Metagenomic profiling of pigeon faecal microbiota: insights into microbial diversity, pathogens, and antimicrobial resistance genes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Rock pigeon (Columba livia) droppings harbour diverse microorganisms, including potential pathogens. This study utilised shotgun metagenomic sequencing to analyse pigeon faecal microbiota and identify potential pathogens. Fresh faecal samples (273) were collected within Universiti Tunku Abdul Rahman Kampar campus, Malaysia. Total genome and viral genomes were extracted and sequenced using the Illumina NovaSeq 6000 platform. Taxonomic assignment, antimicrobial resistance (AMR) gene detection, and viral genome assembly were conducted using the CZ ID platform. The microbial diversity was predominated by bacteria, followed by eukaryotic viruses and fungi, with no archaea were detected. Pseudomonadota (84.44%) and Bacillota (15.26%) were the predominant bacterial phyla, with Pseudomonadota being 5.5 times more abundant, indicating potential enteric-like issues within the pigeon flocks. Approximately 5.11% of the bacterial community (comprising 38 species), was identified as potential pathogens, could primarily cause human enteric and respiratory infections. Nineteen AMR genes were detected, primarily associated with pathogenic Shigella, Salmonella, and Klebsiella. The presence of AMR genes and possible co-circulation among pathogenic bacteria impose the risk of emergence of multidrug-resistant bacteria. Nine avian virus species were detected. The predominant DNA virus, pigeon circovirus (73.23%) could cause immunosuppression, predisposing pigeons to secondary infections by E. coli, K. pneumoniae, and rotaviruses. The predominant RNA virus, rotaviruses (80.43%) could cause enteric diseases in both humans and birds. The fungal community comprised Kazachstania (94.11%) and Trichosporon (3.56%), with K. bovina and T. asahii identified as human pathogens. This study highlights the compelling need for effective pigeon control in dining areas, ventilation systems, and healthcare facilities.
