Complement in experimental Trypanosoma lewisi infection of rats.
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. A drastic reduction of total complement and C4 hemolytic activities occurred, and C3 levels measured immunochemically were decreased. Although total complement and C4 levels we...
متن کاملEffect of splenectomy on Trypanosoma lewisi infection in young rats.
The effect of splenectomy on animals infected with Trypanosoma lewisi is unclear, and previous reports are inconclusive or conflictive. We splenectomized rats of different ages after they had been infected with T. lewisi. Female Sprague-Dawley rats, Hemobartonella-free, were assigned to four groups according to weight: 80, 108, 140, and 170 g. Each group had splenectomized, sham-operated, and n...
متن کاملTrypanosoma lewisi infection in the rat: effect of adenine.
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 infection. Peak parasitemia was also enhanced. In terms of host immunity, daily suble...
متن کاملEfficacy of repeated doses of diminazene aceturate (Dinazene®) in the treatment of experimental Trypanosoma brucei infection of Albino rats
The efficacy of repeated doses of Dinazene® in Albino rats experimentally infected with Trypanosoma brucei (Gboko strain) was investigated. A total of 30 adult female Albino rats weighing 130-190 g were used for the study. They were assigned to six groups (groups A-F) of five rats each. Groups A-D were infected intraperitoneally with 1.0 × 106 trypanosomes in 400 μL of PBS diluted blood while g...
متن کاملEffects of lysozyme on Trypanosoma lewisi.
Daily lysozyme (hen egg) injections, beginning on day 6 of Trypanosoma lewisi infections in rats, significantly reduced the number of circulating trypanosomes. The effect was dose dependent. Maximum reduction (50%) occurred 24 hours after one treatment of 80 mg was given intraperitoneally (I.P.). The same dose of lysozyme was more effective when divided equally into two injections per day. Cont...
