RESUMEN
BackgroundBloodstream infections (BSI) cause substantial morbidity and mortality.AimWe explored the role of causative pathogens and patient characteristics on the outcome of community-acquired (CA) and healthcare-associated (HA) BSI, with particular interest in early death.MethodsWe used national register data to identify all BSI in Finland during 2004-18. We determined the origin of BSI, patients´ underlying comorbidities and deaths within 2 or 30 days from specimen collection. A time-dependent Cox model was applied to evaluate the impact of patient characteristics and causative pathogens on the hazard for death at different time points.ResultsA total of 173,715 BSI were identified; 22,474 (12.9%) were fatal within 30 days and, of these, 6,392 (28.4%) occurred within 2 days (7.9 deaths/100,000 population). The 2-day case fatality rate of HA-BSI was higher than that of CA-BSI (5.4% vs 3.0%). Patients who died within 2 days were older than those alive on day 3 (76 vs 70 years) and had more severe comorbidities. Compared with other BSI, infections leading to death within 2 days were more often polymicrobial (11.8% vs 6.3%) and caused by Pseudomonas aeruginosa (6.2% vs 2.0%), fungi (2.9% vs 1.4%) and multidrug-resistant (MDR) pathogens (2.2% vs 1.8%), which were also predictors of death within 2 days in the model.ConclusionsOverrepresentation of polymicrobial, fungal, P. aeruginosa and MDR aetiology among BSI leading to early death is challenging concerning the initial antimicrobial treatment. Our findings highlight the need for active prevention and prompt recognition of BSI and appropriate antimicrobial treatment.

BACKGROUND: CCAAT enhancer-binding protein epsilon (C/EBPε) is a transcription factor involved in late myeloid lineage differentiation and cellular function. The only previously known disorder linked to C/EBPε is autosomal recessive neutrophil-specific granule deficiency leading to severely impaired neutrophil function and early mortality. OBJECTIVE: The aim of this study was to molecularly characterize the effects of C/EBPε transcription factor Arg219His mutation identified in a Finnish family with previously genetically uncharacterized autoinflammatory and immunodeficiency syndrome. METHODS: Genetic analysis, proteomics, genome-wide transcriptional profiling by means of RNA-sequencing, chromatin immunoprecipitation (ChIP) sequencing, and assessment of the inflammasome function of primary macrophages were performed. RESULTS: Studies revealed a novel mechanism of genome-wide gain-of-function that dysregulated transcription of 464 genes. Mechanisms involved dysregulated noncanonical inflammasome activation caused by decreased association with transcriptional repressors, leading to increased chromatin occupancy and considerable changes in transcriptional activity, including increased expression of NLR family, pyrin domain-containing 3 protein (NLRP3) and constitutively expressed caspase-5 in macrophages. CONCLUSION: We describe a novel autoinflammatory disease with defective neutrophil function caused by a homozygous Arg219His mutation in the transcription factor C/EBPε. Mutated C/EBPε acts as a regulator of both the inflammasome and interferome, and the Arg219His mutation causes the first human monogenic neomorphic and noncanonical inflammasomopathy/immunodeficiency. The mechanism, including widely dysregulated transcription, is likely not unique for C/EBPε. Similar multiomics approaches should also be used in studying other transcription factor-associated diseases.

Skin and skin structure infection (SSSI) is classified as complicated (cSSSI) if it involves deep subcutaneous tissue or requires surgery. Factors associated with blood culture sampling and bacteremia have not been established in patients with cSSSI. Moreover, the benefit of information acquired from positive blood culture is unknown. The aim of this study was to address these important issues. In this retrospective population-based study from two Nordic cities, a total of 460 patients with cSSSI were included. Blood cultures were drawn from 258 (56.1%) patients and they were positive in 61 (23.6%) of them. Factors found to be associated with more blood culture sampling in multivariate analysis were diabetes, duration of symptoms shorter than 2 days and higher C-reactive protein (CRP) level. Whereas factors associated with less frequent blood culture sampling were peripheral vascular disease and a surgical wound infection. In patients from whom blood cultures were taken, alcohol abuse was the only factor associated with culture positivity, as CRP level was not. Patients with a positive blood culture had antibiotic streamlining more often than non-bacteremic patients. A high rate of blood culture positivity in patients with cSSSI was observed. Factors related to more frequent blood culture sampling were different from those associated with a positive culture.

Treatment of infective endocarditis (IE) should be initiated promptly. This might hamper the chances to identify the causative organism in blood cultures. Microbiological sampling of infected valve in patients undergoing surgery might identify the causative organism. The impact of pre-operative antimicrobial treatment on the yield of valve samples is not known. This study evaluated the impact of the duration of the pre-operative antibiotic treatment on valve culture and 16S rRNA PCR findings from resected endocardial samples. Patients meeting the modified Duke criteria of definite or possible IE and undergoing valve surgery due to IE during 2011-2016 were included from Southern Finland. Eighty-seven patients were included. In patients with shorter than 2 weeks of pre-operative antimicrobial treatment, PCR was positive in 91% (n = 42/46) and valve culture in 41% (n = 19/46) of cases. However, in patients who had 2 weeks or longer therapy before operation, PCR was positive in 53% (n = 18/34) and all valve cultures were negative. In 14% of patients, PCR had a diagnostic impact. In blood-culture negative cases (n = 13), PCR could detect the causative organism in ten patients (77%). These included five cases of Bartonella quintana, one Tropheryma whipplei, and one Coxiella burnetii. Long pre-operative antimicrobial treatment was shown to have a negative impact on microbiological tests done on resected endocardial material. After 2 weeks of therapy, all valve cultures were negative, but PCR was positive in half of the cases. PCR aided in diagnostic work-up, especially in blood culture negative cases.

Few studies covering all patient groups and specialties are available regarding the outcome of nosocomial bloodstream infections (BSI). We analyzed the role of patient characteristics and causative pathogens of nosocomial BSIs reported by the hospitals participating in national surveillance in Finland during 1999-2014, in terms of outcome, with particular interest in those leading to death within 2 days (i.e. early death). National nosocomial BSI surveillance was laboratory-based and hospital-wide. Data on nosocomial BSIs was collected by infection control nurses, and dates of death were obtained from the national population registry with linkage to national identity codes. A total of 17,767 nosocomial BSIs were identified; 557 BSIs (3%) were fatal within 2 days and 1150 (6%) within 1 week. The 1-month case fatality was 14% (2460 BSIs), and 23% of the deaths occurred within 2 days and 47% within 1 week. The patients who died early were older than those who survived > 28 days, and their BSIs were more often related to intensive care. Gram-positive bacteria caused over half of the BSIs of patients who survived, whereas gram-negative bacteria, especially Pseudomonas aeruginosa, caused more often BSIs of patients who died early, and fungi BSIs of patients who died within 1 week. A significant portion of patients with nosocomial BSIs died early, which underlines the importance of rapid recognition of BSI. Hospital-wide surveillance data of causative pathogens can be utilized when composing recommendations for empiric antimicrobial treatment in collaboration with clinicians, as well as when promoting infection prevention.

This paper describes an action framework for countries with low tuberculosis (TB) incidence (<100 TB cases per million population) that are striving for TB elimination. The framework sets out priority interventions required for these countries to progress first towards "pre-elimination" (<10 cases per million) and eventually the elimination of TB as a public health problem (less than one case per million). TB epidemiology in most low-incidence countries is characterised by a low rate of transmission in the general population, occasional outbreaks, a majority of TB cases generated from progression of latent TB infection (LTBI) rather than local transmission, concentration to certain vulnerable and hard-to-reach risk groups, and challenges posed by cross-border migration. Common health system challenges are that political commitment, funding, clinical expertise and general awareness of TB diminishes as TB incidence falls. The framework presents a tailored response to these challenges, grouped into eight priority action areas: 1) ensure political commitment, funding and stewardship for planning and essential services; 2) address the most vulnerable and hard-to-reach groups; 3) address special needs of migrants and cross-border issues; 4) undertake screening for active TB and LTBI in TB contacts and selected high-risk groups, and provide appropriate treatment; 5) optimise the prevention and care of drug-resistant TB; 6) ensure continued surveillance, programme monitoring and evaluation and case-based data management; 7) invest in research and new tools; and 8) support global TB prevention, care and control. The overall approach needs to be multisectorial, focusing on equitable access to high-quality diagnosis and care, and on addressing the social determinants of TB. Because of increasing globalisation and population mobility, the response needs to have both national and global dimensions.

Pneumonia is recognised in patients suffering from acute cough or deteriorated general condition. Patients with acute cough without pneumonia-related symptoms or clinical findings do not benefit from antimicrobial treatment. Those with suspected or confirmed pneumonia are treated with antibiotics, amoxicillin being the first choice. Most patients with pneumonia can be treated at home. Those with severe symptoms are referred to hospital. Patients are always encouraged to contact his/her physician if the symptoms worsen or do not ameliorate within 2-3 days. Patients aged 50 years or older and smokers are controlled by thoracic radiography in 6-8 weeks.

BACKGROUND: Alcoholism associates with increased Staphylococcus aureus bacteremia incidence and mortality. The objective was to compare disease progression, treatment and prognosis of Staphylococcus aureus bacteremia in alcoholics versus non-alcoholics. METHODS: The study design was a multicenter retrospective analysis of methicillin-sensitive Staphylococcus aureus bacteremia with 90-day follow-up. Patients were stratified as alcoholics or non-alcoholics based on electronic health record data. Altogether 617 Staphylococcus aureus bacteremia patients were included of which 83 (13%) were alcoholics. RESULTS: Alcoholics, versus non-alcoholics, were younger, typically male and more commonly had community-acquired Staphylococcus aureus bacteremia. No differences in McCabe´s classification of underlying conditions was observed. Higher illness severity at blood culture sampling, including severe sepsis (25% vs. 7%) and intensive care unit admission (39% vs. 17%), was seen in alcoholics versus non-alcoholics. Clinical management, including infectious disease specialist (IDS) consultations and radiology, were provided equally. Alcoholics, versus non-alcoholics, had more pneumonia (49% vs. 35%) and fewer cases of endocarditis (7% vs. 16%). Mortality in alcoholics versus non-alcoholics was significantly higher at 14, 28 and 90 days (14% vs. 7%, 24% vs. 11% and 31% vs. 17%), respectively. Considering all prognostic parameters, male sex (OR 0.19, p = 0.021) and formal IDS consultation (OR 0.19, p = 0.029) were independent predictors of reduced mortality, whereas ultimately or rapidly fatal comorbidity in McCabe´s classification (OR 12.34, p < 0.001) was an independent predictor of mortality in alcoholics. CONCLUSIONS: Alcoholism deteriorates Staphylococcus aureus bacteremia prognosis, and our results suggests that this is predominantly through illness severity at bacteremia onset. Three quarters of Staphylococcus aureus bacteremia patients we studied had identified deep infection foci, and of them alcoholics had significantly less endocarditis but nearly half of them had pneumonia.

BACKGROUND: Non-tuberculous mycobacteria (NTM) cause disease in healthy and immunocompromised patients. The American Thoracic Society (ATS) 2007 diagnostic criteria were devised to distinguish NTM disease from airway colonization. The aim of this study was to evaluate the prognostic value of the ATS criteria. METHODS: In a 4-y follow-up study that ended on 8 June 2006, we retrospectively analyzed the symptoms, underlying diseases, and mortality of 120 adult non-HIV patients with NTM culture findings obtained between 1990 and 1998. We categorized the patients according to the 2007 ATS NTM case definition into positive and negative groups. RESULTS: Only 61/120 patients (51%) fulfilled the ATS criteria for NTM disease. As compared to ATS-negative subjects, the ATS-positive group showed lower age, a higher proportion of females, and fewer fatal underlying diseases. Among ATS-negative subjects, 46/59 (78%) did not fulfil the microbiological criteria and 43/59 (73%) did not fulfil the radiological criteria. Mycobacterium avium complex (MAC) comprised 61% of isolations in the ATS-positive and 47% in the ATS-negative group (p = 0.15). No significant difference in median survival time was found between the groups: ATS-positive 7.4 y (95% confidence interval (CI) 0.2-14.6) and ATS-negative 5.3 y (95% CI 3.0-7.6). No significant difference was found in symptoms except fatigue, which was more common in the ATS-positive (56% vs 37%, p = 0.04). Symptoms lasted for less than a year in 48%, which suggests a more rapid disease progression than has previously been reported. CONCLUSIONS: The fulfillment of ATS criteria was poorly associated with any difference in prognosis, and based on our findings would be a poor prognostic marker.

A healthcare worker sought medical advice after four days of fever, muscle pains, occipital headache and blocked ears, and was diagnosed with a high CRP level and blood bullae in the outer ear canal. In addition, skin rash appeared during hospital care, and the fever did not seem to go down upon treatment with broad-spectrum antibiotics, during which the CRP rose to a level of 413 mg/L at the highest. Haemorragic bullous otisis was confirmed diagnosis caused by Mycoplasma Pneumoniae.

A seventyseven-year old woman had a history of osteomyelitis in the 1940s. Now, she was investigated for an antibiotic resistant fever. An unusual infection, an autoimmune disease or a malignancy was suspected. In the CT scan a mediastinal mass was detected and a mediastinoscopy was performed. Histology revealed a granulomatous infection but a tuberculous infection was ruled out. A favourable response to ordinary antibiotics was gained and the diagnosis of tularemia was confirmed by a serologic test.

Objective: Prevention of healthcare-associated infective endocarditis (HAIE) is based on characterization of underlying factors. Our object was to describe the source of infection, microbiological etiology, and healthcare-related risk factors for HAIE. Design: Retrospective population-based study. Patients: Adult patients diagnosed with HAIE during 2013-2017 who resided in the study area in Southern Finland with adult population of 0.9 million. Results: Ninety-five HAIE episodes were included. Ten episodes were related to cardiac surgery. Of the remaining 85 episodes, 11 were classified as nosocomial (ie, acquired and diagnosed during ongoing hospitalization) and 74 as non-nosocomial HAIE. Staphylococcus aureus caused 45% of nosocomial episodes, but only 16% of non-nosocomial episodes (P = 0.039). Most common sources of infection in non-nosocomial HAIE were previous hospitalization (24%), dialysis (18%), and urologic procedures (15%). Enterococcus spp. caused 23% of non-nosocomial HAIE, and more than half of them were associated with urologic or gastrointestinal procedures. Two-thirds of the non-nosocomial HAIE patients had recent hospitalization or invasive procedure. We counted previous healthcare-related risk factors for IE and those who had two or more of them had higher in-hospital and one-year mortality. Conclusion: Our study indicates the importance of non-nosocomial acquisition of HAIE and S. aureus as the major pathogen in nosocomial episodes. Enterococcal infections dominate in non-nosocomial cases and further studies are needed to identify patients at risk for enterococcal IE after urological or gastrointestinal procedure.
RESUMEN
Objective: Hospital-acquired (HA) COVID-19 infections are known to increase morbidity and mortality. The aim of this study was to investigate the incidence and outcome of HA COVID-19 in different specialties across the wards in 18 hospitals belonging to the Helsinki University Hospital (HUH) responsible for secondary and tertiary care of a population of 1.8 million. Design: Retrospective population-based cohort study. Setting: Secondary and tertiary care hospitals. Patients: Inpatients with HA COVID-19 infection. Methods: The HA COVID-19 infections with patient characteristics were retrospectively searched from HUH patient database from 1st October 2021 to 31st March 2022. All positive SARS-CoV-2 nucleic acid amplification tests (NAATs) from any ward were reviewed. The COVID-19 infection was classified as HA if a notification of HA infection was done or SARS-CoV-2 NAAT was positive ≥6 days after hospital admission or medical records revealed a known exposure for COVID-19 during hospital stay. Results: 177 HA COVID-19 infections were retrieved with an incidence of 0.55 per 1000 patient days. Of these patients, 71 (40%) were treated in medicine, 52 (29%) in operative, and 54 (31%) in psychiatric wards, leading to incidences of 0.51, 0.39, and 1.10 per 1,000 patient days, respectively. In association with COVID-19, 16 (23%) in medicine, 3 (6%) in operative, and 1 (2%) patient in psychiatric wards deceased. Of the deceased patients, 16 (80%) had received at least one COVID-19 vaccine. Conclusions: Hospital-acquired COVID-19 infections in omicron era were related to high mortality, especially among patients in medicine wards who also had good vaccination coverage.
RESUMEN
Mycoplasma pneumoniae causes respiratory infections, but in as many as one out of four of those having contracted the infection symptoms may appear elsewhere, sometimes without preceding respiratory symptoms. Among these, symptoms of central nervous system origin are most the common. Specific diagnosis of the infection is demanding, and is mainly based on serology. Application of nucleic acid detection tests might lead to an earlier diagnostics. Efforts associated with diagnosis should mainly be targeted at detecting epidemics as well as diagnosing patients with severe or abnormal symptoms during the epidemy.

BACKGROUND: Male sex predicts case-fatality in SARS-CoV-2 (COVID-19) - a phenomenon linked to systemic inflammation. We compared sex-related associations of inflammation parameters and outcome in a population-based setting with low case-fatality prior to wide use of immunosuppressives. METHODS: A population-based quality registry with laboratory-confirmed COVID-19 cases of specialized hospitals of the Capital Province of Finland were analysed to compare inflammatory parameters by sex during the first COVID-19 wave February-June 2020. RESULTS: Altogether, 585 hospitalized patients (54% males) were included. Males required more often intensive care unit (ICU) treatment (26.9 vs. 17.5%) and had higher 90-d case-fatality (14.9 vs. 7.8%) compared with females. Highest association with case-fatality in males was seen for high neutrophil counts (median; interquartile range) (8.70; 7.10-9.10 vs. 5.60; 3.90-7.80) (E9/l), low monocyte (0.50; 0.20-1.50 vs. 0.70; 0.50-0.90) (E9/l) and lymphocyte (0.90; 0.70-1.40 vs. 1.50; 1.10-2.00) (E9/l) counts, and high levels of d-dimer (3.80; 1.80-5.30 vs. 1.10; 0.60-2.75) (mg/l) and C-reactive protein (CRP) (190; 85.5-290 vs. 77.0; 49.0-94.0) (mg/l). In females, low lymphocyte (0.95; interquartile range 0.60-1.28 vs. 1.50; 1.10-2.00) (E9/l) and thrombocyte counts (196; 132-285 vs. 325; 244-464) (E9/l) and high CRP values (95.0; 62.0-256 vs. 66.0; 42.5-89.0) (mg/l) were associated with case-fatality. In multivariable analysis for males, lymphocyte cut-off 0.85 (E9/l) (OR 0.02; 95% CI 0.002-0.260), d-dimer cut-off 1.15 (mg/l) (OR 7.29; 1.01-52.6) and CRP cut-off 110 (mg/l) (OR 15.4; 1.87-127) were independently associated with case-fatality. In female multivariable analysis, CRP cut-off 81 (mg/l) (OR 7.32; 1.44-37.2) was the only inflammatory parameter associated with case-fatality. CONCLUSIONS: COVID-19 results in higher inflammation parameter levels in male vs. female patients irrespective of outcome. This study suggests that low lymphocyte, high d-dimer and high CRP cut-off values may serve as potential markers for risk stratification in male patients.

Our objective was to study the consumption of healthcare services and antibiotics in patients with suspicion of disseminated Lyme borreliosis (LB) before and after consultation of an infectious disease specialist. We evaluated retrospectively all presumed disseminated LB patients (n = 256) with a referral to the Department of Infectious Diseases (DID) in Helsinki University Hospital in 2013. Medical records from all healthcare providers in the area were reviewed and the number of physician contacts because of symptoms leading to LB suspicion and antimicrobial purchases were calculated 1 year before and after consultation or treatment at the DID. Patients were divided into three groups according to certainty of LB: unlikely, possible or probable/definite LB. The number of healthcare contacts 1 year before referral was higher among 121 patients with unlikely LB (6; interquartile range [IQR] 3-10), than 65 possible (4; IQR 2.5-7; p = 0.018) or 66 probable/definite LB patients (4; IQR 2.8-7; p = 0.010). The median number of contacts to healthcare during one year after consultation or treatment was 3 (IQR 0.5-7), 1 (IQR 0-3) and 0.5 (IQR 0-2.3), respectively, with a statistically significant difference between the groups (p<0.001). Antibiotics were purchased by 151 (60%) patients one year before referral and by 127 (50%) patients year after consultation or treatment at DID without statistically significant difference between groups with different LB certainty. These antibiotic purchases do not include the treatments prescribed by infectious disease specialists. In the case of 27 patients, an antimicrobial treatment was recommended in the consultation reply. In conclusion, patients with unlikely LB used more healthcare services than patients with possible or probable/definite LB. Antimicrobial consumption was similar between groups of different LB certainty.

OBJECTIVE: Bacteria entering the bloodstream through oral mucosa cause bacteremia, which can lead to septic or distant infections. The underlying factors and need for dental treatment in patients referred for oral examination because of septic infection were investigated. It was expected that general diseases and poor socioeconomic status of patients would increase the risk of bacteremia. METHOD AND MATERIALS: This descriptive retrospective study included patients (N = 128) referred from medical clinics of the Helsinki University Hospital (HUH), during 2012 to 2017, to the Department of Oral and Maxillofacial Diseases due to bacteremia suspected to be of oral origin. Data were extracted from medical and dental records according to the World Health Organization International Classification of Diseases (ICD-10) for systemic or remote infections. Different groups were formed using modified Skapinakis classification for socioeconomic status (SES), from I (high) to V (low). Underlying medical conditions were retrieved according to McCabe classification: healthy, nonfatal, ultimately fatal, and rapidly fatal diseases. The data were analyzed using the statistical software package SPSS (IBM). RESULTS: Patients were referred most often from the Departments of Infectious Diseases and Internal Medicine. Because of infection, 12 patients needed aortic or mitral valve operations. Many of the patients were intravenous drug users. However, the majority of patients presented McCabe class I, indicating no systemic disease. The main SES was intermediate III. Tooth extraction was the principal mode of treatment. No demographic background variables were identified to explain increase of the risk for bacteremia except that most patients were men with untreated dental problems. CONCLUSIONS: Contrary to the authors' expectation, poor SES and underlying diseases did not seem to link to the outcome. However, untreated dental infections present an evident risk for life-threatening septic complications also in generally healthy individuals.

BACKGROUND: The long-term sequelae after COVID-19 are not yet fully known. Our aim was to evaluate subjective symptoms and quality of life in Finnish hospitalized COVID-19 patients at six months follow-up. METHODS: Hospitalised adult patients with laboratory-confirmed SARS-CoV-2 infection from March to June 2020 were recruited. We conducted a survey on demographics and comorbidities, ten specific symptoms, and a RAND-36 quality of life questionnaire six months after hospital discharge. We collected clinical data manually from medical records. RESULTS: 101 patients (54 male) out of 246 invited completed the survey. Their median age was 60 years, and the mean hospital length of stay was 15 d. Most patients (90%) experienced symptoms, the most common of which were tiredness (88%), fatigue (79%), sleeping problems (76%), and dyspnoea (70%). In regard to gender, women showed a shorter time of hospitalization (p = .048) and lower peak flow of supplementary oxygen (p = .043). Women reported more frequently dyspnoea, fatigue, tiredness, sleeping problems, and mood problems (p = .008-.033), and a lower quality of life in seven of eight dimensions (p < .001-.015). Five explanatory variables for the reduced quality of life were identified in multivariate analysis: age, female sex, BMI, sleep apnoea, and duration of mechanical ventilation. Of the patients who worked full-time before COVID-19, 11% had not returned to work. CONCLUSIONS: Most patients experienced symptoms six months after hospital discharge. Women reported more symptoms and a lower quality of life than men. These findings highlight the differences in recovery between men and women and call for active rehabilitation of COVID-19 patients.

BACKGROUND: Over the past two decades, livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) has become widely prevalent in pig production in Europe. The carriage status of LA-MRSA is known to vary among individual pigs, but bacterial load in pigs has rarely been studied. We assessed the quantity of LA-MRSA in nasal and skin samples of pigs and investigated the genetic diversity of the strains together with sequenced strains from national surveillance and pathology samples from the Finnish Food Authority. On two farms with assumed MRSA-positive status, farm 1 and farm 2, 10 healthy pigs were sampled three times during 2 weeks from the nares and skin (study A). On farm 1, 54 additional pigs were sampled and from confirmed MRSA-positive animals, 10 were randomly selected and transported to a clean, controlled environment for further sampling (study B). From the samples taken on farms 1 and 2 and in the controlled environment, MRSA was isolated both by direct plating and enrichment on selective media. spa types, multilocus sequence types, staphylococcal cassette chromosome mec types, resistance and virulence genes were determined. Core genome multilocus sequence typing (cgMLST) analysis was performed, including the sequences deriving from the surveillance/pathology samples from the Finnish Food Authority. RESULTS: All pigs on farm 1 carried LA-MRSA in the nares at all three time points and five pigs on farm 2 at one time point. Nasal quantity varied between 10 and 103 CFU/swab and quantity on the skin between 10 and 102 CFU/swab. In the controlled environment, MRSA was detected in at least one of the nasal samples from each animal. spa type t034 was predominant. cgMLST showed one cluster with minimum allele differences between 0 and 11. CONCLUSIONS: The study shows predominantly low-level carriage (< 103 CFU/swab) of LA-MRSA on farms. In the controlled environment we observed a decline in nasal carriage but constant skin carriage. cgMLST showed that strains of spa type t034 are closely related at the national level.
