New perspectives on the gastrointestinal mode of transmission in invasive Listeria monocytogenes infection.

摘要: The route or mechanism of transmission Listeria monocytogenes from its rural veterinary reservoir to newborn and older human populations has been obscure. Anecdotal reports milk-borne infection cows with mastitis have published, but intensive investigations small outbreaks L. infections in humans not supported a gastrointestinal mode infection. Several recent studies, however, strongly suggest this possibility, case-control studies epidemic listeriosis the Canadian Maritime provinces 1981 documented an association between ingestion uncooked vegetables development illness (p = 0.02). In that study, coleslaw regional producer which was distributed throughout Maritimes considered be vehicle transmission. Cabbage, raw product production coleslaw, contaminated at farm prior arrival plant. Contamination occurred through fertilization manure flock sheep known harbour monocytogenes. Therefore, indirect link established on cabbage subsequent invasive humans. This study supports findings other epidemiologic is consistent results into natural laboratory-acquired animals.
