the surface of an uninfected red cell.
Which RBC is infected in P. vivax?
Rather than using mature red blood cells, vivax merozoites preferentially invade immature red blood cells, known as reticulocytes.
