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.

D009355	Neomycin	Aminoglycoside antibiotic complex produced by Streptomyces fradiae. It is composed of neomycins A, B, and C, and acts by inhibiting translation during protein synthesis.	Fradiomycin Sulfate,Neomycin Palmitate,Neomycin Sulfate
D002432	Cecum	The blind sac or outpouching area of the LARGE INTESTINE that is below the entrance of the SMALL INTESTINE. It has a worm-like extension, the vermiform APPENDIX.	Cecums
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
