Milker's Nodule

	Milker's Nodule Milker's nodules are a cutaneous condition that is most commonly transmitted from the udders of infected cows. Milker's nodule is caused by Paravaccinia virus. The disease in humans is nearly identical to Orf. __TOC__ Pathogen Milker's nodules is a zoonotic dermatosis. It was caused by double-stranded DNA virus of the ''Parapoxvirus'' genus. ''Parapoxvirus'' usually presents in the saliva, nasal secretions, and in lesions over the udder, trunk, and limbs of affected bovine cattle. It may transmitted by direct or indirect contact of lesion.

picture info	Paravaccinia Virus Pseudocowpox is a disease caused by the Paravaccinia virus or Pseudocowpox virus, a virus of the family ''Poxviridae'' and the genus ''Parapoxvirus''. Humans can contract the virus from contact with livestock infected with Bovine papular stomatitis and the disease is common among ranchers, milkers, and veterinarians. Infection in humans will present with fever, fatigue, and lesion on the skin. Signs and symptoms Paravaccinia virus presents itself with blisters, nodules, or lesions about 4 mm in diameter, typically in the area that has made contact with livestock that is infected with bovine papular stomatitis. Lesions may begin forming as late as three weeks after contact has been made with an infected animal. In rare cases, lesions may be seen systemic. General signs of infection are also common, such as fever and fatigue. Infected livestock may present with blisters or lesions on their udders or snout. Often, however, infected livestock show little to no symptoms. Mecha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Orf (disease) Orf is a farmyard pox, a type of zoonosis. It causes small pustules in the skin of primarily sheep and goats, but can also occur on the hands of humans. A pale halo forms around a red centre. It may persist for several weeks before crusting and then either resolves or leaves a hard lump. There is usually only one lesion, but there may be many, and they are not painful. Sometimes there are swollen lymph glands. It is caused by a ''Parapoxvirus''. It can occur in humans who handle infected animals or contaminated objects. One third of cases may develop erythema multiforme. Once resolved, a person can still be infected again. Generally, treatment options are limited. Injecting the lesion with cidofovir or applying imiquimod has been tried. It is sometimes necessary to cut them out. The vaccine used in sheep to prevent orf is live and has been known to cause disease in humans. The disease is endemic in livestock herds worldwide. A recent outbreak emerged in southwest Ethiopia betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Zoonosis A zoonosis (; plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite or prion) that has jumped from a non-human (usually a vertebrate) to a human. Typically, the first infected human transmits the infectious agent to at least one other human, who, in turn, infects others. Major modern diseases such as Ebola virus disease and salmonellosis are zoonoses. HIV was a zoonotic disease transmitted to humans in the early part of the 20th century, though it has now evolved into a separate human-only disease. Most strains of influenza that infect humans are human diseases, although many strains of bird flu and swine flu are zoonoses; these viruses occasionally recombine with human strains of the flu and can cause pandemics such as the 1918 Spanish flu or the 2009 swine flu.

picture info	List Of Cutaneous Conditions Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm th ...
