ABSTRACT

Serum protein concentrations, including acute phase proteins (APPs), of goats and ewes with naturally acquired Sthaphylococcus aureus mastitis were determined by means of SDS-PAGE electrophoresis to evaluate the relevance of these APPs as biomarkers of the disease in these species. Fifteen healthy goats and 5 goats with naturally acquired staphylococci mastitis, as well as fifteen healthy ewes and 5 ewes with staphylococci mastitis were submitted to daily blood sampling during 7 days. In goats, an increase of 570%, 125%, 621%, and 279% in serum concentrations of ceruloplasmin, fibrinogen, haptoglobin and α1-acid glycoprotein, respectively, was observed. In sheep the increase in serum concentrations of ceruloplasmin, fibrinogen, haptoglobin and α1-acid glycoprotein was of 337%, 90%, 461%, and 225%, respectively. Our results indicate that these APPs have considerable potencial as early and sensible biomarkers of mastitis caused by S. aureus in goats and sheep.(AU)


O proteinograma, incluindo proteínas de fase aguda (PFAs), de cabras e ovelhas com mastite de origem natural causada por Staphylococcus aureus, foi determinado por meio de eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE) a fim de avaliar a importância destas PFAs como biomarcadores da enfermidade nestas espécies. Amostras de sangue foram colhidas diariamente de cinco cabras e cinco ovelhas com mastite estafilocócica naturalmente adquirida, bem como de quinze cabras e quinzes ovelhas saudáveis durante 6 dias consecutivos. Nas fêmeas caprinas, foi verificado aumento dos teores séricos de ceruloplasmina (570%), fibrinogênio (125%), haptoglobina (621%), e α1-glicoproteína ácida (279%). Nas fêmeas ovinas as concentrações de ceruloplasmina, fibrinogênio, haptoglobina e α1-glicoproteína ácida elevaram-se em 337%, 90,9%, 461% e 225%, respectivamente. Os resultados permitem inferir que estas PFAs são marcadores sensíveis e precoces de mastite causada por S. aureus em cabras e ovelhas.(AU)
