The bacterium Lawsonia intracellularis causes the disease proliferative enteropathy. The bacterium is present in >40% of the Swedish piglet-producing herds and production losses are estimated to 2 900 SEK per sow and year. The disease is spread by faeces and the pigs are usually affected after weaning. Sick pigs may be diagnosed by e.g. PCR. To identify infected herds, antibodies can be demonstrated in blood samples, but there are indiciations that the only, commercially available method lack specificity. Since these serological analyses are cost effective and may be applied to a large number of samples, this is very unfortunate. The aim of this study is to identify a L. intracellularis-specific protein to develop a reliable diagnostic method, ELISA, for the demonstration of Lawsonia-specific antibodies in blood samples. Such a method can be very useful in surveillance of L. intracellularis at the herd level, to demonstrate the presence of or to verify freedom from the infection.
Bakterien Lawsonia intracellularis orsakar sjukdomen proliferativ enteropati som förekommer i minst 40 % av de svenska smågrisbesättningarna. Sjukdomen beräknas kosta 2 900:- per sugga och år. Bakterien sprids med avföring och smågrisarna insjuknar vanligen efter avvänjning. Hos enstaka sjuka djur kan bakterien påvisas med t.ex. PCR. För övervakning på besättningsnivå krävs metoder för att påvisa antikroppar i blod men det finns indikationer på att den enda, kommersiellt tillgängliga metoden inte är specifik. Eftersom sådana så kallat serologiska metoder är kostnadseffektiva och kan göras på ett stort antal prov, är detta mycket olyckligt. Studien syftar till att ta fram ett protein som är specifikt för L. intracellularis och utveckla en tillförlitlig diagnostik (ELISA) för att påvisa antikroppar i blodprov. En sådan metod kan få stor användning i övervakningen av L. intracellularis på besättningsnivå, för att påvisa förekomst eller kontrollera frihet från infektionen.

Every year, about 500,000 claw trimmings are recorded in Swedish dairy cattle. The aim of claw trimming is to detect, treat and prevent painful claw lesions. However, the claw trimming in itself can be harmful and cause claw lesions if it is not done correctly. The aim of the project is to develop …
