| Abstract Aims We sought to characterize the antibiotic susceptibility of strains of Stenotrophomonas maltophilia isolated from clinical samples, and the role of Stenotrophomonas maltophilia biofilm in antibiotic resistance. Methods Fifty-one clinical Stenotrophomonas maltophilia isolates were obtained from patients with nosocomial infection in the surgical wards and ICUs of six general hospitals in Tianjin, China. In vitro models of Stenotrophomonas maltophilia biofilms were established and confirmed by scanning electron microscopy and fluorescence microscopy with silver staining. The minimal inhibitory concentrations and biofilm inhibitory concentrations of commonly used antibiotics were determined. Results 47 of 51 strains were resistant to three or... |

| One hundred and fifty-one methicillin-resistant z (MRSA) strains have been isolated from patients admitted in tertiary care hospitals in two metropolitan areas (Campinas City and Ribeirão Preto City) in the southeast region of Brazil and analyzed through PCR-based techniques [(PCR amplification of spa, coa, and housekeeping genes (arcC, aroE, gmk, pta, tpi, yqiL)] and further restriction fragment typing of coa and of housekeeping genes. The heterogeneity of spa gene was determined directly by agarose gel electrophoresis migration. The results obtained indicate the existence of three (A, B, C) main clusters. Since the strain distribution in these three clusters is much characteristic, it denotes the existence of three main clones. All strains isolated in... |

| ABSTRACT: The present study aimed to describe and characterize a nosocomial outbreak caused by a multidrug resistant Salmonella Typhimurium in hospitalized calves at a veterinary medical teaching hospital from Brazil. Sixty-three (96.9%) calves showed lethargy, hyperthermia and profuse diarrhea and despite treatment, 26 (41.2%) animals died. Five animals were necropsied and stool samples of six calves were collected. The isolated strains were subjected to antimicrobial susceptibility test by disc-difusion method and were fingerprinted by ERIC-PCR. Macroscopic lesions suggestive of salmonellosis, such as fibrinonecrotic enteritis and hepatosplenomegaly were observed. Salmonellosis was confirmed by isolation of S. Typhimurium from stool samples and organs... |
