Baylisascaris procyonis: An Emerging Helminthic Zoonosis
Baylisascaris procyonis, a roundworm infection of raccoons, is emerging as an important helminthic zoonosis, principally affecting young children. Raccoons have increasingly become peridomestic animals living in close proximity to human residences. When B. procyonis eggs are ingested by a host other than a raccoon, migration of larvae through tissue, termed larval migrans, ensues. This larval infection can invade the brain and eye, causing severe disease and death. The prevalence of B. procyonis infection in raccoons is often high, and infected animals can shed enormous numbers of eggs in their feces. These eggs can survive in the environment for extended periods of time, and the infectious dose of B. procyonis is relatively low. Therefore, the risk for human exposure and infection may be greater than is currently recognized
HUMAN CYCLOSPORIASIS DIAGNOSIS: REPORT OF A CASE IN SĂO PAULO, SP, BRAZIL
Diagnosis of the human cyclosporiasis is reported in SĂŁo Paulo, SP, Brasil. Cyclospora cayetanensis has been identified in the feces of a patient by a modified Kinyoun staining method, with later sporulation in a solution of 2.5% potassium dichromate. The probability that this parasite is the eventual cause of gastrointestinal disturbances in the country was stimulated by this finding, which was arrived at by a simple technique. It had been kept in mind that the disease was expressing itself mainly among immunocompromised patients, whose number is increasing; especially in those with acquired immunodeficiency syndrome (AIDS), which is caused by the human immunodeficiency virus (HIV).<br>Ă relatado o diagnĂłstico de ciclosporĂase humana em SĂŁo Paulo, SP, Brasil. Cyclospora cayetanensis foi encontrada nas fezes de um indivĂduo atravĂ©s de exame pelo mĂ©todo de coloração de Kinyoun modificado, com posterior esporulação em dicromato de potĂĄssio a 2,5%. Esta verificação deve estimular a necessidade de considerar a ciclosporĂase como eventual causa de distĂșrbios gastrointestinais no paĂs, podendo ela ser reconhecida atĂ© mesmo por meio de tĂ©cnica razoavelmente simples. Foi ainda lembrado que esta parasitose vem adquirindo expressividade sobretudo pelo fato de nĂŁo raramente acometer imunodeprimidos, agora cada vez mais numerosos em especial como decorrĂȘncia da infecção pelo vĂrus da imunodeficiĂȘncia humana (HIV), que causa a sĂndrome da imunodeficiĂȘncia adquirida (AIDS)
