The determination of members of the genus Salmonella present in small numbers in egg solids has always been somewhat uncertain. Among other things, the nature of the product tends to reduce the selectivity of the various media used for their detection. Also some of the enrichment media tend to inhibit the growth of certain types of Salmonella (Ayres, 1953; Banwart and Ayres, 1953; Hurlev and Ay...
The present study was conducted to investigate the effects of different levels of pomegranate by- product (PBP) on performance, egg quality and blood parameters in laying hens. A total of 144 Bobze layer hens from 44 to 56 weeks during 12 weeks were randomly assigned into 4 treatments including 0 (control, corn and soy bean meal), 4, 8 and 12% of PBP, with 4 replicates and 9 layers in each. Res...
Egg quality is a complex biological trait and a major determinant of reproductive fitness in all animals. This study delivered the first proteomic portraits of egg quality in zebrafish, a leading biomedical model for early development. Egg batches of good and poor quality, evidenced by embryo survival for 24 h, were sampled immediately after spawning and used to create pooled or replicated samp...
A collaborative study was conducted to compare a new enrichment procedure for the TECRA Salmonella Visual Immunoassay (TSVIA) with the reference method given in the U.S. Food and Drug Administration's Bacteriological Analytical Manual (7th Ed.). Three food types (milk powder, pepper, and soy flour) were analyzed in Australia and 3 food types (milk chocolate, dried egg, and raw turkey) were anal...
BACKGROUND Egg allergy is one of the most common food allergies of childhood. There is a lack of information on the immunologic basis of egg allergy beyond the role of IgE. OBJECTIVE To use transcriptional profiling as a novel approach to uncover immunologic processes associated with different phenotypes of egg allergy. METHODS Peripheral blood mononuclear cells (PBMCs) were obtained from e...
Species-specific differences in the responses of egg-laying mosquitoes (Diptera: Culicidae) to the presence of fish exudates in oviposition sites in laboratory bioassays have been related to the likelihood of encountering mosquito-eating fish in natural oviposition sites. We examined the responses of egg-laying mosquitoes to the presence of larvivorous fish in oviposition sites to test this hyp...
Enrichment of eggs with folate is possible when dietary folic acid levels are increased. However, development of optimal strategies for the production of folate-enriched eggs requires knowledge as to differences due to strain of bird and a greater understanding of the factors limiting egg folate deposition. To this end, a study was designed to determine the response of two leghorn strains that ...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
Microbial food safety of eggs has not been thoroughly investigated in Egypt. Pseudomonas species are among the most ubiquitous bacteria in the environment that may also contaminate eggs. To investigate the microbial burden of Pseudomonas species in eggs, one hundred composite samples (6 eggs in each) of table hen and duck eggs were prepares after they were collected from different shops and sup...
