“…This is important since there have been several recent reports of P. ovale infections in areas of low transmission of malaria in southern and southeast Asia [17,24-26,43]. It is believed that these parasites were introduced into these countries due to increased travel of tourists to or from Africa.…”

BackgroundPlasmodium ovale infection is rarely reported in Malaysia. This is the first imported case of P. ovale infection in Malaysia which was initially misdiagnosed as Plasmodium vivax.MethodsPeripheral blood sample was first examined by Giemsa-stained microscopy examination and further confirmed using a patented in-house multiplex PCR followed by sequencing.Results and DiscussionInitial results from peripheral blood smear examination diagnosed P. vivax infection. However further analysis using a patented in-house multiplex PCR followed by sequencing confirmed the presence of P. ovale. Given that Anopheles maculatus and Anopheles dirus, vectors of P. ovale are found in Malaysia, this finding has significant implication on Malaysia's public health sector.ConclusionsThe current finding should serve as an alert to epidemiologists, clinicians and laboratory technicians in the possibility of finding P. ovale in Malaysia. P. ovale should be considered in the differential diagnosis of imported malaria cases in Malaysia due to the exponential increase in the number of visitors from P. ovale endemic regions and the long latent period of P. ovale. It is also timely that conventional diagnosis of malaria via microscopy should be coupled with more advanced molecular tools for effective diagnosis.

“…There are three separate phases in the VEP waveform: an initial negative deflection (N70), a prominent positive deflection (P100), and a later negative deflection (N155). The peak latency and peak to peak amplitudes of these waves are measured [5]. VEP may be affected by variety of physiological factors including age, sex, visual acuity and pupillary size.…”

“…There have been several recent reports of P. ovale infections in areas of low transmission of malaria in southern and southeast Asia. [2][3][4][5][6] These parasites may have been introduced into Sri Lanka more recently by increased travel of tourists to Africa and by persons involved in commercial enterprises such as the gem trade.…”

Plasmodium ovale, which is generally prevalent only in the African region, has been emerging in the Asian and southeast Asian regions. It has not been reported in Sri Lanka. We report, to our knowledge, an indigenous case of P. ovale infection in Sri Lanka. This patient, who was diagnosed by a polymerase chain reaction, had no history of travel overseas or receipt of a transfusion of blood or any blood products, which makes this a likely case of indigenous transmission. This incidental finding of a P. ovale infection has implications for malaria control in the country and highlights the need to rigorously monitor malaria incidence, as well as prevalent Plasmodium species, with newer and more reliable diagnostics.

Plasmodium ovale malaria in Delhi

Abstract: A case of ovale malaria in a child from Delhi is reported. Urban malaria ecotypes caused by P. ovale has never been seen before. Characteristic morphological features of the parasite in stained blood film confirmed its identification.
