This the last episode of 2021. What is chromogenic agar? In this episode I go over chromogenic agar used to detect MRSA. I also talk about Mannitol salt agar and how it aids in the isolation of Staphylococcus aureus.
On this episode I go over how to identify Staphylococcus aureus from a standard set of agar plates. I also go over a test used to determine if this organism is an MRSA or not.
In this episode I talk about Staphylococcus aureus. This is one of the most common organisms seen in Clinical Microbiology and a very serious one. Tune in to find about more about this organism, including its pathogenicity and significance in health care settings. Questions? Feedback?

This episode is part two of a two-part episode. What are the limitations of the Vitek MS? In this episode I go over the limitations of the Vitek MS regarding identification of organisms. I also go over the pros and cons of having this system in the laboratory.
What is MALDI-TOF? How is it used in Clinical Microbiology?. This is the first part of a two part episode where I discuss MALDI-TOF, and its applications in Clinical Microbiology.
Instagram follower suggestion: After mentioning on a post that Pasteurella was my favorite, a follower suggested for me to make an episode about it. In this episode I talk about Pasteurella, and why do I like it.
In this episode I continue going over anaerobic bacteria. Is blood agar sufficient to recover anaerobes? Listen to this episode to learn about different media used for the recovery of anaerobic bacteria.
In this episode I continue going over anaerobes. Are all sources acceptable for anaerobic cultures? How do you achieve the anaerobic environment these organisms need to grow? Find out in this episode.
What is anaerobic bacteria? What is a facultative anaerobe? In this episode I introduce anaerobic bacteria and its relationship to oxygen and growth. Some species are mentioned.
Following up Dania's interview, in this episode I go over thioglycolate broth. What is it used for? Is it helpful in cultures? Listen to find out.
This week's episode features Let's Talk Micro's second interview. Dania Casellas is a microbiologist that performs testing on donor organs.
In this episode I continue going over tests and biochemicals for gram negative cocci. In addition I briefly go over different species of gram negative cocci and introduce new agar: Martin Lewis and Modified Thayer Martin.
In this episode I start going over tests and biochemicals for gram negative cocci. First up, the catarrhalis disk, used for the identification of Moraxella catarrhalis.
What is the urease test? What is the principle of it? Is it only used for gram negative rods? In this episode I go over the urea test, including its principle, reactions, and its differences and similarities to the TSI and LIA tests.
What is the lysine iron agar test? What is it used for? In this episode I go over this test including reactions and comparing and contrasting it with the TSI test.
What is TSI? Which organisms is it used for? In this episode I go over the Triple Sugar Iron test, including its components, how does it work and examples of organisms and their reactions.
In this episode I go over media that Karla Zamora mentioned in her interview such as Hektoen, XLD and Palcam. I discuss components of the agar, colonial morphology and more.
Let's Talk Micro's first interview features a conversation with Karla Zamora, an environmental microbiologist from Mexico. In this episode she talks about her work including techniques and organisms she works with.
In this episode I continue going over biochemicals for gram negative rods: oxidase. I also briefly discuss some species of gram negative rods and their oxidase results.
In this episode of Let's Talk Micro , we kick off biochemicals for Gram-negative rods with the indole test. After wrapping up the Gram-positive cocci last week, we now explore what indole is, how the test works, and how it helps differentiate organisms like E. coli , Proteus , and Klebsiella . A classic biochemical that still matters in today's microbiology lab. Check out the website: https://www.letstalkmicro.com/ Questions? Feedback?

In this episode of Let's Talk Micro , we continue exploring the tools that aid in the identification of gram-positive cocci. Tune in as we discuss the optochin disk, used to help identify Streptococcus pneumoniae , and the Microdase disk test, which supports the identification of Micrococcus species. These simple yet powerful tests remain essential in the clinical microbiology lab. Check out the website: https://www.letstalkmicro.com/ Questions? Feedback?
