Trichuris suis infection was identified in a pig herd during an investigation into persistent diarrhea and weight loss in 10 recently introduced gilts. Eggs of the parasite were identified in faeces of gilts. Further investigations failed to detect other causes of diarrhea but, in all production stages, they allowed the detection of eggs of Trichuris suis that could explain pasty faeces sometimes observed in weaned sows and frequent diarrhea found in the early fattening period. The administration of levamisole (intramuscular injection) to gilts allowed the excretion of adult parasites, the treatment of diarrhea and the reduction of the number of eggs per gram of faeces. Taking into account the success obtained with levamisole in gilts, the equipment of the farm and the wish of the farmer no to inject finishing pigs, an unsuccessful treatment was tried based on levamisole in drinking water every 8 and then 5 weeks. Flubendazole was finally administrated in drinking water every 3 and then 5 weeks, reducing significantly the number of eggs per gram of faeces. [less ▲]

The present work was carried out in the frame of a Belgian Science Policy project (PONDSCAPE -“Towards a sustainable management of pond diversity at the landscape level”). During the summer 2008, 7103 lymnaeids snails were collected from 125 ponds distributed in 5 clusters of 25 ponds each. Each cluster was located in a different geological region of Belgium. These snails belonged to the following species or genus: 2474 Galba truncatula (the main intermediate host of Fasciola hepatica in Belgium) and 4629 Radix sp. Moreover, several biological (presence of trampling and dungs, snail size …) and non biological factors (pH, depth, fences …) were also registered from the different biotopes. DNA was extracted based on Chelex® technique. Then the snail DNAs were screened through a multiplex PCR that amplifies the lymnaeid internal transcribed spacer 2 sequence (500-600 bp) (acting as an internal control) and a 124 bp Fasciola sp. sequence. Lymnaeid snails were found in 93 biotopes (66%). Thirty Galba truncatula (1.31%) and 7 Radix sp. (0.16%) were found positive for Fasciola sp. A classification and regression tree (CART) analysis was performed in an attempt to better understand the relative importance and relationships among the different recorded factors. For example, the geographic localization is one of the best explanatory variables for the abundance of the different snail species and the presence/absence of faecal material is the best explanatory variable for the presence of specific F. hepatica DNA material in the different screened snails.

Bluetongue, a vector born disease of ruminants, was identified for the first time in Northern Europe in 2006. The vectors are insects of the family Ceratopogonidae, genus Culicoides. In Belgium, no recent data were available about the biology of these insects including their feeding habits and behaviour. The present study was carried out in order to evaluate the indoor and outdoor activity of these Diptera in 5 different cattle or sheep farms in 2008. Two sheep and 3 cattle farms were selected in the Province of Luxembourg, Belgium. In each farm 2 Onderstepoort Veterinary Institute (OVI) traps were installed respectively inside and outside the animal accommodation. Trapping was carried out twice a week from 17:00 until 24:00.The collecting vials were replaced every hour. A portable suction trap (BackTrap® U.S.A) was used twice on each visit to collect midges on the animals. In each farm the study was carried out for 6 successive weeks, 2 farms being monitored together. The study began on July 28th and ended on November 30th 2008. A total of 2591 culicoides were trapped. A majority of those (88.76%) were trapped indoors whereas 10.03% were trapped outdoors and 1.21% directly on the animals. The ambient temperature had a marked effect very few culicoides being trapped below 13°C. Three main species or species complex were identified both indoors and outdoors: C. obsoletus/scoticus, C. dewulfi, C. chiopterus. They represented 98.93% and 85.03% indoors and outdoors respectively. On the animals only C. obsoletus/scoticus and C. dewulfi were found. [less ▲]

An adult neutered male llama (Lama glama) was presented for examination with a history of a severe long lasting (3 years) and recurrent itch and crust formation. Three years ago, scabies had been diagnosed by a local vet on the basis of clinical signs; the animal was treated several times with ivermectin (Ivomec®) injectable and phoxim (Sarnacuran®). After each treatment there was a marked clinical improvement but relapse was the rule within 1 to 2 months. During the two years preceeding our first visit the animal had received local applications of Sarnacuran every two to three weeks wich resulted in incomplete control. None of the owners had reported skin lesions compatible with scabies. On February 27th 2009 the animal showed a marked pruritus accompanied by very thick scabs and alopecia on the face (around the mouth and ears), shoulders, forelegs, hindlegs, abdomen, flanks and the tail. Clinical examination revealed a fairly good general condition. Abnormalities were limited to the skin. Skin scrapings were taken and numerous Sarcoptes scabiei mites were subsequently detected microscopically. Sedation and analgesia were performed via the intramuscular administration of xylazine (Vexylan®) at 0.5 mg/kg. The scabs were humidified with a camomile infusion and a maximum of material was removed and destroyed. Then the llama was treated with 10% moxidectin (Cydectin LA®) at 1 mg/kg by subcutaneous injection at the basis of the ear. On April 6th 2009, a very marked clinical improvement was observed: most of the scabs had dissapeared and hair regrowth in previously alopecic area was observed. Skin scrapings were negative. However, some pruritus was still observed and a second treatment with Cydectin LA was given. According to the owner who was contacted by phone in early May the clinical condition of the animal has further improved. A final visit is planned to assess the clinical and parasitological cure in this S. scabiei infected llama. At our knowledge, this is the first time Cydecin LA is used in llama for the treatment of scabies. [less ▲]

In this review, ten methods used to study digenean infections in their intermediate hosts were compared to determine which one should be used either in the field or in the lab to establish the prevalence and intensity of infections in snails. Snail crushing and snail dissection allow quick establishing of prevalence in natural or experimental infections, whereas histology is considered as the most accurate approach to assess the intensity of infection. The follow-up of cercarial shedding only gave an idea on cercarial production. Among recently developed techniques, polymerase chain reaction (PCR) brings the most accurate information and shows high sensitivity and specificity levels when compared to blotting techniques. The easiness and relatively low cost of the basic PCR protocol make it interesting to investigate the epidemiology of the liver fluke in a lab with limited financial resources. Nevertheless, if this technique allows a relatively good estimation of the prevalence, information concerning the intensity of infection is best obtained through real time PCR. However, at the time being this technique is too expensive to be used routinely in the field. The choice between classical or new techniques is usually based on a compromise, as each technique has its advantages and drawbacks. [less ▲]

A previous study conducted in Belgium revealed that genetic material of Fasciola sp. was present in snail species belonging to the genus Radix. Here, these snails were collected and identified by DNA-based techniques as Radix labiata and Radix balthica. These two species and Galba truncatula (the major intermediate host in Europe) were experimentally infected with Fasciola hepatica. The resulting metacercariae were fed to rats and the infection was monitored using several techniques. Microscopy revealed the presence of larval stages in 78.3, 45, and 6.25% of G. truncatula, R. labiata, and R. balthica snails, respectively. These results were confirmed by a PCR that amplifies a Fasciola sp. specific sequence. Furthermore, this PCR was found to be more sensitive than microscopic examination. R. labiata shed fewer metacercariae than G. truncatula but these were as infective to rats as those shed by G. truncatula. This study demonstrates that R. labiata may act as an incidental intermediate host for F hepatica in Belgium. (C) 2007 Elsevier B.V. All rights reserved. [less ▲]

A previous study in Belgium revealed that genetic material of Fasciola sp. was present in four local snail species: Galba truncatula, Radix peregra, Radix ovata and Lymnaea stagnalis. Laboratory cultures of these four species were experimentally infected with F. hepatica. The collected metacercariae were fed to rats and the infection in that vertebrate hosts was monitored through several techniques. The mortality rates in the breeding unit was less than 10 % in G. truncatula, R. peregra, and L. stagnalis colonies. Microscopy revealed the presence of larval stages in 78.3 % and 48 % of G. truncatula and R. peregra snails, respectively. These data were confirmed by a PCR that amplifies a parasite specific sequence. R. peregra shed fewer metacercariae and more irregularly than G. truncatula. In R. ovata and L. stagnalis the infection rates were low. Specific DNA was detected in both cases by PCR but no metacercariae were shed. The metacercariae shed by R. peregra were as infective to rats as those from G. truncatula. The PCR technique was more sensitive than microscopic examination. This study demonstrated that R. peregra may act as an accidental intermediate host for F. hepatica in Belgium. [less ▲]
