BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) has emerged recently worldwide in production animals, particularly pigs and veal calves, which act as reservoirs for MRSA strains for human infection. The study determined the prevalence of MRSA and other resistant strains of S. aureus isolated from the anterior nares of pigs and human handlers on pig farms in Trinidad. METHODS Iso...

Klebsiella pneumoniae, known as a major threat to public health, is the most common factor of nosocomial and community acquired infections. In this study, 50 K. pneumoniae clinical specimens isolated from bronchial, urea, blood, catheter, rectal, bile, tracheal and wound cultures were collected. These isolates were identified and carbapenem resistance was determined via an automated system, CHR...

INTRODUCTION The aim of this study was to determine the prevalence of intestinal carriage of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae and carbapenem-resistant Gram-negative bacilli in the community in Buenos Aires, Argentina. METHODOLOGY Faecal samples from 164 non-hospitalized patients were cultured on CHROMagar KPC and CHROMagar ESBL plates. Isolates resistant to...

OBJECTIVES To determine the prevalence of multidrug-resistant (MDR) Gram-negative bacilli and extended spectrum β-lactamase (ESBL)-producing isolates in stool specimens obtained from patients hospitalized for acute diarrhoea in a French university hospital. METHODS Bacteria in stool specimens were screened for ESBL production on Drigalski agar supplemented with ceftazidime, ESBL CHROMagar(®) ...

Two yeast strains, strains XH 1026 and XH 1164, isolated from the sputum of an intensive care unit patient with acute pneumonia, were originally identified as Candida albicans and C. tropicalis, respectively. Sequence analysis of the 26S rRNA gene D1/D2 domain and the internal transcribed spacer (ITS) region indicated that the two strains represent a novel yeast species closely related to C. ro...

The isolation of non-O157 STEC from food samples has proved to be challenging. The selection of a suitable selective isolation agar remains problematic. The purpose of this study was to qualitatively and quantitatively evaluate six chromogenic agar media for the isolation of STEC: Tryptone Bile X-glucuronide agar (TBX), Rainbow® Agar O157 (RB), Rapid E. coli O157:H7 (RE), Modified MacConkey Aga...

AIM We aimed to determine the prevalence and associated risk factors for nasal methicillin-sensitive and methicillin-resistant Staphylococcus aureus (MSSA/MRSA) carriage among patients admitted to a chest clinic of a tertiary care hospital in this study. MATERIALS AND METHODS Nasal samples were taken from anterior nares were cultured in CHROMagar S. aureus plates, MRSA was determined by disc ...
