Broad-spectrum antibiotic estimated 10-100 trillion multiple organisms that colonize the human body. As a side-effect of therapy, antibiotics can change the body's normal microbial content by attacking indiscriminately both the pathological and naturally occurring, beneficial or harmless bacteria found in the intestines, lungs and bladder. The destruction of the body's normal bacterial flora is thought to disrupt immunity, nutrition, and lead to a relative overgrowth in some bacteria or fungi. An overgrowth of drug-resistant microorganisms can lead to a secondary infection such as "Clostridium difficile" ("C. diff") or candidiasis ("thrush"). This side-effect is more likely with the use of broad-spectrum antibiotics, given
Clavarioid fungi on wood or on decaying herbaceous stems and fallen leaves. Some species, particularly in the genera "Clavulina" and "Ramaria", are known to be ectomycorrhizal (forming a beneficial association with the roots of living trees). Species in the genera "Ertzia", "Multiclavula", "Lepidostroma", and "Sulzbacheromyces" are lichenized and grow in association with algae. Clavarioid fungi have a worldwide distribution, though some genera—such as "Aphelaria" and "Lachnocladium"—are principally tropical. They are one of the most common of the four fungi groupings. Clavarioid fungi The clavarioid fungi are a group of fungi in the "Basidiomycota" typically having erect, simple or branched basidiocarps (fruit bodies)
