Detection of Vaccine Strain RB51 in Water Buffalo () Milk.

The isolation of RB51 vaccine strain from a milk sample in a water buffalo farm in southern Italy emphasizes the risk to public health of consuming contaminated milk or milk products following illegal vaccination.

The Current Landscape of Antibiotic Resistance of Infantis in Italy: The Expansion of Extended-Spectrum Beta-Lactamase Producers on a Local Scale.

serovar Infantis is one of the five main causes of human salmonellosis in the European Union (EU) and in recent years, has been increasingly reported to carry multiple antimicrobial resistance determinants, including extended-spectrum beta-lactamase (ESBL) genes. In our study, we used WGS-based tools to characterize Infantis strains circulating in the Abruzzo and Molise regions of Italy between 2017 and 2020 and compared this local dataset to the Infantis population present in Italy over the last two decades. Phylogenetic analyses demonstrated that the majority of strains isolated from poultry and turkeys from Abruzzo and Molise were closely related and belonged to one of the two main genetic clusters present in Italy, which were grouped predominantly as ESBL-producing strains that harbored pESI-like plasmid.

Whole Genome Sequencing for Tracing Geographical Origin of Imported Cases of Human Brucellosis in Sweden.

Human infections with s are occasionally reported in Sweden, despite the fact that the national flocks of sheep and goats are officially free from brucellosis. The aim of our study was to analyze 103 isolates of collected from patients in Sweden between 1994 and 2016 and determine their putative geographic origin using whole genome sequencing (WGS)-based tools. The majority of the strains were assigned to East Mediterranean and African lineages.

Origins and global context of Brucella abortus in Italy.

Background: Brucellosis is a common and chronic disease of cattle and other bovids that often causes reproductive disorders. Natural infection in cattle is caused by Brucella abortus and transmission typically occurs during abortions, calving, or nursing. Brucellosis is also a major zoonotic disease due to contamination of dairy products or contact with the tissues of infected animals.

Molecular detection of Nigerian field isolates of subsp. as causative agents of contagious bovine pleuropneumonia.

Contagious bovine pleuropneumonia (CBPP) is a highly contagious respiratory disease affecting cattle and is widely distributed in the sub-Saharan Africa. The objective of this study was to detect subspecies () the causative agent of CBPP from 90 cattle at slaughter using polymerase chain reaction-Restriction fragment length polymorphism. In this study, 450 samples suggestive of CBPP in Maiduguri, Yola and Gombe township abattoirs were processed according to standard protocols.
