Abstract
Background: The morphology of red blood cells (RBCs) is altered significantly during the maturation stages of malaria parasites, which include ring, trophozoite, and schizont. There is dissimilarity in terms of the morphological characteristics of parasitized RBCs infected by the 4 species of Plasmodium, including falciparum, vivax, malariae, and ovale. This makes the process of diagnosis very difficult, which may lead to a wrong treatment method and substantial damage to the health of the patient. An innovative technique in introduced that accurately defines the shape of parasitized RBCs at each stage of infection as a potential method of diagnosis. Methods: Giemsa-stained thin blood films were prepared using blood samples collected from healthy donors as well as patients infected with P. malariae and P. ovale. The diameter and thickness of healthy and infected RBCs at each stage of infection were measured from their optical images using Olysia and Scanning Probe Image Processor (SPIP) software, respectively. A shape equation was fitted based on the morphological characteristics of RBCs, and their relative 2-dimensional shapes were plotted using Wolfram mathematica.
Results: At the ring stage, the thicknesses of RBCs parasitized by P. malariae (Pm-RBCs) and P. ovale (Po-RBCs) increased by 42% and 51%, respectively. Both Pm-RBCs and Po-RBCs remained nearly biconcave throughout parasite development even though their volumes increased.
Conclusions: It is proposed that the morphology-based characterization technique introduced here could be used to intensify the accuracy of the Giemsa staining diagnosis method for the detection of the Plasmodium genus and infection stage. Based on the significant morphological alterations induced by different Plasmodium species, the results may also find practical use for faster prediction and treatment of human malaria.

If yes, please write the names of the organizations in the box : Word health organization, National Institute of Malaria Research, Field Unit, DHS, Campal, Panaji- 403001&Goa Medical College and Hospital,National Vector Borne Disease control programme.
What were the responses to your talking points? Were specific questions or concerns raised? : It was interested for participants in the congress, because it was about a morphological study. Authorities asked me some question about: How we conduct the study/What was the results? and How we can use this occlusion for future?

Please inform us if there are any follow up actions we need to talk with the members of the congress : because there was an activity in the same way , Dr. Neena Valecha asked me for going to New Delhi for more researcher about continues culture for Plasmodium falciparum to produce gametocyte in culture. In fact in Iran we are able to do continues culture but we are not able produce gametocyte in the same medium so it is very important to complete our potential power for research in the future.
If it is possible I'm encourage to continue this collaboration

Your experiences about the travel processes(Providing ticket, accommodation,...) : It’s a proud for me to declare that I could participate in Xth Joint Conference of ISMOCD & IAE Goa. For this reason an abstract with title:
“Diagnosis of red blood cells parasitized by Plasmodium malariae and Plasmodium ovale using a morphology-based method: a preliminary study” was offered by me as first author and it was an interesting subject for precipitants in this conference.
The main subject in the congress was about accurate diagnosis and regular reporting of occurrence about all diseases including Malaria and other vector born diseases (such as: Visceral Leishmaniasis, Dengue fever, fillarisis and etc.) to facilitate control measures and prevention of its further spread.
We provided ticket and hotel reservation from a local agency in Tehran. After arriving to Goa registration fee was paid on site.
The subjects were discussed in the congress were more or less similar to the problems we have in Iran, But in our country Iranian society was more success to combat against some of them like malaria and we could challenge with scientists to offer them new approaches to overcome the problem. Moreover some unknown diseases were discussed in the congress like Chikungunya and performed new information about them to us.
Please give a briefing of your own observations and outcomes of the congress: : . Nowadays migration and travels has become larger and easier for every person in the world, so Iranian physician may be encountered with new cases of these unknown diseases. Then it is important for researchers and medical colleagues in Iran to have more and more knowledge about communicable diseases in worldwide especially in Asia. One of our duties after coming back to the country is informing medical researches about them.
I’m sure that recommendations of this conference provided appropriate guidelines for drafting healthy public policy for control of communicable and non communicable diseases in the country.
