#Plasmodium malariae is a parasitic protozoan that causes a type of malaria, known as quartan malaria, transmitted by infected Anopheles mosquitoes. It infects and multiplies in red blood cells, leading to symptoms like fever, chills, and anemia, and is notable for causing chronic, asymptomatic infections and long-lasting relapses. While less studied than P. falciparum and P. vivax, its prevalence is being re-evaluated with modern molecular diagnostics.
Key characteristics
Disease: Causes quartan malaria, with fever paroxysms occurring every 72 hours.
Transmission: Transmitted through the bite of an infected female Anopheles mosquito.
Life cycle: Parasites travel to the liver, mature, and then infect red blood cells, where they multiply.
Infected cells: Prefers older red blood cells, unlike other species that target younger ones.
Symptoms: Fever, chills, headache, fatigue, and anemia.
Chronic infection: Can remain dormant in the liver for years, leading to long-term, asymptomatic infections and relapses.
Diagnosis and challenges
Diagnosis: Traditionally diagnosed by identifying parasites in blood smears, but molecular methods are more sensitive.
Challenges: It is considered a "neglected" parasite, with ongoing research needed to understand its true prevalence and biology.
Drug resistance: Emerging drug resistance is a growing concern.
