APHA have announced a new testing site for camelids when the tuberculin test is used for ‘priming’ and is not read. Instead of injecting the tuberculin in the hairless area of the thorax behind the elbow, the base of the neck can be used. This will make testing considerably faster for veterinarians, the owners and the animals.
‘Priming’ is said to boost the TB antibody responses to a subsequent blood test although this assertion has caused considerable controversy. ‘Priming’ can be used before a private blood test, normally Enferplex, or a government funded blood test when a herd is contiguous to a breakdown.
