Article Synopsis
  • The domestication process has been extensively studied, beginning with Belyaev's experiment on silver foxes, which showed that selecting for tameness disrupts systems controlling development, leading to typical domestication traits.
  • Additional hypotheses, like the thyroid rhythm and neural crest cell hypotheses, have been proposed, but the recent parasite-mediated domestication hypothesis (PMD) suggests that endoparasites may play a critical role in this process.
  • Research comparing parasite loads in wild boars and domestic pigs from Slovenia and Croatia found different parasite taxa in both populations, providing a basis to explore how parasite susceptibility may have contributed to domestication.

Microbiota composition of an autochthonous Krškopolje pig breed reared in two different organic production systems.

Res Vet Sci

January 2025

University of Ljubljana, Veterinary Faculty, Clinic for Reproduction and Large Animals, Clinic for Ruminants and Pigs, Ljubljana, Slovenia.

It has been shown that different production systems (conventional vs. pasture-raised pigs) and co-rearing of pigs with other livestock influence the gut microbiota composition in pigs. In this study, two independent trials were conducted to investigate the 16S fecal microbiota of the autochthonous Krškopolje pig.

Infantis poses a significant challenge in poultry production due to its persistence and resistance to disinfectants. This study investigated the survival of the Infantis strain on different surfaces and evaluated the efficacy of disinfectants in both preventing and treating biofilms. The survival of the tested Infantis strain was assessed on plastic and stainless steel surfaces after 24 and 48 h.

Background: The novel bacterial topoisomerase inhibitors (NBTIs) developed in our laboratory show potent on-target enzyme inhibition but suffer from low activity against Gram-negative bacteria.

Methods: With the aim of improving the antibacterial activity of our compounds against Gram-negative bacteria, we tested them in combination with different efflux pump inhibitors (EPIs), a strategy that showed promise in several other classes of antimicrobials. We also investigated the combined effect of NBTIs with ATP-competitive inhibitors of bacterial type II topoisomerases (ACIs), as well as the antibiofilm properties of our compounds and the combination with EPIs against early and mature biofilm.

Towards harmonized laboratory methodologies in veterinary clinical bacteriology: outcomes of a European survey.

Front Microbiol

October 2024

Department of Veterinary Anatomy, Physiology and Pathology, Institute of Infection, Veterinary and Ecological Sciences, School of Veterinary Science, Leahurst Campus, University of Liverpool, Neston, United Kingdom.

Introduction: Veterinary clinical microbiology laboratories play a key role in antimicrobial stewardship, surveillance of antimicrobial resistance and prevention of healthcare associated-infections. However, there is a shortage of international harmonized guidelines covering all steps of veterinary bacterial culture from sample receipt to reporting.

Methods: In order to gain insights, the European Network for Optimization of Veterinary Antimicrobial Treatment (ENOVAT) designed an online survey focused on the practices and interpretive criteria used for bacterial culture and identification (C&ID), and antimicrobial susceptibility testing (AST) of animal bacterial pathogens.

The diarrheagenic (DEC) is the major cause of diarrheal diseases in Africa, including Ethiopia. However, the genetic diversity of pathotypes found in Ethiopia has not been studied well. This study aimed to characterize potential DEC belonging to enteropathogenic (EPEC), Shiga toxin-producing (STEC), enteroaggregative (EAEC), enterotoxigenic (ETEC), and enteroinvasive (EIEC) pathotypes from stool specimens of patients attending primary healthcare units ( = 260) in Addis Ababa and Hossana using whole-genome sequencing.

The global spread of antimicrobial resistance genes (ARGs) in is a major public health concern. The aim of this study was to investigate the genomic characteristics of extended-spectrum β-lactamase (ESBL)-producing and third-generation cephalosporin-resistant from a previously obtained collection of 260 isolates from fecal samples of patients attending primary healthcare facilities in Addis Ababa and Hossana, Ethiopia. A total of 29 isolates (19 phenotypically confirmed ESBL-producing and 10 third-generation cephalosporin-resistant isolates) were used.

In the final phases of bacterial cell wall synthesis, penicillin-binding proteins (PBPs) catalyze the cross-linking of peptidoglycan. For many decades, effective and non-toxic β-lactam antibiotics have been successfully used as mimetics of the d-Ala-d-Ala moiety of the natural substrate and employed as irreversible inhibitors of PBPs. In the years following their discovery, the emergence of resistant bacteria led to a decline in their clinical efficacy.

Adult female and male nematodes were found in the oesophagus of a free-living roe deer () in Slovenia during passive health surveillance of wildlife. The genus was determined by light microscopy based on the genus-specific cuticular bosses in the anterior part of the parasite. Molecular methods were used to confirm the species , which has zoonotic potential.

In a previous study characterizing strains deficient in selenium metabolism, 50 strains were found to be similar to, but distinct from, the selenonegative species . Initial characterization based on multilocus sequence typing and the phylogeny of a set of 20 core genes determined that these strains form three putative taxa within the selenonegative cluster. A polyphasic study was undertaken here to further clarify their taxonomic position within the genus.

The role of in canine fertility disorders is still poorly understood. As infection is often asymptomatic, there is an increasing need for appropriate diagnostic methods and treatment plans that would allow the reliable detection of infection and rapid alleviation of infection symptoms in affected dogs. In this study, we included 14 dogs with fertility problems and 16 dogs without fertility disorder signs.

Paratuberculosis (PTB), or Johne's disease, is a disease with worldwide distribution caused by subsp (MAP) that leads to chronic enteritis, primarily in ruminants. Even subclinical infection significantly reduces the animals' performance, and consequences of the disease lead to high economic losses for the cattle industry. To estimate the economic burden of bovine PTB and to evaluate the benefits of a potential control program, accurate estimates of the production effects associated with the disease are required.

The Carniolan honey bee (Apis mellifera carnica) plays an essential role in crop pollination, environment diversity, and the production of honey bee products. However, the health of individual honey bees and their colonies is under pressure due to multiple stressors, including viruses as a significant threat to bees. Monitoring various virus infections could be a crucial selection tool during queen rearing.

Rotavirus infection is a leading cause of severe dehydrating gastroenteritis in children under 5 years of age. Although rotavirus-associated mortality has decreased considerably because of the introduction of the worldwide rotavirus vaccination, the global burden of rotavirus-associated gastroenteritis remains high. Current vaccines have a number of disadvantages; therefore, there is a need for innovative approaches in rotavirus vaccine development.
