In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000
bacteria/gram is considered unsafe.
Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto
standard petri plates of nutrient agar. The following colony counts are measured:

It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?arrow_forward
