Effects of bacteria, antibacterial compounds and trypanosomes on tsetse reproduction and longevity
(University of Nairobi., 1987-04)
Haemocoelic injections of live Escherichia coli and oral administration of three tetracycline compounds, namely Reverin, Maxitet and Terramycin to female Glossina morsilans morsitans prior to their first larviposition, ...
Comparative study of hemocytes and associated cells of some medically important dipterans
(University of Nairobi., 1982-09)
The aim of this work is to study, characterize, and compare different morphological types of hemocytes of Glossina austeni, G. morsitans, Calliphora erythrocephala, Stomoxys calcitrans, Lucilia sericata, Aedes aegypti, and ...
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, ...
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. ...
Characteristics of erythroid colonies formed by bovine marrow progenitor cells in methyl cellulose cultures
(University of Nairobi., 1982-03)
Bovine erythroid colonies containing eight to 100 erythroid cells were successfully cultured in methyl cellulose. The colonies required four to five days to mature and a direct linear relationship (r = 0.99) between the ...
A review of the progress made in recent years on research and understanding of immunity in insect vectors of human and animal diseases
(University of Nairobi., 1989-12)
Different modes of immune reactions of insect vectors of human and animal diseases to nematode and protozoan parasites, fungi, bacteria, viruses and to other biological materials e.g. xenografts are discussed in this paper. ...
