Fig. 3.

Parasitaemia of single infections with a specific Plasmodium (red) or Haemoproteus parasite lineage (grey) from collard Sand martins (Riparia riparia). Filled circles are medians (± 25/75 percentiles if n > 2), open circles give lineages with single observations. Black vertical lines indicate genus specific median parasitaemia. Median parasitaemia was genus specific and usually low, which is typical for chronic infections, except in three hosts (indicated with stars) infected with SYBOR21, RIPRIP01 and RIPRIP03 and maximum parasitaemia between 6.5 and 16.2%
