“…Microorganisms 2021, 9, x FOR PEER REVIEW 2 of 8 E. granulosus s.l. is a species complex and there is ongoing discussion about its speciation [6,7], however, Vuitton et al [8], in agreement with other specialists, recognized five species: E. granulosus sensu stricto (s.s.) (genotypes G1 and G3), E. equinus (G4), E. ortleppi (G5), E. canadensis (G6-G8 and G10) and E. felidis.…”

Cystic echinococcosis (CE) is a zoonosis that is prevalent worldwide. It is considered endemic in Portugal but few studies have been performed on Echinococcus granulosus sensu lato and their hosts. In this study, CE cysts are reported for the first time in a free-living wild boar (Sus scrofa) in Portugal. The presence of the metacestodes in the liver of the wild boar was identified by morphological features, microscopic examination and molecular analysis. The sequencing of part of the DNA nuclear ribosomal internal transcribed spacer-1 (ITS-1) region revealed a G5 genotype that presently corresponds to Echinococcus ortleppi. This is the first report of E. ortleppi in Portugal and to the best of the authors’ knowledge, in Europe. These results suggest that wild boar may be a host of CE, namely, crossing the livestock–wildlife interface, which has important public health implications. Wildlife reservoirs must be taken into account as CE hosts and surveillance of game as well as health education for hunters should be implemented using a One Health approach, with implementation of feasible and tailor-made control strategies, namely, proper elimination of byproducts in the field.

“…The G7 genotype has a wide distribution range including Europe, where the main endemic areas are the Baltic states, Poland and Eastern Europe, whereas elsewhere in Central Europe, Spain (Daniel Mwambete et al ., 2004 ), Italy (Genchi et al ., 2021 ), Portugal (Guerra et al ., 2013 ) and France (Corsica) (Umhang et al ., 2020 ), G7 is distributed predominantly only focally (Deplazes et al ., 2017 ; Casulli et al ., 2022 ). It has also been identified in the Middle East, Mexico and Argentina (Kamenetzky et al ., 2002 ; Villalobos et al ., 2007 ; Borhani et al ., 2021 ), and more recently, in the African Continent, in Namibia (Aschenborn et al ., 2022 ).…”

There are no scientific data available on the occurrence of the Echinococcus granulosus sensu lato (s.l.) cluster in definitive hosts (domestic dogs), intermediate hosts (domestic livestock) nor humans in Cape Verde. In this pilot study, environmental dog fecal samples (n = 369) were collected around food markets, official slaughterhouses, as well as home and small business slaughter spots in 8 of the 9 inhabited islands from the Cape Verde archipelago, between June 2021 and March 2022. Additionally, during the same period, 40 cysts and tissue lesions were opportunistically collected from 5 islands, from locally slaughtered cattle (n = 7), goats (n = 2), sheep (n = 1) and pigs (n = 26). Genetic characterization by a multiplex polymerase chain reaction assay targeting the 12S rRNA gene confirmed the presence of E. granulosus s.l. in fecal and tissue material. In total, 17 cyst samples from Santiago (n = 9), Sal (n = 7) and São Vicente (n = 1) and 8 G6/G7-positive dog fecal samples from Santiago (n = 4) and Sal (n = 4) were identified as E. granulosus s.l. G7 by sequence analysis (nad2, nad5 and nad1 genes). This study discloses the transmission of E. granulosus s.l. G7, in pig, cattle and dog in Cape Verde.
