Virus strikes at AI facility
IBR hits the Tully Test Station for second time
The IBR virus has struck the Tully Test Station for the second time in less than 12 months.
It has been confirmed that two bulls at the facility tested positive for the disease last week, just four months after the station reopened following a serious IBR outbreak.
The infected bulls were in adjoining pens at the station. Tests on 10 more animals from the same shed proved negative.
Although Tully management are adamant that a full IBR outbreak has been prevented, the fact that bulls at the station have once again picked up the virus will cause grave concern.
A major outbreak of IBR closed Tully last April and the unit did not reopen until November. The current crop of bulls is the first to be taken into the facility since then.
Doreen Corridan, who worked with the ICBF and the breed societies in drawing up stringent bio-security procedures for Tully in the wake of last year's outbreak, admitted that the detection of two more cases at the station was a serious disappointment.
However, Ms Corridan maintained that the early detection of the virus and the immediate isolation of the infected bulls had prevented a more serious situation from developing. "The two bulls found with IBR were positive in the nasal swab tests but clear in the bloods, which suggests that the infection was caught quiet early," Ms Corridan claimed.
She said the source of the infection had not been identified. It is possible that one of the bulls was a latent carrier, though this is not thought likely. The disease could have been carried on the air or brought into the station by wildlife.
