The C2 pedicle screw is more biomechanically stable and provides patients with increased postoperative range of motion in comparison to other methods of C2 fixation. However, as a result of the proximity of the C2 pedicle to the transverse foramen, there is a considerable risk of intraoperative morbidity due to vertebral artery injury laterally or vertebral canal breach medially. Other than the...

Following on from our studies on the potential use of tannins to control intestinal parasites in small ruminants we recently conducted two further trials to investigate the effect of a wattle tannin oral drench (WT), or supplementation of the diet with acacia (AMS), on faecal egg counts (FEC) and worm burdens of growing tropical Black Head Persian (BHP) sheep with an experimental intestinal nem...

Internet worms continue to plague the Internet infrastructure with wider and deeper impact since the Morris Worm in early 1988. It has been further shown that better-engineered worms like Warhol worms and Flash worms could spread across the Internet in minutes or even tens of seconds rather than hours. Such virulent spreading invalidates any manual counter-measures and poses an extremely seriou...

OBJECTIVE To investigate correlates of resistance to GI nematode infection in Nigerian West African dwarf (WAD) sheep. METHODS Thirty three sheep were randomly assigned to two groups, A (n=27) which were used for experimental infections, and B (n=6) which served as uninfected control. Each infected animal received weekly escalating infections with infective larvae (60%Haemonchus contortus (H....

BACKGROUND Degenerative lumbosacral stenosis is a common problem in large breed dogs. For severe degenerative lumbosacral stenosis, conservative treatment is often not effective and surgical intervention remains as the last treatment option. The objective of this retrospective study was to assess the middle to long term outcome of treatment of severe degenerative lumbosacral stenosis with pedic...

Allergic-type immune responses, particularly immunoglobulin E (IgE), correlate with protective immunity in human schistosomiasis. To better understand the mechanisms of parasite elimination we examined the immune correlates of protection in baboons (Papio cynocephalus anubis), which are natural hosts for Schistosoma mansoni and also develop allergic-type immunity with infection. In one experime...
