Caseous Lymphadenitis in Goats<\/h4>\n
Also known as <\/strong><\/em>Corynebacterium pseudotuberculosis<\/strong>, CLA, CL, Lumpy neck, Lymphadenitis and Visceral Lymphadenitis<\/strong><\/em><\/p>\n<\/p>\nCaseous Lymphadenitis (CL) is a highly contagious disease of goats and sheep caused by a bacterium called Corynebacterium pseudotuberculosis<\/em> (C. pseudotuberculosis<\/em>).\u00a0 This potentially zoonotic<\/a><\/span> pathogen <\/a><\/span> occurs worldwide and has also been reported in horses, cattle, llamas, alpacas and buffalo (Fontaine and Baird, 2008<\/a>). \u00a0It causes a chronic<\/a><\/span> disease that can be difficult to control once it has established on the farm. CL infections are often wrongly perceived to be relatively harmless but actually causes serious disease in goats (and sheep). On farms where it is endemic<\/a><\/span> \u00a0it has substantial \u00a0economic consequences through the loss of fertility, gradual emaciation and condemnation or down grading of carcasses at the abattoir (Al-Gaabary et al., 2009<\/a>; Connor et al., 2000<\/a>).<\/strong><\/p>\n<\/div>\n\nTransmission of\u00a0CL<\/a>

\nGood Practice<\/a> <\/div>\n<\/div>\n<\/div>\n<\/a>Caseous lymphadenitis infections occur in two forms, external<\/a> and internal<\/a> (often referred to as visceral).<\/p>\nExternal caseous lymphadenitis<\/h3>\n
CL infections usually result in external pus-filled abscesses ranging in size from millimetres to centimetres, \u00a0in the lymph nodes<\/a><\/span> in the head and neck, but the lymph nodes<\/a><\/span> and subcutaneous<\/a><\/span> tissue of the limbs and torso can also be affected (Nagel-Alne et al., 2015<\/a>).<\/p>\n<\/a>Wool or hair over the abscess is often lost, then it ruptures releasing huge numbers of bacteria (about 1-5 million per gram) onto the skin and hair\/fleece resulting in the subsequent contamination of the immediate environment. (Fontaine and Baird, 2008<\/a>).<\/p>\nInternal caseous lymphadenitis<\/h3>\n
CL can also cause internal (often called visceral) abscesses. They\u00a0form in the internal lymph nodes<\/a><\/span> and the lungs, although other tissues can be affected, including the liver, kidneys or mammary glands, and less frequently the heart, brain, spinal cord, testes, uterus and joints (Valli and Parry, 1993<\/a>). If an abscess in the <\/a>mammary gland bursts, the pus can potentially infect the milk (Harwood, 2006<\/a>). If the herd is completely na\u00efve to infection, the visceral form can be common and mortality can be high. However in previously exposed herds visceral abscesses are rare.<\/p>\nClinical signs which accompany visceral CL infection include progressive weight loss, respiratory disorders and a swollen gut (Oreiby, 2015<\/a>).<\/p>\nTransmission of caseous lymphadenitis<\/h3>\n
Until the external abscess bursts, goats are not too infections, however the main mode of transmission of C. pseudotuberculosis<\/em> is by\u00a0direct contact animal-to-animal from bacteria excreted from ruptured abscesses.. Caseous lymphadenitis can also be spread indirectly from pen fixtures and feed troughs. It is <\/a>thought that bacteria invade through minor wounds and abrasions and travel via the lymphatic system to the nearest internal lymph node<\/a><\/span> which then becomes infected.<\/p>\nBased on current knowledge. CL causes mastitis only if the abscesses are present in the mammary glad.<\/p>\n

<\/a>Shearing equipment used on animals farmed for their fleece such as the Angora goats in the image, may serve to transfer Caseous lymphadenitis between herds.<\/strong><\/p><\/div>\n<\/span><\/p>\n
<\/a>Caseous lymphadenitis and shearing<\/strong><\/h5>\nThere is evidence a major risk factor for spreading CL is shearing (Binns et al., 2002<\/a>; Serikawa et al., 1993<\/a>).\u00a0C. pseudotuberculosis<\/em> can be transmitted on shearing equipment, clothing and mobile handling equipment. Wounds that arise are likely sources of\u00a0entry for C. pseudotuberculosis.\u00a0<\/em>\u00a0The use of shearing contractors (as opposed to doing it yourself)\u00a0has been identified as a an additional risk factor in the spread of CL in the sheep sector\u00a0 (Binns et al., 2002<\/a>).<\/p>\nThis will be the same in the goat sector so farms who commercially rear goats for fibre should take extra precautions to ensure that shearing hygiene is paramount. Additionally, there is research to suggest that spraying iodine tincture on shearing wounds is effective in protecting stock from CL infection (Serikawa et al., 1994<\/a>).\n<\/div>\nControl and Prevention of Caseous Lymphadenitis in Goats<\/h4>\n

<\/a>Before purchasing stock, check them for\u00a0swollen glands as this is a key sign for caseous lymphadenitis. However, goats which appear healthy may also be harbouring disease so quarantine is still very important.<\/strong><\/p><\/div>\n<\/span>The best means of prevention is keeping the infection off the farm. A closed herd is the safest and easiest way to keep the disease off the farm as any purchased goat is a potential risk. If you have to buy replacements avoid buying goats with swollen glands. Seemingly healthy goats may still be incubating the disease so a robust quarantine procedure is also important. It is recommended that new stock is kept away from the main herd for at least 2 months and observed and handled regularly to look for signs of swollen glands (Harwood, 2006<\/a>).<\/p>\n
