“…The overall prevalence of 20.5% Giardia infection identified in this study is similar to that previously reported in Denmark (17.1%) (Hansen et al, 2000), the former Yugoslavia (14.4%) (Nikolic et al, 2002), Norway (20.7%) (Hamnes et al, 2007) and Italy (15-32.1%) (Giangaspero et al, 2002;Capelli et al, 2003;Berrilli et al, 2004;Bianciardi et al, 2004;Capelli et al, 2006). Although Papini et al (2005) and Szénàsi et al (2007) found high prevalences of infection of 55.2% and 58.8% in kennelled dogs using a G. duodenalis-specific coproantigen ELISA, the discrepancy found by Szénàsi et al (2007) between prevalence as determined by this method and by microscopy (7.5%) suggests some caution should be applied in use of this diagnostic method (Cirak and Bauer, 2004;Mekaru et al, 2007).…”

Giardia duodenalis is a protozoan parasite of animals that is zoonotic. Given the capacity of this organism to spread via the faecal-oral route, animals held in overcrowded and unhygienic conditions are at high risk of infection. Faecal samples from dogs in three kennels in Rome were examined by microscopy and PCR for G. duodenalis, and the prevalence data generated were correlated with variables such as kennel identity, age of dog, length of time the dog had been kennelled and clinical signs.The overall prevalence of the parasite in the faecal samples was 20.5% and was higher in samples from the largest kennel, which had the greatest turnover of dogs, and in faecal samples from younger animals. Giardia cysts were found more frequently in diarrhoeic animals but were also found in dogs with no clinical signs. Although the finding that the majority of isolates were dog-specific rather than zoonotic genotypes suggests that the zoonotic risk from this pathogen is less than previously thought, the higher prevalence of infection in younger dogs may pose a specific public health issue as such animals are more frequently re-homed with families.

“…Despite the results of the current study, in some researches the frequency of Cryptosporidium infection was higher in young dogs (21,31,33,46). Some studies in comparison to the current study indicated that infection rates in female dogs were higher than male dogs, which may be due to reduced immunity at certain periods in female physiologic cycle (32).…”

Background: Cryptosporidium is a protozoan parasite that effects rodents, dogs, calves, humans, and cats. Infection with this parasite is known as cryptosporidiosis. Cryptosporidium spp. may induce clinical or subclinical signs in infected hosts. In the life cycle of this parasite infected dogs freely living in urban and rural areas of Khuzestan province are the definitive hosts that should be considered as a real problem in public health for humans. Objectives: This study aimed at determining the frequency of cryptosporidiosis in dogs in southwest of Iran. Methods: Overall, 350 fresh fecal samples were collected from domestic dogs living in 43 villages, from June 2012 to September 2013. All samples were investigated by Sheather's concentration method and fecal smears were stained with modified Ziehl-Neelsen followed by light microscope examination, and polymerase chain reaction (PCR). Results:The results revealed that frequency of Cryptosporidium infection was 8% and 12.3%, using direct smear and molecular method, respectively. Conclusions: The present findings indicated that domestic dog feces from southwest of Iran may contain zoonotic parasites such as Cryptosporidium spp. and may be a potential risk for humans and other animals, especially when they contaminate the environment. The role of dogs as source of human infection should be investigated by further studies.

“…Istedenfor å presentere disse funnene har Landvik konsentrert seg om en undersøkelse av unge hunder (5). Selv om den kumulative prevalensen fra denne studien, slik de er sitert, var relativt høy (44 % for Cryptosporidium og 21 % for Giardia), så var den individuelle prevalensen bare halvparten hos valpene (23 % for Cryptosporidium og 12 % for Giardia) og langt lavere hos tispene (< 3 % for Giardia og < 4 % for Cryptosporidium).…”
