Plasmodium knowlesi has added to the challenges of prompt and
accurate malaria diagnosis and surveillance. In this study
from Aceh Province, Indonesia, a malaria elimination setting
where P. knowlesi endemicity was not previously known, we
report the laboratory investigation and difficulties
encountered when using molecular detection methods for quality
assurance of microscopically identified clinical cases. From
2014 to 2015, 20 (49\%) P. falciparum, 16 (39\%) P. vivax, 3
(7\%) P. malariae, and 2 (5\%) indeterminate species were
identified by microscopy from four sentinel health facilities.
At a provincial-level reference laboratory, loop-mediated
isothermal amplification ({LAMP}), a field-friendly molecular
method, was performed and confirmed Plasmodium in all samples
though further species-identification was limited by the
unavailability of non-falciparum species-specific testing with
the platform used. At a national reference laboratory, several
molecular methods including nested {PCR} ({nPCR}) targeting
the 18 small sub-unit ({18S}) ribosomal {RNA}, {nPCR}
targeting the cytochrome-b (cytb) gene, a P. knowlesi-specific
{nPCR}, and finally sequencing, were necessary to ultimately
classify the samples as: 19 (46\%) P. knowlesi, 8 (20\%) P.
falciparum, 14 (34\%) P. vivax. Microscopy was unable to
identify or mis-classified up to 56\% of confirmed cases,
including all cases of P. knowlesi. With the {nPCR} methods
targeting the four human-only species, P. knowlesi was missed
({18S} {rRNA} method) or showed cross-reactivity for P. vivax
(cytb method). To facilitate diagnosis and management of
potentially fatal P. knowlesi infection and surveillance for
elimination of human-only malaria in Indonesia and other
affected settings, new detection methods are needed for
testing at the point-of-care and in local reference
laboratories.}

abstract = {Malaria rapid diagnostic tests (RDTs) primarily detect
Plasmodium falciparum antigen histidine-rich protein 2 (HRP2)
and the malaria-conserved antigen lactate dehydrogenase (LDH)
for P. vivax and other malaria species. The performance of
RDTs and their utility is dependent on circulating antigen
concentration distributions in infected individuals in a
population in which malaria is endemic and on the limit of
detection of the RDT for the antigens. A multiplexed
immunoassay for the quantification of HRP2, P. vivax LDH, and
all-malaria LDH (pan LDH) was developed to accurately measure
circulating antigen concentration and antigen distribution in
a population with endemic malaria. The assay also measures
C-reactive protein (CRP) levels as an indicator of
inflammation. Validation was conducted with clinical specimens
from 397 asymptomatic donors from Myanmar and Uganda,
confirmed by PCR for infection, and from participants in
induced blood-stage malaria challenge studies. The assay lower
limits of detection for HRP2, pan LDH, P. vivax LDH, and CRP
were 0.2 pg/ml, 9.3 pg/ml, 1.5 pg/ml, and 26.6 ng/ml,
respectively. At thresholds for HRP2, pan LDH, and P. vivax
LDH of 2.3 pg/ml, 47.8 pg/ml, and 75.1 pg/ml, respectively,
and a specificity >=98.5\%, the sensitivities for
ultrasensitive PCR-confirmed infections were 93.4\%, 84.9\%,
and 48.9\%, respectively. Plasmodium LDH (pLDH) concentration,
in contrast to that of HRP2, correlated closely with parasite
density. CRP levels were moderately higher in P. falciparum
infections with confirmed antigenemia versus those in clinical
specimens with no antigen. The 4-plex array is a sensitive
tool for quantifying diagnostic antigens in malaria infections
and supporting the evaluation of new ultrasensitive RDTs.},

RCD captures local transmission, we genotyped 26

Hospital catchment area between January 2015 and April
2016.Participants from the same RCD event harbored more
genetically related parasites than those from different RCD
events, suggesting that RCD captures, at least in part,
infections related through local transmission. Related
parasites clustered in space and time, up to at least 250 m
from index households. Spatial analysis identified a putative
focal transmission hotspot.The current RCD strategy detects
focal transmission events, although programmatic guidelines to
screen within 140 m of index households may fail to capture
all secondary cases. This study highlights the utility of
parasite genetic data in assessing programmatic interventions,
and similar approaches may be useful to malaria elimination
programs seeking to tailor intervention strategies to the
underlying transmission epidemiology.}",

abstract = {{BACKGROUND}: To better understand transmission dynamics,
we characterized Plasmodium falciparum genetic diversity in
Eswatini, where transmission is low and sustained by
importation. {METHODS}: Twenty-six P. falciparum
microsatellites were genotyped in 66\% of confirmed cases
(2014-2016; N = 582). Population and within-host diversity
were used to characterize differences between imported and
locally acquired infections. Logistic regression was used to
assess the added value of diversity metrics to classify
imported and local infections beyond epidemiology data alone.
{RESULTS}: Parasite population in Eswatini was highly diverse
(expected heterozygosity [{HE}] = 0.75) and complex: 67\%
polyclonal infections, mean multiplicity of infection ({MOI})
2.2, and mean within-host infection fixation index ({FWS})
0.84. Imported cases had comparable diversity to local cases
but exhibited higher {MOI} (2.4 vs 2.0; P = .004) and lower
mean {FWS} (0.82 vs 0.85; P = .03). Addition of {MOI} and
{FWS} to multivariate analyses did not increase discrimination
between imported and local infections. {CONCLUSIONS}: In
contrast to the common perception that P. falciparum diversity
declines with decreasing transmission intensity, Eswatini
isolates exhibited high parasite diversity consistent with
high rates of malaria importation and limited local
transmission. Estimates of malaria transmission intensity from
genetic data need to consider the effect of importation,
especially as countries near elimination. \copyright The

tools for antigen discovery and suitable animal models. The
protein microarray is a high-throughput, sample sparing

We recently demonstrated Qdot-based indirect
immunofluorescence together with portable optical imager
ArrayCAM using single isotype detection could replicate data
using the conventional laser confocal scanner system. We
developed a multiplexing protocol for simultaneous detection
of IgG, IgA, and IgM and compared samples from a controlled
human malaria infection model with those from controlled
malaria infections of Aotus nancymaae, a widely used non-human
primate model of human malaria. IgG profiles showed the
highest concordance in number of reactive antigens; thus, of
the 139 antigens recognized by human IgG antibody, 111 were
also recognized by Aotus monkeys. Interestingly, IgA profiles
were largely non-overlapping. Finally, on the path toward
wider deployment of the portable platform, we show excellent
correlations between array data obtained in five independent
laboratories around the United States using the multiplexing
protocol (R2: 0.60–0.92). This study supports the use of this
platform for wider deployment, particularly in endemic areas
where such a tool will have the greatest impact on global
human health.},

to malaria elimination and are difficult to measure using
traditional surveillance data. To address this challenge, we
systematically collected parasite genetic data and travel
history from thousands of malaria cases across northeastern
Namibia and estimated human mobility from mobile phone data.
We observed strong fine-scale spatial structure in local
parasite populations, providing positive evidence that the
majority of cases were due to local transmission. This result
was largely consistent with estimates from mobile phone and
travel history data. However, genetic data identified more
detailed and extensive evidence of parasite connectivity over
hundreds of kilometers than the other data, within Namibia and
across the Angolan and Zambian borders. Our results provide a
framework for incorporating genetic data into malaria
surveillance and provide evidence that both strengthening of
local interventions and regional coordination are likely
necessary to eliminate malaria in this region of Southern
