[Characteristics of digestion of blood of different animals by the flea Xenopsylla cheopis].
Under experimental conditions fleas X. cheopis engorged and assimilated blood of 4 species of rodents, man, pigeon and two species of reptiles. Histological investigations have shown that the structure of food clot, destruction rate of blood  cells and general duration of digestion are changed considerably depending on the host's blood. In females the digestion of white mice blood to haematin at 23-24 degrees lasted not over 12 hours, the digestion of blood of hamsters and man - 12 to 20 hours, of guinea pigs and reptiles - 18 to 25 hours and of white rats and pigeons - from 20 to 30 hours. In males the digestion carries out somewhat slower. The above differences in blood digestion can apparently create unequal conditions for pathogenic microbes in the intestine of fleas that affects the preservation and reproduction of the agent in the organisms of these carriers.
