Antimicrobial susceptibility of western Canadian Brachyspira isolates: Development and standardization of an agar dilution susceptibility test method.

The re-emergence of Brachyspira-associated disease in pigs since the late 2000s has illuminated some of the diagnostic challenges associated with this genus; notably, the lack of standardized antimicrobial susceptibility testing (AST) methods and interpretive criteria. Consequently, laboratories have relied heavily on highly variable in-house developed methods. There are currently no published investigations describing the antimicrobial susceptibility of Brachyspira isolates collected from pigs in Canada.

isolated from diseased pigs are phylogenetically related but harbour different number of toxin gene copies in their genomes.

Objective: The Gram-negative bacterium is an agent of global importance to the swine industry and the cause of lethal respiratory or septicaemic disease in pigs of different ages. Between 2018 and 2019, seven commercial farms in western Canada experienced episodes of increased mortality due to infection in grower pigs. The goal of this work was to profile, with molecular methods, isolated from diseased pigs and to compare them to other isolates.

A Study on Victims of Intimate Partner Violence Reported to Colombo North Teaching Hospital, Sri Lanka During 2019-2021.

Introduction: Intimate partner violence (IPV) is a common issue in any society and the reported cases are just the tip of an iceberg as most of the victims are reluctant to come to the criminal justice system. Forensic experts are often encountering the victims who chose to seek justice. Evaluation of the nature, consequences, and underlying factors are needed in planning preventive measures.

Medicolegal Aspects of Victims of Assault Admitted to a Tertiary Care Hospital in Sri Lanka.

Introduction: Violence with physical assault is a common cause of morbidity and mortality prevalent but not limited to underdeveloped countries. The opinion of the forensic expert is often indispensable in such cases to determine the penalties. This study was planned to describe the pattern of presentation of the victims and evaluate the strengths and limitations in formulating a scientific medicolegal opinion based on the findings of the victim.

Validation of an antimicrobial susceptibility testing protocol for Brachyspira hyodysenteriae and Brachyspira pilosicoli in an international ring trial.

Brachyspira hyodysenteriae and Brachyspira pilosicoli cause economically important enteric disease in pigs. Treatment of these infections often includes antimicrobial administration, which can be most effective when therapeutic options are informed by antimicrobial susceptibility testing data. Here we describe a method for broth dilution antimicrobial susceptibility testing of these bacteria, both of which are difficult to culture in vitro.
