Infection biology: Gut microbe helps thwart Salmonella Date: April 19, 2019 Source: Ludwig-Maximilians-Universität München Summary: Researchers have identified a bacterial species in the gut microbiome of the mouse which protects against infection by human-pathogenic Salmonella. Share:         FULL story Written by  vinod kumar kushwaha  Msc in microbiology on aug 2018 Salmonella enterica is the name of a group of rod-shaped bacteria that can cause gastroenteritis in humans and other animals. Salmonella infections can have serious consequences for certain high-risk groups, such as babies, young children, the elderly and individuals whose immune systems are functionally compromised. Most people with a normal complement of gut microflora (microbiota) generally have little difficulty coping with such infections. Only in 10-20% of cases in which the pathogens are ingested -- usually via contaminated food products -- does an infection actually result. But the

In general, indicators are most often used to assess food sanitation, and most of this chapter treats them in this context; however, quality indicators may be used, and some general aspects of this usage are outlined in the following section. 2.     INDICATORS OF PRODUCT QUALITY Microbial product quality or shelf-life indicators are organisms and/or their metabolic products whose presence in given foods at certain levels may be used to assess existing quality or, better, to predict product shelf life. When used in this way, the indicator organisms should meet the following criteria: • They should be present and detectable in all foods whose quality (or lack thereof) is to be assesse
