Prospects of using tick parasitoids (Insecta) for tick management in Africa
(University of Nairobi., 1997)
Since the first report of tick parasitoids by Howard (1907), sevens pecies belonging to the genus Ixodiphagus have been described. Apart from a few parasitoid releases in the USA and Europe in the first third of the century, ...
Acaricidal activity of Margaritaria discoidea (Euphorbiaceae) plant extracts against the ticks Rhipicephalus appendiculatus and Amblyomma variegatum (Ixodidae)
(Uniiversity of Nairobi., 1995)
A water soluble extract of M. discoidea, an African indigenous plant induced high mortalities in nymphs of both Rhipicephalus appendiculatus, and Amblyomma variegatum and in adult R. appendiculatus, but not in adult A. ...

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, ...
Prevalence and antimicrobial resistance pattern of Salmonella in animal feed produced in Namibia
(© Istituto G. Caporale 2012, 2012-06)
The occurrence of Salmonella is a global challenge in the public health and food production sectors. Our study investigated the prevalence, serovar and antimicrobial susceptibility of strains of Salmonella serovars isolated ...
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 ...
Repellence of the tickRhipicephalus appendiculatus by the grassMelinis minutiflora
(Uniiversity of Nairobi., 1995-11)
In a study to develop anti-tick pastures, the climbing behaviour ofRhipicephalus appendiculatus onMelinis minutiflora (molasses grass) was investigated. Experiments were done with cut green stems of grass, grass dried in ...
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 ...
