Summary Introduction

Introduction:

Robert Koch proposed postulates to classify a causative agent as a pathogen of a particular disease based on four important criteria. These came to be known as Koch’s postulates, which are given as follows:

  1. The pathogen must be present in all organisms with that disease.

  2. The pathogens must be able to grow on a culture plate.

  3. The organism must be able to cause a disease in a healthy organism.

  4. The organism isolated from the diseased organism must be identical to the conventional causative agent.

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: 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 16
9. Chicken combs in chickens is an example where you see interactions between genes. See potential genotypes and phenotypes below. Which genotype, when mated to a rose comb chicken, will produce progeny that are 50% walnut comb and 50% pea comb? walnut (RRPP) walnut (RrPP) pea (rrPP) walnut (RRPP) walnut (RrPp) pea (rrPp) rose rose single (RRPP) (Rrpp) (rrpp)
Describe a compound light microscope and its importance in microbiology (2) examples of at least two microbes viewed under a compound light microscope and their general characteristics (note: the microbes you choose do not need to be the ones outlined in the above tutorial video) and (3) at least one source you used for the information included in your infographic.
