“…Humans are infected mainly by C. parvum and C. hominis (Xiao et al, 2004;Xiao & Fayer, 2008), but some authors claim that there is a slight risk of C. felis infection in humans (Lucio-Forster, Griffiths, Cama, Xiao, & Bowman, 2010;Elwin, Hadfield, Robinson, & Chalmers, 2012;Pereira & Ferreira, 2012). In addition, C. felis transmission from cats to their owners has already been suggested (Beser et al, 2015).…”

We investigated the occurrence of Cryptosporidium oocysts shedding by domestic cats in an urban setting. The calculation of minimum sample size was based on an estimated prevalence of 10%, 5% absolute sampling error and a 5% significance level, resulting in 138 cats. A total of 612 owners of 2,290 cats had to be contacted for achieving the minimal sample size. In the end, only 55 owners accepted to participate in this investigation. Stool samples collected from 138 dogs were examined by microscopy using modified Kinyoun acid-fast staining, capture ELISA and nested-PCR followed by sequencing. Samples were considered positive when Cryptosporidium were detected by at least two diagnostic methods. Thirteen samples were positive (9.4%; 95% CI: 4.5 - 14.3). Cryptosporidium amplicons from seven out of the 13 samples were successfully sequenced and shared 99% genetic similarity to Cryptosporidium felis, GenBank access AF112575.1 was found. We concluded that Cryptosporidium infection is common in domestic cats from urban area and veterinary practitioners should guide cat owners to adopt preventive measures against the parasite to reduce the chance of infection in cats and householders.

“…Some investigations suggest that contact with animals increases the likelihood of Cryptosporidium infection in humans [39][40][41][42][43], but it remains controversial [26,32,33,44,45]. It is important to note that fecal samples from humans, dogs, and cats living in the same household are rarely analyzed in cross-sectional studies [40,45].…”

We investigated the zoonotic transmission of Cryptosporidium among the children (n = 188), dogs (n = 133), and cats (n = 55) living in 188 households. Fecal samples were examined using ELISA and confirmed via nested PCR. Coproantigens oocysts were detected in 3.7% of children, 8.3% of dogs, and 5.5% of cats. We found strong evidence of two cases of the zoonotic transmission of Cryptosporidium canis between children and dogs. Furthermore, four children and their respective pets (one dog and three cats) were infected with Cryptosporidium parvum, but we cannot exclude the hypotheses that the oocysts were transmitted from children to animals or that both hosts were infected by a shared source, such as contaminated water or food. The presence of an infected animal elevated the risk of zoonotic transmission by 129.7-fold (95% CI: 13.92–1209.68). Furthermore, sharing a bed with pets was identified as a risk factor for infection in children (OR: 9.9, 95% CI: 1.37–71.2). In conclusion, the zoonotic transmission of Cryptosporidium among children and pets cohabiting in the same household may be quite common, especially when infected animals lie or sleep on children’s beds. These findings unequivocally highlight the public health concern surrounding C. canis.

Introdução: A criptosporidiose é uma doença mundial, levando a quadros desde assintomáticos à diarreia grave. O presente estudo teve como objetivo detectar oocistos de Cryptosporidium spp. em idosos residentes em instituições de longa permanência na cidade de Lages, estado de Santa Catarina, Brasil, buscando avaliar a situação da parasitose, relativamente desconhecida na população idosa, foi avaliada por meio de um método diagnóstico fácil e de baixo custo, porém nem sempre realizado na rotina laboratorial. Métodos: Foram coletadas amostras dos exames Parasitológicos de fezes de 93 idosos residentes em instituições de longa permanência no período de setembro a novembro de 2015. Resultados: Os oocistos do protozoário foram detectados pela técnica de Ziehl-Neelsen modificada. A positividade para oocistos de Cryptosporidium spp. foi de 6,45% (6/93). Em relação ao sexo, a positividade foi de 8,9% (4/45) para mulheres e 2,1% (2/48) dos homens. Todos os pacientes tinham idade entre 60 e 70 anos. Em relação à consistência fecal, todas as amostras foram descritas como diarreia. Conclusão: A criptosporidiose é uma infecção parasitária importante e debilitante que afeta os idosos e precisa ser tratada. Os cuidadores devem estar cientes disso, para que tenham cuidados adequados, especialmente de higiene individual e uso de utensílios que podem transmitir a infecção aos demais idosos que residem nessas instituições.
