Resumo
Cryptosporidium spp. é um protozoário que completa seu ciclo biológico na superfície de células epiteliais do trato gastrintestinal, respiratório e urinário de mamíferos, aves, répteis, anfíbios e peixes. Foi incluído na Iniciativa das Doenças Negligenciadas da Organização Mundial da Saúde (OMS) por sua estreita relação à população com baixo poder aquisitivo e precárias condições de saneamento básico. Esse gênero de parasito causa doença clínica e subclínica em Psitaciformes, com detecção de Cryptosporidium meleagridis, Cryptosporidium baileyi, Cryptosporidium galli e dos genótipos I, II, III, IV e V. A calopsita é um dos psitacídeos mais vendidos atualmente, sendo frequentemente encontrada em residências. O contato próximo com humanos é motivo de preocupação, uma vez que pode ser reservatório desse coccídio intestinal, sendo imprescindível atentar para medidas de prevenção, controle e diagnóstico dessa enfermidade parasitária. Os métodos baseados na microscopia são mais utilizados para o diagnóstico de Cryptosporidium spp., por serem menos onerosos. No entanto, apenas a caracterização molecular é capaz de identificar a espécie de Cryptosporidium spp. Em relação ao tratamento dessa enfermidade em aves, é importante ressaltar que ainda não há quimioterapia efetiva disponível. Boas condições de higiene e saneamento básico são essenciais, a fim de prevenir e controlar surtos dessa enfermidade em humanos e animais.
Cryptosporidium spp. is protozoa that complete their biological cycle on the surface of epithelial cells of the gastrointestinal, respiratory and urinary tract of mammals, birds, reptiles, amphibians and fish. This parasite was included in the World Health Organization's Neglected Diseases Initiative because of its close relationship to the population with low purchasing power and poor basic sanitation conditions. This infection causes clinical and subclinical disease in Psitaciformes with detection of Cryptosporidium meleagridis, Cryptosporidium baileyi, Cryptosporidium galli and genotypes I, II, III, IV and V. The cockatiel is one of the best selling psittacines currently found in homes. Close contact with humans is cause for concern, since they may be reservoirs of this coccidia, being essential to watch for measures of prevention, control and diagnosis of this parasitic disease. The methods based on the microscopy are more used for the diagnosis of cryptosporidiosis, because they are less expensive. However, only molecular characterization is able to identify the species of Cryptosporidium spp. in relation to the treatment of this disease in poultry, it is important to emphasize that there is still no effective chemotherapy available. Good hygiene and basic sanitation conditions are essential, in order to prevent and control disease in animals and animals.
