Twelve laboratories in different parts of Britain each supplied approximately 80 consecutive urinary bacterial isolates from community patients. All strains were identified by a central laboratory, where sensitivity to a variety of orally administered antimicrobials was determined by microtitre broth dilution. 65.1% of isolates were Escherichia coli, 23.4% 'coliforms' other than E. coli, 4.6% P...

In critically ill patients, catheter-related bloodstream infections (CRBSIs) are associated with increased mortality, length of stay in the ICU and extra costs. The relative risk of infection can be best determined by analyzing rates of catheter-related bloodstream infections per 1000 catheter-days. Coagulase-negative staphylococci, Staphylococcus aureus and Candida spp are the pathogens found ...

b a ckground: the brown-banded cockroach, supella longipalpa is known as a carrier of pathogenic bacteria in urban environments, but its role is not well documented regarding the carriage of antibiotic-resistant pathogenic bacte- ria in iran. the aim of this study was to determine the resistance bacteria isolated from the brown-banded cockroach in ahvaz, south west of iran. m e t hods: totally ...

Groundnut paste is frequently associated with food-borne illness due to contamination traceable food handlers, processing materials as well environmental conditions and this therefore necessitated the microbiological quality examination of groundnut paste. The percentage occurrence bacteria isolates moisture content were determined using standard laboratory techniques. pastes was between range ...

Bacteria have special bio-mechanism to resist toxic heavy metals. This study investigated metal tolerance potentials of bacterial isolates from solid waste dumping sites (Abaji, Bwari, Gosa, Gwagwalada, Kuje, and Kwali) in Abuja, Nigeria. Soil samples were randomly collected each location using soil augers at depths 0 – 15, 15 35 45 cm. They analyzed bacteriologically cultural/biochemical techn...

Introduction: Multi-drug resistant Gram negative bacilli are increasingly being isolated from hospitals throughout the world. The aim of this study was to determine the antimicrobial susceptibility profile of Gram negative bacterial isolates obtained from various clinical samples of patients admitted in different ICUs and wards of a super-specialty hospital during 2014. Materials and Methods: A...

The in vitro antimicrobial and antioxidant activities of the exopolysaccharide (EPS) extracted from yoghurt starter were investigated. Antimicrobial activity tests were carried out using disc diffusion methods with Escherichia coli, Staphylococcus aureus and Streptococcus D, Proteus spp and the yeast of Candida albicans. The antioxidant properties were evaluated using the test of DPPH free radi...

CTX-M enzymes, the plasmid-mediated cefotaximases, constitute a rapidly growing family of extended-spectrum β-lactamases (ESBLs) with significant clinical impact. CTX-Ms are found in at least 26 bacterial species, particularly in Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis. At least 109 members in CTX-M family are identified and can be divided into seven clusters based on thei...

The intention of this study was to identify the bacterial pathogens infecting Oreochromis niloticus (Nile tilapia) and Clarias gariepinus (African catfish), and to establish the antibiotic susceptibility of fish bacteria in Uganda. A total of 288 fish samples from 40 fish farms (ponds, cages, and tanks) and 8 wild water sites were aseptically collected and bacteria isolated from the head kidney...

The activity of a new semisynthetic penicillin, carbenicillin, was determined against 241 strains of gram-negative bacilli with the tube-dilution technique. Of 143 strains of Pseudomonas sp., 99 had a minimal inhibitory concentration of 200 to 300 mug/ml. The majority of strains of Escherichia coli and Proteus spp. were sensitive to this antibiotic, with minimal inhibitory concentrations of 25 ...
