This offers the possibility of amending routine surveillance sampling to include cerebellum taken through the foramen magnum, as is currently required for sheep, thereby enhancing the discriminatory potential of the confirmatory testing.

Routine slaughter surveillance samples were inoculated using MGIT and 4 solid media.
After this survey revealed ongoing contamination of the unit, a concerted effort for terminal cleaning of the Unit was performed in October 2011, and implementation of monthly routine surveillance, including sampling both before and after hospital cleaning.
For this reason, in routine surveillance programs, additional sampling methods could be necessary to detect AIVs on birds' bodies.
Stool specimens from a subset of patients from routine surveillance during 2007 2009 (1,614 samples total) were available for further studies.
The survey was part of routine surveillance making the actual sample size (32,665) equal to the maximum number of surveillance households that the HDSS surveillance teams could survey in that two month period.
Despite this, the ongoing proficiency testing by the SNRL showed a high level of accuracy of the susceptibility testing of the samples from routine surveillance.
With the introduced scoring system, the information contained in the AMD can be used to optimize the selection of farms in the sample for routine surveillance.
Of the samples collected during routine surveillance, 2,688 (42.6%) were positive for respiratory viruses by isolation; of those 1,583 (25.1%) were positive for influenza A virus, 609 (9.7%) for influenza B virus, 115 (1.8%) for an adenovirus and 202 (3.2%) for parainfluenza 1, 2 or 3 viruses (Table 2).
