“…Older lambs demonstrate delayed growth, and adults are generally refractory to infection and illness (XIAO et al, 1993), but can eliminate oocysts in the feces, thereby contaminating the environment (MAJEWSKA et al, 2000;ZUCATTO et al, 2015). In Brazil, studies on cryptosporidiosis in ruminants have primarily been performed in the Southeast, mainly in the states of Rio de Janeiro (COSENDEY et al, 2008;FIUZA et al, 2011), Minas Gerais (GARCIA & LIMA, 1993;GARCIA & LIMA, 1994;LIMA et al, 2013), andSão Paulo (AQUINO et al, 2015;COELHO et al, 2016;FEITOSA et al, 2004;FÉRES et al, 2009;PAZ E SILVA et al, 2013SEVÁ et al, 2010;SILVA-JUNIOR et al, 2011). In the state of Paraná, infection with Cryptosporidium was evaluated in captive birds (NAKAMURA et al, 2009), dogs with diarrhea (NAVARRO et al, 1997), horses (FUJII et al, 2014, wild birds and mammals (SNAK et al, 2015), cattle (TOLEDO et al, 2017 and sheep (SNAK et al, 2017).…”
