Asexual and Sexual Reproduction
Some living things reproduce by cloning; producing offspring that are genetically identical to the parent. Organisms that procreate sexually create genetic novelty.

Bacterial Cell Wall Structure
The amount and location of peptidoglycan in the prokaryotic cell wall is what determines whether a bacterium is Gram-positive or Gram-negative.

Cells & Viral Pathogenic Microbes
All living things are composed of one or more cells. Unlike cells, viruses, viroids and prions are acellular, nonliving parasites that require a living host to reproduce.

Cells, Viruses, Viroids & Prions
Infectious disease can result of cellular organisms, such as bacteria (prokaryotes), from eukaryotes (cells like ours) or from nonliving infectious agents.

Gram Negative ( Gram- ) Bacteria
Most bacteria have one of these two types of cell walls. The differential Gram stain uses two dyes to distinguish between bacteria based on cell wall structure.

Gram Negative Bacterial Stain
Gram- bacteria stain pink due to the location of cell wall peptidoglycan and an external LPS membrane. Here's how Gram staining identifies Gram negative organisms.

Gram Positive ( Gram+ ) Bacteria
Most bacteria have one of these two types of cell walls. The differential Gram stain uses two dyes to distinguish between bacteria based on cell wall structure.

MOA of Macrolide Antibiotics
Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do they destroy bacteria without hurting our cells?

Prokaryotic and Eukaryotic Cells
There are only two basic types of cells, primitive prokaryotes and the more complex eukaryotes. Here are the main features that distinguish these cell types.

Prokaryotic Microbe Cell Biology
Prokaryotes are evolutionarily ancient, for billions of years the only form of life. Here's a summary of the basic "parts & pieces" of these primitive cells.
