The isolation of multidrug-resistant (MDR) bacteria from the urinary tracts of pets is increasingly common, particularly in animals with concurrent health conditions. (PA) is one of the most significant antimicrobial-resistant bacteria affecting cats and dogs within the European Union (EU). This study aims to review the prevalence and antimicrobial resistance patterns of PA isolated from urine samples of small animals globally. This pathogen is known for its opportunistic infections and is a significant concern in veterinary medicine due to its inherent resistance to multiple antibiotics and its ability to acquire additional resistance mechanisms. This review seeks to enhance educational initiatives regarding the management of emerging MDR bacteria.

Background: Infection is a leading cause of death after pediatric heart transplants (PHTs). Understanding of common pathogens is needed to guide testing strategies and empiric antibiotic use.
Methods: We conducted a 3-center retrospective study of PHT recipients ≤18 years old presenting to cardiology clinics or emergency departments (EDs) from 2010 to 2018 for evaluation of suspected infections within 2 years of transplant.

Evolution of gene expression frequently drives antibiotic resistance in bacteria. We had previously (Patel and Matange, , 2021) shown that, in , mutations at the locus were beneficial under trimethoprim exposure and led to overexpression of dihydrofolate reductase (DHFR), encoded by the gene. Here, we show that DHFR levels are further enhanced by spontaneous duplication of a genomic segment encompassing and spanning hundreds of kilobases.

Gardnerella vaginalis is the most frequently identified bacterium in approximately 95% of bacterial vaginosis (BV) cases. This species often exhibits resistance to multiple antibiotics, posing challenges for treatment. Therefore, there is an urgent need to develop and explore alternative therapeutic strategies for managing bacterial vaginosis.

Novel treatment options are needed for the gastric pathogen due to its increasing antibiotic resistance. The vitamin K analogue menadione has been extensively studied due to interest in its anti-bacterial and anti-cancer properties. Here, we investigated the effects of menadione on growth, viability, antibiotic resistance, motility and gene expression using clinical isolates.

Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is a leading cause of sight-threatening infections in the US. These strains pose a significant challenge in managing ocular infections, as they frequently exhibit resistance to first-line empirical antibiotics. To assess the potential of bacteriophages as innovative topical therapies for treatment of recalcitrant ocular infections, we evaluated the in vitro antimicrobial activity of a set of anti-S.
