Horizontal transmission of Microsporidia MB. Mosquitoes carrying Microsporidia MB are represented with blue shading in pie charts and n = number of independent experiments. (A) No transmission of Microsporidia MB was observed between An. arabiensis larvae reared in the same larval trough but separated by a screen mesh. (B) Horizontal transmission of Microsporidia MB was observed when adults were kept together in cages, and specifically when either infected males or females were housed with uninfected An. arabiensis of the opposite sex. Top row, no transmission was observed between infected and uninfected individuals of the same sex. Bottom left, transmission between Microsporidia MB infected An. arabiensis females and uninfected males was observed in 5 out of 15 cages (33%). Bottom right, out of a total of 16 experiments that had Microsporidia MB infected males and uninfected females and horizontal transmission was confirmed in 10 of these cages (56% transmission).
