Gram-Negative Anaerobes in the Intestinal Flora of Pigs

Gramnegative anaerobe bakterier i svinets tarmflora

Abstract

A differential count of the gram-negative, anaerobic, non sporeforming bacteria in different segments of the pig intestinal tract was performed in 2 groups of pigs. Seventy-seven strains were identified, belonging to 6 groups: Sphaerophorus necrophorus, anhemolytic Sphaerophorus spp., Bacteroides (Eggerthella) spp., Fusobactenum spp., Veillonella/Acidaminococcus spp., and Peptostreptococcus elsdenii. The characters of these groups are described, and quantitative data on their occurrence in a group of normal porkers and a group of pigs with experimental swine dysentery are given.

Sammendrag

Der udførtes differentialtælling af gramnegative, anaerobe, non-sporogene bakterier i forskellige afsnit af tarmkanalen hos 2 grupper svin. Der identificeredes 77 stammer, som kunne henføres til 6 grupper: Sphaerophorus necrophorus, anhæmolytiske Sphaerophorus spp., Bacteroides (Eggerthella) spp., Fusobacterium spp., Veillonella/Acidaminococcus spp. og Peptostreptococcus elsdenii. Egenskaberne hos disse grupper beskrives og deres forekomst hos en gruppe slagterisvin og en gruppe svin med eksperimentel svinedysenteri angives.
