“…The S. Enteritidis G1 Nal r strain used in this study is a phage type 4 strain and was chosen because it is invasive in cultured intestinal epithelial cells and virulent in orally inoculated chickens and mice (79,83). A spontaneous nalidixic-acid-resistant mutant of 22079 (G1 Nal r ) was derived according to the methods described previously (80,81). A collection of 12 Escherichia coli S17-pir isolatesGiven the large number of mutants screened in this study, it was not possible to optimize the CFU or optical density of the mutants prior to infection.…”

Transposon Mutagenesis of Salmonella enterica Serovar Enteritidis Identifies Genes That Contribute to Invasiveness in Human and Chicken Cells and Survival in Egg Albumen

Salmonella enterica serovar Enteritidis is an important food-borne pathogen, and chickens are a primary reservoir of human infection. While most knowledge about Salmonella pathogenesis is based on research conducted on Salmonella enterica serovar Typhimurium, S. Enteritidis is known to have pathobiology specific to chickens that impacts epidemiology in humans. Therefore, more information is needed about S. Enteritidis pathobiology in comparison to that of S. Typhimurium. We used transposon mutagenesis to identify S. Enteritidis virulence genes by assay of invasiveness in human intestinal epithelial (Caco-2) cells and chicken liver (LMH) cells and survival within chicken (HD-11) macrophages as a surrogate marker for virulence. A total of 4,330 transposon insertion mutants of an invasive G1 Nal r strain were screened using Caco-2 cells. This led to the identification of attenuating mutations in a total of 33 different loci, many of which include genes previously known to contribute to enteric infection (e.g., Salmonella pathogenicity island 1 [SPI-1], SPI-4, SPI-5, CS54, fliH, fljB, csgB, spvR, and rfbMN) in S. Enteritidis and other Salmonella serovars. Several genes or genomic islands that have not been reported previously (e.g., SPI-14, ksgA, SEN0034, SEN2278, and SEN3503) or that are absent in S. Typhimurium or in most other Salmonella serovars (e.g., pegD, SEN1152, SEN1393, and SEN1966) were also identified. Most mutants with reduced Caco-2 cell invasiveness also showed significantly reduced invasiveness in chicken liver cells and impaired survival in chicken macrophages and in egg albumen. Consequently, these genes may play an important role during infection of the chicken host and also contribute to successful egg contamination by S. Enteritidis.

“…Żeńszeń (Panax ginseng) zawiera substancje czynne o działaniu stymulującym aktywność fagocytarną makrofagów, aktywność komórek NK, produkcję cytokin przekaźnikowych oraz IgM i innych immunoglobulin, a także proliferację limfocytów T. W doświadczeniu na kurczętach rzeźnych zakażonych bakterią Salmonella gallinarum podawanie preparatu z żeńszenia w wodzie pitnej obniżało liczbę padnięć, stopień zainfekowania wątroby i liczbę ptaków, w odchodach których stwierdzano kultury badanej bakterii (43,47).…”

The aim of the study was to review the results of scientific research on the effect of herbs and phytogenic feed additives used in poultry nutrition on animal welfare, breeding conditions, and the quality of meat. The article explains the importance of feed additives used in poultry nutrition. It discusses the role of herbs and phytogenic feed additives in nutrition in the context of the increasing demand for and consumption of poultry meat. The article also analyzes the influence of herbs and phytogenic feed additives on animal welfare, rearing conditions, and meat quality. The results of research on the effect of herbs and phytogenic feed additives used in poultry nutrition are not unequivocal. In view of the high demand for poultry meat, there is need for continued research on the optimal composition of herbal mixtures in nutrition to obtain good breeding conditions and high quality meat.
