Mastitis in Goats<\/h4>\n
Also known as Udder inflammation<\/strong><\/em><\/p>\n Mastitis is the term used to describe inflammation of the mammary glands, which may be caused by a number of different micro-organisms, mostly bacteria, but also viruses (e.g., lentivirus or caprine arthritis encephalitis<\/a>), fungi, and can also be caused by injury. Although of particular importance in dairy goats, mastitis can develop in any type and breed of doe regardless of its milk yield (Harwood, 2006<\/a>).<\/strong><\/p>\nEarly signs of mastitis include a drop in milk yield, modified milk texture, color, smell and\/or taste, lameness, and \/ or misshapen udders.<\/strong><\/p>\n<\/a>Small ruminant bacterial mastitis is often, but not only chronic and contagious, with infection spreading mainly during milking (Bergonier et al., 2003<\/a> ).<\/strong><\/div>\n\nWhich pathogens cause mastitis?<\/a>

Although sporadic, clinical mastitis caused by S. aureus<\/em> may result in gangrenous mastitis, characterized by necrotic<\/a><\/span> udder tissue which will eventually cause the udder to fall off, and the animal will die. The severity and painfulness of this disease makes S. aureus<\/em>-mastitis a threat to animal welfare.<\/p>\nS. aureus<\/em> has also been detected in many sub-clinical<\/a><\/span> cases, and it is not yet clear how these relate to clinical cases.<\/p>\nSub-clinical<\/a><\/span> Mastitis (SCM)<\/strong><\/h5>\nIn goats, coagulase-negative Staphylococci (CNS; which is made up of many different species of bacteria) are responsible for most cases of sub-clinical<\/a><\/span> mastitis. Sub-clinical<\/a><\/span> mastitis is characterized by reduced milk production, increased somatic cells<\/a> and bacterial presence in the milk, but it lacks the macroscopic<\/a><\/span> changes typical of the clinical stage.<\/p>\n<\/p>\n![\"Udder](\"https:\/\/www.farmhealthonline.com\/wp-content\/uploads\/2015\/01\/Udder-diagram-from-www.cell_.com-Trends-in-Biotechnology-300x189.jpg\")

<\/a>Mastitis occurs when bacteria invades the udder. Good milking hygiene, and good maintenance of the machinery are important in minimizing the amount of bacteria in the parlor and reduce the transmission of pathogens from infected to uninfected udders.<\/strong><\/p><\/div>\n<\/span>Teat damage<\/h3>\n
Mastitis develops when bacteria gain access to the udder, via the teat canal (see image above). The teat end can be damaged as a result of over milking, a poorly maintained milking machinery, rough removal of the clusters, getting teats caught on brambles or wire or as a result of teat biting. Teat-end damage allows bacteria to enter the teat canal, and can lead to mastitis.<\/p>\n
Viral mastitis<\/h3>\n
In goats there is a virus that particularly targets the udder, a lentivirus or caprine arthritis encephalitis virus, CAEV<\/a>. Clinical cases are known as \u2018hard udder\u2019. The acute form of this viral mastitis appears at parturition<\/a><\/span> as a very firm udder, but the <\/a>overlying skin is loose and free from swelling, and most importantly milk flow is almost absent (Koop et al., 2012<\/a>). Dairy goats that are seropositive<\/a><\/span> for CAEV, and have a negative bacterial culture can still have an increased Somatic Cell Count (See below<\/a>) (S\u00e1nchez et al., 2001<\/a>). Learn more about CEAV here<\/a> ).<\/p>\nSomatic Cell Count<\/h3>\n
Somatic cell counts (SCC) is a count of the number of body cells in a quantity of milk expressed as cells\/mL, and can be measured at either the gland level (the udder), individual animal level, or herd level (bulk milk SCC) (Koop et al., 2012<\/a>).<\/p>\nSCCs consist mainly of immune cells (leukocytes) that enter the milk compartment of the udder. There are always small quantities of immune cells in the milk, and their function is to protect the udder against infection by bacteria. Usually, the older the animal gets, the more somatic cells it tends to have in its milk. In dairy cows a relationship between SCC and mammary infections has long been demonstrated, and therefore, SCC are widely used to identify cows likely to have an intra-mammary infection. Most milk processing companies with use bulk milk somatic cell count (BMSCC) to estimate herd mastitis prevalence (Madouasse et al., 2010<\/a>). However this relationship is a lot more complex in goats.<\/p>\n
