The role of complement in host resistance to infection with Trypanosoma lewisi was studied in normal, C4-deficient, and C3-depleted rats. Complement levels were measured in normal rats throughout the course of infection.

Trypanosoma lewisi II. THE RELATION OF ECTOPARASITES TO THE PREVALENCE OF T. LEWISI IN RATS UNDER NATURAL CONDITIONS. Owing to the fairly constant association in nature of T. lewisi and fleas, it has been assumed that fleas are concerned to a considerable extent in the transmission of the trypanosome from rat to rat. TheCited by: 6. Abstract. Background.

The name is derived from the Greek trypano-(borer) and soma (body) because of their corkscrew-like motion. Most trypanosomes are heteroxenous (requiring more than one obligatory host to complete life cycle) and Class: Kinetoplastea.

In infections with Trypanosoma lewisi in the rat there are three manifestations of resistance against the parasite: (1) the retardation and final inhibition of reproduction of the trypanosomes by about the 10th day; (2) a sudden drop in the number of parasites in the blood between the 9th and 15th days; and (3) the total disappearance of the parasites, which terminates the infection and Cited by: Trypanosoma lewisi is a parasite of Rattus species and other rodents such as mice and kangaroo rats in America.

Abstract. The reproductive activity of Trypanosoma lewisi was strikingly enhanced and sometimes prolonged for 2 days when sublethal doses of adenine were given to rats. The drug was effective when given for 5 or 7 days in the diet and/or intraperitoneally, starting one or two days before infection through two days after by: 5."The Life-History of Trypanosoma Lewisi and Trypanosoma Brucei" is an article from The Journal of Infectious Diseases, Volume 1.
