If an individual was exposed to the highest dose of bacteria from the stream, which of the following bacteria would have the lowest probability of causing illness if ingested?
Answer:
When an individual is exposed to a high dose of bacteria from a stream, the bacteria’s pathogenicity and ability to cause illness upon ingestion become crucial factors. Among the following bacteria, Lactobacillus would have the lowest probability of causing illness if ingested.
Lactobacillus is a type of bacteria that is commonly found in yogurt and various fermented foods. It is known for its probiotic properties and beneficial effects on gut health. In general, Lactobacillus is considered safe for consumption and is even intentionally consumed for its positive effects on digestion and immunity. Therefore, compared to other pathogenic bacteria, Lactobacillus would have the lowest probability of causing illness when ingested in high doses.
