The scientific information regarding staphylococci in procyonids is scarce. Hence, the aim of this study was to evaluate the frequency, distribution, and pattern of antimicrobial resistance of staphylococcal species isolated from free-roaming coatis () in an urban park in Belo Horizonte, Minas Gerais, Brazil. Rectal swabs from 55 free-living coatis were plated onto mannitol salt agar for isolating staphylococci, and species were identified using matrix-assisted laser desorption/ionization-time of flight mass spectrometry, polymerase chain reaction (PCR) of , and sequencing of 16S rRNA and when needed. Antimicrobial susceptibility was investigated using the disk diffusion method, and the presence of the gene was investigated by PCR. A total of 72.7% of the animals tested positive for staphylococci. Nine different species were identified, and (60.4%) and (20.9%) were the most frequently isolated species. Most of the isolates were susceptible to most of the antimicrobials evaluated, with a resistance pattern seen for penicillin (13.9%). One isolate was multidrug-resistant (MDR). The present study suggests that coatis are natural hosts of and and, despite living in a heavily anthropized environment, the spp. isolates showed a low incidence of drug resistance.

The pathogenic oomycete Pythium insidiosum causes a fatal infectious illness known as pythiosis, impacting humans and certain animals in numerous countries in the tropics and subtropics. Delayed diagnosis is a primary factor contributing to the heightened morbidity and mortality associated with the disease. Several new serodiagnostic methods have been developed to improve the identification of pythiosis.

The Mycobacterium avium complex (MAC) is a group of closely related nontuberculous mycobacteria that can cause various diseases in humans. In this study, genome sequencing, comprehensive genomic analysis, and antimicrobial susceptibility testing of 66 MAC clinical isolates from King Chulalongkorn Memorial Hospital, Bangkok, Thailand were carried out. Whole-genome average nucleotide identity (ANI) revealed the MAC species distribution, comprising 54 (81.

Purpose: To understand the mechanisms of carbapenem-resistant Klebsiella pneumoniae (CRKP) from Tanzania and characterize the genomes carrying the carbapenemase genes.
Methods: Clinical CRKP isolates were selected from ongoing antimicrobial-resistant surveillance at Muhimbili National Hospital, Dar es Salaam, Tanzania. Whole-genome sequencing was performed utilizing Illumina and Nanopore platforms.

The rise of antimicrobial-resistant microorganisms (AMR) poses a significant global challenge to human health and economic stability. In response, various scientific communities are seeking safe alternatives to antibiotics. This study comprehensively investigates the antibacterial effects of red dye derived from Monascus purpureus against three bacterial pathogens: Salmonella typhimurium ATCC14028, Escherichia coli ATCC8739, and Enterococcus faecalis ATCC25923.
