RESUMO

Epizootiological, clinical, bacteriological and haematological studies were carried out to assess the effectiveness of the recently developed cephalosporin preparation Cefquinome in the treatment of the puerperal septicaemia and toxaemia syndrome. Cefquinome was administered at three different doses (1, 2 and 4 mg/kg BW) to 188 sows with feverish puerperal illness. Amoxicillin (7 mg/kg BW) was used as a control drug. In 41% of cases endometritis was a monoinfection whereas in 70% of mammary infections mixed infections were diagnosed. Results showed that for therapy of puerperal septicaemia and toxaemia Cefquinome at doses of 2 mg/kg BW and 4 mg/kg BW is clearly more effective than the control drug Amoxicillin and Cefquinome at its lowest dose of 1 mg/kg BW.

RESUMO

We examined the effect of infusion of lipopolysaccharide (LPS) on serum tumor necrosis factor alpha (TNF alpha) concentration and clinical attitude in 2- 3-day-old colostrum-fed (CF) and colostrum-deprived (CD) foals. Eleven CF and 8 CD neonatal foals were given a bolus i.v. infusion of Escherichia coli O55:B5 lipopolysaccharide (0.5 microgram/kg of body weight) in sterile saline (0.9% NaCl) solution. Four CF and 2 CD foals were given saline solution alone. Serum IgG concentration and serum anti-LPS IgG(T) antibody titer were determined for each foal prior to infusion. A depression index was used to score clinical abnormalities. Serum TNF alpha concentration was estimated by use of an in vitro cytotoxicity bioassay that used WEHI 164 clone 13 cells as targets. The cytotoxic serum factor was identified as TNF alpha by immunoprecipitation with caprine antisera raised against the 15 NH2-terminal amino acids of human TNF alpha. Tumor necrosis factor alpha was not detected in any preinfusion serum samples nor in any samples from foals given saline solution alone. Serum TNF alpha concentration increased in all LPS-infused foals and peaked between 60 and 90 minutes after infusion. Serum TNF alpha concentrations, expressed as mean percentage of peak serum TNF alpha concentration, persisted longer in CD foals given LPS than in CF foals given LPS. All LPS-infused foals displayed clinical signs of endotoxemia, but mean depression index scores of the CF and CD foals given LPS were not significantly different at any time. Serum TNF alpha concentrations were correlated with depression index scores in both LPS-infused groups.(ABSTRACT TRUNCATED AT 250 WORDS)
