Aims: To develop an improved method for the detection of Bifidobacterium adolescentis as an indicator of human faecal pollution.
Methods And Results: Bifidobacterium medium (BFM) was identified as the optimal medium for the recovery of bifidobacteria from human effluent. Dilutions of faeces and effluent from both humans and animals were filtered, grown on BFM and human specific B. adolescentis identified via colony hybridization with a digoxigenin (DIG)-labelled oligonucleotide probe.
Conclusions: The combination of BFM with colony probing allows the detection of B. adolescentis, a specific indicator of human faecal pollution.
Significance And Impact Of The Study: It is now technically feasible to use B. adolescentis as indicators of human faecal pollution, and studies to examine the survival and appropriateness of bifidobacteria in this role can be initiated.

Mammarenaviruses (genus Mammarenavirus, family Arenaviridae) are rodent-borne zoonotic viruses consisting of 52 viral species, including ten that are pathogenic to humans. Currently, only two endemic mammarenavirus species are known in Europe: the human pathogenic Mammarenavirus choriomeningitidis (LCMV) and the recently discovered hedgehog-origin Mammarenavirus mecsekense (MEMV). In this study, 59 faecal specimens from Northern white-breasted hedgehogs (Erinaceus roumanicus) from different geographic regions in Hungary were investigated for mammarenavirus presence and complete genome characterization using newly designed screening primers by RT-semi-nested PCR and sequencing methods.

Background: The gut microbiota, or microbiome, is essential for human health. Early-life factors such as delivery mode, diet, and antibiotic use shape its composition, impacting both short- and long-term health outcomes. Dysbiosis, or alterations in the gut microbiota, is linked to conditions such as allergies, asthma, obesity, diabetes, inflammatory bowel disease, and necrotizing enterocolitis in preterm infants.

Background: Knowledge of the complex interplay between gut microbiota and human health is gradually increasing as it has just recently been a field of such great interest.
Summary: Recent studies have reported that communities of microorganisms inhabiting the gut influence the immune system through cellular responses and shape many physiological and pathophysiological aspects of the body, including muscle and bone metabolism (formation and resorption). Specifically, the gut microbiota affects skeletal homeostasis through changes in host metabolism, the immune system, hormone secretion, and the gut-brain axis.

Toxoplasma gondii, an obligate intracellular protozoan, infects almost all warm-blooded animals and humans, with felines serving as its sole definitive hosts. Cats release T. gondii oocysts into the environment through feces, contributing to environmental contamination that can lead to toxoplasmosis in humans upon exposure through ingestion of contaminated food, water, or soil.

South American camelids (SACs), particularly llamas (Lama glama) and alpacas (Vicugna pacos) are gaining popularity in Europe. Initially valued for their fiber and land management capabilities, these animals are now also kept for animal therapy, outdoor activities, and as companion animals. Despite their close interactions with humans and other animals, there is limited research on the transmission of microbes or antimicrobial resistance genes from SACs.
