The prevalence of Echinococcus granulosus in dogs in the Turkana District of Kenya was 39.4% of 695 examined. Of these, 98 (35.8%) had heavy Echinococcus worm burdens (10(3)-5 X 10(4) ), while 54 (19.7%) and 122 (44.5%) had medium (201-1000) and light (1-200) burdens. The possible sources of these infections are discussed. The prevalence rate differed in(More)
Apis mellifera is an important pollinator but is sometimes associated with adverse effects on natural ecosystems. We surveyed pairs of disturbed and undisturbed sites across three biomes in South East Australia. We used pheromone lures to trap drones, genotyped the drones to infer the number of colonies within flight range and then estimated colony(More)

Six-to-11-day-old calves which received colostrum from cows vaccinated with in vitro culture antigens of Taenia saginata during their last month of pregnancy showed a high level of resistance to a challenge infection with T saginata eggs. Although colostral antibody reduced the numbers of larvae which became established it did not promote destruction of(More)
