Most strains of E. coli are harmless and are part of the normal gut flora in humans and animals. However, some strains, particularly Enterohemorrhagic E. coli (EHEC), can cause serious foodborne illnesses, leading to symptoms like severe abdominal cramps and diarrhea. It's important to properly handle and cook food to avoid infections from harmful strains. Overall, while many E. coli strains are benign, caution is warranted with certain pathogenic varieties.

The relationship between humans and E. coli can vary depending on the strain. Most strains of E. coli are harmless and live in the intestines of healthy humans, aiding in digestion and nutrient absorption, which represents a mutualistic relationship. However, some pathogenic strains can cause foodborne illnesses and infections, leading to a harmful relationship. Overall, the nature of the relationship is context-dependent, ranging from beneficial to harmful.
Virulent refers to pathogens that are capable of causing disease and often have mechanisms that enhance their ability to infect and harm the host. In contrast, avirulent refers to pathogens that do not cause disease or are less capable of doing so, often due to a lack of harmful traits or factors that allow them to evade the host's immune response. Essentially, virulent strains are harmful, while avirulent strains are benign or less harmful.
The influenza virus is in a continuous state of mutation. Each year different strains become prominent. If the educated guesses of the disease control folks are accurate, they can produce a vaccine that will be aligned with the proteins on all of the most common strains for a given year. Occasionally they get it wrong and the vaccine is only effective against a fraction of the most common strains. Because the strains are different from year to year, the previous year's vaccination is not very likely to provide immunity for the currently most common strains.
High-yield strains of plants.
Microbes are useful for producing food (like cheese and yogurt), breaking down organic matter in nature, and assisting in digestion in our bodies. However, they can also be harmful by causing diseases, food spoilage, and contamination of surfaces.
the most harmful is carbon dioxide.
"More harmful" and "most harmful." We would not use the -er and -est suffixes on the -ful which is already a suffix.
more harmful, most harmful
There are over 200 different strains of viruses that can cause the common cold, with rhinoviruses being the most prevalent. Other viruses, such as adenoviruses, coronaviruses, and respiratory syncytial virus (RSV), also contribute to cold symptoms. The specific strains circulating can vary from season to season and region to region. Monitoring by health organizations helps track which strains are currently most common.
There are 89 different strains of anthrax. One of the most notable is the Ames strain, which is highly virulent. The Ames strain was the strain used in the 2001 attacks.
