listeriosis in scotland, 1988. 19892563856
an outbreak of an unusual strain of listeria monocytogenes infection in north-east scotland.listeria monocytogenes infection is an important cause of illness and hospitalization in vulnerable individuals. in the present study, we describe a community outbreak of listeria monocytogenes in the north-east region of scotland, which was epidemiologically, environmentally and microbiologically linked to a local meat product and ready-to-eat product manufacturer. infected individuals were interviewed, and an environmental investigation was conducted. clinical and environmental samples were te ...201526100074
the changing epidemiology of bacterial meningitis and invasive non-meningitic bacterial disease in scotland during the period 1983-99.we reviewed population-based laboratory reports of invasive meningococcal, pneumococcal, haemophilus influenzae, group b streptococcus (gbs) and listeria monocytogenes isolates in order to examine the changing epidemiology of meningitis and invasive non-meningitic disease (inmd) caused by these 5 pathogens in the 2 periods before (1983-91) and after (1992-99) routine use of h. influenzae type b conjugate vaccine (hib) in scotland. neissieria meningitidis was the most common cause of meningitis, ...200212064693
a survey of ethnic foods for microbial quality and aflatoxin content.a range of ethnic foods was examined for their microbiological content in relation to total viable counts (tvc) of aerobic bacteria, counts of presumptive coliforms, yeast and mould counts; presence of salmonella spp., listeria monocytogenes, escherichia coli o157:h7 and campylobacter spp.; total enumeration of clostridium perfringens, staphylococcus aureus and bacillus spp.; identification of moulds and the presence of total aflatoxins. samples, which included cereals, nuts, dried fruits, herbs ...200111288910
the incidence of listeria monocytogenes in farm bulk milks in ne scotland.raw milk samples (c. 20 ml) were taken from approximately 180 farm bulk tanks in the ne of scotland on 3 occasions over a period from august 1987 to february 1988 and tested for the presence of listeria monocytogenes. the maximum incidence of l. monocytogenes (3.8%) was found in the august sampling, with incidences of 1.02% and 2.7% in october and february. direct enrichment of 0.1 ml was negative and only 2 of the total of 14 positives were obtained by direct enrichment using 1.0 ml of milk, th ...19892517168
the incidence of listeria monocytogenes in raw milk from farm bulk tanks in north-east scotland.over 180 farm bulk milk tanks were tested for the presence of listeria monocytogenes on three separate occasions which included periods when cows were grazing and confined inside on a silage diet. the incidence of l. monocytogenes contamination was low, ranging from 3.8% in the summer samples to 1.0% in october. the level of contamination was estimated to be lower than one l. monocytogenes bacterium per ml in positive samples, as most required cold enrichment of 10-20 ml volumes before recovery. ...19892501262
ovine listerial encephalitis: analysis, hypothesis and synthesis.analysis of field data suggested that listerial encephalitis in sheep was most common in winter and early spring in the age groups of sheep which would be cutting, changing and possibly losing teeth. it was hypothesised that under these conditions ingested listeria monocytogenes could reach the fine dental terminals of the trigeminal nerve causing an ascending neuritis and encephalitis. experimental inoculation of organisms into the dental pulp demonstrated the feasibility of this route of infec ...19854002594
carriage of listeria monocytogenes and related species in pregnant and non-pregnant women in aberdeen, scotland.the faecal, cervico-vaginal and oropharyngeal carriage of listeria species in 54 healthy pregnant women and 60 healthy non-pregnant women was investigated. samples were cold-enriched at 4 degrees c and subcultured on selective media containing acriflavin, nalidixic acid and potassium thiocyanate. listeria monocytogenes was isolated from the faeces of one pregnant woman (2%) and two non-pregnant women (3.4%). listeria innocua was isolated from the faeces of one pregnant woman (2%) and one non-pre ...19863093591
outbreak of listeria meningoencephalitis in young lambs.an outbreak of listeriosis occurred in five-week-old lambs in a flock of 200 dorset ewes and 240 lambs in-wintered. nine lambs were lost within a period of 10 days. no cases of stillbirth or abortion or cerebral listeriosis occurred in the ewes. silage had been fed on this farm to both cattle and sheep for 10 years without any previous problems. a description of the outbreak and the findings are reported.19836415890
human listeriosis in scotland 1967-1988.in order to study the epidemiology of listeriosis from 1967-1988 in scotland, various sources of data were examined. these included reports by laboratories, reference laboratory records, hospital death and discharge records, death certificates and hospital laboratory records. cases were reported from 13 of scotland's 15 health boards. case ascertainment via laboratory reports to the communicable diseases (scotland) unit was validated in two health boards. a total of 198 cases was identified with ...19902111351
neonatal listeriosis in scotland.thirty-one cases of neonatal listeriosis occurred in scotland between 1 january 1987 and 31 august 1989. in each of these, listeria monocytogenes was cultured from blood, cerebrospinal fluid or both. no case of neonatal listeriosis occurred between 1 september 1989 and 31 july 1990, a statistically significant difference in incidence (p less than 0.001). a possible explanation may be that pregnant women adjusted their diet in accordance with the advice given by the chief medical officer in his l ...19911883183
the incidence and level of listeria monocytogenes contamination of food sources at primary production and initial processing.listeria monocytogenes was isolated in low numbers from a variety of environmental samples associated with the primary production of food, including vegetation, faeces and meat. the organism was rarely detected on growing grass and vegetables prior to processing. the excretion of l. monocytogenes by farm animals was linked to their diet, with animals fed entirely on hay or manufactured diets not excreting detectable levels of listeria (i.e. absence in 25 g). however, animals fed on silage, which ...19968972091
