Relationship between isolation of L. monocytogenes from silage samples and their pH domestic species, the organisms are often found in the intestines of healthy cows as well as in the environment (1,7,8,16,17). This study also confirmed the presence of L. monocytogenes in areas where there had been no reports of listeriosis.…”

The prevalence of Listeria monocytogenes in the environment of dairy farms was surveyed from December 1993 to June 1994 in one city of Hokkaido. L. monocytogenes was isolated from 3 out of 5 farms investigated. Serovar 4b organism was isolated from the brain stem of a cow from one farmwhich was clinically diagnosed as having listeriosis. The same serovar of L. monocytogenes was also isolated from the rectal contents of a healthy cow, straw on the floor, straw in the barn, and silage scattered around the silo from the same farm. At another farm, with no reported cases of bovine listeriosis, serovar 1/2 organism was isolated from the same types of samples as the above mentioned farm except from straw on the floor. The difference in the isolation rates of the organism from straw on the floor between the two farms (22 % : 5/23 vs 0% : 0/24) is considered to be caused by the different feeding methods of silage between the two farms.

“…Do ponto de vista epidemiológico, com implicações ecológi-cas nas infecções por Listeria nos ruminantes, aponta-se a maior tendência de portadores entre os animais herbívoros, excretando pelas fezes a bactéria (Kampelmacher & van Noorle Jansen 1969, Skovgaard & Morgan 1988, Husu 1990, fato observado por Hofer (1974Hofer ( , 1983 em fezes de bovinos normais abatidos em matadouro. Aliado à presença de portadores de Listeria e a sua eliminação para o meio ambiente, salienta-se a capacidade de sobrevivência desta bactéria por períodos variá-veis em solos de diferentes qualificações (Lehnert 1960;Welshimer 1968, Hofer & Póvoa 1984, que favorecem a contaminação externa de vegetais (Weis 1975, Hofer 1975b) e alimentos ensilados (Gray & Killinger 1966, Skovgaard & Morgan 1988.…”

A análise fenotípica de 246 amostras do gênero Listeria isolados de animais portadores e doentes, provenientes de três regiões do país, colecionadas no período de 1971 a 2000, permitiu caracterizar as espécies e sorovares prevalentes. Dentre os animais predominaram os espécimes fecais de bovinos normais (217 amostras, 88,2%), em contraposição aos 29 isolados (11,7%) de Listeria de animais doentes, apresentando comprometimento do sistema nervoso central (15 amostras, 6,0%) e outras localizações sistêmicas (14 amostras, 5,6%). Quanto às espécies e sorovares, predominaram L. innocua 6a e não tipável (140 amsotras, 56,9%) e L.monocytogenes 4a (37 amostras, 15,0) e 4b (22 amostras, 8,9%) principalmente nas fezes de bovinos hígidos e nos animais doentes, L. monocytogenes sorovares 4b (14 amostras, 5,6%) com destaque nos ruminantes e 1a (8 amostras, 3,2%) incidindo nas outras espécies animais (roedores e canídeos) e tendo localizações prevalentes em áreas distintas ao sistema nervoso central.

“…Shedding of the pathogen by a variety of domestic animals like sheep and cattle has been reported [16][17][18][19][20]. A possible route of infection into the human food chain, for instance, is through the ingestion of uncooked food plants grown on soils irrigated with contaminated water or via the consumption of vegetables cultivated on manure treated fields [21][22][23][24]. Also, ready-to-eat food or dairy products that have not been pasteurized, such as raw milk cheese or smoked salmon pose significant risks to consumers.…”

During a 1-year longitudinal study, water, sediment and water plants from two creeks and one pond were sampled monthly and analyzed for the presence of Listeria species. A total of 90 % of 30 sediment samples, 84 % of 31 water plant samples and 67 % of 36 water samples were tested positive. Generally, most probable number counts ranged between 1 and 40 g were detected. Species differentiation based on FT-IR spectroscopy and multiplex PCR of a total of 1220 isolates revealed L. innocua (46 %), L. seeligeri (27 %), L. monocytogenes (25 %) and L. ivanovii (2 %). Titers and species compositions were similar during all seasons. While the species distributions in sediments and associated Ranunculus fluitans plants appeared to be similar in both creeks, RAPD typing did not provide conclusive evidence that the populations of these environments were connected. It is concluded that (i) the fresh-water sediments and water plants are year-round populated by Listeria, (ii) no clear preference for growth in habitats as different as sediments and water plants was found and (iii) the RAPD-based intraspecific biodiversity is high compared to the low population density.Keywords: biodiversity; fresh water; Listeria monocytogenes; Listeria spp.; sediment; water plants.Dedication: This work is dedicated to the memory of Professor Peter Böger. His continuous support and thoughtful guidance over many years encouraged the senior author to aim at an academic career in microbial ecology and evolutionary biology.
