The reason for not using tuberculin skin testing to determine the TB status of an HIV+ person
Introduction:
Tuberculosis is the disease that causes infection in the lungs. It is caused by Mycobacterium tuberculosis. HIV is a human immunodeficiency virus which causes a very serious disease called AIDS (acquired immunodeficiency syndrome). HIV interferes with the immune system of the body and reduces the ability to fight infections. It kills the T- helper cells and makes the individual vulnerable to infections.

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: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward
