[Coagulase-negative Staphylococcus species in mixed fodder and on grain]

For valuation of microbially-altered combined fodder from the veterinary point of view beside the total number of germs also the diagnosis of the species of veterinary relevant indicator germs is of importance. Coagulase-negative staphylococci are the main and indicator flora in spoiling of combined fodder. According to the biochemical and physiological characterization the majority of the coagulase-negative staphylococci occurring in connection with spoiling of combined fodder belongs to the species S. xylosus. Beside the species also other coagulase-negative species as S. sciuri, S. cohnii, S, warneri and S. saprophyticus have been demonstrated. These bacterial species were also found in the single components of combined fodder as ripe grain, green unripe cereal plants, in soil samples and in the dust inside the mills for combined fodder production.
