Provedor de dados: Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Autores: Jatobá,A.; Moraes,A.V.; Steckert,L.D.; Jesus,G.F.A.
ABSTRACT This study aimed to isolate native lactic acid bacteria of yellow tail lambari (Astyanax bimaculatus) and evaluate their effect on host microbiota and gut morphology, as well as survival after experimental challenge. The isolated bacterial strains were evaluated for their inhibition against pathogenic bacterial strains in vitro, and the strain with highest inhibitory ability was molecularly identified as Lactobacillus spp. For in vivo testing, eighty fish were distributed in ten tanks equipped with a recirculation system. The experimental units were divided into two treatments: fish fed with Lactobacillus spp. supplement and fish fed an unsupplemented diet (control). After 30 days, guts from three fish from each experimental unit were pooled for...

Bovine response to lipoarabinomannan vaccination and challenge with Mycobacterium paratuberculosis
Provedor de dados: Brazilian Journal of Microbiology
Autores: Jolly,Ana; Morsella,Claudia; Bass,Laura; Fiorentino,María Andrea; Paolicchi,Fernando Alberto; Mundo,Silvia Leonor.
This study aimed to evaluate the immune response in bovines following immunization with a mycobaterial Lipoarabinomannan extract (LAMe) and the effect of Map challenge. LAMe vaccine induced specific antibody levels that diminished after the challenge and affected Map excretion at least for 100 days thereafter.
