Bamboo mosaic virus before that. The natural host of this virus is bamboo. It is known to infect at least 12 different species in 7 different genera. In host range studies it has been shown to cause local lesions on "Chenopodium amaraticolor" and "Gomphrena globosa" and a systemic infection in barley ("Hordeum vulgare"), another member of the grass family, "Poaceae" or "Gramineae". Symptoms in bamboo include chlorotic mottling/mosaic patterns on the leaves which run parallel with the veins (Typical symptoms on leaves), necrotic streaking on the shoots and stem abortion. However, not all susceptible plants show recognizable symptoms. Bamboo mosaic virus "Bamboo mosaic
Nonpathogenic organisms Nonpathogenic organisms Nonpathogenic organisms are those that do not cause disease, harm or death to another organism and is usually used to describe bacteria. It describes a property of a bacterium - its ability to cause disease. Most bacteria are nonpathogenic. It can describe the presence of non-disease causing bacteria that normally reside on the surface of vertebrates and invertebrates as commensals. Some nonpathogenic microorganisms are commensals on and inside the body of animals and are called microbiota. Some of these same nonpathogenic microorganisms have the potential of causing disease, or being pathogenic if they enter the body, multiply and
