Positive associations matter: Microbial relationships drive tick microbiome composition

Molecular Ecology, Volume 32, Issue 14, Page 4078-4092, July 2023., 2023
Abstract Untangling how factors such as environment, host, associations among bacterial species and dispersal predict microbial composition is a fundamental challenge. In this study, we use complementary machine‐learning approaches to quantify the relative role of these factors in shaping microbiome variation of the blacklegged tick Ixodes scapularis ...

Transcriptional and functional characterizations of multiple flagellin genes in spirochetes

Molecular Microbiology, Volume 118, Issue 3, Page 175-190, September 2022., 2022
The oral spirochete Treponema denticola has periplasmic flagella (PFs) that are mainly composed of three flagellin proteins (FlaB1, FlaB2 and FlaB3) and a sheath protein FlaA. Each protein contributes to the motility but none of them is absolutely required.

Streptococcus equi subsp. zooepidemicus infection of pigs leads to shedding in faeces and a carrier state

Transboundary and Emerging Diseases, Volume 69, Issue 5, Page e1503-e1509, September 2022., 2022
Abstract In 2019, Streptococcus equi subsp. zooepidemicus was recognized as an emerging pathogen of swine, associated with sudden deaths, increased abortion rates and septicaemia. Limited data are available regarding this disease in pigs. The objectives of this study were to clarify clinical progression, pathogen shedding, transmission, gross and ...

Welfare of pigs on farm

EFSA Journal, Volume 20, Issue 8, August 2022., 2022
Abstract This scientific opinion focuses on the welfare of pigs on farm, and is based on literature and expert opinion. All pig categories were assessed: gilts and dry sows, farrowing and lactating sows, suckling piglets, weaners, rearing pigs and boars. The most relevant husbandry systems used in Europe are described.

Porcine reproductive and respiratory syndrome virus impacts on gut microbiome in a strain virulence‐dependent fashion

Microbial Biotechnology, Volume 15, Issue 3, Page 1007-1016, March 2022., 2022
PRRSV, a porcine respiratory pathogen, indirectly impacts on gut microbiome composition in a strain virulence dependent fashion in association with selected immune markers. Summary Porcine reproductive and respiratory syndrome (PRRS) is a viral disease defined by reproductive problems, respiratory distress and a negative impact on growth rate and ...

Carriage of Brachyspira hyodysenteriae on common insect vectors

Veterinary Microbiology, 2022
The interactions of likely insect and murine vectors of the causative agent of swine dysentery, Brachyspira hyodysenteriae, were investigated. Insects were collected and analysed from 3 pig farms positive for B hyodysenteriae. Within these farms, several Musca domestica and Orphyra adult fly, Blatta sp.

Maximum levels of cross‐contamination for 24 antimicrobial active substances in non‐target feed.
Part 2: Aminoglycosides/aminocyclitols: apramycin, paromomycin, neomycin and spectinomycin

EFSA Journal, Volume 19, Issue 10, October 2021., 2021
Abstract The specific concentrations of apramycin, paromomycin, neomycin and spectinomycin in non‐target feed for food‐producing animals, below which there would not be an effect on the emergence of, and/or selection for, resistance in bacteria relevant for human and animal health, as well as the specific antimicrobial concentrations in feed which have
