Kenyan researchers discover microbe that blocks transmission of malaria

Cape Town - Scientists in the fight against malaria have adopted a new approach which has yielded breakthrough results: by protecting mosquitoes, people are protected.
They have discovered a microbe called Microsporidia MB, which lives in mosquitoes' stomach and sexual organs and prevents the insects from being infected with malaria and therefore from transmitting the disease to humans.
This is according to scientists from the International Centre of Insect Physiology and Ecology (ICIPE) based in Nairobi, in collaboration with their fellow scientists from the University of Glasgow in the UK, who made the fundamental discovery, which has the possibility to eradicate malaria completely.
The research was primarily conducted on mosquitoes from Lake Victoria, which borders Uganda, Kenya, and Tanzania. ICIPE’s research found approximately 5% of mosquitoes in this area carry the natural microbe. They hope to breed more mosquitoes with the microbe or to infect male mosquitoes with the microbe in order for it to be passed on to female mosquitoes during reproduction.
Lilian Mbaisi, a Kenyan academic who is currently pursuing her Master of Science (MSc) at the University of Nairobi and a member of the research team, explained: "We were excited to find that the Microsporidia MB symbiont is transmitted from mother mosquitoes to their offspring, and that the microbe does not compromise the ability of mosquitoes to survive.” 
The research paper published on Nature.com on Monday cites how current methods have reduced malaria infections by approximately 40% since 2015. However, the disease still poses a major threat to the health and economic development of countries where malaria is a risk, and highlights how the fight against malaria has stagnated since.
Physical measures of bed nets, insecticides and treatment once a person is infected will become redundant and many lives will be saved thanks to ICIPE’s transmission-blocking intervention.
The research team emphasises the need for further studies to be conducted in order to fully understand how this newly discovered microbe could effectively control malaria.

  As of this August,   more than 90 percent   of safari tour operators have reported losing 75 percent or more of their annual business due to Covid-19. The pandemic has dealt a devastating blow to an industry that was booming just six months earlier. As country after country went into lockdown and emergency quarantine protocols were put in place, lodges had to  put a halt to safaris —not just because customers weren't making new reservations, but also because scheduled safaris were consistently canceled.  Tony Mobile Safari  in Botswana lost more than 150 expected customers.  Mankwe Wildlife Reserve  in South Africa saw every customer cancel.  Mofeg Travel and Tours  in Ghana normally operates seven tours annually; this year, it was  only able to have one .  And tourists aren't the only ones affected by the safari industry's pause. Jarryd du Preez , a safari ranger at South Africa's Phinda Private Game Reserve for tour company &Beyond, says that lodge and safari co

My determination for this coming election, is that we must bring this country together whatever the price and cost, DP William Ruto has said. These were the words of Ruto from a clip aired in  2012. The deputy president shared the clip on Sunday saying that "This was in 2012, 9 yrs ago. Am as persuaded now as was then."   In the clip, Ruto said he is convinced that Kenya must be united. "... those who do not believe that Kenya will be one are in for a shock. I have a lot of energy and I intend to dispense it to get it done," he said.  "We are determined that you will not vote for a person because of the village he is coming from, spelling of his name but what he can do for a nation." Ruto was speaking to Churchill live show in 2012 when he was campaigning. It was not clear what he was alluding to but over the last two weeks, Kenya has seen several politicians who are known foot soldiers of Ruto running to ODM leader Raila Odinga’s office purpor
