Methods Microbiological records of patients with E. coli bacteraemia were linked with patient data to determine their characteristics, whether CA or HA, and if the E. coli produced ESBL. Blood cultures taken within 2 days of admission were defined as CA, 2 days or more after admission as HA and a new episode if greater than 2 weeks between positive blood cultures. E. coli ESBL was defined by re...

MICs of 21 beta-lactams were determined by agar dilution against 283 penicillin-susceptible (pen-S), 122 intermediate (pen-I) and 23 fully penicillin-resistant (pen-R) pneumococci. MICs of all beta-lactams increased with increasing MICs of penicillin. Clometocillin was the most active penicillin against pen-I or pen-R pneumococci. All oral cephalosporins except cefuroxime and cefpodoxime were l...

INTRODUCTION Vibrio (V.) parahaemolyticus has endemically established in Chilean sea shores, causing outbreaks every year, with an important number of cases. In order to know the genetic relationship, genotype dominance and antibiotic resistance of isolates obtained from two outbreaks, this study characterized 110 strains isolated from environmental and clinical samples in years 2005 and 2007 i...

This study focused on the use of antibiotics on small, medium and commercial-sized dairy farms in the central region of Zambia and its relationship to antibiotic resistance in Escherichia coli. A stratified random sample of 104 farms was studied, representing approximately 20% of all dairy farms in the region. On each farm, faecal samples were collected from a random sample of animals and a sta...

OBJECTIVES We characterized mechanisms of resistance to oxyimino-cephalosporins in Escherichia coli isolated from raw chicken meat imported into the UK from South America, to ascertain whether this foodstuff contributes to the dissemination in the UK of extended-spectrum β-lactamase (ESBL)-producing E. coli belonging to the international uropathogenic ST131 clone. METHODS Sampling and collect...

Objective: The objective of the present study was to collect different Lactic acid bacterial strains from culture collection centers and screen their functional probiotic characteristics such as acid tolerance, bile tolerance, antibacterial activity and antibiotic sensitivity for their commercial use. Materials and Methods: Acid and bile tolerence of selected LAB(Lactic acid bacteria) was deter...

At present scenario, the multi drug resistant microorganisms (MDRO’s) causes various life threatening infections which even leads to death of an infected individual. A broad range of microorganisms, such as Staphylococcus aureus and Pseudomonas aeruginosa as well as Enterobacteriaceae like Escherichia coli and Klebsiella pneumoniae were highly resistant to commonly used antibiotics. Resistance ...
