“…The same authors examined 102 birds from Czechia, among which 23 individuals were infected with bird schistosomes, including 14 birds infected with B. polonica (Rudolfová et al, 2007). The latest research of final hosts presented by Lashaki et al (2020) indicates that Allobilharzia visceralis and Trichobilharzia spp. had the highest frequency in the world.…”

Bird schistosomes are commonly established as the causative agent of swimmer's itch − a hyper-sensitive skin reaction to the penetration of their infective larvae. The aim of the present study was to investigate the prevalence of the genus Bilharziella in comparison to other bird schistosome species from Lake Drawsko − one of the largest recreational lakes in Poland, struggling with the huge problem of swimmer's itch. In total, 317 specimens of pulmonate snails were collected and examined. The overall digenean infection was 35.33%. The highest bird schistosome prevalence was observed for Bilharziella sp. (4.63%) in Planorbarius corneus, followed by Trichobilharzia szidati (3.23%) in Lymnaea stagnalis and Trichobilharzia sp. (1.3%) in Stagnicola palustris. The location of Bilharziella sp. on the presented phylogeny showed that it is with high probability a different species than known so far B. polonica. Our finding complements the confirmed occurrence of bird schistosomes in European water bodies. Overall, presented research reveals the special importance of P. corneus as a source of the bird schistosome cercariae. This study suggests that the health threat connected with the blood flukes need to be further investigated by constant monitoring of their occurrence in intermediate hosts.

“…It should be stressed that Swimmer’s itch is considered an emerging disease in various parts of the world, resulting in various nervous or pulmonary symptoms on the basis of the infecting species [ 38 ]. Furthermore, avian schistosomes have been considered the most neglected parasitic zoonosis among aquatic birds worldwide [ 23 ]. To the best of our knowledge, there are no published studies describing the pathological effects of schistosome infection in whooper swans in Japan.…”

“…In humans, the repeated penetration of the skin causes the human cercarial dermatitis (HCD), an allergic reaction also known as “swimmer’s itch” [ 1 , 15 , 22 ]. Cercarial dermatitis can be caused by several species of avian schistosomes, e.g., those belonging to the genera Trichobilharzia , Gigantobilharzia , and Austrobilharzia [ 3 , 8 , 10 , 11 , 23 ]. The zoonotic potential of other species, such as the swan schistosome Allobilharzia visceralis remains unknown [ 6 , 24 , 25 ], despite it cannot be excluded that it can produce HCD.…”

“…In many cases, an etiological diagnosis of HCD at species level can be difficult to achieve, and it cannot be excluded that some cases could be due to A. visceralis . Swans are present in Japan and can transport their schistosomes during their migrations [ 15 , 23 , 27 ]. Indeed, A. visceralis has been already reported in swans either in Japan other than in North America and Iceland [ 13 , 28 , 29 , 30 ].…”

Cercarial dermatitis, or Swimmer’s itch, is one of the emerging diseases caused by the cercariae of water-borne schistosomes, mainly Trichobilharzia spp. Since the zoonotic potential of Allobilharzia visceralis is still unknown, studies on this schistosome would be helpful to add knowledge on its possible role in causing human infections. In the present study, 54 whooper swans (Cygnus cygnus) from rescue/rehabilitation centers in Honshu, Japan, were necropsied to identify the cause of death. Grossly, 33 (61.11%) swans were severely emaciated and 23 (42.59%) had multiple reddened areas throughout the length of the intestine with no worms detected in the internal organs. Microscopically, adult schistosomes were found in the lumen of the mesenteric, serosal, portal, and testicular veins, in the capillaries of the intestinal lamina propria, and in the sinusoids of the adrenal gland, spleen, and liver of 23 (42.59%) swans. Hypertrophy of veins containing adult worms was identified in 15 (27.77%) swans, and vascular lumen obliteration was observed in 8 (14.81%) swans. Mild to severe villous atrophy and superficial enteritis were observed in 8 birds (14.81%), whereas bile pigments and hemosiderin were detected in the livers of 14 (25.92%) and 18 (33.33%) swans, respectively. In three swans (5.55%), schistosome parasites were found in the subcapsular veins of the testes. The schistosomes in the present study were assumed to be A. visceralis based on the microscopical and histological evidence of adult schistosomes found in the lumen of veins as well as the infection pathology, which was very similar to the schistosome-induced pathology previously reported in swans infected by A. visceralis in Europe and Australia. The swans examined herein most likely died from obstructive phlebitis associated with A. visceralis, but further molecular confirmation is required for identification of this species. However, the present study does not provide new data on the zoonotic potential, but only on the pathogenic potential of this schistosome in swans. Furthermore, our study provides a novel contribution to the description of the pathological effects of avian schistosomes infection in whooper swans in Japan.

“…Study on avian schistosomes is very important not only from a veterinary perspective but also as a means of predicting the hazard of human infection by the schistosome cercariae ( Picot et al, 1996 ; Lashaki et al, 2020 ; Żbikowska, 2002 ). This infection known as human cercarial dermatitis (HCD), regarded as a re-emerging infectious disease in human ( Kolářová et al, 2013 ).…”

Background Avian schistosomes are considered as main causative agents of human cercarial dermatitis (HCD) in Iran. The study was conducted to determine bird schistosomes in their final and intermediate hosts, in main wetlands of Mazandaran. Methods A total of 255 domestic and wild ducks were collected and the infection of nasal tissues of five ( Anas platyrhynchos domesticus , Aythya ferina, Cairina moschata, Anas platyrhynchos and Spatula clypeata ) species were analyzed using morphological techniques. Also, 1687 freshwater snails were collected and surveyed by cercarial shedding and crushing tests. Detection of HCD was performed for the presence of clinical symptoms of itching and maculopapular rashs by physical examination. Results Of 255 ducks, in 41 (16%) infection with nasal Trichibilarizia spp. were recognized by observing eggs and/or adult worms. The most infected ducks were Anas clypeata and Anas platyrhynchos domesticus . Overall, 0.17% of snails were infected with avian schistosomes. Also, clinical examination of 951 rice farmers revealed that 588 (61.82%) of them were suffered from HCD. Conclusion Our data suggest that domestic ducks could play a prominent role as a reservoir host for establishing life cycle of Trichobilharzia in the area. Also, existence of domestic reservoir ducks and suitable snail hosts in ponds and paddy fields of this area, climate conditions of the wetlands in Mazandaran leads to a high incidence of HCD.
