Post Partum Bacteriology in Cows (Preliminary Date)
Abstract
The relationship of various clinical forms of uterine inflammation to bacterial contamination and the applicability of hydrogen peroxide for the intrauterine treatment of clinical endometritis was the subject of this trial. Uterine contamination was compared among groups of cows according to clinical findings on days 6 ± 3: MM, n = 7 (mild or severe puerperal metritis), SM, n = 7 (cows with severe puerperal metritis) and CM, n = 7 (cows without symptoms of puerperal metritis). After 21 ± 3 the seam cows (mild or severe clinical endometritis and controls without symptoms of the disease: MM, n = 7, SM, n = 7 and CM, n = 7). The applicability of 3% hydrogen peroxide was evaluated on cows after infusion 80 ml of the solution, clinical as well as a bacteriological examination of uteri in cows suffering from a postpartum pathology. A wider bacterial spectrum was found in the cows on day 6 ± 3 compared to day 21 ± 3. Arcanobacterium pyogenes and Bacillus spp were the main uterine contaminant in cows suffering from all clinical types of uterine inflammation while this bacterium was not shown to be present in any of the control cows. The results show an important role of A. pyogenes in the etiopathogenesis of all clinical forms of uterine inflammations in postpartum cows and support the use of 3% hydrogen peroxide for intrauterine treatment of clinical endometritis even though sufficient antibacterial effects of the treatment are still to be confirmed.
