Title: Evaluation of pyelonephritis in culled indoor and outdoor high parity sows. Author: Almanjd P, Bilkei G. Journal: Dtsch Tierarztl Wochenschr; 2008 Jan; 115(1):34-7. PubMed ID: 18265757. Abstract: UNLABELLED: The present trial was conducted in Hungary in neighboring large indoor and outdoor pig production units, belonging to the same breeding company. Rejected kidneys from 201 (out of 241; 83.4%) outdoor, and 191 (out of 512, 37.3%) indoor high parity sows, with previous history of recidiving postparturient fever and excessive postparturient vulvovaginal discharge were gross pathologically bacteriologically, and histologically evaluated. All rejected kidneys revealed chronic pyelonephritis. In outdoor sows Escherichia (E.) coli and Actinobaculum (A.) suis were cultured from all kidneys. Besides E. coli and A. suis, Clostridium spp., Arcanobacterium pyogenes, gram-positive streptococci (enterococci, Streptococcus faecalis), staphylococci (Staphylococcus (S.) albus, S. epidermis, S. aureus), Erysipelothrix rhusiopathiae, and Klebsiella spp. were concurrently found in 131 (64.7%) kidneys; Pseudomonas aeruginosa, Citrobacter, Pasteurella multocida, Proteus spp. were concurrently found beside E. coli and A. suis in 71 (35.3%) kidneys. In indoor sows E. coli and A. suis were cultured from all kidneys as well. Pseudomonas aeruginosa, Citrobacter, Pasteurella multocida, Proteus spp. were found beside E. coli and A. suis in 21 (11%) kidneys. However only 6 sows (3.1%) revealed the concurrent presence of Clostridium spp., Arcanobacterium pyogenes, gram-positive streptococci (enterococci, Streptococcus faecalis), staphylococci (S. albus, S. epidermis, S. aureus), Erysipelothrix rhusiopathiae, and Klebsiella spp. IMPLICATIONS: in Eastern European climate, more high parity outdoor sows with recidiving postparturient fever and vulvovaginal discharge have pyelonephritis and higher diversity of pathogenic bacteria in the renal pelvis compared with indoor sows.[Abstract] [Full Text] [Related] [New Search]
