| vector competence of 7 rhipicephalid tick stocks in transmitting 2 theileria parva parasite stocks from kenya and zimbabwe. | the competence of 7 different stocks of rhipicephalus appendiculatus and r. zambeziensis to transmit 2 different stocks of theileria parva was compared by feeding nymphae of each tick stock simultaneously on infected cattle and assessing the infections in the salivary glands of the resultant adult ticks. there were significant differences in the patterns of infection of the 2 stocks (t. parva muguga and t. parva boleni) in the different stocks of ticks, and these differences were shown to be rep ... | 1998 | 9651937 |
| diapause induction in adults of three rhipicephalus appendiculatus stocks. | newly-moulted adults of three rhipicephalus appendiculatus stocks, originating from kenya, zambia and zimbabwe, were kept in different photoperiods (12h:12h, 13h:11h and 14h:10h light:dark). the stock originating from kenya showed almost no behavioural diapause in any of these day lengths, whereas virtually all individuals of the zimbabwean stock entered a behavioural diapause irrespective of day length. adults from the eastern province of zambia, a transition zone between the multivoltine pheno ... | 1999 | 10737730 |
| environment and farm factors associated with exposure to theileria parva infection in cattle under traditional mixed farming system in mbeere district, kenya. | the objective of this study was to investigate the relationship between seroprevalence to theileria parva infection in cattle and potential environmental and farm-level effects in 80 farms under traditional crop-livestock system in mbeere district, kenya. a standardized questionnaire was used to collect the effects characteristics as related to t. parva infection epidemiology. serum samples were collected from 440 cattle of all ages for detection of t. parva antibodies by the enzyme-linked immun ... | 2011 | 20835912 |
