Relative ability of orally administered Lactobacillus murinus to predominate and persist in the porcine gastrointestinal tract

Article Abstract:

The performance of orally administered Lactobacillus mutinus in the pigs of five cultures is studied for determining its ability to survive, predominate and persist in the porcine gastrointestinal tract. A strong basis for exploring the potential of porcine-derived isolates as probiotic feed additives for pigs is provided and further studies are necessary for characterizing their in vivo efficacy.

Insertional inactivation of determinants for Mg(super 2+) and Co(super 2+) transport as a tool for screening recombinant Lactococcus species clones

Article Abstract:

The potential of using the lactococcal Mg2+ and Co2+ transport orf18/corA provides as a tool for genetic manipulation of lactococci to eliminate background resistances when they are used in conjunction with another marker are investigated. It is observed that overexpression of orf18/corA resulted in cell growth inhibition on certain concentrations of CoCl2.

Variable bacteriocin production in the commercial starter Lactococcus lactis DPC4275 is linked to the formation of the cointegrate plasmid pMRC02

Article Abstract:

Research shows that the fluctuating levels of bacteriocin production by Lactobacillus lactis DPC4275 is linked to an 80-kilobase cointegrate plasmid formed by the incorporation of the lacticin 3147 genes into the bacterial plasmid. The pheotypic traits of this plasmid transconjugant are discussed.
