Meet Cory

                                                               
                                                      Corynebacterium on blood agar



Hello STEM Family,

I’d like you to meet my friend Cory. Cory is long, dark, and radiates positivity. I know what you’re thinking, but currently Cory is cohabitating with S. Epidermis on Mt. St. Nares. They’ve been together for the last thirty days. However, if you want to  meet a special friend like Cory, here’s what to look for. They have to be comfortable swimming in shallow and deep water as there is little oxygen down there; have an insatiable sweet tooth, lactose tolerant, and a bubbly personality.

Corynebacterium and S. Epidermis were isolated from the nose of our participant with combination skin. Both are gram positive bacteria; however, Corynebacterium are rods and S. Epidermis are coccoid. Biochemical properties include: catalase positive, facultative anaerobic,  beta hemolysis positive, and glucose positive. Corynebacterium are typically lactose negative. However, we identified one of the two strains that are actually lactose positive.

New Semester...New Project

Every time I start a project, I always think that I'm going to kick that football right away. And then life happens, and I'm flat on my back. This semester I have decided to examine the inhibitory effects of lactic acid producing bacteria on two common food pathogens: E. coli and Salmonella. In my mind I had this laid out perfectly. In my gut, I knew this wouldn't be easy, but I think my enthusiasm kept me from seeing how difficult it would really be. Nevertheless, I will persevere. And by the end of the semester, I will have kicked that football.

Staphylococcus Aureus

                                                                                            Staphylococcus Aureus on Mannitol Plate S. Aureus was identified in two of the participants in my study. Although this organism is typically described as an opportunistic pathogen, it is a part of the normal skin flora of approximately 1/4 of the US population. S. Aureus is also associated with dry skin and atopic dermatitis (Williams et al, 2017). Consistent with current research, the person in our dry skin condition had the most colonies of S. Aureus when compared to the participants with normal and combination skin.  Biochemical characteristics of S. Aureus include, mannitol  +, coagulase +, glucose +, lactose (+) or (-) , and anaerobic.

Mathematics, Engineering and Science Achievement (MESA)

Just wanted to share some good news. My oldest daughter is a member of the MESA club at Vista del Sur Elementary School in Laveen. She is a part of the On-Site Engineering Design group. In this competition, the students show up at their destination and are given a task. They receive $500 in monopoly money to buy all the supplies they need to complete the project. At regionals, her group was required to build a shelter for an egg so that it wouldn't break when dropped. Her group's design got them second place and now they will be participating in the state competition at Apollo High School in April!!!  GO Tigers!!!!
