Traduction de «infection à mycoplasma sans précision » (Français → Anglais) :

if a second test of an appropriate type confirms the presence of infection by Salmonella pullorum, Salmonella gallinarum, Salmonella arizonae, Mycoplasma gallisepticum or Mycoplasma meleagridis;

Tests for detecting Mycoplasma gallisepticum or Mycoplasma meleagridis must be performed on a representative sample in order to allow continuous surveillance of the infection during rearing and laying, i.e. just before the start of laying and every three months thereafter.

In evaluating a test it is extremely important to be sure that the samples from the diseased animals really had BSE and that the samples from the healthy animals were really not infected. Otherwise the evaluation is not accurate.

For example, in Vancouver, a state of medical emergency resulted from a rapid increase in the number of HIV cases among users of injectable drugs, more specifically in Vancouver East, where the prevalence rate of such cases went from 20 per cent in 1997 to 35 per cent in 1998, that is in less than one year.

- a census be made of all categories of animals of susceptible species and that, in respect of each of these categories, the number of animals already dead, infected or liable to be infected or contaminated be recorded; the census must be kept up to date to take account of animals born or dying during the period of suspicion; the information in the census must be produced on request and may be checked at each visit;

The paper also makes a useful summary of the state of knowledge in the key areas. The following is a list of areas considered by the group as worthy of research : - research aimed at establishing whether or not BSE has been transmitted to man; - working on the hypothesis that BSE may be transmissible to man, a number of suggestions are put forward aimed at establishing a risk assessment such as work on determining whether multiple dosing is cumulative and an estimation of the utilisation of offal in different human food products prior to the ban and the consumption of those products by individual age groups and socio-economic criteria; - is there infectivity in BSE-in ...[+++]fected cattle derived products other than SBO (Specified Bovine Offal) ?; - further research to establish the precise reason or route for maternal transmission of BSE in some cases; - establish if it is possible that BSE originated as a (rare) spontaneous event in cattle and that the BSE agent is different from the scrapie agent; - can BSE be transmitted orally to pigs ?; - research into the development of diagnostic techniques for BSE and CJD; - establish the efficiency of BSE inactivation procedures used in the food and pharmaceutical industry; - certain areas are suggested for research into developing therapeutic treatment for victims of the CJD disease and also into developing a test which would indicate those people susceptible to the disease; - predictive research is also proposed as it has been shown that CJD occurs rarely in individuals with certain genes.
