Occurrence of Cryptosporidium and Giardia in suckling piglets in Norway

Occurrence of Cryptosporidium spp. and Giardia spp. in pigs at weaning

“…Giardia has been reported between 11 and 18 days of age (HAMNES et al, 2007). Fecal shedding of cysts of these protozoa was intermittent with a pattern similar to several other animal species (HAMNES et al, 2007).…”

“…These results agree with the findings of Guselle et al (2003) who evaluated cryptosporidiosis in swine. Hamnes et al (2007) also concluded that Giardia cysts are excreted in a non-continuous way in other animals, probably showing the same pattern in pigs.…”

“…Despite the positive findings, the cause of those diarrhea instances is not certain since no other copro-parasitological tests have been carried out in those pigs. Previously have reported significant association between diarrhea and Cryptosporidium positivity in piglets (HAMNES et al, 2007) end presence of Cryptosporidium was not significantly associated with decreased fecal consistency in pigs in Central Vietnam (NGUYEN et al, 2012). Daily pen cleaning with high pressure water, the use of disinfectants, adequate food, water from artesian wells given by nipple feeders, concrete floors or elevated pens and the habit of the pigs to defecate always in the same place are factors that reduce agent presence in the environment and must have contributed to the low parasitic occurrence observed in this study.…”

“…Cryptosporidium and Giardia may cause significant economic losses by weight reduction in piglets (HAMNES et al, 2007). Researchers in several countries reported a prevalence of Cryptosporidium spp.…”

“…It was particularly incident between the sixth and the 12 th weeks of life, which is a stage in the post-weaning period (MADDOX-HYTTEL et al, 2006;HAMNES et al, 2007;JOHNSON et al, 2008). Giardia has been reported between 11 and 18 days of age (HAMNES et al, 2007).…”
