“…Em alojamentos coletivos e com aglomeração, o contato entre animais é maior com consequente maior chance de infecção. Couto et al (2015) reportaram que apenas 8,5% de bezerros criados em alojamentos individuais e com comedouros e bebedouros altos apresentaram oocistos nas fezes comparado aos 21,9% de bezerros alojados em baias coletivas e com comedouros e bebedouros baixos. Animais com diarreia representam outro fator de risco para a disseminação do Cryptosporidium.…”

O objetivo desta revisão foi determinar os potenciais fatores de risco para a ocorrência de criptosporidiose bovina no Brasil. Foi adotado como procedimento metodológico a revisão sistemática. A busca foi feita nas bases de dados Science Direct, Scopus, Web of Science e Scielo. Como estratégia de busca foram usados os descritores Cryptosporidium, cryptos-poridiosis, cattle, calves, Brazil. Foram selecionados 9 estudos conduzidos em diferentes estados do Brasil, com ocorrências entre 2008 a 2019. A ida-de dos animais avaliados variou de 0 a mais que 36 meses. Os principais fatores de risco determinados foram a pouca idade dos animais, alojamento coletivo, presença de animais com diarreia, contato com outros animais e raça leiteira. Concluiu-se que os principais fatores de risco foram animais jovens, presença de animais com diarreia, contato com outros animais, ani-mais de raça leiteira e alojamento coletivo.

“…In collective buildings, the contact among animals is higher, resulting in a greater probability of infection. Couto et al (2015) reported that only 8.5% of calves reared in individual pens, with high feeders and drinkers, showed oocytes in their feces, compared to the 21.9% of calves reared in collective pens, with low feeders and drinkers, showing oocytes in their feces. Animals with diarrhea contribute to the dissemination of Cryptosporidium in the environment, as mentioned by Toledo et al (2017) and Cruvinel et al (2020).…”

Protozoa of the genus Cryptosporidium are parasites capable of causing animal rearing losses due to diarrhea outbreaks. This review aimed to determine the prevalence of and potential risk factors for bovine cryptosporidiosis in Brazil. The search was carried out in the databases Science Direct, Scopus, Web of Science, and SciELO. The search strategy used the descriptors “Cryptosporidium,” “cryptosporidiosis,” “cattle,” “calves,” and “Brazil.” Nine studies conducted in different Brazilian states between 2008 and 2019 were selected. The age of the evaluated animals ranged from 0 to >36 months. The main risk factors were the low age of the animals, collective pens, presence of diarrhea, contact with other animals, and dairy breed. The average prevalence rate was 30.51%. The species identified were C. ryanae, C. parvum, and C. bovis. Optical microscopy was used as a diagnostic method for oocysts in fecal samples and to determine the species, and PCR was used in three studies. The average prevalence of Cryptosporidium spp. in cattle in Brazil was 30.51%, ranging from 10.2 to 62.5%. The main risk factors found were young animals, the presence of animals with diarrhea, contact with other animals, dairy breeds, and collective pens.
