The inverted repeats of Tn5, which have identical restriction endonuclease cleavage patterns, have different functional properties. They differ with respect to RNA polymerase binding, full promotion of neomycin resistance, the polypeptides coded for by the repeats and their function in the transposition process. There is a week RNA polymerase binding site present in one repeat and not in the ot...

Background Throughout literature, positive patch tests to nickel were found in 8.0–51.5% patients with eczema and in 5.9– 27.8% general population, the respective figures for neomycin being 0.0–40.0% and 0.0–2.9%, respectively. As these ranges for eczema patients and general population overlap, it is not clear how strong is the association between the disease and contact sensitization to respec...

For the first time in natural O-glycosides, a large amount of non-exo-anomeric conformation is experimentally detected, in solution.

187 commercial checken flocks affected with respiratory diseases were examined for ornithobacterium rhinotracheale isolation. the bacterium was isolated from 105 (56.2%) poultry flocks. drug sensitivity test using standard disk diffusion technique was performed with 19 antibiotics. all the isolates were susceptible to tiamulin and most of them were susceptible to chloramphenicol and linco-spect...

Seven post-operative wounds were infected with a strain of Staphylococcus aureus, probably acquired from a theatre orderly who suffered from a dry generalized eczema. The orderly was a nasal and heavy skin carrier, and was shown to be a disperser of the epidemic strain. Infection was probably acquired from airborne contamination in the operating theatre, since the orderly did not scrub-up. The ...

The ability of various subsets of poultry intestinal microbiota to protect turkeys from colonization by Campylobacter jejuni was investigated. Community subsets were generated in vivo by inoculation of day-old poults with the cecal contents of a Campylobacter-free adult turkey, followed by treatment with one antimicrobial, either virginiamycin, enrofloxacin, neomycin, or vancomycin. The C. jeju...
