Comparative SARS-CoV-2 Omicron BA.5 variant and D614G-Wuhan strain infections in ferrets: insights into attenuation and disease progression during subclinical to mild COVID-19
Frontiers in veterinary science publica este artículo de investigación
Introduction: As the SARS-CoV-2 virus continues to evolve and new variants emerge, it becomes crucial to understand the comparative pathological and immunological responses elicited by different strains. This study focuses on the original Wuhan strain and the Omicron variant, which have demonstrated significant differences in clinical outcomes and immune responses.
Methods: We employed ferrets as an experimental model to assess the D614G variant (a derivative of the Wuhan strain) and the Omicron BA.5 variant. Each variant was inoculated into separate groups of ferrets to compare disease sever…

The Importance of Genomic Context in Interpreting Fosfomycin Resistance in Klebsiella pneumoniae
International Journal of Antimicrobial Agents publica este artículo de investigación
Dear Editor,
In recent years, we have witnessed advancements in sequencing technologies that allow rapid sequencing of numerous bacterial samples, creating an extensive database of genomes. This information is used nowadays to understand the epidemiological status and trends of resistance, contributing to the change of therapeutic guidelines in the use of antimicrobial agents. For example, the emergence of fosfomycin resistance is of major clinical interest, as this antibiotic is increasingly used, particularly in the treatment of urinary tract infections and sepsis caused by multidrug-resist…

Time, temperature and media: the three keys to improve the recovery of Campylobacter fetus subsp. venerealis from preputial bull samples
Veterinary Research Communications publica este artículo de investigación
The isolation of Campylobacter fetus subsp. venerealis (Cfv) from clinical samples is the gold standard for confirming cases of bovine genital campylobacteriosis, an important cause of infertility in cattle and a potential public health concern. Furthermore, isolation is also necessary for the development of autologous vaccines, characterization of strains for antimicrobial susceptibility patterns, etc. Nevertheless, the sensitivity of culture methods is usually low, and there is no standardized protocol to maximize the recovery of Cfv from clinical samples. The aim of the current study is to …
