Genomic analysis of fluoroquinolone-resistant Leclercia adecarboxylata carrying the ISKpn19-orf-qnrS1-ΔIS3-bla module in a synanthropic pigeon, Brazil.

Objectives: The aim of this study was to perform a genomic investigation of a multiple fluoroquinolone-resistant Leclercia adecarboxylata strain isolated from a synanthropic pigeon in São Paulo, Brazil.

Methods: Whole-genome sequencing was performed using an Illumina platform, and in silico deep analyses of the resistome were performed. Comparative phylogenomics was conducted using a global collection of publicly available genomes of L.

One health clones of multidrug-resistant carried by synanthropic animals in Brazil.

WHO priority pathogens have disseminated beyond hospital settings and are now being detected in urban and wild animals worldwide. In this regard, synanthropic animals such as urban pigeons () and rodents (, and ) are of interest to public health due to their role as reservoirs of pathogens that can cause severe diseases. These animals usually live in highly contaminated environments and have frequent interactions with humans, domestic animals, and food chain, becoming sentinels of anthropogenic activities.

An Outbreak in Pigeons Caused by the Subgenotype VI.2.1.2 of Newcastle Disease Virus in Brazil.

Newcastle disease virus (NDV) can infect over 250 bird species with variable pathogenicity; it can also infect humans in rare cases. The present study investigated an outbreak in feral pigeons in São Paulo city, Brazil, in 2019. Affected birds displayed neurological signs, and hemorrhages were observed in different tissues.
