Actinobaculum suis (Corynebacterium suis, Eubacterium suis, Actinomyces suis) was detected in the preputial diverticulum of 64,8% of 162 boars investigated in 8 districts of the region Omsk (Russian Federation) by indirect immunofluorescent technique. Until yet no informations were available about the prevalence of Actinobaculum (A.) suis in swine herds of the Russian Federation. The study shows that A. suis, as a main aetiological factor of cystitis and pyelonephritis in sows, is widely spread among the boars of the region Omsk. Prevalence of A. suis was not influenced by housing conditions, age or breed of investigated boars. Indirect immunofluorescent technique for detection of A. suis provides a good method for screening investigations with high numbers of samples.

Background: Actinobaculum suis is a bacterium known to cause infections of the urogenital tract of sows. Infection can occur through close contact to boars, who frequently carry the pathogen in their preputial diverticulum but do not become clinically diseased themselves. In the current case, Actinobaculum suis was isolated from pyogranuloma of inflamed epididymis in a boar with poor fertility.

Article Synopsis
- Urinary tract infections (UTIs) in sows are linked to serious reproductive issues, including decreased litter size and increased abortion rates.
- Actinobaculum suis is identified as a primary pathogen causing severe UTIs in pigs, with a study analyzing 23 strains from Brazil that utilized multiple genetic characterization methods.
- The strains showed sensitivity to certain antibiotics but exhibited 100% resistance to several others, while whole-genome sequencing provided new insights into the genetic differences among strains and represented the first genomic analysis of A. suis.

The remarkable host specificity of the species of the genus Actinobaculum led us to recharacterize these species by a polyphasic approach. A comparative chemotaxonomic study including analysis of whole-cell sugars, amino acid composition of the peptidoglycan, fatty acid methyl esters, respiratory quinones and polar lipids revealed significant differences that, in combination with molecular data, support a dissection of the genus Actinobaculum. The proposals of this study include the reclassification of Actinobaculum schaalii and Actinobaculum urinale as Actinotignum schaalii gen.

Actinobaculum suis is an important agent related to urinary infection in swine females. Due to its fastidious growth characteristics, the isolation of this anaerobic bacterium is difficult, thus impairing the estimation of its prevalence. The purpose of this study was to develop and test a polymerase chain reaction (PCR) for the detection and identification of A.
