“…in raccoons and raccoon dogs essentially presented identification only at genus level. According to Jesudoss Chelladurai and Brewer [23], the global pooled prevalence rate for raccoons is 17.17% (95% CI: 10.66−24.85%), including studies from Asia (1 study; 531 samples; prevalence 0.2%), Europe (2 studies; 56 samples; prevalence 12.69%) and North America (15 studies; 2358 samples; prevalence 19.97%). In our study, the prevalence of Mesocestoides spp.…”

“…The species of Mesocestoides Valliant, 1863 (Cyclophyllidea: Mesocestoididae) are cestodes that have been noted globally, other than in Australia and Antarctica. Definitive hosts are both wild and domestic terrestrial carnivores (Canidae, Mephitidae, Viverridae, Mustelidae, Procyonidae, Didephidae, Felidae and Hyaenidae), and rarely birds of prey [23]. Mesocestoides spp.…”

“…have zoonotic potential, but records of infections in humans are sporadic [24]. Several species have been described based on morphology in the genus Mesocestoides, but the number of valid species and the use of morphological criteria for species identification have been questioned because of the lack of distinct morphological features, morphological variability within the species, and poorly defined actual host specificity and distribution over wide geographical regions have been noted [23,25,26]. So far, only four representatives of the genus-Mesocestoides litteratus (Batsch, 1786), M. lineatus (Goeze, 1782), M. corti (Hoeppli, 1925) (=M.…”

The raccoon (Procyon lotor) and the raccoon dog (Nyctereutes procyonoides) were introduced to Europe and, in the past decades, their populations have increased and adapted to synanthropic environments across Europe. In view of their possible further spread in Europe, the invasive species should be examined as potential reservoirs for helminths, including tapeworms. This study aims to investigate the prevalence and diversity of tapeworms in introduced wild carnivores in Poland by identifying cestode species based on copro-DNA analysis. A total of 214 individual fecal samples from non-native invasive carnivores, i.e., raccoons and raccoon dogs, and additionally 47 samples from native carnivores, i.e., European badgers (Meles meles), were analyzed for the presence of cestodes. PCR analysis of fecal samples targeting a fragment of mitochondrial (mt) 12S rRNA gene revealed the presence of cestode DNA in 19 of 103 (18.4%) raccoons, in 13 of 111 (11.7%) raccoon dogs and in 23 of 47 (48.9%) badgers. Sequence analysis demonstrated the presence of Mesocestoides litteratus in raccoons and raccoon dogs, while Mesocestoides lineatus was identified only in two samples derived from raccoon dogs. Moreover, in this study, Atriotaenia incisa was for the first time molecularly characterized by using fragments of mt 12S rRNA gene, and the DNA of this cestode species was detected in the fecal samples of all the examined host species.

“…Genus Mesocestoides is controversial mainly because its systematics and life cycles are not completely understood (Jesudoss Chelladurai & Brewer 2021). It is presumed to have a three-host life cycle, with carnivorous vertebrates, mostly mammals, as definitive hosts; meanwhile, coprophagous insects would act as first intermediate hosts, and small vertebrates, preying on these arthropods, as second intermediate hosts (Padgett et al 2005).…”

“…However, recently McAllister et al (2018) suggested that there is a two-host life cycle based on the finding of pre-tetrathyridial larvae in the coelomic cavity of a ground skink ( Scincella lateralis ). Albeit there are myriad species recorded as intermediate hosts of Mesocestoides spp., its prevalence is frequently low (~7%) (Bursey et al 2012; Jesudoss Chelladurai & Brewer 2021). Moreover, this tapeworm has been recorded in domestic dogs and cats as definitive hosts, and as accidental hosts harboring tetrathyridia in the peritoneal cavity, causing the so-called peritoneal larval cestodiasis, which could lead to a fatal outcome (Jesudoss Chelladurai & Brewer 2021).…”

Tetrathyridia in an endemic lizard from Chile: molecular evidence for South America

et al. 2023

Mesocestoides is a controversial tapeworm with significant lack of data related to systematics and life cycles. This helminth has an indirect life cycle with vertebrates, mostly carnivorous mammals, as definitive hosts. Theoretically, a coprophagous arthropod would be the first intermediate host, and herptiles, mammals, and birds, which prey on these insects, would represent the second intermediate hosts. However, recent evidence suggests that this life cycle would require only two hosts, with no arthropods involved. In the Neotropics, although there are records of mammals and reptiles as hosts for Mescocestoides, no molecular analyses have been performed. This work aimed to record an additional intermediate host and molecularly characterize the isolated larvae. Thus, 18 braided tree iguanas (Liolaemus platei) from Northern Chile were collected and dissected during 2019. One lizard was parasitized by three morphotypes of larvae compatible with tetrathyridia of Mescocestoides. To achieve its specific identity, a molecular approach was performed: 18S rRNA and 12S rRNA loci were amplified through cPCR. The inferred phylogenies confirmed the morphological diagnosis and stated that all morphotypes were conspecifics. The sequences for both loci formed a monophyletic clade with high nodal support, representing a sister taxon to Mescocestoides clade C. This study represents the first molecular characterization of any taxon of Mescocestoides from the Neotropics. Future surveys from potential definitive hosts would help to elucidate its life cycle. Furthermore, an integrative taxonomic approach is required in additional studies from the Neotropical region, which would contribute to a better understanding of the evolutionary relationships of this genus.
