“Stool Pigeon”
The original Stool Pigeons were real pigeons that were perched on a stool. Pigeon hunters long ago would tie down a pigeon to a stool. It would then flap its wings and attract other pigeons that would get caught in the hunter’s net. Thus, Stool Pigeon became known as a term for an informer or decoy.

Harold: It could be due to the the cold weather we are having.

Maude: I don’t think so. My dashboard is giving me some kind of odd warning.

Harold: What is it telling you?

Maude: I’m not sure; it’s just an image of a man sitting on a toilet! What could that mean?

More exciting discoveries coming soon!


iChip and the 99%



A new device called the iChip, short for isolation chip, may unlock the potential to culture the majority of microbes that still remain undiscovered. 


So far, standard microbiology culture methods have only been able to grow about 1% of microbial species in vitro on synthetic media (1). Beginning in 2002, the iChip was designed and tested by a team of researchers from multiple universities and industry partners and eventually completed its phase I (proof of concept) design in 2010. 
The iChip is capable of isolating and growing pure microbial cultures at a high throughput. With the ability to recover more organisms that were previously unable to be cultured by current methods, the iChip has the potential to improve the present understanding of environmental microorganisms and will allow for new discoveries that are applicable to various areas of biotechnology and medicine (2).


What makes the iChip unique is that it allows for bacteria to remain in their “natural environment” by bringing the environment to the lab. The iChip is capable of culturing organisms from soil, sea water, saliva, salt marsh, and wastewater bioreactors (1,2,3).


In order to accomplish this, the iChip utilizes a “chip,” which consists of a hard piece of plastic with 192 tiny wells.  To use this device, the user simply dips the unit in a bacterial sample mixed with agar  to trap a single cell in each well.  After collection of the bacterial sample, a diffusion membrane is placed on each side of the chip in order to lock the microbes in place. The membranes are subsequently secured with plastic plates, and the iChip is placed into a large sample of its original environment where nutrients may permeate through the membranes. This has been shown to allow for an observed 30,000% increase in bacterial growth compared to standard agar plates (1).

Thanks to the iChip, the team has analyzed over 10,000 microbial species in a simple one-step process. As a result, the team discovered 25 new antibiotics in 2005. The antibiotic with the most promise was isolated from a recently discovered organism called Eleftheria terrae. The new antibacterial molecule, named teixobactin, was successful in wiping out highly drug-resistant microbes responsible for anthrax and tuberculosis (4,5). Teixobactin has been observed to protect mice from bacteria that are non-susceptible to several different drugs, including methicillin-resistant Staphylococcus aureus (MRSA) (4).


This new antibiotic is already being chemically synthesized in two simplified versions using methods that may be reproduced on a commercial scale at the University of Lincoln, UK, for an economical and commercially available product for use in human clinical trials (4). Researchers believe that antimicrobial resistance is less likely to arise against these new synthetic antibiotics because the enzyme that the drug targets would require significant structure changes to become resistant (4,5).


With the ability to culture microbes quickly, testing the iChip in other environments may help identify additional molecules or proteins from unidentified organisms that may have medical or industrial value.
This new technology provides the possibility to recover microbes from difficult to reach and complex environments (e.g., outer space, deep ocean trenches, etc.). Advances in the iChip leave developers with high aspirations; the potential for expansion of new beneficial molecules is imminent. Standard culture methods that utilize agar or broth media often produces little to no growth, due to the lack of nutrients or growth promotion factors yet to be discovered.


The majority of molecules discovered thus far come from the 1% of bacteria known to exist. Now, the potential to tap into the remaining 99% is exciting for all avenues of scientific research.

Trio Bas
Air Samplers
Two heads are better than one!
Now with Bluetooth capability!
Trio Bas from Orum International has a robust impact air sampler for every type of use. Single, double, or triple heads are available from Hardy Diagnostics.
Testimonial from a Pharmaceutical Lab worker…
The two heads of TRIO BAS DUO air sampler was one of the best investments during the last two years. The laboratory staff responsible of the bacteriological sampling is able to double the number of environmental microbial cycles per day. This means more efficiency and lower cost, together with the  possibility to increase in the future the number of sampling in other areas of the premises.”

Fluoroquinolone Resistance
Screening Methods
Fluoroquinolones have been the staple of antimicrobial therapy since the launch of the flagship representative “Ciprofloxacin” by Bayer in the early 1980s.
Fluoroquinolones have a fluorine atom attached to the core quinolone molecular ring and this modification results in a class of broad-spectrum bactericidal agents that show increased stability and potency against both Gram negative and Gram positive organisms.
In the years since its introduction, many other fluoroquinolones have been cleared for use, such as gemifloxacin, levofloxacin, moxifloxacin, and ofloxacin, among others. As predicted, resistance to fluoroquinolones has increased in the last decade, as the majority of fluoroquinolones were introduced in the late 1990s. For instance, in large surveillance programs like SENTRY, data from 2013 to 2016 show the resistance rates at 15.6% and 18.6% for general Enterobacteriaceae and
Pseudomonas populations, respectively. However, the resistance rates are significantly higher in multi-drug resistant subsets (ref. 1). In the May 2016 edition of
Antimicrobial Agents and Chemotherapy publication by Bidell et al., the rate of resistance in Escherichia coli strains from hospital-associated urinary tract infections range from 25% to 43% (ref. 2). These recent data certainly support the importance of screening for non-susceptible isolates in patients prior to administering the drug for treatment.
Generally, resistance to fluoroquinolones occurs through step-wise mutations, which are a series of point mutations that occur over time in the gyrase or topoisomerase gene that alter the bacterial enzyme structure to make the fluoroquinolone less effective or ineffective at binding and disabling the enzyme. When a new fluoroquinolone is administered, it may be effective at killing the bacteria at first. However, point mutations that lead to a beneficial change in enzyme structure are selected for which facilitates resistance against the new drug. Each new fluoroquinolone presents a new selective pressure that a previous fluoroquinolone may not have presented. However, mutations can accumulate one at a time or in a step-wise manner, leading to increasing fluoroquinolone resistance with each successful mutation (ref. 3).
Fluoroquinolones are widely administered for urinary tract infections, pre- and post-prostate biopsy, and hospital or community acquired infections that show multi-drug resistance. However, the use of fluoroquinolones has been cautioned against as there have been cases linked to devastating side effects that involve the central nervous system and tendon rupture (especially the Achilles tendon).
When other treatment options are available, they should be followed before treating with fluoroquinolones, as this class of antibiotics has been observed to have a risk of debilitating side effects, even during a short treatment period. Therefore, the FDA has warned against using fluoroquinolones for sinusitis, bronchitis, and uncomplicated urinary tract infections. (ref. 4).
The practice of screening for fluoroquinolone resistant E. coli prior to transrectal prostate biopsy procedures to ensure the success of fluoroquinolone prophylaxis and to reduce the risk of infection was described by Dr. Liss in the Journal of Clinical Microbiology in 2011.
In essence, the procedure calls for inoculation of stool or rectal specimen into a selective pre-enrichment broth or plated media that contains a fluoroquinolone at the non-susceptible breakpoint, resulting in the triage of cases that may potentially involve fluoroquinolone non-susceptible isolates (ref. 5). The resistance phenotype is subsequently confirmed via conventional susceptibility methods (ref. 6).
While the resistance tide is constantly against us from all angles involving all types of resistance (ESBL, KPC, MRSA, VRE, Polymyxin resistance), increased awareness of risks associated with infection complications from ciprofloxacin resistant E. coli can certainly be decreased with a simple  screening for resistance.
