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 ...
Achieving sustainable food production in Africa: Roles of pesticides and biological control agents in integrated pest management
(University of Nairobi., 1994-04)
Food production in Africa is declining, while her population is increasing rapidly. Some factors responsible for low food productivity are mentioned; special attention is given to the problem of agricultural pests. The ...
Microorganisms associated with tsetse in nature: Preliminary results on isolation, identification and pathogenicity
(University of Nairobi., 1990-06)
Six genera of bacteria: Serratia, Providencia, Enterobacter, Aeromonas, Cedecea and Bacillus were isolated from field-collected G. pallidipes. Four genera: Serratia, Providencia, Enterobacter and Aeromonas were isolated ...
The use of entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae, as bio-pesticides for tick control
(© International Scholars Journals, 2012-08)
This paper reports promising results on the use of entomopathogenic fungi for tick control. The aqueous formulations of the entomopathogenic fungi, Metarhizium anisopliae isolate RS2 and Beauveria bassiana isolate NM2 ...
Parasitism of Amblyomma variegatum by a Hymenopteran Parasitoid in the Laboratory, and Some Aspects of Its Basic Biology
(University of Nairobi., 1994-06)
Unfed Amblyomma variegatum F. nymphs were experimentally infected in the laboratory with a hymenopteran parasitoid, Ixodiphagus hookeri (Howard). The parasitoid was originally obtained from ticks collected from cattle in ...
Soil ingestion, nutrition and the seasonality of anthrax in herbivores of Etosha National Park
(2013-01)
Anthrax, caused by the bacterium Bacillus anthracis, is a seasonally occurring infectious disease
affecting primarily herbivorous wildlife and livestock. The seasonality of anthrax outbreaks varies among
locations, making ...
Mortalities induced by entomopathogenic fungus
(University of Nairobi., 2011-05)
The objective of this study was to compare the infectivity of Metarhizium anisopliae at a
concentration of 1 × 108 conidia/ml to developmental stages of Amblyomma variegatum,
Rhipicephalus appendiculatus and Rhipicephalus ...
Haemocytes of Glossina—I. Morphological classification and the pattern of change with age of the flies
(University of Nairobi., 1981)
Three morphological classes of haemocytes (prohaemocytes, plasmatocytes and granulocytes) were observed in the haemolymph of Glossina morsitans morsitans and G. pallidipes. In addition to the three types, a category of ...
Characterization of Amblyomma variegatum tick saliva and salivary gland antigens inducing anti-tick immunity in Boran cattle
(University of Nairobi., 1998)
The sequence of proteins synthesized during the feeding of Amblyomma variegatum and humoral resistance acquired by Boran cattle when exposed to A. variegatum infestations were studied. Resistance was induced by repeatedly ...
