0314 Biofilms in Chronic Wounds: Current Research and Future Direction ABSTRACT Chronic wounds continue to be a significant healthcare problem. Although myriad factors have been implicated in impaired wound healing‚ recent research has focused on the role of matrix-based bacterial communities called biofilms that are often associated with chronic wounds. Various in vitro and in vivo models have been developed to study the role of biofilms in non-healing wounds. Basic science and clinical

INTRODUCTION Both scarring and nonscarring alopecias have been described with long-term use of epidermal growth factor receptor (EGFR) inhibitors. Current treatments revolve around anti-inflammatory agents such as topical corticosteroid ointments‚ creams‚ and intralesional injections to reduce follicular inflammation. Unfortunately‚ none of these therapies are universally effective. Here‚ we describe a case of erlotinib-induced alopecia refractory to intralesional and topical corticosteroids that

Streptococcus spp. After the initial tests were conducted‚ five more tests were done to narrow down the genera and species. From the provided list of possible unknown genera‚ the only genus left was Staphylococcus. However Staphylococcus has many species‚ so test focused on differentiating the many species of Staphylococcus were conducted. First‚ to confirm that the unknown wasn’t a Micrococcus sp.‚ the bacitracin test was used. This test confirmed that the unknown 32 was a resistant bacitracin resistant bacterium

In the United States of America‚ we are very fortunate to have access to quality medical facilities. Employees in the medical profession have chosen to dedicate their lives to help support and maintain the lives of others. In order to achieve these goals to the fullest‚ patients in the hospital should be provided with the best possible care. Unfortunately‚ despite their dedication and efforts to provide good medical care‚ there are several patients that contract infections from the hospital.

CATALASE Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in reproductive reactions. Likewise‚ catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of molecules of hydrogen peroxide to water and oxygen each second. Catalase is a tetramer of four polypeptide chains‚ each over 500 amino acids long. It contains

This lab was conducted in order to understand basic differences among differential and selective media‚ while recognizing how each media is used to isolate and identify microorganisms (Wistreich‚ 2003). The first microorganism analyzed was Staphylococcus epidermidis. This organism is gram-positive‚ single celled‚ arranged in grape-like clusters‚ and cocci in shape (Bukhari‚ 2004). S. epidermidis is approximately 0.5 to 1.5 micrometers in diameter‚ it is a facultative anaerobe but grows best
