Ability of intestinal Escherichia coli to survive within mesenteric lymph nodes

Identification of mesenteric lymph node (MLN) bacteria showed that indigenous streptomycin-sensitive Escherichia coli could be recovered from MLN at least 48 h after this organism had been essentially eliminated from the cecal flora by antibiotics and replaced with exogenous streptomycin-sensitive E. coli JK. Additional experiments with antibiotic-treated rats also showed that indigenous streptomycin-sensitive E. coli could be recovered from the MLN 4 days after elimination of this organism from the cecal flora. These findings suggest that the time of bacterial translocation to MLN may be kinetically different from the time of recovery of bacteria from MLN and that the MLN may be a focus of infection with intestinal bacteria.</jats:p

Nutzung von Prozessen der Biosorption und Akkumulation zur Metallabtrennung und Rueckgewinnung aus belasteten Abwaessern mit dem Ziel der Umweltsanierung Abschlussbericht

Es wurden Grundlagenuntersuchungen zur Biosorption von umweltrelevanten Schwermetallen mit verschiedenen mikrobiellen Adsorbentien durchgefuehrt und an technischen Abwaessern Technologievorschlaege erarbeitet. Zur Verbesserung der Technologie von Biosorptionsprozessen wurden Moeglichkeiten der Steigerung der Sorptionsleistung von Biosorbentien erarbeitet und Untersuchungen zur Immobilisierung der biologischen Adsorbentien durchgefuehrt. (orig.)Fundamental investigations into the biosorption of environmentally relevant heavy metals were carried out with different microbial adsorbents, and processes were proposed for industrial effluents. In order to improve the technology of biosorption processes, attempts were made to improve the sorption efficiency of biological sorbents, and investigations were carried out on the immobilisation of biological adsorbents.
