title: Malaria transmission, sex ratio and erythrocytes with two gametocytes.
abstract: Transmission of haemospororin parasites (phylum Apicomplexa) needs the fertilization of at least one female by one male gamete within the bloodmeal of a suitable vector. Male and female gamete precursors (gametocytes) in Plasmodium and Haemoproteus parasites are normally alone inside the erythrocytes of the vertebrate host, but they also occur in male-female pairs in single erythrocytes. These paired gametocytes could enhance transmission success by facilitating the encounter between the female and male gametes when inside the midgut of the vector. Further study of these particular infections could provide new insights into the biology of and control strategies for haemospororin parasites.
