INDEX OF MINOR PAGES
A
Accolé form - the "edge" parasite, most closely associated with P.falciparum though certainly not restricted to this species
Aldolase - see Pan Malarial Antigens
Amoeboid forms - a particular description applied to the irregular solid late trophozoites from P.vivax, very typical of the species
Angular forms - a solid late trophozoite form that appears angular in shape, most closely associated with P.malariae
Appliqué” form - see accolé form
B
Banana gametocyte - the curved elongated form of the gametocyte of P.falicparum
Band form - in P.malariae (and also P.knowlesi) the late trophozoite may form band across the infected erythrocyte
Basket form - angular or irregular cytoplasm encloses the vacuole, with pigment evident, mainly seen in P.malarie
C
Central chromatin dot - the chromatin dot appears to lie within the vacuole of a ring form, may be more frequent in P.malariae'
Circulating schizonts in P.falciparum - a potential feature of severity in this species
Comet form - a feature of P.ovale where the combination of elongation and fimbriation is said to resemble of comet
Crenation of red cells - the red cells in P.falciparum may become crenated see Size and shape of red cells
Clearance of parasite antigens from blood - following successful treatment parasite antigens are cleraed at different rates.
Cytoplasmic dots - an overview of the dot-like structures present in malaria species
D
Daisy head schizont - schizonts with a central area of pigment surrounded by petal like merozoites
Distrorted erythrocyte shape - see Size and shape of red cells
Double chromatin dot forms - trophozoites in which the chramatin forms two roughly equal dots
Dual species infection - in some instances infection occurs simultaneously with two different species
E
Ex-flagellation - see Storage changes
Edge form - see Accolé form
F
Fimbriation - irregular projections of the erythrocyte membrane seen mainly in P.ovale
H
Haemozoin - see Malaria pigment
Histidine-rich protein 2 (HRP2) - A specific antigen for P.falciparumused in RDT tests.
Histidine-rich protein 2 gene deletions (HRP2) - Deletion mutations specific or this gene can affect RDT sensitivity
J
James' dots - frequent red-purple dots in the cytoplasm of P.ovale infected erythrocytes (see Cytoplasmic dots)
L
LDH pan-malarial form - see Pan-malarial antigens
Lactate Dehydrogenase (species-specific form) (pLDH/pvLDH forms) - the malaria-species specific form of LDH, may have species-sepicicity
M
Malaria pigment - brown or gold masses within the cytoplasm of infected red cells or overlying parasites
Maurer's dots and clefts - blue dots or short linear structures seen in P.falciparum infected red cells
Macrogametocytes & Microgametocytes - male and female forms of malarial gametocytes differ in size
Multiple parasites - more than one parasite seen within an infected erythrocyte, more frequently seen in P.falciparum
O
P
Pan-malarial antigens (pAldolase and p-panLDH)
Phagocytosed malaria pigment - free malaria pigment is phagocytosed by neutrophils or monocytes
Pigment - see Malaria pigment
Prozone-like effect - A rare but important cause of RDT failure
R
RDT: test failure - practical causes for a failure of an RDT test to produce a control line
RDT: cross-reactive antibodies - causes of a "false positive" RDT result
RDT: detection limits -sensitivity limitations of these tests should be understood
RDT detection sensitivity for different species - limitations of detection for individual malarial species
RDT: causes of poor performance -sensitivity limitations of these tests should be understood
Ring forms - probably the most familiar and frequently encountered parasite form
S
Schüffner's dots - frequent red-purple dots in erythrocytes infected by P.vivax (see Cytoplasmic dots)
Schizont - clinical images - an image guide to the cycles of replication leading to schizont release
Sinton and Mulligan's stippling - cytoplamic dots seen in P.knowlesi (see Cytoplasmic dots)
Size and shape of red cells - the size and shape of red cells containing parasites varies between species
Staining pH - the pH of the malaria stain can significantly affect the parasite and erythrocyte appearances
Storage changes - if there is delayed-spreading recognisable changes may occur as parasites continue to develop.
Synchronicity of malaria parasite development - sometimes a single parasite stage is found in blood
Z
Ziemann's dots - faint cytoplasmic dots that may be detected in P.malariae (see Cytoplasmic dots)
