Third-generation cephalosporin resistance in Shigella sonnei, Argentina.
نویسندگان
چکیده
Shigella sonnei resistant to cefotaxime (but not to ceftazidime) was isolated for the first time in stool samples from a pediatric patient with vomiting and bloody diarrhea in northern Argentina. Microbiologic and biochemical tests confirmed the presence of an extended spectrum beta-lactamase displaying an apparent isoelectric point value of 8.2.

Identification of Shigella species and their antibiotic resistance patterns from dysenteric patients in Baradaran Rezaei hospital of Damghan, Northeast of Iran
Shigella is a major cause of dysentery across the world. Appropriate antibiotic treatment of shigellosis depends on resistance patterns. The present study was conducted to identify Shigella species and their antibiotic resistance patterns among dysenteric patients in Rezaei Hospital of Damghan. Isolation of Shigella species was conducted by specific culture medium and biochemical tests. The Shi...
متن کاملEpidemic and virulence characteristic of Shigella spp. with extended-spectrum cephalosporin resistance in Xiaoshan District, Hangzhou, China
BACKGROUND Shigellae have become increasingly resistant to the extended-spectrum cephalosporin (ESC) worldwide and pose a great challenge to anti-infection treatment options. The purpose of this study was to determine the resistance, cephalosporin resistance mechanisms, virulence characteristic and genotype of ESC-resistant Shigella. METHODS From 2008 to 2012, Shigella isolates collected from...

OBJECTIVES In this study, we wanted to assess the level of antimicrobial resistance, the presence of genes encoding resistance to cephalosporins and plasmid-mediated quinolone resistance (PMQR), and genetic relatedness among Shigella isolates obtained from Iranian patients. METHODS A total of 44 Shigella isolates were collected from Iranian patients admitted to Milad Hospital, Tehran, Iran, d...
متن کاملCase Report Emergence of Resistance to Third-Generation Cephalosporin in Shigella—A Case Report
The emergence of ciprofloxacin resistance in Shigella has shifted the attention to cephalosporins. The first occurrence of third generation cephalosporin-resistant Shigella flexneri was from France. This article reports the first case of cephalosporin-resistant S. flexneri from India. A 12-month-old child was admitted for a 20-day episode of loose stools, non-fetid, with mucus and blood. The st...
متن کاملMolecular characterization of ESBL-producing Shigella sonnei isolates from patients with bacilliary dysentery in Lebanon.
BACKGROUND Emergence of extended-spectrum beta-lactamases (ESBLs) in Shigella species imparting resistance to third-generation cephalosporins is a growing concern worldwide. The aim of this study is to molecularly characterize the newly emerging beta-lactam resistant Shigella sonnei, specifically ESBLs in Lebanon, and compare them to beta-lactam sensitive isolates. METHODOLOGY We compared fiv...
