Summary Introduction

To determine: The process of infectious disease.

Introduction. A reservoir can be defined as the natural environmental habitat where a pathogen is typically found. This site serves as the place from where the pathogen can cause direct infection. In such cases, the reservoir acts as the source of the disease. These reservoirs can be living or non-living, they can also be present in dead and decaying.

Explanation of Solution

Pathogen transmission and infection take place through a series of steps. The steps begin from the entry of the infectious organsim inside the host and then release into the environment. The steps by which the viral infection is established are as follows:

  • Entry of the pathogen into the host:. The pathogen can enter from the surrounding, contaminated material (fomites) or an infected host.
  • Attachment to the host cell: The structures like flagella, cilia, glycocalyx present on the pathogens help them to attach to the surface of the host cell.
  • Multiplication of pathogens and release in the host cell: The infectious particle multiplies inside the host cell, and the progeny are released into the body to spread the infection.
  • The release of the infectious particles into the surrounding: The pathogens after causing infection leaves the host body and returns to the environment to complete its life cycle.

Use the Henderson-Hasselbalch equation for a propanoic acid solution (CH₂CH₂CO₂H, pK₁ = 4.874) to calculate the quotient [A-]/[HA] at three different pH values. pH = 4.479 [A-] [HA] [A-] pH = 4.874 [HA] = pH = 5.220 [A-] = [HA]
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
