Cattle can become infectious long before they exhibit any obvious clinical signs or lesions typical of bTB, even with the most careful vet inspection (<a href=\"#ref\">de la Rua-Domenech, 2006<\/a>). However, they can spread disease around 87 days after infection occurs (<a href=\"#ref\">Neill et al., 1991<\/a>). Entry is usually by inhalation (especially if housed) or ingestion (when wildlife is the source of infection). Once in a herd, infection probably spreads from cow to cow by inhalation (<a href=\"#ref\">Costello et al., 1998<\/a>), and transmission from cows to calves may occur via the milk or colostrum (<a href=\"#ref\">Evangelista and De Anda, 1996<\/a>).<\/strong>\n<\/div>\n<div class=\"one_third last\">\n<p style=\"text-align: left;\"><a class=\"button medium alternative-1\" title=\"Clinical signs of bTB?\" href=\"#clinical_signs\">Clinical signs of bTB?<\/a><br \/>\n<a class=\"button medium alternative-1\" title=\"Control and Prevention\" href=\"#control_prevention\">Control and Prevention<\/a><br \/>\n<a class=\"button medium alternative-1\" title=\"Pre- and post-movement testing\" href=\"#pre-movement\">Pre- and post-movement testing<\/a><br \/>\n<a class=\"button medium alternative-1\" title=\"bTB Spread from Cattle\" href=\"#spread_cattle\">bTB Spread from Cattle<\/a><br \/>\n<a class=\"button medium alternative-1\" title=\"bTB Spread from Wildlife\" href=\"#spread_wildlife\">bTB Spread from Wildlife<\/a><br \/>\n<a class=\"button medium alternative-1\" title=\"What are the treatment options?\" href=\"#treatment\">Treatment Options<\/a><br \/>\n<a class=\"button medium alternative-1\" title=\"Good Practice Based on Current Knowledge\" href=\"#good_practice\">Good Practice<\/a>\n<\/div>\n<div class=\"clear\"><\/div>\n<\/p>\n<p style=\"text-align: left;\">\n<div class=\"hr hr3\" style='margin:20px 0px 20px 0px !important;'><\/div>\n<\/p>\n<p style=\"text-align: left;\">While once TB was the most prevalent infectious disease of cattle and swine in the United States, it has now been nearly eradicated from livestock in the US through a cooperative state-federal program.

There is evidence that more intensive dairy farms have a higher risk of infection (<a href=\"#ref\">Griffin et al., 1993<\/a>).

This can either be a single intradermal test (SIT) or a single intradermal comparative cervical test (SICCT). The SICCT is a separate but simultaneous injection into the skin on the neck of the cow of both bovine and avian tuberculin next to each other. Some cows may be exposed to other mycobacterium species (that are not <em>M. bovis<\/em>), so a comparative test can discriminate between these cows and should help to minimize false positives. With both skin tests, the vet must revisit the farm 3 days later to measure any localized swelling caused by an immune response. The presence and size of this swelling will determine if the cow is a reactor, inconclusive reactor (IR) or TB free.<\/p>\n<p>The type of skin test (SIT or SICCT) selected depends on the <span class=\"tooltips\"><a href=\"#\" rel=\"tooltip\" title=\"Proportion of a population to have a specific disease\">prevalence<\/a><\/span> of TB, and on the <span class=\"tooltips\"><a href=\"#\" rel=\"tooltip\" title=\"Proportion of a population to have a specific disease\">prevalence<\/a><\/span> of other environmental mycobacteria. In the USA, Canada and New Zealand the <span class=\"tooltips\"><a href=\"#\" rel=\"tooltip\" title=\"The base of the tail\">caudal fold<\/a><\/span>\u00a0SIT is the primary test for routine TB screening. In the UK and Ireland, the SICCT test is used (<a href=\"#ref\">de la Rua-Domenech et al., 2006<\/a>).<\/p>\n<p>The IFN-gamma test is often used as an ancillary (extra) test to the skin test and involves a blood sample being taken from the animal, and this is immediately transported to the lab where it is incubated in the presence of <em>M. bovis<\/em> antigens. The level of IFN \u2013gamma detected in these samples determines if the animal has been previously exposed to <em>M. bovis<\/em> antigens. The advantages of this test over the skin test are only one visit is needed to the farm, it can detect infection 1-5 weeks after infection unlike 3-6 weeks for the skin tests, and repeat tests can be carried out immediately after, instead of a 60 day break for the skin tests. The disadvantages of the IFN-gamma test include a lower specificity (produces more false positives) and the challenge of keeping the blood samples between 10 and 26\u00b0C until testing. Also a small number of cattle that react to the skin test are undetected in the IFN-gamma test (<a href=\"#ref\">Pollock et al., 2005<\/a>).<\/p>\n<p>In the UK, animals which react to the skin test (Reactors) are compulsorily slaughtered, and restrictions are put in place (a TB2 Restriction Notice is issued to the farm) so that animals may not be moved on or off the affected farm (except direct to slaughter under license) until further tests show that the herd is clear. After a reactor is confirmed by post mortem and\/or culture a\u00a0herd must have two clear tests 60 days apart before restrictions are lifted. Some cows that react slightly but not enough to be a Reactor are deemed \u2018Inconclusive Reactors\u2019 (IR). All Reactors and IRs must be isolated from the rest of the herd immediately. Milk from reactors is unfit for human consumption.<\/p>\n<p>What happens next depends on whether or not confirmed reactors have been identified in the herd, and if the herd has had a TB breakdown in the past 3 years. If not and no other reactors have been identified, the IRs will be put under restriction and will be tested again in 60 days. If the second test is clear these cows can rejoin the herd. This process seriously disrupts farm business and can be very expensive. That is why it is important to try and prevent the disease from spreading. bTB can be spread from cattle to cattle, or from wildlife to cattle.<\/p>\n<p><strong><a id=\"pre-movement\"><\/a><\/p>\n<div class=\"description clearfix style-1\">As the disease is <span class=\"tooltips\"><a href=\"#\" rel=\"tooltip\" title=\"The ability of an infectious disease to pass from animals to humans or vice versa\"> zoonotic<\/a><\/span>, the use of raw milk on an affected farm is also restricted. The sale of raw milk and the production of any milk products from\u00a0unpasteurized\u00a0milk on the affected farm or using milk from the farm is prohibited until\u00a0the farm is officially cleared of infection. \u00a0In the U.S., laws regarding sales of raw milk vary by state.

However <a href=\"#ref\">Reilly and Courtenay<\/a> (2007) identify higher stocking densities as well as mixed enterprise as a protective risk factor. There is agreement that buying in cattle is a risk factor. The prevention of contact between cattle on neighboring farms is very important.

However, there is compelling evidence that the European Badger is the major wildlife reservoir and one of the main reasons for the TB breakdown in England and Wales. <em>M. bovis<\/em> is spread through saliva, sputum, urine, and feces of infected badgers. Direct observations and video surveillance has proven that badgers enter cattle sheds and feeds store where infected animals are able to shed <em>M. bovis<\/em> enhancing the likelihood of disease transfer (<a href=\"#ref\">Delahay et al., 2001<\/a>).<\/p>\n<p>In order to reduce TB, contact between badgers and your livestock needs to be minimized. In the case of badgers it is particularly useful to know where the setts are and which areas they utilize as latrines. Areas around badger sets should be fenced off to keep cattle out while allowing badgers free access. Badger latrines should also be fenced off for cattle (<a href=\"#ref\">Hutchings and Harris, 1999<\/a>). Active latrines are avoided by most cattle until the sward length in the rest of the field has reduced, after which there is an increasing likelihood that active badger latrines are grazed, especially by lower ranking cows (<a href=\"#ref\">Hutchings and Harris, 1997<\/a>). <a id=\"treatment\"><\/a>Overgrazing fields used by badgers should therefore be avoided. When cutting for hay or silage, grass from badger latrines and field margins should be also be avoided. Additionally badgers and other wildlife should be kept out of farm buildings, and doors should be secure and kept closed at night.
