A human immunodeficiency virus-1 (HIV-1)-positive male undergoing antiretroviral therapy was diagnosed with an axillary lymph node abscess caused by Corynebacterium ulcerans, and an environmental survey revealed that the patient's cat as the source of infection.

A health emergency situation occurred in Bulgaria in 2007 when positive rabies cases were notified in Sofia district in the central-western part of the country, suggesting a southward spread of the disease for the first time in the last 10 years. Phylogenetic analysis on 49 isolates sampled between 2009 and 2011 showed, for the first time, evidence of the existence of NEE and D clustered lineages in Bulgaria. Their geographical distribution clearly reveals the permeability of natural barriers, as already suggested by the disease spread that occurred across the Balkan mountain range in 2007. The monitoring and passive surveillance programmes conducted since the first 2009 oral vaccination campaign, the spatio-temporal evolution of the disease in the country since 2007, and the need for further investigation of the role of jackals in virus dispersion are discussed.

Data obtained from genitourinary medicine clinics through a comprehensive surveillance system were used in a Bayesian mixed-effects Poisson regression model to explore socio-demographic individual and ecological risk factors for gonorrhoea in London, as well as its spatial clustering. The spatial analysis was performed at the Middle-layer Super Output Area level (median population size 7200). A total of 12452 individuals were diagnosed during the 2-year study period (2009–2010). The study confirmed the presence of ‘core areas’ of high incidence, and identified ‘core’ high-risk groups, in particular young adults (16–29 years), males, black Caribbeans and more deprived areas. The individual (age, sex, ethnicity) and area-level (deprivation, teenage pregnancies, students) model covariates accounted for 48% of the variance. Most of the remaining variance was explained by the spatial effect, thus capturing other spatially distributed factors associated with gonorrhoea, such as local sexual networks. These findings will be useful in identifying areas for targeted interventions, such as STI testing and health promotion.

It is unknown which intervention strategies are used or effective to increase influenza vaccine uptake by healthcare workers (HCWs) in acute hospitals in England. We undertook a survey in acute hospitals, described strategies employed from 2008 to 2012 and used multivariable binomial regression to identify those effective. Eighty out of 166 trusts responded and reported 25 strategies. Every intervention showed increased use: peer vaccination from 3·8% to 38·8% (+921%); educational DVDs from 3·8% to 22·5% (+492%); Twitter from 2·5% to 12·5% (+400%) and Facebook from 1·3% to 6·3% (+384%). Peer vaccination increased uptake by 7·3% [95% confidence interval (CI) 1·1–13·6, P = 0·02] overall; educational DVDs by 9·7% overall (95% CI 1·8–17·6, P = 0·02), 11·9% in non-doctor, non-nurse HCWs (95% CI 0·9–22·8, P = 0·03). For doctors, using a champion doctor increased uptake by 17·8% (95% CI 7·6–28·0, P < 0·01). No intervention increased uptake by nurses. Increasing uptake requires multi-intervention strategies targeted at different HCW groups.

In recent years the number of pregnant women susceptible to rubella has increased markedly. In the West Midlands the proportion has risen from 1·4% in 2004 to 6·9% in 2011. Locally, the proportion of non-immune women ranges from 1·6% in those born prior to 1976 to 17·8% in those born since 1986. The latter group comprises those given MMR in their second year with no further booster doses. The number of non-immune women will continue to rise as a consequence of low MMR uptake in the late 1990s. Repeat testing of samples with values <10 IU/ml and the need to vaccinate women postnatally have increased the workload of laboratory and maternity units. Screening for rubella in pregnancy has no advantages for the current pregnancy and it may be time to review the universal MMR vaccination programme which in turn would remove the need for continuing this practice.

To explore the specificities of Escherichia coli bacteraemia in the elderly, the demographic, clinical and bacteriological characteristics and in-hospital mortality rate of ‘young’ (18–64 years, n = 395), ‘old’ (65–79 years, n = 372) and ‘very old’ (⩾80 years, n = 284) adult patients of the multicentre COLIBAFI cohort study were compared. Clinical and bacteriological risk factors for death were jointly identified by logistic regression and multivariate analysis within each group. ‘Young’ and ‘old’ patients had more comorbidities than ‘very old’ patients (comorbidity score: 1·5 ± 1·3 and 1·6 ± 1·2 vs. 1·2 ± 1·2, respectively; P < 0·001), and were more frequently nosocomially infected (22·3% and 23·8% vs. 8·8%, respectively; P < 0·001). ‘Old’ patients had the poorest prognosis (death rate: 16·4% vs.10·4% for ‘young’ and 12·0% for ‘very old’ patients, respectively; P = 0·039). Risk factors for death were age group-specific, suggesting a host–pathogen relationship evolving with age.

Maternal infection in pregnancy is a known risk factor for adverse pregnancy outcome, and a number of zoonotic pathogens may constitute a risk to pregnant women and their fetuses. With animal contact as a proxy for the risk of zoonotic infection, this study aimed to evaluate pregnancy outcome in women with self-reported occupational or domestic contact with livestock compared to pregnant women without such contact. The Danish National Birth Cohort collected information on pregnancy outcome from 100 418 pregnant women (1996–2002) from which three study populations with occupational and/or domestic exposure to livestock and a reference group of women with no animal contact was sampled. Outcome measures were miscarriage, very preterm birth (before gestational week 32), preterm birth (before 37 gestational weeks), small for gestational age (SGA), and perinatal death. Adverse reproductive outcomes were assessed in four different exposure groups of women with occupational or domestic exposure to livestock with no association found between exposure to livestock and miscarriage, preterm birth, SGA or perinatal death. These findings should diminish general occupational health concerns for pregnant women with exposures to a range of different farm animals.

Daptomycin-non-susceptible enterococci (DNSE) are emerging pathogens. We have previously reported de novo DNSE isolates in patients with agricultural activities and exposure to livestock. We studied the geographical distribution of the residencies of 34 patients with DNSE infections described in a tertiary centre over a 5-year period in an effort to explore the association between patients’ residential locations and agricultural and farm lands. Nine patients had no prior exposure to daptomycin (de novo) and seven of these lived in areas with animal or crop operations. Of those living near an animal or crop operation, the mean number of operations in the proximity of the residence of patients with daptomycin-exposed DNSE was 13·8 (range 1–67) compared to 98·6 (3–529) for those patients with de novo DNSE (P = 0·0486). These data are consistent with previous reports that the transport of daptomycin resistance genes between animals and humans may be a possible mechanism for development of de novo daptomycin resistance in enterococci.

Vibrio vulnificus (Vv) can result in severe disease. Although pre-existing liver disease is a recognized risk factor for serious infection, the relative importance of other comorbidities has not been fully assessed. We analysed reports of Vv infections submitted to CDC from January 1988 to September 2006 in order to assess the role of pre-existing conditions contributing to severe outcomes. A total of 1212 patients with Vv infection were reported. Only patients with liver disease [adjusted odds ratio (aOR) 5·1)] were more likely to become septic when exposure was due to contaminated food. Patients with liver disease (aOR 4·1), a haematological disease (aOR 3·2), or malignancy (aOR 3·2) were more likely to become septic when infection was acquired via a non-foodborne exposure. As such, patients with these pre-existing medical conditions should be advised of the risk of life-threatening illness after eating undercooked contaminated seafood or exposing broken skin to warm seawater.

Non-tuberculous mycobacteria are increasingly described as infectious agents in immunocompromised patients. A 17-year-old male patient suffering from secondary non-Hodgkin's lymphoma and treated with chemotherapeutic agents was admitted to hospital due to pleuropneumonia. Mycobacterium neoaurum was cultured repeatedly from his sputum and, Mycobacterium avium subsp. avium (M. a. avium) was detected by IS901 qPCR from detached fragments of his intestinal mucosa. We attempted to determine the possible sources of infection by analysing environmental samples from the closed oncology unit and conventional unit in the hospital, and from the patient's home residence and places which he frequented. The environment of the patient harboured mycobacteria (41 isolates in total); however, M. neoaurum was not recovered. M. a. avium was detected by qPCR in the environmental samples from a small flock of hens kept by his neighbour. Although it was not confirmed by DNA fingerprinting methods, the M. a. avium infection could have been acquired through the eating of incompletely cooked eggs.
