Congratulations Rose

Rose Leke, Emeritus Professor of Immunology and Parasitology at the University of Yaoundé, Cameroon has been awarded the Clara Ludlow Medal by the American Society of Tropical Medicine and Hygiene (ASTMH) during its recent annual meeting. This award recognises honorees for their inspirational and pioneering spirit, whose work represents success despite obstacles and advances the field of tropical medicine. Rose, indeed, is a remarkable woman. Let me tell you why.

Back in the year 2000, I was appointed by the US National Library of Medicine (NLM) as the Communications Director of the Multilateral Initiative on Malaria (MIM). NLM was connecting 19 malaria research institutes throughout Africa to the internet. I decided to investigate the impact of internet access on malaria research as well as on the performance of malaria institutes. Reliable internet was new (and heavenly) and a whole new world of opportunities opened up to us. Now we could organise a symposium in rural Kenya and invite people by email! And invitees would receive their invitation on time and could actually make it to us on time. And image that access to the internet allowed us to be notified about grant opportunities and we could finally submit a grant proposal on time by email rather than snail mail. This all had a significant impact. But as we were all 'new' to the virtual world, only few people knew how to 'google' information. I noticed that malaria professionals all over Africa were spending hours and hours per week to search for the same information. That is when we started with a small team to collect scientific information on malaria and shared that with other malaria professionals, like yourself. In those days Rose had a senior position at the University of Yaoundé, one of the 19 centres in our network. That's how we met. She was among the very first scientists to sign up for our information service called 'the MIMCom Malaria News Update' that eventually evolved into what is now MalariaWorld. And whenever I would meet Rose somewhere around the world she would tell me how important she believed the work of MalariaWorld is. I am proud to say that Rose Leke stood at the cradle of MalariaWorld. On behalf of the entire MalariaWorld team I wholeheartedly congratulate Rose with this so well deserved award! 

Stay healthy, stay safe and enjoy MalariaWorld!

Blog Posts


Blog: Homologous P. vivax malarial recurrences are not necessarily relapses
By Miles Markus
It was pointed out a decade ago that non-reinfection recurrences of Plasmodium vivax malaria caused by parasites that are closely related to those from an earlier time point are highly suggestive of a merozoite origin. This would make them recrudescences (in an unknown proportion of cases), not relapses. In other words, hypnozoites have nothing to do with such a recurrence. Some recurrences that take place after 28 days post infection are also recrudescences (not relapses), as has recently been explained.

Blog: Can P. vivax sporozoites having the same genotype be both tachysporozoites and bradysporozoites?
By Miles Markus
Lysenko et al.’s hypothetical P. vivax tachysporozoites multiply in the liver soon after inoculation into the host, whereas their hypothetical bradysporozoites form hypnozoites, which are the origin of relapses. This "tachy" and "brady" terminology is an extension of usage unrelated to malaria. For a homologous P. vivax malarial recurrence to be a relapse means that firstly, a tachysporozoite(s) will have had to initiate what became a patent infection. But it also means that a sister sporozoite(s) with basically the same genotype must have been, simultaneously, a bradysporozoite(s). This is how hypnozoite-derived recurrent parasites in the bloodstream could in theory come to be genotypically similar to those from an earlier time point. However, do different sporozoites having the same genotype in fact act inconsistently by functioning as either tachysporozoites or bradysporozoites?
