BACKGROUND: Besnoitiosis is caused by different species of intracellular protozoan parasites belonging to the family Sarcocystidae and affecting multiple host species worldwide. Including B. besnoiti, ten species are described infecting animals. Among ungulates, Besnoitia bennetti infects horses, donkeys and zebras and was described in Africa and in the USA where donkey besnoitiosis is considered as an emerging disease. CASE PRESENTATION: A two-year-old male donkey was purchased in May 2016 in poor body condition (cachexia, alopetic areas and pruritus mainly on neck and head) by the present owner in Le Roeulx (Belgium) from a milk producing donkey farm in Frasnes-lez-Buissenal (Belgium). Shortly after its purchase and shearing, the donkey presented with crusts, hyperkeratosis (both flanks and neck) anorexia and cachexia. A treatment with phoxim was given with no improvement. A cutaneous biopsy of hyperkeratotic skin was performed in July. It showed a perivascular eosinophilic infiltrate with a large thick walled cyst located in the dermis containing numerous bradyzoites. This was highly suggestive of besnoitiosis. Several skin biopsy samples were obtained for qPCR analysis and confirmed the presence of Besnoitia spp. DNA. Further laboratory diagnosis tests were performed (western blot and rDNA sequencing) confirming Besnoitia bennetti aetiology for the male. For the female, the punch-biopsy, haematology and qPCR were negatives but the western blot showed the presence of antibodies directed to Besnoitia spp. Further clinical examination performed in August highlighted scleral pinhead sized cysts (pearl) in the right eye and between nares. Another ten-year-old female donkey purchased in France and sharing the same accommodation showed a good clinical condition, but a thorough clinical examination showed the presence of numerous cysts on the inner face of upper labial mucosa. A daily treatment based on sulfamethaxzole and trimethoprim (Emdotrim 60% Mix(R), 30 mg/kg) was given orally and some improvement was noticed. CONCLUSION: This is the first evidence of Besnoitia bennetti infection (Protozoa: Apicomplexa) in donkeys (Equus asinus) in Belgium. [less ▲]

A cranial abdominal mass on the left side was detected upon palpation in a two-and-a-half-year-old male wirehaired dachshund. No other clinical signs were recorded except exhaustion following exertion, and soft faeces. Abdominal echography showed hepatomegaly with extensive histological alterations; microscopical examination of smears from hepatic mass and fluid punction revealed a low cellularity and protoscolex-like structures. Following those findings, euthanasia was requested by the owner. Necropsy revealed a severe multifocal chronic active hepatitis with some degree of right ventricular dilatation. Based on histopathology and PCR, a diagnosis of alveolar echinococcosis due to Echinococcus multilocularis was established. The dog was living in the Ardennes region in Belgium known as being endemic for E multilocularis. The present observation is in agreement with a similar canine case previously published and the high prevalence of E multilocularis in the local fox population. © British Veterinary Association.

BACKGROUND: Cercarial dermatitis or swimmer's itch is a skin condition in humans due to the larval forms of bird schistosomes of some species of the genus Trichobilharzia. The life cycle of these schistosomes requires freshwater snails (intermediate host) and waterfowl (definitive host). Repeated exposures to cercariae can lead to skin sensitization with the induction of pruritic skin lesions. METHODS: We describe, in this study, two outbreaks of human cercarial dermatitis at the Eau d'Heure Lakes, Belgium. In July and August 2012, a total of, respectively, 78 and 10 people reported a sudden skin rash accompanied by pruritus following recreational activities in the Plate Taille Lake. However, no ocellate furcocercariae were detected following light exposure of the snails collected between September 2012 and September 2013 (n = 402). No outbreaks were recorded in 2013 and 2014. In August 2015, about 30 new cases were recorded. Snails were collected (n = 270) in different locations around the lake. PCR was used to identify accurately the intermediate hosts and the parasite species involved. RESULTS: After light exposure, seven Radix spp. (2.6%) shed ocellate furcocercariae. Molecular identification based on the rDNA internal transcribed spacer 2 sequence ascribed the infected snails to R. balthica ( = R. peregra = R. ovata) (6/7) and R. auricularia (1/7). Based on the amplification of the D2 domain of the 28S rDNA, the cercariae were shown to belong to two different haplotypes of Trichobilharzia franki. CONCLUSIONS: This is the first record in Belgium of T. franki and associated skin condition. [less ▲]

Eight cases of sarcoptic mange in foxes were reported during summer 2014 (n=3) and winter 2015 (n= 5) in Belgium. All animals came from the same restricted forest zones near urbanized areas and some of them were discovered in private gardens (Forest District of Thuin, Hainaut, Belgium). Three of them were found dead, the others were shot for sanitary reasons. At necropsy, all of them presented large areas of alopecia and extensive skin lesions such as hyperkeratosis and suppurative lacerations. Animals presented poor body condition and some of them were severely emaciated (absence of visceral fat). Mange has profound influences on population since, if untreated, death follows in four to six months. In the present cases, cutaneous scrapings and histopathological examinations were systematically performed. Numerous parasites were observed in skin scrapings and marked dermo-epidermatitis with several parasites was observed in histopathological sections. These results suggest an outbreak of sarcoptic mange in red foxes in a limited area of the country. This is a first record for the country. Furthermore, investigations on lungs and digestive tracts performed on 3 of these foxes revealed they were also infected by parasites transmissible to pets and/or humans: Angiostrongylus vasorum was observed in the respiratory tract of one fox whereas Toxocara canis, Uncinaria stenocephala, Taenia spp. and Echinococcus multilocularis worms were detected in the digestive tract. In conclusion, urban foxes represent a source of parasites of public health and veterinary importance and foxes surveillance should be strengthened in these areas. [less ▲]

Fasciolosis is a zoonotic disease of ruminants and other herbivorous due to two parasite species of the genus Fasciola. If Fasciola gigantica is a tropical species, F. hepatica has a much wider geographic distribution. Fasciola hepatica is responsible for important economic losses such as a marked reduction of milk yield and liver condemnation at the slaughterhouse. The life cycle of this platyhelminth involves an intermediate host, a gastropod mollusc belonging to the Lymnaeidae family. In temperate Europe, Galba truncatula acts as the main intermediate host of F. hepatica. A wide network project called MANSCAPE allowed the implementation of a sampling campaign conducted in more than 125 ponds throughout Belgium which revealed that other lymnaeid snails (belonging to the genus Radix) could act as secondary or alternative intermediate hosts. Some experimental infections of snails and rats permited to study the host-parasite relationships in some of these species (Radix balthica, R. labiata). Sibling species very similar to « R. peregra » seem to contain several potential candidates. Several techniques are available to detect the parasite in the snail: they are based either on microscopy or on molecular biology. A very sensitive (100 pg parasite DNA still detectable) and specific technique based on molecular biology (Multiplex PCR) was developed. This technique was used qualitatively and quantitatively to determine the intermediate host species involved in the life cycle of the liver fluke in Belgium. This study was performed in the frame of the PONDSCAPE project and prevalences of 1.31% (30/2747) and 0.16% (7/4629) were recorded for G. truncatula and R. balthica respectively. This technique was then used in Ecuador to bring some information on the intermediate host species involved in the life cycle of F. hepatica. Galba schirazensis, an invasive species in South America, was identified as a lymnaeid that could harbour a part of the life cycle of the parasite as 8.15% (86/1055) of the collected snail contained parasite DNA and 2.46% (26/1055) living larvae. These studies showed that R. balthica could have an impact on the epidemiology of F. hepatica in Belgium and that the role of G. schirazensis in Ecuador needs to be clarified. This will be discussed in this work and specially in term of co-evoultion and adpatation way. [less ▲]

Fasciolosis is a widely distributed disease in livestock in South America but knowledge about the epidemiology and the intermediate hosts are scarce in Ecuador. During 3 months, lymnaeid snails were sampled (n=1482) in Pichincha province in two sites located in a highly endemic area. The snails were identified (based on morphology and ITS2 sequences) and the infection status was established through microscopic dissection and a multiplex PCR-based technique. If morphologic-based techniques were not useful to accurately named the one species collected, alignment study ascribed it to L. schirazensis. Rediae were observed in 1.75 % (26/1482) and Fasciola sp. DNA was detected in 6% (89/1482) of the collected snails. The COX1 region permitted the parasite species identification: F. hepatica. The relative sensitivity and specificity of the microscope related to the PCR results was 25.84% and 99.78% respectively. The mean size of the snails recorded positive for F. hepatica through crushing and microscopy was significantly higher than the mean size of negative snails. There was not such difference in PCR positive snails. The role of G. schirazensis as an intermediate host of F. hepatica in Ecuador is discussed and a hypothesis of an adaptation of the snail to the trematoda is formulated. For the first time, an epidemiological survey, based on molecular biology-based techniques assessed the role of lymnaeid snail in the epidemiology of fasciolosis in Ecuador. [less ▲]

Trichuris suis, also called whipworm, is a parasite of the caecum and colon distributed widely and considered as a fairly common parasite in swine. It may be responsible for porcine trichurosis characterized by diarrhoea, anorexia, growth retardation, dehydration, emaciation and anaemia. This report presents a case of trichurosis diagnosed in a farrow-to-finish Belgian pig herd. The infection was associated with severe and persistent diarrhoea, growth retardation, emaciation and/or anaemia in 10 recently purchased gilts and in fattening pigs. In gilts, levamisole [8 mg/kg body weight] administered once per os gave a good clinical response, as diarrhoea resolved in nine gilts out of 10. In parallel, for these nine gilts, the number of eggs of T. suis/g faeces passed decreased from 12 400 to less than 100 eggs. In fattening pigs, flubendazole (1 mg/kg BW) administrated over 5 days in drinking water allowed a reduction in the number of T. suis eggs/g and was effective against diarrhoea. Although most of the time pig whipworm infections are light and asymptomatic, in some cases when large numbers of worms are present, they can cause watery to bloody diarrhoea that can lead to anaemia. This less frequent disease should not be forgotten in the differential diagnosis of persistent diarrhoea in growing pigs. [less ▲]

Freshwater snails of the family Lymnaeidae play an important role in the transmission of fascioliasis worldwide. In Vietnam, 2 common lymnaeid species, Lymnaea swinhoei and Lymnaea viridis, can be recognized on the basis of morphology, and a third species, Lymnaea sp., is known to exist. Recent studies have raised controversy about their role in transmission of Fasciola spp. because of confusion in identification of the snail hosts. The aim of this study is, therefore, to clarify the identities of lymnaeid snails in Vietnam by a combination of morphological and molecular approaches. The molecular analyses using the second internal transcribed spacer (ITS2) of the nuclear ribosomal DNA clearly showed that lymnaeids in Vietnam include 3 species, Austropeplea viridis (morphologically identified as L. viridis), Radix auricularia (morphologically identified as L. swinhoei) and Radix rubiginosa (morphologically identified as Lymnaea sp.). R. rubiginosa is a new record for Vietnam. Among them, only A. viridis was found to be infected with Fasciola spp. These results provide a new insight into lymnaeid snails in Vietnam. Identification of lymnaeid snails in Vietnam and their role in the liver fluke transmission should be further investigated. [less ▲]

This study aimed to identify tick species and to determine their relationship with the Theileria parva seroprevalence in cattle raised under an extensive farming system in North Kivu Province, Democratic Republic of Congo in two agro-ecological zones namely medium (1,000-1,850 m) and high (>1,850 m) altitude. Among the 3,215 ticks collected on 482 animals, from February to April 2009, Rhipicephalus appendiculatus (64.26 %), the main vector of T. parva, was the most abundant species followed by Rhipicephalus decoloratus (35.49 %) and Amblyomma variegatum (0.25 %). The mean burden of R. appendiculatus tick per infested animal appeared significantly higher at medium (6.5 +/- 0.22 ticks) than at high (0.07 +/- 0.3 ticks) altitude (P < 0.05). However, an indirect fluorescent antibody test carried out on 450 blood samples revealed a global T. parva seroprevalence of 43 % (95 % CI: 38-47) which was not significantly (P > 0.05) different between medium (48.4 %; 95 % CI: 38-49) and high (41.9 %; 95 % CI: 35-49) altitude. These relatively low seroprevalences suggest that there is a state of endemicity to T. parva infection in the study area. The presence of the tick vector on animals was associated with an increased risk of being seropositive to T. parva infection (odds ratio = 2.04; 95 % CI: 1.8-2.3; P < 0.001). The results suggest the need for a longitudinal study to investigate the seasonal dynamics of tick species and T. parva infection. The rate of tick infection should also be evaluated in order to determine the intensity of T. parva transmission to cattle. [less ▲]
