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. ...
Prevalence of ixodid ticks and trypanosomosis in camels in southern rangelands of Ethiopia
(University of Nairobi., 2004)
The prevalence of ixodid ticks and trypanosomosis of camels was studied in the semi-arid rangelands of southern Ethiopia between 1995 and 1996. A total of 24077 ticks were collected from 510 camels aged between 6 months ...
Bovine erythrocytic, granulocytic and macrophage colony formation in culture. A preliminary report
(University of Naitrobi, 1978-07)
Bovine erythrocytic colonies containing up to 300 cells each were produced by using a plasma clot technique with five percent CO2 at 37 degrees C. with high humidity and 2.5 units of sheep step III erythropoietin per ...
Trypanosome-induced ovarian dysfunction. Evidence of higher residual fertility in trypanotolerant small East African goats
(University of Nairobi., 1988-09)
Changes in the length of oestrous cycles, plasma progesterone and oestradiol-17 beta levels were monitored for 6 months in Trypanosoma congolense-infected normocyclic small East African goats obtained from three tsetse-endemic ...
Bovine granulocyte/macrophage and erythroid colony culture: characteristics of the colonies and the assay systems
(University of Nairobi., 1979-10)
Bovine bone marrow granulocyte/macrophage colonies were cultured in vitro in methyl cellulose and in plasma clots using bovine endotoxin-stimulated serum as a source of colony stimulating activity. The endotoxin-stimulated ...
The humoral defense system in tsetse: differences in response due to age, sex and antigen types.
(University of Nairobi., 1988)
Inoculation of live Escherichia coli into tsetse flies, Glossina morsitans morsitans, stimulated a higher antibacterial immune response in females than in males. It increased with age in females from emergence to approximately ...
Glossina morsitans morsitans: mortalities caused in adults by experimental infection with entomopathogenic fungi
(University of Nairobi., 1989-03)
Various strains of the entomopathogenic fungi: Beauveria bassiana, Metarhizium anisopliae, Paecilomyces fumosoroseus and P. farinosus were found to be pathogenic for adult tsetse, Glossina morsitans morsitans but B. bassiana ...
Comparative trypanotolerance of the small east African breed of goats from different localities to Trypanosoma congolense infection
(University of Nairobi., 1989-05)
Differences in susceptibility of the Small East African breed of goats to an experimental Trypanosoma congolense infection were investigated. The goats were obtained from different areas of East Africa, Morogoro and Arusha ...
