What lab diagnosis can detect Plasmodium?
PCR is most useful for confirming the species of malarial parasite after the diagnosis has been established by either smear microscopy or RDT. Serology detects antibodies against malaria parasites, using either indirect immunofluorescence (IFA) or enzyme-linked immunosorbent assay (ELISA).
What are the diagnostic features of Plasmodium falciparum?
Diagnostic Features of Plasmodium Species in Blood Smears
| Characteristic | Plasmodium vivax* | Plasmodium falciparum |
|---|---|---|
| Infected red blood cells (RBCs) enlarged | Yes | No |
| Schüffner dots‡ | Yes | No |
| Maurer dots or clefts | No | Yes§ |
| Multiple infections in RBCs | Rare | Yes |
How can a CBC detect malaria?
A blood smear test can help diagnose malaria….Other tests
- Polymerase chain reaction (PCR). This test detects parasite nucleic acids and identifies the species of malaria parasite.
- Complete blood count (CBC). This checks for anemia or evidence of other possible infections.
- A blood glucose test.
What is the diagnosis of malaria?
The gold standard for the diagnosis of malaria involves microscopy with visualization of Giemsa-stained parasites in a blood sample. Species determination is made based on morphological characteristics of the four species of human malaria parasites and the infected red blood cells.
What is the meaning of Plasmodium malariae?
Plasmodium malariae is a parasitic protozoan that causes malaria in humans. It is one of several species of Plasmodium parasites that infect other organisms as pathogens, also including Plasmodium falciparum and Plasmodium vivax, responsible for most malarial infection.
What is the diagnostic stage of Plasmodium falciparum?
P. falciparum assumes several different forms during its life cycle. The human-infective stage are sporozoites from the salivary gland of a mosquito. The sporozoites grow and multiply in the liver to become merozoites….
| Plasmodium falciparum | |

| Family: | Plasmodiidae |
| Genus: | Plasmodium |
| Species: | P. falciparum |
| Binomial name |
What does Plasmodium malariae cause?
Plasmodium falciparum is the type of malaria that most often causes severe and life-threatening malaria; this parasite is very common in many countries in Africa south of the Sahara desert. People who are heavily exposed to the bites of mosquitoes infected with P. falciparum are most at risk of dying from malaria.
Which WBC is increased in malaria?
WBC count in the body can vary during the different stages of malaria infection. Leucopenia (reduction in WBCs) is common during acute malaria, whereas leucocytosis (increase in WBCs) can occur during severe malaria.
What is CBC and MP test?
This test measures several components of the blood including red blood cells (RBCs) which carry oxygen, white blood cells (WBCs) which fight infection, haemoglobin (Hb) which is the oxygen-carrying protein in red blood cells, haematocrit which is the ratio of the volume of red blood cells to the total volume of blood.
What are the differential diagnosis of malaria?
Others
| Differential diagnosis of Malaria | Symptoms | Diagnosis |
|---|---|---|
| Brucellosis | ✔ | Relative lymphocytosis |
| Typhoid fever | ✔ | Decreased hemoglobin |
| Malaria | ✔ | Microcytosis, elevated LDH |
| Tuberculosis | ✔ | Mild normocytic anemia, hyponatremia, and hypercalcemia |
What is the gold standard for malaria diagnosis?
Which disease is caused by Plasmodium malariae?
Malaria is caused by a single-celled parasite of the genus plasmodium. The parasite is transmitted to humans most commonly through mosquito bites.
What is diagnostic stage of malaria?
Diagnosis of malaria using serological methods is usually based on the detection of antibodies against asexual blood stage malaria parasites. Immunofluorescence antibody testing (IFA) has been a reliable serologic test for malaria in recent decades [50].
