Native California soils are selective reservoirs for multidrug-resistant bacteria.

Soil bacteria can exhibit extensive antibiotic resistomes and act as reservoirs of important antibiotic resistance traits. However, the geographic sources and evolutionary drivers of resistance traits are poorly understood in these natural settings. We investigated the prevalence, spatial structure and evolutionary drivers of multidrug resistance in natural populations of Bradyrhizobium, a cosm...

Seagulls and Beaches as Reservoirs for Multidrug-Resistant Escherichia coli

A variety of extended-spectrum Beta-lactamase-producing Escherichia coli isolates, with a high rate of cefotaximase-15 resistance, were identified in seagull feces from Porto, Portugal, beaches. Beaches may therefore present a risk to public health because of the potential pathogen-spreading capacity of migratory birds.

Prospects for Success in Inhibiting the Growth of Multidrug-resistant Bacteria with Paromomycin

Streptomyces is the most important bacterial genus known to produce secondary antibiotic compounds. Considering the speed of bacterial resistance spread, it becomes more important to study less used compounds. Aminoglycosides disrupt the function of the target microorganism by acting on the protein-synthesis process. Paromomycin is an aminoglycoside that acts on a wide range of gram-positive, g...

Aquariums as Reservoirs for Multidrug-resistant Salmonella Paratyphi B

Multidrug-resistant Salmonella enterica serovar Paratyphi B dT+ isolates from patients with gastroenteritis were identical with isolates from their home aquariums. Matched isolates had identical phage types, XbaI and IS200 profiles, and Salmonella genomic island 1 (SGI1). Ornamental fish tanks are reservoirs for SGI1-containing S. Paratyphi B dT+.

Multidrug-Resistant Bacteria in Southeastern Austria

To the Editor: In many parts of the world, the proportions of methicil-lin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant en-terococci, and extended-spectrum β-lactamase (ESBL)–producing organisms in the family Enterobacteriaceae have increased remarkably during recent years (1). However, proportions of antimicrobial drug resistance vary substantially at national and regional leve...
