Article Synopsis
  • Scientists created a special cell model called the MAGIC model to understand how bacteria live in the human mammary gland, which is important for health.
  • They used a type of cell called MCF10A that can grow similar to cells found in the mammary gland and tested how well bacteria from human milk can stick to this model.
  • The MAGIC model showed important details about how bacteria attach and react to different milk samples, which can help researchers learn more about bacterial interactions in the mammary gland.

Laboratory for Bacterial Zoonosis and Molecular Diagnostics of Bacterial Diseases, Department of Bacteriology and Parasitology, Croatian Veterinary Institute, Zagreb, Croatia.

Introduction: Shortly before the mass mortality event of the noble pen shell () population in the south-eastern Adriatic coast, two rapidly growing strains CVI_P3 (DSM 114013 T, ATCC TSD-295 T) and CVI_P4 were obtained from the organs of individual mollusks during the regular health status monitoring.

Methods: The strains were identified as members of the genus using basic phenotypic characteristics, genus-specific PCR assays targeting the and 16S rRNA genes and the commercial hybridization kit GenoType Mycobacterium CM (Hain Lifescience, Germany). MALDI-TOF mass spectrometry did not provide reliable identification using the Bruker Biotyper Database.

The role of bats in the global microbial ecology no doubt is significant due to their unique immune responses, ability to fly, and long lifespan, all contributing to pathogen spread. Some of these animals hibernate during winter, which results in the altering of their physiology. However, gut microbiota shifts during hibernation is little studied.

Department of Food Hygiene and Technology, Faculty of Veterinary Medicine, University of Belgrade, Bulevar Oslobođenja 18, 11000 Belgrade, Serbia.

The potential risk to human and animal health provides a rationale for research on methicillin-resistant staphylococci (MRS) and mammaliicocci (MRM) in dairy herds. Here, we aimed to estimate their occurrence in the bulk tank milk (BTM) samples collected in 2019-2021 from 283 bovine dairy farms in the Belgrade district. We used whole-genome sequencing to characterize the obtained isolates and assess their genetic relatedness.

University of Ljubljana, Veterinary Faculty, Institute of Microbiology and Parasitology, Ljubljana, Slovenia.

During the 2021 European Food Safety Authority coordinated harmonized monitoring of antimicrobial resistance in species in Slovenia, five -like strains were cultured from caeca of a total of 104 domestic pigs that could not be identified using the standard-prescribed biochemical tests or MALDI-TOF MS. The isolates were obtained using the standard ISO 10272 procedure for the isolation of thermotolerant with prolonged cultivation time. Small -like colonies were observed on mCCDA and CASA agar plates after 2-4 days of incubation; dark-field microscopy revealed relatively big spirilli-shaped bacteria exhibiting characteristic -like motility.

MurC, D, E, and F are ATP-dependent ligases involved in the stepwise assembly of the tetrapeptide stem of forming peptidoglycan. As highly conserved targets found exclusively in bacterial cells, they are of significant interest for antibacterial drug discovery. In this study, we employed a computer-aided molecular design approach to identify potential inhibitors of MurF.

We report the pathological and molecular findings in an adult male Himalayan red panda (Ailurus fulgens fulgens) whose death was attributed to parenchymal brain haemorrhage (PBH) of the thalamus. Post-mortem examination revealed severe, acute PBH and intraventricular haemorrhage with major involvement of the thalamus, as well as scattered chronic microinfarctions. Vascular disease in the brain and other organs was suggestive of systemic hypertension.

Lyssaviruses are the causative agents of rabies, a zoonotic, fatal disease that is thought to be ancestral to bats. In the last decade, the detection of bat associated lyssaviruses is increasing also in Europe. Within a retrospective bat associated lyssavirus surveillance study a total of 225 dead bats of 21 bat species were collected in Slovenia between 2012 and 2019 and tested by specific real-time RT-PCR method.

Novel bacterial topoisomerase inhibitors (NBTIs) are a new class of antibacterial agents that target bacterial type II topoisomerases (DNA gyrase and topoisomerase IV). Our recently disclosed crystal structure of an NBTI ligand in complex with DNA gyrase and DNA revealed that the halogen atom in the para position of the phenyl right hand side (RHS) moiety is able to establish strong symmetrical bifurcated halogen bonds with the enzyme; these are responsible for the excellent enzyme inhibitory potency and antibacterial activity of these NBTIs. To further assess the possibility of any alternative interactions (e.

In Russia, antiretroviral therapy (ART) coverage has significantly increased, which, in the absence of routine genotyping testing, could lead to an increase in HIV drug resistance (DR). The aim of this study was to investigate the patterns and temporal trends in HIV DR as well as the prevalence of genetic variants in treatment-naïve patients from 2006 to 2022, using data from the Russian database (4481 protease and reverse transcriptase and 844 integrase gene sequences). HIV genetic variants, and DR and DR mutations (DRMs) were determined using the Stanford Database.

Amide containing NBTI antibacterials with reduced hERG inhibition, retained antimicrobial activity against gram-positive bacteria and in vivo efficacy.

Eur J Med Chem

March 2023

Department of Pharmaceutical Chemistry, Faculty of Pharmacy, University of Ljubljana, Aškerčeva Cesta 7, 1000, Ljubljana, Slovenia. Electronic address:

Novel bacterial topoisomerase inhibitors (NBTIs) are new promising antimicrobials for the treatment of multidrug-resistant bacterial infections. In recent years, many new NBTIs have been discovered, however most of them struggle with the same issue - the balance between antibacterial activity and hERG-related toxicity. We started a new campaign by optimizing the previous series of NBTIs, followed by the design and synthesis of a new, amide-containing focused NBTI library to reduce hERG inhibition and maintain antibacterial activity against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA).

First Detection of Honeybee Pathogenic Viruses in Butterflies.

Insects

October 2022

Institute of Microbiology and Parasitology, Veterinary Faculty, University of Ljubljana, Gerbičeva 60, 1000 Ljubljana, Slovenia.

Article Synopsis
  • Several pathogens, including honeybee viruses, may be contributing to the decline of pollinators, leading researchers to investigate potential virus transmission to butterflies.
  • A study conducted in Slovenia involved sampling 120 butterflies and Carniolan honeybees, resulting in the detection of several honeybee viruses in both groups, particularly ABPV, BQCV, LSV3, and SBV.
  • The findings suggest that butterflies may act as passive carriers of these viruses, with a higher detection rate in areas with more honeybee populations, indicating a link between infected bees and the presence of viruses in butterflies.

Aim: Our aim was to give a comparative assessment of the effectiveness of using narlaprevir in combination with pegylated interferon-alpha-2a (Peg-IFN-alpha-2a) and interferon-free mode in patients with chronic hepatitis C (CHC).

Materials And Methods: The prospective cohort study included 187 patients infected with genotype 1b of hepatitis C virus. Of these, 107 (the 1st group of patients) received narlaprevir 200 mg once a day, ritonavir 100 mg once a day, Peg-IFN-alpha-2a 180 mkg subcutaneously once a week and ribavirin at a dose depending on body weight (10001200 mg per day) for 12 weeks, and then the standart "dual" therapy (Peg-IFN-alpha-2a + ribavirin) was continued until 24 weeks.
