Goat hair

Goat hair Domestic goats (many varieties) Domesticated worldwide... 

Other types of goats also produce usable fibers, but of much lower quality. This material is called common or ordinary goat hair or meadow goat hair. 

During the course of the next 1,500 years, Europe witnessed sporadic outbreaks of anthrax as they occurred in 14th century Germany and 17th century central Europe and Russia. The disease was classified as anthrax or charbon malin (Morens, 2003) in 1769 by the French physician Nicholas Fournier (Fournier, 1769 Morens, 2003). The name is derived from the black eschar lesions, the hallmark of cutaneous infection. Fournier also noted a link between those who worked with raw animal hair or wool and an increased susceptibility to disease. In the 18th century, an epidemic destroyed half of the sheep in Europe, possible evidence that anthrax was a major problem. Inhalation anthrax became known in the Victorian era as woolsorters disease however, infection was more often the result of contact with goat hair or alpaca than wool. 

Documented oil extraction dates back to 1650 b.c. when ripened olives were pressed by hand in Egypt using wooden pestles and stone mortars. The extracted ohve oil was hltered through goat hair filters and used as a lubricant. Sesame, hnseed, and castor oils were recovered in Egypt by hand pressing as far back as 259 b.c. (1). 

Anthrax spores, commonly found in the soil throughout the world (5), can cause infection when ingested by herbivore animals. Naturally occurring human infections follow exposnre to the infected animals or infected animal products. Occupational exposnre has been the most common cause of anthrax, with industrial mill wool sorters at greatest risk. From 1900 to 1978, there were 18 reported human cases in the United States, all in occupations associated with specific exposure, such as goat hair mill workers, tannery workers, and laboratory workers. Widespread animal vaccination programs have reduced animal mortality from anthrax and naturally occurring human anthrax is now a very rare disease (5). 

The iodine concentration of the hair also reflects iodine status very well (Anke and Risch 1979) (Table 9.4-28). Black hair or wool stores significantly more iodine than white hair or wool. Growing hair intensively incorporates iodine. Groppel (1986, Grabe-kies et al. 2002) recommended iodine intake limits of 200 pg kg feed DM for white goat hair, 300 pg kg DM for white sheep s wool, and 1000 pg kg DM for black cattle hair (Table 9.4-29). 

Complete chemical analysis of the medulla of human hair fibers has not been reported. Studies of the medulla of human hair are complicated because it has poor solubility and is difficult to isolate. In fact, most of the experimental work on medulla has been on African porcupine quill, horse hair, or goat hair medulla rather than medulla of human hair fiber. Rogers [66] has described the amino acid composition of medullary protein isolated from porcupine quill, and his results are summarized in Table 2-7. 

The vaccine should be given to industrial workers exposed to potentially contaminated animal products imported from countries in which animal anthrax remains uncontrolled. These products include wool, goat hair, hides, and bones. People in direct contact with potentially infected animals as well as laboratory workers should also be immunized. Vaccination is also indicated for protection against the use of anthrax in biological warfare. Approximately 150,000 service members received this licensed MDPH vaccine between 11 January and 28 February 1991 (25%-30% of the total U.S. forces deployed during the Persian Gulf War). 

Cutaneous Mo.st (about 95%) anthrax infections occur when the bacterium enters a cut or abrasion on the. skin, such as when handling contaminated wool, hides, leather or hair products (especially goat hair) of infected animals. Skin infection begins as a raised itchy bump that resembles an insect bite but within 1-2 days develops into a vesicle and then a painless ulcer, usually 1 -3 cm in diameter, with a characteristic black necrotic (dying) area in the center. Lymph glands in the adjacent area may swell. About 20% of untreated cases of cutaneous anthrax will result in death. Deaths are rare with appropriate antimicrobial therapy.

Anthrax, caused by Bacillus anthraciSy is a sporeforming, gram-positive rod that produces a lethal endotoxin. An effective vaccine was discovered by Pasteur in 1881. In the U.S., almost all human infections are cutaneous and limited to workers handling imported goat hair, wool, and hides from endemic regions with poor infectious disease controls.

Fibers that are taken from animals or hairy mammals such as Sheep, Wool, Goat (hair). Alpaca (hair). Horse (hair), etc., are animal fibers. Animal fibers generally comprise proteins, for example wool, silk, human hair, and feathers, etc. [99].
