Challenges and potential opportunities for improving One Health surveillance in low-resource settings: Insights from rabies surveillance in Malawi

Precious Innocent Mastala, Patrick Ken Kalonde, Enerst Chikhola, Jordana Burdon Bailey et autres

The growing threat of zoonotic diseases has driven an increased interest in “One Health”, a framework that demands a more holistic approach to understanding, preventing and controlling the emergence and spread of health risks at the human-animal-environment interface. This approach requires systems …

Closed Genome Sequences of Providencia alcalifaciens Isolates from Dogs

Thomas H. A. Haverkamp, Håkon Pedersen Kaspersen, Øivind Øines, Bjørn Spilsberg et autres

Eight Providencia alcalifaciens isolates from eight different dogs in Norway with acute hemorrhagic diarrhea were sequenced. Based on Illumina and Oxford Nanopore Technologies sequencing, all of the genomes were complete and closed after hybrid assembly.

Streptococcus dysgalactiae ssp. dysgalactiae in Norwegian bovine dairy herds: Risk factors, sources, and genomic diversity

Marit Smistad, Håkon Pedersen Kaspersen, Fiona Valerie Franklin‐Alming, Cecilia Wolff et autres

Despite the importance of Streptococcus dysgalactiae ssp. dysgalactiae (SDSD) as an udder pathogen, the reservoir and epidemiological characteristics of this bacterium are largely unexplored. The aims of this study were to investigate risk factors for SDSD intramammary infections (SDSD-IMI) in Norwegian bovine …

Emergence of methicillin resistance predates the clinical use of antibiotics

Jesper Larsen, Claire L. Raisen, Xiaoliang Ba, Nicholas John Sadgrove et autres

Abstract The discovery of antibiotics more than 80 years ago has led to considerable improvements in human and animal health. Although antibiotic resistance in environmental bacteria is ancient, resistance in human pathogens is thought to be a modern phenomenon that is driven …

An Official Outbreak Investigation of Acute Haemorrhagic Diarrhoea in Dogs in Norway Points to Providencia alcalifaciens as a Likely Cause

Hannah Joan Jørgensen, Mette Valheim, Camilla Sekse, Bjarne Bergsjø et autres

An outbreak investigation was initiated in September 2019, following a notification to the Norwegian Food Safety Authority (NFSA) of an unusually high number of dogs with acute haemorrhagic diarrhoea (AHD) in Oslo. Diagnostic testing by reporting veterinarians had not detected a cause. …

Molecular detection and genotype characterization of Streptococcus dysgalactiae from sheep flocks with outbreaks of infectious arthritis

Marit Smistad, Tore Tollersrud, Lars Austbø, Davide Porcellato et autres

Outbreaks of infectious arthritis in young lambs are a growing concern for the Norwegian sheep industry. In other countries, Streptococcus dysgalactiae subspecies dysgalactiae (SDSD) is a frequent cause of such outbreaks. The objectives of this study were to investigate the causes of …

Whole genome sequencing reveals possible host species adaptation of Streptococcus dysgalactiae

Davide Porcellato, Marit Smistad, Siv Borghild Skeie, Hannah Joan Jørgensen et autres

Streptococcus dysgalactiae (SD) is an emerging pathogen in human and veterinary medicine, and is associated with several host species, disease phenotypes and virulence mechanisms. SD has traditionally been divided into the subspecies dysgalactiae (SDSD) and subsp. equisimilis (SDSE), but recent molecular studies …

Longitudinal Study of the Bulk Tank Milk Microbiota Reveals Major Temporal Shifts in Composition

Davide Porcellato, Marit Smistad, Alberto Bombelli, Ahmed Abdelghani et autres

Introduction of microbial contaminations in the dairy value chain starts at the farm level and the initial microbial composition may severely affect the production of high-quality dairy products. Therefore, understanding the farm-to-farm variation and longitudinal shifts in the composition of the bulk …
