Between July 2008 and May 2010, we conducted a trophic study on 12 Brazilian wild carnivore species through their faecal analysis in a silvicultural landscape at Angatuba municipality, southern São Paulo state. Predator faeces was identified by morphology, predator hair, and surrounding tracks; prey remnants within faeces were used for morphological identification of the prey. Among the recovered ectoparasites, there were 89 specimens of six tick species in 21 (4.0%) out of 523 analysed samples. Ticks were identified to species level, based on external morphological characters, as following: adults of Amblyomma ovale and Amblyomma sculptum; nymphs of Amblyomma brasiliense, Amblyomma calcaratum, Amblyomma dubitatum, A. ovale, and Ixodes schulzei; and larvae of Amblyomma sp. and Ixodes sp. Generally, the recovered immature ticks were associated with consumed prey (small birds or small mammals), whereas adults were associated with the predator itself, ingested during its self-grooming. Our data show that faeces is an additional information source on ticks in Brazil and which may provide information on ectoparasite-predator-prey interactions.

Objectives: To assess the therapeutic effects and safety of Tongxie Yaofang (TXYF) granules vs placebo as an alternative treatment for diarrhoea-predominant irritable bowel syndrome (IBS-D). We hypothesised that TXYF would improve clinical responses among patients with IBS-D.
Design: A randomised, double-blind, placebo-controlled, phase II, superiority trial.

Objectives: Faecal microbiota transplantation (FMT) is an established treatment for recurrent Clostridioides difficile infection (R-CDI). This study aimed to identify calprotectin and microbiome characteristics as potential biomarkers of FMT success.
Methods: We conducted a prospective study of patients who underwent oral FMT (single dose of 4-5 capsules) for R-CDI (January 2018 to December 2022).

Electronic address:
Pigeon adenovirus type 1 predominantly infects pigeons under 12 months of age (mainly 3-5 months old), causing major clinical symptoms such as vomiting, dehydration, and discharge of thin yellow feces. In February 2023, an outbreak of a pathogen with symptoms similar to pigeon adenovirus infections occurred on a pigeon farm in Shandong Province, which was eventually identified as pigeon adenovirus type 1. In this study, a strain of PiAdV-1 was isolated from naturally infected pigeons and named pigeon-adenovirus-1-isolate-CH-SD-2023, and the hexon gene sequence as amplified and analyzed using polymerase chain reaction (PCR).

Background: The intestinal microbiota regulates normal brain physiology and the pathogenesis of several neurological disorders. While prior studies suggested that this regulation operates through immune cells, the underlying mechanisms remain unclear. Leveraging two well characterized murine models of low-grade glioma (LGG) occurring in the setting of the neurofibromatosis type 1 (NF1) cancer predisposition syndrome, we sought to determine the impact of the gut microbiome on optic glioma progression.
