Methods for Inoculation and Recovery of Salmonella from Chicken Eggs

Comparison of homogenization methods for recovering Salmonella Enteritidis from eggs.

For Salmonella Enteritidis (SE) detection, shell eggs have been homogenized with stomachers, with electric blenders, and by hand massaging. However, to date, there have been no published reports addressing whether the method of homogenization affects the recovery of SE from raw eggs. Three inoculum levels (10, 126, and 256 SE cells per pool of 10 eggs) were used to conduct three experiments. Th...

Recovery in embryonated chicken eggs of viable but non-culturable Salmonella

Salmonella paratyphi B and Salmonella typhimurium were starved in seawater microcosms respectively for 12 and 6 years. After starvation periods, major part of water was evaporated in each microcosm and salt crystals appeared. No culturable cells were obtained in selective and non-selective media. Salty suspension of each microcosm was inoculated in the yolk sacs of embryonated chicken eggs. Cul...

Molecular Detection of Salmonella Serovar Isolated from Eggs

Abstract Background and Objective: Salmonellosis is the most common type of food poisoning in developed and developing countries that is caused by Salmonella serotype. Hence, we aimed to identify the Salmonella serovars in eggs obtained from Kohgiluyeh and Boyerahmad province and to evaluate antibiotic resistance of the isolated strains. Material and Methods: In this study, 210 eggs were co...

Determination of enrofloxacin residue in chicken eggs using FPT and ELISA methods

Comparative Evaluation of Some Properties of Chicken and Japanese Quail Eggs Subjected to Different Storage Methods

This study investigated the potential effects of egg quality indices at 95% confidence level in order to minimize quality loss during different storage conditions. The chicken and quail eggs’ quality indices including weight, albumen index, yolk index, Haugh index in fresh eggs as well as after storing in moist sawdust, oil, and refrigerator were measured for six weeks. The results revealed tha...
