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. ...
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 ...
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 ...
Fecundity and survival of tsetse maintained on immunized rabbits Kaaya Godwin P.; Alemu Patrick
(1982)
Female Glossina morsitans morsitans maintained on rabbits previously immunized with whole tsetse body (WTB), engorged tsetse guts (ETG) or gravid tsetse uteri (GTU) for three successive generations showed no increase in ...
Effect of chronic experimental Trypanosoma congolense infection on the ovaries, pituitary, thyroid and adrenal glands in female goats.
(Uniiversity of Nairobi., 1988-03)
Changes in the ovaries, pituitary, thyroid and adrenal glands in Small East African normally cycling female goats chronically infected with T. congolense are described. Marked fibrosis of the ovaries, a decrease in the ...
The effects of Trypanosoma congolense infection on the testis and epididymis of the goat
(Uniiversity of Nairobi., 1980-03)
Five male non-castrated goats were each injected with 2 ml of blood from an infected goat containing about 0.75 million T. congolense/ml. Two goats died 4 weeks after infection; the remainder and five controls were killed ...
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 ...
