A polymerase chain reaction-based method for genotyping Giardia duodenalis isolates using a polymorphic region near the 5' end of the small subunit ribosomal (SSU) RNA gene is described. Analysis was performed using Giardia cysts purified directly from feces. Isolates were collected from humans and dogs living in isolated Aboriginal communities where(More)
Delta-aminolaevulinic acid (ALA) is suspected of being responsible for the neuropsychiatric symptoms of acute porphyria. The object of this study was to examine the effects of ALA in vivo on a range of behavioural and physiological functions which are known to be affected in the acute porphyric attack. Aminolaevulinic acid was administered by(More)
The review summarizes the information related to contemporary taxonomy of species within the Giardia genus. The established genotypes of Giardia duodenalis are presented. Data from research carried out on the main aspects of epidemiology, pathogenesis, clinical signs, diagnosis and treatment of giardiasis in humans and animals are analyzed. The major(More)
Hookworm (Ancylostoma duodenale) and other enteric parasites such as Giardia and Hymenolepis are common in Aboriginal communities in northem Australia, and their presence is associated with iron deficiency, anaemia, and failure to thrive. We report the outcome of a sustained, community-based control programme that used regular albendazole in one isolated(More)
delta-Aminolaevulinic acid (ALA) is suspected of being responsible for the neuropsychiatric symptoms of acute porphyria. The object of this study was to examine the effects of continuous administration of ALA in vivo on behaviour known to be affected in acute porphyria. ALA was administered to mice via minipumps implanted subcutaneously. Mean urinary(More)
1 Morphine (1-200 mg/kg s.c.) reduced the incidence and prolonged the latency of priming-induced audiogenic siezures in a dose-dependent manner. 2 This effect was reversed by naloxone (1 and 2 mg/kg) although naloxone was itself inactive. 3 This priming-induces seizure model may be useful in the study of tolerance and physical dependence.
Autosomal recessive spastic ataxia of Charlevoix-Saguenay is a distinct form of hereditary early-onset spastic ataxia caused by cerebellum and spinal cord degeneration. The SACS gene has been demonstrated to be responsible for the disease through worldwide description of different mutations. We report here a computational analysis of a novel SACS gene(More)
Most Web servers hosting biological data limit users to a defined set of search options and output formats that are short of the whole range of options available to users with direct database access. However, to make full use of the wealth of data in the database resource, it is desirable to have an intermediate solution that provides a broad range of(More)
