🦠 Serratia marcescens is a primary pathogen for swine semen that, according to the authors, is present in 10.3% of pig semen isolates (Althouse & Lu, 2005) or in 12.55% (Luis et al., 2013). It is also very important due to its multi-resistance. The main source of Serratias seems to be the boar although we have not been able to isolate it either in foreskin or in pure semen.

🐽 In addition, Serratia is an agent that easily contaminates the conduction systems and is resistant to the “usual” cleaning and disinfection steps performed routinely in the boar studs, thereby creating biofilms on wet surfaces that are difficult to access and can survive despite the cleaning measures that are set in the stud.

🖥️ A strict cleaning and disinfection monitoring, as well as an internal quality control capable of detecting slight changes in the behaviour of the produced doses, are decisive to be able to detect the problem before the seminal doses are used in the farm.
