Antimicrobial resistance (AMR) data generated by diagnostic animal health laboratories are underutilized for AMR reporting in Canada. Data assessment, review of practices in other jurisdictions, and expert interviews were used to develop an evidence-guided plan to generate AMR reports from British Columbia Animal Health Centre (AHC) data that would provide transparent, timely, and useful information to public health practitioners, the food animal sector, and the general public. Using the Canadian Animal Health Surveillance Network (CAHSN) platform was the most efficient method of data retrieval...

Infective endocarditis (IE) secondary to Staphylococcus lugdunensis has been increasingly recognized since 1988. IE-related thromboembolism represents an associated complication of the disease and carries a dismal prognosis. However, the incidence of cerebrovascular accident secondary to S. lugdunensis IE is relatively uncommon and its treatment has not been clearly elucidated yet. We performed an extensive literature search using Pubmed, Medline, Scopus, and Google Scholar to identify the articles using the following keywords: 'Staphylococcus lugdunensis', 'infective endocarditis', 'stroke', and 'cerebrovascular accident...

Routine diagnostic laboratory results, e.g. numbers of meticillin-resistant Staphylococcus aureus (MRSA) bacteraemias, have been used as health-care-associated infection quality indicators for decades. The English health-care-associated infection quality indicator system was one of the earliest in the world to mandate the collection and public reporting of such data and has been associated with a reduction of MRSA bacteraemias and Clostridium difficile infections but has shown mixed results for other infections...

Raw milk may be a risk for public health if it is contaminated with zoonotic pathogens. To study the prevalence in unpasteurized milk from Swedish farms, bovine and small ruminant dairy farms were sampled. Since the sampling method and transport conditions may influence the outcome of analyses, efforts were made to optimize the methodology. Culturing of bacteria was done from in-line milk filters collected from the milk pipe at the point where it enters the milk bulk tank at the farms and this way of sampling was compared to sampling bulk tank milk (BTM) directly...

In the United States, age-adjusted opioid overdose death rates increased by >200% during 1999-2015, and heroin overdose death rates increased nearly 300% during 2011-2015 (1). During 2011-2013, the rate of heroin use within the past year among U.S. residents aged ≥12 years increased 62.5% overall and 114.3% among non-Hispanic whites, compared with 2002-2004 (2). Increases in human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections related to increases in injection drug use have been recently highlighted (3,4); likewise, invasive bacterial infections, including endocarditis, osteomyelitis, and skin and soft tissue infections, have increased in areas where the opioid epidemic is expanding (5-7)...

Antibiotic-resistant infections that do not respond to available drugs are becoming more common. Methicillin-resistant Staphylococcus aureus, carbapenem-resistant enterobacteria ("superbugs"), and many others pose a continuous threat to public health. To provide tools to combat such deadly infections, we present in this study a homogeneous assay focused on an insufficiently addressed molecular interaction linked to ribosomal translation. We show that a fluorescence resonance energy transfer (FRET) based screening assay can identify antibiotic molecules that inhibit ternary complex (EF-Tu:tRNA:GTP complex) formation, and therefore, protein synthesis in bacteria...

Staphylococcus aureus causes a wide range of diseases that together embody a significant public health burden. Aided by metabolic flexibility and a large virulence repertoire, S. aureus has the remarkable ability to hematogenously disseminate and infect various tissues, including skin, lung, heart, and bone, among others. The hallmark lesions of invasive staphylococcal infections, abscesses, simultaneously denote the powerful innate immune responses to tissue invasion as well as the ability of staphylococci to persist within these lesions...

During colonization of biomaterials and host tissues, surface-attached bacteria are subjected to mechanical stresses, including hydrodynamic flow and cell-surface contacts. Two publications show that mechanical force activates the adhesive function of Staphylococcus aureus surface proteins, thereby providing the pathogen with a means to withstand high shear stress during colonization.

Given the increased interest in public hygiene due to outbreaks of food poisoning, increased emphasis has been placed on developing novel monitoring systems for point-of-care testing (POCT) to evaluate pathogens causing foodborne illnesses. Here, we demonstrate a pathogen evaluation system utilizing simple film-based microfluidics, featuring simultaneous gene amplification, solution mixing, and electrochemical detection. To minimize and integrate the various functionalities into a single chip, patterned polyimide and polyester films were mainly used on a polycarbonate housing chip, allowing simple fabrication and alignment, in contrast to conventional polymerase chain reaction, which requires a complex biosensing system at a bench-top scale...

Bacterial infection has always been a great threat to public health, and new antimicrobials to combat it are urgently needed. Here, a series of quaternized β-chitin derivatives is prepared simply and homogeneously in an aqueous KOH/urea solution, which is a high-efficiency, energy-saving, and "green" route for the modification of chitin. The mild reaction conditions keep the acetamido groups of β-chitin intact and introduce quaternary ammonium groups on the primary hydroxyl at the C-6 position of the chitin backbone, allowing the quaternized β-chitin derivatives (QCs) to easily form micelles...

Antibiotic resistance is a serious threat to global public health, and methicillin-resistant Staphylococcus aureus (MRSA) is a poignant example. The macrolactone natural product albocycline, derived from various Streptomyces strains, was recently identified as a promising antibiotic candidate for the treatment of both MRSA and vancomycin-resistant S. aureus (VRSA), which is another clinically relevant and antibiotic resistant strain. Moreover, it was hypothesized that albocycline's antimicrobial activity was derived from the inhibition of peptidoglycan (i...

Hospital infections is a public health problem that can occur with the use of catheters and endotracheal tubes (ETT). Pathogenic microorganisms may adhere to surfaces of these materials forming biofilm. Microbial biofilms presents an extracellular polymer matrix that promotes resistance of microorganisms to factors such as pH, temperature and drugs. The ETT is used to assist a patient with compromised breathing function. ETT biofilm may cause ventilator-associated pneumonia. Pseudomonas aeruginosa and Staphylococcus aureus pneumonia is associated with a 21-fold increase in risk for mechanical ventilation...
