Although these 2 species are genetically different, they can be challenged by a similar range of parasites (i.e. small and large strongyles, and Parascaris spp.). Although equids can demonstrate some level of resilience to parasites, they have quite distinct helminth biodiversity, distribution and intensity among different geographical locations and breeds. Heavily infected donkeys may show fewer clinical signs than horses. Although parasite control is primarily provided to horses, we consider that there may be a risk of drug-resistance parasitic infection through passive infection in donkeys when sharing the same pasture areas. Knowing the possible lack of drug efficacy (<90 or 80%), it is advocated the use of selective treatment for both species based on fecal egg counts. Adult horses should receive treatment when...

The control of these infections is still largely based on the massive use of broad-spectrum anthelmintics, which, however, favored the onset of the anthelmintic resistance. The anthelmintic resistance is a widespread problem of increasing concern in several countries, and regarding mainly BZ (fenbendazole), IMD (levamisole) and LM (ivermectin). At present, there are no reported cases of resistance to moxidectin in Italy, but severs international studies have shown the presence of strongyle populations resistent to moxidectin that represents the molecule of choice for the treatment of GI strongylosis in small ruminants. Aim - The aim of the present study was to evaluate the efficacy of an oral formulation containing moxidectin for the treatment of sheep GI strongylosis raised in central Italy, in order to ...

Recently, in European countries, there has been an increasing interest in donkeys due to their use as pets, onotherapy or milk production. During 2014–2016, a countrywide survey was conducted to determine prevalence and risk factors of principal helminth infections in 1775 donkeys in 77 Italian farms. A questionnaire on management and parasite control practices was filled out for each farm. Faecal samples were examined using a modified McMaster technique, a centrifugation/flotation method and a sedimentation technique. Pooled coprocultures were performed for differentiation of strongylid eggs. Strongyles were the most common parasites detected (84.9%), followed by Dictyocaulus arnfieldi (6.9%), Oxyuris equi (5.8%), Parascaris spp. (3.6%), Anoplocephala spp. (1.0%), Strongyloides westeri (0.3%). Coprocultures revealed an omnipresence of cyathostomins (100%), followed by Strongylus vulgaris (31.0%),...

The aim of this work was to evaluate the presence of several selected TBPs of significant public health concern by molecular methods in I. ricinus recovered from dogs living in urban and suburban settings in central Italy. A total of 212 I. ricinus specimens were collected from the coat of domestic dogs. DNA was extracted from each specimen individually and tested for Rickettsia spp., Borrelia burgdorferi sensu lato, Babesia spp., and Anaplasma phagocytophilum, using real-time and conventional PCR protocols, followed by sequencing. Sixty-one ticks (28.8%) tested positive for TBPs; 57 samples were infected by one pathogen, while four showed coinfections. Rickettsia spp. was detected in 39 specimens (18.4%), of which 32 were identified as Rickettsia monacensis and seven as Rickettsia helvetica. Twenty-two samples (10.4%) tested positive for A. phagocytophilum; Borrelia lusitaniae and Borrelia afzelii were detected in two specimens and one specimen, respectively. One tick (0.5%) was found to be positive for Babesia venatorum (EU1). Our findings reveal the significant exposure of dogs to TBPs of public health concern and provide data on the role of dogs in the circulation of I. ricinus-borne pathogens in central Italy.

The aim of this study was to determine the exposure to SFGR among dogs and feeding ticks in central Italy. A total of 344 dogs and 607 adult ticks (395 Rhipicephalus sanguineus and 212 Ixodes ricinus specimens) collected from the coats of sampled animals were included in the study. Canine serum samples were analyzed by indirect fluorescent antibody technique (IFAT) for IgG antibodies against Rickettsia conorii and Rickettsia rickettsii. All the ticks and buffy coats were processed by a PCR targeting a fragment of gltA followed by sequencing. Overall, 56 dogs (16.3%) tested positive for one or both rickettsial antigens by IFAT with endpoint titers ranging from 1:64 to 1:2048; 38 (11%) serum samples reacted against R. conorii, 46 (13.4%) reacted against R. rickettsii, and 28 (8.1%) reacted simultaneously against both rickettsial agents. All buffy coats were PCR negative. Rickettsial DNA was revealed in 39 (18.4%) I. ricinus and in 10 (2.5%) R. sanguineus specimens. The amplicons sequencing showed three SFGR, that is, R. conorii detected in 10 R. sanguineus specimens and Rickettsia helvetica and Rickettsia monacensis detected in 7 and 32 I. ricinus ticks. Nine out of the 10 R. conorii isolates were obtained from ticks collected from seronegative dogs, and one specimen from a dog tested positive for both R. rickettsii and R. conorii by immunofluorescence assay. Among the seven ticks tested positive for R. helvetica, six were recovered from the coats of seronegative dogs and one from a dog having antibodies against R. conorii; the 32 isolates of R. monacensis were obtained from 28 seronegative and 4 R. conorii/R. rickettsii-positive dogs. The results highlight the non-negligible exposure of the canine population to SFGR in the sampled areas.
