The Cloud Grows – Say hello to the MAGI…

Having trouble pinning an unknown to a point on the GNNFB-Enterics-Vibrio spectrum? Allow me to introduce you to the SAVE MAGI.

This program uses a trio of 18-test matrices to point users to one of the individual WIPs for the likeliest final identification. Just enter the results of the 18 tests and Melchior, Balthazar, and Caspar will put their heads together to compute what they feel is the best option. Click the SAVE Magi option in the AID Cloud menu bar to try it out.

AID Cloud Report

In the week since the AID Cloud was announced, pschreck.com has received over 2000 hits from at least a dozen countries. The WIPs have been accessed at least 1200 times in that time frame as well. I hope these tools continue to assist the medical community.

App Identification (AID) Cloud

Dear Microbiology Friends,

In the past week, pschreck.com has introduced the ASHEX WIP – an online tool that helps identify gram-negative, non-fermenting bacilli (GNNFB). Over the course of the last few days, with the help of Brent Barrett, Enterobacteria and Vibrio species WIPs have been developed. Together, with the ASHEX WIP, these programs mark the start of the AID Cloud. The Aid Cloud is a set of online identification applications meant to help end-users (such as laboratory specialists) ID clinical isolates.

You’ll notice that beneath the main toolbar of the pschreck webpage, there is a secondary gray banner that begins with AID Cloud on the far left. That link will take you to a better description of the AID Cloud. To the right, various WIP links have been added that will take you to specific identification tools. (e.g. the Vibrio WIP link will take you to an identification tool that separates Vibrio species.)

These matrices do not communicate with one another, so users do have to have a general idea as to which WIP they want to use. In other words, the Enterics WIP will not contain information from the ASHEX WIP and vice versa. Feel free to contact Adam with any questions. I hope you all find use for these tools in your labs.

WIP Announced

Paraphrased from my dad’s email to CLINMICRONET:

Dear Colleagues,

I want to inform you of a new tool for identification of glucose non-fermenting gram-negative bacilli that is available as freeware at www.pschreck.com. This is a computer assisted probability program created by my son Adam, that is linked to the non-fermenter database that I have developed with isolates collected over the past 20 years. The database consists of human clinical isolates and includes rare and unusual isolates from the CDC non-fermenter collection kindly furnished by Maryam Daneshvar and Dannie Hollis. The database includes 45 phenotypic characteristics to 815 individual isolates representing 88 separate species and groups of NFBs. The program allows you to enter as many phenotypic characteristics that are available and calculates likelihood probability, modal score, and provides phenotypic tests that will separate top three taxa when likelihood score is less than 95%. To access, click the WIP tab in the tool bar and enter your reactions on the worksheet. The WIP is a web application that works on any PC, Apple, or smartphone system with an active internet connection. It requires no downloads and will run within your internet browser.

If you would like to access the entire database with all phenotypic reactions click Non-Fermenter ID Tab in the tool bar, then click ASHEX 12X EXCEL File in Step 3. Click read only to open the excel file. If you have any difficulties, you can contact Adam.

We hope you all enjoy this new tool. Thus far, the responses seem to be overwhelmingly positive.

~Adam

ASHEX WIP Updates

The WIP has been updated to now list modal scores as well. In addition, if the Modal Score falls below the 1.0 threshold, it will display the anomalous results of the top candidate specimen.

ASHEX Web ID Program

For those who have trouble downloading programs or have systems incompatible with PIBWin, I have designed a web-based application that will compute ID probabilities without the need to download anything. Click the ‘WIP’ link at the top of the page to access the new ASHEX WIP!

ASHEX12X released on January 9, 2012

Hello pschreck.com followers! I am pleased to announce the release of the ASHEX12X matrix. The current version represents 815 clinical isolates of gram-negative, glucose non-fermenting strains. The matrix has the ability to identify 88 organisms. 30 of these have met the 10 isolate criterion established in 2004, and an additional 30 are represented by at least 5 isolates.

Thank you for your patience. I hope you enjoy the update,
A.P. Schreckenberger

Welcome to PSCHRECK.com

Welcome to Dr. Paul Schreckenberger’s Clinical Microbiology webpage and the home of the ASHEX Glucose Non-Fermenting Bacteria ID Database. This site was founded in 2004 to provide a home for our project, the ASHEX matrix, which utilizes a program called PIBWin to identify glucose non-fermenting bacteria with a set array of phenotypic tests.

Enjoy your stay,
A.P. Schreckenberger
