East Coast Fever Immunisation Trials in Uganda: Field Exposure of Zebu Cattle Immunized with Three Isolates of Theileria Parva
(Tropical Animal Health and Production, 1977)Zebu cattle were immunised against East Coast fever (ECF) using three isolates ofTheileria parva inoculated as cryopreserved stabilates of infective particles harvested fromRhipicephalus appendiculatus. These isolates ... -
Dose Response Relationship of Haemophilus pleuropneumoniae Aerosols in Pigs
(Canadian Journal of comparative medicine, 1983)The virulence of Haemophilus pleuropneumoniae was quantitated for ten and 12 week old pigs following aerosol exposure. The volume and concentration of culture aerosolized, the estimated numbers of organisms inhaled by the ... -
Production of Fumonisins by Fusarium moniliforme and Fusarium proliferatum Isolates Associated with Equine Leukoencephalomalacia and a Pulmonary Edema Syndrome in Swine
(Applied and Environmental Microbiology, 1990)During the 1989 corn harvest season, the National Veterinary Services Laboratories received numerous reports of outbreaks of equine leukoencephalomalacia (ELEM) and a porcine pulmonary edema syndrome (PPE). The PPE ... -
Anaplasmosis in Uganda. II. Prevalence of Bovine Anaplasmosis
(Scandinavian Journal of Immunology, 1992)The prevalence of bovine anaplasmosis was studied in 320 Zebu cattle randomly selected from three regions of Uganda (central, south-western and north-western) using DOT-ELISA, Western immunoblotting. Rapid Card Agglutination ... -
Characterization of the coffee berry disease pathogen, Colletotrichum kahawae sp. nov.
(Mycological Research, 1993)A range of Colletotrichum isolates from coffee, including the coffee berry disease (CBD) pathogen, and representative isolates of C. gloeosporioides from some other tropical crops are compared. Isolates of the CBD pathogen ... -
Wind-Tunnel Studies on the Collection of Airborne Spray Droplets by Flying Locusts
(International Journal of Tropical Insect Science, 1994)In view of the present environmental awareness, the reduction of spray wastage, which in turn lessens environmental contamination, can be achieved by reducing spray volumes and improvement on spray efficiency through the ... -
Elephants, Selective Logging and Forest Regeneration in the Kibale Forest, Uganda
(Journal of Tropical Ecology, 1996)The Kibale Forest, western Uganda, is the only site where studies have compared the impact of elephants on rainforest regeneration in logged and unlogged control areas. Elephants used heavily logged areas more than lightly ... -
Mangabey (Cercocebus albigena) Ranging Patterns in Relation to Fruit Availability and the Risk of Parasite Infection in Kibale National Park, Uganda
(American Journal of Primatology, 1997)Two opposing hypotheses concerning determinants of mangabey (Cercocebus albigena) ranging patterns have been advocated. One hypothesis suggests that ranging patterns of mangabeys are largely a response to fruit availability, ... -
Changes in leaf lamina shape and size during banana shoot development
(Journal of Applied Biosciences, 1997)Bananas and plantains are grown as perennial crops, producing consecutive generations from suckers, which develop on the main plant. Sucker development consists of distinct physiological stages: peeper (small sucker appearing ... -
Interaction of Ht and Partial Resistance to Exserohilum turcicum in Maize
(Plant disease, 1997)Components of northern leaf blight resistance in maize due to race-specific resistance controlled by the Ht gene, partial resistance derived from inbred H99, and a combination of the two kinds of resistance, were studied ... -
Increasing Conversion in Membrane Filtration Systems using a Desupersaturation Unit to Prevent Scaling
(Desalination, 1998)A desupersaturation unit (DU), placed between the stages of either RO or NF systems is aimed at reducing the degree of supersaturation in the concentrate stream thus preventing membrane scaling in the last stage of a ... -
Complementarity and the Use of Indicator Groups for Reserve Selection in Uganda
(Nature, 1998)A major obstacle to conserving tropical biodiversity is the lack of information as to where efforts should be concentrated. One potential solution is to focus on readily assessed indicator groups, whose distribution predicts ... -
Assessing Fern Diversity: relative species richness and its environmental correlates in Uganda
(Biodiversity & Conservation, 1998)Techniques for the rapid quantification of tropical biodiversity are of critical importance in deciding where to invest scarce conservation resources. Here we describe a simple survey method for assessing species-level ... -
Population dynamics of ticks on indigenous cattle in a pastoral dry to semi-arid rangeland zone of Uganda
(Experimental & applied acarology, 1999)Studies on seasonality and population dynamics of ticks on indigenous cattle and their crosses (calves) were carried out in Buruli Ranching Scheme, Nabiswera, Luwero district of Uganda on three treatment groups of animals: ... -
Pests and diseases on cowpea in Uganda: Experiences from a diagnostic survey
(African Crop Science Journal, 1999)A diagnostic survey (DS) using a questionnaire covering 525 farm households was conducted in 1993/94 to determine the status of cowpea (Vigna unguiculata L. Walp) and its production constraints in Uganda. Subsequent ... -
Regeneration of an afromontane forest Following agricultural encroachment in Southwestern Uganda
(Israel Journal Of Plant Sciences, 2000)A study of the regeneration of an Afromontane forest was carried out in Mgahinga Gorilla National Park (MGNP), southwestern Uganda, following agricultural encroachment in the last 50 years. The landscape was changed by ... -
Comparison of damage levels caused by Radopholus similis and Helicotylenchus multicinctus on bananas in Uganda
(Annals of Applied Biology, 2000)Field surveys were done in 1997 and 1998 in Masaka district, Uganda, an area which is experiencing a decline in banana production, to assess level of damage caused by nematodes Radopholus similis and Helicotylenchus ... -
Spatial Distribution of Nematode Population Densities and Nematode Damage in Roots of Three Banana Cultivars in Uganda
(Nematropica, 2000)The spatial distribution of nematode populations and damage in roots of Nabusa ( Musa AAAgroup ‘Matooke’), Pisang Awak ( Musa ABB) and Sukali Ndizi ( Musa AB) three banana cultivars widely grown in Uganda, was ... -
The Effect of Oral Administration of Polyethylene Glycol on Faecal Helminth Egg Counts in Pregnant Goats Grazed on Browse Containing Condensed Tannins
(Tropical Animal Health and Production, 2000)Thirty yearling F1 Anglo-Nubian 6 Mubende goats, averaging 21+0.45 kg, kept on free-range feeding in the Ankole range land, Uganda, were screened for health and nutritional status, effectively treated against helminth ... -
Primate Community Dynamics in Old Growth Forest over 23.5 Years at Ngogo, Kibale National Park, Uganda: Implications for Conservation and Census Methods
(International Journal of Primatology, 2000)Few data exist regarding long-term changes in primate populations in old-growth, tropical forests. In the absence of this information, it is unclear how to assess population trends efficiently and economically. We addressed ...
