Mode of Transmission of Diseases

by
Mode of Transmission of Diseases

Mode of Transmission of Diseases The traditional epidemiologic triad model holds that infectious diseases result from the interaction of agent, host, and environment. More specifically, transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host.  An infectious … Read more Mode of Transmission of Diseases

by
Shiga toxin-producing Escherichia coli (STEC)

Shiga toxin-producing Escherichia coli (STEC) The Shiga toxin-producing E. coli (STEC), is also alternatively referred to as verocytotoxin-producing E. coli (VTEC), and enterohemorrhagic E. coli (EHEC). All members of this group are defined by the presence of Shiga toxin 1 (Stx1) or 2 (Stx2). Some but not all EHEC strains are LEE positive and form … Read more Shiga toxin-producing Escherichia coli (STEC)

Membrane Lipids

by
Membrane Lipids

Membrane Lipids Biological membranes consist of a lipid bilayer to which proteins and carbohydrates may be associated or covalently linked. Membrane lipids are lipids involved in forming the structure of biological membranes – both the cell membrane and intracellular membranes – and in membrane function, namely compartmentalization of biological processes. Membrane lipids consist primarily of … Read more Membrane Lipids

Enterotoxigenic E. coli (ETEC)

Enterotoxigenic E. coli (ETEC) Enterotoxigenic E. coli (ETEC) is defined as containing the E. coli strains that elaborate at least one member of two defined groups of enterotoxins: heat-stable toxin (ST) and heat-stable toxin (LT). Enterotoxigenic Escherichia coli, or ETEC, is thus the name given to a group of E. coli that produces special toxins that stimulate the lining … Read more Enterotoxigenic E. coli (ETEC)

by
Epidemiologic Triad- Agent, Host, Environment

Epidemiologic Triad- Agent, Host, Environment The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or “germs” can lead to disease. However, the germ theory of disease has many limitations. For example, it is well-known, that not everyone exposed to tuberculosis develops tuberculosis. The same exposure, however, in an undernourished or otherwise susceptible … Read more Epidemiologic Triad- Agent, Host, Environment

New York City Agar

by
New York City Agar

Introduction NYC Agar Base medium was originally developed by Fauer, Weisburd and Wilson at the New York City Department of Health for selective isolation of pathogenic Neisseria species from clinical specimens. NYC medium, primarily designed for isolation of pathogenic Neisseria, also readily supports the growth of large-colony mycoplasmas and T-mycoplasmas (Ureaplasma). It is a transparent medium, … Read more New York City Agar
