A molecular epidemiological survey of Cryptosporidium from water buffalo (Bubalus bubalis) in the Northern Territory in Australia was conducted. Fecal samples were collected from adult farmed (n = 50) and wild buffalo (n = 50) and screened using an 18S quantitative PCR (qPCR). Positives were typed by sequence analysis of 18S nested PCR products. The qPCR prevalence of Cryptosporidium species in farmed and wild buffalo was 30 and 12 %, respectively. Sequence analysis identified two species: C. parvum and C. bovis, with C. parvum accounting for ~80 % of positives typed from the farmed buffalo fecal samples compared to 50 % for wild buffalo. Subtyping at the 60 kDa glycoprotein (gp60) locus identified C. parvum subtypes IIdA19G1 (n = 4) and IIdA15G1 (n = 1) in the farmed buffalo and IIaA18G3R1 (n = 2) in the wild buffalo. The presence of C. parvum, which commonly infects humans, suggests that water buffaloes may contribute to contamination of rivers and waterways with human infectious Cryptosporidium oocysts, and further research on the epidemiology of Cryptosporidium in buffalo populations in Australia is required.

“…Dessa forma, a caracterização molecular de isolados de diferentes origens (animal, humana e ambiental) tem sido amplamente usada com o intuito de investigar o potencial zoonótico das espécies ou genótipos do protozoário (XIAO;FAYER, 2008). Atualmente, 26 espécies de Cryptosporidium são reconhecidas, sendo nove capazes de infectar humanos (ASSIS et al, 2013;SHARMA et al, 2013;KATZER, 2013), sendo que diversos grupos de subtipos e sub-genótipos de Cryptosporidium têm sido identificados, dos quais os subtipos Cryptosporidium parvum IIa e IId foram identificados como zoonóticos (PLUTZER; KARANIS, 2009;HELMY et al, 2013).…”

Criptosporidiose em animais domésticos: aspectos epidemiológicos

ResumoEstudos referentes á criptosporidiose são essenciais, devido sua relevância em saúde pública e por sua patogenicidade em animais de produção e de companhia. Nos últimos 20 anos, houve uma rápida expansão das pesquisas envolvendo o gênero Cryptosporidium, em grande parte relacionada a estudos moleculares, propiciando a descrição de várias espécies, genótipos e subtipos do parasito. A caracterização molecular de isolados de diferentes origens (animal, humana e ambiental) tem sido amplamente usada com o intuito de investigar o potencial zoonótico deste protozoário. As formas de transmissão documentadas são de animais para o ser humano, de pessoa para pessoa, por meio de ingestão ou do uso de água destinada a lazer contaminada direta ou indiretamente com oocistos esporulados. A elevada taxa de animais naturalmente infectados e a susceptibilidade ao protozoário justificam a importância de se atentar para a ocorrência desta enfermidade. Assim, são demonstrados aspectos epidemiológicos desta zoonose em animais domésticos.

The present study aimed to analyze the occurrence of infection by Cryptosporidium spp. in mares and their respective foals. This study was carried out in 11 farms located in the municipalities of Araçatuba, Birigui, Guararapes and Santo Antônio do Aracangua, in the northwest region of the State of Sao Paulo, from November 2010 to March 2011. A total of 98 mares and 98 foals of several breeds were analyzed; among foals, 59 were males and 39 females, aged from three to 330 days. Feces were collected directly from the rectal ampulla, purified and processed according to modified Kinyoun stain. Occurrence of Cryptosporidium spp. was 21.4% (21/98) for foals and 18.4% (18/98) for mares. Occurrence of Cryptosporidium spp. had significant association with breeds and age of animals. Results obtained led to the conclusion that foals older than two months and Mangalarga animals are less susceptible to the occurrence of Cryptosporidium spp.Keywords: Cryptosporidium, frequency, mares, foals. ResumoO presente estudo teve como objetivo analisar a ocorrência da infecção por Cryptosporidium spp. em éguas e seus respectivos potros. Este estudo foi realizado em 11 fazendas localizadas nos municípios de Araçatuba, Birigui, Guararapes e Santo Antônio do Aracangua, na região Noroeste do Estado de São Paulo, de novembro de 2010 a março de 2011. Um total de 98 éguas e 98 potros de diversas raças foram analisados, sendo que, entre os filhotes, 59 eram machos e 39 fêmeas, cujas idades variavam de três até 330 dias. Fezes foram colhidas diretamente da ampola retal, purificadas e processadas pela técnica de Kinyoun modificada. A ocorrência de Cryptosporidium spp. observada foi de 21,4% (21/98) para potros e 18,4% (18/98) para éguas. A ocorrência de Cryptosporidium spp. teve uma associação significativa com a raça e a idade dos animais. A partir dos resultados obtidos, conclui-se neste estudo que potros com idade superior a dois meses e animais da raça Mangalarga foram menos susceptíveis à ocorrência de Cryptosporidium spp.Palavra-chave: Cryptosporidium, frequência, éguas, potros.
