1. Extended-Spectrum Beta-Lactamase Producing Strains of Escherichia Coli Isolated from Avian Cellulitis Lesions
ABSTRACT Avian cellulitis causes significant losses to the poultry industry. Avian-pathogenic Escherichia coli (APEC) is the etiological agent of that disease. This microorganism has zoonotic potential and may act as reservoir of antimicrobial-resistance genes. In this context, the production of extended-spectrum B-lactamase (ESBL) is one of the main antimic

2. Extended Spectrum Beta-Lactamase Production and Biofilm Formation in Salmonella Serovars Resistant to Antimicrobial Agents
ABSTRACT Antimicrobial resistance is a serious public health problem and Salmonella spp. is highly resistant to antimicrobial agents. Biofilms are important in the food industry due to their formation on products, utensils, and surfaces and the difficulty in their removal. The objective of this study was to assess extended spectrum beta-lactamase (ESBL) prod

3. [PROVISIONAL] Genome sequence of Shewanella corallii strain A687 isolated from pufferfish (Sphoeroides spengleri)
Abstract We present here the genome sequence of Shewanella corallii strain A687 isolated from pufferfish Sphoeroides spengleri (Family Tetraodontidae). The assembly consists of 5,215,037 bp and contains 284 contigs, with a G+C content of 50.3%. The genus Shewanella comprises 67 recognized species. These bacteria are Gram-negative, rod-shaped, facultatively a

5. Ocorrência e comportamento antimicrobiano de espécies termotolerantes de Campylobacter isoladas de animais domésticos no sul do Equador
RESUMO: A ocorrência e resistência antimicrobiana de cepas de Campylobacter jejuni e C. coli isoladas de amostras fecais obtidas de cães, suínos, vacas e galinhas no sul do Equador foram determinadas. Das 250 amostras estudadas, 84 (33.6%) foram Campylobacter positivas, sendo C. jejuni mais frequente (78.6%) que C. coli (21.4%) com a exceção das amost

6. SUSCEPTIBILIDADE DE Staphylococcus aureus ISOLADOS DE LEITE CRU A ANTIBIÓTICOS COMERCIAIS
Resumo O leite possui extremo valor na dieta humana e constitui um excelente substrato para o crescimento de grande diversidade de microrganismos, dentre eles o Staphylococcus aureus, frequentemente encontrado no leite cru, e que se destaca como um dos microrganismos mais prevalentes em casos de mastite bovina no mundo. Objetivou-se avaliar a sensibilidade d

7. Prevalence of metallo-β-lactamase-encoding genes among carbapenem-resistant Pseudomonas aeruginosa strains isolated from burn patients in Iran
Abstract Carbapenem-resistant Pseudomonas aeruginosa (CRPA) has been considered a major cause of infection and mortality in burn patients, especially in developing countries such as Iran. One of the most common mechanisms of carbapenem resistance is production of metallo-β-lactamases [(MBLs), including Verona Integron-encoded Metallo-beta-lactamase (VIM), i

8. Clonal relationships, antimicrobial susceptibilities, and molecular characterization of extended-spectrum beta-lactamase-producing Escherichia coli isolates from urinary tract infections and fecal samples in Southeast Iran
Abstract INTRODUCTION: Multidrug-resistant (MDR) Escherichia coli, a species that is a leading cause of urinary tract infections (UTIs) and is a major global public health concern. This study was designed to detect the differences in antibiotic resistance patterns, the production and type of extended spectrum β-lactamases (ESBLs), and the clonal relationsh

9. Detection of multidrug-resistant Pseudomonas aeruginosa harboring bla GES-1 and bla GES-11 in Recife, Brazil
Abstract INTRODUCTION: Pseudomonas aeruginosa, an important pathogen globally, presents several resistance mechanisms. This study aimed to investigate the presence of bla GES in clinical isolates of Pseudomonas aeruginosa obtained from various clinical specimens from patients admitted to three different hospitals in Recife, Brazil. The Guiana extended spect

10. Ceftolozane-tazobactam activity against drug-resistant Enterobacteriaceae and Pseudomonas aeruginosa causing healthcare-associated infections in Latin America: report from an antimicrobial surveillance program (2013-2015)
ABSTRACT This study evaluated the in vitro activity of ceftolozane-tazobactam and comparator agents tested against Latin American isolates of Enterobacteriaceae and Pseudomonas aeruginosa from patients with health care-associated infections. Ceftolozane-tazobactam is an antipseudomonal cephalosporin combined with a well-established β-lactamase inhibitor.A t

11. Drug resistance, AmpC-β-lactamase and extended-spectrum β-lactamase-producing Enterobacteriaceae isolated from fish and shrimp
ABSTRACT The present study aims to detect the production of extended-spectrum beta-lactamases (ESBL) by enterobacteria isolated from samples of fresh shrimp and fish obtained from the retail trade of the city of Sobral, Ceará State, Brazil. All bacterial isolates were submitted to identification and antimicrobial susceptibility testing using aminopenicillin
