There also appears to be an increased rate of anal cancer in high-risk groups (in particular, men who have sex with men). This is unsurprising considering the link between anal cancer and human papillomavirus (HPV), and the fact that cervical cancer, also caused by HPV, is considered an AIDS-defining condition. HIV Encephalopathy is a severe condition usually seen in end-stage disease.
Gray Mold. There are different types of fungus that grow on plants for a variety of reasons. Gray mold on plants is caused by overhead watering, low temperatures and low humidity levels. Poor air circulation around the plant is another problem with this type of fungus, as well as low nitrogen levels in the soil.
Fungi are an important group of plant pathogensâmost plant diseases are caused by fungiâbut fewer than 10% of all known fungi can colonize living plants (Knogge, 1996). Plant pathogenic fungi represent a relatively small subset of those fungi that are associated with plants.). Fungi may not be our next of kin, but they are more closely related to animals than they are to plants. We also recognize that organisms traditionally studied as fungi belong to three very different unrelated groups: the true fungi in Kingdom Fungi (Eumycota), the Oomycetes, and the slime molds (Fig. 1).
