“…was quite high in this study (26.9%) and widely distributed (72.1% of operations), nearly all of the isolates (94.0%) were Salmonella enterica serotype IIIb 61:-:1,5,7, a serotype rarely associated with disease in people (Weiss et al, 1986). That the majority of isolates were S. enterica serotype IIIb 61:-:1,5,7 is consistent with previous findings in sheep in Canada, the United States, and Europe (Harp et al, 1981;Pritchard, 1990;Sandburg, 2002;Bonke et al, 2012). It is considered to be host adapted in sheep and rarely causes disease in otherwise healthy sheep (Greenfield, 1973).…”

“…A high rate of isolation of S. diarizonae from sheep tonsils at slaughter has been reported in Switzerland (Bonke et al, 2012). These observations indicate that sheep can carry this organism, but generally with no pathological consequences.…”

“…Segundo Bonke et al (2011), a infecção por Salmonella enterica subespécie diarizonae pode ser assintomática, pois 43% dos ovinos abatidos que continham o agente infeccioso em suas amígdalas não apresentavam qualquer sintoma.…”

“…A prevalência de Salmonella enterica subespécie diarizonae em amígdalas de ovinos coletadas em abatedouro foi de 43%, mostrando que há animais infectados que são assintomáticos e são fontes de infecção para outros animais (Bonke et al, 2011). Por outro lado, estudos realizados com camundongos infectados pela Salmonella enterica mostram que estes agentes possuem relativa resistência a antibióticos e migram para novos focos, podendo migrar de um foco inicial no intestino e colonizar novos órgãos, como fígado, testículo e epidídimo (Mastroeni et al, 2009).…”
