“…This favours easy maturation of larvae and oocysts as it is not the case in the temperate countries where less prevalences were reported. The overall prevalence intestinal parasites of (59.3%) is similar with the findings of Papini et al (2005) and Szenasi et al (2007) who discovered high prevalence of infection of 55.2% and 58.8% in dogs respectively elsewhere.…”

Uncontrolled population of stray and domicile dogs with intestinal protozoan in close proximity to increasing densities of human population in urban environments is a common fact in developing countries, in conjunction with the lack of veterinary attention and zoonotic awareness, increases the risks of disease transmission. We examined using standard method 108 stool specimens of stray and domicile dogs collected randomly from Ilorin, state capital of Kwara State, Nigeria for intestinal protozoan. The prevalence of intestinal parasites from both stray and domicile dogs was 64(59.3%). Three parasites were encountered; Anchylostoma sp, Cryptosporidium sp and Isospora sp. Female dogs were more infected (48.9%) than male dogs (11.1%) (P<0.001) while the stray dogs had more intestinal parasitic infection (68.3%) than domicile dogs (46.7). More of Cryptosporidium sp was observed among strayed dogs (36.5%). Double infection was highest in stray dogs (12.7%) than in domicile dogs (4.4%) but not statistically significant (p=0.051). Consistent sanitary education must be included in public health government actions as a first step for the control of intestinal parasites in dogs and good sanitation and hygiene should be encouraged minimize environmental contamination and contact with the infectious oocysts that may be shed by dogs.

“…Decreasing age has previously been implicated as an important risk factor for canine giardiosis (Bugg et al, 1999;Capelli et al, 2006;Szénàsi et al, 2007) and is probably related to immunological naivety to the pathogen (Szénàsi et al, 2007). Development of immunological competence may also explain why dogs kennelled for more than 12 months had a lower prevalence of infection.…”

“…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).…”

“…Previous surveys in Germany (Leonhard et al, 2007) and Japan (Itagaki et al, 2005) indicate that the zoonotic genotype A occurred more commonly in domestic dogs than did dog-specific assemblages. However studies in Brazil (Souza et al, 2007) and Hungary (Szénàsi et al, 2007) found only the host-adapted genotypes C and D. In line with the results of a previous study which found 76.5% of G. duodenalis isolates were of assemblage C or D, 19% of assemblage A and 4% of mixed assemblage (Giangaspero et al, 2007), the majority of the isolates in the current study were the dog-specific genotypes C and D. Although this finding suggests that the zoonotic risk from this pathogen is perhaps less significant than previously thought, it must be remembered that 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.…”

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.

“…Among the various methods used, higher infection rates were detected by PCR or enzyme-linked immunosorbent assay (ELISA) than by conventional microcopy. For example, in two studies, the infection rates were 3.3% and 7.5% when micros- copy was used, whereas the rates were 12.9% and 58.8% when ELISA was used (194,251). In another study, the infection rates were 3.0% by microscopy and 20.0% by PCR (265).…”

Zoonotic Potential and Molecular Epidemiology ofGiardiaSpecies and Giardiasis

SUMMARY Molecular diagnostic tools have been used recently in assessing the taxonomy, zoonotic potential, and transmission of Giardia species and giardiasis in humans and animals. The results of these studies have firmly established giardiasis as a zoonotic disease, although host adaptation at the genotype and subtype levels has reduced the likelihood of zoonotic transmission. These studies have also identified variations in the distribution of Giardia duodenalis genotypes among geographic areas and between domestic and wild ruminants and differences in clinical manifestations and outbreak potentials of assemblages A and B. Nevertheless, our efforts in characterizing the molecular epidemiology of giardiasis and the roles of various animals in the transmission of human giardiasis are compromised by the lack of case-control and longitudinal cohort studies and the sampling and testing of humans and animals living in the same community, the frequent occurrence of infections with mixed genotypes and subtypes, and the apparent heterozygosity at some genetic loci for some G. duodenalis genotypes. With the increased usage of multilocus genotyping tools, the development of next-generation subtyping tools, the integration of molecular analysis in epidemiological studies, and an improved understanding of the population genetics of G. duodenalis in humans and animals, we should soon have a better appreciation of the molecular epidemiology of giardiasis, the disease burden of zoonotic transmission, the taxonomy status and virulences of various G. duodenalis genotypes, and the ecology of environmental contamination.
