“…This zoonosis has been reported worldwide (Itoh et al, 2011;Pan et al, 2018;Paoletti, Iorio, Capelli, Sparagno, & Giangaspero, 2008;Upjohn et al, 2010), and, in Brazil, the prevalence of chronic giardiasis in adult dogs is estimated to range from 10% to 20% (Bouzid, Halai, Jeffreys, & Hunter, 2015) although higher rates have been reported (Katagiri & Oliveira-Sequeira, 2008;Volotao et al, 2011).…”

Giardia duodenalis is a pathogenic gastrointestinal waterborne protozoan in domestic mammals and humans (Acha & Szyfres, 2003). The primary clinical symptoms associated with giardiasis in dogs are diarrhoea, vomiting and weight loss, but most of the infections are asymptomatic (Olson, Olson, & Wallis, 2002). The life cycle of G. duodenalis is direct: cysts eliminated in the faeces of the infected host contaminate the environment and water and may be ingested by a susceptible host or thru the faecal-oral route with host to host

“…Many recent epidemiological studies have reported G. duodenalis infections in dogs in China [ 10 , 11 , 19 , 27 ], Japan [ 8 ], and Brazil [ 4 ]. In Heilongjiang and Shanghai, China [ 11 , 27 ], zoonotic genetic assemblages A and B have been observed in pet dogs.…”

Detection and multilocus genotyping of Giardia duodenalis in dogs in Sichuan province, China

Giardia duodenalis (also known as G. intestinalis) is a flagellated protozoan that parasitizes the small intestine and is a common causal agent of zoonotic infections in humans and animals. To assess the genetic diversity and zoonotic transmission potential of G. duodenalis in stray dogs, 159 fecal specimens were collected from dogs in Chengdu, Yaan, and Leshan in Sichuan province, China. Of the 159 fecal samples from stray dogs, 18 (11.3%) were G. duodenalis-positive based on nested PCR amplification of the beta giardin (bg) gene, and the occurrence varied from 1.8% to 35% in different cities. Dog-specific assemblages C (n = 9) and D (n = 9) were identified. The glutamate dehydrogenase (gdh) and triosephosphate isomerase (tpi) genes of all bg-positive isolates were characterized. A total of 16 and 8 isolates were positive for the gdh and tpi genes, respectively. Two novel sequences of the bg locus were detected among genetic assemblage D isolates, and one novel gdh sequence and four novel tpi sequences were identified among genetic assemblage C isolates. Mixed infections of assemblages C and D were also detected. Assemblages A and B, which have high zoonotic potential, were not detected. Our results show that G. duodenalis is prevalent and a cause of diarrhea in dogs in Sichuan province, China.

“…However, these differences may be independent of the investigated regions because the wide variations of G. duodenalis and Cystoisospora spp. prevalences have been reported in breeding kennels and pet shops (Itoh et al 2005(Itoh et al , 2011. Considering that 88.3% of dogs (2,089/2,365) were kept indoors, the overall lack of difference in parasites according to investigated regions may be unsurprising.…”

Giardia and other intestinal parasites in dogs from veterinary clinics in Japan

The present study is the first report that describes the national survey of intestinal parasites in private household dogs brought to veterinary clinics in Japan. A total of 2,365 fresh feces were collected. Giardia-specific coproantigen was examined by ELISA kit (SNAP(®) Giardia, IDEXX Laboratories, Inc.; Maine, USA). Other intestinal parasites were determined microscopically using the formalin-ethyl acetate sedimentation technique. According to age categories, Giardia duodenalis, Cystoisospora spp., Toxocara canis, Toxascaris leonina, and Strongyloides spp., at ≦6-months-old showed significantly (P< 0.0001, P < 0.001 or P < 0.01, respectively) higher prevalence compared to >6 months old (31.5% vs. 2.3%, 9.1% vs. 0.05%, 1.8% vs. 0.4%, 1.1% vs. 0%, and 1.1% vs. 0.05%, respectively). In clinical categories, prevalences of G. duodenalis (14.8%) and Cystoisospora spp. (4.7%) in symptomatic dogs were significantly (P < 0.05, respectively) higher than those in asymptomatic ones (7.9% and 1.6%, respectively). G. duodenalis and Cystoisospora spp. were dominant parasites in private household dogs in Japan, especially ≦6-month-old dogs.
