“…There was only one report of Echinococcus spp. in gray wolves in Turkey, which presented E. equinus and E. canadensis [11]. This study presents E. granulosus s.s. (G1) infection in a gray wolf in Turkey.…”

“…In this study, gray wolf was found to be infected with both E. multilocularis and E. granulosus s.s. with high worm burdens, averaging 49,280 and 62,720 parasites, respectively. Compared to some other studies [8,11,34,35] on wolves infected with E. granulosus s.l., a higher intensity was obtained in this study. In addition, E. multilocularis also had a high intensity in the wolf, similar to red foxes in Erzurum province [28].…”

“…The prevalence of E. multilocularis was 1.3% in France [23], 9.7-35.5% in Slovakia [7], 5.9% in Latvia [24], 3.4% in Mongolia [9], 1% in Iran [21], and 13% in Canada [10]. One case of echinococcosis in gray wolves has been reported in Turkey [11].…”

Objective This study was aimed to confirm the infection and molecular identification of Echinococcus tapeworms in a gray wolf in an urban area of northeastern Turkey. Methods A dead gray wolf (Canis lupus) was found near Erzurum province and brought to the parasitology laboratory. Sedimentation and counting technique (SCT) and polymerase chain reaction (PCR) analysis were conducted. Results The SCT implications indicated that the wolf had a substantial worm burden (62,720 and 49,280 parasites) due to a co-infection of E. granulosus s.l. and E. multilocularis. Genus/species-specific PCR was used to analyze DNA extracted from adult worms and confirmed as E. granulosus s.s. (G1) and E. multilocularis, utilizing COI and 12S rRNA gene sequence analysis, respectively. Conclusion This report presents the first co-detection of E. granulosus s.s. and E. multilocularis in a gray wolf found in an urban area from a highly endemic area for human echinococcosis in northeastern Turkey. The results emphasize that AE is not only a problem of rural areas, but also occurs in urban areas, which may pose a threat to public health. Therefore, surveillance in urban areas is crucial. The need to design new control strategies in domestic and wildlife perspective in the study area is also underlined.

Objective The aim of this study was to identify Echinococcus species by morphological and molecular means. Methods A dead gray wolf (Canis lupus) was found near Erzurum province and brought to the parasitology laboratory. Sedimentation and counting technique (SCT) and polymerase chain reaction (PCR) analysis were conducted. Results The SCT implications indicated that the wolf had a substantial worm burden (62,720 and 49,280 parasites) due to a co-infection of E. granulosus s.l. and E. multilocularis.
