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.
What Is Rust Fungus? Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales(previously also known as Uredinales). About 7800 species are known. Rusts can affect a variety of plants; leaves, stems, fruits and seeds. Rust is most commonly seen as coloured powder, composed off tiny aeciospores which land on vegetation producing pustules, or uredia, that form on the lower surfaces.
