Effect of Feed Processing on Broiler Performance
It is well recognized that feed represents the most significant cost of broiler production. Most production costs estimates range from 60-70% as being feed costs. Certainly, the major portion of feed costs is for the ingredients used. However, the cost of feed processing represents a significant portion of feed costs and likely gives the greatest opportunity for influencing broiler performance ...
متن کاملSerratia marcescens.
Over the last 30 years, Serratia marcescens has become an important cause of nosocomial infection. There have been many reports concerning the identification, antibiotic susceptibility, pathogenicity, epidemiological investigations and typing of this organism. Accurate identification is important in defining outbreaks. The API 20E system has been used widely, but is not individually satisfactor...
متن کاملSerratia marcescens
The nucleotide sequence of the proBA operon from a proline-hyperproducing mutant of Serratia marcescens was determined. Two base substitutions were found: one in theproBstructura1 gene, coding for y-glutamyl kinase (GK), and a second one in the promoter region of the operon. The former base substitution led to a change of the predicted amino acid at position 117 from an alanine to a valine in G...
متن کاملA Strain of Serratia marcescens Pathogenic for Larvae of Lymantria dispar: Infectivity and Mechanisms of Pathogenicity
The ED,?, of a strain of Serratia marcescens for microinjected instar III and IV gypsy moth larvae was 7.5 and 14.5 viable cells, respectively. Percentage and rate of mortality were found to be highly variable among replicates of the same instar and between instars in free-feeding bioassays. Mortality in second instar larvae occurred before ecdysis, whereas practically no mortality occurred in ...
متن کاملSerratia marcescens meningitis.
A case of Serratia marcescens meningitis in a 66-year-old man is reported. The infection occurred 4 weeks after apparently successful otic surgery, and a nidus of infection in the middle ear was established at autopsy. This is the second case of S. marcescens meningitis following ear surgery reported in the English-language literature.
