Houtt. is the source of various phenolic compounds: phenolic acids, flawan-3-ols, and stilbenes, with a broad range of biological activity. The rhizome (underground organ of these plants) is abundant in secondary metabolites but, in natural conditions, may accumulate various toxic substances (such as heavy metals) from the soil.

Introduction: This article presents the fourth detection of macroscopic cystic lesions due to sarcocystosis in domestic pigs during routine meat inspection worldwide, and the first molecular detection of in a domestic pig in Poland. Pigs can become intermediate hosts for by accidental ingestion of oocysts or sporocysts present in food or water contaminated by the faeces of canids (definitive hosts).

Material And Methods: The affected swine showed no clinical symptoms such as weight loss, dermatitis or dyspnoea suggesting sarcocystosis.

Substances of organic origin are seeing increasing use in agriculture as rich sources of nutrients for plants. The aim of this study was to determine the microbiological contamination of sewage sludge and digestate to assess their safe use as fertilizers in Poland. The assessment of microbial soil, sewage sludge and digestate contamination was based on the total number of mesophilic bacteria and Gram-negative bacteria from the family.

Article Synopsis
  • Eucoleus aerophilus is a parasite affecting carnivores and occasionally humans, found in 38 countries worldwide.
  • A study in Central Europe examined 342 red fox fecal samples for the prevalence of this parasite using PCR methods and found E. aerophilus DNA in 230 samples.
  • The research identified 22 genetic variations of E. aerophilus and highlighted the high prevalence of Capillariidae eggs, along with other parasite eggs in the samples, marking it as the first molecular analysis of E. aerophilus in Poland.

Quantitative Systems Pharmacology (QSP) models are increasingly being applied for target discovery and dose selection in immuno-oncology (IO). Typical application involves virtual trial, a simulation of a virtual population of hundreds of model instances with model inputs reflecting individual variability. While the structure of the model and initial parameterisation are based on literature describing the underlying biology, calibration of the virtual population by existing clinical data is frequently required to create tumour and patient population specific model instances.

Introduction And Objective: The hygienic status of arable soils in most developed countries has been unknown. In the presented study, a preliminary investigation was undertaken to determine the contamination with eggs of parasitic nematodes in the soil of arable fields in Poland. The aim of the study was to determine whether such contamination is common enough to constitute a significant problem and what factors may influence it.

Introduction And Objective: Official food control laboratories ensure food safety using reliable, validated methods. Council Regulations (EC) No. 853/2004, 854/2004 and 882/2004 of the European Parliament established hygiene rules the production of food of animal origin, together with requirements for official controls.

Introduction: The aim of the study was to determine the genetic diversity of in pigs in highly endemic areas in Poland, as well as to attempt to confirm the occurrence and geographical distribution of haplotypes characteristic for these areas, which were previously described on the basis of examination of adult tapeworms isolated from foxes.

Material And Methods: Twenty samples of larval forms were obtained from pigs' livers in four provinces of Poland. Genetic analyses were conducted on sequences of two mitochondrial genes: and .

Article Synopsis
  • Natural fertilizers and organic wastes can contaminate agricultural soil with parasites, posing health risks to humans and animals, necessitating effective control measures.
  • The study examined various methods for detecting Ascaris suum eggs in different soil types, using a total of six testing methods, including standard Polish methods.
  • The PN-19006 method was found to be the most effective for detecting A. suum eggs, making it a potential standard for testing soil for parasite contamination.

Introduction And Objective: Lyme borreliosis (LB) is the most frequent tick-borne disease with 17,338 cases reported in Poland in 2022. Since research on a LB vaccine is still ongoing, the promotion of individual behaviours and limiting of tick exposure is one of the most effective ways to prevent LB. The aim of the study was to evaluate the effectiveness of the LB prevention programme by assessing the knowledge, practice behaviours, seroprevalence of LB and satisfaction among the population of the Lublin Province in eastern Poland.

Cellular heterogeneity is a phenomenon in which cell populations are composed of subpopulations that vary in their behavior. Heterogeneity is particularly pronounced in cancer cells and can affect the efficacy of oncological therapies. Previous studies have considered heterogeneity dynamics to be indicative of evolutionary changes within subpopulations; however, these studies do not consider the short-time morphological plasticity of cells.

The alimentary route is the second most important route of tick-borne encephalitis infection. In Poland, the last TBE case due to the consumption of unpasteurized milk or dairy products of infected animals was recorded in 2017 as the fourth documented outbreak of TBEV infection in the country. In this study, two patients infected with TBEV through consumption of unpasteurized goat's milk from one source are described from a cluster of eight cases.

Article Synopsis
  • * In Europe, the disease is primarily linked to consuming meat from wild boars, pigs, and horses, with illegal hunting of wild boars being a major risk factor for human cases.
  • * The article suggests a new approach for epidemiological investigations on pig farms to better trace the source of infection and prevent further spread, improving upon current methods that are inadequate.

Antimicrobial peptides emerge as compounds that can alleviate the global health hazard of antimicrobial resistance, prompting a need for novel computational approaches to peptide generation. Here, we propose HydrAMP, a conditional variational autoencoder that learns lower-dimensional, continuous representation of peptides and captures their antimicrobial properties. The model disentangles the learnt representation of a peptide from its antimicrobial conditions and leverages parameter-controlled creativity.

encodes seipin, a transmembrane endoplasmic reticulum protein associated with lipodystrophy and severe metabolic complications, including diabetes and hepatic steatosis. In pigs, expression increases during adipocyte differentiation. In the present study, we identified significant gene variants associated with fat deposition (FD)-related processes based on subcutaneous fat tissue RNA-seq data.

Article Synopsis
  • A study investigates a zoonotic parasite affecting both human and animal health, identifying infected meat as a significant source of human infections particularly in Europe.
  • The research utilized a systematic review of 226 publications and applied a Bayesian hierarchical model to estimate regional seroprevalence in various animal species, showing significant variation based on species, regions, and rearing conditions.
  • Findings revealed that seroprevalence was highest in Eastern Europe and lowest in Northern Europe, with outdoor-kept sheep showing the highest infection rate, emphasizing the need for better data and source attribution to address human infection risks.

Background: The flagellated parasite Giardia duodenalis is a major and global cause of diarrhoeal disease. Eight genetically very distinct groups, known as assemblages A to H, have been recognized in the G. duodenalis species complex, two of which (assemblages A and B) infect humans and other mammalian hosts.

Feline trichomonosis occurs worldwide, with gastrointestinal symptoms such as chronic large-bowel diarrhea and abdominal pain. The inclusion of molecular methods in diagnostic and epidemiological studies has necessitated an effective method for extracting DNA from feces. We tested four extraction commercial kits: ZR Fecal DNA MiniPrep (50 preps) (Zymo Research, Irvine, CA, USA), QIAamp DNA Stool Mini Kit (Qiagen Inc.
