ABSTRACT This lab will be a review of the work of Yamaguchi et al. in their work with observing the overall characteristics, necessities for growth, and more specifically the invasion patterns of Streptococcus pneumoniae in the presence of erythrocytes; one of the most common type of blood cell in human blood (1). INTRODUCTION Streptococcus pneumoniae is a gram-positive bacterium, meaning it lacks an outer membrane making it more susceptible to antibiotics, which is related to many infectious

Bugs, bugs, bugs! Bugs are everywhere in our environment. The potential for infection never ends! The spread of infection is dependent upon three key factors. Pathogenic organisms, those that cause infection, require a source or home where they thrive, a means of transmission, and a susceptible host to be successful. The source of an infecting organisms is classified as endogenous or exogenous. Endogenous infections are caused by microorganisms that naturally inhabit the human body. These organisms
