Bioquell's HPV technology has been tested and proven effective against many organisms including bacteria, bacterial endospores, viruses, bacteriophage, fungi, nematodes and protozoa.
1) As the spher ules mature, they produce and fill with hundreds to thousands of endospores (Figure 2).
Herbivores are often infected whilst grazing, especially when eating rough, irritant or spiky vegetation: the vegetation has been hypothesized to cause wounds within the gastrointestinal tract permitting entry of the endospores into the tissues.
It occurs naturally in soil and mainly affects hoofed animals including goats, cattle, and sheep that ingest endospores (11-13).

While Anthrax does not spread directly from one infected animal or person to another, it is spread by endospores that are able to survive in harsh conditions for long periods of time, and those spores can lie dormant for years and possibly decades.

The unusual resistance of the resting endospores to chemical and physical agents, the developmental cycle of endospore formation, their morphology, and the production of their own antibiotics provides these bacteria with a survival advantage.
Additionally, none of the isolates possessed capsules or endospores.
Coccidioides immitis can be distinguished from Crecurvatusby identifying internal cleavage or endospores and by the lack of budding.
