Eimeria spp. from Alpine chamois (Rupicapra rupicapra) in Italy
No full textFaecal samples from Alpine chamois (Rupicapra rupicapra) collected in Italian Eastern Alps in the period from July 1995 to July 1997 proved positive for coccidia. Four Eimeria species were identified, namely E. riedmülleri, E. suppereri (first report in Italy) and E. yakimoffmamatschoulskyi, typical of R. rupicapra, and E. faurei, typical of domestic sheep. All these species have already been described in chamois. Cluster analysis, performed
using oocysts and sporocysts measurements, was applied to validate the classification into the four species of the 307 sporulated oocysts examined. Accounting for the theory of Eimeriidae-host specificity, the species identified as E. faurei could be actually a new and morphologically similar Eimeria sp. of R. rupicapra. The reliability of the morphological identification of coccidia, with special reference to those from wildlife, is briefly discussed
Intestinal helminth parasite community in wolves (Canis lupus) in Italy
No full textFrom 1987 to 1993, 89 wolves (Canis lupus) collected throughout the whole Italian range were examined for intestinal helminth parasites. Twelve species were found, including 5 nematodes (Uncinaria stenocephala, Toxocara canis, Ancylostoma caninum, Trichuris vulpis and Toxascaris leonina) and 7 cestodes (Echinococcus granulosus, Taenia hydatigena, T. multiceps, T. pisiformis, T. ovis, Mesocestoides lineatus and Dipylidium caninum). No significant differences were detected between sexes. T. canis showed higher prevalence and numbers in youngs, while E. granulosus and T. vulpis in adults. Interference between U. stenocephala and A. caninum was detected. Parasite biocenosis was stable in respect to geographical and ecological variables

No full textA three years survey on gastro-intestinal nematode egg output was carried out in four Alpine chamois herds (Rupicapra rupicapra rupicapra) from Belluno province (Italy). Data were analysed in order to detect the influence of cattle presence and chamois density on egg output, and to evaluate the stability of host-parasite relationship. As expected, variations related to the season were present, with the major peak of egg output observed in the summer. Results highlighted an unexpected inverse influence of host density on egg counts. The results are in relation to host-parasite relationship stability. Parasites seem to be able to self-regulate in the absence of parasite-induced host mortality. No effect due to cattle presence was detected
ATTI DEL IV CONGRESSO NAZIONALE DI ECOPATOLOGIA DELLA FAUNA
No full textIl Congresso è organizzato dalla SIEF in collaborazione con l’Associazione Teriologica Italiana (ATIt), il Centro Italiano Studi Ornitologici (CISO) e la Società Italiana di Patologia Ittica (SIPI), la Provincia Verbano Cusio Ossola, il Comune di Domodossola, l'Associazione per lo sviluppo della cultura, degli Studi Universitari e della ricerca nel Verbano Cusio Ossola (ARS.UNI.VCO), il Dipartimento di Medicina Veterinaria dell’Università di Milano (DiMeVet).
Si tratta del principale appuntamento a livello nazionale nel campo dell’ecopatologia della fauna, che ha lo scopo di promuovere il confronto tra ricercatori, operatori della sanità pubblica ed animale, tecnici faunistici, esperti di gestione, appassionati e istituzioni sugli aspetti ecopatologici della gestione e conservazione della fauna, sulle implicazioni di sanità pubblica ed animale legate alla presenza e dinamica di popolazioni selvatiche, sui rapporti tra gli animali selvatici e le attività umane e, infine, sulle ricerche più avanzate in ecopatologia.
Il Volume è articolato in 4 sessioni tematiche ed in uno Workshop di approfondimento. Si affrontano diversi temi, dalla conservazione e gestione alla ricerca, tutti in chiave ecopatologica

No full textUse of flubendazole and fenbendazole for treatment of lung severe infection by the gapeworm cyathostoma bronchialis (Nematoda: Syngamidae) in branta hutchinsii, anser indicus and b. leucopsis exotic geese: An interesting case
Full text linkA 6-year-old female goose (Branta hutchinsii) from a group of ornamental exotic geese was found dead due to severe respiratory failure, followed by emission of haemorrhagic sputum and blood clots from the beak and nostrils, and then collapse. At necropsy, the cause of death was attributed to a total of 76 helminth parasites found in the trachea and lungs, then identified as Cyathostoma bronchialis. The flock was initially treated by feed with flubendazole (1200 g/1000 kg/feed) for 7 consecutive days but, at the reappearance of the respiratory symptoms 10 days after, the animals were given fenbendazole by drinking water (300 mg/L) for 7 consecutive days, but at the reappearance of the respiratory symptoms 10 days after, the animals were given fenbendazole via drinking water (300 mg/L) for 7 consecutive days. Despite these treatments, the respiratory symptoms continued to relapse 10–15 days after the end of drug administration. In the literature, there are no data regarding drugs for the treatment of C. bronchialis infestations in geese, and the use of these drugs in exotic birds occurs as “off-label” use. This case study provides information on C. bronchialis life cycle, which is still poorly studied and poorly documented today. In particular, the case provides useful suggestions for evaluating an appropriate protocol for the treatment of C. bronchialis in geese
An unusual case of fatal Strongyloides stercoralis hyperinfection
No full textA 13-month-old male Yorkshire terrier from Modena (Northern Italy) was submitted to physical examination because of coughing, diarrhea and progressive weight loss, which worsened in the last week of life. Depression and dyspnea were noted on clinical examination. Radiography of the thorax indicated interstitial involvement of the diaphragmatic lobe of the right lung and ultrasound of the abdomen showed a diffuse thickening of the small intestine wall. Blood chemistry was indicative of pan-hypoproteinaemia and low folate and fecal examination revealed numerous Strongyloides stercoralis rhabditiform and vital larvae. The subject died after two days and the anatomo-histopathological and parasitological exams confirmed the morphological features of adult S. stercoralis (a well-known agent of zoonosis). This is the first reported case of Strongyloides in Italy in the dog
Risk factors for Toxoplasma gondii infection in dogs: a serological survey
Full text linkBackground Dogs, as well as a wide variety of other warm-blooded animals, act as intermediate host of Toxoplasma gondii. In dogs, most cases of toxoplasmosis are subclinical, although clinical disease has been sporadically reported. Beyond its role in diagnostic pathways, seropositivity also functions as a reflection of the parasite's spread within the dog's living environment. The aim of the present study was to evaluate the possible risk factor associated with seropositivity to T. gondii in dogs in Central-Northern Italy, analysing 120 dogs sera for the presence of IgG antibodies by indirect fluorescence antibody test (IFAT). Results The population examined was composed of 54.2% hunting dogs, 24.2% companion dogs, 14.2% truffle dogs and 7.5% watchdogs. Thirty-four (29.2%) dogs tested positive for T. gondii IgG, with titres ranging from 1:40 to 1:1280. Seroprevalence and antibodies titres were not related to dog gender, age or function. The logistic regression and ordered logistic regression results indicated that seroprevalence, and antibody titres were significantly higher in dogs cohabiting with cats, exhibiting coprophagy habits, and living constantly outdoors. Notably, the lifestyle factor showed the highest odds-ratios in the study: dogs living constantly outdoors were found to be at approximately 5 times greater risk of testing positive and having higher antibody titres compared to dogs living both indoors and outdoors. Conclusion Both logistic and ordered logistic regression results support the key role of living with cats, engaging in coprophagy behaviours, and maintaining an outdoor lifestyle in increasing the risk of T. gondii infection in dogs. These identified risk factors collectively suggest that both ingesting oocysts, as observed through cat cohabitation and coprophagy, and engaging in predatory behaviours, as possible for outdoor living dogs, are indicating likely sources of T. gondii infection in this host species
