“…Dipylidium caninum (Linnaeus, 1758), a globally distributed cestode, infects domestic cats and dogs [ 8 ], wild canids and felids [ 7 , 10 ], and occasionally humans [ 15 ]. In 1758, Linnaeus recognized the parasite and named it Taenia canina .…”

Analysis of Dipylidium caninum tapeworms from dogs and cats, or their respective fleas

A 28S rDNA PCR detection assay was previously developed to identify Dipylidium caninum DNA inside single fleas collected from both cats and dogs. Sequence analysis of the 28S rDNA fragment indicated two genetically distinct variations of the target region. The two genotypes, so-called “D. caninum canine genotype” and “D. caninum feline genotype”, based on host origin, are further investigated and described in this paper. Restriction fragment length polymorphism (RFLP) analysis and hydrolysis probe-based genotyping assays were developed and validated for genotyping D. caninum DNA. The complete mitochondrial (mt) genome of the “feline genotype” was sequenced and compared to the D. caninum mt genome available in GenBank. The molecular characterization of D. caninum isolates collected from infected fleas, and also proglottids collected from dogs and cats, confirmed the existence of two distinct genotypes. These genotypes are related to host origin (dogs or cats), irrespective of their geographical origin, and they present a biological adaptation to their respective host, as confirmed by the comparison of biological development and host preference in another study. The genetic differences (Part 1, present paper) and biological observations (Part 2, in this journal) enabled us to suggest the existence of two distinct species within D. caninum, which will have to be clarified.

“…Dipylidium caninum sensu lato is an important cestode parasite with a worldwide distribution, as is evident from surveys performed in wild canids and felids, domestic cats, domestic dogs, or concurrent surveys assessing both domestic cats and dogs [ 1 , 3 , 4 , 6 , 8 – 11 , 13 – 19 , 21 , 25 , 26 , 28 , 30 , 32 , 34 – 37 , 40 , 41 , 43 – 48 ]. Apart from infecting both canids and felids, this cestode may also occasionally infect humans [ 2 , 24 , 42 ].…”

Initial investigations suggested the existence of two distinct genotypes of Dipylidium caninum from infected cat fleas (Ctenocephalides felis). One genotype was found almost always (> 95%) in fleas collected from, and proglottids shed by, domestic dogs. The other was found almost always (> 95%) in fleas collected from, and proglottids shed by, domestic cats. Molecular investigations (Part 1, in this journal) confirmed the presence of two distinct genotypes. Due to the apparent host association observed, these were referred to as the “D. caninum canine genotype” and the “D. caninum feline genotype”. The current article reports on an in vivo experimental infection study assessing the host-parasite interaction for each genotype. Mixed infections with the two genotypes in both dogs and cats were conducted. The specific genotyping of proglottids allowed us to assess the specific prepatent periods, prolificity, and longevity of each genotype in dogs versus cats. The possible hybridisation was also studied through molecular evaluation of the proglottids expelled by infected dogs and cats. Results demonstrate a clear distinct host interaction. The canine D. caninum genotype occurred at a higher frequency in dogs, with a shorter prepatent period and a longer lifespan; and the feline genotype occurred at a higher frequency in cats, with a shorter prepatent period and a longer lifespan. The absence of any hybrids in the mixed infections of both dogs and cats confirm the hypothesis of two distinct genotypes, suggesting the possibility of two distinct species within Dipylidium caninum.

“…In 2008, Samkari et al reported one pediatric case and reviewed cases reported in the English-language literature which revealed a total of 34 cases since 1950s [4]. Since that publication, a total of 9 individual pediatric cases have been reported in journals indexed by PubMed, though only 4 are in English language [5][6][7][8][9][10][11][12][13]. An additional case series of 10 pediatric patients were reported in Greece [14].…”

We report a female toddler who presented repetitively with a chief complaint of motile white worms seen in her diapers. Symptoms of perianal itching and visualization of visible motile worms persisted for 6 months despite being treated with multiple courses of albendazole causing a lot of frustration and distress to the caregivers. The characteristics of the worms by inspection along with the presence of 3 pet dogs are consistent with Dipylidium caninum.
