Found in Nachos
In late April of this year, there was an outbreak of botulism due to contaminated nacho cheese at a gas station outside of Sacramento, California. The issue is no longer a threat, as the lot of cheese has been recalled and was discarded on May 5, 2017. However, the outbreak took its toll on nine people which were hospitalized, and one person died. Incidents such as these remind us of the importance of proper food preparation and preservation.
Seemingly innocent gas station food proved to be deadly in Sacramento.
Botulism is caused by the bacteria Clostridium botulinum. This Gram-positive organism has caused documented cases of illness dating back to the 18th century. When we think of preserved foods, we usually think they are safe. After all, isn’t that what preserved means? However, low oxygen conditions can promote germination of this spore-forming anaerobic organism.  Improperly processed canned and jarred foods are some of the most common culprits. However, as we see with the nacho cheese case, this can be found in any container that lacks oxygen.
Another cause for infection from botulism is from wounds, often relating to intravenous drug use.
Of all the documented cases, the most common occurrence of botulism is actually in infants. Infants who ingest the spores become colonized in the gut. Honey has been linked to a majority of these cases, and therefore, it is advised that honey not be fed to children less than 1 year of age.
Although botulism infections usually last one to ten days, some cases can become more severe. The man who died in the nacho cheese incident was in the hospital for several weeks on a ventilator before his eventual passing. While the disease is fatal in about three to five percent of cases, it can usually be treated with an equine-derived antitoxin. However, complications from using this antitoxin can arise, such as serum sickness and anaphylaxis. Therefore, it is not recommended for use with infants. Since infants are the most affected age group for disease, in 2003, a human-derived antitoxin was developed, giving a new treatment option for infants who have the misfortune of contracting this disease.
Contrary to popular belief, Clostridium botulinum itself is not actually what causes the illness; rather, it is the Botulinum neurotoxin it produces, which is the most lethal toxin known. The toxin, which is released upon sporulation, causes blurred vision, drooping eyelids, slurred speech, and even paralysis. Botulism toxin exists in seven different serological forms, which are labeled with the letters A-H. Types A, B, and F can be proteolytic, making detection easier since they give off a rotten odor. All serotypes affect humans, except C and D, which only affect animals. In the United States, virtually all reported cases have been due to types A and B.

Prevention of bacterial growth and its associated spores is not difficult. Though the nacho cheese travesty made headlines, cases usually arise from home-preserved foods. Hopefully, anyone that is practicing this hobby knows of the dangers associated with canning and jarring foods and usually understands the proper precautions that need to be taken. For people new to food preservation, the USDA and CDC lists some important instructions in home canning, including taking special care for foods that have low acid (pH > 4.6). Never eat from a can that is bulging or leaking. Never eat food that is foamy or smells bad. When in doubt, throw it out!
Being a fairly rare disease, the case in Sacramento was shocking to say the least. In 2015, there were 39 botulism cases linked to food. The largest outbreak was due to potato salad at a potluck where 27 people became ill. As we are coming up on summer, special precautions are needed to defeat this potentially devastating food-borne disease

Advances in 
Gram positive antimicrobials
New Superdrug
Beats Superbugs
A new and very potent weapon against VRE and VRSA has been developed that is at least 1,000 more active than vancomycin and leaves no chance for the development of resistance!
Antibiotic resistance has been extensively explored and has been a conundrum for the medical profession for several decades as bacteria find ways to break down and inactivate the most sophisticated compounds, while others go so far as to alter their metabolic pathways in order to circumvent antimicrobial targets.


While vancomycin has been a staple therapy since 1958 in the fight against Gram-positives such as Staphylococcus, resistance in enterococci is quite common. Enterococcus faecalis produces low-affinity penicillin binding protein (PBP), which makes it more difficult for penicillin to bind to this bacterium.  Other species of enterococci produce inactivating enzymes against aminoglycoside antibiotics, like streptomycin or gentamicin.  Vancomycin resistant Enterococci (VRE) express multiple phenotypes, specifically gene clusters of VanA, VanB, VanC, VanD, VanE, and VanG, that alter an amino acid sequence and prevent binding of vancomycin.


Traditionally, vancomycin inhibits synthesis of the peptidoglycan cell wall by binding to amino acid residues of specific peptides within Gram-positive bacteria; however, some species of enterococci are able to bypass this mechanism by altering this amino acid sequence using lactate (VanA, VanB, and VanD gene clusters) or serine (VanC, VanE, and VanG gene clusters) instead of the typical alanine.  The frightening aspect of this mechanism is the ability of these strains to transfer these resistance genes to other bacteria (even those from a different genus and species) via horizontal gene transfer.


This means bacterial genera normally inhibited by vancomycin could obtain resistance to it, potentially becoming multi-drug resistant if they already carry other resistance genes.


In a recent breakthrough study at The Scripps Research Institute, scientists have altered vancomycin in such a way to increase its antimicrobial potency.  In April, 2017, Dale Boger, PhD and his team were able to change the structure of this drug, nicknamed “Vancomycin 3.0,”  by adding two compounds to its periphery. This represents the first time that three different mechanisms of action were combined into one drug. This resulting “superdrug”  has a potency of 1,000 times that of its predecessor!
Dale Boger (right) and Akinori Okano (left) leading the  fight against resistant Gram positive bacteria at the Scripps Research Institute in San Diego, California.
Their modified vancomycin is the first antibiotic equipped with three different mechanisms of action, making it nearly impossible for bacteria to acquire resistance against the modified form.  A bacterium resistant to traditional vancomycin would have to overcome two additional mechanisms of action.  “This increases the durability of this antibiotic. Organisms just can’t simultaneously work to find a way around three independent mechanisms of action.  Even if they found a solution to one of those, the organisms would still be killed by the other two,” Dr. Boger explained.  In the lab, the modified vancomycin was able to inhibit both resistant and non-resistant strains of enterococci.


Vancomycin 3.0 has a complicated structure that combines three mechanisms of action (highlighted in green) against Gram positives.



The drug is not quite ready for clinical trials, since Boger’s team is attempting to find ways to reduce the expensive 30 steps required for its fabrication. To reach the market, it may take up to five years.
Antibiotic modification may be the beginning of a new fight against bacterial resistance.  If Dr. Boger’s team is able to perfect this modification process, who’s to say that it can’t be done with other antibiotics as well?


We may now have the tools to fight the dreaded “superbug,” and it shows thinking outside of the box may be a new and creative way to exploit available drugs that may be potentially improved.

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.”
