P. berghei ANKA Oocyst
Difference from wild-type
RMgm-1585
Normal numbers of oocysts are formed. However, day 10 and 14 oocysts had a reduced size (`60%) compared to wild type oocysts. A large (~10-20-fold) reduction in the numbers of midgut-associated sporozoites was observed. No hemocoel or salivary gland sporozoites were detected.

Imaging data (from Malaria Metabolic Pathways)

Localization of native, functional PfFC in the parasite by immunofluorescence 304 microscopy. Mouse anti-rPfFC IgG, rabbit anti-r(D)PfPBGD (apicoplast marker) IgG and rabbit anti305 rPfHSP60 (mitochondrial marker) IgG were used at 1:200 dilution. The slides were examined using a 306 Fluorescence Microscope (Leica Microsystems) and the images were acquired at 100x 307 magnification using an oil immersion objective and Leica FW 4000 image acquisition 308 software. IE, infected erythrocyte; P, parasite and H, hemozoin. Scale bar = 5 mm.Nagaraj VA, Prasad D, Rangarajan PN, Padmanaban G.

Immunofluorescence images showing multiple localizations of PfTPxGL. PfTPxGL-red signal (anti-mouse Alexa fluor 568), PfPBGD – apicoplast marker, green signal (anti-rabbit FITC), HSP60 – mitochondrial marker, green signal (anti-rabbit FITC). The imaging was carried out with scale bars varying from 5-20 mm The infected RBCs imaged are 6-8 mm across.

Localisation of parasite uroporphyrinogen decarboxylase (PfUROD) by immunofluorescence microscopy. Co-localisation of PfUROD with porphobilinogen deaminase (PfPBGD). Antibodies to recombinant, truncated uroporphyrinogen decarboxylase (r(D)PfUROD) were raised in mice, while PfPBGD and PfHSP60 PF10_0153 antibodies were from rabbit. To study co-localisation, tetramethylrhodamine isothiocyanate (TRITC)-conjugated goat anti-mouse IgG and FITC-conjugated goat antirabbit IgG were used. IE, infected erythrocyte; P, parasite; H, hemozoin. Scale bar = 5 mm. PfUROD co-localised with PfPBGD but not with PfHSP60 (a mitochondrial marker). Therefore, it can be concluded that PfUROD is localised in the apicoplast and not the mitochondrion.Nagaraj VA, Arumugam R, Chandra NR, Prasad D, Rangarajan PN, Padmanaban G.

Localization of porphobilinogen deaminase PfPBGD with d-aminolevulinate dehydratase PfALAD and d-aminolevulinic acid synthase PfALAS in P. falciparum by immunofluorescence. PGDB and PfALAD are localized to the apicoplast. PfALAS is localized to the mitochondrion. IE, infected erythrocyte; P, parasite; H, hemozoin.Sato S, Clough B, Coates L, Wilson RJ.
