cystic echinococcosis in sardinia: farmers' knowledge and dog infection in sheep farms.cystic echinococcosis (ce) is one of the most widespread parasitic diseases in sardinia, the second largest mediterranean island where almost 3,558,000 milk sheep were raised extensively. the aim of this survey was to evaluate the level of farmers' knowledge on ce transmission, focusing on the role of human to facilitate the persistence of this zoonosis in sardinia after 14 years after the last campaign against ce. the other goal of the survey is to update on presence of echinococcus granulosus ...201121645971
cystic echinococcosis in the sheep: causes of its persistence in sardinia.the authors analyse the current epidemiological situation of sheep cystic echinococcosis (ce) in sardinia, where the prevalence of ovine ce is still very high (70%) and this parasitosis is also frequently found in the human population. for this reason sardinia represents a peculiar model for ce study, because there are particular conditions that allow echinococcus granulosus to complete its life cycle. some social and economical factors support the persistence of sheep ce: over 3 million sarda b ...200919588262
cystic echinococcosis in equids in italy.between march 2003 and february 2007, the livers and the lungs of 2,231 horses from various italian regions were examined for cystic echinococcosis presence at the time of slaughter. hydatid cysts were found in six horses, namely four from sardinia, one from sicily, and one from tuscany. the location, number, morphology, and fertility of the cysts found were determined. dna was extracted from the germinal layers and protoscoleces of the fertile cysts and polymerase chain reactions (pcr) were per ...200818180956
updates on cystic echinococcosis (ce) in update on cystic echinococcosis (ce) diffusion in italy during 2003-2005 is reported. ce seems to have a sporadic diffusion in the northern part of the country where this disease plays a minor role (prevalence < 1%). recent investigations have shown the occurrence of ce cases in humans from the mountains between reggio emilia and modena, with an average year incidence between 9.4 and 5.6/100,000. in abruzzo prevalences in sheep and cattle are 20.2% and 15.3%, with a fertility of 4.6% and 1.3% ...200616881397
molecular characterization of echinococcus granulosus strains in sardinia.investigations were undertaken to determine the genotypes of the parasite echinococcus granulosus that were present in livestock animals on the island of sardinia. liver, lung, and spleen samples were obtained from 770 sheep, 229 cattle, and 277 pigs slaughtered in sardinia between january 2003 and april 2005, and the number and fertility of hydatid cysts were determined. protoscoleces and/or germinal layer were collected from individual cysts, dna was extracted from 91 samples, and polymerase c ...200616323021
cystic echinococcosis in slaughtered sheep in sardinia (italy).of 771 regularly slaughtered sardinian breed sheep, 580 (75%) were found infected with echinococcus granulosus hydatid cysts. seventy-nine sheep (10.3%) had at least 1 fertile cyst. the prevalence of sheep infected with purulent/caseous cysts, calcified cysts and sterile cysts was 13, 59 and 28%, respectively. the age of sheep was positively associated with the probability of infection that increased 1.15 fold for each further year of age. fertile cysts were found in the lungs of 46 sheep (6%) a ...200616226378
cystic echinococcosis in sardinia: the current role of sheep.cystic echinococcosis is one of the most widespread parasitosis in the mediterranean region. unfortunately this is also true for sardinia for various reasons, among which is the close relationship between sheep and dogs in the farms. this work first epidemiologically analyses hydatidosis in sheep in sardinia and then examines the most important causes of the persistence of these metacestodosis in sheep. the work looks at the factors which are responsible for the enormous quantity of illegal slau ...200416044699
cystic echinococcosis in italy from the 1950s to italy the epidemiological pattern of cistic echinococcosis (ce) is incomplete and the information for most regions is out of date, contradictory, and almost exclusively limited to the intermediate hosts. the disease is found most frequently in particular social and economic conditions: widespread use of extensive or semi-extensive sheep farming, illegal slaughtering, and high numbers of sheepdogs and other types of dogs. the highest incidence in sheep is found in sardinia (70.6-92.8%), sicily ...200416044697
[animal echinococcosis in italy: epidemiological update].cystic echinococcosis (ce) is one of the most widespread parasitoses in the mediterranean region (mr). this is due to various factors, the most important being the close association between man, sheep and dogs in areas where open farming is practised. although this disease has been known for several years and many studies have been carried out, nowadays in italy there are no complete epidemiological data on its diffusion and distribution. the available data show that ce is mainly diffused in tho ...200415305683
study on immunobiology in endoparasites of public health interest: echinococcosis-hydatidosis.cystic echinococcosis caused by echinococcus granulosus is one of the most widespread zoonoses in the mediterranean, endemic in some regions such as sardinia. some aspects of the research conducted in this area are briefly reviewed for an integrated analysis of both epidemiological and immunobiological knowledge, gained from field observations and experimental studies. data on epidemiology in intermediate hosts, immunological assessment of exposure in humans, immune response and th1/th2 polariza ...200112078473
hydatidosis in sardinia: review and sardinia, hydatidosis due to echinococcus granulosus is endemic and constitutes a current and important problem in the economy and public health. this paper reviews the epidemiological aspects, including the geographical distribution, and the socio-cultural factors involved in the dissemination of hydatidosis. hospital data indicate that about 200 people undergo surgery for hydatid cysts every year with an average of 8.8 deaths annually. an average of 80% of the sheep are infected, constituti ...19854002284
[hydatidosis in sardinia. co-involved parameters and hypothesis for a control campaign].although hydatidosis provokes in man and livestock losses of economic significance, there has been no comprehensive study on this disease. this article is an account of sardinia as an important area of echinococcosis-hydatidosis. the incidence and distribution of infection in the intermediate and definitive hosts are reviewed and the current status of hydatid disease is evaluated. the review is divided into main sections: (a) geographical and environmental data; (b) domestic intermediate hosts; ...19853870643
[epidemiology and social/health implications of hydatidosis in sardinia].all surgically treated cases of hydatidosis registered in sardinia from 1969 to 1984 have been analysed. the 16-year period clearly shows that unilocular hydatid disease caused by larvae of tapeworm, echinococcus granulosus, is endemic in sardinia. in this region there are foci of human infection notably in the sheep rearing areas, of nuoro and sassari. the incidence of human hydatidosis shows a marked regional variation varying during the last survey (1982-1984) between 16.9/1000 in the provinc ...19892491290
[distribution of ovine hydatidosis in sardinia, 1987-1988].the prevalence of echinococcus granulosus in sheep was examined in sardinia between june and september 1987-1988. of the examined sheep 243 were being pastured in fenced fields while 1084 were being pastured in open fields. an infection rate of 1.6% was recorded in the first group of sheep, and 86.7% in the second. the prevalence rate differed in various parts of the region, ranging from 79.4% (oristano province) to 95% (nuoro province). of the parasitized sheep 7.9% harboured only fertile cysts ...19892487004
epidemiology of hydatid disease in sardinia: a study of fertility of cysts in sheep.hydatidosis, caused by echinococcus granulosus, is a cyclozoonotic disease of economic significance in sardinia. the life-cycle involves stray and sheep dogs as definitive hosts and sheep, pigs, goats and cattle as intermediate hosts. the most important intermediate host is sheep, due to home slaughtering with ready access of the viscera to dogs. this survey was undertaken in 1987 to ascertain the epidemiological significance of sheep in maintaining the life-cycle. a total of 700 (91.3%) of 767 ...19902230030
