A total of 120 (80 males and 39 females) newborn Holstein-Frisian calves suffering from acute diarrhoea were studied clinically and biochemically, including the following parameters: pH, pCO2, act. HCO3, BE, RBC, PCV, HV, glucose lactate, urea, creatinine, total bilirubin, total protein, AST, Na, K and Cl. The results were interpreted according to their healthy condition, their age as well as their sex. The study had revealed an extreme metabolic acidosis, haemoconcentration, hypoglycaemia and hypofunction in the kidney and liver. Furthermore, the calves with diarrhoea had showed hyponatraemia, hypochloraemia, and hyperkalaemia. Important correlations between clinical and some blood parameters were found. Metabolic acidosis was more severe in male calves than females. These pathophysiological changes should be put in consideration during the therapy of newborn calves suffering from diarrhoea.  相似文献

Analysis of caprine IgG1 and IgG2 subclass responses to Chlamydia psittaci infection and vaccination     

N Schmeer  H Krauss  J Apel  M Adami  H P Müller  W Schneider  J A Perez-Martinez  H Rieser 《Veterinary microbiology》1987,14(2):125-135

Enzyme-linked immunosorbent assays (ELISAs) specific for caprine IgG(H+L), IgG1 and IgG2 were developed and evaluated for serodiagnosis of Chlamydia psittaci infections in a Tunisian goat flock with currently occurring chlamydial abortions and a clinically inapparent goat flock of an animal research facility. Additionally, ELISAs were applied to record the IgG1 and IgG2 dynamics of four goats vaccinated with inactivated Chlamydia psittaci and Coxiella burnetii. For screening purposes, the IgG(H+L) ELISA proved to be superior to the complement fixation test because it detected a larger number of chlamydial abortions and was easier to perform and to interpret. Analysis of Chlamydia psittaci-specific IgG1 and IgG2 responses to naturally occurring infections by ELISA revealed high IgG1 levels associated with IgG2 in goats with current abortions, whereas clinically inapparent, but seropositive goats were characterized by significantly lower IgG1 levels only (P less than 0.001). Similarly, the four vaccinated goats responded initially with Chlamydia psittaci-specific IgG1, whereas second and third vaccinations induced (as in goats with chlamydial abortions) predominantly IgG1, but also IgG2. The results indicated that clinically inapparent chlamydial infection may be distinguished from overt disease by analysing specific IgG1 and IgG2 responses. Applying Coxiella burnetii- specific ELISAs on field samples, IgG1 alone could be detected in eight, IgG2 alone in one and IgG1 combined with IgG2 in nine goats. The coxiella-specific antibody response of the four vaccinated goats was--in contrast to the chlamydia-specific response--characterized by IgG2 dominance.  相似文献

Pharmacokinetics and bioavailability of spiramycin in pigs.     

H M Sutter  J Engeli  P Müller  B Schneider  J L Riond  M Warner 《The Veterinary record》1992,130(23):510-513

The pharmacokinetics of spiramycin in pigs were investigated after intravenous and oral administration. The potential therapeutically effective blood level was established after a single administration and examined in a subsidiary five day study. The rapid intravenous injection of 25 mg spiramycin/kg bodyweight produced marked salivation in all the test animals. The elimination half-life (2.3 +/- 1.2 hours) was relatively short, in accordance with the total body clearance rate (27.3 +/- 10.1 ml/minute/kg). The high volume of distribution (5.2 +/- 2.2 litres/kg) was due to the accumulation of the drug in the body tissues. The maximum plasma concentration (4.1 +/- 1.7 micrograms/ml) after oral administration of 85 to 100 mg spiramycin/kg bodyweight was reached after 3.7 +/- 0.8 hours and the half-life of the elimination phase was 6.0 +/- 2.4 hours. The oral bioavailability was 45.4 +/- 23.4 per cent. Ad libitum feeding of a diet containing 2550 mg spiramycin/kg produced a steady state concentration of 0.96 +/- 0.27 micrograms/ml. This plasma concentration would provide a potentially therapeutically effective blood concentration against Mycoplasma species, Streptococcus species and Staphylococcus species.  相似文献
