Document Summary
Microbes regularly found at an anatomical site. Symbionts that have various interactions with host. Continuous stream of mucous generated by ciliated epithelial cells to swallow microbes. Low microbial population due to low ph. Highest microbial population in host of dry weight fecal matter. Uterus may not be sterile during embryonic and fetal development. Newborns have a diversity of bacteria in stool. When premature rupturing of membranes exposed infant to infection antibiotics are sometimes given to mother who do not deliver within. Lactobacillus provides a benefit to newborns delivered vaginally, as it better strengthens their colon sooner. C-sections will achieve this, but it will take longer. Human milk contains 600 species of bacteria and also sugars indigestible by infant. Suggesting that lactobacillus provides enzymes required to digest milks. Mixed population of coliforms, lactobacilli, enteric streptococci and staphylococci. When normal microbiota grow outside is niche. Causes and consequences of colonization and growth by microbes normally absent at a specific body site.
