| Shigella spp are Gram-negative, anaerobic facultative, non-motile, and non-sporulated bacilli of the Enterobacteriaceae family responsible for "Shigellosis" or bacillary dysentery, an important cause of worldwide morbidity and mortality. However, despite this, there are very few epidemiological studies about this bacterium in Brazil. We studied the antibiotic resistance profiles and the clonal structure of 60 Shigella strains (30 S. flexneri and 30 S. sonnei) isolated from shigellosis cases in different cities within the metropolitan area of Campinas, State of São Paulo, Brazil. We used the following well-characterized molecular techniques: enterobacterial repetitive intergenic consensus, repetitive extragenic palindromic, and double-repetitive... |

| Shigella spp., the human pathogen responsible for shigellosis, is highly infectious even at low levels. The incidence rate of shigellosis varies with geographical distribution, location human development index, and age groups, being higher among children aged under 5 years. In Brazil, a few works indicate that shigellosis cases are underestimated, with S. flexneri and S. sonnei strains being the major agents responsible for the shigellosis cases. The present study used pulsed field gel electrophoresis (PFGE) to investigate the molecular epidemiology of 119 strains of S. sonnei and S. flexneri isolated from shigellosis cases that occurred in the metropolitan areas of Ribeirão Preto and Campinas Cities, São Paulo Sate, southeast Brazil. The results indicated... |

| The aims of this study were to investigate drug resistance rates, types of extended spectrum beta lactamases (ESBLs), and molecular epidemiological characteristics of 43 Shigella sonnei isolates. Ampicillin-sulbactam, amoxicillin-clavulanate, chloramphenicol, and ciprofloxacin were the most active antibiotics. Five isolates harbored blaSHV-12, blaTEM-1 and blaCTX-M-15. More than 90% of the isolates had an indistinguishable pulsotype. |
