Immunization of cattle against East Coast fever using Theileria parva (Marikebuni) and relaxation of tick control in North Rift, Kenya
(Department of Chemistry, 2001)A total of 90 animals was immunized against East Coast fever (ECF) using Theileria parva (Marikebuni) stock on three large-scale farms in Kiminini Division, Trans-Nzoia District, North Rift, Kenya. Another 90 cattle served ... -
Immunization of cattle with Ra86 impedes Rhipicephalus appendiculatus nymphal-to-adult molting
(© 2012 Elsevier GmbHSchool of biological sciences, 2012)Commercial vaccines based on the tick gut protein Bm86 have been successful in controlling the onehost tick Rhipicephalus (Boophilus) microplus and provide heterologous protection against certain other non-target ixodid ... -
Immunization of rabbits with a midgut extract of the human body louse Pediculus humanus humanus: the effect of induced resistance on the louse population
(Department of Biochemistry, 1994)Resistance to human body lice, Pediculus humanus humanus L, induced by feeding on rabbits immunized with an extract of louse gut was studied. The mortality of lice fed on immunized rabbits was 73%, significantly higher ... -
Immunization of rabbits with faecal extract of Pediculus humanus, the human body louse: effects on louse development and reproduction
(Department of Biochemistry, 1997)Immunization of rabbits with a faecal extract of the human body louse (Pediculus humanus) induced a high titre of specific IgG. The mean weight of blood taken by females fed on the immunized rabbits was significantly lower ... -
Immunological Responses of Mice After Treatment with Ocimum Americanum Hexane and Bridelia Micrantha Water Plant Extracts
(2014)Background-The T helper 1 (TH1) and TH2 dichotomy was first shown in murine CD4+ lymphocytes clones and these cells could be differentiated in terms of the cytokines they secrete. The TH1 subsets produce interleukin 2 ... -
