“…cheeses were ripened for 11 days at 12-13°c and 95% relative humidity of the air, and then stored for another 11 days at 6°c (closed circles, control; closed triangles, with phage a511; open diamonds and dotted line, surface ph). 25 For phage indicator strain L. ivanovii WSLC 3009 cm r , chloramphenicol (7.5 μg/ml) (Sigma) was added to the media. Phage A511 lysates were prepared and purified as previously described in reference 31.…”

“…The latter had been isolated in 2005 from a listeriosis outbreak in Switzerland, involving white mold soft cheese. 25 Thus, it appears to be better adapted to this specific environment than strain Scott A, which is a clinical isolate, 26 and had been held under laboratory conditions for many years. Similar observations regarding L. monocytogenes strain-specific growth differences have been reported for other cheese models and related studies.…”

“…This underlines the public health and economic impact that an outbreak associated with this food type might have. In the past decades, Switzerland was hit by such outbreaks twice: from 1983 to 1987 in connection with "Vacherin Mont d'Or" soft cheese, which led to a high mortality and a high number of encephalitis cases, as well as in 2005 related to "Tomme" soft cheese (Büla et al, 1995;Bille et al, 2006). As a consequence to the 1983 to 1987 outbreak the Swiss government decreed the creation of the Listeria Monitoring Program (LMP), which is still in effect today.…”

“…Although an association between listeriosis in animals and the ingestion of contaminated feed had already been suggested in the 1960s, it was not until the 1980s that L. monocytogenes was recognized as a causative agent of food-borne outbreaks in humans (Schlech et al, 1983). Since then, it has been associated with a wide range of different foodstuffs, including two types of Swiss soft cheese (Büla et al, 1995;McLauchlin, 1996;Bille et al, 2006). Compared to other food-and feed-borne infections, listeriosis is a relatively rare disease.…”

Listeria (L.) monocytogenes is widely distributed in the environment, but also has the ability to cause serious invasive disease in ruminants and humans. This review provides an overview of listeriosis in ruminants and discusses our insufficient understanding of reservoirs and possible cycling ofL. monocytogenes between animal and human hosts, food and the environment. It indicates gaps in our knowledge of the role of genetic subtypes in L. monocytogenes ecology and virulence as well as risk factors, in vivo diagnostics and pathogenesis of listeriosis in ruminants. Filling these gaps will contribute to improving the control of L. monocytogenes and enhancing disease prevention. As the prevalence of listeriosis in ruminants in Switzerland is likely to be underestimated, propositions concerning improvement options for surveillance of listeriosis in ruminants are provided.

“…Two large outbreaks in human population were reported from California, (Linnan et al, 1988), and Switzerland, (Bille, 1990). Another listeriosis outbreak occurred in Switzerland during 2005 (Bille et al, 2006). Two outbreaks of listeriosis were reported in Finland, in 1998and 1999(Lyytiksinen et al, 2000Maijala et al, 2001).…”

Listeria monocytogenes is the causative organism of listeriosis, which primarily affects immunecompromised individuals, including pregnant women. Contamination of milk and milk products with L. monocytogenes is a serious problem to the world and to the developing countries like Sri Lanka. Even the presence of low numbers of L. monocytogenes is a potential risk since this organism is capable of multiplying at ambient and under refrigerated conditions. The main aim of the study is to detect the circulating serotypes in dairy industries using molecular methods and primarily to trace the lineage of these serotypes with a focus on food safety and disease prevention. Altogether total of 266 samples from raw milk, pasteurized milk, ice cream, curd, yogurt and cheese were collected from many parts of the country, tested for the presence of L. monocytogenes and studied the serotype. L. monocytogenes was detected in all types of the above-mentioned milk and milk products. Out of total L. monocytogenes strains detected by PCR, 61.51%, 11.53% and 4% belong to serotypes 1/2a (or 3a) [lineage II], 1/2b (or 3b) [lineage I] and, 1/2c (or 3c) [lineage II] respectively. It has been observed previously that serotypes (1/2a), 1/2b) isolated from raw milk samples been linked to multiple human listeriosis outbreaks. This study revealed the serotypes of L. monocytogenes circulating in Sri Lanka, thus makes an alarm to the health authorities to be more vigilant about the probable outbreaks of listeriosis in Sri Lanka. This is the first report on circulating L. monocytogenes serotypes in Sri Lanka.All copyrights reserved to Nexus® academic publishers
