Reduced fertility of sows causes economic loss to the piglet producers and also plays a major
role in sow mortality. Major aim of this study was to analyze the bacteriological aetiology of
endometritides and cystitides in sows.
39 sows from 7 farms in Lower Austria were sampled. Midstream urine was examined
macroscopically and physically-chemically. Another urine sample was taken under sterile
conditions directly out of the urinary bladder after slaughter. Furthermore a swab was taken
from the bladder and the uterus. A bacterial investigation of all four matrices was done by
LABOVET, GmbH laboratory for veterinary diagnostics and hygiene in Vienna. Statistical
analysis was done by means of Chi-square test with Yates` correction.
The most frequently detected bacteria of all analysed samples were Escherichia coli in
64.1 %, α-hemolytic streptococci in 34.6 % and Staphylococcus hyicus in 21.8 %. To lesser
extents, Enterococcus spp., Corynebacterium spp., β-hemolytic streptococci, Staphylococcus
spp., coagulase-negative staphylococci, Enterobacter agglomerans, Staphylococcus aureus
could be found.
To achieve most reliable bacteriological results, sterile urine as well as bladder swabs should
