Geographical and temporal distribution of multidrug-resistant Infantis in Europe and the Americas.

Recently emerged Infantis strains carrying resistance to several commonly used antimicrobials have been reported from different parts of the globe, causing human cases of salmonellosis and with occurrence reported predominantly in broiler chickens. Here, we performed phylogenetic and genetic clustering analyses to describe the population structure of 417 Infantis originating from multiple European countries and the Americas collected between 1985 and 2019. Of these, 171 were collected from 56 distinct premises located in England and Wales (E/W) between 2009 and 2019, including isolates linked to incursions of multidrug-resistant (MDR) strains from Europe associated with imported poultry meat.

Impact of Opt-Out Therapy Appointments on Resident Physicians' Mental Health, Well-Being, Stigma, and Willingness to Engage.

Health care professionals report higher levels of mental health symptoms, pandemic-related stress, personal health concerns, and reduced proactive coping, especially in recent years marked by the COVID-19 pandemic. As physician utilization rates of mental health and well-being services remain low, the need for preemptive care is crucial. The present study sought to ascertain satisfaction, value, and attitude toward future mental health services among resident physicians.

Efficacy of Five Disinfectant Products Commonly Used in Pig Herds against a Panel of Bacteria Sensitive and Resistant to Selected Antimicrobials.

The growing threat of antimicrobial resistance worldwide has led to an increasing concern in the human, veterinary, and environmental fields, highlighting the need for strategies to effectively control bacterial contamination. Correct biosecurity practices, including the appropriate use of disinfectants, play a crucial role in controlling bacterial contamination. This study aimed to verify whether the recommended concentrations defined according to the Defra General Orders concentration (GO, published by the UK Department for Environment, Food and Rural Affairs' disinfectant-approval scheme) of five commercial disinfectant preparations (peroxygen-based, phenol-based, two halogen-releasing agents, and glutaraldehyde/quaternary ammonium compound-based; disinfectants A to E, respectively) were sufficient to inhibit growth and inactivate selected bacterial strains, including some that carry known phenotypic patterns of multidrug resistance.

A systematized review and qualitative synthesis of potential risk factors associated with the occurrence of non-O157 Shiga toxin-producing Escherichia coli (STEC) in the primary production of cattle.

Human infection with Shiga toxin-producing Escherichia coli (STEC) causes an estimated 2.8 million cases of acute illness worldwide each year. Serogroup O157 is the most commonly diagnosed STEC in humans, but cases linked to non-O157 STEC serogroups have increased recently due to increased surveillance and improvements to detection methods.

In-depth farm investigations and an exploratory risk factor analysis for the presence of Salmonella on broiler farms in Great Britain.

Salmonella is a major cause of foodborne illness across Europe but there has been little recent research on its control in broiler production in Great Britain. Investigations of Salmonella presence on 20 broiler farms and a separate exploratory risk factor analysis involving 36 Salmonella-positive farms and 22 Salmonella-negative farms were carried out to investigate Salmonella contamination and control on broiler farms in Great Britain. Sources of Salmonella persistence on farm and potential risk factors for on-farm contamination were identified, enabling provision of up-to-date advice on Salmonella control to farmers.

Pilot Investigation of Anti- Antibodies in Oral Fluids from Typhimurium Vaccinated and Unvaccinated Swine Herds.

Oral fluid (OF) can be a simple, cheap and non-invasive alternative to serum or meat juice for the diagnosis and surveillance of important pathogens in pigs. This study was conducted on four Typhimurium-positive farrow-to-finish pig farms: two -vaccinated (V) and two non-vaccinated (NV). Gilts and sows in the V farms were vaccinated with a live, attenuated vaccine prior to farrowing.

Control of and Pathogenic Contamination of Animal Feed Using Alternatives to Formaldehyde-Based Treatments.

This study compared a novel non-formaldehyde combination product developed for pathogen control in animal feed Finio (A), with a panel of three commonly used organic acid feed additive products: Fysal (B), SalCURB K2 (C) and Salgard (D). Products were evaluated for their ability to reduce Typhimurium DT104 and avian pathogenic in poultry feed. A commercial layer-hen mash was treated with each product and then mixed with feed previously contaminated (via inoculated meat and bone meal) with either or After 24 hours at room temperature, 10 replicate samples were taken from each preparation and plate counts were performed using a selective agar.

Determining the therapist's contribution in therapist multicultural competence process and outcome.

Efforts to help therapists improve their multicultural competence (MCC) rely on measures that can distinguish between different levels of competence. MCC is often assessed by asking clients to rate their experiences with their therapists. However, differences in client ratings of therapist MCC do not necessarily provide information about the relative performance of therapists and can be influenced by other factors including the client's own characteristics.

Covid-19 lockdowns, income distribution, and food security: An analysis for South Africa.

Absent vaccines and pharmaceutical interventions, the only tool available to mitigate its demographic effects is some measure of physical distancing, to reduce contagion by breaking social and economic contacts. Policy makers must balance the positive health effects of strong distancing measures, such as lockdowns, against their economic costs, especially the burdens imposed on low income and food insecure households. The distancing measures deployed by South Africa impose large economic costs and have negative implications for the factor distribution of income.

Field investigations of multidrug-resistant Infantis epidemic strain incursions into broiler flocks in England and Wales.

Infantis is a major public health concern and has become established in the broiler sector in some European countries, as well as globally, and is frequently multidrug resistant (MDR). Three broiler farms in England and Wales, which had incursions of MDR Infantis between 2013 and 2017, were investigated longitudinally. The company feed mill and two associated hatcheries were intensively sampled.

Correlation of Anti- Antibodies Between Serum and Saliva Samples Collected From Finisher Pigs.

Saliva samples obtained by using absorptive devices, can provide an alternative diagnostic matrix to serum for monitoring disease status in pigs. The aim of this study was to investigate the correlation of anti- antibodies between serum and saliva samples collected from pigs. Twenty individual paired serum and saliva samples were collected from a single farm.

Identification of Genetic Features for Attenuation of Two Enteritidis Vaccine Strains and Differentiation of These From Wildtype Isolates Using Whole Genome Sequencing.

Enteritidis is a major cause of salmonellosis worldwide and more than 80% of outbreaks investigated in Europe have been associated with the consumption of poorly cooked eggs or foods containing raw eggs. Vaccination has been proven to be one of the most important measures to control Enteritidis infections in poultry farms as it can decrease colonization of the reproductive organs and intestinal tract of laying hens, thereby reducing egg contamination. Differentiation of live vaccine from field or wild type .

Role of wild birds and environmental contamination in the epidemiology of Salmonella infection in an outdoor pig farm.

Foodborne outbreaks caused by Salmonella are often attributed to the pork consumption. Salmonella contamination of retail pork is directly linked to the Salmonella prevalence on farm. In UK, approximately 40% of breeding pigs are kept outdoors.

The graded effect of valence on word recognition in Spanish.

The influence of emotional content on language processing remains unclear. Previous research conducted in English has obtained contradictory results regarding the effects of valence on word recognition. Whereas some studies indicate that valence predicts recognition latencies such that negative words are processed more slowly than positive words, other studies indicate facilitation of responses to emotional (both positive and negative) compared to neutral words.

Observations on the introduction and dissemination of Salmonella in three previously low prevalence status pig farms in the United Kingdom.

In the United Kingdom a serological Salmonella surveillance scheme was run in pigs up to 2012. Farms that maintained a low seroprevalence (<10%) were recognised as "Platinum" pig farms. The aim of this study was to investigate the occurrence and distribution of Salmonella in three farms (17P, 18P and 46P) that had lost their "Platinum" status.

Reading through the life span: Individual differences in psycholinguistic effects.

The effects of psycholinguistic variables are critical to the evaluation of theories about the cognitive reading system. However, reading research has tended to focus on the impact of key variables on average performance. We report the first investigation examining variation in psycholinguistic effects across the life span, from childhood into old age.

In vitro investigations into the use of antimicrobials in combination to maintain efficacy of fluoroquinolones in poultry.

The aim of this study was to determine if apramycin, colistin or lincomycin-spectinomycin, in combination with enrofloxacin, was able prevent the emergence of mutants with reduced susceptibility to fluoroquinolone antibiotics in vitro. MICs were determined for enrofloxacin alone and in combination for panels of Campylobacter (n=37), Escherichia coli (n=52) and Salmonella (n=52) isolates. MIC results suggested that apramycin, colistin and lincomycin-spectinomycin worked in an additive/indifferent way when each was combined with enrofloxacin.

Observations on Salmonella contamination of commercial duck farms before and after cleaning and disinfection.

In the European Union, statutory control of Salmonella is in place in the chicken and turkey sectors, but not in the duck sector. In this study, 14 Salmonella-positive duck farms were sampled before and after cleaning and disinfection, and once the houses had been restocked with a new flock. The cleaning and disinfection programmes used were subdivided into two main categories: ones in which a final formaldehyde disinfection step was included (1) and ones in which it was not included (2).

Virulence Characterisation of Salmonella enterica Isolates of Differing Antimicrobial Resistance Recovered from UK Livestock and Imported Meat Samples.

Salmonella enterica is a foodborne zoonotic pathogen of significant public health concern. We have characterized the virulence and antimicrobial resistance gene content of 95 Salmonella isolates from 11 serovars by DNA microarray recovered from UK livestock or imported meat. Genes encoding resistance to sulphonamides (sul1, sul2), tetracycline [tet(A), tet(B)], streptomycin (strA, strB), aminoglycoside (aadA1, aadA2), beta-lactam (bla TEM), and trimethoprim (dfrA17) were common.

Assessment of anti-Salmonella activity of boot dip samples.

The introduction of pathogens from the external environment into poultry houses via the boots of farm workers and visitors presents a significant risk. The use of boot dips containing disinfectant to help prevent this from happening is common practice, but the effectiveness of these boot dips as a preventive measure can vary. The aim of this study was to assess the anti-Salmonella activity of boot dips that are being used on poultry farms.

Characterization of the invasiveness of monophasic and aphasic Salmonella Typhimurium strains in 1-day-old and point-of-lay chickens.

Egg-related outbreaks of salmonellosis are a significant health concern. Although Salmonella Enteritidis (SE) is the major egg-associated serotype, Salmonella Typhimurium (ST) can also infect the hen's reproductive tract and contaminate eggs. Recently, monophasic and aphasic variants of ST have been reported with increased frequency in Europe, and the isolation of these variants from laying flocks triggers the same legislative restrictions associated with biphasic ST strains.

Reading in Spanish and Italian: effects of age of acquisition in transparent orthographies?

Despite the similar transparency of their orthographies, reading in Italian has been found to be affected by frequency but not age of acquisition (AoA) [Barca, L., Burani, C., & Arduino, L.
