Susceptibility of different breeds of goats in Kenya to experimental infection withTrypanosoma congolense
(Uniiversity of Nairobi., 1985)
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 ...
Three-stage group screening with errors in observations
(Taylor & Francis, 1985)
This paper examines the performance of three-stage group screening in terms of the expected number of runs and the expected number of incorrect decisions. A few tables are given at the end to provide the reader with a ...
Electroreduction of pyridinium carboxylic acids homarine and trigonelline in acidic solutions
(1984)
Homarine and trigonelline are reduced at the carboxylic acid group at mercury electrodes in acidic solutions. In dc polarography and cyclic voltammetry, reduction yields the hydrated aldehyde, but controlled-potential ...
Quasi-periodic patterns in the East African rainfall records
(1982)
In this study East African rainfall records within the period 1922-80 were
subjected to spectral analysis in order to examine whether the
fluctuations in rainfall during 1922-80 exhibited any periodic or quasi-periodic ...
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.
