RESUMEN

A dog from Paris (France) was referred with a 2-week history of dry cough, intermittent acute onset of dyspnoea, and acute abdominal pain. A generalised bronchoalveolar infiltrate with a patchy distribution was observed at chest x-rays and computed tomography (CT) scans. Negative results were obtained through several faecal examinations for cardiorespiratory nematodes by using the Baermann technique and at two blood analysis with a commercially available test for the detection of A. vasorum antigen (the first one at the first visit and second one at the control visit, one month later). PCR methods for the identification of A. vasorum and C. vulpis were also accomplished. At the control visit, nematode L1s were found during direct microscopic examination of bronchoalveolar lavage fluid (BALF). Thus, a different antigen-based assay for the detection of A. vasorum was performed with a positive result. Moreover, based on morphology, isolated larvae were identified as Filaroides hirthi. The dog was treated with fenbendazole (50 mg/kg per os once daily) for two consecutive weeks. After five months, the dog was referred again for the intermittent acute onset of dyspnoea and was found to be still positive for F. hirthi larvae at BALF examination. A 15-day treatment regimen with fenbendazole in combination with three subcutaneous injections of ivermectin (0.4 mg/kg, once every two weeks), was then performed. No larvae were detected at two BALF microscopical examinations performed one month apart. Results from this case report underline the importance of including F. hirthi infections in the differential diagnosis of dog bronchopneumonia.

RESUMEN

The common octopus Octopus vulgaris Cuvier, 1798 is extremely important in fisheries and is a useful protein source in most Mediterranean countries. Here we investigated pathogens associated with skin lesions in 9 naturally deceased specimens that included both cultured and wild common octopus. Within 30 min after death, each octopus was stored at 4°C and microbiologically examined within 24 h. Bacterial colonies, cultured from swabs taken from the lesions, were examined using taxonomical and biochemical analyses. Vibrio alginolyticus and V. parahaemolyticus were only isolated from cultured animals. A conventional PCR targeting the 16S ribosomal RNA (rRNA) gene and sequencing were performed on 2 bacterial isolates that remained unidentified after taxonomical and biochemical analysis. The sequence results indicated that the bacteria had a 99% identity with Lactococcus garvieae and Photobacterium swingsii. L. garvieae was confirmed using a specific PCR based on the 16S-23S rRNA internal transcribed spacer region, while P. swingsii was confirmed by phylogenetic analyses. Although all animals examined were found to be infected by the protozoan species Aggregata octopiana localised in the intestines, it was also present in skin lesions of 2 of the animals. Betanodavirus was detected in both cultured and wild individuals by cell culture, PCR and electron microscopy. These findings are the first report of L. garvieae and betanodavirus from skin lesions of common octopus and the first identification of P. swingsii both in octopus skin lesions and in marine invertebrates in Italy.

RESUMEN

Between December 2005 and November 2006, a survey on coccidiosis of wild and captive mouflons living in the Orecchiella Natural Reserve (Tuscany, Italy) was performed on faecal samples collected approximately every two months. A total of 96 samples were collected, 55 of which from wild mouflons and 41 from captive mouflons. On these faecal samples qualitative and quantitative parasitological analyses were performed; moreover, faecal cultures were made in order to identify the involved Eimeria species. Significantly higher prevalence (%) and mean intensity (mean OPG +/- SD) of coccidian infection resulted for captive mouflons (73.17% and 814.6 +/- 1297.2 OPG) comparing to wild mouflons (36.73% and 112.7 +/- 268.7 OPG). Eimeria parva, E ovinoidalis, E. bakuensis, E. ahasata, E. intricata, E. crandallis, E. granulosa, E. faurei and an Eimeria species very similar to the descriptions previously reported for E. arloingi and E. yakimoffmatschoulsky, were isolated.

RESUMEN

Canine urinary capillariosis is caused by the nematode Pearsonema plica. P. plica infection is seldomly detected in clinical practice mainly due to diagnostic limitations. This report describes six cases of urinary capillariosis in dogs from Italy. Recurrent cystitis was observed in one dog, whereas another patient was affected by glomerular amyloidosis. In the remaining animals, the infection was considered an incidental finding. Immature eggs of the parasite were observed with urine sediment examination in 3/6 patients. Increased awareness of the potential pathogenic role of P. plica and clinical disease presentation could help identify infected animals.

RESUMEN

Fifty red foxes (Vulpes vulpes) from the district of Pisa (central Italy) were examined for ectoparasites. Sarcoptic mange was diagnosed on the presence of clearly visible skin lesions with confirmatory demonstration of Sarcoptes scabiei at parasitological and histopathological analysis. Ticks and fleas were collected directly from the carcases during post mortem examination, fixed and identified by morphological examination. For the detection of ear Malassezia and mite infections, cytological and parasitological examinations of ear wax samples were performed. All data were statistically analysed using a χ2 test with the Yates correction. An overall prevalence of 84% for ectoparasitic infections was found in examined subjects. In regard to isolated ectoparasites, 38%, 8%, 82%, 6% and 8% of foxes resulted positive for S. scabiei, Otodectes cynotis, Malassezia spp., fleas (Archaeopsylla erinacei, Pulex irritans, Ctenocephalides canis) and ticks (Ixodes ricinus and Rhipicephalus sanguineus), respectively. Malassezia ear infection was significantly more prevalent in animals older than 1 year (P < 0.01). Prevalence (38%), severity of lesions and poor body conditions observed in most Sarcoptes-infected animals indicate that sarcoptic mange should be considered the most important ectoparasitic infection of red foxes in the examined area.

RESUMEN

Myialges anchora Trouessart, 1906 and M. lophortyx (Furman & Tarshis, 1953) gravid females, surrounded by clusters of eggs, were found strongly inserted into the cuticle of head, thorax, abdomen, femurs and wings of Pseudolynchia canariensis (Macquart, 1840), a hippoboscid fly parasite of the pigeon. This lousefly results obligatory host for ovigerous females of Myialges and for the development of their eggs, and phoretic host because the dispersal of hatching larvae to new hosts may then occur with dispersal of fly carriers. Together with the Myiolges species, not ovigerous females of Ornithocheyletia hallae Smiley, 1970 and Columbicola columbae (Linnaeus, 1758) were found on the pigeon fly.

RESUMEN

Some essential oils obtained from the branches of four Pinus species (P. pinea L., P. halepensis Mill., P. pinaster Soil in Ait., and P. nigra Arnold) have been evaluated for their acaricidal activity by aerial diffusion against the stored food mite Tyrophagus putrescentiae (L.). All the essential oils showed a good efficacy, but P. pinea oil and its two constituents 1,8-cineole and limonene were the most effective compounds, showing 100% acaricidal activity at 8 microL; 1,8-cineole showed the same activity at 6 microL.

RESUMEN

Leishmania infantum, the agent of canine leishmaniasis in Mediterranean countries, and Neospora caninum, a recently recognized protozoal pathogen in dogs, were diagnosed in a 9-month-old Argentine Dogo dog. Both skin lesions and neurological signs were present. Histopathology of cutaneous lesions revealed a suppurative, diffuse dermatitis with numerous intracellular protozoa. Serology was positive for both L. infantum (1:640) and N. caninum (1:800). Double-label immunohistochemical staining of skin samples with hyperimmune serum from L. infantum-infected dogs was positive for protozoa within macrophages, while the polyclonal antibody specific for N. caninum showed positive reactions for protozoa in endothelial cells and fibroblasts. Transmission electron microscopy (TEM) confirmed the infection with both protozoa. This is, to the authors' knowledge, the first case of simultaneous infection with L. infantum and N. caninum in a dog. It is possible that the immunosuppressive effects of Leishmania infection or long-term steroid therapy may have been a contributing factor to the development of N. caninum in this dog.

RESUMEN

The bacterial flora of Psoroptes cuniculi removed from nine naturally infested rabbits was investigated. Mites were collected in sterile glass tubes; half of the mites were surface sterilised, the others were not. All mites were crushed using sterile glass pestles, placed in Buffered Peptone Broth, smeared on to several culture media, by glass rods, and incubated at 37 degrees C for 48 hours, aerobically and/or in 5% CO2. Representative colonies were removed and streaked on to several selective media. Different colour changes of the selective media used, macro and microscopic morphology, ability to grow aerobically, Gram staining, and several biochemical tests evaluated with API test strips, were used for bacterial identification. Staphylococcus aureus, Serratia marcescens and S. odorifera were the bacteria isolated from surface sterilised mites.

RESUMEN

Parasitic otitis associated with Psoroptes sp. mites was diagnosed for the first time in two flocks of goats located in Tuscany, Italy. Some animals presented clinical signs of ear mite infection, but the parasites were also isolated from the ears of two clinically silent goats. A morphometric study was conducted to establish whether there are significant morphological differences between mites collected from the ears of goats and Psoroptes cuniculi collected from the ears of rabbits. Three rabbits were experimentally infected with mites isolated from the auditory canal of goats, while nine goats were infected with mites isolated from rabbits. After three to five months all rabbits and five of the nine goats contained reproducing mite populations in their ears; also the morphometric analysis revealed no difference between rabbit and goat ear mites. It follows that Psoroptes cuniculi represents the etiologic agent of parasitic otitis in both these two animal species.

RESUMEN

Ninety-five (97%) of 98 black siskins (Carduelis atrata) died within 2 months of arrival in Italy from South America with the following clinical sings: rapid weight loss, breast muscle atrophy, congested and distended abdomen, diarrhea, and lethargy. Macroscopically we observed hepato-splenomegaly, pulmonary congestion, and thickening of the interstinal wall. Histologically, lymphomonocytic transmural enteritis, interstitial mononuclear cell infiltrates in the lungs and in the liver, as well as activation of splenic follicles were common features. Large numbers of protozoa belonging to Isospora sp. were observed in various stages of their life-cycle in the intestinal epithelium, and some zoites were found in the extra-intestinal cellular infiltrate as well. No viral or bacterial pathogens were found.

RESUMEN

Air Force radar controllers represent an excellent example of night shift workers, as they are obliged to demonstrate perfect alertness during working hours. We set out: a) to assess the quality of life in these shift workers; b) to identify those with shift work syndrome and c) to evaluate the possible effects of triazolam both on their quality of life and sleep. The results reveal an impairment of the quality of life in shift workers, independently of the presence of a circadian rhythm sleep disorder. Quality of life was more severely impaired in subjects with circadian rhythm sleep disorder. Hypnotic therapy brought about an improvement both in the sleep disorder and in the quality of life of subjects affected by shift work syndrome. Selective alertness tests failed to demonstrate any "sedative carry-over" in the treated patients.

RESUMEN

Generalised acute peritonitis is a relatively frequently pathology which has always been extremely difficult to treat owing to the large number of complications. Considerable progress has been made over the past few years in the surgical treatment of these pathologies following the introduction of new materials accompanied by new techniques: continuous peritoneal lavage (CPL) and laparostomy are the best known. These techniques must be used in carefully selected patients. They allow a marked improvement in results: fewer cases of redo surgery; fewer local and general complications; shorter hospitalisation stay; fewer deaths. These results are possible because these techniques ensure a better cleansing of the peritoneal cavity, with easier removal of necrotic and purulent materials, the main cause of local and general complications.

RESUMEN

OBJECTIVE: Malassezia pachydermatis is a common cause of more widespread dermatitis in dogs (CMD). Recurrences are common, and this disorder can be very troubling for both dogs and for the pet owner. MATERIAL AND METHODS: The treatment of 20 dogs affected by dermatitis due to M. pachydermatis, with Malacalm(®), a commercially available mixture consisting of essential oils (Citrus aurantium 1%, Lavandula officinalis 1%, Origanum vulgare 0.5%, Origanum majorana 0.5%, Mentha piperita 0.5% and Helichrysum italicum var. italicum 0.5%, in sweet almond oil and coconut oil) is reported. The effectiveness of the whole mixture, of component essential oils and of their more represented compounds against clinical isolates was evaluated by a microdilution test. Twenty animals were topically administered the mixture twice daily for 1 month. Ten animals were treated with a conventional therapy based on ketoconazole 10mg/kg/day and chlorhexidine 2% twice a week for 3 weeks. At the end of both treatments animals significantly improved their clinical status. Adverse effects were never noticed. Follow-up visit performed on day 180th allowed to observe a recurrence of clinical signs in all the subjects treated conventionally, while not significant clinical changes were referred in dogs treated with Malacalm(®). The overall MIC value of Malacalm(®) was 0.3%. O. vulgare showed the lowest minimum inhibitory concentrations (MIC), being active at 0.8%, followed by M. piperita (1%), O. majorana (1.3%), C. aurantium (2%) and L. officinalis (4%) while H. italicum did not yield any antimycotic effect up to 10%. Active major compounds were thymol, carvacrol, p-cymene, 1,8-cineol, limonene and menthol. CONCLUSION: The phytotherapic treatment achieved a good clinical outcome, and no recurrence of skin disorders on day 180th was recorded. This herbal remedium appeared to be a safe tool for limiting recurrences of CMD.

RESUMEN

In this study, some in vitro trials were carried out to evaluate the association between Scopulariopsis spp. fungi with Psoroptes cuniculi (Acari: Psoroptidae) and their potential pathogenicity to this mite species. After cultivation on Sabouraud dextrose agar with chloroamphenicol at 26 degrees C for 20 days and macro- and microscopical examinations, from P. cuniculi mites taken from some infested rabbits fungi belonging to the genus Scopulariopsis were isolated. Investigations were carried out to evaluate in vitro the potential pathogenic role of Scopulariopsis to P. cuniculi; to this aim, Scopulariopsis brevicaulis isolated from a cat was tested. In several culture media, the dose-dependent P. cuniculi mortality with different concentrations of S. brevicaulis and the ability of S. brevicaulis to penetrate inside the body of infected mites were evaluated. Results obtained demonstrated that, in the rabbit, Scopulariopsis fungi can be associated with P. cuniculi, and that S. brevicaulis can be an entomopathogen for P. cuniculi in a dose-dependent manner. A more rapid mortality of the mites and a quicker S. brevicaulis growth in plates containing rabbit serum with respect to all other media used were also found. S. brevicaulis demonstrated the ability to invade the body of P. cuniculi.

RESUMEN

The acaricidal activity of Eugenia caryophyllata essential oil was evaluated in vitro and in vivo on Psoroptes cuniculi, a mange mite. In vitro, different concentrations of the oil were tested and the observed mites mortality was compared with that observed in untreated and treated (Acacerulen R) controls. In vivo, six P. cuniculi infected rabbits were topically treated with the oil diluted at 2.5% and compared with untreated and treated control groups of six rabbits each. In vitro, up to the concentration of 0.10% the oil gave highly significant (P<0.01) percentages of mite mortality respect to the untreated controls, but only up to 0.16% it showed the same efficacy of Acacerulen R. In vivo, the treatment with the essential oil cured all infested rabbits and no statistical differences were observed respect to the treated control group. The untreated rabbits remained infested.

RESUMEN

The aim of the present study was to investigate the in vitro and in vivo acaricidal effects of an essential oil of Cinnamomum zeylanicun leaves on Psoroptes cuniculi, a mange mite. In vitro, 2.5 ml of the essential oil diluted at different concentrations, from 10% to 0.03%, in paraffin oil were added to Petri dishes containing all motile stages of P. cuniculi. Mites mortality observed in these dishes was compared with that observed in untreated and treated (AcaCerulen R) control plates. In vivo, one group of six P. cuniculi infected rabbits was topically treated two times at seven days interval with two ml of the essential oil at the concentration of 2.5% in paraffin oil and compared with untreated and treated (AcaCerulen R) control groups of six rabbits each. After 24 h of contact, all concentrations of essential oil between 0.10 and 10% showed a good in vitro acaricidal efficacy if compared with the untreated controls (p<0.01), but only the concentrations between 0.16 and 10% turned out as active as the drug. In vivo, the treatment with the essential oil cured all infested rabbits and no statistical differences were observed with the treated control group.
