Príklady myxomatosis

• The serology and age structure of rabbit populations on sites suggested that some rabbit populations can escape an annual myxomatosis epizootic.

• Rabbits were examined for lesions indicative of active myxomatosis.

• Rabbits infected with viruses from the third group generally did not show serious clinical signs of disease and only one rabbit died of myxomatosis.

• Rather than eradicating the comparatively few survivors of myxomatosis, a rabbit population was allowed to reestablish itself.

• This has implications for the reliability of surveys that rely on anecdotal reports of the prevalence of clinical myxomatosis.

• The initial spread of the virus to non-inoculated rabbits was first indicated by the appearance of myxomatosis in noninoculated rabbits living in the release warrens.

• In each group there were rabbits that did not show any clinical signs of myxomatosis.

• Eight of ten rabbits in this group developed clinical signs of myxomatosis and these developed high levels of antibody by day 18.

• Rabbits affected by myxomatosis were excluded from growth-curve fitting, since this disease causes loss of body condition.

• Two inoculated rabbits did not show definite clinical signs and despite being housed with seven rabbits with severe myxomatosis did not develop disease.

• These trials confirmed that resistance to myxomatosis within wild rabbit populations continues to be substantial and that some rabbits are highly resistant.

• The numbers indicate the order of discovery of cases of myxomatosis from which the released virus was obtained.

• The observation that only a small proportion of rabbits were seen with myxomatosis despite the serological evidence that most became infected was interesting.

• Rabbits on these sites had presumably experienced an epizootic of myxomatosis in the previous year.

• The 57 infected rabbits represented 20.7 % of the 275 rabbits sampled from sites where myxomatosis was found.
