Relation between Neospora caninum and abortion in dairy cows: Risk factors and pathogenesis of disease

Retracted: Prevalence of Toxoplasma gondii and Neospora caninum in different types of raw milk and traditional dairy product samples

“…In keeping with this, raw milk and traditional dairy products are not necessarily safe, as evidenced by higher rates of foodborne illnesses associated with their consumption (Angulo, LeJeune, & Rajala‐Schultz, ). Recognized documents revealed that consumption of raw milk and traditional dairy products is responsible for occurrence of dangerous protozoan foodborne diseases like toxoplasmosis in humans and neosporosis in animals (Hussain, Stitt, Szabo, & Nelan, ; Klauck et al, ).…”

“…Contrariwise, the only established definitive hosts of N. caninum are dogs, gray wolfs, coyotes, and dingoes that causes a serious disease particularly in ruminants (Belluco et al, 2017;Boas et al, 2015;Donahoe et al, 2015;Dubey, 2003;Hussain et al, 2017;Jones & Dubey, 2012;Klauck et al, 2016;McCann et al, 2008;Oshiro et al, 2015). Recorded data showed that intermediate hosts of T. gondii and N. caninum become infected in two ways of vertical (transplacental) and horizontal (ingestion of oocysts shed in milk and meat) (Belluco et al, 2017;Boas et al, 2015;Donahoe et al, 2015;Dubey, 2003;Hussain et al, 2017;Jones & Dubey, 2012;Klauck et al, 2016;McCann et al, 2008;Oshiro et al, 2015). Thus, contaminated milk and dairy products (particularly traditional dairy products) play an imperative role in the distribution of T. gondii and N. caninum infections to human (Ayinmode, Akinseye, Schares, & Cadmus, 2017;Gos et al, 2017).…”

A study of Neospora caninum antibody seroprevalence ın dairy cows in Turkey

“…However, congenitally infected calves with low calving syndrome have low chance of survival and may have neural pathological clinical implications. Sometimes, as a result of congenital encephalomyelitis, calves with paresis and dysphoria may occur in the hind legs and neurological reflections may occur after weeks of birth (Dubey and Schares, 2011;Klauck et al, 2016). In this study, there was a calf with neurological signs.…”

“…Transplacental transmission during pregnancy can occur in pregnant cows infected with N. caninum. Congenitally infected fetus birth or abortion is closely related to the immunity of pregnant cow, placenta and fetus (Klauck et al, 2016). Some studies regarding neosporosis have shown that fetal infection decreases with the rise of the number of gestations, and consequently with the animal's age, mainly be-cause animals acquire immunity against the parasite, so, the animals may not show high levels of antibody against N. caninum.…”

“…A soroprevalência de N. caninum foi avaliada entre 15% a 29% na região sul, sudeste e centro-oeste (RAGOZO et al, 2003) e 14% a 35% na região nordeste (GONDIM et al, 1999;MINERVINO et al, 2008). Nos rebanhos de corte, a soroprevalência foi de 14% (MARQUES et al, 2011) e 13% (MOURA et al, 2012, enquanto no rebanho de leite foi de 11% (VILAS-BOAS et al, 2015) e 44% (KLAUCK et al, 2016) chegando até 97% (GUEDES et al, 2008). As perdas econômicas por neosporose no Brasil são estimadas em US$101 milhões na pecuária de corte e US$51 milhões na pecuária de leite (REICHEL et al, 2013).…”
