Fungal Meningitis - Steroids (Updates)

A recent meningitis outbreak has killed 30 people and sickened over 400. The involved fungus, typically has not been associated with such outbreaks. There is a reason, continue reading.

The fungus of topic is Exserohilum rostratum. The fungus is typically found eating plant matter in nature. As we know, mold is very opportunistic and will pretty much flourish anywhere in the right conditions.

Exserohilum rostratum has been identified in lab samples from 52 of those affected and was similarly found growing in unopened vials of steroids. These steroids seem to be the cause of the outbreak.

Exserohilum rostratum prefers warmer, wetter environments, and has been found on a number of different plant species. They infect plants and in some cases precipitate tissue death. Once the plant dies, the fungus can feast on the remains.

It could have found it's way into human patients through tainted steroids. Once inside a patient the fungus enters the dura matter, which encloses the spinal fluid and spinal cord. The fungus’ filaments were able to penetrate the dura matter, enter the spinal fluid and travel to the brain.

In some of the fatal cases, the fungal filaments began to grow in the brain, attracting platelets as well as white and red blood cells to aggregate around the filaments, forming a mass that could block blood vessels and initiate strokes. The exact mechanism of all the deaths is still unclear and the fungus’s confinement to just three lots of the drug also remains unexplained.

The tainted steroids can be traced back to New England Compounding Center (NECC) in Framingham, Massachusetts. NECC had shipped more than 17,000 doses of the injectable steroid methylprednisolone acetate to 76 facilities in 23 states.

Mold Testing - DIY Petri Method - Pro-Lab - Inaccurate?

We often receive calls and emails requesting mold testing services. We also are asked if the home tests are any good. Well, it really depends on how accurate of a test/results want. The Truth I can guarantee if you use a petri dish style spore capturing device and you send it to a lab, you will get results. The results will always show you have mold. Of course you have mold, mold spores are everywhere. You can put the petri dish anywhere and get results. They just won't be accurate results. On their website you will see fanfare and dropping corporate names as a way to bolster their product. In essence they might as well be selling tests for oxygen. Simply put they rely on the ignorance of the general public to sell their product. I can state with clarity, the results are not accurate nor indicative of the actual mold situation in your home. From an industry standard they would never be used to clear a project, post remediation. Which means their accuracy is poor...

Lung Infections Caused by Fungi in Soil

A recent study by researchers at Washington University School of Medicine in St. Louis found certain fungi in soil can cause a significant number of serious lung infections in 48 out of 50 states and the District of Columbia, including many areas long thought to be free of deadly environmental fungi. Histoplasma is one of the three main species of soil fungi that cause lung infections in the U.S. Historically, Histoplasma was found in the Midwest and parts of the East, Coccidioides in the Southwest, and Blastomyces in the Midwest and the South. But a growing number of case reports and anecdotes suggest that all three have expanded out of their traditional ranges in recent decades. People develop fungal lung infections after breathing in spores from fungi in the soil. The spores become airborne when the ground is disturbed by farming, landscaping, construction, or even just by people walking around in fungi-rich environ...

Fungi in Flour - What You Should Know

A study from 5 years ago found over 90% of wheat and corn flour samples in Washington, D.C., contained live fungi. Aspergillus and Fusarium are commonly the predominant types of mold found in wheat flour. Fusarium will grow on wheat while in the field and is the cause of a disease called blight or scab. Most farmers will use multiple techniques to help reduce plant disease. Crop rotation, using resistant varieties and fungicides and minimal irrigation are helpful. Post harvesting, workers sort the grains to remove contaminated wheat before grinding them into flour. While sorting removes most of the contaminated wheat, small amounts of fungi can still make it into the flour. Please realize, the flour you buy at the store is raw flour that still contains live microorganisms. Eating cake batter or cookie dough can lead to fungal ingestion.
