  • Resistance of developing honeybee larvae during chronic exposure to dietary nicotine 
    Human, Hannelie; Archer, C. Ruth; Du Rand, Esther Elizabeth; Pirk, Christian Walter Werner; Nicolson, Sue W. (Pretoria : University of Pretoria. Faculty of Natural and Agricultural Sciences. Department of Zoology & Entomology, 2014)
    The effects of pesticides on honeybee larvae are less understood than for adult bees, even though larvae are chronically exposed to pesticide residues that accumulate in comb and food stores in the hive. We investigated ...
  • Simultaneous stressors : interactive effects of an immune challenge and dietary toxin can be detrimental to honeybees 
    Kohler, Angela; Pirk, Christian Walter Werner; Nicolson, Sue W. (Pretoria: University of Pretoria. Faculty of Natural and Agricultural Sciences. Department of Zoology & Entomology, 2012)
    Recent large-scale mortality of honeybee colonies is believed to be caused by multiple interactions between diseases, parasites, pesticide exposure, and other stress factors. To test whether a dual challenge has an additive ...
  • Ultrasonographic evaluation of fetal development in the rat 
    Kirberger, Robert M.; Bester, Elizabeth G. (Pretoria : University of Pretoria. Faculty of Veterinary Science. Dept. of Companion Animal Clinical Studies, 2018)
    The study objectives were to measure gestational sac (GS) diameter and crown-to-rump (CR) length in conscious pregnant rats and to determine the chronological ultrasonographic appearance of heart beat and fetal organogenesis. ...
  • Ultrasonographically determined renal values and comparisons to serum biochemistry renal parameters in aged semi-captive cheetahs (Acinonyx jubatus) 
    Kirberger, Robert M.; Tordiffe, Adrian Stephen Wolferstan (Adrian S.W. Tordiffe University of Pretoria, Faculty of Veterinary Science, Department of Paraclinical Sciences., 2016)
    Cheetahs in captivity have a high prevalence of chronic renal diseases. Abdominal diagnostic ultrasound is a useful diagnostic modality to evaluate the urinary tract and can give an immediate indication of renal status but ...
