    Abstract Anthelmintic resistance (AR) of small strongyle populations (cyathostomins) against products of the benzimidazole and tetrahydropyrimidine classes occurs now worldwide and there is an increasing number of reports also regarding macrocyclic lactones. Consequently, and in order to maintain an appropriate horse parasite control, alternative control schemes must be evaluated under field conditions. Here we present a six-year field study on the administration of the so-called selective or targeted selective anthelmintic treatment (SAT) concept. In this study on five horse farms in France and Switzerland, 757 fecal samples from 93 equids (90 horses, 3 ponies) have been taken twice a year (between early and late spring and between early and late autumn) from autumn 2014 to spring 2020 and processed by a McMaster technique. From a total of 757 samples, only 263 (34.7%) had a fecal egg count ≥200 EpG and needed an anthelmintic treatment. This small number of fecal samples ≥200 EpG demonstrates the considerable potential for a long-term reduction of the number of anthelmintic treatments and the anthelmintic pressure by using the SAT-programme.

    Abstract The hard tick Dermacentor reticulatus transmits Babesia canis , the causative agent of canine babesiosis. Both the occurrence and local distribution of D. reticulatus as well as infection rates of questing ticks with B. canis are thus far poorly known in Bavaria, Germany. The objectives of this study were to conduct (1) a georeferenced field study on the occurrence of D. reticulatus with digital habitat characterization and (2) a PCR analysis of D. reticulatus collected in Bavaria for infection with B. canis . Dermacentor reticulatus were collected by flagging at 60 sites specifically selected according to habitat conditions and screened individually for Babesia DNA. A digital habitat characterization for D. reticulatus was performed according to results of the field analysis including the parameters land use, proximity to water, “potential natural vegetation”, red deer corridors and climate data. Altogether, 339 D. reticulatus ticks (214 females and 125 males) were collected between 2010 and 2013 at 12 out of 60 sampling sites. All 12 sites were characterized by high humidity with marshy areas. Babesia canis DNA was detected in 1 out of 301 (0.3%) questing D. reticulatus in Bavaria. The digital habitat characterization revealed 15 forest areas in Bavaria with similar ecological characteristics as the sites positive for D. reticulatus .

    Abstract Borrelia burgdorferi sensu lato (s.l.) causes the most common tick-borne infection in Europe, with Germany being amongst the countries with the highest incidences in humans. This study aimed at (1) comparing infection rates of B. burgdorferi s.l. in questing Ixodes ricinus ticks from different habitat types in Southern Germany, (2) analysing genospecies distribution by habitat type, and (3) testing tissue and ticks from hosts for B. burgdorferi s.l. Questing ticks from urban, pasture, and natural habitats together with feeding ticks from cattle (pasture) and ticks and tissue samples from wild boars and roe deer (natural site) were tested by PCR and RFLP for species differentiation. B. burgdorferi s.l. was found in 29.8% questing adults and 15% nymphs. Prevalence was lower at the urban sites with occurrence of roe deer than where these were absent. Borrelia burgdorferi s.l. DNA was found in 4.8% ticks from roe deer, 6.3% from wild boar, and 7.8% from cattle. Six genospecies were identified in unfed ticks: Borrelia afzelii (48.6%), Borrelia burgdorferi sensu stricto (16%), Borrelia garinii (13.2%) , Borrelia valaisiana (7.5%), Borrelia spielmanii (6.2%), and Borrelia bavariensis (0.9%). This study shows high infection levels and a great diversity of Borrelia in questing ticks. The presence of roe deer seems to reduce B. burgdorferi s.l. infection rates in tick populations.

    Abstract Equine piroplasmosis (EP) is a tick-borne disease of equids caused by Babesia caballi and/or Theileria equi, which is endemic in many tropical and temperate areas of the world. However, clinical outbreaks of EP in Romania during the last decades have not been reported Therefore, the aim of this paper is (i) to describe a clinical B. caballi outbreak in horses on several farms in Southern Romania using a diagnostic and therapeutic approach and (ii) the molecular diagnostic of EP in an endemic area of Romania. In the first case, a 10-month-old stallion male was presented with lethargy, anorexia, fever (40.9 °C), pale mucosal/mucous/membranes and a marked anemia. In the subsequent weeks, three horses from other farms located in the same area, displayed similar clinical signs. B. caballi was diagnosed in all the horses based on Giemsa-stained blood smears and the diagnosis was further confirmed by polymerase chain reaction (PCR), using a single-round and multiplex PCR and sequencing. All four horses were treated with imidocarb dipropionate, at a dose rate of 2.2 mg/kg body weight (two injections at 48 h apart), and all horses clinically recovered within 24–48 h, post-treatment. This report presents the first molecularly characterized B. caballi outbreak in Romania in clinically affected horses, confirmed by DNA sequencing.

    Abstract To establish the diversity and seasonality of ectoparasite infestation in client-owned dogs in Albania, 602 dogs visiting four small animal clinics in Tirana from March 2010 to April 2011 inclusive were examined for ectoparasites by full body search and total body comb. In addition, ear swab specimens collected from all dogs and scrapings taken from skin lesions suspicious of mite infestation were examined for parasitic mites. Overall, 93 dogs (15.4 %, 95%CI 12.6–18.6) were demonstrated to be infested, and nine species of ectoparasites were identified: Ixodes ricinus, 0.8 %; Rhipicephalus sanguineus s. l., 8.1 %; Demodex canis, 0.2 %; Sarcoptes scabiei, 0.7 %; Otodectes cynotis, 2.8 %; Ctenocephalides canis, 4.8 %; Ctenocephalides felis, 3.0 %; Pulex irritans, 0.2 %; and Trichodectes canis, 0.2 %. Single and multiple infestations with up to four species of ectoparasites concurrently were recorded in 67 (11.1 %, 95%CI 8.7–13.9) and 26 dogs (4.3 %, 95%CI 2.8–6.3), respectively. On univariate analysis, the category of breed (pure breed dogs vs. mixed-breed dogs), the dog’s purpose (pet, hunting dog, working dog), the housing environment (mainly indoors/indoors with regular outside walking vs. yard plus kennel/run), the history of ectoparasiticide treatment and the season of examination were identified as significant (p < 0.05) factors predisposing dogs to various ectoparasites, while the variables dog’s age, gender, the dog’s habitat (city, suburban, rural) and the presence/absence of other pets were not significant predictors. Multivariate logistic regression analysis for factors associated with overall ectoparasitism revealed that dogs treated with ectoparasiticides at least once per year (odds ratio [OR] = 0.24; p < 0.001) had a significantly lower risk of infestation compared with dogs not treated against ectoparasite infestation. Dogs examined during spring, summer and autumn (OR = 7.08, 7.43 and 2.48, respectively; all p < 0.001) had a significantly higher risk of infestation than dogs examined during winter. By providing basic data on the infestation with ectoparasites in client-owned, veterinary-cared-for dogs from Albania for the first time, the results of this survey should emphasize the need of an increase of attention to ectoparasites in dogs by both veterinarians and dog owners.

    Abstract Infections with the tick-borne pathogens Anaplasma phagocytophilum and Babesia spp. can cause febrile disease in several mammalian species, including humans. Wild ruminants in Europe are suggested to serve as reservoir hosts for particular strains or species of these pathogens. The aims of this study were to investigate the occurrence of A. phagocytophilum and Babesia spp. in roe deer (Capreolus capreolus), fallow deer (Dama dama) and mouflon (Ovis musimon orientalis) in Germany, and the diversity and host association of genetic variants of A. phagocytophilum and Babesia species. From 2009 to 2010, 364 spleen samples from 153 roe deer, 43 fallow deer and 168 mouflon from 13 locations in Germany were tested for DNA of A. phagocytophilum and Babesia spp. by real-time PCR or conventional PCR, respectively. Variants of A. phagocytophilum were investigated with a nested PCR targeting the partial 16S rRNA gene, and species of piroplasms were identified by sequencing. DNA of A. phagocytophilum was detected in 303 (83.2%) samples: roe deer, 96.1% (147/153); fallow deer, 72.1% (31/43); and mouflon, 74.4% (125/168). Sequence analysis of 16S rRNA-PCR products revealed the presence of nine different genetic variants. DNA of Babesia spp. was found in 113 (31.0%) samples: roe deer, 62.8% (96/153); fallow deer, 16.3% (6/43); and mouflon, 6.5% (11/168). Babesia capreoli, Babesia sp. EU1 (referred to also as B. venatorum), B. odocoilei-like and a Theileria species were identified. Co-infections with A. phagocytophilum and Babesia spp. were detected in 30.0% of the animals which were tested positive for A. phagocytophilum and/or Babesia spp. Roe deer had a significantly higher percentage of co-infections (60.8%), followed by fallow deer (14.0%) and mouflon (6.5%). Thus, the results suggest that roe deer plays a key role in the endemic cycles of the pathogens investigated.

    Abstract The diverse tick fauna as well as the abundance of tick populations in Romania represent potential risks for both human and animal health. Spotted fever group (SFG) rickettsiae are recognized as important agents of emerging human tick-borne diseases worldwide. However, the epidemiology of rickettsial diseases has been poorly investigated in Romania. In urban habitats, companion animals which are frequently exposed to tick infestation, play a role in maintenance of tick populations and as reservoirs of tick-borne pathogens. Therefore, the aim of the present study was to investigate the occurrence of SFG rickettsiae in ticks infesting dogs in a greater urban area in South-eastern Romania. Adult ixodid ticks (n=205), including Rhipicephalus sanguineus sensu lato (n=120), Dermacentor reticulatus (n=76) and Ixodes ricinus (n=9) were collected from naturally infested dogs and were screened for SFG rickettsiae using conventional PCR followed by sequencing. Additionally, ticks were screened for DNA of Babesia spp., Hepatozoon spp., Ehrlichia canis, and Anaplasma platys. Four zoonotic SFG rickettsiae were identified: Rickettsia raoultii (16%) and Rickettsia slovaca (3%) in D. reticulatus, Rickettsia monacensis (11%) in I. ricinus, and Rickettsia conorii (0.8%) in Rh. sanguineus s.l. Moreover, pathogens of veterinary importance, such as B. canis (21%) in D. reticulatus and E. canis (7.5%) in Rh. sanguineus s.l. were identified. The findings expand the knowledge on distribution of SFG rickettsiae as well as canine pathogens in Romania. Additionally, this is the first report describing the molecular detection of R. conorii in ticks from Romania.

    Abstract Horses affected with the fecal water (FW) syndrome defecate normal feces, but in addition, FW runs out of the anus. The present study aimed to identify management factors associated with FW. Owners of affected horses were recruited through a notice in an equine journal. Responders (n = 42) were asked to complete a questionnaire on their horse. A fecal sample for parasitological examination and a blood sample for serum electrophoresis were taken from the affected horse and a clinically healthy stable mate. In the 37 FW horses, which were group housed or group turned out, there were a surprisingly high number of horses that the owners perceived as being at the lower end of the social hierarchy. Therefore, another 37 owners of horses, which did not suffer from fecal water syndrome, were interviewed on their horses' behavior with the same questionnaire (behavior control [BC] group). There was no significant difference between FW horses and their stable mates for any of the parasitological fecal examinations and the serum electrophoresis profiles. No factors related to feeding could be identified as predisposing for FW. Geldings and paint horses were over represented in the FW horses; 40% of FW horses were considered to be last or second to last in the hierarchy compared to 4% in the BC group; 62% of FW horses compared to 27% in the BC group did not defend their food against other horses. These results suggest that social stress may play a role in the development of FW.

    Abstract The selective treatment of horses is used to decrease the number of anthelmintic treatments by only treating a proportion of animals in the population. One way to select animals for treatment is to identify low and high egg-shedders using faecal egg counts (FEC); then to treat only the high egg-shedders. The value of this method is enhanced if differences among individuals in the level of egg-shedding remain consistent over time. One way to assess the stability of the rankings of animals over time is to measure the repeatability which is defined as the variance between horses divided by the total variance. The repeatability varies between 0 (no consistency in the values) to 1 (perfect consistency). To determine the repeatability of egg-shedding in naturally infected horses over time, 2637 FEC and raw egg counts (REC; i.e. originally counted eggs without multiplication factor) from 303 horses were analysed. The distribution of FEC was more overdispersed than a Poisson distribution. Therefore, a negative-binomial model was used. The within-horse-repeatability of RECs was 0.52. In a second analysis, we excluded horses that were treated with anthelmintic drugs during the study by eliminating all REC within the egg-reappearance-period. Here, the within-horse-repeatability was very similar at 0.53. The results show that egg-shedding of individual horses stays fairly consistent over time. They also show that animals which shed relatively high numbers of nematode eggs can be identified and targeted for treatment.
