Little is known about how generosity of insurance and population characteristics affect quantity or appropriateness of antibiotic use. Using insurance claims for antibiotics from 5765 non-elderly people who lived in six sites in the United States and were randomly assigned to insurance plans varying by level of cost-sharing, we describe how antibiotic use varies by insurance plan, diagnosis and...

Radioimmunoassay with calf and cow vitreous humour-I125 and rabbit antivitreous humour serum has been employed to investigate the immunological cross-reactivity of vitreous humour with bacterial and mammalian tissue antigens. Klebsiella ultrasonicate preparation at a dose fo 10 000 micrograms/ml was found to inhibit the binding of vitreous humour by 25-100% (p less than 0.001), compared with an...

Seventy five eye drops samples were collected from different pharmacies in Cairo, Egypt. Out of 75 tested samples, 58 (77.3%) are contaminated with bacterial growth when cultured on MYP medium. The bacterial count ranging from 1.0 CFU/ml to 6.0x10 CFU/ml. The microscopic examination indicated that 2 57 out of 133 isolates are Gram positive, spore forming bacilli. From 58 positive samples 32 sam...

Efflux pumps are vital bacterial components, and research has demonstrated that some plant compounds such as pheophorbide a (php) possess efflux pump inhibitor (EPI) activity. This study determined the quantity of php present in feces as an indicator of EPI activity. Feces were collected from different species of animals fed a variety of feeds. The chlorophyll metabolites php and pyropheophorbi...

The effect of erythromycin on activated sludge bacteria according to their Gram type was investigated with 3-dimensional Confocal Laser Scanning Microscopy (CLSM) time-lapse imaging. The fluorescent stains SYTOX Green and Texas Red-X conjugate of wheat germ agglutinin stained dying bacteria and Gram(+) bacteria respectively. Time-lapse imaging allowed an understanding of the staining mechanism ...

The kinetics of biodegradation of palm-derived fatty methyl and ethyl esters (Elaeis guineensis biodiesel) by a wild-type aerobic bacterial population was measured at 20 degrees C, as the rate of oxygen uptake by a manometric technique. The methyl and ethyl biodiesels were obtained by potassium-hydroxide catalysed trans-esterification of palm oil, respectively. The bacterial flora included the ...

The lumen of the gastrointestinal tract is home to an enormous quantity of different bacterial species that thrive in an often symbiotic relationship with the host. It is the principal source of microbial products because of its massive bacterial load. Injury to the immune component of the gastrointestinal mucosal surface, along with damage to the intestinal epithelial microenvironment with its...

Release factor 3 (RF3) is a GTPase found in a broad range of bacteria where it is thought to play a critical "recycling" role in translation by facilitating the removal of class 1 release factors (RF1 and RF2) from the ribosome following peptide release. More recently, RF3 was shown in vitro to stimulate a retrospective editing reaction on the bacterial ribosome wherein peptides carrying mistak...
