The aim of the study was to determine the burden of Toxoplasma gondii-infections in sheep in Sicily, southern Italy and the risk factors for infection. Sera from 1961 sheep were collected just before slaughtering from 62 farms located in 8 out of 9 Sicilian administrative districts. The sera were analysed for Toxoplasma-specific IgG antibodies using commercially available enzyme-linked immunosorbent assay. Sheep less than 4 weeks old were further analysed by ELISA for Toxoplasma-specific IgM-antibodies. Data on farm size and location were obtained from slaughterhouse sanitary reports and through structured telephone interviews of the veterinary officers from public health districts. The overall seroprevalence of Toxoplasma-specific IgG-antibodies were 49.9% (937/1876) by ELISA. Eighty-seven (54/62) percent of the farms had at least one Toxoplasma-positive animal. All the farms fed the animals outdoor on pasture and only one was claiming organic farming. Having cats on the farm, age of the animals, farm size and the use of surface water sources for drinking were all significantly associated with T. gondii-infected animals on the farm. T. gondii infection in mutton used for human consumption is very prevalent, and eating unprocessed sheep and lamb meat has a high risk of transmitting infections to humans. The presence of cats on the farm, farm size and using surface water as drinking water for the animals were risk factors for infection in sheep, with age as a significant confounder. 相似文献

Bovine anaplasmosis caused by Anaplasma marginale is a disease transmitted by ticks belonging to the Ixodidae family. Southern Italy is considered an endemic zone but environmental and social factors are changing the epidemiology of the disease to expand to previously anaplasmosis-free regions. The available data of published reports of anaplasmosis in Italy together with the data obtained by the National Centre of Reference for Anaplasma, Babesia, Rickettsia and Theileria (C.R.A.Ba.R.T.), allowed to report A. marginale infection in different Italian regions (Lazio, Marche, Campania, Puglia, Basilicata, Calabria, Lombardy, Tuscany, Umbria and Sicily). Cattle are also subject to infection with the related Ixodes ricinus-transmitted pathogen, Anaplasma phagocytophilum that results in reduced milk production in cattle. A. phagocytophilum infect also small ruminants, domestic and wild animals and causes the human granulocytic anaplasmosis. Different studies have been conducted on the presence of A. phagocytophilum in Italy both in the tick vectors and in the wild and domestic reservoirs. Contrary to A. marginale, the prevalence of A. phagocytophilum embraces the whole Italian territory from the Alps to the southern and insular regions. 相似文献

Although Anaplasma marginale was known to be endemic in Italy, the diversity of Anaplasma spp. from this area have not been characterized. In this study, the prevalence of Anaplasma spp. antibodies in randomly selected farm animals collected on the island of Sicily was determined by use of a MSP5 cELISA for Anaplasma spp. and an immunofluorescence test specific for Anaplasma phagocytophilum. Genetic variation among strains of Anaplasma spp. from animals and ticks was characterized using the A. marginale msp1alpha and the Anaplasma spp. msp4 genes. Eight species of ticks were collected and tested by PCR. Seropositivity for Anaplasma spp. and A. phagocytophilum was detected in bovine and ovine samples. All the donkeys were seropositive for A. phagocytophilum but not for Anaplasma spp. Four A. marginale genotypes were identified by msp4 sequences from bovine and tick samples. Two new genotypes of Anaplasma ovis were characterized in sheep. The sequences of A. phagocytophilum from three donkeys proved to be identical to the sequence of the MRK equine isolate from California. Six A. marginale genotypes were found in cattle and one tick using the A. marginale msp1alpha sequences. All genotypes had four repeated sequences in the N-terminal portion of the MSP1a, except for one that had five repeats. The Italian strains of A. marginale contained three repeat sequences that were not reported previously. Definition of the diversity of Anaplasma spp. in Sicily reported, herein is fundamental to development of control strategies for A. marginale, A. ovis and A. phagocytophilum in Sicily. 相似文献

Hepatic biliary cystadenoma is a well-delineated neoplasm in some domestic animals, especially in cats, but it has not been reported in equines. We report on a case of hepatic biliary tumor, incidentally found in a 10-year-old horse, with gross and microscopic features similar to those observed in biliary adenofibroma of humans. The tumor presented as a solid mass measuring 16 cm in diameter and histologically was composed of complex tubulocystic biliary components embedded in an abundant fibrotic stroma. We regarded this tumor as a morphological variant of biliary cystadenoma of domestic animals. Differential diagnoses from other hepatic biliary tumor-like and tumor lesions are provided. 相似文献

A survey for oestrosis was carried out in the slaughterhouse at Messine (Sicily) from May 1996 to April 1998. The heads of sheep from local flocks were collected each month. A total of 841 heads were examined according to a validated procedure. 469 (55.8%) were infested by OEstrus ovis larvae. 4423 larvae were harvested: 1829 first instar larvae or L1 (41.4%), 1286 second instar larvae or L2 (29.1%) and 1308 third instar larvae or L3 (29.6%). The mean larval burden for infected sheep was 9.4 larvae with an average of 3.9 L1, 2.7 L2 and 2.8 L3. No period of hypobiosis was recorded. The proportions of larvae in each of the different larval stages was similar from January to September, however, from October to December the percentage of L1 was higher, indicating a period of slowed development. In order to lower the overall prevalence of this disease, it would be necessary to use a parasiticide effective against O. ovis, for all routine parasite control treatments. 相似文献

Caudal duplication is a rare type of conjoined twinning. The aim of this case report is to describe a case of caudal duplication in a male crossbreed puppy. The puppy was macroscopically and radiographically examined after death. External features included a supernumerary limb projecting from the perineum, complete lack of tail, anal atresia, double penis and absence of scrotal sacs. Internal examination showed anomalies involving the intestine and the urinary system. At x-ray examination, the supernumerary limb showed features similar to that of the normal right hindlimb but showed absence of fibula and tibia and presence of three metatarsi and phalanges. The authors discuss the pathogenic mechanisms of this condition, infrequently reported in veterinary practice, pointing out the importance of embryonic duplications commonly associated with dystocia. 相似文献

Male cross‐breed lamb conjoined twins were sent for examination. The twins came from a farm located in the outskirts of Palermo. The twins were spontaneously delivered and found dead by the farmer. X‐ray examination and necropsy were performed. The deformity was identified as deradelphus cephalo‐thoracoomphalopagus. This condition has never been reported in veterinary literature. Our case reports of male conjoined twins characterized by two separated hearts with their own pericardial sacs and two separated livers. These findings represent a rare condition in conjoined twinning. 相似文献

Toxocara canis (T. canis) is originally a parasite of canine bitches and their pups. The pathogenicity of T. canis infection is enhanced during pregnancy and puppyhood. The aim of this study was to investigate if modification of IFNgamma and IL-10 secretion occurs during infection in pregnant dogs and puppies. Analysis of cytokines secreted could let us hypothesize a role for IL-10 and/or IFNgamma in T. canis infection. We tested T. canis-specific production of IFNgamma and IL-10 by lymphocytes of pregnant dogs and their puppies after in vitro re-exposure to purified excretory/secretory antigen (ESAg) from T. canis. Blood mononuclear cells (BMC) isolated from pregnant dogs and their puppies were cultured in the presence of ESAg. Cultures' supernatants were tested for cytokine levels by ELISA. Results obtained showed that IL-10 concentrations increased during pregnancy in infected animals and in the meantime IFNgamma production decreased. In puppyhood, we observed that, IL-10 concentration decreased with the age of puppies mainly in infected animals while IFNgamma increased. In conclusion, our data suggests that BMC of infected dogs have a particular modification of IL-10 and IFNgamma synthesis. These data could be the basis to design immunotherapeutic approaches. 相似文献
