Streptococcus equi subspecies zooepidemicus is a rare infection in humans associated with contact horses or consumption of unpasteurized milk products. On October 23, 2003, the National Public Health Institute was alerted that within one week three persons had been admitted to Tampere University Central Hospital (TaYS) because S. subsp. septicaemia. All consumed fresh goat cheese produced small-scale dairy located on farm. We conducted an investigation determine source and extent...
ABSTRACT In a longitudinal study in Finnish cattle finishing unit we investigated excretion and sources of Escherichia coli O157 bulls from postweaning until slaughter. Three groups 31 to 42 calves were sampled calf transporter before they entered the farm four seven times at approximately monthly intervals farm. All livestock negative for E. on arrival, whereas positive animals detected 1 day later. During fattening period infection rate varied between 0 38.5%. The also found be shedding...
In 1997 the first outbreak of Escherichia coli O157[ratio ]H7 infections involving 14 cases occurred in Finland. A case was defined as a resident Alavus with an episode diarrhoea between 5 and 17 July 1997, from whom E. isolated stool. The investigation included searching population-based control study. Five primary eight symptomatic secondary illness were detected. 10 days before outbreak, all patients (aged 3–8 years), but only 6 32 population controls same age range (Fisher's test, P...
Summary In May 2012, an outbreak of campylobacteriosis occurred in southern Sweden at a wedding reception affecting 44 persons. A total 17 cases were notified (13 culture positive for Campylobacter spp.). Epidemiological investigation suspected chicken liver pâté as the source infection. The had been deliberately undercooked, lightly fried to keep right texture and mixed with spices. isolates from six well three flocks previously raised by producer delivering subtyped using pulsed‐field gel...
The aim of this study was to evaluate antimicrobial resistance in canine staphylococci, Escherichia coli and enterococci, which were isolated from 22 dogs with pyoderma a history previous antibiotic treatment, compared bacterial isolates 56 non-treated control dogs. Two each species per dog investigated, if detected. Staphylococcal (35 isolates) more resistant sulphatrimethoprim than the controls (56 (57% vs. 25%, p < 0.004). Multiresistance staphylococci also common (29% 9%, = 0.02). A...
In 2016, an outbreak of Salmonella Typhimurium (STm) with multilocus variable-number tandem repeat analysis (MLVA) profiles historically associated passerine birds (2-[11-15]-[3-4]-NA-212) occurred among passerines, cats and humans in Sweden. Our retrospective observational study investigated the revisited historical data from 2009–16 to identify seasonality, phylogeography other characteristics this STm variant. Outbreak isolates were analysed by whole-genome single nucleotide polymorphism...
In April-May 2014, an outbreak of campylobacteriosis occurred after a preschool visit to dairy farm in the South Western part Sweden. During visit, meal, including unpasteurized milk, was served. A retrospective cohort study using web-based questionnaire performed among participants (n = 30) visit. total 24 30 (80%) members completed questionnaire. Eleven cases were identified, and Campylobacter jejuni isolated from eight them. Seven 2- 7-year-old children. We found highest attack rates...
Whole genome sequencing (WGS) is becoming a routine tool for infectious disease outbreak investigations. The Swedish situation provides an excellent opportunity to test the usefulness of WGS investigation outbreaks with Salmonella Dublin (S. Dublin) as epidemiological investigations are always performed when detected in livestock production, and index isolates from all herds stored therefore available analysis. This study was evaluate forward backward tracings infected S. Dublin.In this...
Pigs are the most important reservoir for human pathogenic Yersinia enterocolitica. We investigated herd prevalence of Y. enterocolitica in Swedish pig farms by analysing pen faecal samples using a cold enrichment 1 week and thereafter subsequent plating onto chromogenic selective media (CAY agar).Pathogenic was found 32 (30.5%) 105 sampled with finisher pigs. Bioserotype 4/O:3 identified at all but one farm, where 2/O:9 identified. Pen-prevalence within positive herds varied from 1/4 to 4/4...
Background Campylobacter jejuni is among the most frequent causes of bacterial gastroenteritis in Europe. Over 8,000 C. multilocus sequence typing types (STs) have been described; ST-21 and ST-45 identified as all human studies so far. In contrast to other STs, ST-22 has associated with Guillain–Barré syndrome ST-677 was recently linked severe systemic infections Finland. We investigated risk factors hospitalisation individuals acquired Sweden.MethodsA total 1,075 domestically infection...
Outdoor production of poultry is rapidly increasing, which could be associated with increased risks for exposure to different environmental sources Salmonella. We report a comparison on the occurrence Salmonella during 2007–2015 in broilers and laying hens outdoor indoor subjected same requirements prevention control as applied Sweden. Our results give no indication that, period studied, was higher than production. The annual incidence infected flocks remained at very low similar level For...
Several Proficiency Test (PT) or External Quality Assessment (EQA) schemes are currently available for assessing the ability of laboratories to detect and characterize enteropathogenic bacteria, but they usually targeting one sector, covering either public health, food safety animal health. In addition sector-specific PTs/EQAs detection, cross-sectoral panels would be useful assessment capacity foodborne pathogens in a One Health (OH) perspective further improving interpretation surveillance...
Background Livestock, domestic pets and wildlife can be intestinal carriers of thermotolerant Campylobacter species. These reservoirs in turn contaminate the environment food products, thus creating pathways to campylobacteriosis human beings. The purposes this study were investigate sampling strategies applied for surveillance on dairy cattle farms identify presence species different age groups. Methods Boot sock faecal samples collected from five herds three groups—cows, heifers calves...
Tick-borne encephalitis (TBE) is one of the most severe human tick-borne diseases in Europe. It caused by virus (TBEV), which transmitted to humans mainly via bites Ixodes ricinus or I. persulcatus ticks. The geographical distribution and abundance expanding Sweden as has number reported TBE cases. In addition tick bites, alimentary TBEV infection also been after consumption unpasteurized dairy products. So far, no Sweden, but knowledge about its prevalence Swedish ruminants scarce. present...
