BACKGROUND: Most of surgical site infections (SSI) are caused by commensal and pathogenic agents from the patient's microbiota, which may include antibiotic resistant strains. Pre-surgical asepsis of the skin is one of the preventive measures performed to reduce SSI incidence and also antibiotic resistance dissemination. However, in veterinary medicine there is no agreement on which biocide is the most effective. The aim of this study was to evaluate the effectiveness of two pre-surgical skin asepsis protocols in dogs...

Developing CRISPR/Cas9-mediated non-transgenic mutants in asexually propagated perennial crop plants is challenging but highly desirable. Here, we report a highly useful method using an Agrobacterium -mediated transient CRISPR/Cas9 gene expression system to create non-transgenic mutant plants without the need for sexual segregation. We have also developed a rapid, cost-effective, and high-throughput mutant screening protocol based on Illumina sequencing followed by high-resolution melting (HRM) analysis. Using tetraploid tobacco as a model species and the phytoene desaturase ( PDS ) gene as a target, we successfully created and expediently identified mutant plants, which were verified as tetra-allelic mutants...

Sepsis is a medical emergency, which requires the initiation of broad-spectrum antimicrobial agents as early as possible. In the absence of positive microbiological cultures providing targeted antimicrobial advice, broad-spectrum antibiotics are commonly continued until there is clinical evidence of infection resolution. With an absence of robust evidence to inform when it is safe to stop antimicrobial agents in sepsis, the duration of antimicrobial courses may be longer than is required. Prolonged courses of potent broad-spectrum antimicrobials increase the risk of adverse drug events and contribute to the growing emergence of multidrug resistant pathogens, which is a global public health emergency...

AIMS: Pseudomonas aeruginosa is a well-known pathogen responsible for various infections due to its capability to develop biofilm and various virulent phenotypes that are regulated by quorum sensing. Pathogenesis of the bacteria may be halted by interfering with the signaling molecules and the quorum sensing receptors. Therefore, the present study explores the potential of parthenolide, a sesquiterpene lactone of feverfew plant, as a promising candidate against P. aeruginosa PAO1 associated virulence factors and biofilm...

In the past few years, the World Health Organization has been warning that the post-antibiotic era is an increasingly real threat. The rising and disseminated resistance to antibiotics made mandatory the search for new drugs and/or alternative therapies that are able to eliminate resistant microorganisms and impair the development of new forms of resistance. In this context, antimicrobial photodynamic therapy (aPDT) and helical cationic antimicrobial peptides (AMP) are highlighted for the treatment of localized infections...

Diatoms constitute the most diverse group of microalgae and have long been recognised for their large biotechnological potential. In the wake of growing research interest in new model species and development of commercial applications, there is a pressing need for long-term preservation of diatom strains. While cryopreservation using dimethylsulfoxide (DMSO) as a cryoprotective agent is the preferred method for long-term strain preservation, many diatom species cannot be successfully cryopreserved using DMSO...

Acute management of open fractures is associated with high morbidity and mortality. Recommended antibiotic regimens for all Gustilo-Anderson fracture grades include first-, second-, and third-generation cephalosporins. Expanded gram-negative coverage is recommended for Grade II and III fractures if a first- or second-generation cephalosporin is selected, and additional anaerobic coverage is required if the open fracture is contaminated with organic or farm-related material. Open fractures endure a high rate of bacterial contamination, and antibiotics have demonstrated effectiveness at reducing infection rates when initiated early...

INTRODUCTION: Anaerobic bacteria are believed to be common pathogens in severe infections. Yet, they are difficult to culture and consequently often unrecognised in clinical infections. Metronidazole is often used empirically for potential anaerobic infections, as the resistance to metronidazole is low. However, disadvantages of metronidazole use exist, including drug interactions, side effects and economical expenses. Currently, the balance between the benefits and harms of empirical metronidazole for severe bacterial infections is unknown...

We developed a protocol for isolating the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) from anurans. We sampled skin tissues from 2 common treefrogs, Pseudacris regilla and P. triseriata, collected from populations with high infection prevalence. We sampled tissues from 3 anatomical ventral regions (thigh, abdomen, and foot) where the pathogen is thought to concentrate. To mitigate potential bacterial contamination, we used a unique combination of 4 antibiotics. We quantified infections on frogs as zoospore equivalents (ZE) using a swabbing approach combined with quantitative real-time polymerase chain reaction...

BACKGROUND: Bacterial contamination of cord blood (CB) represents a safety risk for transplantation patients. CB sterility testing at Canadian Blood Services' Cord Blood Bank is performed using a 1:1 mix of CB-derived plasma and red blood cells (RBCs). Culture bottles of an automated culture system, which lack antimicrobial neutralization properties, are used for bacterial screening of CB. This process is unsuitable for CB-containing antibiotics, potentially resulting in false-negative results...

BACKGROUND: Acute calculous cholecystitis (ACC) is the most common complication of cholelithiasis. Laparoscopic cholecystectomy (LC) is the gold standard treatment in mild and moderate forms. Currently there is consensus for the use of antibiotics in the preoperative phase of ACC. However, the need for antibiotic therapy after surgery remains undefined with a low level of scientific evidence. METHODS: The CHART (Cholecystectomy Antibiotic Randomised Trial) study is a single-center, prospective, double blind, and randomized trial...
