The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

Parasitic. A germ tube penetrates the nematode cuticle and vegetative growth initiates in the nematode pseudocoelom, eventually leading to sporulation of Pasteuria and the nematode death. |
|
Pasteuria species are ubiquitous in most environments and are found in nematodes in many different countries. First isolated from an Illinois soybean field in the mid-2000s |

The commercial production of Pasteuria nishizawae Pn1 involves cultivating and harvesting endospores. Pn1 is grown under controlled conditions to ensure high spore yield and purity. The process includes fermentation using nutrient-rich media, followed by separation and concentration of the endospores. |
