An outbreak is usually confined to one lambing season (<a href=\"#ref\">The Henston Vade Mecum, 1998<\/a>), but may recur after a 5-7 year gap. Seasonality in <em>Campylobacter<\/em> spp. recovery from cattle and sheep in Great Britain has been reported.<\/p>\n<p><em>Campylobacter<\/em> spp. can be carried in the intestines and gall bladder of healthy sheep without causing clinical diseases (<a href=\"#ref\">Mannering <em>et al<\/em>., 2006<\/a>), in fact intestinal infection is probably close to 100%, however it is the shedding of <em>Campylobacter<\/em> spp. that varies with season and diet.<\/p>\n<p><a id=\"control_prevention\"><\/a>A study of <em>Campylobacter<\/em> spp. shedding by grazing sheep on lowland farm land, saltmarsh and upland fells in North Lancashire, UK, revealed that the organism was intermittently shed depending on season. <em>Campylobacter<\/em> spp. shedding was lowest (0%) in November and December when sheep were fed on hay and silage compared with when they were grazing pasture (<a href=\"#ref\">Jones <em>et al<\/em>., 1999<\/a>). The highest rates of shedding (100%) coincided with increased stress as a result of lambing, weaning and movement onto new pasture.<\/p>\n<h3>Effects of Lambing on Colonisation of <em>Campylobacter<\/em> in Ewes<\/h3>\n<p>The same study in North Lancashire, UK found that ewes that were not shedding <em>Campylobacter<\/em> spp. before lambing began shedding 3\u00a0days after lambing while ewes that shed low numbers before lambing subsequently shed huge amounts of <em>Campylobacter<\/em> spp. after lambing, and within 5\u00a0days of being born, 100% of lambs born to either set of ewes were colonized (<a href=\"#ref\">Jones <em>et al<\/em>., 1999<\/a>).<\/p>\n<div class=\"hr hr3\" style='margin:20px 0 20px 0 !important;'><\/div>\n<h4><a id=\"control_prevention\"><\/a>Control and Prevention of Campylobacteriosis<\/h4>\n<p><span class=\"responsive\"><\/p>\n<div id=\"attachment_6574\" style=\"width: 310px\" class=\"wp-caption alignright\"><a href=\"https:\/\/www.farmhealthonline.com\/wp-content\/uploads\/2015\/09\/Outdoor-lambing.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-6574\" class=\"size-medium wp-image-6574\" src=\"https:\/\/www.farmhealthonline.com\/wp-content\/uploads\/2015\/09\/Outdoor-lambing-300x200.jpg\" alt=\"Outdoor lambing\" width=\"300\" height=\"200\" srcset=\"https:\/\/www.farmhealthonline.com\/wp-content\/uploads\/2015\/09\/Outdoor-lambing-300x200.jpg 300w, https:\/\/www.farmhealthonline.com\/wp-content\/uploads\/2015\/09\/Outdoor-lambing.jpg 640w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-6574\" class=\"wp-caption-text\"><strong>Care should be taken on farms which practice outdoor lambing, as <em>Campylobacter<\/em> spp can remain viable in uterine discharge and fetal membranes for several days.<\/strong><\/p><\/div>\n<p><\/span>Abortion occurs 7-25 days after infection and spreads rapidly due to the large numbers of organisms in aborted material.
