A case of leishmaniosis in domestic cats (Felis catus domesticus) is described. The subject showed a nodular lesion on the eyelid. The diagnosis was achieved by serological, parasitological, and light and electron microscopic investigations. By molecular techniques the aetiological agent was identified as belonging to Leishmania infantum, the species implicated in human and canine leishmaniosis in southern Europe. A preliminary study on the prevalence of asymptomatic feline leishmaniosis, performed in the areas where the infected cat was identified, revealed a low seroprevalence of infection: only 1 (0.9%) of the 110 cat sera examined by indirect fluorescent antibody test was positive for anti-Leishmania antibodies. Because clinical signs in feline leishmaniosis are unspecific and similar to those observed in other diseases commonly found in this species, leishmaniosis must be added to the differential diagnosis by feline veterinary practitioners and adequate serologic and histopathologic investigations must be performed in endemic areas. 相似文献

Lipid-dependent Malassezia species have recently been cultured from veterinary specimens. The identification of Malassezia species isolates from animals is important to clarify the epidemiology of these lipophilic yeasts. Malassezia species were cultured from the external ear canals of 63 out of 99 cats with otitis and 12 of 52 (23%) healthy control cats. The rate of isolation in affected animals versus controls was highly significant (P<0.01). Malassezia pachydermatis was isolated as a pure culture in 33 (45.2%) cats, associated with Malassezia globosa and Malassezia furfur in 20 (50%) and 17 (42.5%) animals, respectively. Three different species were isolated simultaneously in three cats (two cats with M pachydermatis, M globosa and M furfur, one subject with M pachydermatis, M furfur and Malassezia sympodialis). M globosa was isolated as the sole species in two animals. The present work confirms the presence of some lipid-dependent species of Malassezia in both healthy and otitic cats. 相似文献

OBJECTIVE: To identify and quantify ocular fungi from healthy donkeys living in the center of Italy. ANIMALS STUDIED: One hundred and two Amiata donkeys were examined. PROCEDURES: Conjunctival swabs from both eyes were seeded onto Sabouraud dextrose agar (SDA) and malt extract agar (MEA), and incubated at 25 degrees C over a 10-day period. Filamentous fungi identification was achieved to the genus level; yeast colonies were identified for macro-micromorphologic and physiological characteristics. RESULTS: Eighty-one donkeys out of 102 (79.4%) were positive for fungi; 47/102 (46.1%) had positive cultures from both eyes. Most frequently recovered fungal genera were Aspergillus spp., Penicillium spp., Cladosporium spp., Acremonium spp. Different fungal genera and/or species were recovered from the same donkey in 43 cases (42.1%). Yeasts were isolated from five subjects; the yeasts were never associated with molds. The number of colony forming units (CFU) ranged from 1 to 100. CONCLUSIONS: Aspergillus was the most commonly isolated fungal genus (33%). This result agrees with the findings of similar surveys carried out in horses. There was a remarkable presence of fungi and perfect forms. These observations may be explained by the optimal conditions for presence and development of fungi in the conjunctival fornix microenvironment in Amiata donkeys. 相似文献

Recent epidemiological features of the zoonotic dermatophyte Trichophyton verrucosum were investigated in 294 calves from 20 farms located in Central Italy. By the combination of microscopic examinations and fungal cultures, the total prevalence rate of T. verrucosum infection was found to be high, with 87.7% of samples yielding positive results and 100% of farms being infected. Farm to farm prevalence of infection varied from 25% to 100% of the examined calves. Prevalence rates were higher in females than males (91.6% versus 84%), in >3-< or =6 than >6-< or =9 month old calves (89.8% versus 85.7%), in purebred than in crossbred (88.5% versus 81.8%), and in symptomatic than asymptomatic ones (95.7% versus 80.4%). T. verrucosum was as prevalent in semi-intensive as in intensive breeding system (88.2% versus 87.6%) but more prevalent in calves raised for meat rather than milk production (91.1% versus 84.9%), and reared under conventional than organic production management system (89.3% versus 82.6%). Prevalence rates were also higher when the cattle present in the farm were of mixed origin, rather than when the whole stock was purchased or was born in the farm (92% versus 88.2% and 85.7%), when other cattle in the farm were showing skin signs (90% versus 84.2%), and at least one case of human ringworm was recorded in the farm (90.9% versus 86.1%). No statistically significant association was found. Therefore, T. verrucosum infection may be more widespread in calves from Central Italy than it was previously thought to be. Calves of any sex, breed, age, and of any of the farm condition considered, are highly exposed to the risk of infection. As calves may play a considerable role as reservoirs of the infection, our results highlight the need to determine the incidence and the importance of T. verrucosum ringworm in personnel involved with cattle care in Italy and elsewhere. 相似文献

Faecal samples were collected from 324 pet reptiles showing no clinical signs, including 28 saurian species (n=192), three ophidian species (n=74) and three chelonian species (n=58). Samples were examined for the presence of intestinal parasites by direct smear and faecal flotation, while direct immunofluorescence assays were used to reveal the presence of Cryptosporidium oocysts and Giardia cysts. Overall, 57.4 per cent of the reptiles were harbouring intestinal parasites. These included oxyurids (16 per cent), coccidia (12.3 per cent), flagellates (9.3 per cent), strongyles (6.8 per cent), coccidia plus oxyurids (4.9 per cent), coccidia plus flagellates (1.8 per cent), coccidia plus strongyles (1.8 per cent), oxyurids plus strongyles (1.2 per cent), oxyurids plus flagellates (1.2 per cent), Cryptosporidium species (1.2 per cent) and strongyles plus flagellates (0.6 per cent). Intestinal parasites were more prevalent in saurians than in ophidians and chelonians, in insectivores than in carnivores, omnivores and herbivores, and in wild-caught than in captive-born reptiles. A highly significant difference was observed for saurians versus chelonians (odds ratio [OR]=2.20, 95 per cent confidence interval [CI] 1.21 to 3.99), insectivores versus herbivores (OR=2.38, 95 per cent CI 1.26 to 4.49) and in wild-caught versus captive-born pet reptiles (OR=2.36, 95 per cent CI 1.27 to 4.40). 相似文献

Microsporum canis is the dermatophyte most commonly responsible for ringworm in cats. The purpose of this paper was to evaluate the in vivo efficacy of oral terbinafine (Lamisil; Sandoz) in the treatment of feline ringworm caused by M canis, and to consider this drug as an alternative to griseofulvin or imidazoles. Fifteen cats infected with M canis were treated orally once daily with 30 mg/kg of terbinafine over a 2-week period. All treated animals were checked for dermatophytes on the last day of treatment, a month later and 3 months after the last administration of the drug. Only 12 cats could be used in the whole trial and 11 of these (92%) showed a complete cure. Terbinafine could be an effective alternative to griseofulvin when fungal resistance or idiosyncrasic intolerance are shown and, compared with griseofulvin, could give a faster rate of cure and less relapses. 相似文献

Specific serodiagnosis of canine leishmaniasis by indirect immunofluorescence, indirect hemagglutination, and counterimmunoelectrophoresis 总被引：3，自引：0，他引：3
The increased prevalence of leishmaniasis in dogs in Mediterranean countries has necessitated use of a reliable specific method of immunodiagnosis. Research was carried out on 88 dogs, among which were 26 with severe clinical leishmaniasis (group A), 15 with mild signs of disease (group B), and 11 without signs of disease (group C); in addition, 15 were healthy (group D) and 21 were affected with various other diseases (group E). Dogs of groups D and E were used as controls. Infection was confirmed by cultural isolation of the parasite. Serotests that were used included the indirect immune fluorescent (IFAT) and indirect hemagglutination (IHAT) tests and counterimmunoelectrophoresis (CIEP); using these tests, specific antibodies against Leishmania infantum were detected in all 88 dogs. Sensitivity of the IFAT was 100% in dogs of groups A, B, and C; for the IHAT, it was 65.38%, 60%, and 54.5%, respectively, and for CIEP, it was 96.1%, 80%, and 72.7%, respectively. For dogs of groups D and E, specificity of the IFAT and IHAT was 100%, and for CIEP, it was 100% for group-D dogs and 90.5 for group-E dogs. Indirect immunofluorescence appeared to be the most specific and sensitive of the 3 tests. 相似文献

A 5‐year‐old indoor male neutered Siamese cat was presented with clinical signs of sneezing and chronic bilateral purulent nasal discharge. Multiple nasal cavity swabs were submitted for bacterial cultures, Mycoplasma felis‐DNA qPCR, and cytology. M felisqPCR was positive and cytomorphologic diagnosis was severe, acute, purulent, rhinitis with intralesional protozoal microorganisms consistent with a Trichomonas spp. Nested PCR (nPCR) confirmed the diagnosis of Tritrichomonas foetus. Systemic therapy with doxycycline for M felis and metronidazole for T foetus was started with remission of clinical signs within 2 weeks; however, symptoms relapsed shortly after therapy was discontinued. This study represents the first documented case of T foetus associated with chronic nasal discharge in a cat, which supports the hypothesis that T foetus can live in the nasal cavity. It is also the first reported case of M felis and T foetus coinfection, which indicates that with mycoplasmal feline upper respiratory tract infections, T foetus should be considered as a coinfecting agent. 相似文献

The effectiveness of enilconazole (4 weekly rinses with a 0.2% solution) or griseofulvin (50mg/kg twice daily for 40 days) following a pre-treatment with oral lufenuron (100mg/kg by-weekly for 8 weeks) was tested on 25 (11+14) Microsporum canis infected cats. Control animals were treated with lufenuron, griseofulvin and enilconazole alone. At day 150 pre-treated animals were culturally negative and clinically cured. While lufenuron alone was found to be ineffective against M canis infection, an immunomodulatory effect of the drug can be suggested, as reported in literature. Its use could be reserved to long-lasting infections, unsuccessfully treated with conventional drugs. Further studies are required to clearly establish the possible adjuvant effect of this molecule when used prior to enilconazole or griseofulvin. 相似文献
