Define pathogen.

Expert Solution & Answer

Summary Introduction

To define: The term “pathogen.”

Introduction: Pathogens are the disease causing organisms that are able to invade the host immune system to establish a specific disease.

Explanation of Solution

Pathogen can be defined as anything that can cause diseases. The ability of a pathogen to cause a disease is known as pathogenicity and the process by which it occurs is called pathogenesis.

Most of the pathogens are microorganisms such as viruses, bacteria, fungi, and other parasites. Each of the pathogens has different life cycle and different strategies to invade host immunity.

Different types of pathogens are:

Bacteria: These are the prokaryotic unicellular organisms that possess varying degree of body shapes and size. Bacteria are the most common pathogens of the human. Examples of some diseases caused by the bacteria are; typhoid fever, tetanus, cholera, plague, pneumonia and so on.
Virus: These are the obligate intracellular parasite which cannot thrive outside the host organism. Examples of some diseases caused by the viruses are; AIDS, Hepatitis, common cold and so on.
Fungi: These are the eukaryotic organisms that are a major threat to human health some fungal diseases of human are: candidiasis, athelete’s foot and so on.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. 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?
