Lice Infestations
Pediculosis is an infestation of lice from the sub-order Anoplura, family Pediculidae. Accordingly, the infestation with head lice is named pediculosis capitis, while this with body lice, pediculosis corporis. Although ''pediculosis'' in humans may properly refer to lice infestation of any part of the body, the term is sometimes used loosely to refer to ''pediculosis capitis'', the infestation of the human head with the specific head louse. Classification Pediculosis may be divided into the following types: :* Pediculosis capitis (Head lice infestation) :* Pediculosis corporis (Body louse infestation, also known as Pediculosis vestimenti, Vagabond's disease) :* Pediculosis pubis (Pubic louse infestation, also known as phthiriasis) Head lice Presentation Head-lice infestation is most frequent on children aged 3–10 and their families. Approximately 3% of school children in the United States contract head lice. Females aged 3–12 years are most commonly infested. Those of ...

Infectious Disease (medical Specialty)
Infectious diseases or ID, also known as infectiology, is a medical specialty dealing with the diagnosis and treatment of infections. An infectious diseases specialist's practice consists of managing nosocomial ( healthcare-acquired) infections or community-acquired infections and is historically associated with hygiene, epidemiology, clinical microbiology, travel medicine and tropical medicine. Scope Infectious diseases specialists typically serve as consultants to other physicians in cases of complex infections, and often manage patients with HIV/AIDS and other forms of immunodeficiency. Although many common infections are treated by physicians without formal expertise in infectious diseases, specialists may be consulted for cases where an infection is difficult to diagnose or manage. They may also be asked to help determine the cause of a fever of unknown origin. Specialists in infectious diseases can practice both in hospitals (inpatient) and clinics (outpatient). In hospital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trench Fever
Trench fever (also known as "five-day fever", "quintan fever" ( la, febris quintana), and "urban trench fever") is a moderately serious disease transmitted by body lice. It infected armies in Flanders, France, Poland, Galicia, Italy, Salonika, Macedonia, Mesopotamia, Russia and Egypt in World War I. Three noted cases during WWI were the authors J. R. R. Tolkien, A. A. Milne, and C. S. Lewis. From 1915 to 1918 between one-fifth and one-third of all British troops reported ill had trench fever while about one-fifth of ill German and Austrian troops had the disease. The disease persists among the homeless. Outbreaks have been documented, for example, in Seattle and Baltimore in the United States among injection drug users and in Marseille, France, and Burundi. Trench fever is also called Wolhynia fever, shin bone fever, Meuse fever, His disease, and His–Werner disease or Werner-His disease (after Wilhelm His Jr. and Heinrich Werner). The disease is cau ...

Cypermethrin
Cypermethrin (CP) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces. Exposure to sunlight, water and oxygen will accelerate its decomposition. Cypermethrin is highly toxic to fish, bees and aquatic insects, according to the National Pesticides Telecommunications Network (NPTN). It is found in many household ant and cockroach killers, including Raid, Ortho, Combat, ant chalk, and some products of Baygon in Southeast Asia. Uses Cypermethrin is used in agriculture to control ectoparasites which infest cattle, sheep, and poultry. Human exposure Cypermethrin is moderately toxic through skin contact or ingestion. It may cause irritation to the skin and eyes. Symptoms of dermal exposure include numbness, tingling, itching, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivermectin
Ivermectin (, '' EYE-vər-MEK-tin'') is an antiparasitic drug. After its discovery in 1975, its first uses were in veterinary medicine to prevent and treat heartworm and acariasis. Approved for human use in 1987, today it is used to treat infestations including head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis. It works through many mechanisms to kill the targeted parasites, and can be taken orally, or applied to the skin for external infestations. It belongs to the avermectin family of medications. William Campbell and Satoshi Ōmura won the 2015 Nobel Prize in Physiology or Medicine for its discovery and applications. It is on the World Health Organization's List of Essential Medicines, and is approved by the U.S. Food and Drug Administration as an antiparasitic agent. In 2018, it was the 420th most commonly prescribed medication in the United States, with more than 100,000 prescriptions. It is availab ...

Solenopotes Capillatus
''Solenopotes capillatus'' is known as the little blue cattle louse in the United States and the tubercle-bearing louse in Australia.Lloyd, J. E., et al. (2001)Persistent efficacy of doramectin topical solution against induced infestations of ''Bovicola bovis'' and ''Solenopotes capillatus''.''Veterinary Parasitology'' 102(3), 235-41. This louse is the smallest of the sucking lice that occur on cattle and is a relatively immobile species. They are found all around the world in distribution but are restricted mainly to areas with domestic livestock. The little blue cattle louse is most often found on the head of its host, primarily the face and jaw region, but sporadically is found on other body parts. It is relatively immobile so typically will not relocate on its host's body. The louse is spread by direct contact and is considered an ectoparasite."Ectoparasites - Solenopotes."

Bovicola Bovis
''Bovicola bovis'' (also called ''Damalinia bovis'' and the red louse) is a cattle-biting louse found all over the world. It is a common pest of cattle of all types and sizes. They are one of many of the lice in the order Phthiraptera, but are divided from their blood sucking cousins in the sub-order Anoplura by the fact that they feed only by chewing. This makes ''B. bovis'' a member of the sub-order Mallophaga.Koepsell, J. (2003)ADW: ''Bovicola bovis'': INFORMATION ''Animaldiversity.ummz.umich.edu'' Retrieved October 30, 2013 Biology These lice are composed of three major body regions: the head, thorax, and abdomen. The head of these lice is a dark red color while the rest of the body is yellowish-white. The abdomen has dark transverse bands that run horizontally across each segment along with sparse amounts of setae (hair-like structures). On average, these lice can span from 1-2mm in length as adults. They are dorso-ventrally flattened for ease of travel through the hairs of ...

Pubic Lice
Pediculosis pubis (also known as "crabs" and "pubic lice") is an infestation by the pubic louse, ''Pthirus pubis'', a wingless insect which feeds on blood and lays its eggs (nits) on mainly pubic hair. Less commonly, hair near the anus, armpit, beard, eyebrows, moustache, and eyelashes may be involved. It is usually acquired during sex, but can be spread via bedding, clothing and towels, and is more common in crowded conditions where there is close contact between people. The main symptom is an intense itch in the groin, particularly at night. There may be some grey-blue discolouration at the feeding site, and eggs and lice may be visible. Scratch marks, crusting and scarring may be seen, and there may be signs of secondary bacterial infection. Diagnosis is by visualising the nits or live lice, either directly or with a magnifying glass. Investigations for other sexually transmitted infections (STIs) are usually performed. First line treatment usually contains permethr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crab Louse
The crab louse or pubic louse (''Pthirus pubis'') is an insect that is an obligate ectoparasite of humans, feeding exclusively on blood. The crab louse usually is found in the person's pubic hair. Although the louse cannot jump, it can also live in other areas of the body that are covered with coarse hair, such as the perianal area, the entire body (in men), and the eyelashes (in children). Humans are the only known hosts of the crab louse, although a closely related species, ''Pthirus gorillae'', infects gorillas. The human parasite is thought to have diverged from ''Pthirus gorillae'' approximately 3.3 million years ago. It is more distantly related to the genus ''Pediculus'', which contains the human head and body lice and lice that affect chimpanzees and bonobos. Description An adult crab louse is about 1.3–2 mm long (slightly smaller than the body louse and head louse), and can be distinguished from those other species by its almost round body. Another distinguish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Body Lice
The body louse (''Pediculus humanus humanus'', also known as ''Pediculus humanus corporis'') is a hematophagic ectoparasite louse that infests humans. It is one of three lice which infest humans, the other two being the head louse, and the crab louse or pubic louse. Despite the name, body lice do not directly live on the host. They lay their eggs on fibres of clothing and only come into contact with the host whenever they need to feed. Since body lice cannot jump or fly, they spread by direct contact with another person or more rarely by contact with clothing or bed sheets that are infested. Body lice are disease vectors and can transmit pathogens that cause human diseases such as epidemic typhus, trench fever, and relapsing fever. In developed countries, infestations are only a problem in areas of poverty where there is poor body hygiene, crowded living conditions, and a lack of access to clean clothing. Outbreaks can also occur in situations where large groups of people ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhus
Typhus, also known as typhus fever, is a group of infectious diseases that include epidemic typhus, scrub typhus, and murine typhus. Common symptoms include fever, headache, and a rash. Typically these begin one to two weeks after exposure. The diseases are caused by specific types of bacterial infection. Epidemic typhus is due to ''Rickettsia prowazekii'' spread by body lice, scrub typhus is due to ''Orientia tsutsugamushi'' spread by chiggers, and murine typhus is due to ''Rickettsia typhi'' spread by fleas. Vaccines have been developed, but none are commercially available. Prevention is achieved by reducing exposure to the organisms that spread the disease. Treatment is with the antibiotic doxycycline. Epidemic typhus generally occurs in outbreaks when poor sanitary conditions and crowding are present. While once common, it is now rare. Scrub typhus occurs in Southeast Asia, Japan, and northern Australia. Murine typhus occurs in tropical and subtropical areas of the worl ...
