Phenotypic and genotypic detection of antibiotic-resistant bacteria in fresh fruit juices from a public hospital in Rio de Janeiro.

Gram-negative bacteria are worrisome because they are becoming resistant to many antibiotic available options, mainly in hospital environment. Several studies have noted the presence of bacteria producing extended-spectrum beta-lactamase, with the presence of antibiotic-resistance genes in fresh vegetables and fruits. This study aimed to detect the presence of phenotypic and genotypic resistance in eight samples of fresh fruit juices served to patients admitted to a hospital in Rio de Janeiro.
