The aim of our study was to determine the level of parasitic infections in European bison (Bison bonasus) in the Bieszczady Mountains on the basis of coprological methods: flotation, decantation and the Baermann technique. 429 faecal samples were collected from European bison in the following Forest Districts: Baligród, Komańcza, Lutowiska, Stuposiany, Lesko and Cisna. Examination of faeces revealed the presence of eggs of gastrointestinal nematodes from the Trichostrongylidae family, as well as Nematodirus sp., Aonchotheca sp. and Trichuris sp., larvae of lung nematodes Dictyocaulus viviparus, eggs of tapeworms Moniezia sp. and oocysts of 7 species of coccidia, belonging to the genus Eimeria (E. bovis, E. zuernii, E. pellita, E. bukidnonensis, E. subspherica, E. ellipsoidalis and E. brasiliensis). The population of European bison in the Bieszczady Mountains turned out to be the only free-living herd not infected with the liver fluke Fasciola hepatica. The level of parasitic infections, observed during present study, was low and did not indicate clinical signs of parasitic disease, thus it did not require deworming.

This study was conducted in order to determine the presence of parasitic infections of the Greek buffalo (Bubalus bubalis) in the Prefecture of Serres, Northern Greece. During the period from February to October 2014, faecal samples from 110 buffaloes of the Greek buffalo breed (Bubalus bubalis), from 9 farms located in proximity to Lake Kerkini, in the Prefecture of Serres, Northern Greece, were examined, in order to find reproductive elements of parasites. Out of 110 faecal samples examined, 102 (92.73%) were found infected with reproductive elements (eggs, larvae, cysts and oocysts) of parasites. Specifically, the parasites found were: Eimeria spp. (40%), Entamoeba bovis (16.36%), Paramphistomum cervi (10%), Fasciola hepatica (16.36%), Dicrocoelium dendriticum (28.18%), Moniezia benedeni (27.27%), Toxocara vitulorum (11.82%), Strongylida (gastrointestinal nematodes) (31.82%) and lungworms (28.18%). The present study appears to be the first report of the detection of lungworms in buffaloes, in Greece.

Beef Suckler

Endoparasites are one of the major health issues in beef suckler cows and can cause economic losses. As studies on the parasitological status of beef suckler cow herds are rare, the aim of this study was to evaluate the status quo of the parasite burden in herds at four representative locations in Germany. Additionally, the farmers’ pasture management and deworming strategies were documented. Based on these data, the second aim of the study was to develop recommendations for improved deworming and pasture hygiene management. A total of 708 faecal samples were examined with parasitological routine methods. Results revealed Fasciola hepatica, gastrointestinal nematodes (GIN), Eimeria species (spp.), Moniezia spp. and Dictyocaulus viviparus as the most frequent findings. Clinical signs of parasitic diseases were not found during the farm visits. Statistical analyses showed a significant effect of the age status of the animal on the parasitological status in general. Due to the percentage of occurrence, detailed statistical analysis was performed for Eimeria, GIN and Fasciola hepatica, confirming the effect of age status. Assessing the parasitological status of beef suckler cows as routine procedure could help to establish an improved parasite-control management on a farm-individual basis.

Abstract Helminth and protozoan infections are responsible for important diseases in grazing sheep, which can be especially threatening in an autochthonous breed at risk of extinction like the Churra Galega Mirandesa Portuguese sheep breed. The aim of the present study was to determine the diversity, prevalence and burden of gastrointestinal parasites in these sheep and to assess the effects of deworming practices, cohabiting animals on the farm and feed management. Coprological qualitative and quantitative analysis (flotation, natural sedimentation and McMaster method) were used to identify and quantify gastrointestinal parasites and a questionnaire was designed and applied. A total of 512 faecal samples were collected from 49 flocks, and 49 replies to the questionnaire were received. Parasites were identified in 100% of the flocks, and in 97% of the samples. The genera or species that have been morphologically identified were: strongyle-type, Nematodirus spp., Skrjabinema spp., Moniezia expansa, Moniezia benedeni, Trichuris spp., Capillaria spp., Eimeria spp., Dicrocoelium spp. and Fasciola hepatica. This is the first report in Portugal of Skrjabinema spp. The burden of parasites’ oocysts and eggs per gram in faecal samples ranged, respectively, from 50 to 17,550 for Eimeria spp., and from 50 to 6250 for strongyle-type eggs. Factors affecting parasitic infections were evaluated using a multivariate logistic regression. Grazing time and a lack of anthelmintic treatment were positively associated with Nematodirus spp. infection. This study showed that there is a high prevalence and diversity of gastrointestinal parasites in the Churra Galega Mirandesa sheep breed.

Abstract Background Pasture management influences the prevalence and impact of the pasture parasites (PP) in cattle herds, which cause production-limiting disease worldwide. Evaluating farmer management strategies is vital when considering sustainable PP control practices. The aim of this questionnaire-based study was to describe the pasture management and control strategies regarding PP in Norwegian beef cattle (BC) and dairy cattle (DC) production systems with a focus on gastrointestinal nematodes (GIN) and Fasciola hepatica. Results A total of 745 responses from BC (return rate 20.5%) and 1347 responses from DC farmers (30.7%) were included. The mean total pasture time for DC was 4.2 months for first-season grazers and 4.3 months for second-season grazers and cows, while the corresponding finding in BC was 5.4 months. Home pasture was used for most of the pasture period, particularly for first-season grazer dairy heifers (81%), which were also commonly grazed on the same pasture every year (79%). For most farmers it was necessary for grazing areas to be used for cattle for more than one season (77% of BC farmers and 89% of DC farmers). However, changing the pasture during the season was common in both DC (67%) and BC (70%) herds. The majority of DC farmers (60%) stated that they did not consider that they had a problem with PP. Of the remaining 40%, few respondents could specify whether their herds had a problem due to infection by GIN (11%) or liver flukes (12%). Treatment for GIN was performed by 52% of DC and 34% of BC farmers. Diagnostic faecal samples were collected upon suspicion of parasitic disease by 5% of DC and 16% of BC farmers. Veterinarians were stated as a central source of information about parasite management and treatment. Conclusions Potential risks for exposure to PP were identified, such as use of the same pasture every year for first-season grazers and frequent use of home pasture. The perception of problems related to PP appeared low. Regular anthelmintic treatment without concurrent use of diagnostic faecal samples seems to be common practice.

Abstract. Prevalence of gastrointestinal parasites was studied in 106 heifers imported to Poland from the Netherlands. Prevalence of gastrointestinal nematodes and Eimeria protozoans was determined from coproscopic examinations using Willis-Schlaf flotation. The species composition of coccidia was determined from morphological characters and the time of oocyst sporulation. Fluke liver eggs were detected by decantation. The study showed the mean prevalence of Eimeria protozoans in the heifers imported from the Netherlands to Poland to be 17.92 %; the mean prevalences of Cryptosporidium sp. (11.32 %), gastrointestinal nematodes (55.66 %) and Fasciola hepatica (32.08 %), respectively. The following 6 coccidia species were isolated from faecal samples: E. bovis, E. aubernensis, E. ellipsoidalis, E. subspherica, E. zürni, and E. brasiliensis. The prevalence of gastrointestinal parasites in the cattle imported from the Netherlands to Poland was very high, therefore it is purposeful to mandatorily examine the imported cattle for the presence of those parasites.

Pasture Contamination

Small ruminants in northwestern Spain are frequently managed in mixed flocks. Sheep–goat joint management has not been considered a risk factor for parasite infection, so the main objective of this study was to establish if mixed management with goats supposes a risk factor for parasitic infections in ovine flocks. Two thousand and ninety-three sheep were sampled from 74 commercial meat ovine flocks for diagnostic of the main parasites. Goat contact was a risk factor for sheep to be infected by protostrongylids, Dictyocaulus filaria, gastrointestinal nematodes and Eimeria spp. In contrast, Moniezia, Fasciola hepatica, Dicrocoelium dendriticum and Paramphistomidae prevalences were not influenced. Sheep–goat mixed management can be considered as a risk factor, since goats would act as a source of pasture contamination for interspecific parasites (protostrongylids, Dictyocaulus filaria and gastrointestinal nematodes). In relation to host-specific parasites, such as Eimeria spp., goats cannot be considered as a source for sheep, but competition for food and spaces between both small ungulates can suppose a reduced grazing area to sheep, provoking high environmental contamination and stress that facilitate their infection. Future epidemiological studies for parasitic infections in small ruminants should consider sheep–goat mixed management as a possible risk factor to be included in multivariate analyses.

AbstractIntroductionCommon parasites of the European bison include gastro-intestinal and pulmonary nematodes, liver flukes (Fasciola hepatica), tapeworms, and protozoa of the genus Coccidia. This study compared the extensiveness and intensities of European bison parasitic invasions in three north-eastern Polish forests in different seasons and queried the role of parasitological monitoring in sanitary and hygienic control of feeding places.Material and MethodsFaecal samples were collected in the Białowieża, Knyszyńska, and Borecka Forests between 2014 and 2016, as were some from an area neighbouring the Białowieża Forest outside the Natura 2000 protected area. Parasites were detected in individual samples with the flotation, decanting and Baermann methods.ResultsThe eggs of Trichostrongylidae, Aonchotheca sp., Nematodirus sp., Strongyloides spp., Trichuris sp., Moniezia spp., and Fasciola hepatica; the larvae of Dictyocaulus viviparus; and the oocytes of Eimeria spp. were identified. Significant variation in invasion intensity and diversity was seen by origin and season. The relationships were assessed first by univariable tests and next multivariately, when origin and season emerged as the major risk factors for exposure to most of the parasites.ConclusionThe differences in the level of parasitic infection between the forests did not have implications for its sufficiency to cause clinical symptoms. However, the associations and risk factors found enable the necessary preventive measures to be taken to protect the E. bison from exposure or decrease the risks. Additionally, parasitological monitoring is appropriate as the method of sanitary and hygienic control of European bison winter feeding places. Threats to public health through adventitious invasions by zoonotic factors such as F. hepatica have been identified.

Sick and dead 2-months-old partridges (Alectoris chukar) were presented to the unit of Avian Medicine, Faculty of Veterinary Medicine, Aristotle University of Thessaloniki, Greece. The birds were reared at a specially constructed wire cage, which covered 600 m2 of the ground, including self-growing flora, in the region of Diavata, in the countryside of Thessaloniki. The farm consisted of young partridges, adult pheasants and wild passerines. Two months after placing the birds, 5 partridges were found dead. During the clinical examination of the submitted sick partridges, severe respiratory distress was observed, while some birds had anemic combs and others were breathing with open beaks and had their necks stretched. The necropsy revealed the presence of numerous gapeworms in the lumen of the trachea, forming the typical " Y" shape, since male and female Syngamus trachea are locked in copulation. The mucosa of trachea was, also, thickened, irritated and congested. No lesions to other organs were observed and the microbiological examination of liver, spleen and air-sacs samples was negative. Meanwhile, faecal samples were collected from the farm for parasitological examination. A sedimentation method was used and eggs of S. trachea were found. Syngamosis was determined to be the cause of the partridges' death. The gapeworms are considered potentially dangerous, especially for backyard, game-birds and free-living birds, while the control of the disease is complicated. This fact, along with the selective appearance of the clinical signs and the mortality only in the partridges of the farm are the remarkable points discussed in this article.

Reliable Diagnostic Method

The sensitivity and utility of a standard faecal sedimentation method (FSM) and a modified stool sieving staining method (FSSM), both currently employed for the diagnosis of Fasciola hepatica infection were compared. Faecal samples were obtained from 51 bovines of an endemic area for fasciolosis in Southwestern Argentina. Each sample was placed in a recipient containing 5% formalin. Eight millilitres of the suspension, equivalent to 2g of faeces, were used for each of the two methods tested. The number of eggs found per sample was recorded. The proportion of positive samples obtained by the FSSM (27/51) was significantly higher than that by the FSM (11/51) (P<0.05). The percent of agreement between methods was 41%. Over a total of 27 positive samples detected by the FSSM, the FSM missed 16, yielding 60% false negative samples. The FSSM enhanced 2.5 times the sensitivity of diagnosis. The complexity of the FSM may decrease its sensitivity through missing and loss of eggs during sample processing. These results confirmed that the commonly used FSM underestimates the prevalence and the egg output in cattle and that the FSSM is a more reliable diagnostic method.
