Wisdom to Ponder…
Alexander Hamilton
1757 ~ 1804
As one of the founding fathers of the United States, he was the first Secretary of the Treasury, founder of the national bank, and a promoter of a strong federal government. Tragically, he died at 47 after a pistol duel with Aaron Burr, leaving behind eight children.
“It’s not tyranny we desire; it’s a just, limited, federal government.”

“There is a certain enthusiasm in liberty that makes human nature rise above itself, in acts of bravery and heroism.”

“I never expect to see a perfect work from an imperfect man.”
“Nobody expects to trust his body overmuch after the age of fifty.”
“Our great error is that we suppose mankind to be more honest than they are.”
“People sometimes attribute my success to my genius; all the genius I know anything about is hard work.”
“When a government betrays the people by amassing too much power and becoming tyrannical, the people have no choice but to exercise their original right of self-defense – to fight the government.”
“Give all the power to the many, they will oppress the few. Give all the power to the few, they will oppress the many.”

G. vag and UTIs
Does Gardnerella vaginalis 
play an important role 
in Urinary Tract Infections?
A vaginal epithelial cell infected with multiple Gram negative and positive bacterial species including G. vaginalis, indicative of Bacterial Vaginosis (BV).

Urinary tract infections are a result of bacteria entering the urinary tract through the urethra. When these bacteria arrive at the bladder, they begin to multiply, leading to an infection. In most cases, the urinary system can usually fight off these invaders; but in cases where the defense of the urinary system fails, UTIs affect the bladder and urethra. 

When the infection persists in the bladder, it is typically caused by Escherichia coli. This particular type of infection is referred to as “cystitis.” In cases where the infection is found in the urethra, a result of gastrointestinal (GI) bacteria spreading from the anus to the urethra, this particular type of infection is called “urethritis.”

While E.coli has historically been the primary culprit of UTIs, studies show that the vaginal bacterium, Gardnerella vaginalis, plays a significant role. G. vaginalis is a gram-variable, facultative anaerobic bacterium that is non-motile and non-sporeforming.  It is commonly associated with bacterial vaginosis (BV) when it persists in the vagina and overwhelms the healthy Lactobacillus population, especially in young, sexually active females. It is now accepted that Gardnerella vaginalis is not the sole cause of the condition, which is characterized by a reduction in the numbers of Lactobacilli and an increase in other bacteria including: Gardnerella vaginalis, Bacteroides spp, Mobiluncus spp,  anaerobic Streptococci, Mycoplasma hominis and Ureaplasma urealyticum. The term Bacterial Vaginosis better reflects the diverse vaginal microbiology of this dysbiotic condition. On a gram stain, a vaginal smear generally shows a shift from Gram positive to predominantly Gram negative bacteria.

Recent studies show that G. vaginalis aids E. coli in its infection of the bladder. Researchers at the Washington University School of Medicine in St. Louis infected bladders of female mice with E. coli to initiate UTIs. When these mice recovered from the infection after one month, their urine was screened for E. coli, but none were detected. This screening was performed because former studies had shown that some E. coli persist in the bladder even post-infection and are found in very low levels in urine. After the infection had cleared and no E. coli was detected in the urine, researchers introduced either Lactobacillus crispatus or G. vaginalis, both residents of normal vaginal microflora, to the bladders of the mice. These bacteria were eliminated from the bladder within 12 hours of introduction. Interestingly, however, E. coli appeared in the urine of more than half of the female mice that were introduced to G. vaginalis.

With further speculation, it appears that G. vaginalis plays a role in the recurrence or “awakening” of E. coli in the bladder and, thereby, aids in recurrent infections. One quarter of women treated for UTI will experience a recurrence within six months.

It was found that some of the mice exposed to G. vaginalis had infections that moved from the bladder, up through the urinary tract, and into the kidneys, causing a kidney infection. Researchers at the university suggest that G. vaginalis may damage cells on the surface of the bladder, releasing the dormant E. coli housed in those bladders cells. As a result, when the dormant E. coli cells are liberated, they can begin to multiply and contribute to recurrent UTIs.

There are some major implications of this study which impact the diagnosis and treatment of UTIs. Of concern is the fact that the antibiotics commonly used to treat UTIs are not effective in eliminating G. vaginalis. 

Moving forward, it may be important for physicians and practitioners to consider a patient’s history of bacterial vaginosis and the presence of G. vaginalis in a UTI sample. Historically, G. vaginalis in a UTI sample may have been disregarded as a contaminant of the normal vaginal microflora. However, this study suggests that G. vaginalis may play a significant role in recurrent UTIs.

Do Bacteria Behave 
Differently in Outer Space?

Much work is needed to determine the characteristics of bacteria growing in a weightless atmosphere. There is growing concern about enhanced bacterial growth and resistance in outer space. 
Consider the following…
1. NASA discovered in the 1960s that E. coli and Salmonella grow twice as fast when orbiting in the space module.

2. Soviet scientists in the 1970s found that bacteria developed increased resistance to five antibiotics while in orbit. 

3. Cosmonauts on the Soviet space station Mir, which was operational from 1986 to 2001, endured conjunctivitis, food poisoning, and acute respiratory illnesses.

4. In 2006, Cheyl Nickerson from Arizona State University found that bacteria became more lethal to lab animals in space than on Earth.

5. During NASA’s space shuttle program, from 1981 to 2011, 29 astronauts officially reported severe head colds, fevers, stomach ailments, or other nagging infections while in orbit; none of them were life-threatening. Among all shuttle crew members, 75% took medications for minor ailments during their space flights.

6. A study at the University of Colorado last year compared E. coli bacteria on the space station with those on Earth. Their results show cells grew 13 times faster in orbit and that dozens of E. coli genes were more active in space than on Earth.

The cramped interior within the International Space Station creates a concern, especially when astronauts experience an altered microbiome after extended periods of time in space.

C diff Banana Broth
With nearly 500,000
C diff infections annually…

Will your infection control 
protocols hold up? 

Hardy announces a new medium for the detection of
Clostridium difficile bacteria and spores. This new medium is capable of saving hospitals many thousands of dollars. It is useful in monitoring the efficacy of cleaning procedures used in patient rooms. 

This is the first and only culture medium designed for the detection of C. difficile and its spores on surfaces in a hospital setting.  The specificity was found to be 100% in a recent study (see reference below). No special equipment or anaerobic supplies are needed! Obtain results in as little as 24 hours!

The ciliates are a group of protozoans characterized by the presence of hair-like organelles called cilia. Ciliates are an important group of protists, common almost everywhere there is water – in lakes, ponds, oceans, rivers, and soils. About 3,500 species have been described, and the potential number of total species is estimated at 30,000.

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.”
