Insect immunity: Induction of cecropin and attacin-like antibacterial factors in the haemolymph of Glossina morsitans morsitans
(University of Nairobi., 1987)
Injections of live Escherichia coli into adult tsetse flies, Glossina morsitans morsitans induced an antibacterial activity in the haemolymph after a lag period of 6–18 hr. Peak activity occurred after 24–72 hr with a dose ...
Susceptibility of different breeds of goats in Kenya to experimental infection with Trypanosoma congolense
(University of Nairobi., 1985-08)
To assess whether there was any evidence of genetic resistance to African trypanosomiasis, five breeds of goat (East African, Galla, and crossbreds between East African and Galla, Nubian or Toggenburg) were experimentally ...
Inhibition of leukopoiesis by sera from Trypanosoma congolense infected calves: partial characterization of the inhibitory factor
(University of Nairobi., 1980-06)
Sera collected from calves infected with Trypanosoma congolense inhibited bovine granulocyte/macrophage colony formation in vitro, but not erythroid colony formation. The inhibitor was found to be TCA precipitable in nature ...
The kinetics of haemopoietic differentiation assessed by in vitro bone marrow culture in endotoxin-treated and in anaemic calves
(University of Nairobi., 1980-07)
Marrow aspirates from calves injected with Pseudomonas aeruginosa endotoxin showed an increased number of granulocyte/macrophage progenitor cells, and a reduced number of erythroid progenitor cells. On the other hand, ...
A comparative study of anthraquinones in rhizomes of Kniphofia species
(University of Nairobi, 1988-01-14)
The anthraquinone content of eight kniphofia species was compared using reversed phase HPLC method coupled with a photodiode array detector.
Depression of ovarian function and plasma progesterone and estradiol-17 beta in female goats chronically infected with Trypanosoma congolense
(University of Nairobi., 1988-04)
Adult normocyclic female goats experimentally infected with Trypanosoma congolense developed irregular and shorter estrous cycles before complete cessation at the fourth cycle post-infection. This was followed within a ...
Mortality in adult tsetse, Glossina morsitans morsitans, caused by entomopathogenic bacteria
(University of Nairobi., 1989-07)
Mortality in adult tsetse, Glossina morsitans morsitans, caused by Pseudomonas aeruginosa, Serratia marcescens, Bacillus sphaericus, Bacillus cereus, Bacillus thuringiensis H-14, B. thuringiensis 1, B. thuringiensis 5, B. ...
