bacteria What is 99% of the biomass of the microbiome composed of? a biofilm What do bacteria often exist in? FALSE; it is 99% bacteria, but there are also: - viruses - fungi - protozoa - archaea **complex dynamic community in BOTH health and disease (~1000 microorganisms, 700 species of bacteria) TRUE or FALSE: The oral microbiome is composed only of bacteria. in disease, you get an increase in the diversity of the bacteria What visual observation can be made about the differenc...

Salmonella is a type of bacillus bacteria that causes diarrheal illness in humans. This bacterial species is a pathogen and has more than 2500 subspecies from both human and animal strains. Salmonella has many types, and each type causes specific health issues that include typhoid fever and gastroenteritis. Salmonella causes infection in humans, and the condition is known as Salmonellosis that mainly infects the intestinal tract. The most common way of infection is by consuming raw food and...

1. What is the difference between chemically defined and chemically complex media? Give either a clinical or environmental research example for which each media type would be the most appropriate choice for culturing microorganisms. The key difference between chemically defined and chemically complex media are their compositions. Chemically defined media is made up of all known compositions. While, chemically complex media is made up of unknown compositions (which can vary from batch to bat...
