Why Do Some Primate Malarias Relapse?
Relapse may have evolved in malaria as a mechanism to avoid suppression by more virulent species in mixed infections, thereby increasing transmission opportunities. Later evolution of long latency in Plasmodium vivax was a necessary adaptation as early hominins moved to colder areas with shorter mosquito breeding seasons. Genetic diversity was maintained through heterologous hypnozoite activation.
متن کاملPrimate malarias: Diversity, distribution and insights for zoonotic Plasmodium
Protozoans within the genus Plasmodium are well-known as the causative agents of malaria in humans. Numerous Plasmodium species parasites also infect a wide range of non-human primate hosts in tropical and sub-tropical regions worldwide. Studying this diversity can provide critical insight into our understanding of human malarias, as several human malaria species are a result of host switches f...
متن کاملMalaria's primate links
But the article also quoted the view of the policy director of the Soil Association, Lord Melchett, that the FSA had " jumped the gun " by " preempting " another review of the same topic being conducted for the European Union. Alongside a tabular presentation of the FSA's facts and figures, there were short separate pieces on wider aspects of the subject. One quoted an employee of an organic fo...
متن کاملAccelerated Diversification of Nonhuman Primate Malarias in Southeast Asia: Adaptive Radiation or Geographic Speciation?
Although parasitic organisms are found worldwide, the relative importance of host specificity and geographic isolation for parasite speciation has been explored in only a few systems. Here, we study Plasmodium parasites known to infect Asian nonhuman primates, a monophyletic group that includes the lineage leading to the human parasite Plasmodium vivax and several species used as laboratory mod...
متن کاملThe Historical Ecology of Human and Wild Primate Malarias in the New World
The origin and subsequent proliferation of malarias capable of infecting humans in South America remain unclear, particularly with respect to the role of Neotropical monkeys in the infectious chain. The evidence to date will be reviewed for Pre-Columbian human malaria, introduction with colonization, zoonotic transfer from cebid monkeys, and anthroponotic transfer to monkeys. Cultural behaviors...
