Quality over quantity: unraveling the contributions to cytoplasmic incompatibility caused by two coinfecting Cardinium symbiontsM. R. Doremus, C. M. Stouthamer, S. E. Kelly, S. Schmitz-Esser and M. S. Hunter, Heredity, 2022.![]() Cytoplasmic incompatibility (CI) is a common form of reproductive sabotage caused by maternally inherited bacterial symbionts of arthropods. CI is a two-step manipulation: first, the symbiont modifies sperm in male hosts which results in the death of fertilized, uninfected ...

Wolbachia reduces virus infection in a natural population of DrosophilaR. Cogni, S. D. Ding, A. C. Pimentel, J. P. Day and F. M. Jiggins, Communications Biology, 4:1327. 2021.![]() Wolbachia is a maternally transmitted bacterial symbiont that is estimated to infect approximately half of arthropod species. In the laboratory it can increase the resistance of insects to viral infection, but its effect on viruses in nature is unknown. Here we report that in a ...

Microsporidia MB is found predominantly associated with Anopheles gambiae s.s and Anopheles coluzzii in GhanaJ. Akorli, E. A. Akorli, S. N. A. Tetteh, G. K. Amlalo, M. Opoku, R. Pwalia, M. Adimazoya, D. Atibilla, S. Pi-Bansa, J. Chabi and S. K. Dadzie, Scientific Reports, 11:5. 2021.![]() A vertically transmitted microsporidian, Microsporidia MB, with the ability to disrupt Plasmodium development was reported in Anopheles arabiensis from Kenya, East Africa. To demonstrate its range of incidence, archived DNA samples from 7575 Anopheles mosquitoes collected from ...

Breakthrough in non-GMO malaria controlC. Robinson and J. Matthews, GM Watch, 2021.![]() A just-published study carried out in a high-security lab claims to show that a CRISPR gene drive (a way of forcing a heritable genetic modification through a whole species or population) can crash populations of malaria-spreading mosquitoes. But why crash mosquito populations ... Keywords: gene drive synthetic, genetic biocontrol, genetic incompatibilities, mosquito, paratransgenesis, public health, review, symbiont, wolbachia |

Horizontal Transmission of the Symbiont Microsporidia MB in Anopheles arabiensisG. Nattoh, T. Maina, E. E. Makhulu, L. Mbaisi, E. Mararo, F. G. Otieno, T. Bukhari, T. O. Onchuru, E. Teal, J. Paredes, J. L. Bargul, D. M. Mburu, E. A. Onyango, G. Magoma, S. P. Sinkins and J. K. Herren, Frontiers in Microbiology, 12. 2021.![]() The recently discovered Anopheles symbiont, Microsporidia MB, has a strong malaria transmission-blocking phenotype in Anopheles arabiensis, the predominant Anopheles gambiae species complex member in many active transmission areas in eastern Africa. The ability of Microsporidia ... Keywords: gene drive synthetic, genetic biocontrol, genetic incompatibilities, mosquito, paratransgenesis, public health, review, symbiont, wolbachia |
