摘要:
The present invention is directed to an isolated synthetic tripeptide of formula hd-phe-n-methyl-1-val-1-ala-ome (sequence id: 1), or a derivative thereof, and the corresponding lipotripeptides, which are: specific for mycobacterium avium subsp. paratuberculosis (map) of the s-type strain, as well as derivatives and conjugates thereof. The invention also relates to the use of these antigens in different methods and tests to detect map infection, especially by detecting humoral response and cell-mediated response of infected animals. The invention is also directed to a gene map signature and a characteristic signature obtained by mass spectrometry and nmr spectroscopy of the presence of map or map infection.a presente invenção é dirigida a um tripeptídeo sintético isolado de fórmula h-d-phe-n-metil-l-val-l-ala-ome (seq id no: 1), ou um derivado do mesmo, e aos lipotripeptídeos correspondentes, que são específico para mycobacterium avium subsp. paratuberculosis (map) da cepa tipo s, bem como derivados e conjugados dos mesmos. a invenção também se refere ao uso desses antígenos em diferentes métodos e testes para detectar a infecção por map, especialmente por meio da detecção da resposta humoral e resposta mediada por células de animais infectados. a invenção também é dirigida a uma assinatura gênica de map e uma assinatura característica obtida por espectrometria de massa e espectroscopia de rmn da presença de map ou infecção por map.
