Resumo
O objetivo do estudo foi avaliar o hemograma e o perfil bioquímico sérico, inclusive hemogasométrico, de bezerros infectados experimentalmente com Salmonella Dublin. Foram utilizados 12 bezerros sadios da raça Holandesa com 10 a 15 dias de idade, distribuídos aleatoriamente em dois grupos experimentais: grupo-controle (n= 6) e grupo infectado com 10(8)UFC de Salmonella Dublin (n=6). Os bezerros foram submetidos ao exame físico diário, e as amostras de sangue foram coletadas minutos antes da inoculação (0h) e 24, 48, 72, 96, 120, 144 e 168h após a inoculação. Além do hemograma e das análises hemogasométricas, foram mensuradas as atividades séricas das enzimas aspartato aminotransferase (AST), fosfatase alcalina (ALP), creatina cinase (CK), gamaglutamiltransferase (GGT) e lactato desidrogenase (LDH), e os teores de albumina, bilirrubinas, cálcio total, cálcio ionizado, sódio, potássio, cloretos, creatinina, ferro, fibrinogênio, fósforo, glicose, magnésio, proteína totais e ureia. As principais alterações foram: redução das concentrações de albumina, ferro, glicose, magnésio e proteína total, aumento do teor de fibrinogênio, leucocitose e acidose metabólica e hiponatremia.
The blood cell counts and biochemical profile, including blood gas levels, were evaluated, in Salmonella Dublin-infected calves. Twelve healthy 10 to 15-day old Holstein calves were randomly allotted into two groups: control (n=6) and group orally infected with 10(8) CFU Salmonella Dublin (n=6). The calves were submitted to physical examination and the blood samples were taken just before the inoculation (0h) and at 24, 48, 72, 96, 120, 144, and 168h later. Besides, blood cell counts, blood gas levels, and the serum concentrations of aspartate aminotransferase (AST), alkaline phosphatase (ALP), creatine kinase (CK), gammaglutamyltransferase (GGT), lactate desidrogenase (LDH), albumin, bilirubin, total calcium, ionic calcium, sodium, potassium, chlorides, creatinine, iron, fibrinogen, phosphorus, glucose, magnesium, total protein, and urea were measured. The main findings included decrease in albumin, iron, glucose, magnesium, and total protein concentrations, and increase in fibrinogen level, leukocytosis, metabolic acidosis, and hyponatremia.
