Bartonella ancashensis is a bacterium from the genus of Bartonella which has been isolated from blood from patients who suffered from verruga peruana in Caraz in Peru.Bartonella ancashensis is a human pathogen which may cause verruga peruana. It is not yet certain if Bartonella ancashensis causes verruga peruana, as it may not meet all of Koch's postulates. Still, there is not experimental reproduction of Peruvian wart in animals for affirm that bartonella ancashi causes the Peruvian wart.

So, the drug of choice is ciprofloxacin. In the chronic phase, the treatment used traditionally has been streptomycin for 10 days. Since 1975, rifampin has become the drug of choice for verruga peruana. However, failures of rifampin treatment have also been reported and resistance can develop.

Carrion's disease is caused by Bartonella bacilliformis. Recent investigations show that Candidatus Bartonella ancashi may cause verruga peruana, although it may not meet all of Koch's postulates. There has been no experimental reproduction of the Peruvian wart in animals and there is little research on the disease's natural spread or impact in native animals.

B. henselae and B. quintana can cause bacillary angiomatosis, a vascular proliferative disease involving mainly the skin, and other organs. The disease was first described in human immunodeficiency virus (HIV) patients and organ transplant recipients. Severe, progressive and disseminated disease may occur in HIV patients. Differential diagnoses include Kaposi´s sarcoma, pyogenic granuloma, hemangioma, verruga peruana, and subcutaneous tumors.

His father, Maxime Hans Kuczynski, was born in Berlin, then part of the German Empire. He was a bacteriologist who served in the German Army during World War I on the Balkan front. He was a renowned pathologist and tropical disease specialist, in particular expert on Verruga peruana or Carrion's disease. He trained at the Universities of Rostock and Berlin, where he was professor of pathology.

Neurological involvement is sometimes seen (neurobartonellosis) and the prognosis in this case is poor. The most feared complications are super-infections, mainly by enterobacteria such as Salmonella, or parasites such as Toxoplasma gondii and Pneumocystis. When the bacterium invades endothelial cells, it produces the chronic manifestation of the disease known as verruga peruana. This phase consists of a benign skin eruption with raised, reddish-purple nodules (angiomatous tumours).

It is also called the eruptive phase or tissue phase, in which the patients develop a cutaneous rash produced by a proliferation of endothelial cells and is known as "Peruvian warts" or "verruga peruana". Depending on the size and characteristics of the lesions, there are three types: miliary (1–4 mm), nodular or subdermic, and mular (>5mm). Miliary lesions are the most common. The lesions often ulcerate and bleed.

He discovered bacillus within their red blood cells. If the patients recovered from the acute phase, the bacillus changed shape to cocci; and if the patients developed characteristic skin lesions—hemangioma-like nodules in the skin and mucous membranes-the so-called "Verruga peruana", the bacteria disappeared from the peripheral blood. On October 5, 1905, during a scientific meeting, he announced his discovery. The first manuscript was published in 1909 in the journal Crónica Médica.

Daniel Alcides Carrión, in 1885, infected himself from the pus in the purple wart (verruga peruana) of a female patient. Carrión developed an acute form of bartonellosis now known as Carrion's disease or Oroya fever. This is a rare disease found only in Peru and certain other parts of South America. He kept detailed notes of his condition and succeeded in showing through this self-experiment that the chronic and acute forms were the same disease.

Sirk'i Qullu (Aymara sirk'i wart, qullu mountain,katari.org Aymara-Spanish dictionary: Sirk'i (s.) - Verruga; Qullu (s.) - Cerro. Montón de algo "wart mountain", also spelled Serkhe Kkollu, Serkhe Khollu, Serkhe Kollu, Serque Qollu) is a mountain in the Cordillera Real in the Andes of Bolivia, about 5,546 m (18,196 ft) high. It is located in the La Paz Department, at the border of the Pedro Domingo Murillo Province, La Paz Municipality, and the Sud Yungas Province, Yanacachi Municipality.

In mammals, each Bartonella species is highly adapted to its reservoir host as the result of intracellular parasitism and can persist in the bloodstream of the host. Intraerythrocytic parasitism is only observed in the acute phase of Carrión´s disease. Bartonella species also have a tropism for endothelial cells, observed in the chronic phase of Carrión´s disease (also known as verruga Peruana) and bacillary angiomatosis. Pathological response can vary with the immune status of the host.

He identified the cotton square-weevil as the major culprit and found an effective biological control for the pest. After this success he turned his attention to uncovering the vector for verruga peruana and Oroya fever, diseases endemic to the mountains of Peru that were responsible for thousands of deaths. Townsend eventually identified a sandfly, Lutzomyia verracarum, as the disease vector. Townsend returned to the U.S. in 1914 and was employed by the USDA as a specialist on parasitic flies and curator of the Diptera collection at the U.S. National Museum.

Carrión described the disease in the course of what proved to be a fatal experiment upon himself in 1885, in order to demonstrate definitively the cause of the illness. He was inoculated by close friends with blood which had been taken from a wart of a 14-year-old patient.Top 10 Researchers Who Experimented On Themselves; Top Tenz; accessed ??? Carrión's aim was to prove a link between the acute blood stage of Oroya fever with that of the later chronic form of the disease, called verruga peruana, typified by numerous red, wart-like dermal nodules.

The parasite Leishmania donovani is the main causative agent of visceral leishmaniasis (VL) in India, Nepal, and Bangladesh, where it is transmitted by the sand flies of the species Phlebotomus argentipes. This species of sand flies was on the brink of elimination in India during the 1960s following the widespread use of DDT for malaria control. However, there was a resurgence in their population a decade later. Phlebotomus species are also vectors for bartonellosis, verruga peruana, and pappataci fever, an arboviral disease caused by sandfly fever viruses such as the Naples and Sicilian strains of the genus Phlebovirus (family Bunyaviridae), which also includes the closely related Toscana virus.

Numerius Fabius Ambustus was an ancient Roman commander who was the son of Marcus Fabius Ambustus, and brother to Caeso and Quintus. In 406 BC, he and his forces captured the Volscian city of Anxur (modern Terracina) by securing the high ground above the town, from which they were able to launch attacks against its walls. When the town's defenders attempted to respond to these harassing attacks, the remainder of Numerius' forces used escalade to scale the walls and enter the town. After the victory, his forces began to torture the inhabitants of the city in retaliation for the Volscian massacre of the Roman garrison at Verruga in which the Roman prisoners had been horribly tortured.

Bartonella bacilliformis is the etiologic agent of Carrion's disease or Oroya fever (acute phase of infection), and verruga peruana or Peruvian wart (chronic phase of infection). The acute phase of the disease is a life-threatening disease characterized by massive invasion of Bartonella to human red blood cells and consequently acute hemolysis and fever. If the infection is not treated, the case fatality rate is 40 to 85% Patients in this phase of the infection can be complicated by overwhelming infections, primarily by enterobacteria (Salmonella spp) and parasites (Toxoplasma gondii, Pneumocystis jirovecii). The chronic phase is characterized by benign eruptive lesions that are pruritic and bleeding, and other symptoms like malaise and osteoarticular pain.

The disease was named after medical student Daniel Alcides Carrión from Cerro de Pasco, Peru. Carrión described the disease after being inoculated at his request with the pus of a skin lesion from patient Carmen Paredes in 1885 by Doctor Evaristo M. Chávez, a close friend and coworker in Dos de Mayo National Hospital. Carrión developed the disease three weeks after the inoculation and kept a meticulous record of clinical symptoms and signs until the disease rendered him incapable of the task and he died at age 28 several weeks later--October 5, 1885. Carrión proved that Oroya fever and verruga peruana were two stages of the same disease, and not two different diseases as was thought at the time.
