The ratio of TUNEL-labeled surface over the entire surface area of the egg was then measured (Pannebakker et al., 2007). The research article results shows that A. tabida, has become dependent on W. pipientis to reproduce. W. pipientis affects the wasps oogenesis, but the specific mechanism responsible is yet unknown. Pannebakker et al. (2007) research shows the W. pipientis influences programmed cell death processes in A. tabida by making its presence essential for the wasps eggs to fully mature. In conclusion, this study suggests the bacterium’s strategy causes the host to be dependent through evolution, thus creating a quick transitioning phase from commensalism (parasitism) to mutualism, where both organisms benefit.

infantisis. A breeding scheme was set up with polymeric Ig receptor-sufficient and deficient mice to understand the effects of breast milk-derived SIgA on development of the host’s immunity and gut microbiota, thus evaluating the relationship. The mice that had a Pigr gene mutation were used. Tissue histology and immunofluorescence microscopy were performed on the mouse’s tissue. Quantification of Fecal IgA and for Bacteria in MLNs was performed. After quantification, the mouse’s fecal microbiota was analyzed by PhyloChip hybridization at the early days of the mouse’s life. Once the mice reached the age of 8-10 weeks, each mouse was induced with colitis. Epithelial cells were dissected from the mouse’s colon and isolated. After the cells were isolated the gene expression was analyzed. After the analysis, genes regulated by SIgA were identified. Lastly, a statistical analysis was performed to see the differences in IgA concentrations, colony forming unit, and gene expression (Rogier et al., 2014). When a baby is first born, its immune system is naked; it will receive its first source of antigen-specific immune protection by receiving its first serving of breast milk. The breast milk appears in a form of secretory IgA also known as SIgA. Mice that were breast feed compared to those who were not contain a significantly different gut microbiota when they approach adulthood. When exposed to SIgA at an early age, a pattern of intestinal epithelial cell gene expression.
