Individual acoustic guitar strings can be found in the Single Strings section. Although the strings that most acoustic guitars use are commonly called steel strings (and they do have steel cores), the wound strings will almost always be wound with bronze.
Many people with hookworm infection do not have symptoms. However at the start of a hookworm infection, an itchy, red, raised rash (ground itch) may develop where the larvae penetrate the skin. The movement of the larvae through the lungs can cause fever, coughing, and wheezing.
While mild cases of hookworm infection may cause diarrhea and weight loss, severe parasitism can cause anemia due to blood loss from the intestines where the worms attach themselves. In these cases, a cat's feces will often appear black and tarry due to the presence of digested blood in the feces.
